RC3225F26R1CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F26R1CS is a 26.1 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or application-specific certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F26R1CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 26.1 Ohms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: The RC3225F26R1CS is rated at 0.333W (1/3W). Substitute parts rated at 0.5W (1/2W) or higher are acceptable as they provide equal or greater power dissipation capability within the same package footprint.

All identified substitute parts maintain identical resistance, tolerance, package dimensions, thermal characteristics, and compliance certifications. Differences in power rating represent an uprating that does not compromise compatibility or performance in applications designed for the original specification.

Engineering Selection Recommendations

Primary Selection (Active Status, General Applications):

• CRCW121026R1FKEA (Vishay Dale): Active product status with AEC-Q200 automotive qualification. Suitable for applications requiring automotive-grade reliability and extended supply chain availability.
• RMCF1210FT26R1 (Stackpole Electronics Inc): Active product status with AEC-Q200 automotive qualification. Provides alternative sourcing from established automotive-qualified manufacturer.

Secondary Selection (Legacy Applications):

• ERJ-14NF26R1U (Panasonic Electronic Components): Marked as "Not For New Designs" but remains available with AEC-Q200 qualification. Use only in existing production lines or legacy system maintenance where design changes are not feasible.

Selection Criteria:

• For new designs: Select from CRCW121026R1FKEA or RMCF1210FT26R1 based on supplier availability and lead time.
• For automotive applications: All three substitute parts carry AEC-Q200 certification; RC3225F26R1CS does not specify automotive qualification.
• For general industrial applications: RC3225F26R1CS remains the primary choice if inventory is available; substitutes are functionally equivalent.
• All parts maintain identical electrical performance within specified tolerance and temperature operating range.

Frequently Asked Questions (FAQ)

Q: Can CRCW121026R1FKEA replace RC3225F26R1CS directly? A: Yes. Both parts share identical resistance (26.1 Ohms), tolerance (±1%), package (1210), composition (thick film), and operating temperature range (-55°C to 155°C). The CRCW121026R1FKEA is rated at 0.5W versus the RC3225F26R1CS at 0.333W; this higher power rating is compatible with all applications designed for the original part.

Q: What is the difference between the 0.333W and 0.5W power ratings? A: The RC3225F26R1CS is rated for 0.333W (1/3W) power dissipation. Substitute parts rated at 0.5W (1/2W) can dissipate more power in the same package footprint. This represents an uprating and does not create compatibility issues; the substitute will perform identically or better in any application designed for the original specification.

Q: Are the physical dimensions identical between all parts? A: Dimensions are functionally equivalent within manufacturing tolerance. The RC3225F26R1CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" max height. Substitute parts measure 0.126" L x 0.098" W (3.20mm x 2.50mm) with heights ranging from 0.024" to 0.028". These minor variations fall within standard PCB layout tolerances for 1210 package components.

Q: Why is ERJ-14NF26R1U marked "Not For New Designs"? A: This designation indicates Panasonic has discontinued active development and promotion of this product line. While the part remains available and functionally equivalent, it is recommended for existing production support only. For new designs, select CRCW121026R1FKEA or RMCF1210FT26R1.

Q: Do all substitute parts have the same moisture sensitivity level? A: Yes. All parts, including the RC3225F26R1CS and all three substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are all parts RoHS3 compliant? A: Yes. The RC3225F26R1CS and all substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: Which substitute part should I choose for automotive applications? A: All three substitute parts (CRCW121026R1FKEA, ERJ-14NF26R1U, and RMCF1210FT26R1) carry AEC-Q200 automotive qualification. The RC3225F26R1CS does not specify automotive certification. For automotive applications, select from the qualified substitutes based on availability and lead time.
