Parameter Comparison

Engineering Selection Recommendations

The Molex 0761553108 is the direct equivalent substitute for the obsolete 0761552108. Both parts are manufactured by Molex within the Impact 76155 series and maintain identical electrical and mechanical specifications across all critical parameters.

Primary Advantage: The 0761553108 carries active product status, ensuring continued availability and supply chain reliability. This part is ROHS3 compliant and maintains the same UL94 V-0 flammability rating, supporting equivalent regulatory compliance in applications requiring these certifications.

Packaging Consideration: The substitute is supplied in tray packaging, which is standard for active production parts and provides improved handling and storage compared to bulk packaging.

Direct Substitution: No design modifications, PCB layout changes, or assembly procedure adjustments are required when transitioning from 0761552108 to 0761553108. The parts are mechanically and electrically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the 0761553108 be used as a direct replacement for the 0761552108 without PCB modifications?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting method, and electrical ratings. No PCB layout or assembly changes are necessary.

Q: What is the primary difference between these two parts?

A: The 0761552108 is obsolete, while the 0761553108 is active. The substitute also uses tray packaging instead of bulk packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry ROHS3 compliance and UL94 V-0 flammability rating. The 0761553108 also carries REACH Unaffected status, providing additional regulatory documentation.

Q: Does the tray packaging affect compatibility?

A: No. Tray packaging is a handling and storage format only. The connector itself is identical to the bulk-packaged version. Tray packaging is standard for active production parts and provides better protection during shipment and storage.

Q: What is the contact finish specification for both parts?

A: Both parts feature gold-plated contacts with a thickness of 30.0µin (0.76µm), ensuring equivalent electrical performance and corrosion resistance.

Q: Are there any temperature or voltage rating differences?

A: No. Both parts operate across the identical temperature range of -55°C ~ 85°C and carry a 30V voltage rating.
