FP230-25 Equivalent & Substitute Parts Reference

Part Overview

The FP230-25 is an active laminated core power transformer manufactured by Triad Magnetics, rated at 6VA with dual primary and secondary windings. This through-hole mounted component operates at 115V or 230V primary voltage with corresponding secondary outputs in parallel (120V, 50mA) or series (230V, 25mA) configurations. The part is ROHS3 compliant and maintains 2000Vrms isolation voltage. Equivalent substitute parts are identified for applications requiring alternative core construction, packaging formats, or inventory sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FP230-25 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Power rating: 6VA
• Primary voltage options: 115V and 230V dual configuration
• Secondary voltage outputs: Parallel 120V at 50mA maximum; Series 230V at 25mA maximum
• Dual primary and dual secondary winding architecture
• No center tap configuration

Mechanical Equivalence Requirements:

• Through-hole mounting type
• PC pin termination style
• Physical dimensions compatible with standard PCB footprints
• Height seated maximum within 22.23mm tolerance range

Compliance Requirements:

• ROHS3 compliance mandatory
• REACH unaffected status
• EAR99 export classification

The Hammond Manufacturing 229A230 qualifies as an equivalent substitute based on matching all electrical parameters, mounting configuration, termination style, and regulatory compliance status. The primary distinction is core construction type (semi-toroidal versus laminated) and secondary voltage parallel output specification (115V versus 120V).

Engineering Selection Recommendations

FP230-25 (Triad Magnetics) Selection Criteria:

• Applications requiring laminated core construction for specific electromagnetic performance characteristics
• Designs with PCB layout constraints accommodating 47.63mm length and 39.67mm width footprint
• Systems requiring 2000Vrms isolation voltage specification
• Flat Pack™ series component integration
• Box packaging for component handling and storage

229A230 (Hammond Manufacturing) Selection Criteria:

• Applications compatible with semi-toroidal core construction
• Designs with PCB layout constraints accommodating 39.62mm length and 47.75mm width footprint (rotated orientation possible)
• Systems where 1750Vrms isolation voltage meets application requirements
• Bulk packaging availability for high-volume procurement
• Weight-sensitive applications benefiting from 131.54g mass reduction

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for active product applications. Selection between these substitutes depends on PCB footprint availability, core construction performance requirements, and isolation voltage specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 229A230 directly replace the FP230-25 in existing PCB designs?

A: Direct PCB replacement requires footprint verification. The FP230-25 measures 47.63mm L × 39.67mm W, while the 229A230 measures 39.62mm L × 47.75mm W. Both share identical height (22.23mm and 21.59mm respectively) and through-hole PC pin termination. PCB layout modification or 90-degree component rotation may be necessary. Verify pad spacing and hole diameter compatibility before substitution.

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

A: The FP230-25 provides 120V parallel secondary output at 50mA maximum current. The 229A230 provides 115V parallel secondary output at 50mA maximum current. Both deliver 230V series secondary output at 25mA maximum. Applications requiring precise 120V output should specify the FP230-25. Applications tolerating ±5V variation can use either part.

Q: Does the isolation voltage difference affect substitution eligibility?

A: The FP230-25 provides 2000Vrms isolation; the 229A230 provides 1750Vrms isolation. Both exceed standard safety isolation requirements for low-voltage applications. Substitution is valid for applications where 1750Vrms isolation meets or exceeds design specifications. Applications with explicit 2000Vrms isolation requirements must use the FP230-25.

Q: What are the packaging implications for component procurement?

A: The FP230-25 is supplied in box packaging (738 pieces in stock). The 229A230 is supplied in bulk packaging (945 pieces in stock). Box packaging provides individual component protection; bulk packaging reduces per-unit cost for high-volume orders. Select packaging based on procurement volume and handling requirements.

Q: Are both parts suitable for automated assembly processes?

A: Both parts feature through-hole PC pin termination compatible with wave soldering and selective soldering processes. Verify component height clearance (22.23mm FP230-25; 21.59mm 229A230) against PCB assembly equipment specifications. Semi-toroidal core construction (229A230) may present different handling characteristics during automated placement compared to laminated core construction (FP230-25).

Q: What core construction differences exist between these parts?

A: The FP230-25 uses laminated core construction; the 229A230 uses semi-toroidal core construction. Laminated cores provide distributed flux paths suitable for standard transformer applications. Semi-toroidal cores offer improved efficiency and reduced electromagnetic interference in some applications. Core type selection depends on specific application electromagnetic performance requirements.
