Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800813 is determined by strict alignment of the following critical parameters:

Connector Configuration: 50-position, 2-row header with 0.100" (2.54mm) mating pitch and 0.100" row spacing
Contact System: Male pin contacts with gold mating finish and tin post finish
Mounting and Termination: Through-hole solder termination with push-pull fastening
Electrical and Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, and MSL 1 moisture sensitivity

The substitute parts listed below meet these core electrical and mechanical requirements, enabling direct functional equivalence in applications requiring 50-position 2.54mm-pitch rectangular connector headers.

Engineering Selection Recommendations

All three parts—Molex 0702800813, TE Connectivity 7-146252-5, and Amphenol ICC 77313-124-50LF—maintain active production status and meet UL94 V-0 flammability requirements with RoHS compliance and MSL 1 moisture sensitivity ratings. Selection among these equivalents should be based on:

Molex 0702800813: Primary choice where original specification is required. Insulation material specified as LCP with glass fill provides enhanced mechanical properties.

TE Connectivity 7-146252-5: Functionally equivalent with LCP insulation (non-glass-filled). Supports operating temperature range of -65°C to 105°C and 3A current rating per contact.

Amphenol ICC 77313-124-50LF: Functionally equivalent with thermoplastic insulation and phosphor bronze contact material. Supports extended operating temperature range of -65°C to 130°C and 3A current rating per contact. REACH-affected status noted.

All parts share identical mating pitch, row spacing, contact configuration, and termination method, ensuring mechanical and electrical interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the Molex 0702800813?

A: Substitution requires matching the 50-position, 2-row configuration with 0.100" (2.54mm) mating pitch and row spacing, male pin contacts with gold mating finish, through-hole solder termination, push-pull fastening, UL94 V-0 flammability rating, and RoHS compliance with MSL 1 moisture sensitivity.

Q: Are the TE Connectivity and Amphenol ICC parts mechanically compatible with the Molex connector?

A: Yes. Both substitute parts maintain identical mating pitch, row spacing, contact type, and termination method. Physical board layout and mating interface compatibility are preserved.

Q: What are the differences in contact material between these parts?

A: The Molex and TE Connectivity parts use copper alloy contacts, while the Amphenol ICC part uses phosphor bronze. Both materials are suitable for the specified gold mating finish and tin post finish application.

Q: Do all three parts support the same operating temperature range?

A: No. The Molex part does not specify an operating temperature range. The TE Connectivity part supports -65°C to 105°C, while the Amphenol ICC part supports the extended range of -65°C to 130°C.

Q: What is the difference in insulation material between the parts?

A: The Molex part specifies LCP with glass fill. The TE Connectivity part specifies LCP without glass fill. The Amphenol ICC part uses thermoplastic insulation. All meet UL94 V-0 flammability requirements.

Q: Are current and voltage ratings specified for all parts?

A: The Molex part does not specify current or voltage ratings. The TE Connectivity and Amphenol ICC parts both specify 3A current rating per contact. Voltage ratings are not specified for any of the three parts.

Q: What is the REACH status of these parts?

A: The Molex and TE Connectivity parts do not specify REACH status. The Amphenol ICC part is noted as REACH-affected.
