Substitution Categories:

Direct Molex Substitute: Part 0761551827 maintains identical electrical and mechanical specifications as the original 0761550827, differing only in packaging (Tray vs. standard). This part is active and fully interchangeable.

Cross-Manufacturer Substitutes: TE Connectivity AMP Connectors parts 1934303-1, 1934304-1, 1934305-1, and 1934306-1 (Z-PACK TinMan series) provide functional equivalence with the following parameter variations:

Pitch: 0.075" (1.90mm) instead of 0.053" (1.35mm)
Voltage Rating: 250V instead of 30V
Current Rating: 0.5A (specified, vs. unspecified for Molex)
Operating Temperature: -65°C to 90°C (extended range)
Connector Style: High Speed instead of Impact

These TE Connectivity parts maintain the same 96-position count, through-hole mounting, press-fit termination, 12×8 configuration, gold finish, and UL94 V-0 rating.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): Select Molex 0761551827. This part maintains all electrical and mechanical parameters of the original 0761550827 while offering active product status and ongoing manufacturer support. The only difference is packaging format (Tray), which does not affect functional performance.

For Cross-Manufacturer Substitution (TE Connectivity Z-PACK TinMan Series): The TE Connectivity parts 1934303-1, 1934304-1, 1934305-1, and 1934306-1 are suitable when:

PCB layout accommodates the larger 0.075" (1.90mm) pitch spacing
Application voltage requirements are within the 250V rating
Extended operating temperature range (-65°C to 90°C) is beneficial
Higher current capacity (0.5A per contact) is required

All substitute parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and active product status, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0761551827 as a direct replacement for 0761550827? A: Yes. The 0761551827 is electrically and mechanically identical to the 0761550827. The only difference is packaging (Tray vs. standard). Both parts feature 96 positions, 0.053" pitch, through-hole press-fit termination, and identical electrical ratings.

Q: What is the main difference between the Molex Impact series and TE Connectivity Z-PACK TinMan series? A: The primary difference is connector pitch: Molex Impact uses 0.053" (1.35mm) while TE Z-PACK TinMan uses 0.075" (1.90mm). This affects PCB layout spacing. TE parts also offer higher voltage (250V vs. 30V) and specified current ratings (0.5A).

Q: Can I substitute a TE Connectivity part for the Molex 0761550827 on an existing PCB? A: No, not without PCB redesign. The TE Connectivity parts use 0.075" pitch versus the Molex 0.053" pitch. The larger pitch requires different hole spacing on the PCB. However, for new designs, TE parts are functionally equivalent.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The Molex 0761551827 and all TE Connectivity parts (1934303-1, 1934304-1, 1934305-1, 1934306-1) are ROHS3 compliant with UL94 V-0 flammability ratings.

Q: Why is the original Molex 0761550827 marked as obsolete? A: Obsolete status indicates the manufacturer has discontinued active production. The Molex 0761551827 (active status) provides the same functionality with ongoing support. For new designs, either the active Molex variant or TE Connectivity equivalents are recommended.

Q: What is the difference between the four TE Connectivity substitute parts? A: All four TE parts (1934303-1, 1934304-1, 1934305-1, 1934306-1) share identical electrical and mechanical specifications. They differ only in base product number designation and inventory levels. Selection among these parts is based on availability and packaging preferences (all supplied in Tube packaging).
