Substitute Part Grouping Explanation

Substitute parts for the Molex 0702800645 are qualified based on the following critical parameters that determine functional equivalence:

Connector Configuration: 34 positions, 2 rows, 0.100" (2.54mm) mating pitch and row spacing
Mounting and Termination: Through-hole solder termination with push-pull fastening
Contact System: Male pin contacts with square contact shape
Electrical and Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 moisture sensitivity

All identified substitute parts meet these core parameters. Variations in contact length, insulation material, contact finish specifications, and operating temperature ranges are secondary parameters that may influence selection based on specific application requirements but do not disqualify functional substitution.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and meet the core functional requirements of the Molex 0702800645. Selection among these alternatives should be based on the following considerations:

TE Connectivity 6-146256-7 (AMPMODU Mod II series) provides direct functional equivalence with ROHS3 compliance and operates across -65°C to 105°C. This part is suitable for general purpose applications where the operating temperature range is within specification.

Amphenol ICC 67997-134HLF (BERGSTIK® II series) and 77313-101-34LF (BERGSTIK® series) both offer extended operating temperature ranges to 130°C with REACH compliance status. The BERGSTIK® II variant (67997-134HLF) is classified as a Header without breakaway designation, while the BERGSTIK® (77313-101-34LF) maintains breakaway capability. Both support 3A per contact current rating.

Sullins PBC17DAAN and PEC17DAAN provide alternatives with polybutylene terephthalate (PBT) insulation material and phosphor bronze contacts. The PBC17DAAN features gold mating contact finish, while PEC17DAAN uses tin finish. Both operate across -65°C to 125°C and carry ROHS3 compliance with REACH unaffected status.

All substitute parts are available in bulk packaging with current inventory levels exceeding 996 units.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702800645 be directly replaced with any of these substitute parts?

A: Yes, all listed substitute parts share the critical functional parameters: 34 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing, through-hole solder termination, and push-pull fastening. Physical board layout compatibility should be verified due to variations in overall contact length and insulation height.

Q: What is the significance of the contact length differences between parts?

A: Contact length variations affect board thickness compatibility and mating depth. The Molex 0702800645 has a longer overall contact length (0.505") compared to substitutes (0.425" to 0.450"). Applications with specific board thickness requirements or mating depth constraints must account for these dimensional differences.

Q: Are there differences in environmental compliance between these parts?

A: All parts meet UL94 V-0 flammability requirements and ROHS3 compliance. The Amphenol ICC parts carry REACH compliance status, while Sullins parts are REACH unaffected. The TE Connectivity part has REACH status listed as vendor undefined. Applications subject to REACH regulations should specify accordingly.

Q: How do contact material and finish specifications affect substitution?

A: The Molex part uses copper alloy with gold mating finish, while most substitutes use phosphor bronze with either gold or tin finish. Contact material and finish affect electrical conductivity, corrosion resistance, and long-term reliability. Applications requiring specific contact material properties should be evaluated against the substitute specifications.

Q: What operating temperature range should be considered for substitution?

A: The Molex 0702800645 does not specify an operating temperature range. Substitute parts range from -65°C to 105°C (TE Connectivity) to -65°C to 130°C (Amphenol ICC). Applications operating outside the -65°C to 105°C range should select substitutes with appropriate temperature ratings.

Q: Are all substitute parts available in the same packaging format?

A: Yes, all substitute parts are supplied in bulk packaging, consistent with the Molex original part. Inventory levels range from 996 to 1531 units across the substitute options.
