Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6447-016 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Power rating: 30VA
• Primary voltage configuration: Dual 115V/230V
• Secondary voltage configuration: Parallel 8V or series 16V
• Secondary current capacity: Parallel 3.8A maximum, series 1.9A maximum
• Isolation voltage: 4000Vrms

Mechanical Parameters:

• Core type: Laminated
• Mounting configuration: Through hole
• Termination style: PC pin
• Physical envelope: 66.68mm L × 55.55mm W × 39.67mm H maximum

Compliance Parameters:

• ECCN classification: EAR99
• HTSUS code: 8504.31.4035

Parts meeting all these criteria are classified as direct substitutes. Variations in product status or compliance certifications do not affect functional equivalence when all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The 6447R-016 is a direct functional equivalent to the 6447-016. All electrical parameters, mechanical dimensions, and termination specifications are identical.

Product Status Consideration: The 6447-016 is classified as obsolete. The 6447R-016 carries active product status, indicating current manufacturing availability and ongoing supplier support.

Compliance Consideration: The 6447-016 is RoHS non-compliant. The 6447R-016 is ROHS3 compliant. For applications subject to RoHS directives or procurement policies requiring RoHS compliance, the 6447R-016 satisfies these requirements while maintaining full electrical and mechanical equivalence.

Both parts share identical ECCN (EAR99) and HTSUS (8504.31.4035) classifications, indicating no change in export control or tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 6447R-016 replace the 6447-016 in existing designs?

A: Yes. The 6447R-016 provides complete functional equivalence. All electrical parameters (power rating, voltage levels, current capacity, isolation voltage) and mechanical specifications (dimensions, mounting type, termination style) are identical.

Q: What is the difference between the 6447-016 and 6447R-016?

A: The primary differences are product status and RoHS compliance. The 6447-016 is obsolete and RoHS non-compliant. The 6447R-016 is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and manufacturing process, not electrical performance. Both transformers deliver identical electrical characteristics.

Q: Are the physical dimensions identical?

A: Yes. Both transformers measure 66.68mm L × 55.55mm W with a maximum seated height of 39.67mm. They are mechanically interchangeable in through-hole mounting applications.
