Equivalent & Substitute Parts: PL10-20-130B

Part Overview

The PL10-20-130B is a laminated core power transformer manufactured by Tamura, rated for 10VA through-hole applications. This transformer features dual primary and secondary windings, supporting both parallel (10V, 1A) and series (20V, 500mA) output configurations with primary voltage options of 115V or 230V. The component is actively produced and RoHS compliant, making it suitable for industrial and commercial power supply designs requiring galvanic isolation at 3500Vrms.

Equivalent and substitute parts are identified when alternative manufacturers offer transformers with identical or functionally compatible electrical and mechanical specifications, enabling design flexibility, supply chain optimization, and inventory management without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility for the PL10-20-130B is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Power rating: 10VA
• Primary voltage options: 115V and 230V
• Secondary voltage outputs: Parallel 10V and Series 20V
• Output current capacity: Parallel 1A and Series 500mA
• Primary and secondary winding configuration: Dual windings
• Isolation voltage: Minimum 3500Vrms

Mechanical Equivalence Requirements:

• Core type: Laminated
• Mounting type: Through Hole
• Termination style: PC Pin
• Footprint dimensions: 47.60mm L × 39.70mm W
• Height seated maximum: Within acceptable tolerance for PCB assembly

Compliance Requirements:

• RoHS compliance status
• Active product status

The substitute part 14A-10R-20 manufactured by Signal Transformer meets all electrical and mechanical equivalence criteria, with enhanced isolation voltage (4000Vrms) and improved height specification (34.90mm), providing direct functional interchangeability in the PL10-20-130B application space.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (PL10-20-130B): The PL10-20-130B remains the baseline specification for new designs. It is actively manufactured by Tamura, RoHS compliant, and carries MSL 1 rating indicating unlimited shelf life stability. Current inventory of 1017 units supports immediate procurement.

Substitute Part Selection (14A-10R-20): The 14A-10R-20 from Signal Transformer is a direct functional equivalent suitable for applications where the PL10-20-130B is unavailable or where supply chain diversification is required. This substitute offers:

• Identical electrical performance across all primary and secondary configurations
• Enhanced isolation voltage (4000Vrms vs. 3500Vrms), providing additional safety margin
• Reduced seated height (34.90mm vs. 36.20mm), enabling tighter PCB layouts
• ROHS3 compliance, meeting current regulatory standards
• Higher inventory availability (2832 units)

Both parts share identical footprint dimensions (47.60mm L × 39.70mm W) and termination style (PC Pin through-hole), ensuring direct PCB compatibility without layout modification. The packaging difference (Tube vs. Box) affects only logistics and does not impact functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 14A-10R-20 be used as a direct replacement for the PL10-20-130B without circuit modification?

A: Yes. Both transformers are electrically and mechanically equivalent across all critical parameters: 10VA power rating, dual primary/secondary windings, 115V/230V primary input, 10V parallel and 20V series secondary outputs, 1A parallel and 500mA series current capacity, identical footprint, and PC Pin through-hole termination. No circuit redesign is required.

Q: What are the differences between these two parts?

A: The 14A-10R-20 provides three enhancements: (1) higher isolation voltage (4000Vrms vs. 3500Vrms), (2) lower seated height (34.90mm vs. 36.20mm), and (3) ROHS3 compliance versus RoHS compliance. These differences represent improvements that do not affect backward compatibility.

Q: Does the height difference affect PCB assembly?

A: No. The 14A-10R-20 has a lower seated height (34.90mm), which is compatible with any PCB design accommodating the PL10-20-130B (36.20mm). The reduced height provides additional clearance margin and may enable more compact enclosure designs.

Q: Are both parts currently in stock?

A: Yes. The PL10-20-130B has 1017 units in stock (Tube packaging), and the 14A-10R-20 has 2832 units in stock (Box packaging). Packaging format does not affect component performance.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable. The 14A-10R-20 offers enhanced isolation voltage and lower profile, making it suitable for applications requiring additional safety margin or compact layouts. The PL10-20-130B remains a valid choice where Tamura sourcing is preferred or existing supply agreements are in place.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant. The 14A-10R-20 carries ROHS3 certification, representing the current regulatory standard. Both parts carry EAR99 ECCN classification and share identical HTSUS code (8504.31.4035).

Q: Can these transformers be used in parallel or series configuration?

A: Yes. Both transformers support dual winding configurations enabling parallel output (10V, 1A) or series output (20V, 500mA) operation. Primary voltage selection (115V or 230V) is independent of secondary configuration.
