Parameter Comparison

Engineering Selection Recommendations

All three part numbers—WSL3637R0100FTA, WSL3637R0100FEA, and WSL3637R0100FEB—are electrically and mechanically identical and maintain full compatibility for current sensing applications in automotive environments. All parts carry AEC-Q200 qualification and are active in production.

The primary differentiators are regulatory compliance status and inventory availability. WSL3637R0100FEA and WSL3637R0100FEB are ROHS3 compliant and REACH unaffected, whereas WSL3637R0100FTA is RoHS non-compliant and REACH affected. Selection should be based on regulatory requirements applicable to the end application and supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Are WSL3637R0100FEA and WSL3637R0100FEB direct substitutes for WSL3637R0100FTA?

A: Yes. All three part numbers are electrically and mechanically identical. They share the same resistance value (10 mOhms), tolerance (±1%), power rating (3W), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 170°C), package type (3637 Nonstandard), physical dimensions, and feature set. All carry AEC-Q200 automotive qualification.

Q: What is the difference between these three part numbers?

A: The electrical and mechanical specifications are identical. The differences are in regulatory compliance: WSL3637R0100FEA and WSL3637R0100FEB are ROHS3 compliant and REACH unaffected, while WSL3637R0100FTA is RoHS non-compliant and REACH affected.

Q: Can I use WSL3637R0100FEA or WSL3637R0100FEB in place of WSL3637R0100FTA in my design?

A: Yes, from an electrical and mechanical standpoint. However, regulatory compliance requirements for your application must be evaluated. If ROHS3 compliance or REACH compliance is required, WSL3637R0100FEA or WSL3637R0100FEB are appropriate selections.

Q: Are all three parts available in the same packaging format?

A: Yes. All three part numbers are supplied in Tape & Reel (TR) packaging format.

Q: Do these parts have the same AEC-Q200 automotive qualification?

A: Yes. All three part numbers carry AEC-Q200 qualification and are suitable for automotive applications.

Q: What is the moisture sensitivity level for these parts?

A: All three part numbers have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity constraints.
