Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761503116 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Receptacle, Female Sockets
• Number of positions: 288
• Mounting configuration: Board Edge, Through Hole, Right Angle
• Termination method: Press-Fit
• Contact finish: Gold plating

Secondary Compatibility Parameters:

• Operating temperature range: -55°C ~ 85°C (minimum requirement)
• Voltage rating: 30V or higher
• Material flammability: UL94 V-0
• Connector style: Impact configuration with guide

The TE Connectivity AMP Connectors part 1-2007742-1 meets these core substitution criteria. However, the pitch specification differs (0.075" vs. 0.053"), which represents a mechanical incompatibility that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-2007742-1 provides functional equivalence to the obsolete Molex 0761503116 across most critical parameters, including connector type, position count, mounting configuration, termination method, and environmental ratings.

The primary technical distinction is the pitch specification: the TE part operates at 0.075" (1.91mm) versus the Molex part at 0.053" (1.35mm). This difference affects board layout, hole spacing, and mating interface geometry. Selection between these parts depends on whether the application PCB is designed for the original 0.053" pitch or can accommodate the 0.075" pitch specification.

The TE Connectivity part holds active product status, ensuring ongoing availability and supply chain support. Both parts maintain identical compliance certifications (UL94 V-0, RoHS, REACH status), operating temperature ranges, and voltage ratings, supporting direct substitution in applications where pitch compatibility is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-2007742-1 directly replace the Molex 0761503116 without PCB modification?

A: Direct replacement without modification is not possible due to pitch incompatibility. The Molex part uses 0.053" pitch while the TE part uses 0.075" pitch. PCB hole spacing and mounting hole locations must be verified for compatibility. If the PCB is designed for the original 0.053" pitch, the TE part cannot be installed without board redesign.

Q: Are there electrical performance differences between these connectors?

A: Both connectors share identical voltage ratings (30V), operating temperature ranges (-55°C ~ 85°C), contact finish specifications (Gold, 30.0µin), and flammability ratings (UL94 V-0). The TE part specifies a current rating of 0.75A per contact, while the Molex part does not provide this specification in the available data.

Q: What is the significance of the product status difference?

A: The Molex 0761503116 is classified as obsolete, indicating discontinued manufacturing and limited availability. The TE Connectivity 1-2007742-1 maintains active status, ensuring continued production, supply chain availability, and technical support for new designs or legacy system maintenance.

Q: Do both connectors meet the same compliance standards?

A: Both connectors meet UL94 V-0 flammability requirements and RoHS compliance standards. The Molex part is ROHS3 compliant while the TE part is RoHS compliant. Both are EAR99 classified and share identical HTSUS codes (8536.69.4040), supporting equivalent regulatory treatment.

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

A: The Molex part specifies 96 differential pairs in its contact layout. The TE part specifies 192 signal contacts and 96 ground contacts. This difference reflects different internal pin assignment strategies while maintaining the same 288-position total count.
