Engineering Selection Recommendations

For Obsolete Part Replacement (6443-016): The 6443R-016 is the recommended direct substitute. Both components are manufactured by API Delevan Inc. and provide identical electrical performance and mechanical compatibility. The 6443R-016 offers the advantage of active production status, ensuring continued availability for future procurement cycles.

Regulatory Compliance Consideration: The primary distinction between these components is regulatory compliance. The 6443-016 is RoHS non-compliant, while the 6443R-016 is ROHS3 compliant. For applications subject to RoHS3 requirements or requiring long-term component availability, the 6443R-016 is the appropriate selection. Both components maintain REACH Unaffected status and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the 6443R-016 be used as a direct replacement for the 6443-016? A: Yes. The 6443R-016 is electrically and mechanically identical to the 6443-016. All electrical parameters (voltage, current, power rating, isolation) and mechanical specifications (dimensions, mounting type, termination style) are identical, enabling direct substitution in existing applications.

Q: What is the primary reason to select the 6443R-016 over the 6443-016? A: The 6443-016 is obsolete, making future procurement problematic. The 6443R-016 is active production, ensuring sustained availability. Additionally, the 6443R-016 is ROHS3 compliant, beneficial for applications requiring regulatory compliance.

Q: Are there any differences in physical mounting or PCB integration? A: No. Both components share identical physical dimensions (34.93mm L × 28.58mm W × 30.15mm H seated), mounting type (through-hole), and termination style (PC pin). PCB layouts designed for the 6443-016 require no modification for the 6443R-016.

Q: What are the key electrical parameters that define substitution eligibility? A: Critical parameters include 2.5VA power rating, 115V/230V primary voltage, 8V parallel / 16V series secondary voltage capability, 300mA parallel / 150mA series output current, and 4000Vrms isolation voltage. Any component lacking these specifications is not substitutable.

Q: Do both components have the same winding configuration? A: Yes. Both the 6443-016 and 6443R-016 feature dual primary windings and dual secondary windings, enabling identical voltage and current output configurations.
