Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F3654CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 3.65 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence Requirements:

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria. Variations in height (seated maximum) and specific feature sets (anti-sulfur, automotive AEC-Q200, moisture resistant) do not disqualify substitution when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three components listed—RCS2012F3654CS, CRCW08053M65FKEA, and RC0805FR-073M65L—are Active product status and fully compliant with ROHS3 and REACH requirements. Selection between these parts is based on availability, supply chain considerations, and specific application certifications.

CRCW08053M65FKEA (Vishay Dale) carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications requiring automotive-grade component certification.

RC0805FR-073M65L (YAGEO) and RCS2012F3654CS (Samsung) both feature moisture-resistant characteristics and are suitable for general industrial and consumer applications.

Height variations among the three parts (0.66mm, 0.50mm, and 0.60mm respectively) are within acceptable tolerances for 0805 package specifications and do not impact PCB layout compatibility for standard applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW08053M65FKEA replace RCS2012F3654CS in non-automotive applications?

A: Yes. CRCW08053M65FKEA meets all electrical and mechanical specifications of RCS2012F3654CS. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: Are there any height clearance concerns when substituting these parts?

A: The seated height maximum varies: RCS2012F3654CS (0.66mm), RC0805FR-073M65L (0.60mm), and CRCW08053M65FKEA (0.50mm). All values are within standard 0805 package tolerances. Verify PCB design clearance specifications if height-constrained applications exist.

Q: Do all three parts have identical moisture sensitivity ratings?

A: Yes. All three components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture precautions are required during storage, handling, or assembly.

Q: What is the primary difference between these substitute parts?

A: The primary differences are manufacturer identity and specific feature sets. CRCW08053M65FKEA includes automotive AEC-Q200 certification. RCS2012F3654CS and RC0805FR-073M65L emphasize anti-sulfur or moisture-resistant characteristics. All share identical core electrical specifications and package dimensions.

Q: Are these parts interchangeable on the PCB without design changes?

A: Yes. All three parts conform to 0805 (2012 Metric) package specifications with identical footprint requirements. Direct PCB substitution is possible without layout modification.
