• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Secondary Variation Parameters (allowed to differ):

• Tolerance: ±5% (main part) or ±1% (substitute parts with tighter tolerance are functionally equivalent)
• Manufacturer and series designation
• Specific features (anti-sulfur, automotive AEC-Q200, pulse withstanding capability)
• Packaging format (Tape & Reel vs. Cut Tape)
• Height seated maximum (minor dimensional variation within 0805 package specification)

All identified substitute parts maintain electrical and mechanical compatibility with the RCS2012J622CS while offering alternative sourcing options from different manufacturers.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (±5% Tolerance, 0.125W):

AC0805JR-076K2L and RC0805JR-076K2L are direct functional equivalents to the RCS2012J622CS. Both maintain the ±5% tolerance specification and 0.125W power rating. These parts are suitable for applications where the original Samsung part is specified and tolerance grade is the primary selection criterion. Both are ROHS3 compliant with MSL Level 1 rating.

Higher Precision Alternatives (±1% Tolerance, 0.125W):

AC0805FR-076K2L, CRCW08056K20FKEA, ERJ-6ENF6201V, and RC0805FR-076K2L offer tighter tolerance specifications at ±1%. These parts are functionally compatible with the RCS2012J622CS in applications where improved tolerance performance is beneficial. All are ROHS3 compliant with MSL Level 1 rating. The ±1% tolerance provides enhanced precision without changing electrical or mechanical compatibility.

Higher Power Rating Alternatives (±1% Tolerance, 0.5W):

CRCW08056K20FKEAHP and RCS08056K20FKEA are rated at 0.5W (1/2W) power dissipation while maintaining the 0805 package footprint. These parts are suitable for applications requiring higher power handling capability than the original 0.125W specification. Both feature automotive AEC-Q200 qualification and pulse withstanding capability. Selection of these parts is appropriate only when circuit design requires the increased power rating.

Automotive-Qualified Options:

AC0805FR-076K2L, AC0805JR-076K2L, CRCW08056K20FKEA, CRCW08056K20FKEAHP, ERJ-6ENF6201V, and RCS08056K20FKEA carry automotive AEC-Q200 qualification. These parts are suitable for automotive applications or systems requiring automotive-grade component reliability. The RCS2012J622CS does not carry automotive qualification; substitution with AEC-Q200 parts represents an upgrade in qualification level.

Packaging Format Consideration:

RC0805FR-076K2L is supplied in Cut Tape (CT) & Digi-Reel® format, while all other substitute parts are supplied in Tape & Reel (TR) format. The RCS2012J622CS is supplied in Tape & Reel format. Packaging format selection depends on assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can AC0805JR-076K2L be used as a direct replacement for RCS2012J622CS?

A: Yes. AC0805JR-076K2L is a direct functional equivalent. Both parts share identical resistance (6.2 kOhms), tolerance (±5%), power rating (0.125W), package (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Both are ROHS3 compliant with MSL Level 1. The primary difference is manufacturer (YAGEO vs. Samsung Electro-Mechanics) and automotive AEC-Q200 qualification present in the YAGEO part.

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

A: Tolerance specifies the allowable deviation from the nominal resistance value. The RCS2012J622CS has ±5% tolerance, meaning the actual resistance can vary between 5.89 kOhms and 6.51 kOhms. Substitute parts with ±1% tolerance (such as AC0805FR-076K2L) have actual resistance between 6.134 kOhms and 6.266 kOhms. The ±1% tolerance provides tighter control and is suitable for applications requiring higher precision. Parts with ±1% tolerance are functionally compatible with circuits designed for ±5% parts.

Q: Can CRCW08056K20FKEAHP (0.5W) replace RCS2012J622CS (0.125W)?

A: CRCW08056K20FKEAHP is mechanically and electrically compatible with RCS2012J622CS in terms of resistance, package, and operating temperature. However, the 0.5W power rating is four times higher than the original 0.125W specification. This part should be selected only when circuit design requires higher power dissipation capability. Using a higher-rated part in a circuit designed for 0.125W does not create a functional problem but represents over-specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance status, matching the RCS2012J622CS. All parts also carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry qualification standard for passive components. Parts carrying this qualification have undergone additional testing and reliability validation for automotive applications. The RCS2012J622CS does not carry AEC-Q200 qualification. Substitute parts with AEC-Q200 (such as AC0805FR-076K2L, CRCW08056K20FKEA, ERJ-6ENF6201V) represent an upgrade in qualification level and are suitable for automotive or high-reliability applications.

Q: Does package height variation affect PCB assembly compatibility?

A: All substitute parts maintain the 0805 (2012 Metric) package specification with height seated maximum values ranging from 0.020" to 0.028" (0.50mm to 0.70mm). These minor height variations are within standard 0805 package tolerance and do not affect PCB assembly compatibility, reflow soldering, or component placement. Height variation is not a substitution constraint for standard applications.

Q: Can RC0805FR-076K2L (Cut Tape packaging) be used instead of RCS2012J622CS (Tape & Reel)?

A: RC0805FR-076K2L is electrically and mechanically equivalent to RCS2012J622CS. The difference is packaging format: Cut Tape (CT) & Digi-Reel® versus Tape & Reel (TR). Substitution is appropriate when assembly processes support Cut Tape format or when inventory management practices favor this packaging. Electrical and mechanical compatibility are unaffected by packaging format.

Q: Which substitute part offers the best overall compatibility?

A: AC0805JR-076K2L and RC0805JR-076K2L offer the closest functional equivalence, maintaining ±5% tolerance and 0.125W power rating identical to the RCS2012J622CS. Both are ROHS3 compliant with MSL Level 1. AC0805JR-076K2L adds automotive AEC-Q200 qualification as an enhancement. Selection between these parts depends on manufacturer preference and automotive qualification requirements.
