Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F2670CS is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 267 Ohms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power ratings (0.5W or greater) while maintaining the same package footprint and thermal characteristics.

Identified Substitutes:

1. CRCW1210267RFKEA (Vishay Dale) – 0.5W rating with AEC-Q200 automotive qualification
2. ERJ-14NF2670U (Panasonic Electronic Components) – 0.5W rating with AEC-Q200 automotive qualification, Not For New Designs status

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC3225F2670CS): The Samsung Electro-Mechanics RC3225F2670CS maintains Active product status with standard industrial compliance. Selection is appropriate for general-purpose applications where moisture resistance and standard temperature performance are required.

First Alternative (CRCW1210267RFKEA): The Vishay Dale CRCW1210267RFKEA is suitable as a direct substitute with the following considerations: Active product status, higher power rating (0.5W) provides thermal margin, AEC-Q200 automotive qualification extends application scope, ROHS3 compliant. This part is recommended for applications requiring automotive-grade reliability or where thermal headroom is beneficial.

Secondary Alternative (ERJ-14NF2670U): The Panasonic Electronic Components ERJ-14NF2670U meets all electrical and mechanical compatibility requirements with AEC-Q200 automotive qualification. However, this part carries "Not For New Designs" product status, indicating manufacturer discontinuation trajectory. Selection is limited to legacy system support or where existing supply chain integration exists.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210267RFKEA replace RC3225F2670CS in existing designs?

A: Yes. Both parts share identical resistance (267 Ohms), tolerance (±1%), package (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and moisture sensitivity level (1). The CRCW1210267RFKEA has a higher power rating (0.5W vs. 0.333W), which is compatible with the same footprint and does not create electrical conflicts in circuits designed for the lower-rated part.

Q: Why does ERJ-14NF2670U show "Not For New Designs" status?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development and promotion of this part number. While the part remains electrically and mechanically compatible, it should not be selected for new product designs. Existing applications may continue using available inventory, but long-term supply cannot be guaranteed.

Q: Are there dimensional differences between these three parts?

A: All three parts use the 1210 (3225 Metric) package. Minor dimensional variations exist: RC3225F2670CS height is 0.66mm maximum, CRCW1210267RFKEA is 0.60mm maximum, and ERJ-14NF2670U is 0.70mm maximum. These variations remain within standard 1210 package tolerances and do not affect PCB layout or reflow compatibility.

Q: What is the significance of AEC-Q200 qualification on substitute parts?

A: AEC-Q200 is an automotive industry standard qualification for passive components. CRCW1210267RFKEA and ERJ-14NF2670U both carry this certification, indicating enhanced reliability testing and performance validation for automotive applications. The RC3225F2670CS does not specify this rating, making it suitable for general industrial use but not explicitly qualified for automotive environments.

Q: Can I use a higher power-rated resistor in place of the original?

A: Yes. Substituting a 0.5W-rated resistor for a 0.333W-rated resistor in the same package is electrically valid. The higher power rating provides additional thermal capacity without changing electrical behavior. Circuit performance remains unchanged, and thermal stress on the component is reduced.
