Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F243CS is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Resistance value: 24 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W) minimum
• Package / Case: 0201 (0603 Metric)
• Composition: Thick Film
• Operating temperature range: Must encompass or equal -55°C ~ 125°C
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• RoHS3 compliance: Required

Secondary Compatibility Factors:

• Temperature coefficient: ±250ppm/°C or lower (tighter tolerance acceptable)
• Termination count: 2 (standard for chip resistors)
• Supplier device package: 0201

Parts meeting all primary criteria are classified as direct substitutes. Parts with extended operating temperature ranges or improved temperature coefficients remain functionally compatible within the RC0603F243CS operating envelope.

Engineering Selection Recommendations

CRCW020124K0FKED (Vishay Dale) — Direct Substitute

The CRCW020124K0FKED meets all primary substitution criteria and is classified as a direct substitute for the RC0603F243CS. This part maintains identical resistance, tolerance, power rating, package dimensions, and MSL rating. The extended operating temperature range (-55°C ~ 155°C) and improved temperature coefficient (±100ppm/°C) provide enhanced performance margins within the RC0603F243CS application envelope. Product status is Active with full RoHS3 compliance. Inventory availability is 30,314 units. Packaging is supplied as Tape & Reel (TR), suitable for automated assembly operations.

MCR006YRTF2402 (Rohm Semiconductor) — Functional Equivalent with Availability Limitation

The MCR006YRTF2402 satisfies all primary electrical and mechanical substitution parameters. Resistance, tolerance, power rating, package dimensions, temperature coefficient, and MSL rating are identical to the RC0603F243CS. Operating temperature range matches at -55°C ~ 125°C. RoHS3 compliance is confirmed. However, product status is listed as Discontinued at DiGi Electronics, indicating limited future availability. Current inventory is 1,064 units. Packaging is Cut Tape (CT) & Digi-Reel®. This part is suitable for immediate replacement applications but should not be selected for long-term production programs requiring sustained component availability.

Frequently Asked Questions (FAQ)

Q: Can CRCW020124K0FKED replace RC0603F243CS in all applications?

A: Yes. The CRCW020124K0FKED is a direct substitute meeting all electrical specifications (24 kOhms ±1%, 0.05W), mechanical dimensions (0201 package), and compliance requirements (RoHS3, MSL 1). The improved temperature coefficient (±100ppm/°C vs. ±250ppm/°C) and extended operating range (-55°C ~ 155°C vs. -55°C ~ 125°C) provide equivalent or superior performance in the RC0603F243CS operating envelope.

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

A: Cut Tape (CT) packaging supplies components in individual strips suitable for manual assembly or small-volume applications. Tape & Reel (TR) packaging supplies components on continuous reels optimized for automated pick-and-place assembly equipment. Both packaging formats contain identical components; selection depends on assembly process requirements.

Q: Why is MCR006YRTF2402 listed as discontinued?

A: MCR006YRTF2402 is marked as Discontinued at DiGi Electronics, indicating the distributor has ceased active procurement. This status reflects supply chain decisions rather than component defect. The part remains functionally equivalent but should not be specified for new designs or production programs requiring long-term component availability.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC0603F243CS, CRCW020124K0FKED, and MCR006YRTF2402 are all ROHS3 Compliant with REACH Unaffected status and EAR99 export classification.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part does not require special moisture-controlled storage, handling, or reflow procedures. All three parts carry this rating.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. CRCW020124K0FKED (Tape & Reel) is optimized for automated assembly. RC0603F243CS and MCR006YRTF2402 (Cut Tape) are suitable for manual or semi-automated placement. All three parts occupy identical footprints and electrical performance within the specified operating range.
