Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761656608 is determined by strict equivalence across the following critical parameters:

Connector type, style, and position count (144-position Impact header, male pins, guide left)
Pitch specification (0.053" / 1.35mm)
Mounting and termination method (through-hole, press-fit)
Contact layout configuration (48 differential pairs)
Electrical ratings (30V, -55°C ~ 85°C operating range)
Material compliance (UL94 V-0, ROHS3)

The identified substitute parts maintain full electrical and mechanical compatibility with the original specification. Both substitute parts are classified as active products, addressing the obsolescence status of the main part number.

Engineering Selection Recommendations

Both substitute parts (0761653608 and 0761657608) are functionally equivalent to the main part number 0761656608 across all specified electrical and mechanical parameters. The primary distinction between the main part and substitutes is product status: the main part is obsolete while both substitutes are active products.

For new designs and production applications, either substitute part number is suitable for direct replacement. Both maintain identical connector specifications, contact configurations, and compliance certifications (ROHS3, UL94 V-0). The selection between 0761653608 and 0761657608 may be determined by packaging format (both supplied in Tray) and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 0761653608 or 0761657608 be used as direct replacements for 0761656608?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications, including position count, pitch, connector style, mounting method, contact layout, and operating ratings. All three parts are from the Molex Impact 76165 series with equivalent performance characteristics.

Q: What is the primary reason for substitution?

A: The main part number 0761656608 is classified as obsolete. The substitute parts 0761653608 and 0761657608 are active products, ensuring continued availability for production and new design implementations.

Q: Are there differences in packaging between the main part and substitutes?
