Key Parameters

Substitute Part Grouping Explanation

The WSL2512R0330FEA qualifies as a direct substitute for the WSLS2512R0330FHEA based on the following matching parameters:

• Identical resistance value: 33 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 automotive qualification: AEC-Q200
• Identical feature set: Anti-Sulfur, Current Sense, Moisture Resistant, Pulse Withstanding
• Identical RoHS and MSL compliance

The primary difference is packaging format: WSLS2512R0330FHEA is supplied in standard packaging, while WSL2512R0330FEA is supplied in Tape & Reel (TR) format. Both parts are manufactured by Vishay Dale and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both WSLS2512R0330FHEA 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:

• Select WSLS2512R0330FHEA for applications requiring standard packaging format
• Select WSL2512R0330FEA for high-volume production requiring Tape & Reel format for automated assembly

Both parts maintain full AEC-Q200 automotive compliance, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1). No functional or performance differences exist between these parts.

Frequently Asked Questions (FAQ)

Q: Can WSL2512R0330FEA be used as a direct replacement for WSLS2512R0330FHEA?

A: Yes. Both parts have identical electrical specifications (33 mOhms, ±1%, 1W), identical package dimensions (2512/6432 Metric), and identical feature sets. The only difference is packaging format: standard versus Tape & Reel. Electrical and mechanical compatibility is complete.

Q: What is the difference between standard packaging and Tape & Reel format?

A: Standard packaging is used for manual handling and small-quantity applications. Tape & Reel format is designed for automated pick-and-place assembly equipment in high-volume manufacturing. Both formats contain identical components.

Q: Are both parts suitable for automotive applications?

A: Yes. Both WSLS2512R0330FHEA and WSL2512R0330FEA carry AEC-Q200 qualification, anti-sulfur coating, and are rated for the automotive temperature range of -65°C to 170°C.

Q: Do these parts have the same moisture sensitivity rating?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should be selected for PCB assembly?

A: For automated assembly lines, select WSL2512R0330FEA (Tape & Reel format). For manual assembly or low-volume applications, either format is acceptable based on handling preference.
