Substitute Part Grouping Explanation

Substitution eligibility for the WSLS2512R0330FGEA is determined by strict equivalence across the following parameters:

• Resistance value: 33 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package form factor: 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 WSL2512R0330FEA meets all these criteria and qualifies as a direct substitute. The primary distinction is packaging format: the main part uses standard packaging while the substitute is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Both the WSLS2512R0330FGEA and WSL2512R0330FEA are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability.

The WSLS2512R0330FGEA is suitable for applications requiring standard packaging format. The WSL2512R0330FEA in Tape & Reel format is appropriate for high-volume automated assembly processes. Both parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating, making them interchangeable from an engineering and regulatory standpoint.

Frequently Asked Questions (FAQ)

Q: Can WSL2512R0330FEA replace WSLS2512R0330FGEA in my design?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (33 mOhms), tolerance (±1%), power rating (1W), package dimensions (2512/6432 Metric), and automotive qualifications (AEC-Q200). The only difference is packaging format: standard versus Tape & Reel.

Q: What is the significance of the packaging difference?

A: Packaging format affects handling and assembly processes. Standard packaging is suitable for manual or small-batch assembly. Tape & Reel format is optimized for automated pick-and-place equipment in high-volume manufacturing. Electrical and mechanical performance are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the WSLS2512R0330FGEA and WSL2512R0330FEA carry AEC-Q200 qualification, anti-sulfur coating, and moisture resistance, meeting automotive reliability standards.

Q: What does the ±1% tolerance mean for this 33 milliohm resistor?

A: The tolerance specifies the maximum deviation from the nominal 33 milliohm value. At ±1%, the actual resistance will fall between 32.67 mOhms and 33.33 mOhms.

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

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical environmental and regulatory certifications.
