Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012J824CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 820 kOhms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Tolerance Consideration: The RC2012J824CS specifies ±5% tolerance. Direct substitutes maintain this tolerance specification. Upgrade substitutes feature ±1% tolerance, which provides tighter resistance accuracy and is electrically compatible with circuits designed for ±5% components.

Certification Enhancement: Several substitute parts include automotive AEC-Q200 certification, which is not present in the main part. This certification is an enhancement and does not prevent substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance):

RC0805JR-07820KL from YAGEO provides direct electrical equivalence to the RC2012J824CS with matching ±5% tolerance specification. This part is recommended as the primary substitute when tolerance matching is required and inventory availability is the only concern.

Upgrade Substitutes (Enhanced Tolerance):

All remaining active substitute parts feature ±1% tolerance, which represents an improvement over the original ±5% specification. These parts are electrically compatible with circuits designed for the RC2012J824CS and provide superior resistance accuracy. Selection among upgrade substitutes should be based on product status and application requirements:

• RC0805FR-07820KL (YAGEO): Active status, moisture resistant features, 42,951 units in inventory
• AC0805FR-07820KL (YAGEO): Active status, automotive AEC-Q200 certified, 5,190 units in inventory
• ERJ-6ENF8203V (Panasonic): Active status, automotive AEC-Q200 certified, 70,237 units in inventory (highest inventory availability)
• KTR10EZPF8203 (Rohm): Active status, automotive AEC-Q200 and high voltage rated, 14,524 units in inventory
• RMCF0805FT820K (Stackpole): Active status, automotive AEC-Q200 certified, 2,530 units in inventory
• CRCW0805820KFKEA (Vishay Dale): Active status, automotive AEC-Q200 certified, 27,289 units in inventory
• CRG0805F820K (TE Connectivity): Active status, 880 units in inventory

Discontinued Part:

MCR10ERTF8203 from Rohm Semiconductor is marked as discontinued at DiGi Electronics and should not be selected for new designs or long-term production applications.

Non-Equivalent Part:

CRCW0805820KFKEAHP from Vishay Dale features 0.5W (1/2W) power rating, which differs from the 0.125W specification of the RC2012J824CS. This part is not electrically equivalent and is not recommended as a substitute.

Frequently Asked Questions (FAQ)

Q: Can RC0805JR-07820KL replace RC2012J824CS in my circuit?

A: Yes. RC0805JR-07820KL from YAGEO is a direct equivalent with identical resistance (820 kOhms), tolerance (±5%), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). Both parts are ROHS3 compliant with MSL 1 rating.

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

A: The primary difference is tolerance specification. The RC2012J824CS specifies ±5% tolerance, while upgrade substitutes specify ±1% tolerance. The ±1% tolerance provides tighter resistance accuracy and is electrically compatible with circuits designed for ±5% components. All other electrical and mechanical parameters remain equivalent.

Q: Can I use a ±1% tolerance part in place of a ±5% tolerance part?

A: Yes. A ±1% tolerance part is a direct upgrade and will function correctly in any circuit designed for a ±5% tolerance component. The tighter tolerance ensures the actual resistance value falls within a narrower range, which is beneficial for precision applications.

Q: Why do some substitute parts have automotive AEC-Q200 certification?

A: Automotive AEC-Q200 certification indicates the part meets automotive industry reliability and quality standards. This certification is an enhancement and does not prevent use in non-automotive applications. Parts with this certification are suitable for both automotive and general industrial use.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life. The component does not require special moisture-controlled storage conditions and can be stored under standard industrial conditions without degradation.

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

A: Most substitute parts are available in Tape & Reel (TR) packaging, which is standard for high-volume production. MCR10ERTF8203 is available in Cut Tape (CT) & Digi-Reel® packaging. Verify packaging availability with your supplier before ordering.

Q: What is the significance of the height difference between parts?

A: Height differences (ranging from 0.50mm to 0.70mm maximum seated height) are within acceptable tolerances for 0805 package components. These variations do not affect electrical performance or PCB assembly compatibility for standard applications. Verify height specifications only if your design has specific spatial constraints.

Q: Why is CRCW0805820KFKEAHP listed but not recommended?

A: CRCW0805820KFKEAHP features 0.5W (1/2W) power rating instead of the 0.125W (1/8W) specification of the RC2012J824CS. This difference makes it electrically non-equivalent and unsuitable as a direct substitute. Use this part only if your circuit requires higher power dissipation capability.

Q: Which substitute has the highest inventory availability?

A: ERJ-6ENF8203V from Panasonic Electronic Components has the highest inventory with 70,237 units in stock. This part is automotive AEC-Q200 certified and maintains all electrical equivalence parameters.

Q: Can I mix different substitute parts in the same production batch?

A: Yes, all active substitute parts with matching electrical specifications (820 kOhms, 0.125W, ±1% or ±5% tolerance, 0805 package) are electrically interchangeable. However, for consistency and traceability, it is recommended to use a single part number per production batch when possible.
