RC1608F243CS Equivalent & Substitute Parts

Part Overview

The RC1608F243CS is a 24 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0603 (1608 Metric) package format. This surface mount device 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 is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are necessary when the primary part experiences supply constraints, when alternative packaging formats are required, or when enhanced specifications such as automotive qualification are needed for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1608F243CS is determined by strict equivalence across the following critical parameters: resistance value (24 kOhms), tolerance (±1%), power rating (0.1W), package format (0603 / 1608 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH Unaffected, EAR99). All substitute parts listed maintain these core electrical and mechanical specifications.

Substitute parts are grouped into three categories based on additional features:

Direct Substitutes maintain the moisture resistant feature and standard industrial specifications identical to the main part.

Upgrade Substitutes add automotive AEC-Q200 qualification and high voltage capability while maintaining all core electrical parameters.

Similar Substitutes include automotive AEC-Q200 qualification or enhanced moisture resistance features, with minor dimensional variations within the 0603 package specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes for Standard Applications:

CR0603-FX-2402ELF (Bourns Inc.) and RC0603FR-0724KL (YAGEO) are direct functional equivalents to the RC1608F243CS. Both parts maintain identical electrical specifications, temperature performance, and moisture resistant construction. These substitutes are suitable for applications where the original Samsung part is unavailable. CR0603-FX-2402ELF is available in Cut Tape and Digi-Reel packaging, while RC0603FR-0724KL offers the same packaging options with higher inventory availability (5,300 units).

Upgrade Substitutes for Automotive Applications:

KTR03EZPF2402 (Rohm Semiconductor) provides automotive AEC-Q200 qualification with high voltage capability. This upgrade substitute is appropriate for automotive and industrial applications requiring enhanced reliability standards while maintaining all core electrical parameters. The part is supplied in Tape & Reel packaging.

Similar Substitutes with Enhanced Specifications:

AC0603FR-0724KL (YAGEO), CRCW060324K0FKEA (Vishay Dale), ERJ-3EKF2402V (Panasonic Electronic Components), RMCF0603FG24K0, and RMCF0603FT24K0 (Stackpole Electronics Inc) all include automotive AEC-Q200 qualification. These parts are suitable for applications requiring automotive-grade reliability. RMCF0603FT24K0 offers the highest inventory level (80,186 units) among automotive-qualified options. Minor dimensional variations exist within the 0603 package specification; CRCW060324K0FKEA has slightly reduced dimensions (1.55mm x 0.85mm vs. 1.60mm x 0.80mm standard).

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity level (MSL 1), ensuring regulatory compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-2402ELF replace RC1608F243CS in any application?

A: CR0603-FX-2402ELF is a direct functional equivalent with identical electrical specifications (24 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C operating range) and moisture resistant construction. The primary difference is packaging format: CR0603-FX-2402ELF is supplied in Cut Tape and Digi-Reel, while RC1608F243CS is supplied in Tape & Reel. Both are suitable for identical circuit applications.

Q: What is the difference between standard and automotive-qualified substitutes?

A: Automotive-qualified substitutes (KTR03EZPF2402, AC0603FR-0724KL, CRCW060324K0FKEA, ERJ-3EKF2402V, RMCF0603FG24K0, RMCF0603FT24K0) carry AEC-Q200 certification, indicating compliance with automotive reliability and qualification standards. These parts are required for automotive applications but are also suitable for general industrial use. The RC1608F243CS and direct substitutes (CR0603-FX-2402ELF, RC0603FR-0724KL) do not carry automotive qualification but are suitable for standard industrial and consumer applications.

Q: Are there dimensional differences between substitute parts?

A: Most substitute parts conform to standard 0603 (1608 Metric) dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. CRCW060324K0FKEA and RMCF0603FG24K0 have slightly reduced length dimensions (0.061" / 1.55mm) but maintain the same height and width specifications. These minor variations remain within 0603 package tolerance and do not affect PCB footprint compatibility.

Q: Which substitute offers the best inventory availability?

A: RMCF0603FT24K0 (Stackpole Electronics Inc) offers the highest inventory level at 80,186 units. This automotive-qualified part provides both supply security and AEC-Q200 compliance. RMCF0603FG24K0 (45,925 units) and AC0603FR-0724KL (56,722 units) also provide substantial inventory levels.

Q: Can I use an automotive-qualified substitute in a non-automotive application?

A: Yes. Automotive-qualified substitutes meet or exceed the electrical and environmental specifications of standard industrial parts. Using an automotive-qualified part in a non-automotive application introduces no compatibility issues and may provide enhanced reliability margins.

Q: What packaging options are available for substitutes?

A: The RC1608F243CS is supplied in Tape & Reel (TR) packaging. Direct substitutes CR0603-FX-2402ELF and RC0603FR-0724KL are available in Cut Tape (CT) and Digi-Reel packaging. Automotive-qualified substitutes KTR03EZPF2402, ERJ-3EKF2402V, RMCF0603FG24K0, and RMCF0603FT24K0 are supplied in Tape & Reel. AC0603FR-0724KL and CRCW060324K0FKEA are available in Cut Tape and Digi-Reel. Packaging selection depends on assembly equipment and volume requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, identical to the RC1608F243CS. All parts carry EAR99 ECCN classification and 8533.21.0030 HTSUS code.
