Substitute Part Grouping Explanation

Substitute parts for the Molex 0760556607 are grouped into two categories based on electrical and mechanical compatibility:

Category 1: Direct Molex Equivalents (Same Series) Parts 0760553607 and 0760557607 are direct equivalents within the Molex Impact 76055 series. These parts maintain identical electrical and mechanical specifications including pitch (0.053"/1.35mm), position count (240), row/column configuration (15×16), contact finish (gold, 30.0µin), flammability rating (UL94 V-0), operating temperature range (-55°C ~ 85°C), and voltage rating (30V). The primary difference is product status: both are active production parts, whereas the original is obsolete. These substitutes are functionally interchangeable for PCB layout and assembly purposes.

Category 2: TE Connectivity Cross-Reference (Different Series) 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 same connector type (header, male pins), position count (240), row/column configuration (15×16), mounting type (through hole), termination method (press-fit), contact finish (gold, 30.0µin), flammability rating (UL94 V-0), and RoHS compliance. However, they differ in pitch (0.075"/1.90mm vs. 0.053"/1.35mm), operating temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C), voltage rating (250V vs. 30V), and current rating (0.5A vs. unspecified). These parts are not direct mechanical substitutes due to pitch differences but represent alternative connector solutions for 240-position backplane applications.

Engineering Selection Recommendations

For Direct Replacement (Same PCB Layout): Select Molex 0760553607 or 0760557607 when the original PCB design and connector footprint must remain unchanged. Both parts are active production items with identical pitch (0.053"/1.35mm), electrical ratings, and mechanical dimensions. These substitutes provide continuity for legacy system support and new production runs without PCB redesign. Both maintain ROHS3 compliance and UL94 V-0 flammability certification.

For Alternative Connector Solutions (PCB Redesign Acceptable): TE Connectivity parts 1934331-1, 1934332-1, 1934333-1, and 1934334-1 are suitable when PCB layout modification is feasible. These parts offer enhanced electrical performance with higher voltage rating (250V vs. 30V), extended operating temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C), and specified current rating (0.5A). The larger pitch (0.075"/1.90mm) requires PCB footprint adjustment. All four TE Connectivity variants are active production parts with RoHS compliance. Selection among these four variants should be based on specific application requirements and availability.

Frequently Asked Questions (FAQ)

Q: Can Molex 0760553607 or 0760557607 be used as direct replacements for the obsolete 0760556607? A: Yes. Both parts are functionally and mechanically identical to the original part, with identical pitch, position count, row/column configuration, contact specifications, and electrical ratings. They require no PCB layout changes and are direct substitutes for assembly and design purposes.

Q: What is the primary difference between the Molex Impact 76055 series substitutes and the TE Connectivity Z-PACK TinMan series? A: The primary difference is connector pitch. Molex Impact 76055 parts use 0.053" (1.35mm) pitch, while TE Connectivity Z-PACK TinMan parts use 0.075" (1.90mm) pitch. This pitch difference requires different PCB footprints and cannot be used interchangeably without PCB redesign. Additionally, TE Connectivity parts offer higher voltage rating (250V vs. 30V) and extended temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C).

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts are RoHS compliant. Molex parts 0760553607 and 0760557607 are ROHS3 compliant. TE Connectivity parts 1934331-1, 1934333-1 are ROHS3 compliant, while 1934332-1 and 1934334-1 are RoHS compliant.

Q: What packaging options are available for these substitutes? A: Molex 0760553607 and 0760557607 are supplied in Tray packaging. TE Connectivity parts 1934331-1, 1934332-1, 1934333-1, and 1934334-1 are supplied in Tube packaging.

Q: Can the TE Connectivity parts be used if the original design specifies 30V voltage rating? A: Yes, from an electrical standpoint. TE Connectivity parts have a 250V voltage rating, which exceeds the 30V requirement. However, mechanical compatibility requires PCB redesign due to pitch differences (0.075" vs. 0.053"). Verify that the higher voltage rating and extended temperature range do not conflict with other system design constraints.

Q: What is the contact layout difference between the main part and TE Connectivity substitutes? A: The main Molex part specifies 80 differential pairs in its contact layout. TE Connectivity parts do not specify contact layout configuration in the provided data. Confirm differential pair requirements with the connector manufacturer before selection.
