I’ll identify the exact 282837-2 variant, research TE Connectivity’s primary documentation and verified alternatives, then create and citation-check the full application guide in the project files.
The TE Connectivity 282837-2 is a 2-position, 5.08 mm-pitch, side-entry PCB screw terminal block with through-hole solder tails and a rising-cage-style wire clamp. It is commonly used to bring field wiring, low-voltage power, or general-purpose control signals onto a PCB where a removable wire is not required.
1. Quick Specifications
Rating note: This passive connector does not have semiconductor-style “recommended operating conditions” and “absolute maximum ratings.” The manufacturer publishes connector operating/rating limits; system voltage, current, PCB copper, creepage/clearance, ambient temperature, wire size, safety standard, and agency approval can require lower application limits.
Created and verified the 282837-2 Application and Usage Guide. It covers ratings, pin usage, wiring, PCB layout, assembly practices, sourcing, and clearly labeled functionally similar alternatives with inline TE drawing citations.
Open items
Exact drop-in compatibility of alternatives is not verified.
TE specifications 108-20166 and 114-20079 were referenced but not fully available.
Suggested next steps
Validate or improve the existing footprint against TE drawing C-282837.
Add polarity and function markings to the footprint.
Review pad geometry for the intended maximum current.

2. Pinout & Connections
This is a non-polarized two-circuit connector. “Pin 1” and “Pin 2” are footprint identifiers only; their electrical functions are assigned by the PCB design.

Description
Best Practice
1
User-defined
First independent screw terminal and PCB solder tail
Assign a clear net name such as VIN, LINE, OUT+, or GND; mark polarity/function on silkscreen and do not rely only on pin number.
2
User-defined
Second independent screw terminal and PCB solder tail
Assign the complementary conductor such as GND, NEUTRAL, OUT−, or a second signal; maintain required creepage and clearance for the applied voltage.
Polarity: The component itself is not polarized. For DC power, consistently use pin 1 for positive and pin 2 for return unless the surrounding product convention requires otherwise, and place visible +/− markings adjacent to the wire-entry side.
3. Standard Application Circuit
Typical two-wire DC power input
Connect pin 1 to the protected input rail (VIN_PROTECTED) through the product’s required fuse, resettable fuse, reverse-polarity device, surge suppressor, or EMI filter.
Connect pin 2 to the input return (GND or VIN−).
Strip each conductor to 5.0–6.0 mm and fully insert it so no bare conductor remains exposed outside the clamp.
Tighten each M3 screw to 0.5 N·m using a torque-controlled screwdriver.
Perform a pull check and inspect for stray strands, incomplete insertion, insulation trapped under the clamp, and exposed copper.
No passive components are intrinsically required by the terminal block. Protection and filtering are determined by the connected circuit:
DC power entry: commonly add a correctly rated fuse, TVS diode, reverse-polarity protection, and local bulk/ceramic capacitance after the protection stage.
Inductive loads or long field cables: consider a TVS, MOV, RC snubber, or flyback path appropriate to the voltage, energy, and switching topology.
Mains or hazardous voltage: use only within the complete product’s certified insulation system. The connector’s 300 VAC rating does not by itself establish adequate PCB creepage, clearance, fuse coordination, touch safety, or regulatory compliance.
Low-level signals: keep the connector away from high-current switching loops and add ESD/surge protection when wiring leaves the enclosure.
4. PCB Layout & Routing Guidelines
Place the block at a board edge with the wire-entry face unobstructed. Reserve screwdriver access above the screws and wire-bend clearance in front of the side-entry openings.
Use a finished plated-hole diameter that never falls below the drawing’s 1.1 mm minimum after drill and plating tolerances. Use adequate annular ring and mechanical copper adhesion for repeated wire-service loads.
Size traces, pours, vias, and solder joints for the actual current and allowed temperature rise. The published 13.5 A contact rating does not imply that a narrow PCB trace can carry 13.5 A.
Prefer broad copper pours on both PCB sides with multiple stitching vias near each terminal for high-current paths. Avoid thermal-relief spokes on high-current pads unless assembly constraints require them; if thermal relief is used, verify current and temperature rise.
Maintain application-standard creepage and clearance between pins and to other copper, board edges, mounting hardware, chassis, and accessible metal. Do not infer regulatory spacing solely from the 5.08 mm pitch.
5. Common Pitfalls / Things to Watch Out For
Treating connector current as PCB current capability. The contact may be rated to 13.5 A, while the selected copper thickness, trace width, vias, pad geometry, ambient temperature, or enclosure cannot safely support that current.
Poor wire preparation or screw torque. Excess strip length, stray strands, ferrules incompatible with the clamp, insulation under the cage, or under/over-torque can cause heating, intermittent contact, or conductor damage. Use the specified 5.0–6.0 mm strip length and 0.5 N·m torque.
Additional checks: confirm the horizontal wire-entry orientation before placement, leave service access, and ensure silkscreen polarity labels remain visible after wiring.
6. Popular Alternatives & Equivalents
Exact drop-in compatibility was not verified for the alternatives below. A matching 5.08 mm pitch and two through-hole pins is insufficient: body dimensions, pin cross-section, hole diameter, wire-entry height, terminal depth, current rating, and agency approvals must all be checked before substitution.

7. Sourcing & Purchasing Guide
Table
Attribute
Details
Primary Distributors
TE Connectivity direct/product page, DigiKey, Mouser, Arrow, TME, RS, Farnell/Newark, and LCSC/JLCPCB where stocked.
Packaging Options
Common listings show bulk/tray packaging. JLCPCB lists a standard/full package quantity of 300; distributor packaging can vary by region and quantity.
Standard MOQ
Often 1 unit for cut/broken-pack distributor orders; manufacturer or assembly-channel full package commonly 300 units. Confirm live MOQ before release.
Sourcing Advice
Prefer TE-authorized or franchised distributors. Match the complete ordering code 282837-2; nearby suffixes identify different pole counts or variants. Verify current lifecycle, country-specific approvals, packaging, RoHS/REACH status, and date code. Avoid assuming marketplace stock is genuine or correctly stored.

Verification status
The numerical claims carrying inline citations were extracted from the active part’s TE Connectivity customer drawing. The published drawing does not provide semiconductor-style absolute maximum versus recommended-condition tables, and the full referenced product/application specifications were not available for independent verification; those limitations are explicitly identified above.
