WHB15RFET Equivalent & Substitute Parts

Part Overview

The WHB15RFET is a 15 Ohm ±1% 1W axial wirewound through-hole resistor manufactured by Ohmite, currently in active production status. This component is designed for applications requiring precision resistance with wirewound construction and tight tolerance specifications. Substitute parts may be required due to inventory availability, packaging format preferences, or specific environmental operating range requirements across different application scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WHB15RFET is determined by matching the following critical parameters: resistance value (15 Ohms), tolerance (±1%), power rating (1W), composition (wirewound), package type (axial), and temperature coefficient (±20ppm/°C). All identified substitute parts meet these core electrical specifications. Packaging format (Tape & Reel, Bulk, or Cut Tape) and physical dimensions may vary while maintaining functional equivalence. Operating temperature range extensions and additional features such as moisture resistance do not preclude substitution but represent enhanced capabilities.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet core electrical specifications for direct substitution. The WHB15RFET and RS01A15R00FE70 both carry ROHS3 compliance and REACH Unaffected status, providing equivalent regulatory alignment. The 41F15RE offers extended operating temperature capability to 275°C, suitable for applications requiring higher thermal performance. The RS01A15R00FE70 includes moisture-resistant construction and operates across -65°C to 250°C, addressing applications in moisture-prone environments. Selection should be based on packaging format availability, operating temperature requirements, and environmental exposure conditions specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 41F15RE substitute for the WHB15RFET in all applications? A: Yes, the 41F15RE meets all core electrical parameters (15 Ohms ±1%, 1W, wirewound, ±20ppm/°C). The primary difference is packaging format (Bulk vs. Tape & Reel) and extended operating temperature range to 275°C. Physical dimensions differ slightly but both are axial through-hole components suitable for standard PCB mounting.

Q: What is the advantage of the RS01A15R00FE70 over the WHB15RFET? A: The RS01A15R00FE70 provides moisture-resistant construction, extended lower temperature limit (-65°C vs. -55°C), and higher upper temperature capability (250°C vs. 150°C). These features make it suitable for harsh environmental applications while maintaining identical electrical specifications.

Q: Are there physical dimension constraints when substituting these parts? A: All three parts are axial through-hole resistors with different physical dimensions. The WHB15RFET measures 0.130" Dia x 0.276" L, the 41F15RE measures 0.126" Dia x 0.437" L, and the RS01A15R00FE70 measures 0.094" Dia x 0.406" L. PCB layout and clearance requirements should be verified before substitution.

Q: Which substitute part has the best regulatory compliance? A: Both the WHB15RFET and RS01A15R00FE70 carry ROHS3 compliance and REACH Unaffected status. The 41F15RE is RoHS Compliant with Vendor Undefined REACH status, making it suitable for most applications but requiring verification for REACH-sensitive markets.

Q: What packaging formats are available for these substitute parts? A: The WHB15RFET is supplied in Tape & Reel format, the 41F15RE in Bulk, and the RS01A15R00FE70 in Cut Tape. Selection depends on assembly process requirements and inventory management preferences.
