RC1608F1131CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F1131CS is a 1.13 kOhms ±1% 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 moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity rating).

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit component sourcing flexibility across qualified manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F1131CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 1.13 kOhms
• 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):

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

All identified substitute parts meet these criteria. Additional qualifications such as Automotive AEC-Q200 certification represent enhanced specifications that do not preclude substitution in non-automotive applications but indicate suitability for more demanding environments.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are electrically and mechanically equivalent to the RC1608F1131CS and maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 classification).

Direct Equivalents (Identical Specifications):

• CR0603-FX-1131ELF (Bourns Inc.)
• RC0603FR-071K13L (YAGEO)

These parts carry identical electrical parameters and moisture-resistant thick film construction without additional automotive qualifications.

Enhanced Specification Alternatives (AEC-Q200 Qualified):

• AC0603FR-071K13L (YAGEO)
• CRCW06031K13FKEA (Vishay Dale)
• ERJ-3EKF1131V (Panasonic Electronic Components)
• RMCF0603FT1K13 (Stackpole Electronics Inc)

These parts meet all base electrical and mechanical requirements and additionally satisfy Automotive AEC-Q200 qualification standards. They are suitable for applications requiring automotive-grade reliability without imposing restrictions on non-automotive use cases.

Packaging Consideration: The RC1608F1131CS is supplied in Cut Tape (CT) format. Substitute parts are predominantly available in Tape & Reel (TR) format, which is standard for high-volume production environments. CRCW06031K13FKEA offers both Cut Tape and Digi-Reel® packaging options.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC0603FR-071K13L for RC1608F1131CS in my design?

A: Yes. RC0603FR-071K13L (YAGEO) is a direct electrical and mechanical equivalent. Both components share identical resistance (1.13 kOhms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and compliance status (ROHS3, MSL 1). The primary difference is packaging format: RC1608F1131CS is supplied in Cut Tape, while RC0603FR-071K13L is supplied in Tape & Reel.

Q: What is the difference between standard and AEC-Q200 qualified parts?

A: AEC-Q200 qualification indicates the component meets Automotive Electronics Council reliability and quality standards for automotive applications. Parts such as AC0603FR-071K13L, CRCW06031K13FKEA, ERJ-3EKF1131V, and RMCF0603FT1K13 carry this certification. All electrical and mechanical parameters remain identical to non-automotive versions. AEC-Q200 qualified parts are suitable for both automotive and non-automotive applications.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape (CT) and Tape & Reel (TR) packaging formats are mechanical delivery methods only. They do not affect component electrical characteristics, performance, or reliability. Selection between formats depends on assembly process requirements and volume considerations.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the RC1608F1131CS specification.

Q: Can I use CRCW06031K13FKEA as a direct replacement if my assembly line uses Tape & Reel format?

A: CRCW06031K13FKEA is electrically and mechanically equivalent and is available in both Cut Tape and Digi-Reel® formats. However, verify that your assembly equipment is compatible with Digi-Reel® format if that is your selected packaging option. Tape & Reel alternatives include CR0603-FX-1131ELF, RC0603FR-071K13L, ERJ-3EKF1131V, and RMCF0603FT1K13.

Q: What is the temperature coefficient specification and why does it matter?

A: All listed parts, including RC1608F1131CS, have a temperature coefficient of ±100ppm/°C. This specification defines the maximum change in resistance value per degree Celsius across the operating temperature range. Identical temperature coefficients ensure predictable circuit behavior across thermal variations.

Q: Are there any dimensional differences between substitute parts?

A: Dimensional variations exist within tolerance. RC1608F1131CS specifies 0.063" L × 0.031" W (1.60mm × 0.80mm) with 0.022" (0.55mm) maximum seated height. CRCW06031K13FKEA specifies 0.061" L × 0.033" W (1.55mm × 0.85mm) with 0.020" (0.50mm) maximum seated height. RMCF0603FT1K13 specifies 0.061" L × 0.031" W (1.55mm × 0.80mm) with 0.022" (0.55mm) maximum seated height. These variations remain within 0603 package class tolerances and do not affect PCB footprint compatibility.
