Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F2103CS is determined by strict equivalence across the following parameters:

Electrical Equivalence: Resistance value (210 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Equivalence: Package designation (0805/2012 Metric) and number of terminations (2) must match exactly.

Environmental Compliance: Operating temperature range (-55°C to 155°C), RoHS3 compliance, and MSL rating (1) must be maintained.

Packaging Format: All substitute parts are supplied in Tape & Reel (TR) format consistent with the original component.

The three substitute parts listed below satisfy all substitution criteria and are direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full electrical and mechanical equivalence to the RCS2012F2103CS. Selection among these alternatives is based on product availability, supply chain considerations, and application-specific certifications:

RC0805FR-07210KL (YAGEO): Features moisture-resistant construction. Seated height maximum 0.024" (0.60mm). Highest inventory availability (77,030 pcs). Suitable for general industrial and consumer applications.

All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805210KFKEA replace RCS2012F2103CS in any application?

A: Yes. Both components share identical electrical specifications (210 kOhms ±1%, 0.125W, ±100ppm/°C), mechanical package (0805), and environmental ratings (-55°C to 155°C, ROHS3, MSL 1). The CRCW0805210KFKEA includes AEC-Q200 automotive certification, making it suitable for automotive applications where the original part may not be specified.

Q: What is the difference between ERJ-6ENF2103V and RC0805FR-07210KL?

A: Both are electrically equivalent 210 kOhms ±1% 0.125W resistors in 0805 package. ERJ-6ENF2103V carries AEC-Q200 automotive qualification; RC0805FR-07210KL does not. RC0805FR-07210KL has higher inventory availability (77,030 pcs vs. 45,681 pcs). Physical height differs: ERJ-6ENF2103V maximum 0.028" (0.70mm), RC0805FR-07210KL maximum 0.024" (0.60mm).

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

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) format, consistent with the original RCS2012F2103CS packaging specification.

Q: Do substitute parts meet the same moisture and temperature specifications?

A: Yes. All substitute parts operate across -55°C to 155°C, maintain MSL rating 1 (Unlimited), and are ROHS3 compliant. The RCS2012F2103CS specifies anti-sulfur and moisture-resistant features; RC0805FR-07210KL explicitly includes moisture-resistant construction. CRCW0805210KFKEA and ERJ-6ENF2103V do not list these specific features in provided data but meet all environmental operating requirements.

Q: Can physical height differences affect PCB assembly?

A: Physical height variations exist among substitutes: RCS2012F2103CS maximum 0.026" (0.66mm), CRCW0805210KFKEA maximum 0.020" (0.50mm), ERJ-6ENF2103V maximum 0.028" (0.70mm), RC0805FR-07210KL maximum 0.024" (0.60mm). These differences are within typical 0805 package tolerance and do not affect standard PCB assembly processes or component placement.
