FP88-65 Equivalent & Substitute Parts Reference

Part Overview

The FP88-65 is a 6VA laminated core power transformer manufactured by Triad Magnetics, designed for through-hole mounting applications. This transformer features dual primary and secondary windings with selectable voltage configurations (115V or 230V primary input; 44V parallel or 88V series secondary output). The part is currently in active production status with 753 units in stock inventory.

Equivalent and substitute parts are identified when they maintain identical electrical performance specifications while potentially offering different core construction, packaging, or physical dimensions. Substitution becomes necessary when the primary part is unavailable, when alternative packaging formats are required, or when design revisions call for different form factors within the same electrical performance envelope.

Key Parameters

Substitute Part Grouping Explanation

The FP88-65 and 229A88 are classified as electrical equivalents based on the following matching parameters:

Matching Electrical Specifications:

• Power rating: 6VA
• Primary voltage inputs: 115V, 230V (both options available)
• Secondary voltage outputs: 44V parallel, 88V series
• Maximum output current: 130mA parallel, 65mA series
• Winding configuration: Dual primary, dual secondary
• Center tap: None
• Mounting type: Through hole
• Termination style: PC pin
• Regulatory compliance: ROHS3 compliant, REACH unaffected, EAR99 classification

Differing Specifications:

• Core construction: FP88-65 uses laminated core; 229A88 uses semi-toroidal core
• Isolation voltage: FP88-65 rated 2000Vrms; 229A88 rated 1750Vrms
• Physical dimensions: Different length and width; similar height
• Weight: FP88-65 weighs 0.438 lb; 229A88 weighs 0.29 lb
• Packaging: FP88-65 supplied in box; 229A88 supplied in bulk
• Inventory source: Different manufacturers (Triad Magnetics vs. Hammond Manufacturing)

Substitution is valid when the application requirements do not mandate the higher isolation voltage specification of the FP88-65 and when physical space constraints permit the different dimensional profile of the 229A88.

Parameter Comparison

Engineering Selection Recommendations

FP88-65 (Triad Magnetics - Laminated Core)

Select the FP88-65 when:

• Application requires 2000Vrms isolation voltage specification
• Laminated core construction is specified in design documentation
• Box packaging format is required for inventory management
• Original equipment manufacturer (OEM) part continuity is required
• Current inventory availability (753 units) meets procurement timeline

229A88 (Hammond Manufacturing - Semi-Toroidal Core)

Select the 229A88 when:

• 1750Vrms isolation voltage meets application requirements
• Semi-toroidal core construction is acceptable or preferred
• Reduced weight (0.29 lb vs. 0.438 lb) is advantageous for the application
• Bulk packaging format is compatible with assembly processes
• Dimensional profile (39.62mm L × 47.75mm W) fits available PCB space
• Current inventory availability (767 units) supports procurement needs

Both parts maintain identical electrical performance for the 6VA power rating, dual winding configurations, and voltage/current specifications. Both are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these equivalents depends on isolation voltage requirements, core type preference, physical space constraints, and packaging format compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 229A88 directly replace the FP88-65 in all applications?

A: Direct replacement is valid when the application does not require the 2000Vrms isolation voltage specification of the FP88-65. The 229A88 provides 1750Vrms isolation. Both parts deliver identical electrical performance for power rating, voltage outputs, and current capacity. Physical dimensions differ; verify PCB layout compatibility before substitution.

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

A: The FP88-65 uses laminated core construction; the 229A88 uses semi-toroidal core construction. Both core types are suitable for 6VA power transformers. Core type selection affects weight, physical dimensions, and electromagnetic characteristics. The provided specifications do not include detailed electromagnetic performance data; consult manufacturer datasheets for core-specific performance curves if required.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry identical regulatory status. No compliance barriers exist for substitution from a regulatory perspective.

Q: What packaging differences exist between FP88-65 and 229A88?

A: The FP88-65 is supplied in box packaging; the 229A88 is supplied in bulk packaging. Box packaging typically includes individual part protection and documentation. Bulk packaging reduces per-unit cost and is suitable for high-volume assembly operations. Verify that bulk packaging meets your receiving, storage, and handling requirements.

Q: How do the physical dimensions affect substitution?

A: FP88-65 dimensions are 47.63mm L × 39.67mm W × 22.23mm H (seated). 229A88 dimensions are 39.62mm L × 47.75mm W × 21.59mm H (seated). The parts have swapped length and width dimensions. Verify that the 229A88 footprint fits your PCB layout and that no mechanical interference occurs with adjacent components. Height difference is minimal (0.64mm).

Q: What is the weight difference and does it matter?

A: FP88-65 weighs 0.438 lb (198.67 g); 229A88 weighs 0.29 lb (131.54 g). The 229A88 is approximately 33% lighter. Weight difference is relevant for applications with strict weight budgets or where vibration isolation is critical. For most stationary electronic equipment, this difference is not significant.

Q: Can I use the 229A88 in high-voltage isolation applications?

A: The 229A88 provides 1750Vrms isolation voltage. If your application requires 2000Vrms isolation, the 229A88 does not meet the specification. Verify isolation voltage requirements in your application design documentation before selecting the 229A88 as a substitute.

Q: Are both parts currently available?

A: Yes. FP88-65 inventory: 753 units in stock. 229A88 inventory: 767 units in stock. Both parts are active production items from their respective manufacturers. Verify current availability with your component supplier for your specific procurement timeline.
