Molex 0760556608 Equivalent & Substitute Parts

Part Overview

The Molex 0760556608 is a 240-position backplane connector header with male pins for through-hole PCB mounting. This Impact series connector features a 0.053" (1.35mm) pitch, 15 rows by 16 columns configuration, and gold-plated contacts rated for 30V operation across -55°C to 85°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the Molex 0760556608 is organized into two categories based on electrical and mechanical compatibility:

Category 1: Direct Molex Impact Series Substitutes

Parts 0760553608 and 0760557608 maintain identical electrical and mechanical specifications: 240 positions, 0.053" pitch, 15×16 configuration, through-hole press-fit termination, gold contact finish, 30V rating, and -55°C to 85°C operating range. These parts differ only in packaging (tray vs. original packaging) and product status (active vs. obsolete). Both are ROHS3 compliant with MSL 1 rating.

Category 2: TE Connectivity Z-PACK TinMan High-Speed Substitutes

Parts 1934331-1, 1934332-1, 1934333-1, and 1934334-1 are manufacturer-recommended alternatives from TE Connectivity. These maintain the same 240-position count, 15×16 row-column configuration, through-hole press-fit termination, gold contact finish, and UL94 V-0 flammability rating. However, they operate at a different pitch (0.075" / 1.90mm), higher voltage rating (250V vs. 30V), higher current rating (0.5A), and extended temperature range (-65°C to 90°C). All are active products with ROHS3 or RoHS compliance.

Substitution is valid only when the receiving design accommodates the pitch and electrical parameter differences specified above.

Engineering Selection Recommendations

For Direct Replacement (Same Pitch and Electrical Ratings): Select Molex 0760553608 or 0760557608 when PCB layout and electrical design are fixed to the 0.053" pitch and 30V rating. Both parts are active products with ROHS3 compliance and identical functional specifications to the obsolete 0760556608. Packaging differs (tray vs. original), but electrical and mechanical performance are equivalent.

For Design Flexibility (Higher Voltage and Temperature Range): TE Connectivity 1934331-1, 1934332-1, 1934333-1, or 1934334-1 are suitable when the design can accommodate a 0.075" pitch and benefit from 250V voltage rating and -65°C to 90°C operating range. These parts are active products with established supply chains. Selection among these four TE parts is based on packaging preference (all supplied in tubes) and RoHS certification level (ROHS3 or RoHS compliant).

All substitute options maintain UL94 V-0 flammability rating, gold contact finish, and MSL 1 moisture sensitivity level, ensuring compliance with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I use the TE Connectivity parts as direct drop-in replacements for the Molex 0760556608? A: No. The TE Connectivity parts operate at 0.075" pitch versus the Molex 0.053" pitch. PCB footprints and hole spacing are different. Use TE parts only if your design can be modified to accommodate the larger pitch.

Q: What is the key difference between Molex 0760553608 and 0760557608? A: Both parts are electrically and mechanically identical to the obsolete 0760556608. The difference is packaging: 0760553608 ships in trays, while 0760557608 also ships in trays. Both are active products suitable for new designs or obsolescence replacement.

Q: Why do the TE Connectivity parts have a higher voltage rating (250V vs. 30V)? A: The TE Z-PACK TinMan series is designed for high-speed, high-reliability applications. The 250V rating reflects the broader application range of this connector family. Your design voltage requirement determines whether this higher rating is necessary.

Q: Are all substitute parts RoHS compliant? A: Yes. The Molex substitutes (0760553608, 0760557608) are ROHS3 compliant. TE Connectivity parts are either ROHS3 or RoHS compliant. All meet environmental compliance requirements for standard PCB assembly.

Q: What is MSL 1 rating, and why does it matter? A: MSL 1 (Moisture Sensitivity Level 1) means unlimited shelf life without moisture control. All listed parts carry MSL 1, eliminating moisture-related handling constraints during assembly and storage.

Q: Can I mix Molex and TE Connectivity connectors in the same design? A: Only if your PCB layout supports both 0.053" and 0.075" pitches. Mixing requires separate footprints and cannot be done on a single connector position. Standardize on one pitch for a given connector location.
