RC1608F5114CS Equivalent & Substitute Parts

Part Overview

The RC1608F5114CS is a 5.11 MOhm thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation with ±1% tolerance and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant and carries Moisture Sensitivity Level 1 (unlimited shelf life). Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when supply chain optimization is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1608F5114CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 5.11 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Parameters:

• Package format: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances and differences in specific features (such as automotive qualification) do not preclude substitution when all electrical and core mechanical parameters are equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RC1608F5114CS (Samsung Electro-Mechanics), RC0603FR-075M11L (YAGEO), and CRCW06035M11FKEA (Vishay Dale)—are functionally equivalent for applications requiring a 5.11 MOhm, ±1%, 0.1W thick film chip resistor in 0603 package format.

RC1608F5114CS (Samsung Electro-Mechanics): Primary part with active product status and ROHS3 compliance. Suitable for general industrial and consumer applications.

RC0603FR-075M11L (YAGEO): Direct equivalent with active product status and ROHS3 compliance. Offers high inventory availability (17,650 pcs in stock). Suitable for general industrial and consumer applications.

CRCW06035M11FKEA (Vishay Dale): Equivalent part with active product status, ROHS3 compliance, and AEC-Q200 automotive qualification. Highest inventory availability (32,698 pcs in stock). Suitable for automotive and high-reliability applications where AEC-Q200 certification is required or preferred.

Selection between these parts should be based on availability, lead time, cost considerations, and application-specific requirements such as automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-075M11L be used as a direct replacement for RC1608F5114CS?

A: Yes. Both parts share identical electrical specifications (5.11 MOhms, ±1%, 0.1W), temperature characteristics (±100ppm/°C, -55°C to 155°C), package format (0603/1608 Metric), composition (thick film), and compliance status (ROHS3, MSL 1). They are electrically and mechanically interchangeable.

Q: Can CRCW06035M11FKEA be used as a direct replacement for RC1608F5114CS?

A: Yes. All electrical parameters, temperature specifications, package format, composition, and compliance requirements are identical. The CRCW06035M11FKEA includes additional AEC-Q200 automotive qualification, which does not prevent its use in non-automotive applications.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within standard manufacturing tolerances. RC1608F5114CS and RC0603FR-075M11L specify 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. CRCW06035M11FKEA specifies 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" (0.50mm) maximum seated height. These variations are within standard PCB design tolerances and do not affect interchangeability.

Q: What is the significance of AEC-Q200 qualification on the CRCW06035M11FKEA?

A: AEC-Q200 is an automotive industry qualification standard. The CRCW06035M11FKEA meets this standard, making it suitable for automotive applications. However, this qualification does not restrict its use in non-automotive applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC1608F5114CS, RC0603FR-075M11L, and CRCW06035M11FKEA are all ROHS3 compliant and carry Moisture Sensitivity Level 1 (unlimited shelf life).

Q: Which part has the best availability?

A: CRCW06035M11FKEA (Vishay Dale) has the highest inventory availability at 32,698 pcs in stock, followed by RC0603FR-075M11L (YAGEO) at 17,650 pcs in stock.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All three parts are pin-compatible, package-compatible, and electrically equivalent. No design modifications are required for substitution.
