Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2512FK33L0 is determined by the following critical parameters:

• Resistance value: 33 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 2W (exact match required)
• Package type: 2512 (6432 metric) (exact match required)
• Composition: Thick film (exact match required)
• Temperature coefficient: ±200 ppm/°C (exact match required)
• Operating temperature range: -55°C to +155°C (exact match required)
• RoHS compliance: ROHS3 (minimum requirement)
• Moisture sensitivity: MSL 1 (exact match required)

The RCWE251233L0FNEA from Vishay Dale meets all electrical and mechanical specifications while providing additional automotive qualification (AEC-Q200) and moisture-resistant characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR2512FK33L0 and RCWE251233L0FNEA are active production components with ROHS3 compliance and MSL 1 ratings. The electrical specifications are identical across resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Dimensional variations are minimal and within typical manufacturing tolerances for the 2512 package class.

The RCWE251233L0FNEA includes AEC-Q200 automotive qualification and moisture-resistant characteristics, making it suitable for applications requiring automotive-grade reliability. Selection between these parts should be based on application requirements: the CSR2512FK33L0 for general industrial applications, and the RCWE251233L0FNEA for automotive or moisture-sensitive environments.

Frequently Asked Questions (FAQ)

Q: Can RCWE251233L0FNEA be used as a direct replacement for CSR2512FK33L0?

A: Yes. Both parts share identical electrical specifications (33 mOhms, ±1%, 2W, ±200 ppm/°C, -55°C to +155°C) and the same 2512 package footprint. Dimensional differences are within standard manufacturing tolerances for this package class.

Q: What is the significance of AEC-Q200 qualification on the RCWE251233L0FNEA?

A: AEC-Q200 is an automotive industry standard for discrete semiconductors and passive components. This qualification indicates the part has undergone enhanced reliability testing and is suitable for automotive applications. Non-automotive applications are not restricted from using AEC-Q200 qualified parts.

Q: Are there dimensional compatibility concerns between these parts?

A: The CSR2512FK33L0 measures 0.252" L x 0.126" W (6.40mm x 3.20mm) with 0.026" max height, while the RCWE251233L0FNEA measures 0.248" L x 0.124" W (6.30mm x 3.15mm) with 0.028" max height. These variations are typical for 2512 package components and should not cause PCB layout or assembly issues.

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

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

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry the same ECCN (EAR99) and HTSUS (8533.21.0030) classifications.
