Molex 0760555606 240-Position Backplane Connector Header – Equivalent & Substitute Parts

Part Overview

The Molex 0760555606 is a 240-position backplane connector header designed for through-hole PCB mounting. This Impact series connector features male pins with a 0.053" (1.35mm) pitch, configured in a 15×16 matrix with guide-right orientation and press-fit termination. The connector is rated for 30V operation across an extended temperature range of -55°C to 85°C and carries UL94 V-0 flammability certification. Currently in active production status with 646 units in stock, this component serves applications requiring high-density interconnection with reliable press-fit contact engagement.

Substitute parts are identified to address inventory availability, alternative sourcing strategies, or design flexibility requirements while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0760555606 are identified from the TE Connectivity AMP Connectors Z-PACK TinMan series. Substitution eligibility is determined by the following critical parameters:

Matching Parameters:

• Connector type: Header, Male Pins
• Number of positions: 240
• Matrix configuration: 15 Rows × 16 Columns
• Mounting type: Through Hole
• Termination method: Press-Fit
• Contact finish: Gold, 30.0µin (0.76µm)
• Color: Black
• Material flammability: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8536.69.4040

Differing Parameters:

• Pitch: 0.075" (1.90mm) versus 0.053" (1.35mm)
• Connector style: High Speed versus Impact, Guide Right
• Voltage rating: 250V versus 30V
• Current rating: 0.5A (specified) versus unspecified
• Operating temperature range: -65°C to 90°C versus -55°C to 85°C
• Series designation: Z-PACK TinMan versus Impact 76055

The substitute parts maintain functional equivalence in position count, mounting methodology, and contact technology while operating within broader electrical and thermal specifications.

Engineering Selection Recommendations

Selection between the Molex 0760555606 and TE Connectivity substitute parts (1934331-1, 1934332-1, 1934334-1) is determined by application-specific requirements and compliance mandates.

Molex 0760555606 Selection Criteria:

• Applications requiring 0.053" (1.35mm) pitch spacing for high-density interconnection
• Systems with 30V maximum operating voltage
• Designs constrained to -55°C to 85°C thermal envelope
• ROHS3 compliance requirement
• Tray packaging preference for automated assembly processes

TE Connectivity Substitute Selection Criteria:

• Applications accommodating 0.075" (1.90mm) pitch spacing
• Systems utilizing 250V rated connectors for enhanced voltage margin
• Designs requiring -65°C to 90°C extended thermal operating range
• RoHS compliance (ROHS3 or general RoHS)
• Tube packaging for manual or selective assembly operations
• Higher inventory availability (859–1854 units in stock)

All substitute parts maintain active product status, UL94 V-0 flammability certification, unlimited moisture sensitivity level (MSL 1), and identical contact finish specifications. The TE Connectivity parts provide broader electrical and thermal specifications, making them suitable for applications with less stringent pitch requirements but higher voltage or temperature margins.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity parts 1934331-1, 1934332-1, and 1934334-1 directly replace the Molex 0760555606 in existing PCB designs?

A: Direct PCB replacement is not possible due to pitch difference. The Molex part uses 0.053" (1.35mm) pitch, while TE Connectivity substitutes use 0.075" (1.90mm) pitch. PCB footprint redesign is required for mechanical and electrical compatibility.

Q: What is the primary functional difference between the Molex Impact series and TE Connectivity Z-PACK TinMan series?

A: The Molex Impact series is optimized for fine-pitch (0.053") high-density applications with guide-right orientation. The TE Connectivity Z-PACK TinMan series operates at wider pitch (0.075") with high-speed signal integrity features. Both use identical press-fit termination and contact finish technology.

Q: Are all substitute parts electrically interchangeable in terms of voltage and current ratings?

A: No. The Molex 0760555606 is rated for 30V with unspecified current rating. TE Connectivity substitutes are rated for 250V at 0.5A per contact. Applications operating above 30V require TE Connectivity parts; applications below 30V can use either series.

Q: What is the impact of packaging differences (Tray versus Tube)?

A: Tray packaging (Molex) is optimized for high-speed automated assembly. Tube packaging (TE Connectivity) is suitable for manual or lower-volume assembly processes. Packaging does not affect electrical or mechanical performance.

Q: Do all parts meet the same RoHS compliance standards?

A: The Molex 0760555606 is ROHS3 compliant. TE Connectivity 1934331-1 is ROHS3 compliant; parts 1934332-1 and 1934334-1 are RoHS compliant (specific version not specified by vendor). All parts are REACH unaffected or vendor-undefined, indicating no restricted substances.

Q: Which substitute part should be selected if thermal performance is critical?

A: TE Connectivity substitutes operate across -65°C to 90°C, providing 10°C lower minimum and 5°C higher maximum temperature limits compared to the Molex part (-55°C to 85°C). Select TE Connectivity parts for applications requiring extended thermal margins.
