Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WHC330FE is determined by strict equivalence across the following critical parameters: resistance value (330 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, REACH unaffected). Packaging configuration variations (bulk versus cut tape) do not affect electrical or mechanical compatibility and therefore qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both WHC330FE and WHC330FET are Active status components with identical RoHS3 compliance and REACH unaffected designation. Selection between these parts is determined solely by packaging requirements: WHC330FE is supplied in bulk packaging, while WHC330FET is supplied in cut tape format. Both parts maintain full electrical and mechanical equivalence across all specified parameters and are suitable for direct substitution in circuit applications requiring 330 Ohm 2W axial wirewound resistors.

Frequently Asked Questions (FAQ)

Q: Can WHC330FET replace WHC330FE in production assembly? A: Yes. WHC330FET is a direct electrical and mechanical equivalent. The only difference is packaging format (cut tape versus bulk). Both parts are identical in resistance, tolerance, power rating, temperature characteristics, and physical dimensions.

Q: Does packaging format affect circuit performance? A: No. Packaging format (bulk or cut tape) does not affect electrical performance or mechanical fit. The resistor element and termination specifications are identical between WHC330FE and WHC330FET.

Q: Are both parts RoHS3 compliant? A: Yes. Both WHC330FE and WHC330FET are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the operating temperature range for these resistors? A: Both parts operate across -55°C to 150°C with a temperature coefficient of ±20ppm/°C, ensuring stable performance across industrial and commercial temperature environments.

Q: Are the physical dimensions identical? A: Yes. Both WHC330FE and WHC330FET share identical axial dimensions of 0.180" diameter by 0.449" length (4.57mm x 11.40mm), ensuring compatibility with existing PCB layouts and through-hole mounting patterns.
