Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UB5C-10RF8 is determined by the following critical parameters:

Resistance value must be 10 Ohms with ±1% tolerance to maintain circuit accuracy. Power rating must be 5W to ensure thermal performance under specified load conditions. Composition must be wirewound to preserve the electrical characteristics required for current sensing applications. Package type must be axial to ensure mechanical compatibility with through-hole PCB layouts. Temperature coefficient of ±50ppm/°C establishes the thermal stability requirement. RoHS3 compliance and REACH unaffected status are mandatory for regulatory conformance.

The WHE10RFET from Ohmite meets all critical electrical and mechanical substitution criteria. Operating temperature range differences do not preclude substitution when the application operates within the overlapping temperature window of -55°C ~ 150°C.

Parameter Comparison

Engineering Selection Recommendations

Both the UB5C-10RF8 and WHE10RFET are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts is based on application-specific constraints:

The UB5C-10RF8 is suitable for applications requiring operation across the full temperature range of -55°C ~ 250°C and where compact physical dimensions (6.40mm x 12.70mm) are advantageous. The UB5C-10RF8 includes current sensing, flame proof, moisture resistant, and pulse withstanding features.

The WHE10RFET is suitable for applications operating within the -55°C ~ 150°C temperature window where larger physical dimensions (7.50mm x 20.00mm) are acceptable. Both components deliver equivalent electrical performance within their respective operating ranges.

Frequently Asked Questions (FAQ)

Q: Can WHE10RFET replace UB5C-10RF8 in all applications?

A: WHE10RFET is electrically equivalent for resistance, tolerance, power rating, and temperature coefficient. Substitution is valid for applications operating within the overlapping temperature range of -55°C ~ 150°C. Applications requiring operation above 150°C must use the UB5C-10RF8. Physical dimension differences must be verified for PCB layout compatibility.

Q: What are the key differences between these parts?

A: The primary differences are operating temperature range (UB5C-10RF8 extends to 250°C versus WHE10RFET at 150°C) and physical dimensions (UB5C-10RF8 is more compact). The UB5C-10RF8 includes additional features such as flame proof and pulse withstanding characteristics. Both parts are wirewound, axial package, 10 Ohm, 1% tolerance, 5W resistors with identical temperature coefficients.

Q: Are both parts RoHS compliant?

A: Yes, both UB5C-10RF8 and WHE10RFET are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What packaging formats are available?

A: UB5C-10RF8 is supplied in Tape & Reel (TR) format. WHE10RFET is supplied in Cut Tape (CT) format. Packaging format selection depends on assembly process requirements and order quantity.

Q: How do physical dimensions affect substitution?

A: The UB5C-10RF8 measures 0.250" diameter x 0.500" length, while WHE10RFET measures 0.295" diameter x 0.787" length. PCB layout, component spacing, and thermal management considerations must accommodate the larger dimensions of the WHE10RFET before substitution.
