WHB10RFET Equivalent & Substitute Parts

Part Overview

The WHB10RFET is a 10 Ohm ±1% 1W axial wirewound through-hole resistor manufactured by Ohmite, currently in active production status. This component is supplied in Tape & Reel packaging and is ROHS3 compliant. Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, and composition) and compatible mechanical form factors. Alternative models may be required due to packaging availability, inventory constraints, or specific compliance requirements for end applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WHB10RFET are qualified based on the following criteria:

Electrical equivalence is established through matching resistance value (10 Ohms), tolerance (±1%), power dissipation capability (1W), and composition type (wirewound). All substitute parts maintain the same axial through-hole form factor, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

The three identified substitute parts are:

41F10RE (Ohmite, Series 40) – Matches all electrical parameters with improved temperature coefficient (±20ppm/°C) and extended operating range (-55°C ~ 275°C). Supplied in Bulk packaging.

41F10R (Ohmite, Ohmicone® 40 Series) – Matches all electrical parameters with ±20ppm/°C temperature coefficient. Packaging type not specified.

RS01A10R00FE70 (Vishay Dale, RS Series) – Matches all electrical parameters with moisture-resistant construction, ±20ppm/°C temperature coefficient, and operating range of -65°C ~ 250°C. Supplied in Cut Tape packaging.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring ROHS3 compliance, the 41F10RE and RS01A10R00FE70 are the appropriate selections. The 41F10R is not suitable for RoHS-regulated applications due to non-compliant status.

The 41F10RE offers the widest operating temperature range (-55°C ~ 275°C) and improved temperature stability (±20ppm/°C) compared to the WHB10RFET, making it suitable for high-temperature environments. The RS01A10R00FE70 provides moisture-resistant construction with comparable temperature performance and ROHS3 compliance, with a slightly lower maximum operating temperature of 250°C.

Physical dimensions vary across the substitute parts. The WHB10RFET has the smallest diameter (0.130") and shortest length (0.276"), while the 41F10RE and 41F10R share identical dimensions (0.126" Dia x 0.437" L). The RS01A10R00FE70 has the smallest diameter (0.094") and intermediate length (0.406"). PCB layout compatibility must be verified when substituting, particularly for space-constrained applications.

Packaging format differs across alternatives: Tape & Reel for WHB10RFET, Bulk for 41F10RE, unspecified for 41F10R, and Cut Tape for RS01A10R00FE70. Selection should align with assembly process requirements and procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can the 41F10R be used as a direct substitute for the WHB10RFET?

A: The 41F10R matches all electrical parameters (10 Ohms, ±1%, 1W, wirewound) and physical form factor (axial). However, it is RoHS non-compliant, making it unsuitable for applications subject to RoHS regulations. Use only in applications where RoHS compliance is not required.

Q: What is the primary difference between the WHB10RFET and 41F10RE?

A: Both parts are manufactured by Ohmite and match all electrical specifications. The 41F10RE offers superior temperature stability (±20ppm/°C versus ±50ppm/°C) and an extended operating temperature range (-55°C ~ 275°C versus -55°C ~ 150°C). Physical dimensions differ slightly, with the 41F10RE being longer (0.437" versus 0.276").

Q: Is the RS01A10R00FE70 compatible with the WHB10RFET in terms of electrical performance?

A: Yes. The RS01A10R00FE70 matches the resistance value, tolerance, power rating, and composition. It provides equivalent or superior electrical performance with ±20ppm/°C temperature coefficient and moisture-resistant construction. Physical dimensions are smaller, which may be advantageous in space-constrained layouts.

Q: Are there any compliance differences between these parts?

A: The WHB10RFET and RS01A10R00FE70 are both ROHS3 compliant. The 41F10RE is RoHS compliant but not specifically ROHS3 certified. The 41F10R is RoHS non-compliant and should not be used in regulated applications.

Q: How do physical dimensions affect substitution?

A: All parts maintain the axial through-hole form factor and are mechanically compatible. However, dimensional variations may impact PCB layout fit. The WHB10RFET is the most compact (0.130" Dia x 0.276" L), while the 41F10RE and 41F10R are longer (0.437" L). The RS01A10R00FE70 offers a smaller diameter (0.094") with intermediate length (0.406"). Verify clearance in your specific application before substitution.

Q: Which substitute part offers the best temperature performance?

A: The 41F10RE provides the widest operating temperature range (-55°C ~ 275°C) and improved temperature coefficient (±20ppm/°C). The RS01A10R00FE70 offers comparable temperature stability with a maximum operating temperature of 250°C and includes moisture-resistant construction.
