Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0761651813 are identified based on the following critical parameters that determine functional equivalence:

• Number of Positions: 72 (exact match required)
• Connector Type: Header or Plug configuration with male pins
• Mounting Type: Through Hole (PCB mounting compatibility)
• Termination Method: Press-Fit (assembly process compatibility)
• Contact Finish: Gold (electrical performance and corrosion resistance)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Product Status: Active (ongoing availability)

The substitute parts listed below maintain these core parameters while operating within acceptable electrical and mechanical tolerances for backplane connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance equivalent to the Molex 0761651813.

TE Connectivity 1934300-1 (Header configuration) provides direct functional substitution with identical connector type classification. This part operates across an extended temperature range (-65°C ~ 90°C) and supports higher voltage ratings (250V) compared to the original specification (30V).

TE Connectivity 1934302-1 (Plug configuration) offers substitution for applications requiring plug-type connectors rather than headers. This part shares identical electrical and thermal specifications with the 1934300-1 and maintains compatibility with press-fit assembly processes.

Both substitute parts feature pitch spacing of 0.075" (1.90mm), which differs from the original 0.053" (1.35mm) pitch. PCB layout modifications are required when implementing these substitutes.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1934300-1 and 1934302-1 be used interchangeably with the Molex 0761651813?

A: Both parts maintain the same 72-position count, through-hole mounting, press-fit termination, and gold contact finish. However, the pitch difference (0.075" versus 0.053") requires PCB redesign. The connector type difference (header versus plug) determines specific application compatibility.

Q: What is the impact of pitch spacing differences between these parts?

A: Pitch spacing determines the physical distance between connector pins and the corresponding PCB pad layout. The Molex 0761651813 uses 0.053" (1.35mm) pitch, while both TE Connectivity substitutes use 0.075" (1.90mm) pitch. Direct PCB substitution is not possible without layout modification.

Q: Are the operating temperature ranges compatible?

A: The Molex 0761651813 operates from -55°C to 85°C. Both TE Connectivity substitutes operate from -65°C to 90°C, providing extended temperature capability. Applications within the original temperature range remain fully compatible.

Q: Do voltage rating differences affect substitution decisions?

A: The Molex 0761651813 is rated for 30V, while both TE Connectivity substitutes are rated for 250V. The higher voltage rating of substitute parts provides additional safety margin and does not restrict substitution in applications operating at or below 30V.

Q: What packaging differences exist between these parts?

A: The Molex 0761651813 is supplied in Tray packaging. TE Connectivity 1934300-1 and 1934302-1 are supplied in Tube packaging. Packaging format does not affect electrical or mechanical compatibility but may impact handling and storage procedures.
