Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F4534CS are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 4.53 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical specifications. Differences in physical height, specific feature sets (automotive qualification, anti-sulfur properties), and manufacturer series do not affect functional interchangeability within the defined parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

RCS2012F4534CS (Samsung Electro-Mechanics) Primary selection for applications requiring anti-sulfur and moisture-resistant thick film construction. Active product status with ROHS3 compliance and unlimited MSL rating. Suitable for general industrial and consumer applications.

Active product status with ROHS3 compliance. Higher inventory availability (23,903 pcs) supports high-volume production requirements.

RC0805FR-074M53L (YAGEO) Qualified substitute featuring moisture-resistant thick film construction. Intermediate seated height (0.024") between primary and automotive-qualified options. Active product status with ROHS3 compliance. Substantial inventory availability (11,050 pcs) supports standard production schedules.

All three parts are Active status products with ROHS3 compliance and MSL 1 rating, ensuring regulatory compliance and environmental stability across specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054M53FKEA replace RCS2012F4534CS in non-automotive applications? A: Yes. CRCW08054M53FKEA meets all electrical and mechanical parameters required for substitution. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: What is the significance of the height difference between substitute parts? A: Seated heights vary: RCS2012F4534CS (0.66mm), RC0805FR-074M53L (0.60mm), and CRCW08054M53FKEA (0.50mm). These differences are within typical PCB assembly tolerances for 0805 packages. Verify clearance requirements for specific board designs, particularly in high-density layouts.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RCS2012F4534CS, CRCW08054M53FKEA, and RC0805FR-074M53L are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Which substitute part offers the best inventory availability? A: CRCW08054M53FKEA (Vishay Dale) provides the highest inventory level at 23,903 pcs, followed by RC0805FR-074M53L (YAGEO) at 11,050 pcs.

Q: Do all parts share identical electrical performance? A: Yes. All three parts specify 4.53 MOhms ±1% resistance, 0.125W power rating, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range.

Q: Is the anti-sulfur feature of RCS2012F4534CS critical for substitution? A: Anti-sulfur and moisture-resistant properties are specific features of the Samsung part. RC0805FR-074M53L includes moisture-resistant properties. CRCW08054M53FKEA does not specify these features. Verify environmental exposure requirements for your application before selecting a substitute.
