RC3225F2673CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F2673CS is a 267 kOhms ±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 based on matching electrical specifications (resistance value, tolerance, temperature coefficient) and mechanical compatibility (package size, termination count) while accounting for variations in power rating and application-specific certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RC3225F2673CS is determined by the following mandatory parameters:

Electrical Equivalence Requirements:

• Resistance value: 267 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Mechanical Compatibility Requirements:

• Package format: 1210 (3225 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Allowable Variations:

• Power rating: Substitute parts may have equal or higher power ratings (0.5W acceptable for 0.333W applications)
• Packaging format: Tape & Reel acceptable as functional equivalent to bulk packaging
• Application certifications: Automotive AEC-Q200 certification is an enhancement, not a restriction

The identified substitute parts AC1210FR-07267KL and ERJ-14NF2673U meet all mandatory electrical and mechanical parameters while offering increased power dissipation capability (0.5W vs. 0.333W).

Parameter Comparison

Engineering Selection Recommendations

AC1210FR-07267KL (YAGEO) - Upgrade Substitute:

This part is the preferred substitute for new designs and production applications. It maintains all electrical and mechanical equivalence to the RC3225F2673CS while providing enhanced power dissipation (0.5W vs. 0.333W). The component carries Active product status and includes AEC-Q200 automotive qualification, making it suitable for both commercial and automotive-grade applications. ROHS3 compliance and MSL 1 rating are maintained.

ERJ-14NF2673U (Panasonic) - Similar Substitute:

This part meets all electrical and mechanical requirements and carries AEC-Q200 automotive certification. However, the product status is listed as "Not For New Designs," restricting its use to legacy system support or replacement applications only. For new product development, AC1210FR-07267KL is the recommended choice.

Both substitute parts are functionally compatible with the RC3225F2673CS in applications where the original component is specified, provided the circuit design accommodates the higher power rating without adverse effects.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-07267KL replace RC3225F2673CS in existing designs?

A: Yes. The AC1210FR-07267KL is electrically and mechanically equivalent. The increased power rating (0.5W vs. 0.333W) does not create compatibility issues in circuits designed for the original 0.333W component. Physical dimensions are within acceptable tolerance for 1210 package format.

Q: What is the difference between the two substitute parts?

A: Both AC1210FR-07267KL and ERJ-14NF2673U meet the electrical and mechanical specifications. The primary distinction is product status: AC1210FR-07267KL is Active (suitable for new designs), while ERJ-14NF2673U is Not For New Designs (legacy support only). Both carry AEC-Q200 automotive certification.

Q: Are there packaging differences between these parts?

A: The RC3225F2673CS is supplied in bulk packaging, while both substitute parts are supplied in Tape & Reel (TR) format. This is a packaging format difference only and does not affect component functionality or electrical performance.

Q: Do all three parts have identical physical dimensions?

A: The parts are dimensionally similar within the 1210 package specification. Minor variations exist: RC3225F2673CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm), AC1210FR-07267KL measures 0.122" L x 0.102" W (3.10mm x 2.60mm), and ERJ-14NF2673U measures 0.126" L x 0.098" W (3.20mm x 2.50mm). These variations are within standard 1210 package tolerances and do not affect PCB layout compatibility.

Q: Is moisture resistance maintained across all three parts?

A: Yes. The RC3225F2673CS specifies moisture-resistant construction. AC1210FR-07267KL explicitly includes moisture-resistant features. ERJ-14NF2673U does not explicitly state moisture resistance in the provided specifications. All three parts maintain MSL 1 (Unlimited) rating.

Q: Can ERJ-14NF2673U be used in new product designs?

A: No. The ERJ-14NF2673U carries a "Not For New Designs" product status designation. This part is restricted to replacement and legacy support applications only. For new designs, AC1210FR-07267KL is the appropriate substitute.
