Molex 0761554608 Impact 192-Position Backplane Connector Header

Part Overview

The Molex 0761554608 is a 192-position backplane connector header featuring male pins configured for through-hole mounting with press-fit termination. This connector is part of the Impact 76155 series and is designed for high-density interconnect applications requiring 64 differential pairs across a 12×16 position matrix.

The 0761554608 is classified as obsolete. Equivalent active production alternatives are available that maintain identical electrical and mechanical specifications, making direct substitution feasible for new designs and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0761554608 is based on strict equivalence across all electrical and mechanical parameters. The substitute parts maintain identical specifications in the following critical areas:

• Connector Type & Style: Header with male pins, Impact series, Guide Right configuration
• Position Count & Matrix: 192 positions in 12×16 arrangement with 64 differential pairs
• Pitch & Spacing: 0.053" (1.35mm) pitch maintained across all alternatives
• Mounting & Termination: Through-hole mounting with press-fit termination
• Contact Properties: Gold finish at 30.0µin thickness
• Electrical Ratings: 30V voltage rating and -55°C to 85°C operating range
• Compliance: ROHS3 compliant, UL94 V-0 flammability rating, MSL 1

The substitute parts differ only in product status (active vs. obsolete) and packaging configuration (tray packaging for active alternatives).

Parameter Comparison

Engineering Selection Recommendations

Both 0761555608 and 0761559608 are direct functional equivalents to the obsolete 0761554608. Selection between the two active alternatives should be based on inventory availability and packaging requirements.

The 0761555608 provides 694 units in current stock, while the 0761559608 provides 1053 units. Both are classified as active production parts with full ROHS3 compliance and REACH unaffected status, ensuring long-term supply chain viability for new designs and production runs.

For applications currently using the 0761554608, either substitute part can be implemented without design modification, as all electrical, mechanical, and environmental specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can the 0761555608 or 0761559608 be used as direct replacements for the 0761554608?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, contact configuration, voltage rating, temperature range, and compliance certifications.

Q: What is the difference between the three part numbers?

A: The 0761554608 is obsolete. The 0761555608 and 0761559608 are active production equivalents with identical specifications. The only differences are product status and packaging format (tray packaging for active parts).

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. The parts are mechanically and electrically interchangeable. PCB footprints, mounting hole patterns, and contact spacing are identical across all three part numbers.

Q: Which substitute part should be selected for new designs?

A: Either 0761555608 or 0761559608 is suitable for new designs. Selection can be based on inventory availability and packaging preferences. The 0761559608 currently has higher stock levels (1053 units vs. 694 units).

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.
