Key Parameters

Substitute Part Grouping Explanation

The WHC250FE and WHC250FET are direct electrical and mechanical equivalents. Both components share identical resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, physical dimensions, and termination count. The substitution relationship is based strictly on these matching parameters. The sole difference between these parts is packaging format: WHC250FE is supplied in standard packaging, while WHC250FET is supplied in Tape & Reel (TR) configuration. This packaging distinction does not affect electrical performance or mechanical fit in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both WHC250FE and WHC250FET are Active status components with full RoHS3 compliance and REACH unaffected certification. Selection between these parts should be based on procurement and assembly requirements. The WHC250FE standard packaging format is suitable for manual assembly and small-volume applications. The WHC250FET Tape & Reel packaging is optimized for automated pick-and-place assembly and high-volume production environments. Both parts deliver identical electrical performance and mechanical compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can WHC250FET be used as a direct replacement for WHC250FE? A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. WHC250FET in Tape & Reel configuration can be used in any application where WHC250FE standard packaging is specified, provided assembly equipment supports tape-fed components.

Q: Does packaging format affect electrical performance? A: No. Packaging format is a supply and assembly consideration only. Both WHC250FE and WHC250FET deliver identical resistance value, tolerance, power rating, temperature coefficient, and operating temperature range.

Q: Are both parts suitable for high-temperature applications? A: Yes. Both WHC250FE and WHC250FET operate across -55°C to 150°C temperature range with ±20ppm/°C temperature coefficient, making them suitable for industrial and high-temperature circuit applications.

Q: What is the physical compatibility between these parts? A: Both parts are identical in physical dimensions: 0.180" diameter by 0.449" length (4.57mm x 11.40mm). They are mechanically interchangeable in through-hole PCB applications.

Q: Are both parts RoHS compliant? A: Yes. Both WHC250FE and WHC250FET are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
