FP230-10 Equivalent & Substitute Parts Reference

Part Overview

The FP230-10 is an active 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 voltage with configurable secondary output (parallel 120V or series 230V). The transformer is designed for applications requiring isolated AC power conversion in compact form factors and is ROHS3 compliant with 2000Vrms isolation rating.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter tolerances for this product category, considering primary voltage, secondary voltage configuration, power rating, output current, winding configuration, mounting type, and isolation voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FP230-10 are identified based on strict electrical and mechanical compatibility within the allowed parameter set for laminated and semi-toroidal core power transformers. The substitution logic is based on the following criteria:

Primary Voltage Compatibility: Substitute must support 115V and 230V dual voltage primary operation.

Secondary Voltage Configuration: Substitute must provide parallel and series secondary winding configuration with output voltages compatible with 120V parallel and 230V series operation.

Power and Current Rating: Substitute power rating must be within acceptable range (2VA to 2.5VA); output current must support parallel 20mA and series 10mA operation.

Winding Configuration: Substitute must have dual primary and dual secondary windings to maintain voltage selection and output configuration flexibility.

Mounting and Termination: Substitute must use through-hole mounting with PC pin termination for direct PCB integration compatibility.

Isolation Voltage: Substitute isolation voltage must meet or exceed 1750Vrms minimum for safety compliance.

Regulatory Compliance: Substitute must maintain ROHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

FP230-10 (Primary Selection): Use when maximum power capacity (2.5VA) and highest isolation voltage (2000Vrms) are required. Laminated core construction provides established performance characteristics. ROHS3 compliance and active product status ensure long-term availability and regulatory support.

229E230 (Substitute Selection): Use when space constraints or specific footprint requirements favor semi-toroidal core design. Acceptable for applications where 2VA power rating is sufficient and parallel secondary voltage of 115V (versus 120V) is compatible with circuit design. Verify PCB layout accommodates reversed length and width dimensions (39.62mm L x 47.75mm W versus 47.63mm L x 39.67mm W). Lower isolation voltage (1750Vrms) remains compliant for standard industrial applications but provides reduced safety margin compared to FP230-10.

Substitution Feasibility: The 229E230 is electrically compatible as a substitute when the following conditions are met: (1) application load does not exceed 2VA; (2) parallel secondary voltage of 115V is acceptable in circuit design; (3) PCB footprint can accommodate reversed dimensions; (4) 1750Vrms isolation voltage meets application safety requirements.

Frequently Asked Questions (FAQ)

Q: Can the 229E230 directly replace the FP230-10 in existing designs?

A: Direct replacement requires verification of three factors: (1) PCB footprint compatibility—the 229E230 has reversed length and width dimensions (39.62mm L x 47.75mm W) compared to FP230-10 (47.63mm L x 39.67mm W); (2) parallel secondary voltage tolerance—229E230 outputs 115V parallel versus FP230-10's 120V parallel; (3) power budget—229E230 is rated 2VA versus FP230-10's 2.5VA. Height is identical at 16.51mm, so vertical clearance is not a constraint.

Q: What is the voltage difference between the parallel secondary outputs?

A: The FP230-10 provides 120V parallel secondary output, while the 229E230 provides 115V parallel secondary output. This 5V difference may be acceptable depending on circuit design tolerance. Series secondary output is identical at 230V for both transformers.

Q: Are both transformers ROHS3 compliant?

A: Yes, both FP230-10 and 229E230 are ROHS3 compliant and meet environmental regulatory requirements for electronic component manufacturing.

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

A: FP230-10 uses laminated core construction; 229E230 uses semi-toroidal core construction. Both are suitable for power conversion applications. Core type selection depends on specific application requirements for efficiency, size, and electromagnetic performance.

Q: Which transformer provides better isolation voltage?

A: FP230-10 provides 2000Vrms isolation voltage, while 229E230 provides 1750Vrms isolation voltage. FP230-10 offers a 250Vrms higher isolation margin, which may be preferred in applications requiring maximum safety clearance or operating in high-voltage environments.

Q: Can I use the 229E230 if my application requires 2.5VA power?

A: No. The 229E230 is rated at 2VA maximum power, which is 0.5VA below the FP230-10 rating. Applications requiring 2.5VA power capacity must use FP230-10 or equivalent higher-rated transformers.

Q: Are the output current ratings identical?

A: Yes, both transformers support identical maximum output current: 20mA in parallel configuration and 10mA in series configuration.

Q: What packaging differences exist between these transformers?

A: FP230-10 is supplied in box packaging; 229E230 is supplied in bulk packaging. This affects inventory management and component handling but does not impact electrical or mechanical compatibility.
