• Contact material (Phosphor Bronze)
• Contact finish and thickness (Gold, 50.0µin)
• Ratings (Cat3)
• Shielding configuration (Unshielded)

Mechanical Compatibility Parameters:

• Mounting type (Surface Mount)
• Orientation (90° Angle, Right)
• Termination method (Solder)
• Housing material (Polyamide/Nylon)
• Tab direction (Down)
• Board lock feature presence

Environmental Parameters:

• Operating temperature range (-40°C ~ 85°C)

The substitute part 5557314-1 maintains identical electrical and mechanical specifications across all critical parameters, ensuring direct functional equivalence. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The TE Connectivity 5557314-1 is the direct functional equivalent to the obsolete 557314-1 modular connector. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The 557314-1 is classified as obsolete, creating supply chain risk for new designs and production continuity. The 5557314-1 maintains active product status, ensuring ongoing manufacturer support and availability.

Compliance and Certification: The 5557314-1 is RoHS Compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part satisfies regulatory requirements. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Electrical and Mechanical Equivalence: All critical electrical parameters (contact material, finish, ratings, shielding) and mechanical parameters (mounting, orientation, termination, housing) are identical between the two parts. Direct substitution is supported without circuit or layout modifications.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

Packaging and Availability: The substitute part is supplied in tray packaging with higher inventory levels (3423 units versus 1158 units), supporting production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5557314-1 be used as a direct replacement for the 557314-1 in existing designs?

A: Yes. The 5557314-1 is electrically and mechanically identical to the 557314-1 across all critical parameters including connector type, contact configuration, mounting orientation, termination method, and operating temperature range. No circuit modifications or PCB layout changes are required.

Q: What is the primary reason to transition from 557314-1 to 5557314-1?
