TAP600K10R Equivalent & Substitute Parts

Part Overview

The TAP600K10R is a 10 Ohms ±10% 600W thick film chassis mount resistor manufactured by Ohmite, part of the TAP600 series. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The TAP600K10R features M5 threaded leads, epoxy coating, and flanged mounting suitable for high-power applications requiring robust thermal management. Identification of compatible alternatives ensures design continuity and supply chain flexibility.

Substitute Part Grouping Explanation

Substitution for the TAP600K10R is determined by the following critical parameters: resistance value (10 Ohms), composition (thick film), mounting configuration (flanged M5 threaded leads), and thermal specifications (operating range -55°C to 150°C, temperature coefficient ±150ppm/°C).

Substitute parts are grouped into two categories:

Direct Equivalent: TAP600K10RE maintains identical electrical specifications (10 Ohms ±10%, 600W) and mechanical form factor. This part differs only in packaging (bulk vs. box) and product status (active vs. obsolete), making it a direct replacement.

Parametric Equivalent: TAP600J10RE and FPA350 10R J share the core resistance value (10 Ohms) and mounting interface (M5 threaded flanges) but differ in tolerance and/or power rating. TAP600J10RE provides 600W capacity with tighter tolerance (±5%). FPA350 10R J provides 350W capacity with ±5% tolerance, representing a reduced-power alternative suitable for applications not requiring full 600W dissipation.

Engineering Selection Recommendations

TAP600K10RE is the primary substitute for TAP600K10R. It provides identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. This part is recommended for direct replacement in all applications currently using TAP600K10R.

TAP600J10RE is suitable for applications where tighter tolerance (±5%) is beneficial and full 600W capacity is required. The improved tolerance specification may enhance circuit performance in precision applications. ROHS3 compliance and active status support long-term supply availability.

FPA350 10R J is applicable only to applications where power dissipation does not exceed 350W. This part offers tighter tolerance (±5%) and active product status but reduced power capacity. Selection of this part requires confirmation that circuit thermal requirements do not exceed 350W at the 10 Ohm load.

All three substitute parts maintain compatibility with the original M5 threaded flanged mounting interface and thermal operating range, ensuring mechanical and thermal interchangeability within their respective power ratings.

Frequently Asked Questions (FAQ)

Q: Can TAP600K10RE be used as a direct replacement for TAP600K10R?

A: Yes. TAP600K10RE provides identical resistance (10 Ohms), tolerance (±10%), power rating (600W), and mechanical form factor. The only differences are packaging format (bulk vs. box) and product status (active vs. obsolete). It is a direct functional equivalent.

Q: What is the difference between TAP600K10RE and TAP600J10RE?

A: Both parts share the same resistance (10 Ohms), power rating (600W), and mechanical interface. TAP600J10RE offers improved tolerance (±5% vs. ±10%). Selection depends on circuit tolerance requirements. Both are active products with ROHS3 compliance.

Q: When should FPA350 10R J be selected instead of TAP600K10RE?

A: FPA350 10R J is appropriate only when circuit power dissipation is confirmed to remain below 350W. This part offers tighter tolerance (±5%) but reduced power capacity. Applications requiring full 600W dissipation must use TAP600K10RE or TAP600J10RE.

Q: Are all substitute parts mechanically compatible with the original TAP600K10R?

A: Yes. All substitute parts feature M5 threaded leads with flanged mounting and identical seated height (1.280" / 32.50mm), ensuring mechanical interchangeability in the original mounting interface.

Q: What compliance advantages do the substitute parts offer?

A: TAP600K10RE, TAP600J10RE, and FPA350 10R J are all ROHS3 compliant, whereas TAP600K10R is non-compliant. For applications subject to RoHS regulations, substitute parts are required. All parts maintain REACH unaffected status and EAR99 ECCN classification.

Q: Are there inventory considerations for these substitutes?

A: TAP600K10RE (1244 pcs), TAP600J10RE (850 pcs), and FPA350 10R J (1157 pcs) are all in active stock. TAP600K10R (1013 pcs) is obsolete. For new designs or long-term supply assurance, active products are recommended.
