Substitute Categories:

Category 1: Direct Molex Series Equivalent

Part 0761551818: Identical electrical and mechanical specifications to the main part. Differs only in packaging (Tray vs. standard) and product status (Active vs. Obsolete). This is the direct replacement within the Molex Impact 76155 series.

Category 2: TE Connectivity Cross-Functional Substitutes

Parts 1934303-1, 1934304-1, 1934305-1, 1934306-1: These TE Connectivity Z-PACK TinMan series connectors share the same 96-position configuration, male pin header type, through-hole mounting, press-fit termination, 12×8 layout, gold finish, black color, and UL94 V-0 rating. All are ROHS3 compliant and active products. These parts differ in pitch specification (0.075" vs. 0.053"), operating temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C), voltage rating (250V vs. 30V), and current rating (0.5A specified vs. unspecified for main part).

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select Molex 0761551818 when the original Impact 76155 series specification must be maintained. This part is the active equivalent with identical electrical and mechanical parameters, ROHS3 compliance, and unlimited moisture sensitivity rating. Product status is active with current inventory availability.

For Cross-Manufacturer Substitution: TE Connectivity parts 1934303-1, 1934304-1, 1934305-1, and 1934306-1 are suitable substitutes when PCB layout and mechanical envelope accommodate the larger 0.075" (1.90mm) pitch. These parts provide enhanced electrical performance with 250V voltage rating and 0.5A current rating specification. All four parts maintain UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 rating. Operating temperature range extends to -65°C ~ 90°C, providing broader environmental coverage. All TE Connectivity substitutes are active products with current inventory.

Selection Criteria:

Use 0761551818 for direct form-fit-function replacement within existing designs
Use TE Connectivity parts when design allows pitch accommodation and enhanced electrical specifications are beneficial
All substitute options maintain required compliance certifications and flammability ratings
All substitute options are active products with established supply chains

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity parts directly replace the Molex 0761550818 without PCB modification? A: No. The TE Connectivity Z-PACK TinMan series uses 0.075" (1.90mm) pitch versus the Molex Impact series 0.053" (1.35mm) pitch. PCB layout and hole spacing must be modified to accommodate the larger pitch. The Molex 0761551818 provides direct replacement without PCB changes.

Q: What is the primary difference between Molex 0761550818 and 0761551818? A: Both parts are electrically and mechanically identical. The main difference is product status: 0761550818 is obsolete while 0761551818 is active. Packaging differs (standard vs. Tray), but specifications are equivalent.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The main part 0761550818 and all substitute parts (0761551818, 1934303-1, 1934304-1, 1934305-1, 1934306-1) are ROHS3 compliant.

Q: Do the TE Connectivity substitutes offer any performance advantages? A: Yes. TE Connectivity parts specify 0.5A current rating and 250V voltage rating compared to the Molex 30V rating. Operating temperature range extends to -65°C ~ 90°C versus -55°C ~ 85°C for the Molex parts. These represent enhanced electrical specifications suitable for demanding applications.

Q: What is the moisture sensitivity level for all parts? A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there differences in contact finish between substitute parts? A: No. All parts feature gold contact finish with 30.0µin (0.76µm) thickness specification.

Q: Which substitute should be selected for new designs? A: For new designs, Molex 0761551818 is recommended as the primary choice due to active product status and direct compatibility. TE Connectivity parts are suitable alternatives when the 0.075" pitch accommodates the PCB layout and enhanced electrical specifications are required.
