Substitute Part Grouping Explanation

Substitution eligibility for the WSLS2512R0200FHEA is determined by strict equivalence across the following parameters:

• Resistance value: 20 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package format: 2512 (6432 Metric)
• Composition: Metal Element
• Temperature coefficient: ±75ppm/°C
• Operating temperature range: -65°C ~ 170°C
• Automotive qualification: AEC-Q200
• Feature set: Anti-Sulfur, Current Sense, Moisture Resistant, Pulse Withstanding
• Compliance: ROHS3 Compliant, REACH Unaffected

The identified substitute part WSL2512R0200FEA maintains all electrical and mechanical specifications while differing only in series designation and packaging format (Cut Tape & Digi-Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both WSLS2512R0200FHEA and WSL2512R0200FEA are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on:

1. Packaging requirements: WSL2512R0200FEA is available in Cut Tape and Digi-Reel format, while WSLS2512R0200FHEA uses standard packaging.

2. Inventory availability: WSL2512R0200FEA has significantly higher stock (45,300 pieces) compared to WSLS2512R0200FHEA (740 pieces).

3. Compliance and certification: Both parts maintain identical AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status, ensuring equivalent performance in regulated applications.

4. Series designation: The parts belong to different series (WSLS vs. WSL) but maintain functional equivalence through identical parameter specifications.

Frequently Asked Questions (FAQ)

Q: Can WSL2512R0200FEA be used as a direct replacement for WSLS2512R0200FHEA?

A: Yes. Both parts share identical electrical specifications (20 mOhms ±1%, 1W), mechanical dimensions (2512 package), temperature characteristics (±75ppm/°C, -65°C to 170°C), and automotive certifications (AEC-Q200). The difference in series designation does not affect functional compatibility.

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

A: The primary differences are series designation (WSLS vs. WSL) and packaging format. WSLS2512R0200FHEA uses standard packaging, while WSL2512R0200FEA is supplied in Cut Tape and Digi-Reel format. All electrical and mechanical parameters are equivalent.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification, anti-sulfur coating, moisture resistance, and pulse withstanding capability, making them suitable for automotive current sensing applications.

Q: What is the significance of the 2512 package designation?

A: The 2512 package (6432 Metric) defines the physical dimensions: 0.250" L × 0.125" W (6.35mm × 3.18mm) with maximum seated height of 0.035" (0.89mm). Both substitute parts use this identical package format, ensuring PCB footprint compatibility.

Q: Do both parts meet RoHS and REACH compliance?

A: Yes. Both WSLS2512R0200FHEA and WSL2512R0200FEA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection should be based on packaging requirements and supply chain considerations. WSL2512R0200FEA offers higher availability in tape and reel format, while WSLS2512R0200FHEA may be preferred if standard packaging is specified. Both are functionally equivalent for design purposes.
