FP40-60 Equivalent & Substitute Parts Reference

Part Overview

The FP40-60 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 voltage with configurable secondary output of 20V parallel or 40V series. The transformer is designed for applications requiring isolated AC power conversion in compact form factors and is currently in active production status with 800 pieces in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across different core technologies and manufacturers while preserving functional requirements for the target application.

Substitute Part Grouping Explanation

Substitution eligibility for the FP40-60 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Primary voltage options must include both 115V and 230V
Secondary voltage configuration must support both 20V parallel and 40V series outputs
Maximum output current must meet or exceed 120mA parallel and 60mA series specifications
Dual primary and dual secondary winding architecture must be maintained
Voltage isolation rating must be sufficient for the application (minimum 1750Vrms acceptable)

Mechanical Equivalence Requirements:

Through-hole mounting type
PC pin termination style
Physical dimensions compatible with PCB layout constraints
Maximum seated height of 16.51mm or less

Compliance Requirements:

ROHS3 compliance mandatory
REACH unaffected status
Active product status

The substitute part 229E40 (Hammond Manufacturing) meets these criteria with the following considerations: core technology differs (semi-toroidal versus laminated), power rating is slightly lower (2VA versus 2.5VA), and isolation voltage is reduced (1750Vrms versus 2000Vrms). These variations remain within acceptable substitution parameters for applications not requiring the maximum power or isolation specifications of the primary part.

Engineering Selection Recommendations

Primary Part Selection (FP40-60): Select the FP40-60 when applications require the full 2.5VA power capacity and 2000Vrms isolation voltage rating. This laminated core design is suitable for standard industrial and commercial power conversion applications. ROHS3 compliance and active production status ensure long-term availability and regulatory conformance.

Substitute Part Selection (229E40): The 229E40 serves as a functional substitute for applications where power demand does not exceed 2VA and isolation voltage requirements are satisfied by 1750Vrms. The semi-toroidal core construction offers different electromagnetic characteristics compared to the laminated design. Both parts maintain identical electrical output specifications (20V/40V secondary, 120mA/60mA current capacity) and identical mechanical mounting interfaces. ROHS3 compliance and active production status are maintained.

Selection Criteria:

If maximum power capacity of 2.5VA is required, use FP40-60
If 2VA capacity is sufficient and cost optimization is a priority, 229E40 is acceptable
If 2000Vrms isolation is mandatory, use FP40-60
If 1750Vrms isolation is acceptable, 229E40 is acceptable
Both parts are suitable for through-hole PCB mounting with PC pin termination
Both parts meet current regulatory compliance requirements

Frequently Asked Questions (FAQ)

Q: Can the 229E40 be used as a direct replacement for the FP40-60 in all applications?

A: The 229E40 is functionally equivalent for applications requiring 2VA or less power delivery. If your application draws more than 2VA, the FP40-60 is required. If your application requires 2000Vrms isolation, the FP40-60 is required. For applications within 2VA and satisfied by 1750Vrms isolation, the 229E40 provides equivalent electrical performance with identical secondary voltage and current specifications.

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

A: The FP40-60 uses laminated core technology while the 229E40 uses semi-toroidal core technology. Both are established transformer core designs. The specific electromagnetic performance characteristics of each core type are not provided in the technical parameters. Selection between these technologies should be based on application-specific requirements not covered by the electrical and mechanical specifications listed.

Q: Are the physical dimensions compatible for PCB layout?

A: Both transformers have identical maximum seated height of 16.51mm. The FP40-60 measures 47.63mm L x 39.67mm W, while the 229E40 measures 39.62mm L x 47.75mm W. The footprint dimensions are transposed. Verify that your PCB layout can accommodate the 229E40 footprint orientation if substituting, as the length and width are reversed.

Q: Do both parts support the same primary voltage options?

A: Yes. Both the FP40-60 and 229E40 support dual primary voltage operation at 115V and 230V, with identical secondary voltage configurations of 20V parallel or 40V series.

Q: Are both parts RoHS compliant?

A: Yes. Both the FP40-60 and 229E40 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of the power rating difference (2.5VA vs 2VA)?

A: The FP40-60 is rated for maximum 2.5VA power delivery, while the 229E40 is rated for maximum 2VA. Both deliver identical maximum output currents (120mA parallel, 60mA series) at their respective secondary voltages. The power rating difference reflects the manufacturer's specification of maximum safe operating power. Applications requiring more than 2VA must use the FP40-60.

Q: Can I use the 229E40 if my application requires 2000Vrms isolation?

A: No. The 229E40 provides 1750Vrms isolation, which is 250Vrms lower than the FP40-60 specification of 2000Vrms. If your application requires 2000Vrms isolation, the FP40-60 must be used.
