RC2012F3833CS Equivalent & Substitute Parts

Part Overview

The RC2012F3833CS is a 383 kOhms ±1% 0.125W (1/8W) chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package. This thick film, moisture-resistant component operates across a temperature range of -55°C to 155°C and is ROHS3 compliant. The part is currently in active production status with 1,068 units available in inventory. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative qualified sources meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012F3833CS is determined by strict equivalence across the following critical parameters: resistance value (383 kOhms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected). All identified substitute parts meet these core electrical and mechanical requirements. Packaging format differences (Tape & Reel versus Cut Tape) do not affect functional equivalence but may influence procurement and assembly workflows. Automotive AEC-Q200 qualification present in certain substitutes represents an additional feature that does not preclude use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RC2012F3833CS (Samsung Electro-Mechanics), RC0805FR-07383KL (YAGEO), CRCW0805383KFKEA (Vishay Dale), and ERJ-6ENF3833V (Panasonic Electronic Components)—are functionally equivalent and maintain active production status. Each part satisfies ROHS3 compliance and REACH Unaffected regulatory requirements. The RC0805FR-07383KL offers the lowest seated height at 0.024" (0.60mm) and is available in the highest quantity (48,288 units). The CRCW0805383KFKEA provides the most compact profile at 0.020" (0.50mm) and includes AEC-Q200 automotive qualification. The ERJ-6ENF3833V also carries AEC-Q200 qualification with a seated height of 0.028" (0.70mm). Selection among these parts depends on specific application requirements regarding physical height constraints, supply availability, and whether automotive-grade qualification is mandated by design specifications.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07383KL replace RC2012F3833CS directly?

A: Yes. Both parts share identical electrical specifications (383 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C operating range) and package type (0805 / 2012 Metric). The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and a marginal height reduction (0.024" versus 0.026"). These differences do not affect functional compatibility in circuit applications.

Q: What is the significance of AEC-Q200 qualification on CRCW0805383KFKEA and ERJ-6ENF3833V?

A: AEC-Q200 is an automotive industry qualification standard. Parts bearing this certification have undergone additional reliability testing and are approved for automotive applications. Non-automotive applications do not require this qualification, but its presence does not restrict use in general-purpose circuits.

Q: Are there physical height differences that affect PCB assembly?

A: Yes. Seated heights vary: RC2012F3833CS (0.66mm), RC0805FR-07383KL (0.60mm), CRCW0805383KFKEA (0.50mm), and ERJ-6ENF3833V (0.70mm). In applications with tight vertical clearance constraints, the CRCW0805383KFKEA offers the most compact profile. Conversely, designs with no height restrictions can use any of the four parts without modification.

Q: Do packaging format differences (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects procurement, storage, and assembly logistics only. Electrical and mechanical performance remains identical regardless of whether the part is supplied on Tape & Reel or Cut Tape & Digi-Reel.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts—RC2012F3833CS, RC0805FR-07383KL, CRCW0805383KFKEA, and ERJ-6ENF3833V—are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part has the highest inventory availability?

A: RC0805FR-07383KL (YAGEO) has 48,288 units in stock, compared to 31,111 units for CRCW0805383KFKEA, 25,346 units for ERJ-6ENF3833V, and 1,068 units for the original RC2012F3833CS.
