WHAR10FE Equivalent & Substitute Parts

Part Overview

The WHAR10FE is a 100 mOhms ±1% 0.5W through-hole resistor manufactured by Ohmite in the WH series. This axial wirewound resistor is designed for applications requiring precision low-resistance values with tight tolerance specifications. The part is currently in active production status with 849 units available in original inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across packaging configurations, enabling procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the WHAR10FE is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 mOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Wirewound
• Temperature coefficient: ±90 ppm/°C
• Operating temperature range: -55°C to 150°C
• Package configuration: Axial
• Physical dimensions: 0.100" Dia × 0.200" L
• Number of terminations: 2
• Regulatory compliance: ROHS3 Compliant

The WHAR10FET is classified as a direct substitute based on identical electrical specifications and mechanical form factor. The primary distinction is packaging configuration: WHAR10FET is supplied in Cut Tape (CT) format, whereas WHAR10FE uses standard packaging. Both parts maintain full electrical and thermal equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both WHAR10FE and WHAR10FET are active production components from Ohmite's WH series with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement requirements and assembly processes:

WHAR10FE is appropriate for standard component procurement workflows and applications where conventional packaging is preferred.

WHAR10FET in Cut Tape format is suitable for automated assembly operations and high-volume production environments where tape-and-reel or cut tape feeding systems are utilized. The significantly higher inventory level (3701 units versus 849 units) provides enhanced supply chain availability.

Both parts deliver identical electrical performance and thermal characteristics across the specified operating range of -55°C to 150°C.

Frequently Asked Questions (FAQ)

Q: Can WHAR10FET be used as a direct replacement for WHAR10FE in circuit designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance values (100 mOhms ±1%), power ratings (0.5W), temperature coefficients (±90 ppm/°C), and operating ranges (-55°C to 150°C). The only difference is packaging format.

Q: What is the primary difference between WHAR10FE and WHAR10FET?

A: The packaging configuration differs. WHAR10FE uses standard packaging, while WHAR10FET is supplied in Cut Tape (CT) format. Both maintain identical axial form factor dimensions (0.100" Dia × 0.200" L).

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 classification.

Q: Which part should be selected for automated assembly?

A: WHAR10FET in Cut Tape format is optimized for automated pick-and-place and tape-feeding systems commonly used in high-volume manufacturing.

Q: Is inventory availability a factor in part selection?

A: WHAR10FET has significantly higher inventory (3701 units) compared to WHAR10FE (849 units), which may influence procurement decisions for large-volume orders or extended lead time mitigation.
