Engineering Selection Recommendations

Active Status Substitutes (Preferred)

The TE Connectivity AMPMODU Mod II series parts 5-146256-4, 5-146257-4, 5-146254-4, 5-146258-4, and 5-146261-4 are actively manufactured and represent the primary substitution options. Parts 5-146256-4 and 5-146257-4 maintain gold-plated mating contacts matching the original specification and carry ROHS3 or RoHS compliance certification. Part 5-146254-4 offers tin-plated mating contacts with ROHS3 compliance. Parts 5-146258-4 and 5-146261-4 provide tin and gold mating finishes respectively with RoHS compliance.

The Amphenol ICC BERGSTIK® II series parts 67996-108HLF and 67996-208HLF are actively manufactured alternatives with extended operating temperature range (-65°C ~ 125°C) and RoHS compliance. These parts differ in contact finish thickness and insulation material composition but maintain core electrical and mechanical compatibility.

Obsolete and Discontinued Status

Parts 4-103328-0-04, 4-103777-0-04, and 4-103783-0-04 are obsolete or discontinued and carry RoHS non-compliance status. These parts employ tin-lead contact finishes and thermoplastic insulation materials inconsistent with modern regulatory requirements. Selection of these parts is not recommended for new designs.

Compliance Considerations

All active substitute parts meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. ROHS3 and RoHS compliant variants are available to support regulatory compliance in automotive, medical, and telecommunications applications. Contact finish variations (gold versus tin) and insulation material differences (LCP versus thermoplastic) are documented parameters that do not affect substitution eligibility but may influence performance in specific environmental or thermal conditions.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0702800632 with a TE Connectivity AMPMODU Mod II connector?

A: Yes. The TE Connectivity AMPMODU Mod II series parts 5-146256-4, 5-146257-4, 5-146254-4, 5-146258-4, and 5-146261-4 meet all core electrical and mechanical parameters: 0.100" (2.54mm) pitch, 8 positions in 2 rows, male pin contacts, through-hole solder termination, and push-pull fastening. All are actively manufactured and RoHS compliant.

Q: What is the difference between gold-plated and tin-plated contact finishes?

A: Contact finish is a provided parameter that varies among substitute parts. Gold-plated mating contacts (0.38µm thickness on the original part) are specified on parts 5-146256-4, 5-146257-4, 4-103783-0-04, and 5-146261-4. Tin-plated mating contacts are specified on parts 5-146254-4 and 5-146258-4. Both finishes meet the core substitution criteria and maintain electrical compatibility.

Q: Are obsolete parts suitable for new designs?

A: No. Parts 4-103328-0-04, 4-103777-0-04, and 4-103783-0-04 are marked as obsolete or discontinued and carry RoHS non-compliance status. These parts employ tin-lead contact finishes and thermoplastic insulation materials. New designs should utilize active status parts with current compliance certifications.

Q: What is the operating temperature range of substitute parts?

A: The original Molex 0702800632 does not specify an operating temperature range. Active substitute parts from TE Connectivity specify -65°C ~ 105°C. Amphenol ICC BERGSTIK® II parts specify -65°C ~ 125°C. These ranges are provided parameters and do not affect substitution eligibility.

Q: Can I use Amphenol ICC BERGSTIK® II connectors as a direct substitute?

A: Yes. Parts 67996-108HLF and 67996-208HLF meet all core parameters: 0.100" (2.54mm) pitch, 8 positions in 2 rows, male pin contacts, through-hole solder termination, and push-pull fastening. These parts are actively manufactured, RoHS compliant, and offer extended operating temperature range (-65°C ~ 125°C). Insulation material and contact finish specifications differ from the original part but do not disqualify substitution.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 3 (2015/863/EU), which restricts the use of specific hazardous substances in electrical and electronic equipment. Parts 5-146256-4, 5-146257-4, and 5-146254-4 carry ROHS3 certification. This is a provided compliance parameter relevant to regulatory requirements in automotive, medical, and telecommunications applications.

Q: Are there differences in contact length between the original part and substitutes?

A: Yes. The original Molex 0702800632 specifies 0.240" (6.10mm) mating contact length and 0.175" (4.45mm) post length. TE Connectivity AMPMODU Mod II substitutes specify 0.230" (5.84mm) mating contact length and either 0.120" (3.05mm) or 0.090" (2.29mm) post length depending on the part number. Amphenol ICC BERGSTIK® II parts specify 0.230" (5.84mm) mating contact length and 0.095" (2.41mm) post length. These are documented parameter variations that do not affect core substitution eligibility.
