Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0760550628 is determined by the following critical parameters:

Primary Compatibility Criteria:

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

Substitute Parts Identified:

1. Direct Molex Equivalent (0760551628) – Same series, same pitch (0.053"), active product status, identical electrical and mechanical specifications. Differs only in packaging (Tray vs. standard).

2. TE Connectivity AMP Connectors (1934331-1, 1934332-1, 1934333-1, 1934334-1) – Z-PACK TinMan series headers with 240 positions, male pins, through-hole mounting, and press-fit termination. These parts maintain core compatibility but operate at different pitch (0.075"), higher voltage rating (250V vs. 30V), and higher current rating (0.5A). All are active products with ROHS3 or RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The Molex 0760551628 is the recommended direct substitute. It maintains identical electrical and mechanical specifications, including pitch (0.053"), voltage rating (30V), and operating temperature range (-55°C ~ 85°C). The only difference is packaging format (Tray). This part is active and ROHS3 compliant, ensuring long-term availability and regulatory compliance.

For Alternative Applications: The TE Connectivity AMP Connectors (1934331-1, 1934332-1, 1934333-1, 1934334-1) are suitable alternatives when PCB layout accommodates the larger pitch (0.075" vs. 0.053"). These parts offer enhanced electrical performance with higher voltage rating (250V) and specified current rating (0.5A), along with extended operating temperature range (-65°C ~ 90°C). All four TE variants are active products with RoHS compliance.

Compliance Considerations: All substitute parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level, ensuring compatibility with existing design certifications and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0760551628 be used as a direct replacement for the 0760550628? A: Yes. Both parts are from the Molex Impact 76055 series with identical specifications: 240 positions, 0.053" pitch, through-hole mounting, press-fit termination, and gold contact finish. The only difference is packaging (Tray vs. standard). No PCB redesign is required.

Q: What are the key differences between the Molex and TE Connectivity substitutes? A: The primary differences are pitch (0.053" for Molex vs. 0.075" for TE), voltage rating (30V vs. 250V), and current rating (not specified for Molex vs. 0.5A for TE). TE parts also offer extended operating temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C). PCB layout changes are required for TE substitutes due to pitch difference.

Q: Are all substitute parts RoHS compliant? A: Yes. The Molex 0760551628 is ROHS3 compliant. TE Connectivity parts 1934331-1 and 1934333-1 are ROHS3 compliant; parts 1934332-1 and 1934334-1 are RoHS compliant. All meet regulatory requirements.

Q: What is the difference between the four TE Connectivity part numbers (1934331-1 through 1934334-1)? A: All four TE parts share identical electrical and mechanical specifications. The differences are in base product numbers (1934331 through 1934334) and potentially internal design variants within the Z-PACK TinMan series. Selection among these variants should be based on availability and specific design requirements.

Q: Can TE Connectivity parts be used without PCB modifications? A: No. TE parts have a larger pitch (0.075" vs. 0.053"), requiring PCB layout redesign. Hole spacing and trace routing must be adjusted to accommodate the new pitch. Mechanical fit and electrical performance depend on proper PCB layout adaptation.

Q: What is the moisture sensitivity level for all parts? A: All parts are MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or humidity control requirements.
