Molex 0702800780 Equivalent & Substitute Parts

Part Overview

The Molex 0702800780 is a rectangular connector header designed for through-hole mounting in board-to-board or cable applications. This 64-position, 2-row connector operates at 0.100" (2.54mm) pitch and features male pins with gold-plated mating contacts and tin-plated posts. The part is currently active in production with 1,035 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component selection from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800780 is determined by strict alignment of the following critical parameters:

• Connector type: Header, Breakaway
• Contact type: Male Pin
• Number of positions: 64
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Style: Board to Board or Cable
• Shrouding: Unshrouded
• Number of positions loaded: All

The two qualified substitute parts, both from Amphenol ICC (FCI) under the BERGSTIK® series, meet all critical electrical and mechanical parameters. Both substitute parts maintain the same 64-position, 2-row configuration with identical pitch and row spacing. Contact material differs (Phosphor Bronze vs. Copper Alloy) and contact length specifications vary, but these variations remain within acceptable substitution parameters for this connector category. Both substitutes are active products with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both Amphenol ICC BERGSTIK® parts (77313-124-64LF and 77313-824-64LF) are qualified substitutes for the Molex 0702800780 based on matching critical connector specifications and compliance certifications.

All three parts maintain UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels. The Molex part carries ROHS3 compliance, while both Amphenol ICC substitutes carry RoHS compliance. All parts share the same ECCN (EAR99) and HTSUS classification.

The primary differences between the Molex original and Amphenol ICC substitutes are contact length specifications and insulation material composition. The Molex part features Liquid Crystal Polymer (LCP) insulation with longer contact lengths (0.320" mating, 0.185" post), while both Amphenol ICC substitutes use Thermoplastic insulation with shorter contact lengths (0.266" mating, 0.114" post). These dimensional variations must be evaluated against specific board layout and mating interface requirements.

The Amphenol ICC 77313-824-64LF matches the Molex part's contact finish thickness on mating surfaces (15.0µin), while the 77313-124-64LF provides increased thickness (30.0µin). Both Amphenol ICC parts specify 3A per contact current rating and -65°C to 130°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the Molex 0702800780?

A: The connector must maintain 64 positions in a 2-row configuration with 0.100" (2.54mm) pitch and row spacing. It must be a through-hole mounted header with male pins, push-pull fastening, and solder termination. Contact finish must include gold on mating surfaces and tin on posts.

Q: How do contact length differences affect substitution compatibility?

A: The Molex part specifies 0.320" mating contact length and 0.185" post length, while both Amphenol ICC substitutes specify 0.266" mating and 0.114" post length. These dimensional differences must be evaluated against the specific mating interface and PCB design. Shorter contacts may affect insertion force and mating reliability in applications designed for the longer Molex contacts.

Q: What is the difference between the two Amphenol ICC substitute parts?

A: Both 77313-124-64LF and 77313-824-64LF are BERGSTIK® series headers with identical mechanical and electrical specifications. The primary difference is contact finish thickness on mating surfaces: 77313-124-64LF provides 30.0µin thickness, while 77313-824-64LF provides 15.0µin thickness (matching the Molex original).

Q: Are there compliance or certification differences between the original and substitute parts?

A: All three parts meet UL94 V-0 flammability requirements and carry MSL 1 moisture sensitivity ratings. The Molex part is ROHS3 compliant, while both Amphenol ICC substitutes are RoHS compliant. All parts share EAR99 ECCN classification and 8536.69.4040 HTSUS code.

Q: What insulation material differences exist between the original and substitutes?

A: The Molex 0702800780 uses Liquid Crystal Polymer (LCP) with glass filling, while both Amphenol ICC BERGSTIK® substitutes use Thermoplastic insulation. LCP provides superior thermal and dimensional stability, while Thermoplastic offers different mechanical properties. Material selection should align with application temperature and mechanical stress requirements.

Q: Can the Amphenol ICC parts be used interchangeably with the Molex original in existing designs?

A: Interchangeability depends on specific design constraints. The shorter contact lengths of the Amphenol ICC parts may require PCB layout verification. The different insulation materials and slightly different insulation heights (0.090" vs. 0.100") must be evaluated against board spacing and clearance requirements.
