PL20-10-130B Equivalent & Substitute Parts

Part Overview

The PL20-10-130B is a laminated core power transformer manufactured by Tamura, rated at 20VA with dual primary and secondary windings. This through-hole mounted component provides selectable output configurations: parallel 5V at 4A or series 10V at 2A, with primary voltage options of 115V or 230V. The part is classified as obsolete, necessitating identification of active equivalent components that maintain identical electrical and mechanical specifications for continued system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PL20-10-130B is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical power rating: 20VA
• Matching primary voltage options: 115V and 230V
• Matching secondary voltage outputs: parallel 5V and series 10V configurations
• Matching output current ratings: parallel 4A and series 2A
• Dual primary and dual secondary winding architecture
• Laminated core construction
• No center tap configuration

Mechanical Equivalence Requirements:

• Through-hole mounting type
• PC pin termination style
• Compatible dimensional envelope (length, width, height within tolerance)
• Isolation voltage rating of 3500Vrms minimum

Compliance Considerations:

• ECCN classification: EAR99
• HTSUS code: 8504.31.4035

The two identified substitute parts—Signal Transformer 14A-20-10 and Triad Magnetics VPP10-2000—satisfy all electrical and mechanical equivalence criteria. Both are active products with enhanced isolation voltage ratings (4000Vrms) and RoHS3 compliance, providing improved regulatory alignment compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Signal Transformer 14A-20-10

The 14A-20-10 is the direct functional equivalent of the PL20-10-130B. It maintains identical electrical specifications and mechanical form factor while offering active product status and RoHS3 compliance. The marginal increase in isolation voltage (4000Vrms versus 3500Vrms) provides enhanced safety margin without affecting circuit compatibility. This part is suitable for direct replacement in existing designs and new implementations requiring the One-4-All™ series designation.

Secondary Recommendation: Triad Magnetics VPP10-2000

The VPP10-2000 provides equivalent electrical performance with dimensional compatibility within acceptable tolerance. The World Series™ designation indicates this component is optimized for PC mount applications. Like the 14A-20-10, it offers active status and RoHS3 compliance with 4000Vrms isolation voltage. Selection between the two substitutes depends on supply chain availability, packaging preference (bulk versus box), and series-specific design requirements.

Compliance Advantage:

Both substitute parts provide RoHS3 compliance and REACH unaffected status, addressing regulatory requirements that may not have been applicable to the obsolete PL20-10-130B. This compliance enhancement supports long-term product lifecycle management and market access across regulated regions.

Frequently Asked Questions (FAQ)

Q: Can the 14A-20-10 or VPP10-2000 be used as direct replacements for the PL20-10-130B in existing circuit boards?

A: Yes. Both substitute parts maintain identical electrical specifications (20VA, dual primary/secondary windings, 115V/230V primary, 5V/10V secondary outputs, 4A/2A current ratings) and compatible mechanical form factors (through-hole mounting, PC pin termination, equivalent dimensions and height). No circuit modifications are required.

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

A: The substitute parts provide 4000Vrms isolation voltage compared to the main part's 3500Vrms. This represents an enhanced safety margin and does not affect circuit compatibility. Higher isolation voltage is a beneficial characteristic that improves component robustness without introducing any negative effects.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 14A-20-10 is supplied in bulk packaging, while the VPP10-2000 is supplied in box packaging. This distinction affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Q: Why is the PL20-10-130B classified as obsolete?

A: The PL20-10-130B is no longer in active production. The identified substitute parts (14A-20-10 and VPP10-2000) are active products that provide equivalent functionality with improved compliance certifications, making them the recommended alternatives for ongoing system support and new designs.

Q: Do the substitute parts have the same dimensional footprint?

A: The substitute parts have dimensions within acceptable tolerance of the main part. The 14A-20-10 matches the PL20-10-130B exactly at 57.20mm L x 47.60mm W. The VPP10-2000 measures 57.15mm L x 47.63mm W, representing a negligible variation of 0.05mm in length and 0.03mm in width. Height specifications are equivalent (41.28mm to 41.30mm). These tolerances are within standard PCB design margins and do not require layout modifications.

Q: What certifications do the substitute parts carry?

A: Both substitute parts are RoHS3 compliant and REACH unaffected. They maintain the same ECCN (EAR99) and HTSUS (8504.31.4035) classifications as the main part, ensuring consistent regulatory and trade compliance.
