Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC0603J243CS are classified into two categories based on electrical parameter compatibility:

Upgrade Substitutes maintain all primary electrical specifications (24 kOhms resistance, 0.05W power rating, 0201 package) while offering improved tolerance specifications (±1% versus ±5%). These parts are direct functional upgrades suitable for applications requiring tighter resistance tolerances. Upgrade substitutes include RC0603F243CS (Samsung Electro-Mechanics) and CRCW020124K0FKED (Vishay Dale).

Similar Substitutes maintain all primary electrical specifications and package dimensions but may differ in secondary performance parameters such as temperature coefficient or operating temperature range. The MCR006YRTF2402 (Rohm Semiconductor) is classified as a similar substitute with discontinued product status at DiGi Electronics.

Substitution eligibility is determined by the following criteria:

• Identical resistance value (24 kOhms)
• Equal or superior tolerance specification (±1% acceptable for ±5% requirement)
• Identical or superior power rating (0.05W minimum)
• Identical package / case (0201 / 0603 Metric)
• Identical composition (Thick Film)
• Compatible operating temperature range (minimum -55°C ~ 125°C)
• RoHS3 compliance maintained
• MSL 1 rating maintained

Parameter Comparison

Engineering Selection Recommendations

For Active Production Applications:

RC0603F243CS (Samsung Electro-Mechanics) is the preferred upgrade substitute when tighter tolerance specifications (±1%) are required. This part maintains identical operating temperature range, temperature coefficient, and packaging format compatibility while offering superior tolerance performance. Both parts are Active status with equivalent compliance certifications.

CRCW020124K0FKED (Vishay Dale) is an alternative upgrade substitute offering the lowest temperature coefficient (±100ppm/°C) and extended operating temperature range (-55°C ~ 155°C). This part is suitable for applications requiring enhanced thermal stability and higher temperature operation. Inventory availability is significantly higher (30314 pieces), supporting high-volume production requirements. Packaging format differs (Tape & Reel supplied), which may require process adjustment.

For Legacy or Constrained Applications:

MCR006YRTF2402 (Rohm Semiconductor) is available as a similar substitute with equivalent electrical performance. However, this part is classified as Discontinued at DiGi Electronics, limiting long-term supply reliability. Selection of this part should be restricted to applications where existing inventory is available or where alternative sources have confirmed continued availability.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical mechanical compatibility with the RC0603J243CS. No additional qualification or testing is required based on provided compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can RC0603F243CS directly replace RC0603J243CS in existing designs?

A: Yes. RC0603F243CS is a direct functional upgrade. The ±1% tolerance specification is superior to the ±5% requirement of RC0603J243CS. All electrical parameters, package dimensions, operating temperature range, and compliance certifications are identical or equivalent. The only difference is packaging format (Cut Tape versus Tape & Reel), which affects handling and assembly processes but not component performance.

Q: What is the difference between the upgrade and similar substitute categories?

A: Upgrade substitutes (RC0603F243CS and CRCW020124K0FKED) offer improved tolerance specifications (±1% versus ±5%) while maintaining all other primary electrical parameters. Similar substitutes (MCR006YRTF2402) maintain equivalent electrical performance but may differ in secondary parameters such as temperature coefficient or product status. All three are electrically compatible with RC0603J243CS.

Q: Does CRCW020124K0FKED offer any performance advantages over RC0603F243CS?

A: CRCW020124K0FKED offers two specific advantages: lower temperature coefficient (±100ppm/°C versus ±250ppm/°C) and extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C). These characteristics make it suitable for applications requiring enhanced thermal stability or operation at elevated temperatures. Tolerance specification (±1%) is equivalent to RC0603F243CS.

Q: Why is MCR006YRTF2402 classified as discontinued?

A: MCR006YRTF2402 is marked as Discontinued at DiGi Electronics, indicating that this distributor no longer actively stocks or supports this part. However, 1064 pieces remain in current inventory. For new designs, RC0603F243CS or CRCW020124K0FKED are recommended. MCR006YRTF2402 should be considered only when existing inventory is available or alternative supply sources have confirmed availability.

Q: Are there packaging format considerations when substituting these parts?

A: Yes. RC0603J243CS is supplied in Tape & Reel (TR) format. RC0603F243CS is supplied in Cut Tape (CT) format, and CRCW020124K0FKED is supplied in Tape & Reel (TR) format. Cut Tape format requires different handling and may require process adjustment in automated assembly environments. Verify packaging compatibility with your assembly equipment and supply chain requirements before implementation.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts (RC0603F243CS, CRCW020124K0FKED, and MCR006YRTF2402) are ROHS3 compliant with MSL 1 (Unlimited) rating. REACH status is Unaffected for all parts. No additional compliance qualification is required for substitution.

Q: What is the primary reason to select CRCW020124K0FKED over other substitutes?

A: CRCW020124K0FKED is selected when applications require extended operating temperature range (-55°C ~ 155°C) or superior temperature coefficient stability (±100ppm/°C). Additionally, inventory availability is substantially higher (30314 pieces), supporting high-volume production. This part is manufactured by Vishay Dale, a major resistor supplier with established supply chain reliability.
