Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761450127 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins, Impact series)
• Position count and arrangement (180 positions, 18 rows × 10 columns)
• Pitch specification (0.053" / 1.35mm)
• Mounting and termination method (Through Hole, Press-Fit)
• Contact material and finish (Gold plating, 30.0µin thickness)
• Electrical ratings (30V, -55°C ~ 85°C operating range)
• Compliance certifications (UL94 V-0, ROHS3)

The substitute part Molex 0761451127 meets all these criteria with identical electrical and mechanical specifications. The primary distinction is packaging format and product status, with the substitute available in active production status.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761451127 is a direct functional equivalent to the obsolete 0761450127. Both parts are manufactured by Molex within the Impact 76145 series and share identical electrical specifications, mechanical dimensions, contact configuration, and compliance certifications. The substitute part maintains ROHS3 compliance and UL94 V-0 flammability rating, ensuring regulatory alignment with the original component.

The primary advantage of selecting the 0761451127 is its active product status, which ensures ongoing availability and manufacturing support. The packaging difference (tray format for the substitute versus standard packaging for the original) does not affect functional performance or PCB integration. Both parts are suitable for applications requiring 180-position backplane connectivity with press-fit termination in the -55°C to 85°C operating range at 30V maximum voltage.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761451127 be used as a direct replacement for the 0761450127 in existing PCB designs?

A: Yes. The 0761451127 is electrically and mechanically identical to the 0761450127. All critical parameters including position count, pitch, mounting type, contact finish, and electrical ratings are equivalent. No PCB redesign is required.

Q: What is the significance of the product status difference between these parts?

A: The 0761450127 is classified as obsolete, indicating Molex has discontinued production. The 0761451127 maintains active product status, meaning it is currently manufactured and available through authorized distributors. This ensures long-term supply chain reliability for new procurements and system support.

Q: Does the packaging difference affect component performance or installation?

A: No. The packaging format (tray for the substitute) is a logistics consideration only. It does not impact electrical performance, mechanical fit, or PCB assembly compatibility. Both parts are suitable for automated and manual assembly processes.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the 0761450127 and 0761451127 are ROHS3 compliant and carry UL94 V-0 flammability certification. The substitute part maintains identical compliance status, making it suitable for applications with regulatory requirements equivalent to the original component.

Q: What are the key parameters that define substitution eligibility for this connector?

A: Substitution is based on strict equivalence in connector type, position count (180), pitch (0.053"), row/column configuration (18×10), mounting method (through-hole), termination type (press-fit), contact finish (gold), voltage rating (30V), operating temperature range (-55°C to 85°C), and compliance certifications (ROHS3, UL94 V-0).
