Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0757054604 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; I-Trac, Guide Right)
• Position count and array configuration (132 positions, 11 rows × 6 columns)
• Mounting and termination method (Through Hole, Press-Fit)
• Contact material and finish specification (Gold, 30.0µin thickness)
• Electrical ratings (120V, UL94 V-0)
• Environmental compliance (ROHS3, MSL 1)
• Operating temperature range (-55°C to 80°C)

The substitute part identified maintains full electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0757055604 is the direct functional equivalent for the obsolete 0757054604. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the substitute part is currently active in Molex's product line, ensuring ongoing availability and supply chain continuity.

The substitute part carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Packaging differs only in format (Tray for the substitute), which does not affect component functionality or PCB integration.

For applications requiring the 132-position I-Trac header with male pins, through-hole mounting, and the specified electrical and environmental ratings, the 0757055604 provides full compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 0757055604 be used as a direct replacement for the 0757054604 without PCB redesign?

A: Yes. Both parts share identical connector type, position count, array configuration, mounting method, contact specifications, and electrical ratings. No PCB layout modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The main part (0757054604) is obsolete and no longer manufactured. The substitute (0757055604) is active and available from current inventory, ensuring reliable procurement for new builds and field replacements.

Q: Does the packaging difference (unspecified vs. Tray) affect compatibility?

A: No. Packaging format does not impact electrical or mechanical performance. The Tray packaging of the substitute part is a logistics consideration only.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited moisture sensitivity level). The substitute part additionally carries REACH unaffected status.

Q: What are the critical parameters that define substitution eligibility for this connector?

A: Substitution is based on matching connector type (Header, Male Pins), style (I-Trac, Guide Right), position count (132), array configuration (11 rows × 6 columns), mounting method (Through Hole), termination type (Press-Fit), contact finish (Gold, 30.0µin), electrical ratings (120V), flammability rating (UL94 V-0), and operating temperature range (-55°C to 80°C).
