Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761505116 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
• Contact finish: Gold plating
• Flammability rating: UL94 V-0 or equivalent
• Operating temperature range: -55°C ~ 85°C minimum
• Voltage rating: 30V or higher

Secondary Considerations:

• Pitch tolerance: Connector pitch affects PCB layout compatibility
• Termination method: Press-Fit termination required
• Series compatibility: Impact series styling

The TE Connectivity AMP Connectors part 1-2007743-1 meets the primary functional requirements as a 288-position receptacle with board edge mounting and right-angle configuration. However, the pitch specification differs (0.075" vs. 0.053"), which represents a material design change requiring PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-2007743-1 is an active product with current manufacturing support, whereas the Molex 0761505116 is obsolete. Both connectors maintain identical compliance certifications (UL94 V-0, RoHS compliance) and equivalent operating temperature ranges (-55°C ~ 85°C).

The primary engineering consideration is pitch specification. The TE Connectivity part operates at 0.075" (1.91mm) pitch compared to the Molex part's 0.053" (1.35mm) pitch. This difference directly impacts PCB footprint design and cannot be accommodated through connector selection alone; PCB layout modification is required for physical compatibility.

The TE Connectivity part includes a board guide feature and specifies current rating (0.75A) and contact layout (192 Signal, 96 Ground), providing additional design clarity for high-density backplane applications. Selection of this substitute requires confirmation that the PCB design accommodates the larger pitch spacing.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-2007743-1 be used as a direct replacement for the Molex 0761505116?

A: Direct mechanical and electrical substitution is not possible due to pitch specification differences (0.075" vs. 0.053"). PCB layout modification is required. Both connectors share identical electrical ratings, flammability compliance, and operating temperature ranges.

Q: What is the significance of the pitch difference between these connectors?

A: Pitch defines the center-to-center spacing between connector positions. The 0.075" pitch of the TE Connectivity part requires wider PCB trace spacing and larger board footprint compared to the 0.053" pitch Molex design. Existing PCB layouts designed for the Molex connector cannot accommodate the TE Connectivity connector without redesign.

Q: Are both connectors RoHS compliant?

A: Yes. The Molex 0761505116 is ROHS3 Compliant, and the TE Connectivity 1-2007743-1 is RoHS Compliant. Both meet current environmental compliance requirements.

Q: What is the product status difference, and why does it matter?

A: The Molex part is classified as obsolete, indicating discontinued manufacturing and limited availability. The TE Connectivity part is active, ensuring ongoing supply and manufacturing support. For new designs or long-term system support, the active TE Connectivity part is the preferred selection.

Q: Do both connectors support the same voltage and current specifications?

A: Both connectors are rated for 30V. The TE Connectivity part specifies 0.75A current rating per contact. The Molex part does not provide current rating specification in the available data. Electrical performance is equivalent for standard backplane applications within the 30V rating.

Q: What does "board guide" mean on the TE Connectivity connector?

A: Board guide refers to a mechanical feature that aids in connector alignment during assembly. This feature improves insertion accuracy and reduces assembly errors in high-density backplane configurations.
