Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0760554604 is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of Positions: 240 (exact match required)
• Connector Type: Header, Male Pins (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination: Press-Fit (exact match required)
• Contact Finish: Gold (exact match required)
• Material Flammability Rating: UL94 V-0 (exact match required)
• RoHS Compliance: ROHS3 or equivalent (exact match required)

Allowable Parameter Variations:

• Pitch: 0.053" (1.35mm) to 0.075" (1.90mm) — different pitch values indicate different connector families but maintain 240-position, 15×16 configuration
• Voltage Rating: 30V to 250V — higher voltage ratings are acceptable for applications requiring 30V operation
• Operating Temperature: -55°C ~ 85°C to -65°C ~ 90°C — extended temperature ranges are acceptable
• Current Rating: Not specified in main part; substitute parts rated at 0.5A are acceptable
• Connector Style: Impact (Guide Right) to High Speed — different electrical performance characteristics but same mechanical interface

Direct Equivalent:

• Molex 0760555604 — identical specifications with Active product status and Tray packaging

Cross-Manufacturer Substitutes:

• TE Connectivity 1934331-1, 1934332-1, 1934333-1, 1934334-1 — all from Z-PACK TinMan series with 0.075" pitch and higher voltage/temperature ratings

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required): Select Molex 0760555604. This part maintains identical electrical and mechanical specifications to the 0760554604 while offering Active product status, ensuring long-term availability and supply chain stability. Both parts operate within the same voltage (30V) and temperature (-55°C ~ 85°C) ranges with matching pitch (0.053") and contact configuration.

For Cross-Manufacturer Substitution (Design Verification Required): TE Connectivity Z-PACK TinMan series (1934331-1, 1934332-1, 1934333-1, 1934334-1) are acceptable substitutes when PCB layout accommodates the larger 0.075" (1.90mm) pitch. These parts provide enhanced electrical performance with 250V voltage rating and extended operating temperature range (-65°C ~ 90°C). All four TE parts maintain identical specifications; selection among them depends on packaging preference (Tube) and RoHS certification level (ROHS3 or RoHS Compliant).

Compliance Considerations: All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance, meeting standard regulatory requirements. The TE Connectivity parts offer higher voltage and temperature margins, providing additional design headroom for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0760555604 as a direct replacement for 0760554604? A: Yes. The 0760555604 is a direct equivalent with identical specifications. The primary difference is product status (Active vs. Obsolete) and packaging (Tray vs. unspecified), making it the preferred choice for new procurement.

Q: What is the main difference between Molex Impact series and TE Z-PACK TinMan series? A: The primary difference is connector pitch: Molex Impact uses 0.053" (1.35mm) pitch, while TE Z-PACK TinMan uses 0.075" (1.90mm) pitch. This requires PCB layout modification. TE parts also offer higher voltage (250V vs. 30V) and extended temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C).

Q: Can I use TE Connectivity parts without modifying my PCB? A: No. The 0.075" pitch of TE parts requires different PCB hole spacing than the 0.053" pitch of Molex parts. PCB redesign is necessary for mechanical and electrical compatibility.

Q: Are all four TE Connectivity part numbers (1934331-1, 1934332-1, 1934333-1, 1934334-1) interchangeable? A: Yes, electrically and mechanically. All four parts share identical specifications. Selection depends on packaging preference (all use Tube packaging) and RoHS certification level. Parts 1934331-1 and 1934333-1 carry ROHS3 certification, while 1934332-1 and 1934334-1 carry RoHS Compliant certification.

Q: What is the significance of the 0.5A current rating on TE parts versus unspecified rating on Molex parts? A: The TE parts explicitly specify 0.5A per contact current rating. The Molex 0760554604 does not provide this specification. For applications requiring current rating verification, the TE parts offer documented electrical performance.

Q: Which substitute should I select for new designs? A: For new designs, select Molex 0760555604 if your PCB layout accommodates 0.053" pitch. If higher voltage margin or extended temperature range is required, select TE Connectivity parts (1934331-1, 1934332-1, 1934333-1, or 1934334-1) with corresponding PCB redesign for 0.075" pitch accommodation.
