Substitute Part Grouping Explanation

Substitute parts for the RCS2012F6344CS are qualified based on strict equivalence of the following electrical and mechanical parameters:

• Resistance Value: 6.34 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.125W / 1/8W (exact match required)
• Package Format: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Termination Count: 2 (exact match required)
• Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

All identified substitute parts meet these criteria and are suitable for direct replacement in applications where the RCS2012F6344CS is specified.

Parameter Comparison

Engineering Selection Recommendations

All three components—RCS2012F6344CS (Samsung Electro-Mechanics), CRCW08056M34FKEA (Vishay Dale), and RC0805FR-076M34L (YAGEO)—are electrically and mechanically equivalent and maintain Active product status with full ROHS3 compliance and MSL 1 (Unlimited) ratings.

CRCW08056M34FKEA carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability standards. This part features a maximum seated height of 0.020" (0.50mm), which is the lowest profile among the three options.

RC0805FR-076M34L provides moisture-resistant thick film construction with a maximum seated height of 0.024" (0.60mm), offering a balance between the other two options.

RCS2012F6344CS features anti-sulfur and moisture-resistant properties with a maximum seated height of 0.026" (0.66mm).

Selection between these parts depends on application-specific requirements such as automotive qualification needs, PCB space constraints, and environmental exposure conditions. All three parts are suitable for direct substitution based on electrical performance and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW08056M34FKEA replace RCS2012F6344CS in any application?

A: Yes. Both components share identical electrical specifications (6.34 MOhms, ±1%, 0.125W, ±100ppm/°C) and operate across the same temperature range (-55°C to 155°C). Both are packaged in 0805 (2012 Metric) format with two terminations. The CRCW08056M34FKEA includes AEC-Q200 automotive qualification, which provides additional reliability assurance for automotive applications.

Q: What is the difference in physical height between these parts?

A: The maximum seated heights are: RCS2012F6344CS at 0.026" (0.66mm), RC0805FR-076M34L at 0.024" (0.60mm), and CRCW08056M34FKEA at 0.020" (0.50mm). These variations are within typical PCB assembly tolerances and do not affect electrical performance. Height differences may be relevant only in space-constrained applications with strict clearance requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. RCS2012F6344CS, CRCW08056M34FKEA, and RC0805FR-076M34L are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, indicating no moisture sensitivity restrictions during storage and handling.

Q: What is the significance of AEC-Q200 qualification on the CRCW08056M34FKEA?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. The CRCW08056M34FKEA meets this standard, making it suitable for automotive applications where such certification is required or preferred.

Q: Can these parts be used interchangeably in production?

A: Yes. All three parts meet identical electrical and mechanical specifications for the 6.34 MOhms ±1% 0.125W 0805 thick film resistor category. They are suitable for direct substitution in manufacturing and assembly processes without circuit redesign or re-qualification.

Q: Are there any packaging differences between these parts?

A: All three parts are supplied in Tape & Reel (TR) packaging format, which is standard for automated PCB assembly. No packaging conversion is required for interchangeable use.
