Engineering Selection Recommendations

PL56-10-130B (Tamura) is the primary specification. Selection of this part is appropriate when:

Original design validation has been completed with this specific manufacturer part
Existing inventory of 833 units is available for immediate procurement
RoHS Compliant certification meets application requirements

VPP10-5600 (Triad Magnetics) is an electrical and mechanical equivalent. This substitute is appropriate when:

PL56-10-130B availability is constrained
Higher isolation voltage (4000Vrms vs. 3500Vrms) provides additional safety margin
ROHS3 Compliant certification meets or exceeds application requirements
Lower profile height (46.02mm vs. 48.50mm) accommodates space constraints
Inventory of 1030 units provides supply continuity
PCB layout accommodates the 0.5mm width reduction (63.50mm vs. 64.00mm)

Both parts share identical electrical performance across all specified operating parameters and are functionally interchangeable in applications designed for the PL56-10-130B specification.

Frequently Asked Questions (FAQ)

Q: What makes VPP10-5600 a valid substitute for PL56-10-130B?

A: The VPP10-5600 matches all critical electrical parameters: 56VA power rating, dual 115V/230V primary windings, dual secondary windings with 5V parallel and 10V series configurations, and identical output current ratings of 11.2A parallel and 5.6A series. Mechanical compatibility is confirmed through identical mounting type (through-hole), termination style (PC pin), and equivalent physical dimensions. Both parts maintain EAR99 ECCN classification and RoHS compliance.

Q: Are there dimensional differences between these parts?

A: Yes. The VPP10-5600 has a 0.5mm narrower width (63.50mm vs. 64.00mm) and is 2.48mm lower in seated height (46.02mm vs. 48.50mm). The length is identical at 76.20mm. These differences are within typical PCB layout tolerances for through-hole mounted transformers and do not affect electrical compatibility.

Q: Does the higher isolation voltage of VPP10-5600 affect compatibility?

A: No. The VPP10-5600 isolation voltage of 4000Vrms exceeds the PL56-10-130B specification of 3500Vrms. This represents an enhancement and does not create compatibility issues. Applications designed for 3500Vrms isolation operate safely with the higher-rated substitute.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with Restriction of Hazardous Substances directives. ROHS3 represents the current version of the RoHS 2 directive (2011/65/EU as amended). Both are acceptable for applications requiring RoHS compliance. The VPP10-5600 ROHS3 Compliant status meets or exceeds requirements for the PL56-10-130B RoHS Compliant specification.

Q: Can I use VPP10-5600 in an existing design validated with PL56-10-130B?

A: Yes, provided the PCB layout accommodates the dimensional variations. The 0.5mm width reduction and 2.48mm height reduction of the VPP10-5600 are typically compatible with existing through-hole footprints. Verify that the narrower width does not create clearance issues with adjacent components and that the lower profile does not conflict with enclosure constraints.

Q: What is the inventory status for each part?

A: PL56-10-130B has 833 units in stock. VPP10-5600 has 1030 units in stock. Both parts are listed as Active in production status.
