Substitute Part Grouping Explanation

Substitution for the Molex 0760550613 is organized into two categories based on electrical and mechanical compatibility:

Direct Molex Substitute (Same Series): The part 0760551613 is a direct substitute from Molex within the Impact 76055 series. This part maintains identical electrical and mechanical specifications with the exception of packaging format (Tray vs. standard packaging). The 0760551613 is currently in active production status, making it the preferred direct replacement.

Cross-Manufacturer Substitutes (TE Connectivity): Parts 1934331-1, 1934332-1, 1934333-1, and 1934334-1 are TE Connectivity AMP Connectors from the Z-PACK TinMan series. These parts share the following critical parameters with the main part:

240-position connector header configuration
Male pins with through-hole mounting
Press-fit termination
Gold contact finish at 30.0µin thickness
Black color
UL94 V-0 flammability rating
MSL 1 (Unlimited)
ROHS3 or RoHS compliant status

Substitution is permitted based on these matching parameters. However, the TE Connectivity alternatives operate at different pitch (0.075" vs. 0.053"), higher voltage rating (250V vs. 30V), higher current rating (0.5A), and extended temperature range (-65°C to 90°C vs. -55°C to 85°C).

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Option): The Molex 0760551613 is the preferred substitute. It maintains identical electrical and mechanical specifications as the obsolete 0760550613 while offering active product status and current manufacturing support. Both parts are ROHS3 compliant with identical operating parameters. Selection of 0760551613 eliminates design modification requirements and ensures seamless integration into existing PCB layouts.

For Cross-Manufacturer Substitution (When Direct Replacement Unavailable): The TE Connectivity parts (1934331-1, 1934332-1, 1934333-1, 1934334-1) are functionally equivalent alternatives when the direct Molex substitute is unavailable. These parts satisfy the core connector requirements: 240-position header configuration, male pins, through-hole mounting, press-fit termination, gold contact finish, and UL94 V-0 flammability rating.

Critical design considerations for TE Connectivity substitution:

PCB footprint modification is required due to pitch difference (0.075" vs. 0.053")
Higher voltage rating (250V) and current capability (0.5A) provide enhanced electrical margin
Extended operating temperature range (-65°C to 90°C) supports broader environmental applications
All TE Connectivity alternatives maintain RoHS compliance (ROHS3 or RoHS compliant)

Selection among the four TE Connectivity options (1934331-1, 1934332-1, 1934333-1, 1934334-1) is interchangeable from an electrical and mechanical standpoint, with differences limited to RoHS certification level and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0760551613 be used as a direct drop-in replacement for the 0760550613?

A: Yes. The 0760551613 is a direct substitute with identical electrical and mechanical specifications. No design modifications are required. The only difference is packaging format (Tray vs. standard). Both parts share the same 0.053" pitch, 240-position configuration, press-fit termination, and operating parameters.

Q: What is the primary limitation when substituting TE Connectivity parts for the Molex 0760550613?

A: The TE Connectivity alternatives (1934331-1, 1934332-1, 1934333-1, 1934334-1) operate at a different pitch specification (0.075" vs. 0.053"). This difference requires PCB footprint redesign. The connector position count and row/column configuration remain identical, but the physical spacing between pins is larger on TE parts.

Q: Are all four TE Connectivity part numbers (1934331-1, 1934332-1, 1934333-1, 1934334-1) electrically and mechanically identical?

A: Yes, from an electrical and mechanical standpoint, these four parts are equivalent. Differences exist only in RoHS certification level (ROHS3 Compliant vs. RoHS Compliant) and current inventory availability. Selection among these four options does not affect circuit performance or PCB compatibility.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level. The direct Molex substitute (0760551613) and TE Connectivity parts (1934331-1, 1934333-1) are ROHS3 compliant. TE Connectivity parts 1934332-1 and 1934334-1 are RoHS compliant. All parts are suitable for applications requiring environmental and regulatory compliance.

Q: Can the TE Connectivity substitutes handle higher electrical loads than the original Molex part?

A: The TE Connectivity alternatives provide higher voltage rating (250V vs. 30V) and specified current rating (0.5A vs. not specified for the Molex part). These enhanced electrical ratings provide additional design margin but do not change the fundamental connector function. PCB footprint modification remains the primary design consideration for TE substitution.

Q: What packaging formats are available for these substitute parts?

A: The direct Molex substitute (0760551613) is supplied in Tray packaging. All four TE Connectivity alternatives (1934331-1, 1934332-1, 1934333-1, 1934334-1) are supplied in Tube packaging. Packaging selection may affect handling, storage, and assembly process requirements.
