Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-146253-1 is the direct equivalent for the obsolete 104432-1 within the AMPMODU Mod II rectangular connector series. Selection of the substitute is based on the following engineering criteria:

Product Status Consideration: The 104432-1 is classified as obsolete. The 5-146253-1 maintains active product status, ensuring continued availability, manufacturing support, and supply chain reliability for new designs and production runs.

Compliance and Certification: The 5-146253-1 is RoHS Compliant, whereas the 104432-1 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies these regulatory requirements. Both parts maintain identical UL94 V-0 flammability ratings and REACH/ECCN classifications.

Electrical and Mechanical Equivalence: All critical electrical parameters (3A current rating, -65°C ~ 105°C operating temperature, gold-plated mating contacts) and mechanical parameters (2-position, 2-row configuration, 0.100" row spacing, through-hole mounting, square contact geometry) are maintained. The connector remains functionally interchangeable in existing circuit board layouts and mating applications.

Material Composition: The substitute employs Liquid Crystal Polymer (LCP) insulation material in place of Thermoplastic, providing enhanced thermal stability and mechanical rigidity. The Tin post finish replaces Tin-Lead, aligning with RoHS compliance requirements while maintaining electrical performance within the specified operating parameters.

Termination Capability: The substitute part supports solder termination. The press-fit termination option available on the main part is not offered on the substitute. Applications requiring press-fit termination must evaluate alternative solutions or confirm solder termination compatibility with design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5-146253-1 be used as a direct replacement for the 104432-1 in existing designs?

A: Yes. The 5-146253-1 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, row spacing, contact geometry, current rating, and operating temperature range. The connector is mechanically and electrically interchangeable in board-to-board and cable applications.

Q: What is the difference between the Thermoplastic and Liquid Crystal Polymer (LCP) insulation materials?

A: Both materials meet the UL94 V-0 flammability requirement and operate within the specified -65°C ~ 105°C temperature range. Liquid Crystal Polymer offers superior thermal stability, dimensional consistency, and mechanical strength at elevated temperatures. For applications operating near the upper temperature limit or requiring enhanced mechanical rigidity, LCP provides improved performance characteristics.

Q: Does the change from Tin-Lead to Tin post finish affect connector performance?

A: No. Both finishes provide equivalent electrical conductivity and contact reliability within the specified operating parameters. The Tin finish on the substitute part aligns with RoHS compliance requirements and eliminates lead content while maintaining solder joint integrity and long-term reliability.

Q: Why is the press-fit termination option not available on the substitute part?

A: The 5-146253-1 is optimized for solder termination applications. Designs currently utilizing press-fit termination must transition to solder termination or identify alternative connector solutions. Solder termination provides equivalent mechanical and electrical performance for through-hole mounting applications.

Q: Are there inventory differences between the main part and substitute?

A: The 104432-1 has 1174 pieces in stock (obsolete status). The 5-146253-1 has 790 pieces in stock (active status). Active product status ensures continued manufacturing and replenishment, whereas obsolete inventory is finite and non-renewable.

Q: Is the 5-146253-1 suitable for applications requiring RoHS compliance?

A: Yes. The 5-146253-1 is RoHS Compliant. The 104432-1 is RoHS non-compliant. For applications subject to RoHS directives or customer specifications mandating RoHS compliance, the substitute part satisfies these requirements.

Q: What is the packaging difference between the two parts?

A: The 104432-1 packaging is not specified in the provided data. The 5-146253-1 is supplied in Bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 104432-1 and 5-146253-1 are manufactured by TE Connectivity AMP Connectors and belong to the AMPMODU Mod II connector series, ensuring design consistency and compatibility.

Q: What is the voltage rating for the 5-146253-1?

A: The voltage rating for the 5-146253-1 is not specified in the provided data. The 104432-1 has a 30VAC voltage rating. Confirm voltage requirements with TE Connectivity technical documentation or contact the manufacturer for complete electrical specifications.
