Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6443-012 is determined by strict equivalence across the following critical parameters:

• Power rating: 2.5VA
• Core type: Laminated
• Primary voltage configuration: Dual (115V/230V)
• Secondary voltage configuration: Dual (6.3V parallel / 12.6V series)
• Output current capacity: 400mA parallel / 200mA series
• Mounting type: Through hole
• Termination style: PC pin
• Isolation voltage: 4000Vrms
• Physical envelope: 34.93mm L × 28.58mm W × 30.15mm H maximum

The 6443R-012 meets all specified electrical and mechanical parameters and qualifies as a direct substitute based on identical functional specifications and form factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 6443R-012 is the direct equivalent substitute for the obsolete 6443-012. Both components share identical electrical specifications and mechanical form factors, ensuring pin-for-pin and footprint compatibility in existing circuit designs.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 6443-012 is obsolete and non-compliant with RoHS3 standards. The 6443R-012 is an active production part with ROHS3 compliance certification, making it the appropriate selection for new designs and ongoing system support where regulatory compliance is required.

Both parts maintain equivalent isolation voltage (4000Vrms), identical dimensional envelope, and matching termination specifications. No circuit redesign or board layout modification is required when transitioning from the 6443-012 to the 6443R-012.

Frequently Asked Questions (FAQ)

Q: Can the 6443R-012 be used as a direct replacement for the 6443-012 in existing designs?

A: Yes. The 6443R-012 is electrically and mechanically identical to the 6443-012. Both components feature the same power rating (2.5VA), voltage configurations, output current specifications, mounting type (through hole), termination style (PC pin), and physical dimensions. No circuit modifications are required.

Q: What is the difference between the 6443-012 and 6443R-012?

A: The primary differences are product status and regulatory compliance. The 6443-012 is obsolete and RoHS non-compliant. The 6443R-012 is an active production part with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with PCB footprints?

A: No. Both the 6443-012 and 6443R-012 share identical physical dimensions (34.93mm L × 28.58mm W × 30.15mm H maximum) and PC pin termination. PCB layouts designed for the 6443-012 require no modification to accommodate the 6443R-012.

Q: Does the 6443R-012 support the same voltage and current configurations?

A: Yes. The 6443R-012 provides identical primary voltage options (115V or 230V), secondary voltage configurations (6.3V parallel or 12.6V series), and maximum output current ratings (400mA parallel or 200mA series).

Q: What is the isolation voltage rating for both parts?

A: Both the 6443-012 and 6443R-012 are rated for 4000Vrms isolation voltage.

Q: Is RoHS3 compliance required for my application?

A: RoHS3 compliance is mandatory for products sold in the European Union and many other regulated markets. If your application requires regulatory compliance or future market access, the 6443R-012 is the appropriate selection. The 6443-012, being non-compliant, may face restrictions in certain jurisdictions.
