Molex 0761558105 Equivalent & Substitute Parts

Part Overview

The Molex 0761558105 is a 120-position backplane connector header with male pins designed for through-hole PCB mounting. This connector features an Impact style with guide right configuration, 12 rows by 10 columns arrangement, and 0.053" (1.35mm) pitch spacing. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications. The substitute part 0761559104 provides functional continuity with identical electrical and mechanical specifications while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 0761559104 qualifies as a direct equivalent based on the following critical parameters that determine substitution eligibility:

Electrical Parameters: Identical voltage rating (30V), operating temperature range (-55°C ~ 85°C), and contact finish specifications (gold, 30.0µin thickness).

Mechanical Parameters: Matching connector configuration with 120 positions, 0.053" (1.35mm) pitch, 12 rows by 10 columns, Impact style with guide right orientation, through-hole mounting, and press-fit termination.

Compliance Parameters: Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 classification.

Functional Equivalence: Both parts belong to the Molex Impact 76155 series with identical contact layout (40 differential pairs) and black color specification.

The primary distinction is product status: the main part (0761558105) is obsolete, while the substitute (0761559104) maintains active status. Packaging differs (main part unspecified versus substitute in Tray), but this does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761559104 is the direct substitute for the obsolete 0761558105. Selection of the active part is justified by:

Product Status: The substitute maintains active manufacturing status, ensuring availability for new designs and ongoing production requirements. The main part's obsolete classification creates supply chain risk.

Compliance Continuity: Both parts maintain identical ROHS3 compliance and UL94 V-0 flammability certification, supporting regulatory requirements across applications.

Electrical and Mechanical Equivalence: Complete parameter alignment across voltage rating, operating temperature, contact specifications, and mechanical configuration ensures direct PCB-level compatibility without design modification.

Packaging Consideration: The substitute is supplied in Tray packaging, which is standard for production environments and does not affect connector performance or installation procedures.

Frequently Asked Questions (FAQ)

Q: Can the 0761559104 be used as a direct replacement for the 0761558105 without PCB redesign?

A: Yes. Both parts share identical electrical and mechanical specifications, including connector type, position count, pitch, mounting method, and termination style. No PCB layout modification is required.

Q: What is the significance of the obsolete status for the 0761558105?

A: Obsolete status indicates the part is no longer manufactured. The 0761559104 provides functional continuity for applications requiring this connector configuration while ensuring ongoing supply availability.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 classification. Regulatory requirements are satisfied by either part.

Q: Does the Tray packaging of the 0761559104 affect installation or performance?

A: No. Packaging format is a logistics consideration only. The connector itself is identical in electrical and mechanical function regardless of packaging method.

Q: What parameters must match for substitution eligibility in the Impact 76155 series?

A: Critical parameters include position count (120), pitch (0.053"), connector style (Impact, Guide Right), mounting type (Through Hole), termination method (Press-Fit), voltage rating (30V), operating temperature range (-55°C ~ 85°C), and contact finish specifications (gold, 30.0µin).
