Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

• Resistance Value: 24.9 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Number of Terminations: 2 (exact match required)

Substitute parts are grouped into two categories based on power rating:

Category A - Standard 0.125W (1/8W) Rating: RMCF0805FT24R9, CRCW080524R9FKEA, CRCW080524R9FKTA, ERJ-6ENF24R9V, RC0805FR-0724R9L

Category B - Enhanced 0.5W (1/2W) Rating: CRCW080524R9FKEAHP, RCS080524R9FKEA

All substitute parts maintain identical resistance, tolerance, package dimensions, composition, temperature coefficient, and operating temperature range as the primary part.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliant Applications: RMCF0805FT24R9, CRCW080524R9FKEA, CRCW080524R9FKEAHP, ERJ-6ENF24R9V, RC0805FR-0724R9L, and RCS080524R9FKEA all meet ROHS3 compliance requirements. CRCW080524R9FKTA is RoHS non-compliant and should not be used in applications requiring RoHS certification.

For Automotive Applications: RMCF0805FT24R9, CRCW080524R9FKEA, CRCW080524R9FKEAHP, ERJ-6ENF24R9V, and RCS080524R9FKEA carry Automotive AEC-Q200 certification. These parts are suitable for automotive-grade applications.

For Standard Industrial Applications: RC0805FR-0724R9L offers moisture-resistant thick film composition without automotive certification, suitable for general industrial use.

For Enhanced Power Dissipation: CRCW080524R9FKEAHP and RCS080524R9FKEA provide 0.5W (1/2W) power rating with pulse withstanding capability, compared to the standard 0.125W (1/8W) rating of the primary part and other substitutes.

For Supply Availability: ERJ-6ENF24R9V offers the highest inventory level (92,775 units), followed by RMCF0805FT24R9 (53,934 units) and RCS080524R9FKEA (14,825 units).

Frequently Asked Questions (FAQ)

Q: Can CRCW080524R9FKEAHP be used as a direct replacement for RMCS0805FT24R9?

A: CRCW080524R9FKEAHP is electrically compatible in terms of resistance, tolerance, package, and operating temperature range. However, it features a higher power rating (0.5W vs. 0.125W) and pulse withstanding capability. It is physically compatible with the 0805 package footprint. Use is appropriate when enhanced power dissipation or pulse withstanding is required or acceptable in the circuit design.

Q: What is the difference between the standard 0.125W and enhanced 0.5W power ratings?

A: The 0.125W (1/8W) rating applies to RMCS0805FT24R9, RMCF0805FT24R9, CRCW080524R9FKEA, CRCW080524R9FKTA, ERJ-6ENF24R9V, and RC0805FR-0724R9L. The 0.5W (1/2W) rating applies to CRCW080524R9FKEAHP and RCS080524R9FKEA. Higher power rating indicates greater capability to dissipate thermal energy without exceeding maximum operating temperature limits.

Q: Is CRCW080524R9FKTA suitable for RoHS-regulated applications?

A: No. CRCW080524R9FKTA is marked as RoHS non-compliant and REACH Affected. It should not be used in applications requiring RoHS3 compliance or REACH compliance.

Q: Are all substitute parts available in the same packaging format?

A: Most substitute parts are available in Tape & Reel (TR) packaging. ERJ-6ENF24R9V is available in Cut Tape (CT) & Digi-Reel® packaging. Verify packaging requirements with your procurement specifications before selection.

Q: What certifications apply to automotive-grade substitutes?

A: RMCF0805FT24R9, CRCW080524R9FKEA, CRCW080524R9FKEAHP, ERJ-6ENF24R9V, and RCS080524R9FKEA all carry Automotive AEC-Q200 certification. This certification indicates qualification for automotive applications per AEC-Q200 standards.

Q: Can RC0805FR-0724R9L be used in moisture-sensitive environments?

A: RC0805FR-0724R9L features moisture-resistant thick film composition. All listed parts, including the primary RMCS0805FT24R9, carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
