Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WHC4R0FE is determined by matching the following critical parameters: resistance value (4 Ohms), tolerance (±1%), power rating (2W), composition (Wirewound), package type (Axial), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 150°C), and physical dimensions (0.180" Dia x 0.449" L). The WHC4R0FET qualifies as a direct substitute because it maintains all electrical and mechanical specifications while differing only in packaging configuration (Tape & Reel versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both WHC4R0FE and WHC4R0FET are Active status components manufactured by Ohmite with ROHS3 compliance. Selection between these parts is determined by packaging requirements: WHC4R0FE is supplied in standard packaging, while WHC4R0FET is supplied in Tape & Reel configuration. The Tape & Reel variant (WHC4R0FET) is suitable for automated assembly processes requiring continuous reel feeding. Both parts maintain identical electrical performance and physical dimensions, ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can WHC4R0FET replace WHC4R0FE in my circuit design? A: Yes. Both parts are electrically and mechanically identical, differing only in packaging format. The WHC4R0FET is supplied in Tape & Reel configuration while WHC4R0FE uses standard packaging.

Q: What is the primary difference between these substitute parts? A: The packaging configuration differs. WHC4R0FE is standard packaging; WHC4R0FET is Tape & Reel (TR). All electrical specifications, physical dimensions, and performance characteristics are identical.

Q: Are both parts ROHS3 compliant? A: Yes. Both WHC4R0FE and WHC4R0FET are ROHS3 compliant and maintain identical environmental compliance certifications.

Q: Which part should I select for automated assembly? A: WHC4R0FET (Tape & Reel configuration) is designed for automated pick-and-place assembly processes. WHC4R0FE (standard packaging) is suitable for manual assembly or bulk component handling.

Q: Do these parts have the same operating temperature range? A: Yes. Both parts operate across -55°C to 150°C with identical temperature coefficient specifications of ±50ppm/°C.
