RC3225F106CS Equivalent & Substitute Parts

Part Overview

The RC3225F106CS is a 10 MOhms ±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, indicating unlimited moisture sensitivity protection.

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and compliance certifications. Substitute components must maintain identical resistance value, tolerance, power rating, package format, and operating temperature range to ensure direct functional replacement in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F106CS are qualified based on the following critical parameters:

Electrical Equivalence: Resistance value of 10 MOhms with ±1% tolerance, power rating of 0.333W (1/3W), and temperature coefficient of ±100ppm/°C must be maintained.

Mechanical Compatibility: Package format must be 1210 (3225 Metric) with identical physical dimensions and two terminations to ensure PCB footprint compatibility.

Environmental & Compliance Requirements: Operating temperature range of -55°C to 155°C, ROHS3 compliance, and MSL 1 rating must be preserved.

Composition: Thick film construction is required for functional equivalence.

The identified substitute part KTR25JZPF1005 from Rohm Semiconductor satisfies all these criteria while offering additional automotive-grade qualification (AEC-Q200) and high-voltage features.

Parameter Comparison

Engineering Selection Recommendations

Both the RC3225F106CS and KTR25JZPF1005 are Active products with full ROHS3 compliance and MSL 1 rating, confirming their suitability for current design implementations.

The RC3225F106CS from Samsung Electro-Mechanics is the primary component specification and remains the preferred selection for standard applications requiring the specified electrical and mechanical parameters.

The KTR25JZPF1005 from Rohm Semiconductor qualifies as a direct functional substitute. This part maintains all critical electrical specifications and package compatibility while offering additional automotive-grade qualification per AEC-Q200 and high-voltage features. The physical dimensions are equivalent within tolerance (width difference of 0.05mm is negligible for 1210 package applications).

Selection between these parts should be based on supply chain availability, cost considerations, and application-specific requirements for automotive qualification or high-voltage performance.

Frequently Asked Questions (FAQ)

Q: Can KTR25JZPF1005 be used as a direct replacement for RC3225F106CS?

A: Yes. Both parts share identical electrical specifications (10 MOhms ±1%, 0.333W), operate across the same temperature range (-55°C to 155°C), use thick film composition, and are packaged in the 1210 (3225 Metric) format. Physical dimensions are equivalent within standard manufacturing tolerances.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: resistance value (10 MOhms), tolerance (±1%), power rating (0.333W), package format (1210 / 3225 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1).

Q: Are there dimensional differences between these parts?

A: The length and height are identical (3.20mm and 0.65mm respectively). The width differs by 0.05mm (2.55mm versus 2.50mm), which is within standard PCB footprint tolerance for 1210 package applications and does not affect functional compatibility.

Q: What additional features does the KTR25JZPF1005 offer?

A: The KTR25JZPF1005 includes automotive-grade qualification (AEC-Q200) and high-voltage features beyond the base specification. These are supplementary capabilities that do not affect core substitution compatibility.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RC3225F106CS and KTR25JZPF1005 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the packaging format for each part?

A: RC3225F106CS is supplied in standard packaging. KTR25JZPF1005 is supplied in Tape & Reel (TR) format. Both use the 1210 (3225 Metric) package case.
