Substitute Part Grouping Explanation

Substitution eligibility for the WHC2K5FET is determined by equivalence across the following critical parameters:

• Resistance value: 2.5 kOhms
• Tolerance specification: ±1%
• Power rating: 2W
• Composition type: Wirewound
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C ~ 150°C
• Package configuration: Axial
• Physical dimensions: 0.180" Dia x 0.449" L (4.57mm x 11.40mm)
• Termination count: 2
• Regulatory compliance: ROHS3 Compliant

The WHC2K5FE qualifies as a direct substitute based on identical electrical and mechanical specifications. The distinction between these parts is limited to packaging format: WHC2K5FET is supplied in Cut Tape (CT) configuration, while WHC2K5FE is supplied in Bulk packaging. Both parts are manufactured by Ohmite within the WH series and maintain Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both WHC2K5FET and WHC2K5FE are Active status components manufactured by Ohmite with full ROHS3 compliance and REACH Unaffected designation. Selection between these parts is determined by packaging requirements and procurement logistics rather than electrical performance.

The WHC2K5FET in Cut Tape packaging is suitable for automated assembly processes and tape-and-reel handling systems. The WHC2K5FE in Bulk packaging accommodates manual assembly workflows and applications where tape packaging is not required. Both parts satisfy identical electrical specifications and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can WHC2K5FE replace WHC2K5FET in circuit applications?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Bulk). Circuit performance, reliability, and compliance characteristics are equivalent.

Q: What is the primary distinction between these substitute parts?

A: The WHC2K5FET is supplied in Cut Tape (CT) format for automated pick-and-place assembly, while WHC2K5FE is supplied in Bulk format. Electrical specifications, physical dimensions, and performance parameters are identical.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both WHC2K5FET and WHC2K5FE operate across -55°C to 150°C with identical temperature coefficient specifications of ±20ppm/°C.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8533.21.0080).

Q: Which part should be selected for high-volume automated assembly?

A: The WHC2K5FET in Cut Tape packaging is optimized for automated assembly processes. The WHC2K5FE in Bulk packaging is suitable for manual assembly or applications where tape format is not required.
