RCS2012F1742CS Equivalent & Substitute Parts

Part Overview

The RCS2012F1742CS is a 17.4 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status and is designed for general-purpose applications requiring anti-sulfur and moisture-resistant characteristics. Substitute parts are identified when original inventory becomes unavailable or when design requirements necessitate alternative sourcing from qualified manufacturers offering equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F1742CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 17.4 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Specifications:

• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental:

• RoHS3 Compliant (required)
• Moisture Sensitivity Level 1 (required)
• REACH Unaffected status (required)

All four substitute parts listed meet these criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer-specific features (Automotive AEC-Q200 certification), and minor dimensional differences in seated height do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F1742CS based on electrical and mechanical parameter matching. Selection among these alternatives is determined by the following factors:

General-Purpose Applications: The RCS2012F1742CS (Samsung), RC0805FR-0717K4L (YAGEO), and RMCF0805FT17K4 (Stackpole) are suitable for applications without automotive qualification requirements. All three maintain anti-sulfur or moisture-resistant characteristics and ROHS3 compliance.

Automotive Applications: The CRCW080517K4FKEA (Vishay Dale), ERJ-6ENF1742V (Panasonic), and RMCF0805FT17K4 (Stackpole) carry Automotive AEC-Q200 certification, qualifying them for automotive-grade applications where this standard is mandated.

Packaging Considerations: Tape & Reel (TR) packaging is available from Samsung, Vishay Dale, YAGEO, and Stackpole. Panasonic offers Cut Tape (CT) and Digi-Reel® formats. Selection depends on assembly equipment compatibility and procurement workflow requirements.

Inventory Availability: Stackpole Electronics (RMCF0805FT17K4) maintains the highest inventory level at 368,768 pieces. Panasonic (ERJ-6ENF1742V) provides 49,648 pieces. YAGEO (RC0805FR-0717K4L) stocks 32,542 pieces. Vishay Dale (CRCW080517K4FKEA) maintains 18,382 pieces.

Frequently Asked Questions (FAQ)

Q: Can CRCW080517K4FKEA replace RCS2012F1742CS in non-automotive applications?

A: Yes. The CRCW080517K4FKEA meets all electrical and mechanical specifications required for substitution. The Automotive AEC-Q200 certification is an additional qualification that does not restrict use in general-purpose applications.

Q: What is the significance of the different seated heights among substitute parts?

A: Seated height variations (0.020" to 0.028") are within acceptable tolerances for 0805 package components and do not affect electrical performance or PCB assembly compatibility. These differences reflect manufacturer-specific design variations in thick film construction.

Q: Are Cut Tape and Tape & Reel formats interchangeable for procurement?

A: Cut Tape (CT) and Tape & Reel (TR) formats serve different assembly workflows. Tape & Reel is standard for automated pick-and-place assembly. Cut Tape is suitable for manual assembly or lower-volume production. Format selection depends on manufacturing process requirements, not component functionality.

Q: Does the absence of AEC-Q200 certification on the Samsung and YAGEO parts limit their application scope?

A: No. AEC-Q200 certification is a qualification standard for automotive applications. Parts without this certification are fully functional for general-purpose, industrial, and consumer applications. Certification presence or absence does not affect electrical or mechanical performance in non-automotive contexts.

Q: Are all substitute parts REACH compliant?

A: Yes. All substitute parts listed carry REACH Unaffected status, indicating compliance with REACH regulations. This status is consistent across all manufacturers.

Q: Can these 0805 resistors be used interchangeably on the same PCB layout?

A: Yes. All parts share identical 0805 (2012 Metric) package dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). PCB footprints and land patterns are standardized for this package type across all manufacturers.
