Substitute Part Grouping Explanation

Substitute parts are organized into three categories based on electrical and mechanical compatibility with the RC1005J243CS:

Direct Equivalent (Same Tolerance ±5%)

• RC0402JR-0724KL (YAGEO): Identical tolerance, power rating, and package specifications. Maintains full electrical and mechanical interchangeability.
• RMCF0402JT24K0 (Stackpole Electronics Inc): Matches tolerance and power rating with automotive AEC-Q200 qualification. Provides equivalent performance with enhanced reliability certification.

Upgraded Performance (Tighter Tolerance ±1%)

• CRG0402F24K (TE Connectivity Passive Product): Reduces tolerance to ±1% while maintaining identical package, power rating, and temperature coefficient. Suitable for applications requiring improved accuracy.
• RC0402FR-0724KL (YAGEO): Provides ±1% tolerance with moisture-resistant thick film composition. Maintains 0.063W power rating and identical package specifications.
• RMCF0402FT24K0 (Stackpole Electronics Inc): Delivers ±1% tolerance with automotive AEC-Q200 qualification. Identical power rating and package compatibility.

Upgraded Power Rating (Higher Dissipation Capacity)

• ERJ-2RKF2402X (Panasonic Electronic Components): Increases power rating to 0.1W (1/10W) with ±1% tolerance and automotive AEC-Q200 qualification. Provides enhanced thermal performance within the same 0402 package footprint.

All substitute parts maintain identical package dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), height specifications (0.016" / 0.40mm maximum), and two-termination configuration. Temperature coefficient remains ±100ppm/°C across all alternatives, and operating temperature range is consistent at -55°C to 155°C.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required)

RC0402JR-0724KL (YAGEO) provides identical electrical and mechanical specifications to the RC1005J243CS. This part maintains ±5% tolerance, 0.063W power rating, and moisture-resistant thick film composition. Selection is appropriate when supply of the original Samsung part is unavailable and design specifications do not require tolerance improvement.

RMCF0402JT24K0 (Stackpole Electronics Inc) offers equivalent performance with automotive AEC-Q200 qualification. This part is suitable for applications requiring enhanced reliability documentation and automotive-grade component traceability while maintaining the original ±5% tolerance specification.

For Improved Accuracy Applications

RC0402FR-0724KL (YAGEO), CRG0402F24K (TE Connectivity Passive Product), and RMCF0402FT24K0 (Stackpole Electronics Inc) all provide ±1% tolerance while maintaining the 0.063W power rating and 0402 package format. These parts are applicable when circuit design requires tighter resistance tolerance than the original ±5% specification. RC0402FR-0724KL and RMCF0402FT24K0 retain moisture-resistant and automotive qualification features respectively.

For Enhanced Thermal Performance

ERJ-2RKF2402X (Panasonic Electronic Components) increases power dissipation capacity to 0.1W (1/10W) within the same 0402 package footprint. This part is selected when thermal analysis indicates the original 0.063W rating is marginal for the application. The part includes automotive AEC-Q200 qualification and ±1% tolerance.

All recommended substitutes maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and -55°C to 155°C operating temperature range. Selection should be based on application requirements for tolerance grade, automotive qualification status, and thermal performance envelope.

Frequently Asked Questions (FAQ)

Q: Can RC0402JR-0724KL be used as a direct replacement for RC1005J243CS without PCB redesign?

A: Yes. RC0402JR-0724KL maintains identical package dimensions (0402 / 1.00mm x 0.50mm), electrical specifications (24 kOhms ±5%, 0.063W), and environmental ratings. No PCB layout modifications are required for this substitution.

Q: What is the difference between the ±5% tolerance parts and ±1% tolerance parts?

A: Tolerance defines the acceptable resistance variation from the nominal 24 kOhm value. ±5% tolerance allows variation between 22.8 kOhms and 25.2 kOhms. ±1% tolerance restricts variation to 23.76 kOhms and 24.24 kOhms. Applications requiring precise voltage dividers, filter networks, or reference circuits benefit from ±1% tolerance parts.

Q: Are automotive AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. Automotive AEC-Q200 qualification indicates enhanced reliability testing and quality assurance. These parts (RMCF0402JT24K0, RMCF0402FT24K0, ERJ-2RKF2402X) are fully compatible with non-automotive applications and provide additional reliability documentation.

Q: What is the significance of the 0.1W power rating in ERJ-2RKF2402X compared to the 0.063W rating in RC1005J243CS?

A: Power rating indicates maximum continuous power dissipation. The 0.1W rating in ERJ-2RKF2402X provides approximately 58% higher thermal capacity within the same 0402 package. This part is selected when circuit analysis indicates the original 0.063W specification is insufficient for the application's power dissipation requirements.

Q: Do all substitute parts maintain the same temperature coefficient?

A: Yes. All listed substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, ensuring consistent thermal stability across the application's operating envelope.

Q: What packaging formats are available for these parts?

A: RC1005J243CS is supplied in Tape & Reel (TR) format. RC0402JR-0724KL and RMCF0402JT24K0 are available in Tape & Reel (TR). RC0402FR-0724KL and ERJ-2RKF2402X are supplied in Cut Tape (CT) & Digi-Reel® format. CRG0402F24K and RMCF0402FT24K0 are available in Tape & Reel (TR). Packaging selection depends on assembly process requirements and volume specifications.

Q: Are moisture-resistant thick film compositions available across all substitute options?

A: Moisture-resistant composition is specified for RC0402JR-0724KL and RC0402FR-0724KL (YAGEO parts). Other substitutes do not specify moisture-resistant features but maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations for standard storage and handling conditions.
