Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F3483CS is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 348 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

Allowable Variation:

• Power rating may exceed the original specification (0.333W minimum required)
• Physical dimensions may vary within standard 1210 package tolerances
• Additional certifications (such as AEC-Q200) do not disqualify substitution

The CRCW1210348KFKEA from Vishay Dale meets all mandatory parameters and qualifies as a direct substitute. This part maintains identical electrical specifications while providing a higher power rating (0.5W vs. 0.333W) and automotive-grade certification.

Parameter Comparison

Engineering Selection Recommendations

The CRCW1210348KFKEA qualifies as a direct substitute for the RC3225F3483CS based on electrical and mechanical parameter equivalence. Both components maintain identical resistance value, tolerance, temperature coefficient, and operating temperature range. The substitute part carries ROHS3 compliance and REACH unaffected status, matching the original specification requirements.

The higher power rating of the CRCW1210348KFKEA (0.5W vs. 0.333W) provides additional thermal margin in circuit applications. The automotive AEC-Q200 certification of the substitute part indicates enhanced reliability screening and is not a limiting factor for general industrial or consumer applications.

Physical dimensions remain within 1210 package standard tolerances, ensuring PCB footprint compatibility. Both parts utilize thick film composition with identical moisture sensitivity classification, supporting equivalent performance in standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can the CRCW1210348KFKEA replace the RC3225F3483CS in any application?

A: Yes, the CRCW1210348KFKEA meets all mandatory electrical and mechanical parameters. The higher power rating (0.5W vs. 0.333W) is compatible with circuits designed for the original 0.333W specification. PCB footprint compatibility is maintained within 1210 package standards.

Q: What is the significance of the higher power rating in the substitute part?

A: The 0.5W rating of the CRCW1210348KFKEA provides additional thermal dissipation capacity compared to the 0.333W original specification. This does not affect circuit operation but offers increased safety margin in power dissipation scenarios.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The substitute part carries additional automotive AEC-Q200 certification, which indicates enhanced reliability screening but does not restrict use in non-automotive applications.

Q: Do the physical dimensions differ between these parts?

A: Both parts conform to the 1210 (3225 Metric) package standard. Dimensional variations fall within standard package tolerances: RC3225F3483CS measures 3.20mm x 2.55mm x 0.66mm maximum height; CRCW1210348KFKEA measures 3.20mm x 2.50mm x 0.60mm maximum height. These differences are within acceptable PCB assembly tolerances.

Q: Is the moisture resistance feature of the original part replicated in the substitute?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating equivalent moisture handling capability. The original part explicitly lists moisture resistance as a feature; the substitute achieves equivalent performance through identical MSL classification.

Q: What packaging formats are available for the substitute part?

A: The CRCW1210348KFKEA is supplied in Tape & Reel (TR) format, differing from the original part's packaging specification. Verify packaging requirements for your procurement and assembly processes.
