RC2012F2103CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F2103CS is a 210 kOhms ±1% 0.125W chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package. This thick film resistor features moisture resistance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package class, resistance value, tolerance, power rating, and operating temperature range.

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F2103CS is determined by strict equivalence across the following parameters:

Mandatory Equivalence Criteria:

• Resistance value: 210 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in physical dimensions (height-seated maximum) and manufacturer-specific series designations do not affect functional substitution within the specified electrical and thermal parameters.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—RC0805FR-07210KL (YAGEO), CRCW0805210KFKEA (Vishay Dale), and ERJ-6ENF2103V (Panasonic)—are functionally equivalent to the RC2012F2103CS based on electrical and mechanical specifications.

Direct Substitution (RC0805FR-07210KL): The YAGEO RC0805FR-07210KL maintains identical electrical parameters and moisture-resistant thick film composition. This part is the closest functional equivalent with no additional certifications beyond ROHS3 compliance.

Automotive-Rated Alternatives: Both CRCW0805210KFKEA and ERJ-6ENF2103V carry AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability and are interchangeable with the RC2012F2103CS in non-automotive applications where the additional qualification is not detrimental.

All substitute parts maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1). Selection among these options depends on supply chain availability, lead time requirements, and any application-specific certifications mandated by end-use specifications.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07210KL replace RC2012F2103CS directly?

A: Yes. The RC0805FR-07210KL (YAGEO) meets all electrical and mechanical equivalence criteria: 210 kOhms ±1%, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. Physical height variation (0.024" vs. 0.026") is within acceptable PCB assembly tolerances for 0805 components.

Q: What is the difference between the Samsung RC2012F2103CS and the Vishay CRCW0805210KFKEA?

A: Both parts are electrically and mechanically equivalent across all specified parameters. The primary difference is that CRCW0805210KFKEA carries AEC-Q200 automotive qualification, which the RC2012F2103CS does not list. The Vishay part has a lower maximum seated height (0.020" vs. 0.026"), which may provide marginal benefits in space-constrained designs but does not affect functional compatibility.

Q: Are the Panasonic ERJ-6ENF2103V and Samsung RC2012F2103CS interchangeable?

A: Yes. The ERJ-6ENF2103V meets all electrical specifications and package requirements. Like the Vishay part, it includes AEC-Q200 automotive certification. The maximum seated height is 0.028", which is slightly higher than the Samsung part but remains within standard 0805 component tolerances and does not compromise PCB assembly compatibility.

Q: Does the AEC-Q200 rating on substitute parts affect compatibility?

A: No. AEC-Q200 is an additional qualification that does not conflict with or reduce compatibility in non-automotive applications. Parts with AEC-Q200 certification meet or exceed the electrical and reliability requirements of non-certified equivalents and are fully interchangeable.

Q: What is the significance of the height-seated maximum variation among these parts?

A: Height variations (0.020" to 0.028") are within the tolerance band for 0805 (2012 Metric) chip resistors and do not affect electrical performance or standard PCB assembly processes. These variations are relevant only in applications with extreme height constraints, such as ultra-compact stacked component designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts—RC0805FR-07210KL, CRCW0805210KFKEA, and ERJ-6ENF2103V—carry ROHS3 compliance certification, matching the RC2012F2103CS.

Q: What does MSL 1 (Unlimited) mean for these resistors?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All four parts in this comparison carry MSL 1 rating, meaning they can be stored and handled under standard conditions without special moisture control procedures.
