API Delevan 6012-048 Laminated Power Transformer Equivalent & Substitute Parts

Part Overview

The API Delevan 6012-048 is a laminated core power transformer rated at 1.1VA with a 115V primary winding and dual secondary windings configured for parallel 24V or series 48V output. This through-hole mounted component features PC pin termination and 2500Vrms isolation voltage. The 6012-048 is classified as obsolete product status, necessitating identification of active equivalent alternatives to ensure continued design support and procurement availability for new production builds and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6012-048 is determined by strict equivalence across the following critical parameters: identical primary voltage (115V), matching secondary voltage configuration (parallel 24V and series 48V capability), equivalent secondary current ratings (parallel 46mA and series 23mA), laminated core construction, through-hole mounting, PC pin termination, and 2500Vrms isolation voltage. Physical dimensions, weight, and power rating must remain unchanged. The substitute part must originate from the same manufacturer (API Delevan Inc.) to ensure design compatibility and performance consistency. Product status and compliance certifications are secondary considerations that do not affect electrical or mechanical substitutability but influence procurement strategy and long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 6012R-048 is the direct active equivalent for the obsolete 6012-048. All electrical parameters, mechanical dimensions, and functional specifications are identical. The primary distinction is product status: the 6012R-048 is actively manufactured and supported, whereas the 6012-048 is obsolete and subject to inventory depletion.

For new designs and production builds, the 6012R-048 is the specified replacement. This part maintains full electrical and mechanical compatibility with existing PCB layouts and circuit designs originally developed for the 6012-048. No circuit modifications, board redesign, or functional revalidation is required.

The 6012R-048 achieves ROHS3 compliance, whereas the 6012-048 is non-compliant. Organizations subject to RoHS regulations or customer requirements mandating RoHS compliance must transition to the 6012R-048. For legacy systems or applications without RoHS requirements, either part functions identically from an electrical standpoint.

Current inventory status shows 828 units of the 6012R-048 available, providing adequate supply for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can the 6012R-048 be used as a direct replacement for the 6012-048 in existing designs?

A: Yes. The 6012R-048 is electrically and mechanically identical to the 6012-048. All electrical parameters, output voltages, current ratings, isolation voltage, and physical dimensions match exactly. No circuit modifications or PCB redesign is required. The component can be substituted directly into existing assemblies.

Q: What is the difference between the 6012-048 and 6012R-048?

A: The primary differences are product status and RoHS compliance. The 6012-048 is obsolete and RoHS non-compliant. The 6012R-048 is actively manufactured and ROHS3 compliant. Electrically and mechanically, both parts are identical.

Q: Why is the 6012-048 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The 6012R-048 is the active replacement in the product line. Existing 6012-048 inventory may be available from distributors, but long-term procurement cannot be guaranteed.

Q: Are there any compatibility concerns when switching from 6012-048 to 6012R-048?

A: No compatibility concerns exist. Both parts share identical electrical specifications, secondary voltage configurations (parallel 24V and series 48V), current ratings, isolation voltage, core type, mounting method, and termination style. PCB footprints and circuit behavior are identical.

Q: Does the 6012R-048 meet RoHS requirements?

A: Yes. The 6012R-048 is ROHS3 compliant. The 6012-048 is RoHS non-compliant. If your application or customer requirements mandate RoHS compliance, the 6012R-048 is the appropriate selection.

Q: What is the through-hole mounting configuration for these transformers?

A: Both the 6012-048 and 6012R-048 use PC pin termination for through-hole PCB mounting. Physical dimensions are 34.93mm length × 28.58mm width with a maximum seated height of 23.80mm.

Q: Can these transformers be configured for both 24V and 48V output simultaneously?

A: No. The dual secondary windings allow configuration as either parallel (24V at 46mA maximum) or series (48V at 23mA maximum), but not both simultaneously. Circuit design determines which configuration is used.
