Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-146277-3 is the direct functional equivalent for the obsolete 104426-1 rectangular connector header. Selection of the substitute part is supported by the following engineering considerations:

Product Status: The 104426-1 is classified as obsolete, creating supply chain risk for new designs and ongoing production. The 5-146277-3 maintains active product status with confirmed inventory availability of 2200 pieces.

Compliance & Certifications: The substitute part 5-146277-3 achieves ROHS3 compliance and REACH Unaffected status, whereas the original part is RoHS non-compliant with undefined REACH status. This improvement in regulatory compliance reduces long-term supply and environmental liability.

Material Composition: The substitute employs Liquid Crystal Polymer (LCP) insulation material in place of thermoplastic, providing enhanced thermal and mechanical stability while maintaining the UL94 V-0 flammability rating.

Contact Finish: The substitute utilizes lead-free tin finish on the post contacts, eliminating lead content in the termination interface while maintaining identical mating contact specifications.

Electrical & Mechanical Equivalence: All critical parameters including pitch, contact geometry, current rating, temperature range, and contact finish specifications are identical between the two parts, ensuring direct functional substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 5-146277-3 be used as a direct replacement for the 104426-1 in existing designs?

A: Yes. The 5-146277-3 maintains identical electrical and mechanical specifications across all critical parameters including pitch, contact geometry, current rating, and operating temperature range. No circuit redesign is required for substitution.

Q: What are the differences between the two parts?

A: The primary differences are product status, compliance certifications, and material composition. The 104426-1 is obsolete with RoHS non-compliant status, while the 5-146277-3 is active with ROHS3 compliance. The insulation material differs (thermoplastic versus LCP), and the post contact finish is lead-free tin instead of tin-lead.

Q: Does the change in insulation material from thermoplastic to LCP affect performance?

A: No. Both materials meet the UL94 V-0 flammability rating and operate within the identical temperature range of -65°C to 105°C. LCP provides enhanced thermal and mechanical stability while maintaining functional equivalence.

Q: Are there packaging differences between these parts?

A: The 104426-1 packaging is not specified in available documentation. The 5-146277-3 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Is the lead-free contact finish on the 5-146277-3 compatible with existing solder processes?

A: Yes. Both parts use solder termination. The 5-146277-3 employs lead-free tin finish on the post contacts, which is compatible with standard lead-free solder assembly processes.

Q: What is the inventory status for each part?

A: The 104426-1 has 930 pieces available as new original stock. The 5-146277-3 has 2200 pieces available as new original stock, providing improved supply availability.

Q: Are there any applications where the 104426-1 cannot be substituted with the 5-146277-3?

A: No. The parts are functionally equivalent across all specified electrical and mechanical parameters. Substitution is valid for all applications within the operating specifications.
