FP12-200 Equivalent & Substitute Parts Reference

Part Overview

The FP12-200 is a laminated core power transformer manufactured by Triad Magnetics, rated at 2.5VA with dual primary and secondary windings. This through-hole mounted component operates at 115V or 230V primary input with configurable secondary output of 6.3V parallel or 12.6V series. The part is Active status and ROHS3 compliant, making it suitable for industrial and commercial applications requiring regulated low-voltage power conversion.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative manufacturers while maintaining electrical and mechanical compatibility within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FP12-200 are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes maintain identical electrical specifications and mechanical form factors within acceptable tolerances. These parts satisfy all critical parameters: 2.5VA power rating, dual primary/secondary windings, 115V/230V primary input, 6.3V parallel and 12.6V series secondary output, 400mA parallel and 200mA series current capacity, through-hole mounting with PC pin termination, and laminated core construction.

Similar Substitutes provide equivalent electrical functionality with minor variations in non-critical parameters such as core type, isolation voltage, or dimensional tolerances. These parts maintain the same voltage ratings, current capacity, winding configuration, and mounting interface but may differ in physical dimensions or isolation specifications.

Substitution eligibility is determined by the following parameters:

• Power rating (2.5VA)
• Primary voltage configuration (115V, 230V dual)
• Secondary voltage configuration (6.3V parallel, 12.6V series)
• Output current capacity (400mA parallel, 200mA series)
• Winding configuration (dual primary, dual secondary)
• Mounting type (through hole)
• Termination style (PC pin)

Engineering Selection Recommendations

FP12-200-B (Direct Substitute)

The FP12-200-B is a direct substitute manufactured by Triad Magnetics in the Flat Pack™ series. This part is electrically and mechanically identical to the FP12-200, with identical dimensions (47.63mm L x 39.67mm W x 16.51mm H), isolation voltage (2000Vrms), and all electrical specifications. The only difference is packaging format: FP12-200-B is supplied in bulk packaging versus box packaging for the FP12-200. Both parts are ROHS3 compliant and Active status. Selection of FP12-200-B is appropriate when bulk packaging is acceptable and inventory availability is prioritized (660 units in stock).

3FL12-200 (Direct Substitute)

The 3FL12-200 manufactured by Tamura is a direct electrical substitute with identical voltage ratings, current capacity, winding configuration, and mounting interface. Dimensions are within acceptable tolerance (47.60mm L x 39.60mm W x 16.80mm H versus 47.63mm L x 39.67mm W x 16.51mm H). The isolation voltage is 1500Vrms compared to 2000Vrms for the FP12-200. This part is RoHS compliant and Active status. Selection of 3FL12-200 is appropriate when the reduced isolation voltage specification is acceptable for the application and higher inventory availability is required (2775 units in stock).

229E12 (Similar Substitute)

The 229E12 manufactured by Hammond Manufacturing provides equivalent electrical functionality with the same voltage ratings, current capacity, and winding configuration. This part differs in core type (semi-toroidal versus laminated), power rating (2.0VA versus 2.5VA), and isolation voltage (1750Vrms). Dimensional footprint differs (39.62mm L x 47.75mm W), requiring PCB layout verification. This part is ROHS3 compliant and Active status. Selection of 229E12 is appropriate when the semi-toroidal core type is acceptable, the 2.0VA rating is sufficient for the application, and dimensional differences can be accommodated in the design.

Frequently Asked Questions (FAQ)

Q: Can FP12-200-B be used as a direct replacement for FP12-200?

A: Yes. FP12-200-B is electrically and mechanically identical to FP12-200. The only difference is packaging format (bulk versus box). All electrical specifications, dimensions, isolation voltage, and compliance certifications are identical. Substitution is direct with no design modifications required.

Q: What is the key difference between 3FL12-200 and FP12-200?

A: The 3FL12-200 is electrically equivalent with identical voltage ratings, current capacity, and winding configuration. The primary differences are: (1) manufacturer (Tamura versus Triad Magnetics), (2) isolation voltage (1500Vrms versus 2000Vrms), and (3) dimensions within tolerance (47.60mm L x 39.60mm W x 16.80mm H versus 47.63mm L x 39.67mm W x 16.51mm H). Substitution is appropriate when the lower isolation voltage is acceptable for the application.

Q: Is 229E12 a suitable replacement for FP12-200?

A: 229E12 provides equivalent electrical functionality with identical voltage ratings and current capacity. However, it differs in three aspects: (1) core type (semi-toroidal versus laminated), (2) power rating (2.0VA versus 2.5VA), and (3) physical dimensions (39.62mm L x 47.75mm W versus 47.63mm L x 39.67mm W). Substitution is appropriate only when the semi-toroidal core type is acceptable, the 2.0VA rating is sufficient, and PCB layout can accommodate the different footprint.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) power rating (2.5VA or higher), (2) primary voltage configuration (115V/230V dual), (3) secondary voltage configuration (6.3V parallel and 12.6V series), (4) output current capacity (400mA parallel and 200mA series), (5) winding configuration (dual primary and dual secondary), (6) mounting type (through hole), and (7) termination style (PC pin). Variations in core type, isolation voltage, and dimensions within tolerance are acceptable for similar substitutes.

Q: Are all substitute parts RoHS compliant?

A: Yes. FP12-200, FP12-200-B, and 229E12 are ROHS3 compliant. The 3FL12-200 is RoHS compliant. All parts meet environmental compliance requirements for industrial applications.

Q: What inventory levels are available for each part?

A: FP12-200 has 670 units in stock (box packaging). FP12-200-B has 660 units in stock (bulk packaging). 3FL12-200 has 2775 units in stock (bulk packaging). 229E12 has 699 units in stock (bulk packaging). Inventory availability should be considered when selecting substitutes for time-sensitive applications.

Q: Can dimensions be used as a substitution criterion?

A: Dimensions are secondary criteria for substitution. All substitute parts maintain through-hole mounting and PC pin termination compatibility. Dimensional variations (within 0.1mm for length/width and 0.3mm for height) are acceptable for PCB layout purposes. The 229E12 has a different footprint orientation (39.62mm L x 47.75mm W) and requires PCB layout verification before substitution.
