Part Overview

The RC3216F3920CS is a 392 Ohm thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This surface mount device delivers 0.25W power dissipation with ±1% tolerance and moisture-resistant construction. The part is currently Active in product status with 786 pieces in stock inventory.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package type, physical dimensions), and environmental ratings (operating temperature range, RoHS compliance, moisture sensitivity level). Substitutes enable design flexibility, supply chain continuity, and alternative sourcing options when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Electrical Specifications: Resistance value (392 Ohms), tolerance (±1%), and power rating (0.25W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package type (1206 / 3216 Metric) and number of terminations (2) are mandatory. Physical dimensions (length, width, height) must be compatible with PCB footprints designed for 1206 packages.

Environmental & Compliance Standards: All substitute parts must maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status. Operating temperature range must encompass or match the original specification.

Composition & Construction: Thick film construction is the standard for this category. Moisture-resistant or automotive-grade features (AEC-Q200) represent enhanced capabilities that do not disqualify substitution but indicate additional qualification.

Substitute parts are classified as Direct Substitutes (functionally and mechanically identical) or Similar Substitutes (matching core parameters with enhanced features such as automotive qualification).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Direct Compatibility):

CR1206-FX-3920ELF (Bourns Inc.) and RC1206FR-07392RL (YAGEO) are direct substitutes with Active product status. Both maintain moisture-resistant construction and identical electrical specifications. CR1206-FX-3920ELF offers higher inventory availability (20,393 pieces). RC1206FR-07392RL provides the largest stock position (231,977 pieces) and represents the most readily available alternative.

Automotive-Qualified Substitutes (Active Status, Enhanced Features):

RMCF1206FT392R (Stackpole Electronics Inc), CRCW1206392RFKEA (Vishay Dale), and KTR18EZPF3920 (Rohm Semiconductor) are Active parts with AEC-Q200 automotive qualification. These parts meet all core electrical and mechanical parameters while providing additional environmental testing and reliability documentation. KTR18EZPF3920 includes high-voltage capability. Selection of automotive-qualified parts is appropriate for applications requiring enhanced qualification documentation or automotive supply chain compliance.

Legacy Substitute (Discontinued for New Designs):

ERJ-8ENF3920V (Panasonic Electronic Components) carries "Not For New Designs" status despite meeting all electrical and mechanical specifications. This part is suitable only for legacy system maintenance or repair applications where design continuity is required. New designs should not incorporate this part number.

Selection Criteria:

For standard industrial applications, select from CR1206-FX-3920ELF or RC1206FR-07392RL based on inventory availability and lead time requirements. For automotive or mission-critical applications, select from RMCF1206FT392R, CRCW1206392RFKEA, or KTR18EZPF3920 based on supplier preference and qualification documentation requirements. Avoid ERJ-8ENF3920V for new designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F3920CS with any of the listed parts without circuit redesign?

A: Yes. All listed Direct and Similar Substitute parts maintain identical electrical specifications (392 Ohms ±1%, 0.25W), operating temperature range (-55°C ~ 155°C), and 1206 package compatibility. No circuit redesign is required. Physical dimensions are within acceptable tolerance for standard 1206 PCB footprints.

Q: What is the difference between Direct Substitutes and Similar Substitutes?

A: Direct Substitutes (CR1206-FX-3920ELF, RC1206FR-07392RL) match the original part's moisture-resistant feature set and Active product status. Similar Substitutes (RMCF1206FT392R, CRCW1206392RFKEA, KTR18EZPF3920) add automotive AEC-Q200 qualification or high-voltage capability. Both categories meet all core electrical and mechanical requirements.

Q: Why is ERJ-8ENF3920V marked "Not For New Designs"?

A: ERJ-8ENF3920V carries this designation from the manufacturer, indicating the part is in legacy status. While it meets all electrical and mechanical specifications, Panasonic has discontinued active development and qualification for new applications. Use this part only for repair or maintenance of existing systems already using this component.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original RC3216F3920CS specification. All parts are also REACH Unaffected and carry MSL Level 1 (Unlimited) moisture sensitivity rating.

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

A: AEC-Q200 is an automotive industry standard qualification for passive components. Parts carrying this rating (RMCF1206FT392R, CRCW1206392RFKEA, KTR18EZPF3920) have undergone additional environmental stress testing and reliability documentation. These parts are suitable for automotive applications or systems requiring enhanced qualification documentation. Non-automotive applications do not require AEC-Q200 qualification.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes. All substitute parts are electrically and mechanically compatible. Mixing different manufacturers on the same board is acceptable from an engineering standpoint. However, supply chain and procurement practices may favor standardizing on a single part number per design to simplify inventory management and qualification documentation.

Q: What is the difference in physical dimensions between substitute parts?

A: All parts use the 1206 (3216 Metric) package with nominal dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm). Height varies slightly: RC3216F3920CS and RC1206FR-07392RL measure 0.026" (0.65mm); CR1206-FX-3920ELF measures 0.030" (0.75mm); ERJ-8ENF3920V and RMCF1206FT392R measure 0.028" (0.70mm); CRCW1206392RFKEA measures 0.024" (0.60mm); KTR18EZPF3920 measures 0.026" (0.65mm). These height variations are within standard 1206 package tolerance and do not affect PCB assembly compatibility.

Q: Which substitute part offers the best inventory availability?

A: RC1206FR-07392RL (YAGEO) provides the largest stock position with 231,977 pieces available. CR1206-FX-3920ELF (Bourns Inc.) offers 20,393 pieces. For immediate availability, RC1206FR-07392RL is the preferred choice.
