Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608J243CS are categorized based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Core Matching Parameters:

• Resistance value: 24 kOhms (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Compliance: ROHS3 compliant, REACH unaffected (exact match required)

Tolerance Grouping: Substitutes are divided into two tolerance classes:

• Direct Equivalents (±5% tolerance): RC0603JR-0724KL, ERJ-3GEYJ243V, RMCF0603JT24K0
• Upgraded Substitutes (±1% tolerance): ERJ-3EKF2402V, KTR03EZPF2402, RC0603FR-0724KL, RMCF0603FG24K0

Feature Enhancements: Upgraded substitutes include automotive AEC-Q200 certification and/or high voltage capability, providing enhanced reliability for demanding applications while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Same Tolerance ±5%):

RC0603JR-0724KL (YAGEO) and RMCF0603JT24K0 (Stackpole Electronics Inc) provide direct functional equivalence to RC1608J243CS with identical electrical specifications and tolerance. RC0603JR-0724KL maintains moisture-resistant construction matching the original design. RMCF0603JT24K0 adds automotive AEC-Q200 certification for applications requiring enhanced reliability qualification.

ERJ-3GEYJ243V (Panasonic Electronic Components) offers equivalent tolerance with automotive AEC-Q200 certification. Temperature coefficient differs at ±200ppm/°C compared to the original ±100ppm/°C specification.

Upgraded Substitutes (Tighter Tolerance ±1%):

ERJ-3EKF2402V, KTR03EZPF2402, RC0603FR-0724KL, and RMCF0603FG24K0 provide improved tolerance performance at ±1% while maintaining all other electrical and mechanical parameters. These parts are suitable for applications requiring tighter resistance accuracy. All upgraded substitutes maintain ROHS3 compliance and -55°C ~ 155°C operating temperature range.

KTR03EZPF2402 (Rohm Semiconductor) includes high voltage capability in addition to automotive AEC-Q200 certification, providing enhanced performance margin for demanding circuit environments.

All substitute parts are Active product status with unlimited moisture sensitivity level (MSL 1) and REACH unaffected compliance, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can RC0603JR-0724KL directly replace RC1608J243CS without circuit modification?

A: Yes. RC0603JR-0724KL matches all critical electrical parameters: 24 kOhms resistance, ±5% tolerance, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Both components are ROHS3 compliant with MSL 1 rating. No circuit modification is required.

Q: What is the difference between direct equivalents and upgraded substitutes?

A: Direct equivalents (RC0603JR-0724KL, ERJ-3GEYJ243V, RMCF0603JT24K0) maintain ±5% tolerance matching the original RC1608J243CS. Upgraded substitutes (ERJ-3EKF2402V, KTR03EZPF2402, RC0603FR-0724KL, RMCF0603FG24K0) provide tighter ±1% tolerance for applications requiring improved accuracy. All maintain identical power rating, package, and operating temperature range.

Q: Are automotive AEC-Q200 certified parts compatible with non-automotive applications?

A: Yes. Automotive AEC-Q200 certification indicates enhanced reliability qualification and stricter manufacturing controls. These parts are fully compatible with non-automotive applications and provide equivalent or superior performance compared to non-certified alternatives.

Q: What does MSL 1 (Unlimited) moisture sensitivity level mean?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. The component can be stored indefinitely under normal conditions without special moisture control measures, simplifying inventory management and reducing handling complexity.

Q: Can I use RMCF0603FG24K0 in place of RC1608J243CS if my circuit requires ±1% tolerance?

A: Yes. RMCF0603FG24K0 provides ±1% tolerance with identical 24 kOhms resistance, 0.1W power rating, 0603 package, and -55°C ~ 155°C operating range. The component includes automotive AEC-Q200 certification and maintains ROHS3 compliance. Physical dimensions are compatible (0.061" L x 0.031" W versus 0.063" L x 0.031" W original specification).

Q: What is the temperature coefficient difference between ±100ppm/°C and ±200ppm/°C?

A: Temperature coefficient defines resistance change per degree Celsius. ±100ppm/°C produces maximum 2.4 ohms change across the -55°C ~ 155°C range (210°C span). ±200ppm/°C produces maximum 4.8 ohms change. For precision applications, ±100ppm/°C provides tighter temperature stability.

Q: Are all substitute parts available in Cut Tape (CT) packaging?

A: RC0603JR-0724KL and RC0603FR-0724KL are available in Cut Tape (CT) & Digi-Reel® packaging. ERJ-3GEYJ243V, ERJ-3EKF2402V, KTR03EZPF2402, RMCF0603JT24K0, and RMCF0603FG24K0 are supplied in Tape & Reel (TR) packaging. Verify packaging requirements with procurement specifications before component selection.
