Substitute Part Grouping Explanation

Substitute parts for the WHC470FET are identified through parametric equivalence. The substitution criteria are based on the following electrical and mechanical parameters:

• Resistance value: 470 Ohms
• Tolerance: ±1%
• Power rating: 2W
• Composition: Wirewound
• Non-inductive feature requirement
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 150°C
• Package configuration: Axial through-hole
• Physical dimensions: 0.180" Dia × 0.449" L
• Number of terminations: 2
• Packaging format: Tape & Reel

The WNC470FET from Ohmite meets all specified electrical and mechanical parameters, making it a parametric equivalent suitable for direct substitution in applications requiring the WHC470FET.

Parameter Comparison

Engineering Selection Recommendations

Both the WHC470FET and WNC470FET are active products from Ohmite with identical electrical and mechanical specifications. The WNC470FET offers additional compliance documentation with RoHS certification and defined moisture sensitivity level (MSL 1), providing enhanced traceability for regulated applications. Selection between these parts should be based on inventory availability and compliance requirements specific to the end application. Both parts are suitable for direct substitution where the specified electrical parameters and axial through-hole package configuration are required.

Frequently Asked Questions (FAQ)

Q: Can the WNC470FET replace the WHC470FET in existing designs?

A: Yes. Both parts share identical resistance (470 Ohms), tolerance (±1%), power rating (2W), temperature coefficient (±20ppm/°C), operating temperature range (-55°C to 150°C), and physical dimensions (0.180" Dia × 0.449" L). The axial package configuration and non-inductive wirewound composition are identical, enabling direct substitution.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by matching resistance value, tolerance, power rating, composition type, temperature coefficient, operating temperature range, package configuration, and physical dimensions. All these parameters are identical between the WHC470FET and WNC470FET.

Q: Are there any compliance differences between these parts?

A: The WNC470FET carries RoHS Compliant certification and specifies Moisture Sensitivity Level 1 (Unlimited). The WHC470FET does not specify these certifications. For applications requiring RoHS compliance or moisture sensitivity documentation, the WNC470FET is the appropriate selection.

Q: Do these parts have the same packaging format?

A: Yes. Both the WHC470FET and WNC470FET are supplied in Tape & Reel (TR) packaging, ensuring compatibility with automated assembly processes and identical handling requirements.

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, providing stable performance across industrial and commercial temperature environments.
