TAP600K22R Equivalent & Substitute Parts

Part Overview

The TAP600K22R is a 22 Ohms ±10% 600W thick film chassis mount resistor manufactured by Ohmite, part of the TAP600 series. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing system support and new design implementations. The TAP600K22R features M5 threaded leads, epoxy coating, and flanged mounting for high-power applications requiring robust thermal management in the -55°C to 150°C operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP600K22R is determined by strict alignment of the following critical parameters:

Direct Substitution Criteria:

• Resistance value: 22 Ohms
• Composition: Thick Film
• Mounting feature: Flanges
• Lead style: M5 Threaded
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -55°C to 150°C

Allowed Variation Parameters:

• Tolerance: May vary (±10% to ±5%)
• Power rating: May be equal or higher
• Packaging format: May differ (Box to Bulk)
• Product status: Active alternatives acceptable for obsolete parts
• RoHS compliance: May improve from non-compliant to compliant

Two substitute parts meet these criteria: TAP600K22RE (direct series continuation) and FPA350 22R J (parametric equivalent with reduced power rating).

Parameter Comparison

Engineering Selection Recommendations

TAP600K22RE is the primary substitute for TAP600K22R. Both parts are identical in electrical and mechanical specifications, with TAP600K22RE offering the advantage of active product status and ROHS3 compliance. The transition from Box to Bulk packaging does not affect functional compatibility. This substitute is suitable for direct replacement in all applications where the original TAP600K22R was specified.

FPA350 22R J serves as a parametric equivalent for applications where power dissipation requirements do not exceed 350W. This part provides improved tolerance (±5% versus ±10%) and maintains ROHS3 compliance. Selection of FPA350 22R J requires confirmation that the 350W power rating is sufficient for the intended circuit application, as it represents a 42% reduction from the original 600W specification.

Both substitutes maintain identical thermal characteristics, temperature coefficient, and operating range, ensuring thermal stability equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can TAP600K22RE be used as a direct replacement for TAP600K22R? A: Yes. TAP600K22RE is electrically and mechanically identical to TAP600K22R, with the advantage of active product status and improved RoHS compliance. No circuit modifications are required.

Q: What is the key difference between TAP600K22RE and FPA350 22R J? A: The primary difference is power rating: TAP600K22RE maintains 600W, while FPA350 22R J is rated at 350W. Both share identical resistance, tolerance options, temperature coefficient, and operating range. FPA350 22R J is suitable only for applications where power dissipation does not exceed 350W.

Q: Does the packaging change from Box to Bulk affect compatibility? A: No. Packaging format does not affect electrical or mechanical performance. The change from Box to Bulk packaging is a supply chain consideration only.

Q: Are there any compliance differences between the substitutes? A: Yes. TAP600K22R is RoHS non-compliant, while both TAP600K22RE and FPA350 22R J are ROHS3 compliant. This improvement may be required for new designs or systems subject to RoHS regulations.

Q: Can FPA350 22R J replace TAP600K22R in all applications? A: No. FPA350 22R J is suitable only for applications where the circuit power dissipation does not exceed 350W. Applications requiring the full 600W rating must use TAP600K22RE.

Q: What mounting considerations apply to these substitutes? A: All three parts feature identical M5 threaded leads, flanged mounting, and maximum seated height of 1.280" (32.50mm). No mechanical modifications to mounting hardware or PCB layout are required.
