WHB15RFE Equivalent & Substitute Parts

Part Overview

The WHB15RFE is a 15 Ohm ±1% 1W axial wirewound through-hole resistor manufactured by Ohmite. This component is classified as Active product status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or application-specific packaging needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WHB15RFE are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 15 Ohms, tolerance of ±1%, and power rating of 1W are mandatory matching parameters. Temperature coefficient of ±20ppm/°C is maintained across all qualified substitutes.

Mechanical Compatibility: All substitute parts utilize axial through-hole package configuration with two terminations, ensuring direct board-level compatibility without layout modifications.

Composition: Wirewound construction is maintained across all substitutes to preserve thermal and frequency response characteristics.

Compliance & Certification: Substitutes must maintain RoHS compliance status and REACH compliance alignment with the original part specification.

The following parts meet these substitution criteria:

• 41F15RE (Ohmite Series 40)
• RS01A15R00FE70 (Vishay Dale RS Series)

Parameter Comparison

Engineering Selection Recommendations

WHB15RFE (Primary): Ohmite Series WH part with ROHS3 compliance and REACH unaffected status. Operating temperature range -55°C to 150°C. Compact axial form factor (3.30mm diameter x 7.00mm length). Suitable for standard industrial and commercial applications within specified temperature limits.

41F15RE (Ohmite Alternative): Ohmite Series 40 substitute with extended operating temperature range of -55°C to 275°C. RoHS compliant with vendor-undefined REACH status. Larger axial form factor (3.20mm diameter x 11.10mm length) requires verification of board layout clearance. Recommended for high-temperature applications exceeding 150°C.

RS01A15R00FE70 (Vishay Dale Alternative): Vishay Dale RS Series with moisture-resistant wirewound construction. ROHS3 compliant and REACH unaffected. Extended operating temperature range -65°C to 250°C with lower temperature coefficient floor. Smallest axial form factor (2.39mm diameter x 10.31mm length). Suitable for moisture-prone environments and applications requiring enhanced environmental protection.

Frequently Asked Questions (FAQ)

Q: Can WHB15RFE be directly replaced with 41F15RE on the same PCB?

A: Both parts are axial wirewound resistors with identical electrical specifications (15 Ohms ±1% 1W). Physical dimensions differ: WHB15RFE is 3.30mm diameter x 7.00mm length, while 41F15RE is 3.20mm diameter x 11.10mm length. Board layout clearance must be verified before substitution.

Q: What is the primary difference between WHB15RFE and RS01A15R00FE70?

A: Both parts meet electrical equivalence criteria. RS01A15R00FE70 includes moisture-resistant construction and operates across a wider temperature range (-65°C to 250°C versus -55°C to 150°C). Physical dimensions are smaller (2.39mm diameter x 10.31mm length). Selection depends on environmental exposure and thermal requirements.

Q: Are all three parts RoHS compliant?

A: WHB15RFE and RS01A15R00FE70 are ROHS3 compliant. 41F15RE is RoHS compliant with vendor-undefined REACH status. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Which substitute part has the highest operating temperature rating?

A: 41F15RE supports the highest operating temperature at 275°C maximum, compared to 250°C for RS01A15R00FE70 and 150°C for WHB15RFE. Temperature coefficient remains ±20ppm/°C across all three parts.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (bulk, cut tape) affects supply chain logistics and handling procedures only. Electrical and mechanical performance is determined by the component specifications, not packaging presentation.
