Key Parameters

Substitute Part Grouping Explanation

The WNB5R0FE and WNB5R0FET are functionally equivalent wirewound resistors from the Ohmite WN series. Both parts share identical electrical specifications: 5 Ohm resistance, ±1% tolerance, 1W power rating, non-inductive wirewound construction, ±50ppm/°C temperature coefficient, and -55°C to 150°C operating range. The physical dimensions and axial package configuration are identical across both parts.

The substitution relationship is based on packaging format only. The WNB5R0FE is supplied in standard packaging, while the WNB5R0FET is supplied in Cut Tape (CT) format. Both maintain identical component specifications and are suitable for direct substitution in applications where the packaging format does not impose constraints on assembly or procurement workflows.

Parameter Comparison

Engineering Selection Recommendations

Both WNB5R0FE and WNB5R0FET 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 WNB5R0FET in Cut Tape format is suitable for automated pick-and-place assembly operations, while the WNB5R0FE in standard packaging accommodates manual assembly or bulk component handling. Both parts deliver identical electrical performance and thermal characteristics across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can WNB5R0FET replace WNB5R0FE in circuit applications? A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. WNB5R0FET uses Cut Tape packaging while WNB5R0FE uses standard packaging. Circuit performance is identical.

Q: What is the difference between standard packaging and Cut Tape (CT) format? A: Cut Tape format supplies components on continuous tape that is cut into individual pieces, optimized for automated assembly equipment. Standard packaging uses conventional bulk or reel formats. Electrical specifications remain unchanged.

Q: Are both parts RoHS compliant? A: Yes. Both WNB5R0FE and WNB5R0FET are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the temperature coefficient specification and why does it matter? A: Both parts have a temperature coefficient of ±50ppm/°C. This specifies the maximum resistance change per degree Celsius across the -55°C to 150°C operating range. This parameter is critical for precision applications requiring stable resistance values across temperature variations.

Q: Can these parts be used interchangeably in high-frequency applications? A: Both parts feature non-inductive wirewound construction, which minimizes inductance effects. Substitution is valid for applications where the non-inductive characteristic is required.
