Substitute Part Grouping Explanation

Substitution for the Molex 0760550604 is organized into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Same Series): The Molex 0760551604 maintains identical electrical and mechanical specifications as the main part, differing only in packaging format (Tray vs. standard packaging). This part is active and directly interchangeable.

Cross-Manufacturer Alternatives (TE Connectivity Z-PACK TinMan Series): The TE Connectivity parts (1934331-1, 1934332-1, 1934333-1, 1934334-1) are functionally equivalent based on the following allowed parameters:

240-position connector header configuration
Male pin orientation
Through-hole mounting
Press-fit termination
15 × 16 row/column arrangement
Gold contact finish at 30.0µin thickness
Black color
UL94 V-0 flammability rating
MSL 1 rating
ROHS3 or RoHS compliance

These parts differ in pitch specification (0.075" vs. 0.053"), voltage rating (250V vs. 30V), current rating (0.5A vs. unspecified), and operating temperature range (-65°C to 90°C vs. -55°C to 85°C), representing design variations within the backplane connector category.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical and Mechanical Specifications): The Molex 0760551604 is the primary equivalent, offering identical pitch (0.053"), voltage rating (30V), and operating temperature range (-55°C to 85°C). Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification. The 0760551604 is currently active in production with higher inventory availability (1065 units vs. 884 units for the obsolete 0760550604).

For Cross-Manufacturer Substitution (TE Connectivity Z-PACK TinMan Series): The TE Connectivity parts (1934331-1, 1934332-1, 1934333-1, 1934334-1) are suitable for applications where the higher voltage rating (250V) and extended operating temperature range (-65°C to 90°C) provide design margin. These parts carry active product status and higher inventory levels. Selection among the four TE variants should be based on specific application requirements and supply chain considerations, as all four maintain identical electrical and mechanical specifications.

All substitute options maintain compliance with RoHS and UL94 V-0 standards, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0760551604 be used as a direct replacement for the 0760550604? A: Yes. Both parts share identical connector specifications: 240 positions, 0.053" pitch, 15 × 16 configuration, through-hole mounting, press-fit termination, and 30V voltage rating. The only difference is packaging format (Tray vs. standard). Both are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What are the key differences between the Molex Impact series and the TE Connectivity Z-PACK TinMan series? A: The primary differences are pitch (0.053" vs. 0.075"), voltage rating (30V vs. 250V), current rating (unspecified vs. 0.5A), and operating temperature range (-55°C to 85°C vs. -65°C to 90°C). Both series maintain 240-position configuration, male pin orientation, through-hole mounting, and press-fit termination with identical contact finish specifications.

Q: Are the four TE Connectivity part numbers (1934331-1, 1934332-1, 1934333-1, 1934334-1) interchangeable? A: Yes. All four TE parts share identical electrical and mechanical specifications within the Z-PACK TinMan series. Selection should be based on inventory availability, packaging preference (all supplied in Tube format), and supply chain logistics.

Q: What compliance certifications apply to all substitute parts? A: All parts listed maintain UL94 V-0 material flammability rating, MSL 1 (Unlimited) moisture sensitivity level, and RoHS or ROHS3 compliance. The Molex parts are specifically ROHS3 compliant. TE parts carry either ROHS3 or RoHS compliance designations.

Q: Can TE Connectivity parts be used in applications designed for the Molex 0760550604? A: TE parts are functionally equivalent for 240-position backplane connector applications. However, the 0.075" pitch difference requires PCB layout modification. The higher voltage rating (250V) and extended temperature range (-65°C to 90°C) provide additional design margin for applications operating within the original -55°C to 85°C specification.

Q: What is the inventory status for each substitute part? A: Molex 0760551604: 1065 units. TE 1934331-1: 1854 units. TE 1934332-1: 859 units. TE 1934333-1: 924 units. TE 1934334-1: 1004 units. All substitute parts are in active production status.
