RC1005J240CS Equivalent & Substitute Parts Reference

Part Overview

The RC1005J240CS is a 24 Ohm ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0402 (1005 Metric) package format. This surface mount device is rated for 0.063W (1/16W) power dissipation with moisture resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions.

Equivalent and substitute parts are identified when design requirements permit tolerance relaxation, power rating increases, or when alternative manufacturers provide identical electrical and mechanical specifications within the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for the RC1005J240CS are established based on strict electrical and mechanical parameter matching within the 0402 package format. The primary substitution criteria are:

Direct Equivalents maintain identical resistance value (24 Ohms), tolerance (±5%), power rating (0.063W), package (0402), composition (thick film), and temperature operating range (-55°C to 155°C). These parts are interchangeable without circuit redesign.

Upgrade Substitutes provide improved tolerance (±1% instead of ±5%) or increased power rating (0.1W instead of 0.063W) while maintaining the same 24 Ohm resistance, 0402 package, and operating temperature range. These parts offer enhanced performance margins and are suitable for applications requiring tighter tolerance control or higher power dissipation capability.

Similar Substitutes match all electrical parameters (24 Ohms, ±5%, 0.063W) and package specifications but include additional automotive qualification (AEC-Q200) certification. These parts are functionally equivalent with enhanced reliability documentation for automotive applications.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical physical dimensions (0.039" L x 0.020" W, 0.016" max height).

Parameter Comparison

Engineering Selection Recommendations

RC0402JR-0724RL (YAGEO) serves as the primary direct equivalent. This part maintains identical electrical specifications (24 Ohms ±5%, 0.063W), package format (0402), and environmental ratings (ROHS3, MSL 1) as the RC1005J240CS. Selection is appropriate for applications requiring standard tolerance performance without automotive qualification requirements.

CRG0402F24R (TE Connectivity Passive Product) functions as an upgrade substitute when circuit design permits tolerance improvement to ±1%. The maintained 0.063W power rating and 0402 package ensure mechanical compatibility. ROHS3 compliance and MSL 1 rating preserve environmental qualification. This part is suitable for precision applications requiring tighter resistance tolerance control.

ERJ-2RKF24R0X (Panasonic Electronic Components) provides upgrade capability through increased power rating (0.1W versus 0.063W) combined with improved tolerance (±1%). Automotive AEC-Q200 certification qualifies this part for automotive applications. The 0402 package and operating temperature range remain unchanged. Selection is appropriate for automotive designs or applications requiring enhanced power dissipation margin.

RMCF0402JT24R0 (Stackpole Electronics Inc) maintains direct electrical equivalence (24 Ohms ±5%, 0.063W) while adding automotive AEC-Q200 qualification. The 0402 package and environmental ratings (ROHS3, MSL 1) match the original specification. This part is suitable for automotive applications where standard tolerance performance is acceptable.

All substitute parts maintain Active product status and are available in Tape & Reel packaging format.

Frequently Asked Questions (FAQ)

Q: Can RC0402JR-0724RL replace RC1005J240CS in any application?

A: Yes. RC0402JR-0724RL is a direct equivalent with identical resistance (24 Ohms), tolerance (±5%), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). No circuit redesign is required.

Q: What is the difference between the upgrade substitutes and the original part?

A: CRG0402F24R and ERJ-2RKF24R0X offer improved tolerance (±1% versus ±5%). ERJ-2RKF24R0X additionally provides increased power rating (0.1W versus 0.063W) and automotive AEC-Q200 certification. These upgrades are backward compatible with the original 0402 package footprint.

Q: Are automotive-qualified parts (ERJ-2RKF24R0X, RMCF0402JT24R0) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed standard industrial specifications. AEC-Q200 certification indicates enhanced reliability testing and documentation. These parts function identically to non-automotive equivalents in standard applications.

Q: Does tolerance improvement from ±5% to ±1% affect physical dimensions or package compatibility?

A: No. All parts maintain identical 0402 package dimensions (0.039" L x 0.020" W, 0.016" max height). Tolerance is an electrical specification that does not affect mechanical footprint or PCB layout.

Q: Can I use ERJ-2RKF24R0X (0.1W) in place of RC1005J240CS (0.063W) without circuit modification?

A: Yes. The higher power rating (0.1W) is a performance upgrade that maintains backward compatibility. The part occupies the same 0402 footprint and operates within the identical temperature range. No circuit redesign is necessary.

Q: What is MSL Level 1 and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life under standard storage conditions (23°C, 50% relative humidity). All listed parts carry MSL 1 rating, ensuring consistent moisture handling requirements across substitutions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed maintain ROHS3 compliance, ensuring compatibility with environmental regulations and supply chain requirements identical to the original RC1005J240CS specification.
