Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761450135 is determined by strict equivalence across the following critical parameters:

• Connector Series and Style: Impact 76145 series, male pin header configuration
• Electrical Specifications: 180-position array, 0.053" (1.35mm) pitch, 30V voltage rating, 60 differential pairs contact layout
• Physical Configuration: 18 rows × 10 columns, through-hole mounting, press-fit termination
• Material and Environmental Compliance: Gold contact finish (30.0µin), UL94 V-0 flammability rating, ROHS3 compliance, MSL 1 rating
• Operating Conditions: -55°C to 85°C temperature range

The substitute part must maintain identical electrical and mechanical specifications to ensure direct interchangeability without design modification or re-qualification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761451135 is a direct electrical and mechanical equivalent to the 0761450135. All critical parameters—connector type, position count, pitch, array configuration, termination method, contact finish, voltage rating, temperature range, and compliance certifications—are identical.

The primary distinction is product status: the 0761450135 is obsolete, while the 0761451135 is active and currently in production. This status change, combined with identical electrical and mechanical specifications, establishes the 0761451135 as the current production equivalent.

Packaging differs between the two parts (bulk versus tray), which may affect procurement logistics but does not impact functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 0761451135 be used as a direct replacement for the 0761450135?

A: Yes. Both parts are identical in all electrical and mechanical specifications, including connector type, position count, pitch, array configuration, termination method, contact finish, voltage rating, operating temperature range, and compliance certifications. The 0761451135 is the active production equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is product status: 0761450135 is obsolete, while 0761451135 is active. Additionally, packaging differs (bulk versus tray). All functional and electrical characteristics are identical.

Q: Does the packaging difference affect compatibility?

A: No. Packaging format (bulk or tray) does not affect the connector's electrical performance or mechanical fit. The difference is purely logistical and relates to procurement and handling.

Q: Are both parts ROHS3 compliant?
