RC3216F17R8CS 17.8 Ohm 1% 1/4W 1206 Chip Resistor

Part Overview

The RC3216F17R8CS is a 17.8 ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 metric) surface mount package. This moisture-resistant resistor is rated for 0.25W (1/4W) power dissipation and operates across the -55°C to 155°C temperature range. The part maintains an active product status with 767 units currently in stock. Equivalent and substitute parts are necessary to accommodate supply chain variations, regional availability, and specific application requirements such as automotive qualification or extended packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RC3216F17R8CS is determined by the following critical parameters:

Electrical Parameters: Resistance (17.8 Ohms), tolerance (±1%), and power rating (0.25W) must be identical.

Mechanical Parameters: Package type (1206 / 3216 metric), physical dimensions, and termination count must match to ensure PCB assembly compatibility.

Environmental Parameters: Operating temperature range (-55°C ~ 155°C) and temperature coefficient (±100 ppm/°C) must be maintained.

Regulatory Compliance: RoHS3 compliance and MSL rating must satisfy design requirements.

The following substitute parts meet these criteria:

• CR1206-FX-17R8ELF (Bourns Inc.) – Direct substitute with identical electrical and thermal specifications
• RC1206FR-0717R8L (YAGEO) – Direct substitute with minor dimensional variation (3.10mm vs 3.20mm length)
• CRCW120617R8FKEA (Vishay Dale) – Direct substitute with automotive AEC-Q200 qualification
• ERJ-8ENF17R8V (Panasonic Electronic Components) – Direct substitute with automotive AEC-Q200 qualification (Not For New Designs)

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: CR1206-FX-17R8ELF (Bourns Inc.) or RC1206FR-0717R8L (YAGEO) are recommended for standard applications. Both parts maintain active product status and provide full compliance with RoHS3 and MSL 1 requirements. Selection between these two should be based on procurement availability and packaging requirements, as both are functionally equivalent.

Automotive Applications: CRCW120617R8FKEA (Vishay Dale) is the recommended substitute for designs requiring automotive qualification. This part carries AEC-Q200 certification and maintains active product status, making it suitable for automotive and harsh environment applications.

Legacy Applications: ERJ-8ENF17R8V (Panasonic Electronic Components) is available in the specified value but carries a "Not For New Designs" product status. This part should be used only for replacement and maintenance of existing designs where supply continuity is required.

Inventory Considerations: CR1206-FX-17R8ELF offers the highest stock availability (26,099 units), while RC3216F17R8CS (Samsung) has the lowest (767 units). Selection should account for project timelines and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can I use CRCW120617R8FKEA as a direct substitute for RC3216F17R8CS in non-automotive applications?

A: Yes. CRCW120617R8FKEA meets all electrical, thermal, and regulatory parameters required for the RC3216F17R8CS. The automotive AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive designs.

Q: What is the significance of the dimensional variation in RC1206FR-0717R8L (3.10mm vs 3.20mm length)?

A: The 0.1mm length difference falls within standard manufacturing tolerances for 1206 package resistors and does not impact PCB assembly, electrical performance, or thermal characteristics. Both dimensions are compatible with standard 1206 footprints.

Q: Why is ERJ-8ENF17R8V marked "Not For New Designs"?

A: This designation indicates that Panasonic is discontinuing active development and promotion of this part number. While the part remains functional and complies with all specifications, it should be reserved for maintenance and replacement of existing assemblies rather than new product development.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel packaging, which is standard for high-volume surface mount assembly. The original Samsung part packaging specification was not provided.

Q: What is MSL 1 (Unlimited) and does it matter for my application?

A: MSL (Moisture Sensitivity Level) 1 (Unlimited) means the component has no moisture-induced stress damage risk and requires no special handling or storage conditions. All parts listed, including the original, carry this rating.

Q: Can I mix different manufacturers' parts in the same PCB assembly?

A: Yes. All listed parts meet identical electrical and mechanical specifications and carry RoHS3 compliance. Mixing manufacturers is permissible from an engineering standpoint, though procurement may prefer single-source parts for inventory management.
