Molex 0761550138 Equivalent & Substitute Parts

Part Overview

The Molex 0761550138 is a 120-position backplane connector header with male pins designed for through-hole PCB mounting. This connector is part of the Impact 76155 series and features press-fit termination with gold-plated contacts rated for 30V operation across an extended temperature range of -55°C to 85°C.

The 0761550138 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance where this connector remains in active use.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761550138 is determined by strict equivalence across the following critical parameters:

Connector configuration: 120 positions arranged in 12 rows × 10 columns with 0.053" (1.35mm) pitch spacing Electrical and mechanical interface: Male pin header with through-hole press-fit termination Contact specifications: Gold plating at 30.0µin thickness with 30V voltage rating Environmental compliance: UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 rating Operating conditions: -55°C to 85°C temperature range

The substitute part identified below maintains full electrical and mechanical compatibility with the original specification. Packaging differences do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761551138 is the direct functional equivalent of the 0761550138. Both parts are manufactured by Molex within the Impact 76155 series and maintain identical electrical, mechanical, and environmental specifications.

The primary distinction is product status: the 0761550138 is obsolete, while the 0761551138 remains in active production. This status difference makes the 0761551138 the preferred selection for new designs and ongoing supply requirements.

Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting current regulatory requirements. The MSL 1 rating indicates unlimited shelf life under standard storage conditions.

Packaging format differs between the two parts (the 0761551138 is supplied in trays), but this does not affect functional interchangeability or PCB-level performance.

Frequently Asked Questions (FAQ)

Q: Are the 0761550138 and 0761551138 electrically interchangeable?
