Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WHB1R0FE are qualified based on the following criteria:

• Resistance value: 1 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package: Axial through-hole
• Temperature coefficient: ±50ppm/°C
• Terminations: 2-pin axial configuration
• Regulatory compliance: ROHS3 Compliant

Substitutes are grouped by packaging format (Cut Tape, Bulk) and manufacturer series. Physical dimensions may vary within the axial package envelope. Operating temperature ranges may differ; verify application requirements when extended temperature performance is critical.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Selection between substitutes depends on:

• Packaging format requirements: WHB1R0FET and RS01A1R000FE70 are supplied in Cut Tape format; WHB1R0FE, 41F1R0E, and ALSR011R000FE12 are supplied in Bulk format.
• Operating temperature range: ALSR011R000FE12 and RS01A1R000FE70 support extended temperature operation (-65°C ~ 250°C) compared to the standard WHB1R0FE range (-55°C ~ 150°C).
• Manufacturer preference: Ohmite series (WHB1R0FE, WHB1R0FET, 41F1R0E) or Vishay Dale series (ALSR011R000FE12, RS01A1R000FE70).
• Moisture resistance: ALSR011R000FE12 and RS01A1R000FE70 include moisture-resistant features.

Frequently Asked Questions (FAQ)

Q: Can WHB1R0FET replace WHB1R0FE directly? A: Yes. Both parts are identical in electrical specifications and axial package configuration. The difference is packaging format: WHB1R0FET is supplied in Cut Tape while WHB1R0FE is supplied in Bulk.

Q: What is the difference between Ohmite and Vishay Dale substitutes? A: Electrical specifications (1 Ohm, ±1%, 1W, ±50ppm/°C) are identical. Vishay Dale parts (ALSR011R000FE12, RS01A1R000FE70) offer extended operating temperature range (-65°C ~ 250°C) and moisture-resistant composition. Ohmite parts operate within -55°C ~ 150°C.

Q: Are physical dimensions interchangeable? A: All parts use axial through-hole package configuration. Physical dimensions vary slightly between series. Verify PCB footprint and board layout clearances before substitution, particularly for 41F1R0E (0.126" Dia x 0.437" L) which differs from WHB1R0FE (0.130" Dia x 0.276" L).

Q: Which substitute is recommended for high-temperature applications? A: ALSR011R000FE12 or RS01A1R000FE70 support operating temperatures to 250°C, compared to 150°C maximum for WHB1R0FE. Select based on packaging format requirement (Bulk or Cut Tape).

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed parts maintain ROHS3 compliance and are suitable for applications requiring regulatory certification.
