RC1608F4222CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F4222CS is a 42.2 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.1W (1/10W) power dissipation in a 0603 (1608 Metric) surface mount package. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is designed for general industrial and commercial applications requiring moisture-resistant thick film construction.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative packaging formats are required (such as Tape & Reel instead of Cut Tape), or when application-specific certifications such as automotive AEC-Q200 qualification are mandated by design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F4222CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 42.2 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package / Case: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Number of Terminations: 2

Substitution Categories:

Direct Substitutes (Functionally Identical): Parts that match all mandatory parameters without additional certifications or packaging differences.

Packaging Variants: Parts with identical electrical and mechanical specifications but supplied in alternative packaging formats (Tape & Reel versus Cut Tape).

Application-Specific Variants: Parts that meet all mandatory parameters and include additional automotive AEC-Q200 qualification, suitable for applications requiring this certification.

All substitute parts listed maintain compatibility with the original RC1608F4222CS across electrical performance, thermal characteristics, environmental compliance, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

For Non-Automotive Applications:

The CR0603-FX-4222ELF (Bourns Inc.) and RC0603FR-0742K2L (YAGEO) are direct functional equivalents to the RC1608F4222CS. Both parts match all electrical specifications, thermal characteristics, and compliance requirements. Selection between these options depends on supply chain availability and procurement preferences. The primary difference is packaging format: CR0603-FX-4222ELF and RC0603FR-0742K2L are supplied in Tape & Reel format, whereas the original RC1608F4222CS is supplied in Cut Tape format.

For Automotive Applications Requiring AEC-Q200 Certification:

The AC0603FR-0742K2L (YAGEO), CRCW060342K2FKEA (Vishay Dale), ERJ-3EKF4222V (Panasonic Electronic Components), and RMCF0603FT42K2 (Stackpole Electronics Inc) are qualified substitutes for applications mandating automotive AEC-Q200 compliance. All four parts maintain electrical equivalence to the RC1608F4222CS while providing automotive-grade reliability certification. Selection among these options is based on supply availability, lead time, and established supplier relationships.

Inventory Considerations:

RC0603FR-0742K2L (YAGEO) offers the highest inventory availability at 178,727 pieces. RMCF0603FT42K2 (Stackpole Electronics Inc) provides the second-highest availability at 208,510 pieces. These high-inventory options support rapid procurement for volume production requirements.

All listed substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC1608F4222CS with any of the listed parts without design modification?

A: Yes. All listed substitute parts match the mandatory electrical parameters (42.2 kOhms ±1%, 0.1W power rating), thermal characteristics (±100ppm/°C, -55°C to 155°C operating range), package form factor (0603 / 1608 Metric), and compliance status (ROHS3, MSL 1). Direct substitution is electrically and mechanically valid. Packaging format differences (Cut Tape versus Tape & Reel) do not affect component performance but may impact assembly line handling and inventory management.

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

A: The AC0603FR-0742K2L, CRCW060342K2FKEA, ERJ-3EKF4222V, and RMCF0603FT42K2 carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. The CR0603-FX-4222ELF and RC0603FR-0742K2L do not carry this certification. For non-automotive applications, both categories are functionally equivalent. For automotive applications, AEC-Q200 qualified parts are required by design specification.

Q: Are there physical dimension differences between substitute parts?

A: The CRCW060342K2FKEA (Vishay Dale) and RMCF0603FT42K2 (Stackpole Electronics Inc) have minor dimensional variations. CRCW060342K2FKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) with maximum seated height of 0.020" (0.50mm). RMCF0603FT42K2 measures 0.061" L x 0.031" W (1.55mm x 0.80mm) with maximum seated height of 0.022" (0.55mm). All other parts, including the original RC1608F4222CS, measure 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.022" (0.55mm). These variations fall within standard 0603 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute part offers the best supply availability?

A: RMCF0603FT42K2 (Stackpole Electronics Inc) provides the highest inventory at 208,510 pieces, followed closely by RC0603FR-0742K2L (YAGEO) at 178,727 pieces. Both parts support high-volume production requirements with minimal lead time risk.

Q: Can I use AEC-Q200 qualified parts in non-automotive applications?

A: Yes. AEC-Q200 qualified parts exceed the reliability and quality requirements of non-automotive applications. Using automotive-grade components in general industrial or commercial designs introduces no compatibility issues and provides enhanced reliability margins.

Q: What packaging format should I select for high-volume assembly?

A: Tape & Reel (TR) packaging is standard for automated pick-and-place assembly operations. All substitute parts except the original RC1608F4222CS are supplied in Tape & Reel format. If your assembly process requires Cut Tape (CT) format, the RC1608F4222CS remains the only listed option in that packaging configuration.
