API Delevan 6444-012 Equivalent & Substitute Parts

Part Overview

The API Delevan 6444-012 is a laminated core power transformer rated at 5VA with dual primary and secondary windings. This through-hole mounted component provides selectable output configurations through parallel (6.3V, 800mA) or series (12.6V, 400mA) winding connections. The transformer features 4000Vrms isolation voltage and PC pin termination for direct PCB integration.

The 6444-012 carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute components must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6444-012 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitute relationships:

Electrical Equivalence Requirements:

• Identical power rating (5VA)
• Matching primary voltage options (115V, 230V)
• Identical secondary voltage outputs in both parallel (6.3V) and series (12.6V) configurations
• Matching output current specifications (800mA parallel, 400mA series)
• Equivalent isolation voltage (4000Vrms)
• Identical winding configuration (dual primary, dual secondary, no center tap)

Mechanical Equivalence Requirements:

• Laminated core construction
• Through-hole mounting compatibility
• PC pin termination style
• Identical physical dimensions (41.28mm L × 33.32mm W × 33.32mm H)
• Equivalent weight tolerance

Compliance Considerations:

• Product status transition from obsolete to active
• RoHS compliance status
• REACH and ECCN classifications

The 6444R-012 meets all electrical and mechanical equivalence criteria and qualifies as a direct substitute for the 6444-012.

Parameter Comparison

Engineering Selection Recommendations

The 6444R-012 is the direct equivalent substitute for the obsolete 6444-012. Both components share identical electrical specifications and mechanical form factors, enabling direct PCB replacement without circuit modification.

Selection Basis:

The 6444R-012 maintains full functional equivalence across all critical parameters: 5VA power rating, dual primary/secondary winding configuration, selectable output voltages (6.3V parallel or 12.6V series), matching current ratings (800mA and 400mA respectively), and identical 4000Vrms isolation voltage. Physical dimensions and through-hole PC pin termination are unchanged, ensuring compatibility with existing PCB layouts and assembly processes.

Compliance Advantage:

The 6444R-012 carries active product status with RoHS3 compliance certification, addressing regulatory requirements for new production and long-term supply chain stability. The original 6444-012, classified as obsolete and RoHS non-compliant, presents supply discontinuity risk and regulatory exposure in applications subject to RoHS directives.

Inventory and Availability:

Current stock of 880 units of the 6444R-012 supports immediate procurement for production requirements. The 6444-012 remains available with 1079 units in inventory but should be reserved for legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can the 6444R-012 replace the 6444-012 in existing designs without modification?

A: Yes. The 6444R-012 is electrically and mechanically identical to the 6444-012. All electrical parameters (voltage, current, power rating, isolation) and physical dimensions match exactly. Direct substitution on PCBs is possible without circuit redesign or layout changes.

Q: What is the difference between the 6444-012 and 6444R-012?

A: The primary differences are product status and regulatory compliance. The 6444-012 is obsolete and RoHS non-compliant. The 6444R-012 is an active product with RoHS3 compliance. All electrical and mechanical specifications are identical.

Q: Why should I transition from 6444-012 to 6444R-012?

A: The 6444-012 is classified as obsolete, creating long-term supply uncertainty. The 6444R-012 is an active product with confirmed availability and RoHS3 compliance, supporting regulatory requirements in markets with RoHS mandates. Transitioning to the 6444R-012 ensures design continuity and compliance.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the 6444-012 and 6444R-012 measure 41.28mm length × 33.32mm width × 33.32mm height and weigh 0.37 lb (167.83 g). Through-hole mounting and PC pin termination are identical, ensuring PCB compatibility.

Q: Can I use the 6444R-012 in parallel or series winding configuration?

A: Yes. The 6444R-012 supports both configurations identically to the 6444-012. Parallel connection delivers 6.3V at 800mA. Series connection delivers 12.6V at 400mA. Winding configuration is determined by external circuit connections, not the component itself.

Q: What is the isolation voltage rating?

A: Both the 6444-012 and 6444R-012 provide 4000Vrms isolation voltage between primary and secondary windings.

Q: Is the 6444R-012 suitable for new product designs?

A: Yes. The 6444R-012 is an active product with RoHS3 compliance and is appropriate for new designs requiring a 5VA laminated core transformer with dual primary/secondary windings and through-hole mounting.

Q: What certifications apply to the 6444R-012?

A: The 6444R-012 carries RoHS3 compliance certification. Both parts are classified as REACH Unaffected and carry EAR99 ECCN designation.
