• 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 type: 0603 (1608 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

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

The CRCW06038M66FKEA manufactured by Vishay Dale satisfies all electrical and mechanical equivalence criteria. This substitute maintains identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The 0603 package dimensions are functionally equivalent for PCB layout purposes. Both components are RoHS3 compliant with MSL Level 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both the RC1608F8664CS and CRCW06038M66FKEA are Active products with full RoHS3 compliance and MSL Level 1 rating, confirming their suitability for equivalent application use.

The RC1608F8664CS features moisture-resistant construction as specified by Samsung Electro-Mechanics. The CRCW06038M66FKEA carries AEC-Q200 automotive qualification, indicating enhanced reliability screening and performance validation for automotive applications.

Dimensional variations between the two parts are minimal and within standard PCB layout tolerances for 0603 package components. The CRCW06038M66FKEA seated height of 0.020" (0.50mm) is lower than the RC1608F8664CS at 0.022" (0.55mm), which may provide marginal benefits in space-constrained designs.

Packaging format differs: RC1608F8664CS is supplied in Cut Tape (CT) format, while CRCW06038M66FKEA is supplied in Tape & Reel (TR) format. This distinction affects handling and assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can CRCW06038M66FKEA replace RC1608F8664CS in existing designs?

A: Yes. Both components share identical electrical specifications (8.66 MOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C operating range) and are mechanically compatible in 0603 package footprints. Dimensional differences are within standard PCB layout tolerances.

Q: What is the significance of AEC-Q200 qualification on the CRCW06038M66FKEA?

A: AEC-Q200 is an automotive industry standard qualification that certifies enhanced reliability through rigorous testing and screening. This qualification is relevant for automotive applications but does not affect compatibility in non-automotive designs.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect component performance?

A: No. Packaging format affects supply chain logistics, handling procedures, and assembly line compatibility but does not alter electrical or mechanical performance of the resistor itself.
