Engineering Selection Recommendations

The Molex 0760554103 is obsolete; however, two active substitute parts maintain full electrical and mechanical compatibility:

0760555103 is the direct functional equivalent with identical guide-right orientation. This part is currently in active production status and represents the primary substitute for new designs and ongoing production requirements. Both parts share identical connector style, pitch, position count, and all electrical specifications.

0760757103 provides an alternative with guide-left orientation instead of guide-right. This part is also in active production status and maintains all electrical and mechanical parameters. Selection between guide-right and guide-left variants depends on PCB layout and mechanical assembly requirements specific to the application.

Both substitute parts carry ROHS3 compliance and UL94 V-0 flammability certification, matching the original part's regulatory status. Packaging is provided in tray format for both active alternatives.

Frequently Asked Questions (FAQ)

Q: Can 0760555103 directly replace 0760554103 in existing designs?

A: Yes. The 0760555103 maintains identical electrical specifications, pitch, position count, mounting type, and termination method. Both parts feature guide-right orientation and are functionally equivalent.

Q: What is the difference between guide-right and guide-left orientation?

A: Guide orientation refers to the mechanical keying feature on the connector header. Guide-right (0760554103, 0760555103) and guide-left (0760557103) variants differ only in this mechanical orientation. Selection depends on PCB layout and mating connector alignment requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The main part (0760554103) and both substitutes (0760555103, 0760557103) are ROHS3 compliant.

Q: What is the difference in packaging between the main part and substitutes?

A: The main part packaging is not specified. Both substitute parts are supplied in tray packaging, which is standard for active production components.

Q: Why is 0760554103 listed as obsolete?

A: Product status reflects Molex's current manufacturing and support status. Active substitutes (0760555103, 0760557103) are available for new designs and ongoing production support.

Q: Are there any electrical differences between the three parts?

A: No. All three parts share identical voltage rating (30V), operating temperature range (-55°C ~ 85°C), contact finish (gold, 30.0µin), and flammability rating (UL94 V-0).
