Symbol cross-check

Result

CheckResultNotes
Pin countPassSymbol has 14 terminals, matching the datasheet requirement to match pin count exactly
Pin numberingPassPins 1-14 are present
Functional groupingMostly passThe terminal naming pattern matches the CA3046 structure: Q1/Q2 pair plus Q3/Q4/Q5 isolated devices
Pin descriptionsFlagNo Pin Description properties are populated
Pin typesFlagAll terminals are currently Unspecified
Symbol clarityMinor flagPin 3 is labeled E, which is probably the common emitter node of the differential pair, but the label is a bit ambiguous without a description
Footprint cross-check

Result

CheckResultNotes
Package familyLikely passProject assets indicate DIP14_300_LIT, which is consistent with a 14-lead PDIP
Pad countLikely passThe project has 14 corresponding pad/terminal names
Full dimensional verificationIncompleteI can confirm package family/count alignment, but I did not get enough geometric detail from the current layout data to verify every pad dimension and spacing numerically
Pin-level issues I found

Main mismatches / gaps

IssueSeverityDetails
Missing Manufacturer NameMediumShould be filled from the chosen datasheet source
Missing package metadata propertyMediumFootprint exists, but no explicit package property is set
All terminal Pin Types are UnspecifiedHighERC usefulness is reduced
No Pin DescriptionsMediumThe symbol is usable, but not self-documenting
No section/group/orientation metadataLowNot required for a simple 14-pin part, but still useful
Overall assessment
  • Good: pin count and high-level symbol topology look consistent with CA3046.
  • Good: footprint/package family appears consistent with 14-pin PDIP.
  • Needs cleanup: terminal metadata is incomplete.
  • Main risk: the symbol is structurally close, but because pin types and descriptions are missing, it is not fully verified/documented yet.
If you want, I can do the next pass and populate:
  • Manufacturer Name
  • Package or Case Code
  • Pin Type for all 14 terminals
  • Pin Description for all 14 terminals
and then give you a stricter pin-by-pin verification table.
Fix all mismatches
Clean up power parts
Check missing footprints

CA3046 thumbnail
RF Transistor 5 NPN 15V 50mA 550MHz 300mW Through Hole 14-PDIP The CA3046 contains five matched NPN bipolar junction transistors (BJTs) integrated on a single silicon chip. These transistors share a common substrate but are electrically isolated from each other, allowing flexible circuit configurations. It is commonly used in analog circuits where closely matched transistor characteristics are required, such as differential amplifiers and current mirrors. Key Features Type: NPN transistor array IC Number of Transistors: 5 matched transistors Integrated Structure: Monolithic silicon chip Isolation: Each transistor is individually accessible Matching: Good thermal and electrical matching between transistors Package: Typically 14-pin DIP or SOIC (varies by manufacturer) Electrical Characteristics (typical) Collector-emitter voltage (Vce): up to ~15 V (varies by variant) Collector current: a few milliamps per transistor (low-power signal applications) Frequency response: suitable for low to medium-frequency analog circuits Operating temperature: industrial range (depends on manufacturer spec) Typical Applications Differential amplifiers Current mirrors Temperature sensing circuits Signal processing circuits Oscillators and timing circuits General-purpose analog transistor building blocks #CommonPartsLibrary #Transistor # BJT #RF-transistor #Bipolar
