API Delevan Inc. 6443-024 Equivalent & Substitute Parts

Part Overview

The API Delevan Inc. 6443-024 is a laminated core power transformer rated at 2.5VA with dual primary and secondary windings, designed for through-hole mounting applications. This transformer operates with selectable primary voltages (115V or 230V) and configurable secondary output (12V parallel or 24V series), delivering maximum output currents of 200mA (parallel) or 100mA (series). The part is classified as obsolete, necessitating identification of active substitute components that maintain equivalent electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6443-024 is based on equivalence across the following critical electrical and mechanical parameters:

Electrical Parameters: Power rating (2.5VA), primary voltage selection (115V/230V), secondary voltage configuration (12V parallel or 24V series), output current capacity (200mA parallel, 100mA series), isolation voltage (4000Vrms), and core type (laminated).

Mechanical Parameters: Through-hole mounting compatibility, PC pin termination, physical dimensions (34.93mm L x 28.58mm W x 30.15mm H maximum height), and weight class (0.25 lb).

The 6443R-024 qualifies as a direct substitute based on identical electrical specifications and mechanical form factor. The primary differentiation is product status (active versus obsolete) and RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 6443R-024 is the equivalent substitute for the obsolete 6443-024. Both components share identical electrical specifications (2.5VA power rating, dual primary/secondary windings, selectable voltage configurations) and mechanical form factors (through-hole mounting, PC pin termination, identical dimensions).

The primary advantage of selecting the 6443R-024 is active product status with RoHS3 compliance certification. The 6443-024, classified as obsolete, presents supply chain constraints and lacks RoHS3 compliance. For new designs or component replacement in systems requiring regulatory compliance, the 6443R-024 provides the appropriate substitute with guaranteed electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 6443-024 and 6443R-024 electrically interchangeable?

A: Yes. Both components provide identical electrical performance: 2.5VA power rating, dual primary windings (115V/230V selectable), dual secondary windings (12V parallel/24V series), and 4000Vrms isolation voltage. Output current capacity (200mA parallel, 100mA series) is identical across both parts.

Q: Do these transformers fit the same mounting footprint?

A: Yes. Both the 6443-024 and 6443R-024 feature identical through-hole mounting specifications, PC pin termination, and physical dimensions (34.93mm L x 28.58mm W x 30.15mm H maximum height). Direct mounting compatibility is confirmed.

Q: What is the difference between the 6443-024 and 6443R-024?

A: The 6443R-024 is the active production equivalent of the obsolete 6443-024. The substitute provides RoHS3 compliance certification, whereas the original part is RoHS non-compliant. Electrical performance and mechanical form factor are unchanged. Both components carry identical transformer specifications, isolation voltage rating, and winding configuration.

Q: Can the 6443-024 be used in designs requiring RoHS compliance?

A: No. The 6443-024 is RoHS non-compliant. Applications requiring RoHS3 certification must use the 6443R-024 substitute to satisfy regulatory requirements.

Q: Why is the 6443-024 marked as obsolete?

A: The 6443-024 has been discontinued by the manufacturer. The 6443R-024 has replaced this part number and remains in active production with improved compliance status. Original stock availability is limited; the substitute should be selected for ongoing designs and replacement applications.
