VPS12-10300 Equivalent & Substitute Parts

Part Overview

The VPS12-10300 is a laminated core power transformer manufactured by Triad Magnetics, rated at 130VA with dual primary and secondary windings. This chassis mount transformer is designed for applications requiring 115V or 230V primary input with selectable secondary output configurations (parallel 6.3V or series 12.6V). The part is currently active in production with ROHS3 compliance and is suitable for industrial and commercial equipment applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when packaging requirements differ.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VPS12-10300 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Power rating: 130VA
• Primary voltage options: 115V, 230V
• Secondary voltage configuration: Parallel 6.3V, Series 12.6V
• Core type: Laminated
• Mounting: Chassis Mount
• Winding configuration: Dual primary, dual secondary
• Isolation voltage: 4000Vrms
• Compliance: ROHS3, REACH Unaffected

Secondary Considerations:

• Termination style compatibility (Solder, Quick Connect)
• Physical dimensions within tolerance
• Weight specifications
• Packaging format (Box or Bulk)

The VPS12-10300-B (Triad Magnetics) qualifies as a direct substitute with identical electrical specifications and differs only in packaging (Bulk vs. Box). The A41-130-12 (Signal Transformer) qualifies as a functional substitute with equivalent primary specifications but exhibits reduced secondary current output capacity in both parallel and series configurations.

Parameter Comparison

Engineering Selection Recommendations

VPS12-10300-B Selection Criteria: The VPS12-10300-B is electrically and mechanically identical to the VPS12-10300. Selection of this variant is appropriate when bulk packaging is acceptable for manufacturing or inventory management. Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected) and are produced by the same manufacturer. Dimensional specifications are identical, ensuring direct mechanical compatibility in existing designs.

A41-130-12 Selection Criteria: The A41-130-12 qualifies as a functional substitute when secondary current capacity reduction is acceptable within the application design. This part maintains equivalent primary voltage specifications, isolation voltage, and core type. The reduced secondary current output (20.6A parallel, 10.3A series versus 26A parallel, 13A series) requires verification that the application load does not exceed these limits. All compliance certifications (ROHS3, REACH Unaffected) are equivalent. Dimensional variation in width (76.20mm versus 68.33mm) requires mechanical clearance verification in the target application.

Compliance and Status: All three parts are active products with current manufacturing status. All maintain ROHS3 compliance and REACH Unaffected status, suitable for applications with environmental regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can VPS12-10300-B be used as a direct replacement for VPS12-10300? A: Yes. The VPS12-10300-B is electrically and mechanically identical to the VPS12-10300. The only difference is packaging format (Bulk versus Box). Both parts are manufactured by Triad Magnetics with identical electrical specifications, dimensions, and compliance certifications.

Q: What is the key limitation when substituting A41-130-12 for VPS12-10300? A: The A41-130-12 has reduced secondary current capacity: 20.6A in parallel configuration and 10.3A in series configuration, compared to 26A and 13A respectively for the VPS12-10300. Applications requiring maximum secondary current output must not exceed these limits. Additionally, the A41-130-12 is 7.87mm wider (76.20mm versus 68.33mm), requiring mechanical clearance verification.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The VPS12-10300, VPS12-10300-B, and A41-130-12 are all ROHS3 compliant and REACH Unaffected, meeting environmental regulatory requirements for industrial and commercial applications.

Q: What is the difference between the VPS12-10300 and VPS12-10300-B packaging? A: The VPS12-10300 is supplied in Box packaging, while the VPS12-10300-B is supplied in Bulk packaging. Electrical and mechanical specifications are identical. Selection depends on inventory management and manufacturing process requirements.

Q: Can the A41-130-12 be used in applications requiring 26A secondary current output? A: No. The A41-130-12 maximum secondary current output is 20.6A in parallel configuration, which is below the 26A specification of the VPS12-10300. Applications requiring 26A output must use VPS12-10300 or VPS12-10300-B.

Q: Are the physical dimensions compatible across all three parts? A: The VPS12-10300 and VPS12-10300-B have identical dimensions (71.37mm L × 68.33mm W × 85.85mm H). The A41-130-12 has a width of 76.20mm, which is 7.87mm wider. Mechanical clearance verification is required before substitution in space-constrained applications.

Q: Do all parts support both 115V and 230V primary input? A: Yes. All three parts (VPS12-10300, VPS12-10300-B, and A41-130-12) support dual primary voltage operation at 115V or 230V, with selectable secondary output configurations (parallel 6.3V or series 12.6V).
