PL56-12-130B Equivalent & Substitute Parts

Part Overview

The PL56-12-130B is a laminated core power transformer manufactured by Tamura with a rated power capacity of 56VA. This through-hole mounted component features dual primary and secondary windings, supporting input voltages of 115V or 230V with output configurations of parallel 6.3V at 8.8A or series 12.6V at 4.4A. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PL56-12-130B is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Power rating of 56VA
• Primary voltage support for both 115V and 230V
• Secondary voltage outputs of parallel 6.3V and series 12.6V
• Maximum output current of 8.8A (parallel) and 4.4A (series)
• Dual primary and dual secondary winding configuration
• Laminated core construction
• No center tap

Mechanical Equivalence Requirements:

• Through-hole mounting type
• PC pin termination style
• Length 76.20mm
• Width within 63.50mm to 64.00mm tolerance
• Height within 46.00mm to 48.50mm range

Compliance Considerations:

• ECCN classification EAR99
• HTSUS code alignment (8504.31.4035 or 8504.31.4065)

The identified substitute parts 14A-56-12 (Signal Transformer) and VPP12-4400 (Triad Magnetics) meet all electrical and mechanical equivalence criteria. Both substitutes are active products with enhanced isolation voltage ratings (4000Vrms) and RoHS3 compliance, providing improved reliability compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Existing Designs:

Both 14A-56-12 and VPP12-4400 are suitable direct replacements for PL56-12-130B applications. The substitutes provide identical electrical performance with enhanced isolation voltage (4000Vrms versus 3500Vrms), offering improved safety margins in high-voltage isolation applications.

Product Status Consideration:

The PL56-12-130B is classified as obsolete. The 14A-56-12 (Signal Transformer, One-4-All™ series) and VPP12-4400 (Triad Magnetics, PC Mount: World Series™) are both active products with current manufacturing support and documented availability.

Compliance and Certification:

Both substitute parts carry ROHS3 compliance and REACH unaffected status, meeting modern environmental and regulatory requirements. The main part does not specify these certifications. For applications requiring RoHS compliance, the substitute parts provide documented compliance assurance.

Mechanical Fit Verification:

The substitute parts feature slightly reduced height (46.00mm to 46.02mm versus 48.50mm) and width (63.50mm versus 64.00mm). These dimensional reductions remain within typical PCB layout tolerances for through-hole mounted transformers and do not impact electrical performance or mounting reliability.

Frequently Asked Questions (FAQ)

Q: Can 14A-56-12 and VPP12-4400 be used interchangeably with PL56-12-130B?

A: Yes. Both parts meet all electrical and mechanical equivalence criteria. They provide identical power ratings, voltage configurations, current outputs, and winding configurations. The through-hole PC pin termination and laminated core construction ensure direct compatibility.

Q: What is the significance of the higher isolation voltage in the substitute parts?

A: The substitute parts specify 4000Vrms isolation voltage compared to 3500Vrms in the main part. This represents a 500V increase in isolation capability, providing enhanced safety margins in applications requiring high-voltage isolation between primary and secondary circuits.

Q: Are there dimensional differences that affect PCB layout?

A: The substitute parts are slightly smaller in height (46.00-46.02mm versus 48.50mm) and width (63.50mm versus 64.00mm). These reductions are within standard tolerances for through-hole transformer mounting and do not require PCB redesign for direct replacement.

Q: What is the inventory status for each part?

A: PL56-12-130B has 951 pieces in stock (obsolete status). 14A-56-12 has 964 pieces available (active product). VPP12-4400 has 718 pieces available (active product). Active product status ensures ongoing availability for future procurement.

Q: Do the substitute parts meet current environmental standards?

A: Yes. Both 14A-56-12 and VPP12-4400 are ROHS3 compliant and REACH unaffected. The main part does not specify these certifications. For applications requiring documented environmental compliance, the substitute parts provide certified compliance.

Q: Are there any electrical performance differences between the three parts?

A: No. All three parts provide identical electrical specifications: 56VA power rating, dual 115V/230V primary inputs, dual 6.3V parallel or 12.6V series secondary outputs, and 8.8A parallel or 4.4A series maximum current. The substitute parts offer enhanced isolation voltage as an additional safety feature.
