Substitute Part Grouping Explanation
Substitution eligibility for the 641219-2 is determined by strict equivalence across the following critical parameters:
- Connector Type & Series: Must be rectangular receptacle connector from MTA-156 series
- Position Count: Must be 2-position configuration
- Contact Configuration: Must be female socket contacts
- Pitch Specification: Must maintain 0.156" (3.96mm) pitch
- Termination Method: Must support IDC termination
- Wire Gauge Compatibility: Must accommodate 22 AWG wire
- Contact Finish: Must be gold-plated
- Mounting & Fastening: Must be free-hanging in-line with locking ramp fastening
The substitute part 3-641219-2 meets all these criteria and is therefore a direct functional equivalent.
