Key Parameters

Substitute Part Grouping Explanation

The WSL2512R1000FEA qualifies as a direct substitute for the WSLS2512R1000FGEA based on the following matching parameters:

• Identical resistance value: 100 mOhms
• Identical tolerance: ±1%
• Identical power rating: 1W
• Identical package: 2512 (6432 Metric)
• Identical composition: Metal Element
• Identical temperature coefficient: ±75ppm/°C
• Identical operating temperature range: -65°C ~ 170°C
• Identical feature set: Anti-Sulfur, Automotive AEC-Q200, Current Sense, Moisture Resistant, Pulse Withstanding
• Identical RoHS and REACH compliance status
• Identical MSL rating: 1 (Unlimited)

The primary difference is the series designation (WSLS versus WSL) and packaging format (bulk versus Cut Tape & Digi-Reel). Both parts are manufactured by Vishay Dale and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the WSLS2512R1000FGEA and WSL2512R1000FEA are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and supply requirements:

The WSLS2512R1000FGEA is suitable for applications requiring bulk packaging with current inventory of 966 pieces. The WSL2512R1000FEA is available in Cut Tape and Digi-Reel packaging formats with significantly higher inventory availability (66,300 pieces), making it preferable for high-volume production runs or when tape-and-reel handling is required.

Both parts meet AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. The identical electrical performance, temperature characteristics, and feature set ensure functional interchangeability in current sense applications across the specified operating temperature range of -65°C to 170°C.

Frequently Asked Questions (FAQ)

Q: Can WSL2512R1000FEA be used as a direct replacement for WSLS2512R1000FGEA?

A: Yes. Both parts have identical resistance (100 mOhms), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±75ppm/°C), and operating range (-65°C ~ 170°C). They are functionally equivalent for all electrical and thermal applications.

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

A: The primary differences are the series designation (WSLS versus WSL) and packaging format. The WSLS2512R1000FGEA is supplied in bulk packaging, while the WSL2512R1000FEA is available in Cut Tape and Digi-Reel formats. Electrical and mechanical specifications are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification and are rated for automotive use. They feature anti-sulfur coating, moisture resistance, and pulse withstanding capability required for automotive current sensing circuits.

Q: What packaging options are available?

A: The WSLS2512R1000FGEA is supplied in bulk packaging. The WSL2512R1000FEA is available in Cut Tape (CT) and Digi-Reel packaging, which are standard for automated assembly processes.

Q: Do these parts have any moisture sensitivity concerns?

A: No. Both parts have Moisture Sensitivity Level (MSL) rating of 1, which indicates unlimited shelf life without special moisture control requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
