PL30-28-130B Equivalent & Substitute Parts

Part Overview

The PL30-28-130B is a 30VA laminated core power transformer manufactured by Tamura, designed for through-hole mounting applications. This transformer features dual primary and secondary windings with selectable output configurations: parallel 14V at 2.12A or series 28V at 1.06A. The primary accepts 115V or 230V input, providing 3500Vrms isolation. The part is Active in product status and RoHS Compliant, with 1077 units currently in stock.

Substitute parts become necessary when the primary manufacturer's inventory is depleted, lead times exceed project requirements, or alternative sourcing strategies are implemented for supply chain resilience. The parts listed below maintain electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PL30-28-130B is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Power rating: 30VA
• Primary voltage inputs: 115V and 230V dual configuration
• Secondary voltage outputs: Parallel 14V and Series 28V
• Output current capacity: Parallel 2.12A and Series 1.06A
• Winding configuration: Dual primary and dual secondary
• Core type: Laminated
• Isolation voltage: Minimum 3500Vrms

Mechanical Equivalence Requirements:

• Mounting type: Through Hole
• Termination style: PC Pin
• Physical dimensions: Length 66.68–66.70mm, Width 55.50–55.60mm, Height 39.67–41.00mm
• Packaging: Bulk or Box

Compliance Requirements:

• RoHS compliance (RoHS3 or equivalent)
• ECCN: EAR99
• HTSUS: 8504.31.4035

Both substitute parts (14A-30-28 and VPP28-1060) meet all electrical and mechanical equivalence criteria and are Active in product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (PL30-28-130B): The PL30-28-130B remains the preferred selection when available. It is Active in product status, RoHS Compliant, and maintains the specified 3500Vrms isolation voltage. Current inventory of 1077 units supports immediate procurement.

Substitute Selection Criteria:

14A-30-28 (Signal Transformer): This substitute is electrically and mechanically equivalent to the PL30-28-130B. It is Active in product status and ROHS3 Compliant. The isolation voltage is rated at 4000Vrms, exceeding the primary part specification. Physical height is 1.30mm lower (39.70mm vs. 41.00mm), which may require PCB layout verification for clearance-critical applications. Inventory of 1449 units provides availability advantage.

VPP28-1060 (Triad Magnetics): This substitute is electrically and mechanically equivalent to the PL30-28-130B. It is Active in product status and ROHS3 Compliant. The isolation voltage is rated at 4000Vrms, exceeding the primary part specification. Physical dimensions are within 0.02mm of the primary part across all axes. Inventory of 1151 units supports procurement.

Both substitutes are suitable for direct replacement in applications where the primary part is unavailable. Selection between substitutes should be based on lead time, cost, and packaging requirements (Box vs. Bulk).

Frequently Asked Questions (FAQ)

Q: Can 14A-30-28 or VPP28-1060 be used as direct replacements for PL30-28-130B?

A: Yes. Both parts are electrically equivalent across all specified parameters: 30VA power rating, dual 115V/230V primary, dual 14V parallel / 28V series secondary, 2.12A parallel / 1.06A series output current, laminated core, dual windings, through-hole mounting, and PC pin termination. Both are Active in product status and RoHS compliant.

Q: What is the difference in isolation voltage between the main part and substitutes?

A: The PL30-28-130B specifies 3500Vrms isolation. Both substitutes (14A-30-28 and VPP28-1060) provide 4000Vrms isolation, which exceeds the requirement and presents no compatibility issue.

Q: Are there physical dimension differences that affect PCB layout?

A: The 14A-30-28 has a seated height of 39.70mm compared to the PL30-28-130B at 41.00mm, a difference of 1.30mm. The VPP28-1060 has a seated height of 39.67mm, a difference of 1.33mm. Length and width differences are negligible (≤0.02mm). PCB clearance verification is recommended for height-constrained designs.

Q: What are the packaging differences?

A: The PL30-28-130B is supplied in Bulk packaging. Both substitutes (14A-30-28 and VPP28-1060) are supplied in Box packaging. This affects receiving, storage, and handling procedures but does not affect electrical or mechanical compatibility.

Q: Are all three parts RoHS compliant?

A: Yes. The PL30-28-130B is RoHS Compliant. Both substitutes are ROHS3 Compliant, which represents a more recent compliance standard and is fully compatible with RoHS requirements.

Q: Which substitute should be selected if both are available?

A: Selection should be based on lead time, cost, and packaging requirements. Both 14A-30-28 and VPP28-1060 are electrically and mechanically equivalent. The VPP28-1060 has dimensions closer to the primary part (height difference of 1.33mm vs. 1.30mm for 14A-30-28), which may be preferable for space-constrained applications.
