Engineering Selection Recommendations

Primary Recommendation: Molex 0747503021

The 0747503021 is the manufacturer-recommended substitute for the obsolete 0747500021. Both parts share identical functional specifications within the 74750 series, including QSFP+ connector type, cage style, through-hole right-angle mounting, and press-fit termination.

The 0747503021 carries Active product status, ensuring long-term availability and continued manufacturer support. This part is suitable for new designs, production continuity, and field replacement applications where the original 0747500021 is no longer available.

Both parts maintain compliance with ROHS3 and carry EAR99 ECCN classification. The substitute part is supplied in Tray packaging, standard for production environments.

Frequently Asked Questions (FAQ)

Q: Can the 0747503021 directly replace the 0747500021 in existing designs?

A: Yes. Both parts are QSFP+ cage connectors with identical mounting type (through-hole, right-angle), termination method (press-fit), and mechanical features (EMI shielding, board lock). No PCB redesign is required.

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

A: The primary difference is product status. The 0747500021 is Obsolete, while the 0747503021 is Active. The 0747503021 is the current production equivalent and is recommended for all new applications and ongoing supply requirements.

Q: Are there packaging differences between these parts?

A: The 0747500021 packaging is not specified in the available data. The 0747503021 is supplied in Tray packaging, which is standard for production quantities and automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The 0747503021 MSL rating is listed as Not Applicable, which is typical for cage connectors that do not absorb moisture during storage.

Q: Which part should be selected for new designs?

A: The 0747503021 should be selected for all new designs. As the Active product with manufacturer recommendation, it ensures design longevity and supply chain continuity.
