Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: resistance value (15 mOhms), tolerance (±1%), package type (2512), composition (metal element), and automotive qualification (AEC-Q200). All substitute parts maintain these core electrical and mechanical specifications.

The substitute parts are grouped into three categories:

Direct Equivalent (Same Electrical & Thermal Specifications): WSL2512R0150FEA and WSLT2512R0150FEA maintain identical resistance, tolerance, power rating, and package dimensions. The primary difference is packaging format (Tape & Reel) and series designation.

Upgraded Performance (Enhanced Power Rating): WSL2512R0150FEA18 provides 2W power rating in the same 2512 package, enabling higher current handling while maintaining all other electrical parameters.

Extended Temperature Range: WSLT2512R0150FEA extends the operating temperature range to -65°C ~ 275°C compared to the standard -65°C ~ 170°C, suitable for high-temperature automotive applications.

Parameter Comparison

Engineering Selection Recommendations

WSL2512R0150FEA is the direct functional equivalent with identical electrical and thermal specifications. This part is recommended for applications requiring Tape & Reel packaging and offers the highest inventory availability (16493 units). All automotive and compliance certifications are maintained.

WSL2512R0150FEA18 is selected when circuit design requires enhanced thermal performance or higher current capacity. The 2W power rating provides additional margin in high-current sense applications while maintaining the same package footprint and electrical characteristics. This part is suitable for designs operating near thermal limits.

WSLT2512R0150FEA is specified for applications requiring extended high-temperature operation up to 275°C. This part maintains anti-sulfur coating and all automotive qualifications while extending the upper operating temperature by 105°C. Selection is based on thermal environment requirements and AEC-Q200 compliance.

All substitute parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and MSL 1 moisture sensitivity rating, ensuring compatibility with automotive supply chain requirements and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can WSL2512R0150FEA replace WSLS2512R0150FHEB directly?

A: Yes. Both parts have identical resistance (15 mOhms), tolerance (±1%), power rating (1W), package (2512), and operating temperature range (-65°C ~ 170°C). The primary difference is packaging format: WSLS2512R0150FHEB is supplied in bulk, while WSL2512R0150FEA is supplied in Tape & Reel format. Electrical and thermal performance are equivalent.

Q: When should WSL2512R0150FEA18 be used instead of the standard 1W part?

A: WSL2512R0150FEA18 is selected when the application requires higher power dissipation capability. The 2W rating provides additional thermal margin for high-current sense circuits. The part maintains identical resistance, tolerance, and package dimensions, making it a direct mechanical and electrical upgrade for designs operating at elevated current levels.

Q: What is the advantage of WSLT2512R0150FEA over other substitutes?

A: WSLT2512R0150FEA extends the maximum operating temperature to 275°C, compared to 170°C for standard parts. This extended range is necessary for automotive applications in high-temperature engine compartments or other thermal environments exceeding 170°C. The part maintains anti-sulfur coating, AEC-Q200 qualification, and all other automotive specifications.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed (WSL2512R0150FEA, WSL2512R0150FEA18, WSLT2512R0150FEA) carry AEC-Q200 automotive qualification, meeting automotive reliability and quality standards.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (bulk versus Tape & Reel) does not affect electrical performance, resistance value, tolerance, or thermal characteristics. Format selection is based on manufacturing process requirements and supply chain logistics.

Q: Are all parts ROHS3 compliant?

A: Yes. All parts in this substitution group are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and manufacturing process requirements.
