Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0761552104 is determined by strict equivalence across the following critical parameters:

• Connector type and style: Header, Male Pins, Impact style with Guide Left orientation
• Electrical specifications: 120 positions, 0.053" (1.35mm) pitch, 10 differential pairs contact layout
• Physical configuration: 12 rows × 10 columns, through-hole mounting with press-fit termination
• Environmental and compliance ratings: Operating temperature range -55°C ~ 85°C, 30V voltage rating, UL94 V-0 flammability, ROHS3 compliance

The substitute part 0761553104 maintains identical electrical and mechanical specifications while differing only in product status (Active vs. Obsolete) and packaging format (Tray vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761553104 is the direct equivalent substitute for the obsolete 0761552104. Both parts are manufactured by Molex within the Impact 76155 series and maintain identical electrical, mechanical, and environmental specifications. The primary distinction is product lifecycle status: the 0761553104 is currently in active production, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The gold contact finish with specified thickness and UL94 V-0 flammability rating are maintained across both variants, ensuring compatibility with existing PCB designs and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 0761553104 be used as a direct replacement for the 0761552104 in existing designs?

A: Yes. The 0761553104 is electrically and mechanically identical to the 0761552104. All critical parameters including position count, pitch, mounting type, contact configuration, and environmental ratings are equivalent. The substitute part is suitable for direct PCB layout and assembly compatibility.

Q: What is the difference between the two part numbers?

A: The 0761553104 differs from the 0761552104 in product status (Active vs. Obsolete) and packaging format (Tray vs. standard). All functional and electrical specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0761552104 and 0761553104 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Does packaging format affect connector performance?

A: No. Packaging format (Tray vs. standard) does not affect electrical performance, mechanical fit, or functional characteristics. The difference is limited to handling and storage logistics.

Q: What is the contact layout configuration for these connectors?

A: Both parts feature 10 differential pairs contact layout within the 120-position, 12 × 10 row-column configuration at 0.053" (1.35mm) pitch.
