Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F3244CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (3.24 MOhms), tolerance (±1%), and power rating (0.125W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C to 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package type (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W), and termination count (2) ensure PCB footprint compatibility and assembly process alignment.

Compliance & Environmental: RoHS3 compliance and MSL 1 rating are mandatory for regulatory and manufacturing process compatibility. REACH status and ECCN classification must remain consistent.

Composition & Construction: Thick film construction type ensures equivalent electrical behavior and reliability characteristics.

The CRCW08053M24FKEA from Vishay Dale meets all substitution criteria with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS2012F3244CS and CRCW08053M24FKEA are Active product status components with full ROHS3 compliance and REACH Unaffected classification. The primary distinction is the Vishay Dale CRCW08053M24FKEA carries AEC-Q200 automotive qualification, which provides additional reliability assurance for automotive applications but does not preclude use in non-automotive designs.

The seated height difference (0.026" vs 0.020") is within typical PCB assembly tolerances and does not affect electrical performance or standard reflow soldering processes. Both components are suitable for direct substitution in applications requiring 3.24 MOhms ±1% 0.125W 0805 chip resistors with thick film construction.

Frequently Asked Questions (FAQ)

Q: Can CRCW08053M24FKEA replace RCS2012F3244CS in all applications?

A: Yes. Both components share identical electrical specifications (3.24 MOhms ±1% 0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and mechanical package (0805 / 2012 Metric). Compliance certifications (ROHS3, REACH Unaffected, EAR99) are equivalent.

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

A: AEC-Q200 is an automotive qualification standard. The CRCW08053M24FKEA meets this specification, indicating suitability for automotive environments. This does not restrict use in non-automotive applications.

Q: Are there packaging differences between these parts?

A: The RCS2012F3244CS is supplied in Tape & Reel (TR) packaging. The CRCW08053M24FKEA is available in Cut Tape (CT) & Digi-Reel® packaging. Both are standard SMD delivery formats compatible with automated assembly equipment.

Q: Does the 0.006" seated height difference affect PCB assembly?

A: No. The height variation (0.026" vs 0.020") is within standard PCB assembly tolerances and does not impact reflow soldering, component placement, or electrical performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RCS2012F3244CS and CRCW08053M24FKEA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.
