Substitute Part Grouping Explanation

Substitution for the Molex 0761650813 is determined by the following critical parameters: 72-position count, through-hole mounting, press-fit termination, gold contact finish, and PCB header configuration. The substitute parts are grouped into two categories based on electrical and mechanical compatibility:

Category 1: Direct Molex Series Substitute The Molex 0761651813 maintains identical electrical and mechanical specifications as the main part, differing only in product status (Active vs. Obsolete) and packaging format (Tray vs. standard). This part operates within the same Impact 76165 series and preserves all critical parameters.

Category 2: Cross-Manufacturer Substitutes (TE Connectivity) The TE Connectivity parts (1934300-1, 1934301-1, 1934302-1) provide functional alternatives with modified pitch (0.075" vs. 0.053"), different row/column configurations, and enhanced electrical ratings. These substitutes maintain the 72-position count, through-hole mounting, press-fit termination, and gold contact finish, but operate at higher voltage (250V vs. 30V) and current (0.5A) ratings with extended temperature range (-65°C ~ 90°C).

Engineering Selection Recommendations

For Direct Replacement (Preferred): The Molex 0761651813 is the primary substitute for the obsolete 0761650813. Both parts maintain identical electrical and mechanical specifications within the Impact 76165 series. The 0761651813 is currently in active production status with 974 units in stock, ensuring supply chain continuity. This part requires no design modifications and provides the most straightforward transition path.

For Cross-Manufacturer Substitution: TE Connectivity parts (1934300-1, 1934301-1, 1934302-1) are suitable when design flexibility permits accommodation of modified pitch spacing (0.075" vs. 0.053"). These alternatives offer enhanced electrical performance with 250V voltage rating and 0.5A current capability, along with extended operating temperature range (-65°C ~ 90°C). All TE Connectivity substitutes maintain ROHS3 compliance and UL94 V-0 flammability rating.

The TE 1934302-1 differs as a plug connector rather than header configuration; selection depends on mating interface requirements. The TE 1934300-1 features a 9×3 column arrangement, while TE 1934301-1 maintains the 9×8 configuration matching the original part's physical layout.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761651813 be used as a direct replacement for the 0761650813? A: Yes. Both parts share identical specifications for connector type, position count, pitch, row/column configuration, mounting method, termination style, contact finish, operating temperature, voltage rating, and flammability rating. The only differences are product status and packaging format.

Q: What are the key differences between Molex and TE Connectivity substitutes? A: The primary differences are pitch spacing (0.053" Molex vs. 0.075" TE), voltage rating (30V vs. 250V), current rating (unspecified vs. 0.5A), and operating temperature range (-55°C~85°C vs. -65°C~90°C). TE parts offer higher electrical performance but require PCB layout modifications due to increased pitch.

Q: Can TE Connectivity parts be used in existing PCB designs? A: TE Connectivity substitutes require PCB redesign due to pitch modification from 0.053" to 0.075". The increased spacing affects hole placement and trace routing. Mechanical compatibility with existing mating connectors must be verified before implementation.

Q: Why does TE 1934302-1 differ from other TE substitutes? A: The 1934302-1 is a plug connector type, whereas the main part and other substitutes are header connectors. Plug connectors are designed to mate with header receptacles. Selection depends on whether the application requires a header or plug interface.

Q: Are all substitute parts RoHS3 compliant? A: Yes. The Molex 0761651813 and all TE Connectivity substitutes (1934300-1, 1934301-1, 1934302-1) are ROHS3 compliant with UL94 V-0 flammability rating, meeting current environmental and safety standards.

Q: What is the inventory status for substitute parts? A: Molex 0761651813 has 974 units in stock. TE Connectivity 1934300-1 has 732 units, 1934301-1 has 855 units, and 1934302-1 has 3458 units available.
