Engineering Selection Recommendations

Molex 0761551608 is the direct Molex equivalent and primary substitute. This part maintains identical electrical and mechanical specifications to the obsolete 0761550608 while offering active product status. The transition from obsolete to active status ensures long-term availability and supply chain continuity. Packaging is provided in Tray format.

TE Connectivity Z-PACK TinMan Series (1934315-1, 1934316-1, 1934317-1, 1934318-1) represents cross-manufacturer alternatives from TE Connectivity AMP Connectors. These parts maintain all primary matching criteria including 192 positions, 12×16 configuration, through-hole press-fit termination, gold contact finish, UL94 V-0 flammability rating, and MSL 1 rating. All four TE Connectivity parts are in active production status.

Key differences in TE Connectivity alternatives include:

Pitch specification of 0.075" (1.90mm) versus 0.053" (1.35mm) in the original part
Enhanced voltage rating of 250V versus 30V
Defined current rating of 0.5A
Extended operating temperature range of -65°C to 90°C

All substitute parts maintain ROHS3 compliance or equivalent RoHS compliance status. Selection among TE Connectivity alternatives should be based on packaging requirements: 1934315-1 and 1934317-1 are supplied in Tube packaging, while 1934316-1 is supplied in Bulk packaging, and 1934318-1 is supplied in Tube packaging.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761551608 be used as a direct replacement for the obsolete 0761550608?

A: Yes. The Molex 0761551608 maintains identical specifications across all primary matching criteria: 192 positions, 0.053" pitch, 12×16 configuration, through-hole press-fit termination, gold contact finish, UL94 V-0 rating, and MSL 1 classification. The primary difference is product status transition from obsolete to active.

Q: What is the primary difference between Molex and TE Connectivity substitute options?

A: The Molex 0761551608 maintains the original 0.053" pitch specification, while TE Connectivity Z-PACK TinMan series parts (1934315-1, 1934316-1, 1934317-1, 1934318-1) feature a 0.075" pitch. This pitch difference requires PCB layout verification before substitution. TE Connectivity alternatives also provide enhanced voltage rating (250V vs. 30V) and defined current rating (0.5A).

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0761551608 is ROHS3 compliant. TE Connectivity parts 1934315-1 and 1934318-1 are ROHS3 compliant, while 1934316-1 and 1934317-1 are RoHS compliant. All parts meet applicable RoHS requirements.

Q: What packaging options are available for substitute parts?

A: Molex 0761551608 is supplied in Tray packaging. TE Connectivity alternatives are available in multiple packaging formats: 1934315-1 and 1934317-1 in Tube, 1934316-1 in Bulk, and 1934318-1 in Tube. Packaging selection should align with assembly and inventory management requirements.

Q: Can TE Connectivity parts be used in applications originally designed for the Molex 0761550608?

A: TE Connectivity Z-PACK TinMan series parts maintain functional equivalence across all primary matching criteria. However, the 0.075" pitch specification differs from the original 0.053" pitch. PCB layout compatibility must be verified before implementation. If the original PCB design accommodates the 0.075" pitch spacing, TE Connectivity parts provide enhanced electrical specifications including higher voltage rating and defined current capacity.

Q: What is the significance of the operating temperature range difference?

A: The original Molex 0761550608 operates across -55°C to 85°C. TE Connectivity alternatives extend this range to -65°C to 90°C, providing broader environmental operating capability. This extended range does not restrict use in applications within the original temperature specification.

Q: Are all substitute parts available in current inventory?

A: Yes. Molex 0761551608 has 935 pieces in stock. TE Connectivity alternatives have the following inventory levels: 1934315-1 (961 pieces), 1934316-1 (1,082 pieces), 1934317-1 (1,135 pieces), and 1934318-1 (2,240 pieces). All parts are new original stock.
