TAP600K1R0 Equivalent & Substitute Parts

Part Overview

The TAP600K1R0 is a 1 Ohm ±10% 600W thick film chassis mount resistor manufactured by Ohmite, designed for high-power applications requiring robust thermal management and mechanical stability. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. The TAP600K1R0 features M5 threaded leads, epoxy coating, and flanged mounting for secure installation in chassis-based applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP600K1R0 is determined by the following critical parameters: resistance value (1 Ohm), composition (thick film), mounting configuration (M5 threaded flanges), operating temperature range (-55°C ~ 150°C), and temperature coefficient (±150ppm/°C). Substitute parts must maintain these core electrical and mechanical characteristics to ensure functional compatibility.

Two substitution categories are identified:

Direct Equivalent: TAP600K1R0E maintains identical specifications to the main part, including 1 Ohm resistance, ±10% tolerance, and 600W power rating. This part differs only in product status (active vs. obsolete) and RoHS compliance level.

Parametric Equivalents: TAP600J1R0E and FPA350 1R J provide functional alternatives with modified tolerance or power specifications. TAP600J1R0E maintains 600W power rating but reduces tolerance to ±5%. FPA350 1R J reduces power rating to 350W while improving tolerance to ±5%, representing a lower-power alternative for applications not requiring full 600W dissipation.

Parameter Comparison

Engineering Selection Recommendations

TAP600K1R0E is the primary substitute for the obsolete TAP600K1R0. This part is an active product with identical electrical and mechanical specifications, differing only in RoHS3 compliance status. Selection of TAP600K1R0E is appropriate for all applications currently using TAP600K1R0, with the added benefit of regulatory compliance for new designs and procurement cycles.

TAP600J1R0E serves as an alternative when improved tolerance (±5% vs. ±10%) is required while maintaining full 600W power capability and identical mechanical form factor. This part is suitable for applications with tighter resistance value requirements.

FPA350 1R J is applicable only for applications where power dissipation does not exceed 350W. This part offers improved tolerance (±5%) and active product status but represents a reduced-power alternative. Selection requires confirmation that thermal load requirements are met at 350W rating.

All three substitute parts maintain active product status and ROHS3 compliance, supporting long-term availability and regulatory requirements for modern designs.

Frequently Asked Questions (FAQ)

Q: Can TAP600K1R0E directly replace TAP600K1R0 in existing designs?

A: Yes. TAP600K1R0E maintains identical resistance (1 Ohm), tolerance (±10%), power rating (600W), temperature coefficient (±150ppm/°C), operating temperature range (-55°C ~ 150°C), and mechanical configuration (M5 threaded flanges, 65mm x 60mm footprint). The only differences are product status (active vs. obsolete) and RoHS compliance level.

Q: What is the difference between TAP600J1R0E and TAP600K1R0E?

A: Both parts share identical power rating (600W), mechanical form factor, and operating temperature range. TAP600J1R0E provides tighter tolerance (±5% vs. ±10%), making it suitable for applications requiring more precise resistance values. Electrical performance and thermal characteristics remain equivalent.

Q: When should FPA350 1R J be selected instead of TAP600K1R0E?

A: FPA350 1R J is appropriate only when application thermal requirements do not exceed 350W continuous dissipation. This part offers improved tolerance (±5%) and identical mechanical mounting, but reduced power capability. Thermal load analysis is required to confirm suitability.

Q: Are all substitute parts compatible with the same PCB layout and mechanical mounting?

A: Yes. All substitute parts maintain identical M5 threaded lead style, flanged mounting configuration, and seated height (1.280" / 32.50mm maximum). Mechanical compatibility is preserved across all substitutes.

Q: What compliance certifications apply to the substitute parts?

A: TAP600K1R0E, TAP600J1R0E, and FPA350 1R J are all ROHS3 compliant and REACH unaffected. All parts carry ECCN classification EAR99 and HTSUS code 8533.29.0000.
