RC3216F18R7CS Equivalent & Substitute Parts

Part Overview

The RC3216F18R7CS is a 18.7 Ohm ±1% 0.25W (1/4W) chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film, moisture-resistant resistor operates across a temperature range of -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate components with specific certifications or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3216F18R7CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 18.7 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All identified substitute parts meet these mandatory parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in product status or certifications do not prevent functional substitution but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-0718R7L (YAGEO): This part is functionally equivalent to the RC3216F18R7CS with active product status. It is supplied in Tape & Reel packaging and maintains all critical electrical and thermal specifications. Selection is appropriate for applications requiring standard moisture-resistant thick film resistors without automotive certification requirements.

CRCW120618R7FKEA (Vishay Dale): This part meets all mandatory electrical parameters and includes Automotive AEC-Q200 certification. It is supplied in Tape & Reel packaging and maintains active product status. Selection is appropriate for automotive applications or designs requiring AEC-Q200 qualified components.

ERJ-8ENF18R7V (Panasonic Electronic Components): This part meets all mandatory electrical parameters and includes Automotive AEC-Q200 certification. However, its product status is listed as "Not For New Designs." This designation indicates the manufacturer does not recommend this part for new design implementations. Selection should be limited to legacy system support or replacement applications where existing designs already incorporate this part number.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-0718L be used as a direct replacement for RC3216F18R7CS?

A: Yes. Both parts share identical resistance (18.7 Ohms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and RoHS compliance. The primary difference is packaging format (Tape & Reel versus bulk) and manufacturer. Electrical performance is equivalent.

Q: What is the difference between the Samsung and YAGEO versions?

A: The RC3216F18R7CS (Samsung) and RC1206FR-0718R7L (YAGEO) are electrically and thermally identical. Both are moisture-resistant thick film resistors with identical specifications. The YAGEO part is supplied in Tape & Reel packaging, which is standard for automated assembly processes, while the Samsung part is supplied in bulk packaging.

Q: Should I use the Panasonic ERJ-8ENF18R7V for new designs?

A: No. The ERJ-8ENF18R7V carries a "Not For New Designs" product status designation from Panasonic. This part should be used only for replacement or legacy system support. For new designs, select either the YAGEO RC1206FR-0718R7L or the Vishay Dale CRCW120618R7FKEA.

Q: What is the advantage of the Vishay Dale CRCW120618R7FKEA?

A: The CRCW120618R7FKEA includes Automotive AEC-Q200 certification, which qualifies it for automotive applications. If your design requires automotive-grade components or operates in automotive environments, this part is the appropriate selection. All other electrical specifications remain identical to the standard versions.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within the 1206 package specification. The RC3216F18R7CS and CRCW120618R7FKEA measure 0.126" L × 0.063" W (3.20mm × 1.60mm), while the RC1206FR-0718R7L measures 0.122" L × 0.063" W (3.10mm × 1.60mm). Height variations range from 0.024" to 0.028" (0.60mm to 0.70mm). These variations remain within 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Can I mix these parts in the same production batch?

A: Yes, provided your design does not require specific certifications. All four parts are electrically and thermally equivalent. However, if your application requires AEC-Q200 certification, use only the CRCW120618R7FKEA or ERJ-8ENF18R7V. For new designs, avoid mixing active and "Not For New Designs" parts.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All four substitute parts carry this rating, eliminating moisture-related supply chain constraints.
