Molex 0764559607 96-Position Backplane Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0764559607 is a 96-position backplane connector header designed for through-hole PCB mounting. This male pin header features an Impact connector style with guide right configuration, supporting 32 differential pairs across a 6×16 position matrix. The component is actively manufactured and widely used in high-density interconnect applications requiring reliable press-fit termination and gold-plated contacts.

Identifying equivalent and substitute parts is necessary when addressing supply chain constraints, lead time requirements, or design flexibility needs while maintaining electrical and mechanical compatibility with existing PCB layouts and system specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0764559607 is determined by strict alignment of the following critical parameters:

• Connector Type & Style: Must be Header, Male Pins with Impact, Guide Right configuration
• Position Count & Matrix: Exactly 96 positions arranged in 6 rows × 16 columns
• Mounting & Termination: Through-hole PCB mounting with press-fit termination
• Contact Specifications: Gold plating at 30.0µin thickness minimum
• Environmental Ratings: Operating temperature -55°C to 85°C, voltage rating 30V or higher
• Compliance: UL94 V-0 flammability, RoHS compliance, MSL 1

The TE Connectivity AMP Connectors part number 2057743-2 meets all substitution criteria. Both components share identical position counts, matrix configurations, mounting methods, and environmental specifications. The TE part provides additional specification detail (0.075" pitch, 0.75A current rating, 64 signal + 32 ground layout) while maintaining full mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0764559607 and TE Connectivity 2057743-2 are active production components with full RoHS compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Molex 0764559607: Choose when the original design specifies 32 differential pair configuration and when Molex supply chain availability is preferred.

TE Connectivity 2057743-2: Choose when 64 signal + 32 ground contact layout aligns with system requirements, when TE Connectivity supply chain offers better lead times, or when the specified 0.75A current rating and 0.075" pitch are compatible with PCB design parameters.

Both components support identical operating temperature ranges (-55°C to 85°C), voltage ratings (30V), and moisture sensitivity levels (MSL 1). PCB footprint compatibility must be verified against the specific pitch and contact layout requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2057743-2 be used as a direct replacement for the Molex 0764559607 on existing PCBs?

A: Mechanical and electrical compatibility is confirmed for both 96-position, 6×16 matrix through-hole headers with press-fit termination. However, the contact layout differs (32 differential pairs vs. 64 signal + 32 ground). PCB footprint compatibility depends on pitch alignment and contact arrangement. Physical verification against the target PCB design is required before implementation.

Q: What is the significance of the contact layout difference between these parts?

A: The Molex part specifies 32 differential pairs, while the TE part specifies 64 signal contacts and 32 ground contacts. This difference affects how signals and ground planes are distributed across the connector matrix. The appropriate choice depends on the system's signal integrity and grounding architecture requirements.

Q: Are both parts suitable for high-reliability applications?

A: Both components meet UL94 V-0 flammability requirements and RoHS compliance standards. Both operate across -55°C to 85°C temperature ranges with MSL 1 moisture sensitivity ratings. Suitability for specific high-reliability applications depends on additional system-level requirements not specified in component datasheets.

Q: What should be verified before switching between these two parts?

A: Verify PCB footprint compatibility including pitch spacing (0.075" for TE part), contact layout arrangement, mounting hole positions, and guide pin placement. Confirm that the contact configuration (differential pairs vs. signal/ground split) aligns with system signal routing and grounding requirements. Validate that both parts are available in the required packaging and lead time windows.

Q: Is there a current rating difference that affects component selection?

A: The TE Connectivity part specifies 0.75A current rating. The Molex part does not provide a current rating specification. If the application requires explicit current rating documentation, the TE part provides this parameter. System-level current requirements should be evaluated against the specified 0.75A rating for the TE component.
