Molex 0761553604 Equivalent & Substitute Parts

Part Overview

The Molex 0761553604 is a 192-position backplane connector header designed for through-hole PCB mounting applications. This Impact series connector features male pins with press-fit termination and is configured as a 12×16 matrix with 0.053" (1.35mm) pitch spacing. The connector is actively produced and maintains full inventory availability with 965 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate alternative connector specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761553604 is determined by the following critical parameters:

Position Count & Matrix Configuration: The substitute part must maintain 192 total positions in a 12×16 matrix configuration to ensure PCB layout compatibility and connector footprint alignment.

Connector Type & Termination: Both the main part and substitute must be header-style male pin connectors with press-fit termination to ensure mechanical and electrical compatibility with mating receptacles and PCB assembly processes.

Mounting Method: Through-hole mounting is required for both parts to maintain assembly compatibility with existing PCB designs.

Contact Finish & Electrical Properties: Gold plating at 30.0µin thickness and UL94 V-0 flammability rating are baseline requirements for electrical performance and safety compliance.

Environmental & Compliance Standards: RoHS3 compliance and MSL 1 rating ensure regulatory alignment and handling compatibility.

The TE Connectivity AMP Connectors part 1934316-1 qualifies as a substitute based on these core parameters, though pitch spacing and voltage rating differ from the main part specification.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0761553604 and TE Connectivity 1934316-1 maintain active product status with full manufacturing support and regulatory compliance. Selection between these parts depends on application-specific requirements not addressed by substitution criteria alone.

The Molex 0761553604 operates within a -55°C to 85°C temperature range with a 30V voltage rating and 0.053" pitch spacing. The TE Connectivity 1934316-1 extends the operating temperature range to -65°C to 90°C and provides a higher 250V voltage rating, though with a larger 0.075" pitch spacing that requires PCB layout modification.

Both connectors meet UL94 V-0 flammability requirements, maintain RoHS compliance, and feature identical contact finish specifications. Moisture sensitivity level 1 (unlimited) applies to both parts, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1934316-1 be used as a direct drop-in replacement for the Molex 0761553604?

A: No. While both connectors maintain 192 positions in a 12×16 matrix configuration, the pitch spacing differs (0.053" versus 0.075"). This difference requires PCB layout modification and cannot be accommodated through connector selection alone. Direct substitution is not possible without redesign.

Q: What are the key compatibility factors when selecting between these two connectors?

A: Position count, matrix configuration, connector type, mounting method, and termination style are the primary compatibility factors. Both parts satisfy these criteria. Secondary factors including pitch spacing, voltage rating, and operating temperature range must be evaluated against specific application requirements.

Q: Are both connectors RoHS compliant?

A: Yes. The Molex 0761553604 is ROHS3 compliant, and the TE Connectivity 1934316-1 is RoHS compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special environmental controls.

Q: How do the voltage ratings compare?

A: The Molex 0761553604 is rated for 30V operation, while the TE Connectivity 1934316-1 is rated for 250V. The higher voltage rating of the TE part provides additional margin for applications requiring elevated voltage tolerance.

Q: What is the operating temperature difference between these parts?

A: The Molex 0761553604 operates from -55°C to 85°C. The TE Connectivity 1934316-1 extends this range to -65°C to 90°C, providing wider temperature coverage for extreme environment applications.
