Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0761552107 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins, Impact, Guide Left)
• Position count and array configuration (120 positions, 12 rows × 10 columns)
• Pitch specification (0.053" / 1.35mm)
• Mounting and termination method (Through Hole, Press-Fit)
• Electrical ratings (30V, contact finish specification)
• Environmental compliance (UL94 V-0, ROHS3, REACH Unaffected)

The substitute part 0761553107 maintains identical electrical and mechanical specifications while offering active product status and improved supply availability. Both parts belong to the Impact 76155 series and are directly interchangeable at the PCB assembly level.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761553107 is the direct functional equivalent for the obsolete 0761552107. Both parts are manufactured by Molex within the Impact 76155 series and share identical electrical specifications, mechanical dimensions, and environmental ratings. The primary distinction is product lifecycle status: 0761553107 maintains active manufacturing status with current supply availability, while 0761552107 is obsolete.

For new designs and ongoing production support, 0761553107 is the appropriate selection. Both parts satisfy ROHS3 compliance and REACH requirements. The packaging difference (bulk versus tray) does not affect functional compatibility and relates only to supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can 0761553107 be used as a direct replacement for 0761552107 in existing PCB designs?

A: Yes. Both connectors are electrically and mechanically identical. They share the same 120-position configuration, 0.053" pitch, press-fit termination, and gold contact finish. No PCB layout modifications are required.

Q: What is the significance of the product status difference?

A: The 0761552107 is classified as obsolete, indicating Molex has discontinued manufacturing. The 0761553107 maintains active status with ongoing production. For new designs and long-term supply security, 0761553107 is the recommended choice.

Q: Are there packaging considerations when switching between these parts?

A: The 0761552107 is supplied in bulk packaging, while 0761553107 is supplied in trays. This affects only receiving, storage, and handling procedures. The connector itself is functionally identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for material flammability. Environmental and regulatory requirements are satisfied by either part.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is based on connector type (Header, Male Pins), position count (120), array configuration (12 × 10), pitch (0.053"), mounting method (Through Hole), termination type (Press-Fit), contact finish (Gold), and electrical ratings (30V, -55°C to 85°C operating range).
