Molex 0702800808 Equivalent & Substitute Parts

Part Overview

The Molex 0702800808 is an active rectangular connector header designed for through-hole mounting applications. This vertical 40-position connector operates at 0.100" (2.54mm) pitch and supports board-to-board or cable interconnection. The connector features a 2-row configuration with unshrouded design and push-pull fastening. Finding equivalent parts is necessary when addressing supply chain constraints, lead time requirements, or specific application compatibility needs while maintaining electrical and mechanical performance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800808 is determined by strict alignment of the following parameters:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Number of Positions: 40
• 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
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0

The substitute parts listed below meet all these core parameters. Variations in contact length, insulation height, contact material composition, and insulation material type do not preclude substitution when mechanical envelope and electrical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both Amphenol ICC BERGSTIK® parts (77313-122-40LF and 77313-124-40LF) are qualified substitutes for the Molex 0702800808. All three connectors maintain active product status and comply with RoHS and UL94 V-0 flammability requirements.

The Amphenol ICC substitutes employ phosphor bronze contact material in place of copper alloy and thermoplastic insulation instead of glass-filled LCP. These material differences do not affect substitution eligibility when the core electrical interface parameters—pitch, position count, row configuration, contact finish, and fastening mechanism—remain identical.

Both Amphenol ICC parts specify operating temperature range (-65°C ~ 130°C) and current rating (3A per contact), providing defined performance boundaries for thermal and electrical applications. The Molex part does not specify these parameters in the provided data.

Selection between the two Amphenol ICC options depends on mechanical envelope requirements, as contact length and overall connector height differ between 77313-122-40LF and 77313-124-40LF.

Frequently Asked Questions (FAQ)

Q: What determines whether a connector can substitute for the Molex 0702800808?

A: Substitution requires matching connector type (Header, Breakaway), contact type (Male Pin), position count (40), row configuration (2 rows), mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), mounting method (Through Hole), termination (Solder), fastening type (Push-Pull), contact finish (Gold), and flammability rating (UL94 V-0). Contact material and insulation material composition may vary without affecting substitution eligibility.

Q: Are the Amphenol ICC BERGSTIK® parts fully compatible with the Molex C-Grid 70280 series?

A: Yes. Both Amphenol ICC parts meet all core substitution parameters. Compatibility is determined by matching electrical interface specifications and mechanical mounting requirements, which are identical across all three connectors.

Q: What is the difference between Amphenol ICC 77313-122-40LF and 77313-124-40LF?

A: Both parts are functionally equivalent substitutes. The primary difference is contact length and overall connector height. The 77313-122-40LF has a contact length of 0.305" (7.75mm) and overall length of 0.526" (13.35mm). The 77313-124-40LF has a contact length of 0.266" (6.75mm) and overall length of 0.480" (12.19mm). Selection depends on your specific mechanical envelope constraints.

Q: Do the substitute parts have specified operating temperature and current ratings?

A: Yes. Both Amphenol ICC parts specify operating temperature range of -65°C ~ 130°C and current rating of 3A per contact. The Molex part does not include these specifications in the provided technical data.

Q: Are all three connectors RoHS compliant?

A: Yes. The Molex 0702800808 is ROHS3 Compliant. Both Amphenol ICC parts are RoHS Compliant. All three meet flammability requirement UL94 V-0.

Q: What is the difference in insulation material between the main part and substitutes?

A: The Molex 0702800808 uses Liquid Crystal Polymer (LCP) with glass filling. The Amphenol ICC substitutes use thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements and do not affect electrical interface compatibility.
