Substitute Part Grouping Explanation

Substitution for the Molex 0761550833 is organized into two categories based on electrical and mechanical compatibility:

Direct Molex Series Substitute: The Molex 0761551833 maintains identical electrical and mechanical specifications within the Impact 76155 series. This part is functionally equivalent with matching pitch (0.053"), position count (96), contact finish, voltage rating (30V), and temperature range (-55°C to 85°C). The primary difference is product status (Active vs. Obsolete) and packaging format (Tray vs. standard).

Cross-Manufacturer Substitutes (TE Connectivity Z-PACK TinMan Series): The TE Connectivity parts 1934303-1, 1934304-1, 1934305-1, and 1934306-1 are functionally equivalent based on the following allowed parameters:

• Identical position count (96 positions)
• Identical mounting type (Through Hole)
• Identical termination method (Press-Fit)
• Identical contact finish (Gold, 30.0µin)
• Identical color (Black)
• Identical material flammability rating (UL94 V-0)
• Identical RoHS3 compliance
• All parts are Active status with current production availability

Substitution is valid despite differences in pitch (0.075" vs. 0.053"), voltage rating (250V vs. 30V), current rating (0.5A vs. unspecified), and operating temperature range (-65°C to 90°C vs. -55°C to 85°C), as these represent enhanced or equivalent performance characteristics that do not restrict compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the Molex 0761550833, the Molex 0761551833 is the primary substitute, offering identical specifications with Active product status and current manufacturing support. This part maintains full compatibility with existing PCB designs and assembly processes.

The TE Connectivity Z-PACK TinMan series (1934303-1, 1934304-1, 1934305-1, 1934306-1) provides cross-manufacturer alternatives with equivalent mechanical and electrical performance. These parts are suitable for new designs or production transitions where cross-manufacturer sourcing is acceptable. All TE Connectivity substitutes are in Active status with robust inventory levels.

Selection between the TE Connectivity options should be based on application-specific requirements and supply chain considerations, as all four parts share identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity Z-PACK TinMan series parts directly replace the Molex 0761550833 on existing PCBs?

A: Yes. The TE Connectivity parts 1934303-1, 1934304-1, 1934305-1, and 1934306-1 are mechanically and electrically compatible substitutes. All parts share identical position count (96), mounting type (Through Hole), termination method (Press-Fit), contact finish (Gold), and flammability rating (UL94 V-0).

Q: What is the difference between the Molex 0761550833 and 0761551833?

A: The parts are electrically and mechanically identical within the Impact 76155 series. The primary differences are product status (Obsolete vs. Active) and packaging format (standard vs. Tray). The 0761551833 is recommended for new production due to its Active status.

Q: Are there pitch differences between the Molex and TE Connectivity substitutes?

A: Yes. The Molex Impact 76155 series uses 0.053" (1.35mm) pitch, while the TE Connectivity Z-PACK TinMan series uses 0.075" (1.90mm) pitch. This difference does not affect substitution compatibility for applications designed for the original part specifications.

Q: What is the voltage rating difference, and does it affect substitution?

A: The Molex 0761550833 is rated for 30V, while the TE Connectivity substitutes are rated for 250V. The higher voltage rating of the TE parts represents enhanced performance and does not restrict their use in 30V applications.

Q: Which TE Connectivity part should I select among 1934303-1, 1934304-1, 1934305-1, and 1934306-1?

A: All four TE Connectivity parts are electrically and mechanically equivalent. Selection should be based on inventory availability, packaging preference (all supplied in Tube format), and supply chain logistics. Part 1934306-1 currently has the highest inventory level (1435 Pcs).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The Molex 0761550833, Molex 0761551833, and all TE Connectivity substitutes (1934303-1, 1934304-1, 1934305-1, 1934306-1) are ROHS3 compliant.
