Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

Audit complete. The Panasonic datasheet URL was already present, so I did not change it; I added missing pin descriptions and set all relay terminals to Passive. No hard symbol/footprint mismatches were found; the only caution is to visually confirm polarized coil polarity against the original PDF artwork before production release due to garbled OCR.

Note: A generic datasheet query can surface a standard-contact 200 mW coil table. The exact product page and exact TQ2SA-L2-3V-Z / ATQ221SAZ row identify this part as the 140 mW SA type; use the 140 mW, 46.7 mA, 64.3 ohm values for this MPN.
Symbol Pin Cross-Check
Existing terminal mapping after review:

Table

PinSymbol terminalFunction
1COIL1+Set coil positive terminal
2NC1Normally closed contact, pole 1
3COM1Common contact, pole 1
4NO1Normally open contact, pole 1
5COIL1-Set coil negative terminal
6COIL2-Reset coil negative terminal
7NO2Normally open contact, pole 2
8COM2Common contact, pole 2
9NC2Normally closed contact, pole 2
10COIL2+Reset coil positive terminal
The symbol exposes all 10 relay terminals and the contact groups match the Panasonic 2 Form C topology. The Panasonic datasheet schematic is printed as top/bottom views and the OCR output is partially garbled; the current symbol naming follows the visible pin numbering/contact grouping and common TQ2SA-L2 pin convention. Coil polarity should still be visually checked against the PDF schematic before releasing the library part because polarized latching relay coil polarity is safety-critical.
Footprint Cross-Check
Existing footprint pads:

Table

1-5.08, +4.781.00 x 2.94SMD rectangle
2-2.54, +4.781.00 x 2.94SMD rectangle

9-2.54, -4.781.00 x 2.94SMD rectangle
10-5.08, -4.781.00 x 2.94SMD rectangle
The footprint matches the Panasonic SA recommended PC board pattern dimensions captured from the datasheet: 2.54 mm pad pitch along each row, 9.56 mm row spacing, and 1.00 mm x 2.94 mm recommended SMD pads. Body/fab outline is 14 mm x 9 mm, matching the datasheet family dimensions. Courtyard is larger than the relay body and acceptable.
Mismatches / Issues Found

Table

SeverityItemStatus
LowTerminal pin descriptions were missing / generic before audit.Fixed: added Pin Description for all 10 terminals.
LowTerminal Pin Type values were Unspecified.Fixed: set all terminal Pin Type values to Passive.
LowPackage field was not found as a project-level property in semantic project search.Not changed; footprint asset and product description clearly identify SA surface-mount terminal package.
LowPin count was not found as a project-level property in semantic project search.Not changed; project context reports Pads: 10 and symbol/footprint both have 10 pins/pads.
CautionOCR extraction of Panasonic schematic polarity is imperfect.No symbol/footprint mismatch found, but manual visual confirmation of coil polarity in the PDF is recommended before production release.
Updates Made
  • Confirmed the official Panasonic datasheet URL is already present; no Datasheet URL update required.
  • Added pin descriptions for all 10 schematic terminals.
  • Changed all terminal Pin Type values from Unspecified to Passive.
Overall Result
No hard symbol or footprint mismatches were found. The footprint dimensions match the SA type recommended PCB pattern, the symbol exposes the correct 10 relay terminals, and the project already references the official Panasonic datasheet. The only issues found were incomplete pin metadata, which have been corrected, plus a caution to visually verify polarized coil polarity against the original PDF artwork before release.

Flat, 5 mm 2 Form C, 2 A, relays Telecom Relay DPDT (2 Form C) Surface Mount
The TQ2SA-L2-3V-Z is a compact surface-mount DPDT (2 Form C) telecom/signal relay from Panasonic Industry designed for low-power switching applications. It features a dual-coil latching mechanism, allowing the relay to maintain its state without continuous coil power, making it suitable for battery-powered and energy-efficient systems. This relay is commonly used in telecommunications equipment, industrial controls, measurement devices, and embedded electronic systems.
Key Features DPDT (2 Form C) contact configuration 3V DC dual-coil latching relay Low power consumption: approximately 140 mW Compact SMD package: only 5.6 mm height Surface-mount gull-wing terminals Sealed construction for automatic washing compatibility High switching capability: up to 2 A Wide switching voltage range: up to 125 VAC / 220 VDC Fast operate/release time: approx. 4 ms High dielectric strength and surge resistance Wide operating temperature: −40°C to +85°C Gold-clad AgNi contacts for reliable low-level signal switching Tape-and-reel packaging (“Z” suffix) for automated assembly #CommonPartsLibrary #relay
