Engineering Selection Recommendations

Direct Molex Equivalent: The Molex 0760555608 is the primary substitute for the obsolete 0760554608. Both parts share identical electrical and mechanical specifications, with the only difference being packaging format (Tray) and active product status. This substitution requires no design modification and maintains full compatibility with existing PCB layouts and assembly processes.

TE Connectivity Z-PACK TinMan Series (1934331-1, 1934332-1, 1934333-1, 1934334-1): These manufacturer-recommended alternatives are suitable when design flexibility permits pitch accommodation. The TE parts feature enhanced electrical ratings (250V vs. 30V, 0.5A current rating) and extended operating temperature range (-65°C to 90°C vs. -55°C to 85°C). The primary design consideration is the increased pitch (0.075" vs. 0.053"), which requires PCB layout verification. All TE alternatives maintain UL94 V-0 flammability compliance and MSL 1 rating. Selection among the four TE variants (1934331-1, 1934332-1, 1934333-1, 1934334-1) depends on RoHS certification requirements: 1934331-1 and 1934333-1 carry ROHS3 compliance, while 1934332-1 and 1934334-1 carry standard RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0760555608 be used as a direct replacement for the 0760554608?

A: Yes. Both parts are functionally equivalent with identical connector specifications, pitch, position count, and electrical ratings. The 0760555608 is the active production equivalent and requires no design changes.

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

A: The Molex 0760555608 maintains the original 0.053" (1.35mm) pitch. The TE Connectivity Z-PACK TinMan series uses 0.075" (1.90mm) pitch, requiring PCB layout verification. TE parts offer higher voltage (250V vs. 30V) and current (0.5A) ratings with extended temperature range.

Q: Can I use a TE Connectivity part if my PCB is designed for 0.053" pitch?

A: No. The TE parts use 0.075" pitch and will not fit PCBs designed for 0.053" pitch spacing. PCB layout modification is required for TE substitutes.

Q: Are all TE Connectivity alternatives electrically interchangeable?

A: Yes, electrically and mechanically. The four TE variants (1934331-1, 1934332-1, 1934333-1, 1934334-1) are identical in function. Selection depends on RoHS certification requirements: 1934331-1 and 1934333-1 are ROHS3 compliant; 1934332-1 and 1934334-1 are RoHS compliant.

Q: What compliance certifications apply to all substitutes?

A: All parts carry UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. RoHS compliance varies by part number as noted above.

Q: Which substitute offers the best inventory availability?

A: TE Connectivity 1934331-1 has the highest current stock at 1854 pieces, followed by 1934334-1 at 1004 pieces. Molex 0760555608 has 903 pieces available.
