Substitute Part Grouping Explanation

Substitution for the Molex 0761658804 is determined by strict equivalence across the following critical parameters:

• Connector type and style: Header, Male Pins, Impact style with guide right orientation
• Electrical specifications: 72 positions, 0.053" (1.35mm) pitch, 24 differential pairs, 30V rating
• Physical configuration: 9×8 matrix, through-hole mounting, press-fit termination
• Material and environmental compliance: Gold contact finish (30.0µin), UL94 V-0, ROHS3 compliant, MSL 1

The substitute parts 0761655804 and 0761659804 maintain identical electrical and mechanical specifications to the main part. The primary distinction is product status: both substitutes are active production parts, whereas the main part is obsolete. Packaging differences (tray vs. standard) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 0761655804 and 0761659804 are functionally equivalent to the obsolete 0761658804 across all electrical and mechanical parameters. Selection between substitutes should be based on:

• Product availability: 0761659804 has higher inventory (1024 pcs) compared to 0761655804 (756 pcs)
• Active production status: Both substitutes are active production parts, ensuring long-term supply chain viability
• Compliance certifications: All parts maintain ROHS3 compliance and UL94 V-0 flammability rating
• Packaging format: Both substitutes are supplied in tray packaging, which may require adjustment to existing procurement workflows if the original part used different packaging

Frequently Asked Questions (FAQ)

Q: Can 0761655804 and 0761659804 be used interchangeably with 0761658804?

A: Yes. Both substitute parts maintain identical electrical specifications (72 positions, 0.053" pitch, 30V rating), mechanical configuration (9×8 matrix, through-hole, press-fit), and material properties (gold contact finish, UL94 V-0). They are direct functional equivalents.

Q: Why is the main part listed as obsolete?

A: The 0761658804 is no longer in active production. The substitute parts 0761655804 and 0761659804 are current production alternatives within the same Impact 76165 series that provide identical performance.

Q: Does packaging format affect compatibility?

A: No. The packaging difference (tray vs. standard) is a logistics consideration only and does not affect electrical or mechanical compatibility. The connector itself is identical.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All three parts are ROHS3 compliant, UL94 V-0 rated, and have MSL 1 (Unlimited) moisture sensitivity level.

Q: Which substitute should be selected for new designs?

A: Either 0761655804 or 0761659804 is suitable for new designs. Selection may be based on inventory availability or existing supplier relationships. Both are active production parts with equivalent specifications.
