WHCR50FE Equivalent & Substitute Parts

Part Overview

The WHCR50FE is a 500 mOhms ±1% 2W axial wirewound through-hole resistor manufactured by Ohmite. This component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Equivalent and substitute parts are identified when applications require alternative packaging formats, procurement availability, or specific feature requirements while maintaining identical electrical performance and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the WHCR50FE are qualified based on matching the following critical parameters: resistance value (500 mOhms), tolerance (±1%), power rating (2W), composition (wirewound), package type (axial), temperature coefficient (±90ppm/°C), operating temperature range (-55°C to 150°C), physical dimensions (0.180" Dia x 0.449" L), and compliance certifications (RoHS3, REACH unaffected). Substitutes are differentiated by packaging format (Cut Tape versus Bulk) and construction features (standard wirewound versus non-inductive wirewound). All qualified substitutes maintain electrical equivalence and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with identical electrical specifications and full regulatory compliance. Selection between WHCR50FE, WHCR50FET, and WNCR50FE is determined by packaging and procurement requirements. WHCR50FET in Cut Tape format is suitable for automated assembly processes. WNCR50FE in Bulk packaging is appropriate for high-volume applications where non-inductive characteristics are specified. All parts are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing.

Frequently Asked Questions (FAQ)

Q: Can WHCR50FET be used as a direct replacement for WHCR50FE? A: Yes. WHCR50FET is electrically and mechanically equivalent to WHCR50FE. The difference is packaging format: WHCR50FET is supplied in Cut Tape (CT) format while WHCR50FE uses standard packaging. Both maintain identical electrical performance and physical dimensions.

Q: What is the difference between WHCR50FE and WNCR50FE? A: Both parts share identical electrical specifications (500 mOhms, ±1%, 2W, ±90ppm/°C, -55°C to 150°C). The primary difference is construction: WNCR50FE is a non-inductive wirewound resistor from the WN series, while WHCR50FE is a standard wirewound resistor from the WH series. WNCR50FE is supplied in Bulk packaging format.

Q: Are all three parts suitable for the same circuit applications? A: Yes, provided the application does not specifically require non-inductive characteristics. If inductance is a design constraint, WNCR50FE is the appropriate selection. For standard applications, all three parts are functionally interchangeable.

Q: Do packaging format differences affect electrical performance? A: No. Packaging format (standard, Cut Tape, or Bulk) affects procurement and assembly processes only. Electrical specifications and performance remain identical across all three parts.

Q: Are these parts compliant with current environmental regulations? A: Yes. All three parts are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
