• Core type: Laminated
• Primary winding configuration: Dual (115V, 230V)
• Secondary winding configuration: Dual (6.3V parallel / 12.6V series)
• Output current capacity: 1.6A parallel / 800mA series
• Isolation voltage: 4000Vrms
• Mounting type: Through Hole
• Termination style: PC Pin
• Physical dimensions: 47.63mm L x 39.67mm W x 36.50mm H (seated max)

The 6445R-012 qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 6445R-012 is the direct equivalent substitute for the obsolete 6445-012. Both parts maintain identical electrical performance and physical form factor, ensuring drop-in compatibility for through-hole PCB applications.

The primary distinction between the two parts is product status and regulatory compliance. The 6445-012 is obsolete and RoHS non-compliant, while the 6445R-012 is an active production part with ROHS3 compliance. For new designs or systems requiring regulatory adherence to RoHS3 standards, the 6445R-012 is the appropriate selection. For legacy system maintenance where the original 6445-012 is no longer available, the 6445R-012 provides full functional and mechanical equivalence.

Both parts share identical REACH and ECCN classifications, confirming regulatory parity across export and environmental compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can the 6445R-012 be used as a direct replacement for the 6445-012 in existing designs?

A: Yes. The 6445R-012 is electrically and mechanically identical to the 6445-012. All voltage ratings, current capacities, winding configurations, isolation specifications, and physical dimensions are equivalent. Through-hole mounting and PC pin termination are identical, enabling direct PCB substitution.

Q: What is the primary reason to transition from 6445-012 to 6445R-012?

A: The 6445-012 is classified as obsolete and is RoHS non-compliant. The 6445R-012 is an active production part with ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs and system updates.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts deliver 10VA power capacity with identical primary voltage options (115V, 230V), secondary voltage configurations (6.3V parallel / 12.6V series), output current ratings (1.6A parallel / 800mA series), and 4000Vrms isolation voltage.

Q: Do these transformers have the same physical footprint?

A: Yes. Both parts have identical dimensions of 47.63mm length x 39.67mm width with a maximum seated height of 36.50mm, and both weigh 0.53 lb (240.4 g). They are suitable for the same through-hole PCB layouts.

Q: What certifications apply to both parts?

A: Both parts share identical REACH and ECCN (EAR99) classifications. The 6445R-012 additionally carries ROHS3 compliance, while the 6445-012 is RoHS non-compliant.
