FPA2K 15R K Equivalent & Substitute Parts

Part Overview

The FPA2K 15R K is a thick film power resistor manufactured by Ohmite, rated for 2000W at 15 Ohms with ±10% tolerance. This component is designed for chassis mount applications requiring high power dissipation in industrial and power electronics circuits. The part is currently Active in product status with 890 pieces in stock.

Substitute parts become necessary when application constraints require reduced power ratings, improved tolerance specifications, or alternative coating systems while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the FPA2K 15R K is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 15 Ohms
• Tolerance: ±10% or tighter
• Composition: Thick Film
• Temperature Coefficient: ±150ppm/°C
• Operating Temperature Range: -55°C to 150°C
• Mounting Feature: Flanges
• Lead Style: M5 Threaded
• Physical Dimensions: 2.559" L x 2.362" W x 1.280" H

Allowable Variation:

• Power Rating: Substitutes may have equal or lower power ratings
• Coating/Housing Type: Variations permitted (uncoated, epoxy coated)
• RoHS Compliance: ROHS3 or equivalent compliance required

The TAP800K15RE and TAP800J15RE both meet these substitution criteria with the primary difference being reduced power rating (800W versus 2000W) and coating system variations.

Engineering Selection Recommendations

FPA2K 15R K Selection Criteria: Select the FPA2K 15R K when applications require 2000W power dissipation at 15 Ohms with ±10% tolerance. This part maintains Active product status with ROHS3 compliance and is suitable for high-power industrial applications operating within the -55°C to 150°C temperature range.

TAP800K15RE Selection Criteria: The TAP800K15RE is suitable for applications requiring 800W power dissipation at 15 Ohms with ±10% tolerance. This substitute maintains identical electrical specifications and physical dimensions while providing epoxy coating for enhanced environmental protection. ROHS3 compliance is maintained.

TAP800J15RE Selection Criteria: The TAP800J15RE is suitable for applications requiring 800W power dissipation at 15 Ohms with improved ±5% tolerance. This substitute provides tighter tolerance specification than the main part while maintaining identical physical dimensions and operating temperature range. RoHS compliance is confirmed, though REACH status is vendor-undefined.

All three parts share identical mechanical mounting interfaces, thermal operating ranges, and temperature coefficient characteristics, ensuring direct substitution within power rating constraints.

Frequently Asked Questions (FAQ)

Q: Can TAP800K15RE or TAP800J15RE be used as direct replacements for FPA2K 15R K?

A: Direct substitution is possible only in applications where the 800W power rating is sufficient. The electrical characteristics (resistance, tolerance, temperature coefficient, operating range) and mechanical interfaces (M5 threaded leads, flange mounting, physical dimensions) are identical. Power dissipation requirements must be verified before substitution.

Q: What is the primary difference between TAP800K15RE and TAP800J15RE?

A: The TAP800J15RE provides ±5% tolerance compared to the ±10% tolerance of TAP800K15RE. Both parts share identical power ratings (800W), resistance (15 Ohms), and physical dimensions. Selection between these two depends on tolerance requirements of the application.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts feature identical physical dimensions (2.559" L x 2.362" W x 1.280" H), M5 threaded lead style, and flange mounting configuration. Mechanical installation is identical across all three part numbers.

Q: What compliance certifications apply to these parts?

A: FPA2K 15R K and TAP800K15RE are ROHS3 compliant. TAP800J15RE is RoHS compliant. All three parts are REACH Unaffected or Vendor Undefined. ECCN classification is EAR99 for all parts.

Q: Can FPA2K 15R K be substituted with TAP800 series parts in high-power applications?

A: No. The TAP800 series is rated for 800W maximum, while FPA2K 15R K is rated for 2000W. Substitution is only valid when application power requirements do not exceed 800W.

Q: What is the temperature coefficient specification for all three parts?

A: All three parts share an identical temperature coefficient of ±150ppm/°C across the operating temperature range of -55°C to 150°C.
