Parameter Comparison

Engineering Selection Recommendations

RC0603FR-071M27L (YAGEO): This part is a direct electrical and mechanical equivalent to the RC1608F1274CS. All critical parameters including resistance, tolerance, power rating, temperature coefficient, and operating temperature range are identical. The component is ROHS3 compliant with MSL 1 rating. This substitute is suitable for direct replacement in applications where the original Samsung part is specified.

CRCW06031M27FKEA (Vishay Dale): This part meets all electrical specifications and compliance requirements of the RC1608F1274CS. The component includes AEC-Q200 automotive qualification, which provides additional reliability assurance for demanding applications. Physical dimensions show minor variations (1.55mm x 0.85mm versus 1.60mm x 0.80mm) and maximum seated height is 0.020" (0.50mm) compared to 0.022" (0.55mm) for the main part. These dimensional differences remain within standard PCB design tolerances for 0603 package footprints. This substitute is appropriate for applications requiring automotive-grade components or where AEC-Q200 qualification is beneficial.

All three parts are active products with established supply availability and full compliance with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-071M27L be used as a direct replacement for RC1608F1274CS?

A: Yes. The RC0603FR-071M27L matches all electrical parameters (1.27 MOhms, ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C) and mechanical specifications (0603 package, 2 terminations, thick film composition). Both components are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format (Tape & Reel versus Cut Tape) and manufacturer, which does not affect functional performance.

Q: What is the difference between CRCW06031M27FKEA and the other substitutes?

A: The CRCW06031M27FKEA is functionally equivalent in all electrical parameters. The distinguishing feature is AEC-Q200 automotive qualification, which indicates the component meets automotive industry reliability standards. Physical dimensions show minor variations within standard 0603 package tolerances. The seated height is 0.020" (0.50mm) compared to 0.022" (0.55mm) for the main part, which remains compatible with standard PCB designs.

Q: Are there packaging differences between these parts?

A: Yes. The RC1608F1274CS is supplied in Cut Tape (CT) packaging, while RC0603FR-071M27L and CRCW06031M27FKEA are supplied in Tape & Reel (TR) format. Both packaging types are standard for surface mount components and do not affect electrical performance. Selection between packaging formats depends on assembly process requirements and volume needs.

Q: Do all substitutes meet the same compliance standards?

A: All three parts are ROHS3 compliant, have MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. The CRCW06031M27FKEA includes additional AEC-Q200 automotive qualification. All parts are active products with established manufacturing and supply chains.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, from an electrical standpoint. All parts have identical electrical specifications and operate within the same temperature range. Physical dimensions are within standard 0603 package tolerances. PCB footprints designed for 0603 (1608 Metric) packages accommodate all three parts. Assembly equipment settings may require minor adjustments due to slight height variations, but this is within normal manufacturing tolerances.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For general-purpose applications, RC0603FR-071M27L provides equivalent performance with established YAGEO supply. For automotive or high-reliability applications, CRCW06031M27FKEA offers AEC-Q200 qualification. All parts meet the specified electrical and compliance requirements for the RC1608F1274CS.
