Molex 0761552604 192-Position Backplane Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0761552604 is a 192-position backplane connector header designed for through-hole PCB mounting. This component features male pins with Impact connector styling and left-side guide configuration. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and new design implementations.

The necessity to identify substitutes stems from the obsolete product status, which may result in limited availability and extended lead times. Active equivalent parts ensure design continuity and supply chain reliability.

Engineering Selection Recommendations

Molex 0761553604 (Direct Substitute)

The Molex 0761553604 is the primary equivalent for the obsolete 0761552604. Both components share identical electrical and mechanical specifications, including pitch (0.053"), position count (192), row/column configuration (12×16), and operating parameters. The 0761553604 maintains active product status with established supply chain availability. This part is suitable for direct replacement in existing designs without PCB or connector interface modifications.

TE Connectivity 1934316-1 (MFR Recommended Alternative)

The TE Connectivity 1934316-1 serves as a manufacturer-recommended alternative when Molex equivalents are unavailable. This component maintains the 192-position, 12×16 configuration and through-hole press-fit termination required for backplane applications. The pitch specification differs at 0.075" (1.90mm) compared to the original 0.053" (1.35mm), requiring PCB layout verification and potential redesign of the connector footprint. The TE part offers extended operating temperature range (-65°C ~ 90°C) and higher voltage rating (250V), providing enhanced performance margins. Active product status ensures reliable supply availability.

Selection between these substitutes depends on design constraints: the Molex 0761553604 enables direct replacement, while the TE Connectivity 1934316-1 requires footprint validation but offers superior electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761553604 be used as a direct replacement for the 0761552604?

A: Yes. Both components are identical in electrical and mechanical specifications. The 0761553604 is the active production equivalent and requires no design modifications.

Q: What is the primary difference between the Molex 0761553604 and TE Connectivity 1934316-1?

A: The connector pitch differs: Molex uses 0.053" (1.35mm) while TE Connectivity uses 0.075" (1.90mm). This pitch difference requires PCB footprint verification and potential redesign. The TE part also provides higher voltage rating (250V vs. 30V) and extended temperature range.

Q: Does the pitch difference of the TE Connectivity part affect compatibility?

A: Yes. The pitch difference means the connector footprint on the PCB must be modified to accommodate the TE Connectivity 1934316-1. Direct physical substitution without PCB redesign is not possible.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0761553604 is ROHS3 Compliant, and the TE Connectivity 1934316-1 is RoHS Compliant. Both meet environmental compliance requirements.

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

A: All listed parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Which substitute should be selected for new designs?

A: The Molex 0761553604 is recommended for new designs requiring direct compatibility with existing specifications. The TE Connectivity 1934316-1 is suitable when enhanced electrical ratings and extended temperature range are beneficial and PCB redesign is feasible.
