Substitution basis: Identical electrical and mechanical specifications with only packaging variation (Tray vs. standard packaging)
Key matching parameters: 72 positions, 0.053" pitch, 9×8 matrix, through-hole mounting, press-fit termination, gold contact finish, 30V voltage rating, -55°C to 85°C operating range, UL94 V-0 flammability, ROHS3 compliance

Category 2: Cross-Manufacturer TE Connectivity Alternatives

Part numbers 1934300-1, 1934301-1, and 1934302-1 are TE Connectivity AMP Connectors from the Z-PACK TinMan series
Substitution basis: Matching 72-position count, through-hole mounting, press-fit termination, gold contact finish, UL94 V-0 flammability, and ROHS3 compliance
Differences: Larger 0.075" pitch, different matrix configuration (9×3 or 9×8), higher voltage rating (250V), extended temperature range (-65°C to 90°C), and higher current rating (0.5A)
Note: Part 1934302-1 is a plug connector type rather than header type

Engineering Selection Recommendations

For Direct Replacement (Preferred): The Molex 0761651838 is the recommended substitute for the obsolete 0761650838. Both parts maintain identical electrical and mechanical specifications within the Impact 76165 series. The 0761651838 is currently in active production status with higher inventory availability (1004 units), ensuring supply chain continuity. This substitution requires no design modifications and maintains full compatibility with existing PCB layouts and mating connectors.

For Cross-Manufacturer Substitution: TE Connectivity AMP Connector alternatives (1934300-1, 1934301-1, 1934302-1) are suitable only when design flexibility permits accommodation of different pitch spacing (0.075" vs. 0.053") and matrix configurations. These parts offer enhanced electrical performance with higher voltage ratings (250V vs. 30V) and extended operating temperature range (-65°C to 90°C vs. -55°C to 85°C). All alternatives maintain ROHS3 compliance and UL94 V-0 flammability certification.

Connector Type Consideration: Part 1934302-1 is a plug connector type rather than a header type. This part is suitable only for applications requiring a mating plug configuration and is not interchangeable with header-type applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761651838 be used as a direct replacement for the 0761650838? A: Yes. Both parts are from the Molex Impact 76165 series and share identical electrical and mechanical specifications. The only difference is packaging format (Tray vs. standard). No design changes are required.

Q: What are the key differences between the Molex Impact series and TE Connectivity Z-PACK TinMan alternatives? A: The primary differences are pitch spacing (0.053" vs. 0.075"), voltage rating (30V vs. 250V), operating temperature range (-55°C to 85°C vs. -65°C to 90°C), and current rating (not specified vs. 0.5A). Matrix configurations also differ for some models. These differences may require PCB layout modifications.

Q: Is the TE Connectivity 1934302-1 compatible with applications designed for the Molex 0761650838? A: No. The 1934302-1 is a plug connector type, while the Molex 0761650838 is a header type. These connector types are not interchangeable and serve different mating functions.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The Molex 0761651838 and all TE Connectivity alternatives (1934300-1, 1934301-1, 1934302-1) are ROHS3 compliant with UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating.

Q: What is the inventory status of available substitutes? A: Molex 0761651838 has 1004 units in stock. TE Connectivity alternatives have varying availability: 1934300-1 (732 units), 1934301-1 (855 units), and 1934302-1 (3458 units).

Q: Can the TE Connectivity parts be used in existing designs without PCB modifications? A: No. The TE Connectivity alternatives have different pitch spacing (0.075" vs. 0.053") and different matrix configurations, requiring PCB layout modifications to accommodate the new connector footprint.
