Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F4874CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 4.87 MOhms
• 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 compliance
• MSL Level 1 or equivalent
• REACH unaffected status

The CRCW06034M87FKEA 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 compatible with PCB layouts designed for the RC1608F4874CS. Both components are RoHS3 compliant with MSL Level 1 ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the RC1608F4874CS and CRCW06034M87FKEA are Active status components with full RoHS3 compliance and MSL Level 1 ratings. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.

The CRCW06034M87FKEA carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade component standards. This qualification does not restrict use in non-automotive applications and represents an enhanced quality level.

Physical dimensions show minor variations within the 0603 package tolerance envelope. The Vishay Dale component exhibits slightly reduced length (1.55mm vs 1.60mm) and height (0.50mm vs 0.55mm), which remains compatible with standard 0603 PCB footprints and assembly processes.

Both components are suitable for direct substitution in circuit designs where the RC1608F4874CS is specified, provided that PCB layout accommodates standard 0603 package tolerances.

Frequently Asked Questions (FAQ)

Q: Can CRCW06034M87FKEA replace RC1608F4874CS in existing designs?

A: Yes. Both components share identical electrical specifications (4.87 MOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C operating range) and are packaged in the 0603 (1608 Metric) format. Physical dimensions are compatible with standard 0603 PCB footprints. Both maintain RoHS3 compliance and MSL Level 1 ratings.

Q: What are the key differences between these two parts?

A: The primary difference is manufacturer source and automotive qualification. The CRCW06034M87FKEA includes AEC-Q200 automotive qualification, while the RC1608F4874CS features moisture-resistant construction. Both specifications are complementary rather than conflicting. Minor dimensional variations (length and height) fall within standard 0603 package tolerances and do not affect PCB compatibility.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both components are RoHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. The CRCW06034M87FKEA's AEC-Q200 qualification represents an additional quality assurance level and does not introduce compatibility restrictions.

Q: What packaging formats are available for these parts?

A: Both the RC1608F4874CS and CRCW06034M87FKEA are supplied in Tape & Reel (TR) format suitable for automated assembly processes.

Q: Are there any temperature or power rating limitations when substituting?

A: No. Both components operate identically across the -55°C to 155°C temperature range with 0.1W power dissipation capability. Temperature coefficient specifications are identical at ±100ppm/°C.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes, with the note that CRCW06034M87FKEA carries AEC-Q200 automotive qualification, which may be preferred for applications requiring automotive-grade reliability standards. Both components maintain Active product status and full compliance certifications.
