Key Parameters

Substitute Part Grouping Explanation

Substitution for the WSL2010R0100FEB18 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2010 (5025 Metric)
• Composition: Metal Element
• Temperature coefficient: ±75ppm/°C
• Operating temperature range: -65°C ~ 170°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The identified substitute part maintains identical electrical performance and mechanical compatibility, differing only in manufacturing date code and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both the WSL2010R0100FEB18 and WSL2010R0100FEA18 are active production parts from Vishay Dale's WSL-HP series with identical electrical and mechanical specifications. Selection between these parts should be based on availability and lead time requirements. The WSL2010R0100FEA18 offers significantly higher inventory availability at 35,650 pieces compared to 848 pieces for the FEB18 variant. Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status, making them suitable for equivalent circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can WSL2010R0100FEA18 be used as a direct replacement for WSL2010R0100FEB18?

A: Yes. Both parts are identical in all electrical and mechanical parameters, including resistance value, tolerance, power rating, package type, temperature coefficient, operating temperature range, and automotive qualification. The difference is limited to manufacturing date code and inventory levels.

Q: What determines if a part can substitute for the WSL2010R0100FEB18?

A: Substitution requires matching all critical parameters: 10 mOhms resistance, ±1% tolerance, 1W power rating, 2010 (5025 Metric) package, metal element composition, ±75ppm/°C temperature coefficient, -65°C ~ 170°C operating range, AEC-Q200 rating, and ROHS3 compliance.

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

A: No. Both parts carry identical certifications: AEC-Q200 automotive qualification, ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited).

Q: What is the physical package compatibility between these parts?

A: Both parts use the 2010 (5025 Metric) package with identical dimensions: 0.200" L x 0.100" W (5.08mm x 2.54mm) and maximum seated height of 0.035" (0.89mm). They are mechanically interchangeable on PCB layouts designed for this package.

Q: Which part should be selected based on availability?

A: The WSL2010R0100FEA18 is recommended when lead time is a consideration, as it maintains substantially higher inventory (35,650 pieces) compared to the FEB18 variant (848 pieces). Both parts are active production items with no planned discontinuation.
