Substitution Categories:
Category 1: Direct Molex Series Equivalent
- Part 0761551604 maintains identical electrical and mechanical specifications with the same Impact 76155 series design. The primary difference is packaging (Tray vs. standard) and active product status.
Category 2: Cross-Manufacturer Alternatives (TE Connectivity AMP Connectors)
- Parts 1934315-1, 1934316-1, 1934317-1, and 1934318-1 are TE Connectivity Z-PACK TinMan series connectors that meet the core 192-position, 12x16 configuration with through-hole press-fit mounting. These parts differ in pitch specification (0.075" vs. 0.053"), voltage rating (250V vs. 30V), and current rating (0.5A vs. unspecified), but maintain mechanical compatibility and compliance requirements.

Engineering Selection Recommendations
For Direct Replacement (Same Series): Part 0761551604 is the recommended direct equivalent. It maintains identical electrical and mechanical specifications within the Molex Impact 76155 series and carries active product status, ensuring long-term availability and supply chain continuity.
For Cross-Manufacturer Substitution: TE Connectivity AMP Connectors parts 1934315-1, 1934316-1, 1934317-1, and 1934318-1 are functionally compatible alternatives. These parts maintain the 192-position configuration, 12x16 row/column layout, through-hole press-fit mounting, and UL94 V-0 flammability rating. All substitute parts carry active product status and ROHS3 or RoHS compliance certification.
The TE Connectivity alternatives provide enhanced electrical performance with 250V voltage rating and 0.5A current rating compared to the original 30V specification. The pitch difference (0.075" vs. 0.053") requires PCB layout verification to confirm mechanical compatibility with existing board designs.
Frequently Asked Questions (FAQ)
Q: Can 0761551604 be used as a direct replacement for 0761550604? A: Yes. Part 0761551604 is a direct equivalent within the Molex Impact 76155 series. It maintains identical position count (192), pitch (0.053"), row/column configuration (12x16), mounting type (through-hole), termination method (press-fit), contact finish (gold), and compliance ratings. The primary difference is packaging format (Tray) and active product status.
Q: What are the key differences between Molex and TE Connectivity substitutes? A: The TE Connectivity Z-PACK TinMan series (1934315-1, 1934316-1, 1934317-1, 1934318-1) maintains the 192-position, 12x16 configuration and through-hole press-fit mounting. However, they differ in pitch specification (0.075" vs. 0.053"), voltage rating (250V vs. 30V), and current rating (0.5A vs. unspecified). These differences require PCB layout verification and electrical circuit analysis before implementation.
Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts meet RoHS compliance requirements. The main part and 0761551604 carry ROHS3 certification. TE Connectivity parts 1934315-1, 1934317-1, and 1934318-1 carry ROHS3 certification, while 1934316-1 carries RoHS certification.
Q: What packaging options are available for substitutes? A: Molex 0761551604 is supplied in Tray packaging. TE Connectivity alternatives are available in Tube (1934315-1, 1934317-1, 1934318-1) and Bulk (1934316-1) packaging formats.
Q: Do all parts meet the same temperature operating range? A: The original part operates from -55°C to 85°C. TE Connectivity substitutes operate from -65°C to 90°C, providing an extended temperature range suitable for broader environmental applications.
Q: Is PCB layout modification required when using TE Connectivity substitutes? A: PCB layout verification is required due to the pitch difference (0.075" for TE Connectivity vs. 0.053" for Molex). The different pitch spacing may require footprint adjustment on the PCB. Mechanical compatibility with existing connector receptacles must be confirmed before design implementation.
