Molex 0761550134 Equivalent & Substitute Parts

Part Overview

The Molex 0761550134 is a 120-position connector header with male pins designed for through-hole PCB mounting in the Impact 76155 series. This backplane connector features press-fit termination, gold-plated contacts, and is rated for operation between -55°C and 85°C at 30V. The part is currently obsolete, making identification of compatible substitutes essential for legacy system maintenance and board redesigns. The primary substitute maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761550134 is determined by strict equivalence across the following critical parameters:

Connector positioning and pitch (0.053" / 1.35mm spacing with 120 total positions in 12×10 configuration) establish the physical footprint compatibility. The through-hole mounting type and press-fit termination method must remain unchanged to ensure PCB assembly compatibility without design modification. Contact finish specifications (gold plating at 30.0µin thickness) and electrical ratings (30V, -55°C to 85°C operating range) define the functional performance envelope. Compliance certifications (UL94 V-0 flammability, ROHS3, MSL 1) ensure regulatory and environmental compatibility.

The substitute part 0761551134 maintains identical specifications across all these parameters while differing only in product status (active versus obsolete) and packaging format (tray versus unspecified).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761551134 is a direct functional equivalent to the 0761550134. Both parts are manufactured by Molex within the Impact 76155 series and share identical electrical, mechanical, and environmental specifications. The primary distinction is product lifecycle status: the 0761550134 is obsolete while the 0761551134 maintains active production status.

For new designs or board revisions, the 0761551134 is the appropriate selection due to its active availability and continued manufacturer support. For legacy system repairs requiring exact part matching, the 0761551134 provides full compatibility without design modification. Both parts satisfy ROHS3 compliance and UL94 V-0 flammability requirements. The tray packaging of the 0761551134 is standard for active production and does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 0761551134 be used as a direct replacement for the 0761550134 on existing PCBs?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting method, and electrical ratings. No PCB redesign or layout modification is required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 0761550134 is no longer manufactured by Molex. The 0761551134 is the active production equivalent, ensuring continued availability, manufacturer support, and compliance with current standards.

Q: Are the contact finish specifications identical?

A: Yes. Both parts feature gold-plated contacts with 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and corrosion resistance.

Q: Does the tray packaging of the 0761551134 affect compatibility?

A: No. Packaging format does not affect the connector's electrical or mechanical performance. Tray packaging is standard for active production parts and facilitates automated assembly processes.

Q: Are both parts compliant with current environmental and safety standards?

A: Yes. Both the 0761550134 and 0761551134 are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on identical specifications for connector type, position count (120), pitch (0.053" / 1.35mm), row/column configuration (12×10), mounting type (through-hole), termination method (press-fit), contact finish, operating temperature range (-55°C to 85°C), voltage rating (30V), and compliance certifications.
