RC1608F2742CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F2742CS is a 27.4 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.1W (1/10W) power dissipation in a 0603 (1608 Metric) surface mount package. This component is classified as Active product status with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part is supplied in Cut Tape (CT) packaging with 895 pieces currently in stock inventory.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications permit the use of functionally identical components from different manufacturers that meet identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F2742CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27.4 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package type: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• Number of terminations: 2

All substitute parts listed below meet these mandatory parameters. Substitute parts are grouped into two categories:

Direct Substitutes: Parts with identical electrical specifications and standard industrial packaging formats (Cut Tape or Tape & Reel).

Similar Substitutes: Parts with identical electrical specifications but featuring additional automotive-grade certifications (AEC-Q200) or alternative packaging configurations. These parts are functionally equivalent and may be used in applications where the additional certification does not create design conflicts.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC1608F2742CS with any of the listed parts without circuit redesign?

A: Yes. All listed parts except CRCW060327K4FKTA share identical electrical parameters (27.4 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C operating range) and the same 0603 package footprint. Direct substitution is permissible at the component level without circuit modification.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies components in individual strips suitable for manual assembly or small-batch production. Tape & Reel packaging supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Both formats contain identical components; the difference is in manufacturing process compatibility and handling requirements.

Q: Why do some substitute parts have AEC-Q200 certification when the primary part does not?

A: AEC-Q200 is an automotive-grade qualification standard. Parts with this certification undergo additional testing and quality assurance beyond standard industrial requirements. A part with AEC-Q200 certification can be used in standard industrial applications without restriction; the certification simply indicates it meets higher reliability standards. Conversely, a part without AEC-Q200 certification should not be used in automotive applications requiring this qualification.

Q: Is ROHS3 compliance mandatory for all substitutes?

A: For new designs and applications subject to European Union Restriction of Hazardous Substances regulations, ROHS3 compliance is mandatory. The primary part RC1608F2742CS is ROHS3 compliant. Six of the seven substitute parts listed are ROHS3 compliant. CRCW060327K4FKTA is RoHS non-compliant and should be used only in legacy system maintenance where regulatory exemptions apply.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. All listed parts have MSL 1 rating, meaning they do not require special dry-storage conditions and can be stored under standard industrial conditions indefinitely without moisture absorption affecting performance.

Q: Can I mix different manufacturers' parts in the same circuit board assembly?

A: Yes. All listed substitute parts meet identical electrical and mechanical specifications. Mixing manufacturers on the same board is permissible from an engineering standpoint. However, manufacturing and quality control procedures may specify single-source components for traceability and consistency. Consult your manufacturing documentation before implementing multi-source component strategies.

Q: Which substitute part offers the best supply availability?

A: RMCF0603FT27K4 (Stackpole Electronics Inc) offers the highest inventory level at 1,110,458 pieces, followed by ERJ-3EKF2742V (Panasonic Electronic Components) at 145,175 pieces. Both parts are ROHS3 compliant with AEC-Q200 certification and available in Tape & Reel format suitable for automated assembly.
