WHC2R0FET Equivalent & Substitute Parts

Part Overview

The WHC2R0FET is a 2 Ohm ±1% 2W through-hole resistor manufactured by Ohmite in the WH series. This axial wirewound resistor is designed for applications requiring precision resistance with moderate power dissipation in a compact form factor. The part maintains Active product status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WHC2R0FET is determined by matching the following critical parameters:

• Resistance value: 2 Ohms
• Tolerance: ±1%
• Power rating: 2W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 150°C
• Physical dimensions: 0.180" Dia x 0.449" L
• Regulatory compliance: RoHS3 Compliant, REACH Unaffected

The WNC2R0FET qualifies as a parametric equivalent based on identical electrical specifications and mechanical compatibility. Packaging format differs (Cut Tape vs. Tape & Reel), which affects supply chain logistics but does not impact functional performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both WHC2R0FET and WNC2R0FET maintain Active product status with identical regulatory compliance certifications. Selection between these parts is determined by packaging and supply chain requirements rather than electrical or mechanical performance criteria.

The WHC2R0FET in Tape & Reel format is suitable for high-volume automated assembly operations. The WNC2R0FET in Cut Tape format accommodates lower-volume applications or manual assembly workflows. Both parts satisfy identical circuit performance requirements and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can WNC2R0FET replace WHC2R0FET in circuit applications?

A: Yes. Both parts are parametric equivalents with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Electrical and thermal performance in the circuit are equivalent.

Q: What is the difference between these parts?

A: The primary difference is packaging format. WHC2R0FET is supplied in Tape & Reel (TR) configuration for automated pick-and-place assembly. WNC2R0FET is supplied in Cut Tape (CT) configuration. The WNC2R0FET also features non-inductive construction, which may provide performance advantages in high-frequency applications, though this specification is not a limiting factor for standard circuit substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both WHC2R0FET and WNC2R0FET are ROHS3 Compliant and REACH Unaffected.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts measure 0.180" Dia x 0.449" L (4.57mm x 11.40mm) and use identical axial package configuration. PCB footprint and mounting requirements are identical.

Q: Which part should I select for new designs?

A: Selection depends on manufacturing volume and assembly method. For high-volume automated assembly, WHC2R0FET (Tape & Reel) is standard. For lower-volume or manual assembly, WNC2R0FET (Cut Tape) is appropriate. Both parts are Active and equally suitable for new designs.
