Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC1005J823CS is structured into three categories based on electrical and mechanical parameter alignment:

Direct Equivalent (Same Tolerance & Power Rating): Parts matching 82 kOhms ±5% at 0.063W (1/16W) in 0402 package with identical operating temperature range and temperature coefficient. These parts are functionally interchangeable without circuit redesign.

Upgrade Substitutes (Improved Tolerance): Parts rated 82 kOhms ±1% at 0.063W or 0.1W in 0402 package. Tolerance improvement from ±5% to ±1% provides enhanced circuit accuracy. Power rating upgrade from 0.063W to 0.1W increases thermal margin without affecting electrical performance in standard applications.

Similar Parts (Automotive Certification): Parts matching 82 kOhms ±5% at 0.063W in 0402 package with AEC-Q200 automotive qualification. These parts maintain identical electrical specifications while adding automotive-grade reliability certification.

All substitute candidates maintain the 0402 (1005 Metric) package footprint, thick film composition, -55°C to 155°C operating temperature range, ±100ppm/°C temperature coefficient, ROHS3 compliance, and MSL Level 1 rating.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required):

RC0402JR-0782KL (YAGEO) serves as the primary direct equivalent, matching all electrical and mechanical specifications of the RC1005J823CS. Both parts maintain ±5% tolerance, 0.063W power rating, and moisture-resistant thick film composition. YAGEO RC0402JR-0782KL offers significantly higher inventory availability (296429 Pcs) compared to the Samsung original, ensuring supply continuity. Both parts maintain Active product status and ROHS3 compliance.

For Tolerance-Upgraded Applications:

RC0402FR-0782KL (YAGEO) and RMCF0402FT82K0 (Stackpole Electronics Inc) upgrade tolerance from ±5% to ±1% while maintaining the 0.063W power rating and 0402 package. RC0402FR-0782KL retains moisture-resistant characteristics matching the original part's feature set. RMCF0402FT82K0 adds AEC-Q200 automotive qualification. Both parts are Active with robust inventory levels (8629 Pcs and 106772 Pcs respectively).

For Power-Rated Upgrade Applications:

ERJ-2RKF8202X (Panasonic Electronic Components) provides both tolerance upgrade to ±1% and power rating increase to 0.1W (1/10W). This part includes AEC-Q200 automotive certification and maintains the 0402 package. Selection is appropriate when circuit design permits higher power dissipation capability and automotive-grade reliability is beneficial.

For Automotive-Qualified Designs:

AC0402JR-0782KL (YAGEO) and RMCF0402JT82K0 (Stackpole Electronics Inc) maintain the original ±5% tolerance and 0.063W rating while adding AEC-Q200 automotive qualification. Both parts are suitable for automotive applications requiring equivalent electrical performance with enhanced reliability certification. AC0402JR-0782KL includes moisture-resistant features; RMCF0402JT82K0 provides automotive-grade construction.

Parts to Avoid:

MCR01MRTF8202 (Rohm Semiconductor) is marked as Discontinued at DiGi Electronics and should not be selected for new designs despite offering ±1% tolerance upgrade.

Frequently Asked Questions (FAQ)

Q: Can RC0402JR-0782KL replace RC1005J823CS in all applications?

A: Yes. RC0402JR-0782KL matches all critical parameters: 82 kOhms resistance, ±5% tolerance, 0.063W power rating, 0402 package, -55°C to 155°C operating range, and moisture-resistant thick film composition. Both parts maintain ROHS3 compliance and MSL Level 1 rating.

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

A: Tolerance defines the maximum deviation from the nominal resistance value. ±5% tolerance allows deviation up to ±4.1 kOhms from 82 kOhms nominal. ±1% tolerance restricts deviation to ±0.82 kOhms. Upgrade to ±1% improves circuit accuracy in precision applications. Standard applications typically accept ±5% tolerance.

Q: Can I use ERJ-2RKF8202X as a substitute if my circuit only requires 0.063W?

A: Yes. ERJ-2RKF8202X is rated for 0.1W (1/10W) power dissipation, which exceeds the 0.063W requirement. Higher power rating provides additional thermal margin without affecting electrical performance. The part maintains 82 kOhms resistance, ±1% tolerance, 0402 package, and operating temperature range compatibility.

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

A: Yes. AEC-Q200 certification indicates enhanced reliability testing and quality standards. Parts such as AC0402JR-0782KL and RMCF0402FT82K0 maintain identical electrical specifications to non-automotive equivalents while meeting additional automotive qualification requirements. They are fully compatible with non-automotive designs.

Q: Does package size differ between substitute parts?

A: No. All substitute parts listed maintain the 0402 (1005 Metric) package format with identical footprint dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm). Maximum seated height is 0.016" (0.40mm) for all parts except AC0402JR-0782KL, which measures 0.015" (0.37mm). This minor height variation does not affect PCB assembly compatibility.

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

A: Moisture Sensitivity Level (MSL) 1 indicates Unlimited shelf life without moisture-related degradation. All listed parts maintain MSL Level 1 rating, eliminating moisture-related storage constraints and bake-out requirements prior to assembly.

Q: Which substitute offers the best inventory availability?

A: YAGEO RC0402JR-0782KL provides the highest inventory level at 296429 Pcs, followed by Panasonic ERJ-2RKF8202X at 133794 Pcs and Stackpole RMCF0402FT82K0 at 106772 Pcs. High inventory availability ensures supply continuity and reduces lead time risk.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original RC1005J823CS specification. REACH status is Unaffected for all parts, and ECCN classification is EAR99 across all alternatives.
