FP30-85 Equivalent & Substitute Parts Reference

Part Overview

The FP30-85 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 15V parallel or 30V series. The part maintains Active product status with full RoHS3 compliance and 2000Vrms isolation rating.

Substitute parts become necessary when primary sourcing is unavailable, when inventory constraints require alternative suppliers, or when design flexibility permits equivalent electrical and mechanical specifications. The FP30-85 has established equivalents that maintain functional compatibility within specified parameter tolerances.

• Power rating: 2.5VA nominal
• Isolation voltage: minimum 1500Vrms
• Dual primary and dual secondary winding configuration

Mechanical Compatibility Requirements:

• Mounting type: Through Hole
• Termination style: PC Pin
• Height seated: maximum 16.80mm
• Footprint dimensions: approximately 47-48mm length × 39-40mm width

Compliance Requirements:

• RoHS compliance (RoHS3 or equivalent)

The substitute parts 229E30 and 3FL30-85 satisfy these criteria with documented electrical equivalence and mechanical compatibility within specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

3FL30-85 (Tamura) - Primary Equivalent

The 3FL30-85 is the closest functional equivalent to the FP30-85. Both utilize laminated core construction and maintain identical voltage configurations with enhanced output current ratings (170mA parallel, 85mA series). The 3FL30-85 meets RoHS compliance requirements and maintains Active product status. Mechanical dimensions are nearly identical (47.60mm × 39.60mm versus 47.63mm × 39.67mm), with maximum seated height of 16.80mm. The isolation voltage of 1500Vrms is lower than the FP30-85 specification of 2000Vrms; this difference must be evaluated against application requirements. Inventory availability is substantial at 1563 pieces.

229E30 (Hammond Manufacturing) - Secondary Equivalent

The 229E30 provides electrical compatibility with dual primary and secondary windings configured for 15V parallel and 30V series operation. Output current ratings exceed FP30-85 specifications (170mA parallel, 85mA series). The semi-toroidal core construction differs from the laminated core design of the FP30-85. Mechanical footprint dimensions differ significantly: 39.62mm length × 47.75mm width represents a rotated orientation relative to the FP30-85. Isolation voltage is 1750Vrms. RoHS3 compliance and Active product status are confirmed. The 229E30 is suitable for applications where core type variation is acceptable and PCB layout permits the alternative footprint orientation.

Selection Criteria:

• Laminated core requirement: Select 3FL30-85
• Specific footprint constraint: Verify dimensional compatibility; 229E30 presents rotated orientation
• Isolation voltage requirement above 1750Vrms: FP30-85 is the only option meeting 2000Vrms specification
• Current capacity priority: Both 229E30 and 3FL30-85 exceed FP30-85 ratings
• Inventory urgency: 3FL30-85 offers highest stock level (1563 pieces)

All three parts maintain Active product status and full regulatory compliance for standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 3FL30-85 directly replace the FP30-85 in all applications?

A: The 3FL30-85 provides electrical equivalence for voltage and current specifications. The primary difference is isolation voltage: 1500Vrms versus 2000Vrms. Applications requiring 2000Vrms isolation must use the FP30-85. Mechanical dimensions are compatible within standard PCB tolerances. Verify isolation voltage requirements before substitution.

Q: What is the significance of the core type difference between FP30-85 (laminated) and 229E30 (semi-toroidal)?

A: Core type affects transformer efficiency, size, and thermal characteristics. Laminated cores (FP30-85, 3FL30-85) and semi-toroidal cores (229E30) have different magnetic properties. Both are suitable for 2.5VA and 2VA applications respectively. The choice depends on application-specific requirements for efficiency and thermal performance. Electrical output specifications remain equivalent.

Q: Are the footprint dimensions interchangeable between FP30-85 and 229E30?

A: No. The FP30-85 measures 47.63mm L × 39.67mm W, while the 229E30 measures 39.62mm L × 47.75mm W. The 229E30 represents a 90-degree rotated footprint. PCB layout must accommodate this orientation difference. Both maintain identical 16.51mm maximum seated height.

Q: What does the isolation voltage specification mean for substitution?

A: Isolation voltage (2000Vrms for FP30-85, 1500Vrms for 3FL30-85, 1750Vrms for 229E30) specifies the maximum voltage that can be safely applied between primary and secondary windings without breakdown. Applications requiring high isolation voltage must use the FP30-85. Standard industrial applications typically operate within 1500Vrms isolation capability.

Q: Are all three parts RoHS compliant?

A: Yes. FP30-85 and 229E30 are ROHS3 Compliant. The 3FL30-85 is RoHS Compliant. All three parts meet current environmental regulations and are suitable for applications requiring RoHS certification.

Q: What is the difference between the 160mA and 170mA output current ratings?

A: The FP30-85 is rated for 160mA maximum parallel output current. Both substitute parts (229E30 and 3FL30-85) are rated for 170mA. This 10mA difference represents approximately 6% higher capacity in the substitutes. Applications designed for 160mA operation are compatible with either substitute. Applications requiring exactly 160mA maximum should verify that the higher rating does not introduce design complications.

Q: Can I use the 229E30 if my application requires laminated core construction?

A: No. The 229E30 uses semi-toroidal core construction. If laminated core is a design requirement, select either FP30-85 or 3FL30-85.

Q: What packaging differences exist between these parts?

A: FP30-85 is supplied in Box packaging. Both 229E30 and 3FL30-85 are supplied in Bulk packaging. Packaging affects handling, storage, and minimum order quantities. Verify packaging requirements with procurement specifications.

Q: Are there any REACH or export compliance differences?

A: All three parts are REACH Unaffected and classified as ECCN EAR99 with HTSUS code 8504.31.4035. No compliance differences exist for standard commercial applications.
