• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 0603 (1608 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these criteria. Packaging format (Tape & Reel) is consistent across all parts. Product status is Active for all alternatives, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RC1608F4224CS (Samsung Electro-Mechanics), RC0603FR-074M22L (YAGEO), and CRCW06034M22FKEA (Vishay Dale)—are functionally equivalent for standard applications requiring a 4.22 MOhms ±1% 0.1W thick film resistor in 0603 package format.

Selection Considerations Based on Provided Data:

The RC0603FR-074M22L (YAGEO) offers the highest inventory availability at 10,844 pieces in stock, supporting high-volume procurement requirements.

The CRCW06034M22FKEA (Vishay Dale) includes Automotive AEC-Q200 qualification, making it suitable for automotive and mission-critical applications where this certification is specified. This part carries 14,313 pieces in inventory.

The RC1608F4224CS (Samsung Electro-Mechanics) maintains 1,055 pieces in stock and provides the original reference specification.

All parts carry identical electrical performance, RoHS3 compliance, and unlimited moisture sensitivity rating (MSL 1). Selection should be based on procurement requirements, inventory availability, application-specific certifications (such as AEC-Q200 for automotive use), and supply chain strategy.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-074M22L (YAGEO) be used as a direct replacement for RC1608F4224CS (Samsung)?

A: Yes. Both parts share identical electrical specifications (4.22 MOhms ±1%, 0.1W, ±100ppm/°C), mechanical package (0603/1608 Metric), composition (thick film), and compliance ratings (RoHS3, MSL 1). They are electrically and mechanically interchangeable.

Q: What is the difference between RC0603FR-074M22L and CRCW06034M22FKEA?

A: The primary difference is that CRCW06034M22FKEA carries Automotive AEC-Q200 qualification, while RC0603FR-074M22L does not. Both parts meet identical electrical and mechanical specifications. The AEC-Q200 rating qualifies CRCW06034M22FKEA for automotive applications where this certification is required.

Q: Are there any physical dimension differences between these parts?

A: Dimensions are nominally equivalent. RC1608F4224CS and RC0603FR-074M22L specify 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. CRCW06034M22FKEA specifies 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" (0.50mm) maximum seated height. These minor variations fall within standard 0603 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Do all three parts have the same moisture sensitivity rating?

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

Q: Which part should be selected for automotive applications?

A: CRCW06034M22FKEA (Vishay Dale) is qualified to Automotive AEC-Q200 standard and should be selected when automotive certification is specified or required by application standards.

Q: Are all parts RoHS3 compliant?

A: Yes. RC1608F4224CS, RC0603FR-074M22L, and CRCW06034M22FKEA all carry ROHS3 Compliant status.
