Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: resistance value (20 mOhms), tolerance (±1%), package type (2512), composition (metal element), and automotive qualification (AEC-Q200). Packaging format (Tape & Reel versus Cut Tape) and power rating variations are secondary considerations that do not affect electrical compatibility but may influence procurement and assembly processes.

The substitute parts are grouped as follows:

Direct Equivalent (Packaging Variant): WSL2512R0200FEA differs from the main part only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and series designation (WSL versus WSLS). All electrical and mechanical specifications remain identical.

Upgrade Option (Enhanced Power Rating): WSL2512R0200FEA18 provides the same resistance, tolerance, and package but with 2W power rating (versus 1W) and belongs to the WSL-HP series. This part is suitable for applications requiring higher thermal dissipation capability.

Manufacturer Recommended Alternative (Extended Temperature Range): WSLT2512R0200FEA maintains identical electrical specifications and packaging but extends the operating temperature range to -65°C ~ 275°C and belongs to the WSLT series with anti-sulfur coating.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory and environmental compatibility with the original specification.

WSL2512R0200FEA is electrically and mechanically identical to the main part and is suitable for direct substitution when Cut Tape or Digi-Reel® packaging is acceptable for assembly processes. This part offers the highest inventory availability (45,300 pcs).

WSL2512R0200FEA18 is appropriate for applications where thermal dissipation requirements exceed 1W capacity. The 2W power rating provides additional margin in high-current sense applications while maintaining the same footprint and electrical characteristics. This upgrade option is recommended for designs operating near or at the thermal limits of the 1W specification.

WSLT2512R0200FEA is the manufacturer-recommended alternative for applications requiring extended operating temperature range up to 275°C. This part is suitable for high-temperature automotive environments and maintains anti-sulfur coating and all other performance characteristics of the main part.

Frequently Asked Questions (FAQ)

Q: Can WSL2512R0200FEA be used as a direct replacement for WSLS2512R0200FHEB?

A: Yes. Both parts have identical electrical specifications (20 mOhms ±1%, 1W, ±75ppm/°C), mechanical dimensions (2512 package), and automotive qualification (AEC-Q200). The difference is packaging format: WSL2512R0200FEA is supplied in Cut Tape & Digi-Reel® format, while WSLS2512R0200FHEB is supplied in Tape & Reel format. Compatibility depends on assembly equipment capability to handle the packaging format.

Q: When should WSL2512R0200FEA18 be selected instead of the main part?

A: WSL2512R0200FEA18 should be selected when the application requires power dissipation capability exceeding 1W. The 2W rating provides thermal headroom for high-current sense circuits. All other electrical and mechanical parameters remain identical, ensuring drop-in compatibility at the circuit level.

Q: What is the advantage of WSLT2512R0200FEA over the main part?

A: WSLT2512R0200FEA extends the maximum operating temperature to 275°C compared to 170°C for the main part. This part is specified for automotive applications requiring sustained operation in high-temperature environments. Electrical performance and package dimensions are otherwise identical.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, ensuring compliance with automotive reliability and quality standards.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. All parts, including the main part and all substitutes, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: Can these parts be used interchangeably in production?

A: Electrical and mechanical interchangeability is confirmed for all listed parts. Production interchangeability depends on assembly process compatibility with the specific packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Verify equipment capability before implementing packaging format changes.
