FP88-130 Equivalent & Substitute Parts Reference

Part Overview

The FP88-130 is a 12VA laminated core power transformer manufactured by Triad Magnetics, designed for through-hole mounting applications. This transformer features dual primary and secondary windings with selectable voltage configurations (115V/230V primary input; 44V parallel or 88V series secondary output). The part is currently in active production status with ROHS3 compliance and maintains robust inventory availability of 726 pieces.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved within the specified parameter tolerances for this transformer category.

Engineering Selection Recommendations

FP88-130 (Triad Magnetics - Laminated Core):

Primary selection for applications requiring 2000Vrms isolation voltage specification
Laminated core construction provides established performance characteristics
Active production status with 726-piece inventory availability
Flat Pack™ series designation indicates optimized form factor

229B88 (Hammond Manufacturing - Semi-Toroidal):

Functionally equivalent for applications with 1750Vrms isolation voltage requirement
Semi-toroidal core construction offers alternative electromagnetic performance profile
Active production status with 830-piece inventory availability
Bulk packaging option available
Dimensions: 50.80mm L x 63.50mm W (note: length and width reversed relative to FP88-130)

Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts depends on isolation voltage requirements and available PCB layout space for the dimensional orientation.

Frequently Asked Questions (FAQ)

Q: Can the 229B88 directly replace the FP88-130 in all applications?

A: The 229B88 provides electrical equivalence for all voltage, current, and winding specifications. However, the isolation voltage differs (1750Vrms vs. 2000Vrms). Applications requiring the full 2000Vrms isolation specification must use the FP88-130. Additionally, the semi-toroidal core construction differs from the laminated core, which may affect electromagnetic performance in specific circuit topologies.

Q: Are the physical dimensions compatible for PCB mounting?

A: Both parts use through-hole mounting with PC pin termination. The FP88-130 dimensions are 63.50mm L x 50.80mm W x 26.97mm height. The 229B88 dimensions are 50.80mm L x 63.50mm W x 27.18mm height. The length and width are transposed. PCB layout must accommodate the specific orientation of the selected part.

Q: What is the difference between laminated and semi-toroidal core construction?

A: This information is provided as a specification difference only. Both core types are qualified for this 12VA power transformer application with the electrical parameters specified.

Q: Are both parts currently available?

A: Yes. The FP88-130 has 726 pieces in stock (box packaging). The 229B88 has 830 pieces in stock (bulk packaging).

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Both maintain the same HTSUS code: 8504.31.4035.
