RC1608F244CS Equivalent & Substitute Parts

Part Overview

The RC1608F244CS is a 240 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format. This surface mount device is rated for 0.1W (1/10W) power dissipation and operates across the temperature range of -55°C to 155°C. The component is classified as Active product status and is RoHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life). Equivalent and substitute parts are identified when alternative manufacturers offer identical or functionally compatible 240 kOhms ±1% 0.1W 0603 chip resistors that meet the same electrical specifications and package requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F244CS are qualified based on the following critical parameters:

Electrical Specifications: Resistance value of 240 kOhms, tolerance of ±1%, and power rating of 0.1W (1/10W) must be identical across all substitute candidates.

Package Compatibility: All substitute parts must use the 0603 (1608 Metric) surface mount package with two terminations to ensure mechanical and electrical compatibility with existing PCB layouts.

Environmental and Compliance Requirements: Operating temperature range of -55°C to 155°C, temperature coefficient of ±100ppm/°C, RoHS3 compliance, and Moisture Sensitivity Level 1 are mandatory matching criteria.

Composition: Thick film construction is the standard composition for this resistor category.

Substitute parts are categorized as Direct, Upgrade, or Similar based on feature alignment. Direct substitutes match all parameters without additional features. Upgrade substitutes include automotive AEC-Q200 qualification or high voltage capability. Similar substitutes may include automotive qualification or alternative packaging formats while maintaining core electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Functionally Equivalent):

CR0603-FX-2403ELF (Bourns Inc.) and RC0603FR-07240KL (YAGEO) are direct functional equivalents to the RC1608F244CS. Both parts maintain identical electrical specifications, package format, and compliance certifications. These substitutes are suitable for applications requiring standard industrial-grade thick film resistors without automotive qualification requirements.

Upgrade Substitutes (Enhanced Capability):

KTR03EZPF2403 (Rohm Semiconductor) qualifies as an upgrade substitute with automotive AEC-Q200 certification and high voltage capability. This part maintains all core electrical parameters while providing additional qualification for automotive applications. The upgrade path is appropriate when designs require enhanced reliability or automotive-grade component qualification.

Similar Substitutes (Automotive Qualified):

AC0603FR-07240KL (YAGEO), CRCW0603240KFKEA (Vishay Dale), ERJ-3EKF2403V (Panasonic Electronic Components), and RMCF0603FT240K (Stackpole Electronics Inc) are similar substitutes with automotive AEC-Q200 certification. These parts meet all electrical and environmental specifications of the main part with the addition of automotive qualification. AC0603FR-07240KL is available in Cut Tape and Digi-Reel packaging format, which differs from the standard Tape & Reel format of other candidates.

All substitute parts are Active product status with RoHS3 compliance and Moisture Sensitivity Level 1, ensuring long-term availability and environmental regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-2403ELF replace RC1608F244CS in any application?

A: CR0603-FX-2403ELF is a direct functional equivalent with identical electrical specifications, package format, and compliance certifications. It is suitable for replacement in applications where the original part is used, provided no application-specific requirements mandate automotive qualification or high voltage capability.

Q: What is the difference between direct and upgrade substitutes?

A: Direct substitutes such as CR0603-FX-2403ELF and RC0603FR-07240KL match all electrical and environmental parameters without additional features. Upgrade substitutes such as KTR03EZPF2403 include automotive AEC-Q200 certification and high voltage capability while maintaining identical core specifications. Upgrade substitutes are appropriate for designs requiring enhanced reliability or automotive-grade qualification.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Most substitute parts are supplied in Tape & Reel (TR) format. AC0603FR-07240KL is available in Cut Tape (CT) and Digi-Reel packaging format. Packaging format selection depends on production volume and assembly equipment compatibility.

Q: Do automotive-qualified substitutes affect circuit performance compared to the original part?

A: Automotive-qualified substitutes such as CRCW0603240KFKEA, ERJ-3EKF2403V, and RMCF0603FT240K maintain identical electrical specifications including resistance value, tolerance, temperature coefficient, and operating temperature range. Automotive qualification represents enhanced manufacturing process control and reliability screening, not a change in electrical performance.

Q: What is Moisture Sensitivity Level 1 and why is it important?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without moisture-related degradation concerns. All listed substitute parts carry MSL 1 rating, ensuring compatibility with standard storage and handling procedures without requiring special moisture-control packaging or baking procedures prior to assembly.

Q: Can KTR03EZPF2403 be used in non-automotive applications?

A: KTR03EZPF2403 is qualified for automotive applications but is not restricted to automotive use. The automotive AEC-Q200 certification and high voltage capability represent additional qualifications that do not preclude use in standard industrial applications. This part is suitable for any application requiring the specified 240 kOhms ±1% 0.1W 0603 resistor.

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 maximum seated height of 0.022" (0.55mm). CRCW0603240KFKEA and RMCF0603FT240K have minor dimensional variations: CRCW0603240KFKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" (0.50mm) maximum height; RMCF0603FT240K measures 0.061" L x 0.031" W (1.55mm x 0.80mm). These variations remain within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: What inventory levels are available for substitute parts?
