API Delevan 6445-036 Equivalent & Substitute Parts

Part Overview

The API Delevan 6445-036 is a 10VA laminated core power transformer with dual primary and secondary windings, designed for through-hole mounting applications. This component features selectable voltage configurations (115V or 230V primary input) with parallel or series secondary output options (18V parallel / 36V series). The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the API Delevan 6445-036 requires matching of critical electrical and mechanical parameters that define functional equivalence in power transformer applications. The following parameters establish the substitution criteria:

Electrical Parameters:

• Power rating: 10VA
• Primary voltage configuration: Dual winding supporting 115V and 230V selection
• Secondary voltage output: Dual winding configuration with 18V (parallel) and 36V (series) capability
• Output current capacity: 560mA (parallel) and 280mA (series)
• Isolation voltage: 4000Vrms minimum

Mechanical Parameters:

• Mounting type: Through hole
• Termination style: PC pin
• Physical dimensions: Compatible with 47.63mm L x 39.67mm W footprint and 36.50mm maximum seated height
• Core type: Laminated construction

Compliance Considerations:

• Product status: Obsolete components may require substitutes with improved compliance profiles
• RoHS status: Original component is RoHS non-compliant; substitute availability may include RoHS-compliant alternatives

No substitute parts have been provided in the input data. Equivalent components must satisfy all electrical parameters listed above while maintaining mechanical compatibility with the original through-hole PC pin mounting configuration.

Parameter Comparison

No substitute parts are available for comparison at this time. When substitute components are identified, comparison will include alignment of power rating, voltage configurations, current ratings, isolation voltage, mounting type, termination style, and physical dimensions.

Engineering Selection Recommendations

Selection of substitute components for the obsolete API Delevan 6445-036 must prioritize electrical parameter matching: 10VA power rating, dual primary winding (115V/230V), dual secondary winding (18V parallel / 36V series), and 4000Vrms isolation voltage. Mechanical compatibility is mandatory, requiring through-hole mounting with PC pin termination and dimensional fit within the specified envelope.

For applications where RoHS compliance is a system requirement, substitute components with RoHS-compliant certification should be prioritized, provided all electrical and mechanical specifications remain equivalent.

Frequently Asked Questions (FAQ)

Q: What makes a transformer a valid substitute for the 6445-036? A: A valid substitute must provide 10VA power rating, support dual primary windings for 115V and 230V operation, deliver dual secondary windings with 18V parallel and 36V series output, maintain 4000Vrms isolation voltage, and use through-hole PC pin mounting with compatible physical dimensions (47.63mm L x 39.67mm W x 36.50mm H max).

Q: Can transformers with different power ratings substitute for the 6445-036? A: No. The 10VA power rating is a critical specification. Substitutes with higher or lower power ratings will not provide equivalent performance and may cause circuit malfunction or component damage.

Q: Is RoHS compliance required for substitution? A: RoHS compliance is not a substitution requirement unless specified by the application or system design. The original 6445-036 is RoHS non-compliant. However, RoHS-compliant alternatives may be preferred for new designs or systems with environmental compliance mandates.

Q: Can a transformer with a single secondary winding substitute for the dual secondary design? A: No. The dual secondary winding configuration enabling both 18V parallel and 36V series operation is a functional requirement. Single secondary designs cannot replicate this capability.

Q: What is the significance of the 4000Vrms isolation voltage specification? A: The 4000Vrms isolation rating defines the maximum voltage differential that can be safely applied between primary and secondary circuits. Substitutes must meet or exceed this specification to maintain electrical safety and circuit protection.

Q: Are there dimensional constraints for mounting? A: Yes. The through-hole PC pin termination and physical envelope (47.63mm L x 39.67mm W x 36.50mm H max) are fixed by PCB layout. Substitute components must fit within these constraints to ensure mechanical compatibility and proper circuit board integration.
