Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F2492CS is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 24.9 kOhms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Secondary Consideration:

• Power rating: Substitute parts rated at 0.5W (1/2W) exceed the original 0.333W (1/3W) specification and are acceptable for direct substitution in applications where the original power rating is sufficient, as higher-rated components provide equivalent or superior performance in the same package footprint.

All identified substitute parts meet these criteria and maintain mechanical and electrical compatibility with the RC3225F2492CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW121024K9FKEA (Vishay Dale) and RMCF1210FT24K9 (Stackpole Electronics Inc) are both classified as Active products and provide direct electrical and mechanical equivalence to the RC3225F2492CS. Both parts are ROHS3 compliant and feature automotive AEC-Q200 qualification, which exceeds the original part's general-purpose classification. These substitutes are suitable for new designs and ongoing production.

Secondary Substitute (Not For New Designs):

ERJ-14NF2492U (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status designation. This part is suitable for replacement and repair applications only and should not be selected for new design implementations.

Packaging Considerations:

The RC3225F2492CS is supplied in bulk packaging. Substitute parts are available in Tape & Reel (TR) format (CRCW121024K9FKEA, ERJ-14NF2492U) or Cut Tape (CT) format (RMCF1210FT24K9), which may require adjustment to procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can CRCW121024K9FKEA replace RC3225F2492CS directly?

A: Yes. Both parts share identical resistance (24.9 kOhms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The CRCW121024K9FKEA has a higher power rating (0.5W vs. 0.333W), which does not prevent substitution. Both are ROHS3 compliant and have MSL 1 rating.

Q: What is the difference between the power ratings of these parts?

A: The RC3225F2492CS is rated at 0.333W (1/3W), while CRCW121024K9FKEA, ERJ-14NF2492U, and RMCF1210FT24K9 are rated at 0.5W (1/2W). A higher power rating indicates greater thermal dissipation capability in the same physical package. Substituting a higher-rated part for a lower-rated part is acceptable when the application's actual power dissipation does not exceed the original specification.

Q: Why is ERJ-14NF2492U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued active development and promotion of this part number. While the part remains functionally equivalent and suitable for repair and replacement, it should not be selected for new product designs where alternative active parts are available.

Q: Are there packaging format differences between these substitutes?

A: Yes. The RC3225F2492CS is supplied in bulk packaging. CRCW121024K9FKEA and ERJ-14NF2492U are supplied in Tape & Reel (TR) format, while RMCF1210FT24K9 is supplied in Cut Tape (CT) format. Packaging format selection depends on assembly equipment compatibility and procurement requirements.

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

A: All parts listed are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. CRCW121024K9FKEA and RMCF1210FT24K9 carry automotive AEC-Q200 qualification, which provides additional reliability assurance beyond the original RC3225F2492CS specification.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided the assembly process and equipment support the substitute part's packaging format. The mechanical dimensions (length, width, height) are equivalent across all parts, and the electrical specifications are identical or superior. Verify that procurement and assembly workflows accommodate the packaging format of the selected substitute.
