WHC15RFE Equivalent & Substitute Parts

Part Overview

The WHC15RFE is a 15 Ohm ±1% 2W axial wirewound through-hole resistor manufactured by Ohmite. This component is classified as Active product status and is designed for applications requiring precision resistance with moderate power dissipation in through-hole configurations. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WHC15RFE are identified based on strict equivalence across the following critical parameters: resistance value (15 Ohms), tolerance (±1%), power rating (2W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), operating temperature range (-55°C to 150°C), physical dimensions (0.180" Dia x 0.449" L), and regulatory compliance (ROHS3 Compliant, REACH Unaffected). Parts meeting all these specifications are classified as direct substitutes. Packaging format differences (such as Cut Tape versus standard packaging) do not affect electrical or mechanical compatibility and represent alternative supply chain options.

Parameter Comparison

Engineering Selection Recommendations

The WHC15RFET is a direct electrical and mechanical equivalent to the WHC15RFE. Both components are manufactured by Ohmite, share identical electrical specifications, and maintain full compliance with ROHS3 and REACH requirements. Selection between these parts should be based on packaging and supply chain requirements. The WHC15RFE is available in standard packaging format, while the WHC15RFET is supplied in Cut Tape format. Both are Active status products suitable for production applications.

Frequently Asked Questions (FAQ)

Q: Can WHC15RFET be used as a direct replacement for WHC15RFE in PCB assembly?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. WHC15RFET arrives in Cut Tape format, which is compatible with automated pick-and-place equipment. WHC15RFE uses standard packaging. Both mount identically on PCBs.

Q: Are there any performance differences between WHC15RFE and WHC15RFET?

A: No. Both parts have identical electrical characteristics: 15 Ohm resistance, ±1% tolerance, 2W power rating, ±20ppm/°C temperature coefficient, and -55°C to 150°C operating range.

Q: What does the "T" designation in WHC15RFET indicate?

A: The "T" suffix indicates Cut Tape packaging format, which is a supply chain variant. This does not affect component performance or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both WHC15RFE and WHC15RFET are ROHS3 Compliant and REACH Unaffected.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the full -55°C to 150°C temperature range with identical temperature coefficient specifications.
