RC1608F2R2CS Equivalent & Substitute Parts

Part Overview

The RC1608F2R2CS is a 2.2 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format. This surface mount device is rated for 0.1W (1/10W) power dissipation and features moisture-resistant construction with an operating temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, supply chain optimization, or specific application certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F2R2CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.2 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All four substitute parts (ERJ-3RQF2R2V, KTR03EZPF2R20, RC0603FR-072R2L, RMCF0603FT2R20) meet these mandatory parameters. Differences in temperature coefficient (±200ppm/°C versus ±300ppm/°C for the main part) and optional certifications (AEC-Q200 automotive qualification) represent secondary variations that do not prevent functional substitution within the specified electrical and mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3RQF2R2V replace RC1608F2R2CS in non-automotive applications?

A: Yes. The ERJ-3RQF2R2V meets all mandatory electrical and mechanical parameters for the RC1608F2R2CS. AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive designs. The improved temperature coefficient (±200ppm/°C) may provide performance benefits in temperature-sensitive circuits.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape (CT) and Digi-Reel® packaging provide components on cut tape segments, typically for lower-volume or manual assembly operations. The RC0603FR-072R2L is available in both formats; other substitutes use Tape & Reel exclusively.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts (ERJ-3RQF2R2V, KTR03EZPF2R20, RC0603FR-072R2L, RMCF0603FT2R20) carry ROHS3 compliance certification, matching the main part RC1608F2R2CS.

Q: Does the temperature coefficient difference affect circuit performance?

A: The main part RC1608F2R2CS has a temperature coefficient of ±300ppm/°C, while all substitute parts specify ±200ppm/°C. This means substitute parts exhibit lower resistance drift across the operating temperature range (-55°C to 155°C). For precision current-sensing or temperature-compensated circuits, the lower temperature coefficient of substitute parts may provide improved stability. For general-purpose applications, both specifications are functionally equivalent within the ±1% tolerance band.

Q: Which substitute part has the highest inventory availability?

A: RMCF0603FT2R20 (Stackpole Electronics Inc) has the highest inventory with 151,126 pcs in stock, followed by ERJ-3RQF2R2V (Panasonic) with 58,738 pcs. The main part RC1608F2R2CS has 861 pcs available.

Q: Can I use KTR03EZPF2R20 in high-voltage applications?

A: KTR03EZPF2R20 is specified with high-voltage capability as a feature. However, the provided parameters do not include maximum voltage ratings. Consult the manufacturer's detailed datasheet for specific voltage specifications before application in high-voltage circuits.

Q: Are all parts available in the same physical dimensions?

A: All parts conform to the 0603 (1608 Metric) package standard with dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm). RMCF0603FT2R20 specifies a slightly different length of 0.061" (1.55mm), which remains within standard 0603 package tolerances and does not affect PCB footprint compatibility.
