Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F5234CS is determined by strict equivalence across the following parameters:

Electrical Parameters: Resistance value (5.23 MOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package designation (0805 / 2012 Metric), number of terminations (2), and physical dimensions (0.079" L x 0.049" W) must match.

Material & Composition: Thick film construction is required.

Compliance & Environmental: RoHS3 compliance and MSL 1 rating must be maintained.

The CRCW08055M23FKEA from Vishay Dale meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The CRCW08055M23FKEA qualifies as a direct electrical and mechanical equivalent to the RC2012F5234CS. Both components maintain identical electrical specifications, package dimensions, and compliance certifications. The Vishay Dale component carries AEC-Q200 automotive qualification, which represents an additional certification tier beyond the base requirements. Selection between these parts should be based on availability, supply chain requirements, and application-specific qualification status. Both components are Active products with ROHS3 compliance and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the CRCW08055M23FKEA replace the RC2012F5234CS in all applications?

A: Yes. Both components share identical electrical parameters (5.23 MOhms ±1%, 0.125W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), mechanical dimensions (0805 package), and compliance status (ROHS3, MSL 1). Direct substitution is supported.

Q: What is the significance of the AEC-Q200 rating on the Vishay part?

A: AEC-Q200 is an automotive qualification standard. The CRCW08055M23FKEA carries this certification, indicating suitability for automotive applications. The RC2012F5234CS does not list this certification. Selection depends on application requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components measure 0.079" L x 0.049" W (2.00mm x 1.25mm) in the 0805 (2012 Metric) package. The seated height differs slightly (RC2012F5234CS: 0.026" maximum; CRCW08055M23FKEA: 0.020" maximum), but both are within standard 0805 package tolerances and do not affect PCB layout compatibility.

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

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

Q: What compliance certifications apply to both parts?

A: Both the RC2012F5234CS and CRCW08055M23FKEA are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030.
