Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Resistance Value: 820 kOhms (exact match required)
• Package Format: 0805 (2012 Metric) (exact match required)
• Operating Temperature Range: -55°C to 155°C (minimum requirement)
• Composition: Thick Film (exact match required)

Allowable Variations:

• Tolerance: Substitutes with ±1% tolerance are acceptable as they provide tighter specification than the ±5% main part
• Power Rating: Substitutes rated at 0.125W (1/8W) or higher (0.5W/1/2W) are acceptable
• Features: Additional certifications (AEC-Q200, Anti-Sulfur, Pulse Withstanding) do not prevent substitution
• Height: Seated height variations within 0805 package class are acceptable

Non-Substitutable Variations:

• Different resistance values
• Different package sizes
• Operating temperature ranges that do not encompass -55°C to 155°C
• Composition types other than thick film

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Tolerance ±5%):

RC0805JR-07820KL from YAGEO matches the RCS2012J824CS tolerance specification at ±5%. Both parts share identical resistance value, power rating, package format, and operating temperature range. This part provides direct functional equivalence with moisture-resistant properties. Selection is appropriate for applications where tolerance specification is a primary requirement.

Upgraded Substitutes (Tighter Tolerance ±1%):

AC0805FR-07820KL, RC0805FR-07820KL, ERJ-6ENF8203V, KTR10EZPF8203, and CRCW0805820KFKEA all provide ±1% tolerance specification, which exceeds the ±5% requirement of the main part. These parts maintain identical resistance value, power rating, package format, and operating temperature range. All are ROHS3 compliant with MSL 1 rating. Selection of these parts is appropriate when improved tolerance performance is beneficial to circuit design without introducing incompatibility.

Higher Power Rating Substitutes (0.5W / 1/2W):

CRCW0805820KFKEAHP and ERJ-UP6F8203V provide 0.5W power rating in the same 0805 package format. These parts maintain all other critical parameters including resistance value, tolerance (±1%), operating temperature range, and compliance status. Selection is appropriate for applications requiring increased power dissipation capability within the same physical footprint.

Compliance and Certification:

All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) rating, matching the main part specifications. Automotive AEC-Q200 certification is present in multiple substitutes (AC0805FR-07820KL, CRCW0805820KFKEA, CRCW0805820KFKEAHP, ERJ-6ENF8203V, ERJ-UP6F8203V, KTR10EZPF8203) and does not prevent substitution in non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC0805JR-07820KL for RCS2012J824CS?

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

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

A: Tolerance specification defines the acceptable deviation from the nominal resistance value. The RCS2012J824CS has ±5% tolerance, meaning the actual resistance can vary between 780 kOhms and 860 kOhms. Substitutes with ±1% tolerance (such as AC0805FR-07820KL, RC0805FR-07820KL, ERJ-6ENF8203V, KTR10EZPF8203, CRCW0805820KFKEA) provide tighter specification with actual resistance between 811.8 kOhms and 828.2 kOhms. Tighter tolerance substitutes are functionally compatible and provide improved precision for applications sensitive to resistance variation.

Q: Can I use a 0.5W (1/2W) rated resistor in place of a 0.125W (1/8W) rated resistor?

A: Yes. CRCW0805820KFKEAHP and ERJ-UP6F8203V are rated at 0.5W power dissipation in the same 0805 package. Higher power rating indicates greater capability to dissipate heat without exceeding temperature limits. These parts are functionally compatible substitutes and provide additional margin for power dissipation. The physical package dimensions remain identical (0805 format).

Q: Are automotive-rated parts (AEC-Q200) compatible with non-automotive applications?

A: Yes. Automotive AEC-Q200 certification indicates compliance with automotive industry reliability and quality standards. Parts with this certification (AC0805FR-07820KL, CRCW0805820KFKEA, CRCW0805820KFKEAHP, ERJ-6ENF8203V, ERJ-UP6F8203V, KTR10EZPF8203) are fully compatible with non-automotive applications. The certification does not restrict use in other industries and indicates enhanced quality assurance.

Q: What does MSL 1 (Unlimited) rating mean?

A: MSL (Moisture Sensitivity Level) 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture-controlled storage conditions. All parts listed, including the main part RCS2012J824CS, carry this rating, ensuring compatibility in standard storage and handling environments.

Q: Can I substitute parts with different seated heights?

A: Yes. The RCS2012J824CS has maximum seated height of 0.66mm. Substitute parts with lower seated heights (0.50mm to 0.70mm) are compatible within the 0805 package class. Height variation does not affect electrical performance or circuit board assembly compatibility for standard PCB designs. Verify clearance requirements for specific applications with height-sensitive constraints.

Q: What is the significance of Anti-Sulfur feature?

A: Anti-sulfur feature indicates resistance to sulfur contamination in high-sulfur environments. The RCS2012J824CS includes this feature. Substitutes ERJ-UP6F8203V also includes anti-sulfur protection. Substitutes without this feature (AC0805FR-07820KL, CRCW0805820KFKEA, CRCW0805820KFKEAHP, ERJ-6ENF8203V, KTR10EZPF8203, RC0805FR-07820KL, RC0805JR-07820KL) are functionally compatible but may not provide equivalent protection in high-sulfur environments.

Q: Are all substitute parts in the same package format?

A: Yes. All substitute parts listed are specified in 0805 (2012 Metric) package format, matching the RCS2012J824CS. This ensures physical and electrical compatibility for direct board-level substitution without design modification.
