RC3216F3923CS 392kΩ 1% 1/4W 1206 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RC3216F3923CS is a 392 kOhms ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The RC series resistor is designed for general-purpose applications requiring stable resistance values across industrial temperature ranges. Substitute parts are necessary when primary inventory is unavailable, when specific certifications (such as AEC-Q200 automotive qualification) are required, or when alternative supplier sourcing is preferred for supply chain optimization.

Engineering Selection Recommendations

Primary Selection (Active Status, General Purpose): RC1206FR-07392KL (YAGEO) is the preferred substitute for the RC3216F3923CS. Both components share identical electrical specifications, matching height profile (0.026" / 0.65mm), and Active product status. YAGEO inventory availability (258,248 pcs) provides supply chain reliability. This selection is appropriate for non-automotive applications requiring standard industrial compliance.

Alternative Selection (Active Status, High Inventory): CR1206-FX-3923ELF (Bourns Inc.) provides equivalent electrical performance with Active product status. Height variation (0.030" / 0.75mm) remains within 1206 package tolerance and does not impact PCB assembly or reflow processes. Suitable for applications where Bourns supplier qualification is preferred.

Automotive Applications (AEC-Q200 Certification Required): RMCF1206FT392K (Stackpole Electronics Inc.) or CRCW1206392KFKEA (Vishay Dale) are specified for automotive-grade applications requiring AEC-Q200 qualification. Both maintain identical electrical parameters and operating temperature range. CRCW1206392KFKEA offers lower height profile (0.024" / 0.60mm) for space-constrained designs. RMCF1206FT392K provides alternative supplier qualification.

High-Voltage Automotive Applications: KTR18EZPF3923 (Rohm Semiconductor) combines AEC-Q200 automotive certification with high-voltage design features. Selection is appropriate when high-voltage stress conditions are present in automotive circuit designs.

Legacy System Support (Not For New Designs): ERJ-8ENF3923V (Panasonic Electronic Components) maintains full electrical equivalence but carries "Not For New Designs" status. This component is suitable only for replacement in existing systems or legacy product support where original specification continuity is required.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07392KL (YAGEO) be used as a direct replacement for RC3216F3923CS (Samsung)?

A: Yes. Both components meet all mandatory matching parameters: 392 kΩ resistance, ±1% tolerance, 0.25W power rating, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. Physical dimensions are identical (0.026" height). No circuit redesign or PCB layout modification is required.

Q: What is the significance of the height variation between substitute parts?

A: Height variations (0.024" to 0.030") remain within the 1206 package specification tolerance of ±0.010". All listed substitutes are compatible with standard PCB assembly equipment, reflow soldering profiles, and automated pick-and-place processes. Height differences do not affect electrical performance or mechanical reliability.

Q: When should AEC-Q200 certified parts be selected?

A: AEC-Q200 certification is required for automotive applications subject to automotive industry reliability standards. Select RMCF1206FT392K, CRCW1206392KFKEA, KTR18EZPF3923, or ERJ-8ENF3923V when designs are destined for automotive end-use or when customer specifications mandate automotive-grade component qualification. Non-automotive industrial applications do not require AEC-Q200 certification.

Q: Is ERJ-8ENF3923V (Panasonic) suitable for new product designs?

A: No. ERJ-8ENF3923V carries "Not For New Designs" product status. This component is restricted to replacement applications in existing systems or legacy product support. For new designs, select from Active-status alternatives: RC1206FR-07392KL, CR1206-FX-3923ELF, RMCF1206FT392K, CRCW1206392KFKEA, or KTR18EZPF3923.

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

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) format, suitable for automated assembly processes and bulk component procurement. Packaging format is consistent across all alternatives.

Q: What inventory considerations apply when selecting substitutes?

A: RC1206FR-07392KL (YAGEO) offers the highest inventory availability (258,248 pcs), providing optimal supply chain continuity. CR1206-FX-3923ELF (Bourns) provides 45,724 pcs. Other alternatives range from 6,068 to 44,395 pcs. Inventory levels should be evaluated against project lead times and supply chain risk tolerance.

Q: Can substitute parts be mixed within a single PCB assembly?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixed sourcing from multiple manufacturers within a single PCB is permissible from a technical standpoint. However, manufacturing process controls and traceability documentation may require component segregation by manufacturer for quality assurance purposes. Consult internal procurement and quality procedures.

Q: What compliance certifications apply to all substitute parts?

A: All listed parts maintain ROHS3 compliance, REACH Unaffected status, EAR99 export classification, and HTSUS code 8533.21.0030. MSL 1 (Unlimited) moisture sensitivity applies universally, eliminating special handling or storage requirements. These certifications are consistent across all alternatives and the primary part.
