Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800717 is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish substitution validity:

Critical Matching Parameters:

• Connector type: Header, Breakaway
• Contact type: Male Pin
• Number of positions: 18
• 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
• Contact shape: Square
• Material flammability rating: UL94 V-0
• Insulation color: Black

Allowable Variations in Substitute Parts:

• Contact material: Copper Alloy or Phosphor Bronze
• Contact finish - mating: Tin or Gold/Gold GXT™
• Contact finish thickness - mating: Variation permitted
• Insulation material: Liquid Crystal Polymer (LCP) Glass Filled or Thermoplastic
• Insulation height: Minor dimensional variation (0.090" to 0.100")
• Contact length - mating: Variation within functional range
• Contact length - post: Variation within functional range
• Operating temperature range: Extended range acceptable
• Current rating: Equal or greater capacity acceptable
• RoHS compliance: RoHS Compliant or ROHS3 Compliant

The identified substitute parts, Amphenol ICC (FCI) 77313-127-18LF and 77313-824-18LF, meet all critical matching parameters and fall within allowable variations for contact materials, finishes, and insulation composition.

Parameter Comparison

Engineering Selection Recommendations

Both Amphenol ICC (FCI) substitute parts maintain active product status and comply with RoHS regulations. The Molex 0702800717 is ROHS3 Compliant, while the Amphenol ICC alternatives are RoHS Compliant, both meeting current environmental and regulatory requirements.

The primary distinction between the Molex original and Amphenol ICC substitutes lies in contact material composition and surface finish. The Molex part uses Copper Alloy contacts with Tin finish, while both Amphenol ICC alternatives employ Phosphor Bronze contacts with Gold or Gold GXT™ finish. Phosphor Bronze offers enhanced durability and corrosion resistance compared to Copper Alloy, and Gold plating provides superior contact reliability in low-signal applications.

Contact length variations exist between the original and substitutes. The Molex 0702800717 features longer contact lengths (0.320" mating, 0.185" post) compared to the Amphenol ICC parts (0.260"-0.266" mating, 0.105"-0.114" post). These dimensional differences do not affect electrical compatibility in standard through-hole board-to-board applications where mating depth tolerances accommodate such variation.

Insulation material differs between the original (Liquid Crystal Polymer Glass Filled) and substitutes (Thermoplastic). Both materials achieve UL94 V-0 flammability rating and maintain equivalent mechanical and thermal performance in standard operating environments.

The Amphenol ICC substitutes provide specified operating temperature range (-65°C ~ 130°C) and current rating (3A per Contact), whereas the Molex original does not specify these parameters. This additional specification data supports component selection in temperature-critical or high-current applications.

Frequently Asked Questions (FAQ)

Q: Can Amphenol ICC 77313-127-18LF and 77313-824-18LF be used interchangeably with Molex 0702800717?

A: Yes. Both Amphenol ICC parts meet all critical electrical and mechanical parameters required for substitution. The 18-position, 2-row configuration with 2.54mm pitch, through-hole solder termination, and push-pull fastening are identical across all three parts. Differences in contact material, finish, and length do not prevent functional interchangeability in standard board-to-board applications.

Q: What are the differences between Amphenol ICC 77313-127-18LF and 77313-824-18LF?

A: Both parts are functionally equivalent substitutes for the Molex original. The primary difference is contact finish thickness: 77313-127-18LF has 30.0µin (0.76µm) Gold finish thickness, while 77313-824-18LF has 15.0µin (0.38µm). Contact length also varies slightly: 77313-127-18LF mating length is 0.260" (6.60mm) versus 77313-824-18LF at 0.266" (6.75mm). Both maintain identical electrical performance and RoHS compliance.

Q: Why do the substitute parts have shorter contact lengths than the Molex original?

A: Contact length variation is within acceptable tolerance for through-hole connector applications. The shorter contact lengths of the Amphenol ICC parts (0.260"-0.266" mating versus 0.320" for Molex) do not affect mating depth or electrical performance in standard PCB applications where connector receptacles accommodate standard 2.54mm pitch spacing.

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

A: The Molex 0702800717 is ROHS3 Compliant, while both Amphenol ICC substitutes are RoHS Compliant. Both compliance levels meet current regulatory requirements. All three parts achieve UL94 V-0 flammability rating and maintain Moisture Sensitivity Level 1 (Unlimited). The Amphenol ICC parts provide specified operating temperature (-65°C ~ 130°C) and current rating (3A per Contact), which are not specified for the Molex original.

Q: Does the difference in contact material (Copper Alloy versus Phosphor Bronze) affect performance?

A: Phosphor Bronze contacts in the Amphenol ICC substitutes provide enhanced mechanical durability and corrosion resistance compared to Copper Alloy. Gold plating on the Amphenol ICC contacts improves contact reliability and reduces oxidation risk. These material differences represent performance improvements suitable for applications requiring extended service life or enhanced environmental resistance.

Q: Can I mix Molex and Amphenol ICC connectors in the same application?

A: Yes. The identical pitch, position count, and mating interface allow Molex and Amphenol ICC connectors to mate with the same receptacles. However, consistent use of a single manufacturer's connector family within a single assembly is recommended to ensure uniform contact performance and mating characteristics.

Q: What packaging is available for these parts?

A: All three parts are supplied in Bulk packaging. Current inventory includes 1,026 units of Molex 0702800717, 696 units of Amphenol ICC 77313-127-18LF, and 741 units of Amphenol ICC 77313-824-18LF.
