Molex 0760554607 240-Position Backplane Connector Header

Part Overview

The Molex 0760554607 is a 240-position backplane connector header designed for through-hole PCB mounting. This Impact series connector features male pins with press-fit termination and is configured as a 15×16 matrix with 80 differential pairs. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Direct alternatives and cross-compatible options from both Molex and TE Connectivity are available to maintain design functionality while ensuring current product availability.

Substitute Part Grouping Explanation

Substitution for the Molex 0760554607 is determined by the following critical parameters: 240-position count, through-hole mounting, press-fit termination, male pin configuration, and gold contact finish. Two substitution categories are identified:

Category 1: Direct Molex Equivalent The Molex 0760555607 maintains identical electrical and mechanical specifications with the exception of packaging (Tray vs. standard packaging) and product status (Active vs. Obsolete). This part is the primary direct replacement.

Category 2: Cross-Manufacturer Alternatives (TE Connectivity) The TE Connectivity Z-PACK TinMan series parts (1934331-1, 1934332-1, 1934333-1, 1934334-1) provide functional equivalence with the following parameter variations: pitch increases from 0.053" to 0.075", voltage rating increases from 30V to 250V, current rating is specified at 0.5A (not specified in original), and operating temperature range extends to -65°C to 90°C. These parts maintain 240-position count, through-hole mounting, press-fit termination, male pin configuration, and gold contact finish. The pitch difference represents a mechanical spacing change that requires PCB layout verification.

Engineering Selection Recommendations

For Direct Replacement (No PCB Redesign Required): Select Molex 0760555607. This part is the active equivalent with identical pitch (0.053"), voltage rating (30V), and temperature range (-55°C to 85°C). It maintains full compatibility with existing PCB layouts and maintains ROHS3 compliance. Packaging is supplied in Tray format with 1000 units in stock.

For Cross-Manufacturer Substitution (PCB Layout Verification Required): TE Connectivity Z-PACK TinMan series parts (1934331-1, 1934332-1, 1934333-1, 1934334-1) are functionally equivalent but require PCB layout verification due to pitch change from 0.053" to 0.075". These parts provide enhanced electrical performance with 250V voltage rating and 0.5A current rating specification. All four variants are active products with ROHS3 or RoHS compliance. Selection among the four TE variants is based on inventory availability and internal part numbering conventions; electrical and mechanical specifications are identical across all four.

Frequently Asked Questions (FAQ)

Q: Can Molex 0760555607 be used as a direct drop-in replacement for Molex 0760554607? A: Yes. The 0760555607 is the active equivalent with identical pitch, position count, voltage rating, and temperature range. No PCB layout changes are required.

Q: What is the primary difference between Molex 0760554607 and TE Connectivity alternatives? A: The TE Connectivity Z-PACK TinMan series uses a larger pitch (0.075" vs. 0.053"), which changes the physical spacing of connector positions on the PCB. This requires layout verification before implementation. Electrical ratings are enhanced (250V vs. 30V, 0.5A specified current).

Q: Are all four TE Connectivity part numbers (1934331-1, 1934332-1, 1934333-1, 1934334-1) electrically identical? A: Yes. All four TE Connectivity variants have identical electrical and mechanical specifications. Selection is based on inventory availability and internal part numbering requirements.

Q: What compliance certifications apply to substitute parts? A: All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance. Molex 0760555607 is ROHS3 compliant. TE Connectivity 1934333-1 is ROHS3 compliant; 1934331-1, 1934332-1, and 1934334-1 are RoHS compliant.

Q: If I use a TE Connectivity substitute, what PCB changes are necessary? A: The pitch change from 0.053" to 0.075" requires PCB hole pattern redesign. The connector footprint will be larger, and mounting hole positions will differ. Mechanical clearance and board space must be re-evaluated.

Q: What is the moisture sensitivity level for all parts? A: All parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
