Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F24R9CS are classified into two categories based on electrical and mechanical parameter alignment:

Direct Substitutes (Identical Electrical & Mechanical Specifications): Parts that match all critical parameters: 24.9 Ohms resistance, ±1% tolerance, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and MSL 1 moisture sensitivity. These parts are interchangeable without circuit redesign.

Similar Substitutes (Matching Core Specifications with Variations): Parts that maintain identical resistance, tolerance, package, and temperature range but differ in one or more secondary parameters such as power rating, automotive certification (AEC-Q200), or RoHS compliance status. Selection depends on application requirements and compliance mandates.

Key Parameters Determining Substitution:

• Resistance value and tolerance (24.9 Ohms ±1%)
• Power rating (0.125W minimum for direct substitution)
• Package format (0805 / 2012 Metric)
• Temperature coefficient (±100ppm/°C)
• Operating temperature range (-55°C ~ 155°C)
• Moisture sensitivity level (MSL 1)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required):

Select CR0805-FX-24R9ELF (Bourns Inc.), RC0805FR-0724R9L (YAGEO), or MCR10ERTF24R9 (Rohm Semiconductor) when direct electrical and mechanical equivalence is required. These parts maintain identical 0.125W power rating, ±1% tolerance, and ROHS3 compliance status matching the RC2012F24R9CS specification.

For Automotive Applications:

ERJ-6ENF24R9V (Panasonic), KTR10EZPF24R9 (Rohm), RMCF0805FT24R9 (Stackpole), CRCW080524R9FKEA (Vishay Dale), and RCS080524R9FKEA (Vishay Dale) are qualified to AEC-Q200 automotive standards. These substitutes are suitable for automotive circuit designs requiring component qualification documentation.

For High Voltage Applications:

KTR10EZPF24R9 (Rohm Semiconductor) includes high voltage capability in addition to AEC-Q200 automotive qualification, providing enhanced performance margin in high voltage circuit environments.

For Pulse Withstanding Applications:

CRCW080524R9FKEAHP (Vishay Dale) and RCS080524R9FKEA (Vishay Dale) feature pulse withstanding characteristics with 0.5W power rating, suitable for circuits experiencing transient overvoltage conditions. Note: These parts have higher power ratings than the original specification.

Compliance Considerations:

CRCW080524R9FKTA (Vishay Dale) is RoHS non-compliant and REACH affected. This part is not recommended for new designs or applications requiring regulatory compliance with ROHS3 standards.

Product Status:

MCR10ERTF24R9 (Rohm Semiconductor) is discontinued at DiGi Electronics. While functionally equivalent, long-term availability is not assured. Active status alternatives are preferred for production designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC2012F24R9CS with CRCW080524R9FKEAHP?

A: CRCW080524R9FKEAHP is electrically compatible in terms of resistance value, tolerance, and package format. However, it has a 0.5W power rating compared to the original 0.125W specification. This higher power rating is acceptable for direct substitution in most applications, as the component can handle the same current and voltage conditions with additional thermal margin. Verify circuit design does not depend on the lower power rating specification.

Q: What is the difference between direct substitutes and similar substitutes?

A: Direct substitutes match all electrical parameters including power rating (0.125W), tolerance (±1%), and compliance status (ROHS3). Similar substitutes maintain core specifications but may differ in power rating, automotive certification, or compliance status. Selection depends on application requirements and regulatory mandates.

Q: Are automotive-qualified parts (AEC-Q200) compatible with non-automotive applications?

A: Yes. AEC-Q200 qualified parts such as ERJ-6ENF24R9V, KTR10EZPF24R9, and RMCF0805FT24R9 meet or exceed standard commercial specifications. These parts are suitable for any application requiring the specified 24.9 Ohm ±1% 0.125W 0805 resistor, with the added benefit of automotive qualification documentation.

Q: Why is MCR10ERTF24R9 listed as discontinued?

A: MCR10ERTF24R9 is marked as discontinued at DiGi Electronics, indicating limited future availability. While currently in stock (1050 Pcs), this part should not be selected for new production designs. Active status alternatives such as CR0805-FX-24R9ELF or RC0805FR-0724R9L are recommended for long-term supply assurance.

Q: Can I use RCS080524R9FKEA or CRCW080524R9FKEAHP as direct replacements?

A: These parts have 0.5W power ratings versus the original 0.125W specification. They are functionally compatible and provide additional thermal capability. However, they are not direct electrical equivalents due to the power rating difference. Use only if circuit design permits higher power rating components or if additional thermal margin is beneficial.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitute parts maintain MSL 1 classification, ensuring compatibility with standard manufacturing and storage procedures.

Q: Are there package dimension differences between substitute parts?

A: All substitute parts use 0805 (2012 Metric) package format with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height variations range from 0.020" to 0.028" (0.50mm to 0.70mm), which are within standard PCB assembly tolerances and do not affect mechanical compatibility or placement.

Q: Which substitute offers the best availability?

A: RMCF0805FT24R9 (Stackpole Electronics) has the highest inventory at 53,934 Pcs. ERJ-6ENF24R9V (Panasonic) follows with 92,775 Pcs. Both parts are Active status with ROHS3 compliance and suitable for immediate production use.

Q: Is CRCW080524R9FKTA suitable for new designs?

A: CRCW080524R9FKTA is RoHS non-compliant and REACH affected. This part does not meet current regulatory requirements for new product designs in most markets. ROHS3 compliant alternatives such as CRCW080524R9FKEA are recommended instead.
