WHCR10FE Equivalent & Substitute Parts

Part Overview

The WHCR10FE is a 100 mOhms ±1% 2W through-hole resistor manufactured by Ohmite in the WH series. This axial wirewound resistor is designed for applications requiring precision low-resistance values with stable performance across industrial temperature ranges. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified to provide alternative sourcing options while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WHCR10FE are qualified based on matching the following critical parameters:

• Resistance value: 100 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Composition: Wirewound
• Package type: Axial
• Temperature coefficient: ±90 ppm/°C
• Operating temperature range: -55°C to 150°C
• Physical dimensions: 0.180" Dia × 0.449" L
• Compliance certifications: RoHS3, REACH unaffected

The WHCR10FET qualifies as a direct substitute, differing only in packaging format (Cut Tape versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both WHCR10FE and WHCR10FET maintain Active product status with identical electrical and mechanical specifications. Selection between these parts depends on packaging and procurement requirements. The WHCR10FET in Cut Tape format provides alternative sourcing with higher inventory availability (4156 pcs versus 882 pcs). Both parts satisfy RoHS3 compliance and REACH unaffected requirements for regulated applications. No electrical performance differences exist between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Can WHCR10FET be used as a direct replacement for WHCR10FE?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, temperature coefficient, and operating range. The only difference is packaging format.

Q: What is the difference between standard packaging and Cut Tape (CT) packaging?

A: Cut Tape packaging indicates the component is supplied on tape that has been cut to length, typically for automated assembly processes. Standard packaging refers to the original supplier format. Both formats contain identical components.

Q: Are there any compliance differences between these parts?

A: No. Both WHCR10FE and WHCR10FET carry identical RoHS3 compliance and REACH unaffected status.

Q: What determines if a part can substitute for the WHCR10FE?

A: Substitute parts must match all electrical parameters (100 mOhms ±1%, 2W, ±90 ppm/°C), mechanical specifications (0.180" Dia × 0.449" L axial package), and compliance certifications (RoHS3, REACH unaffected).

Q: Can I mix WHCR10FE and WHCR10FET in the same assembly?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably in the same circuit or assembly without performance impact.
