Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F1912CS are qualified based on the following critical parameters:

Electrical Specifications: Resistance value of 19.1 kOhms, tolerance of ±1%, and power rating of 0.25W (1/4W) must match exactly. Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C define thermal performance boundaries.

Mechanical Compatibility: Package type 1206 (3216 Metric) with two terminations ensures PCB footprint compatibility. Physical dimensions (length, width, and seated height) must accommodate the same land pattern and assembly process.

Compliance & Environmental: RoHS3 compliance, MSL Level 1 (Unlimited moisture sensitivity), and REACH Unaffected status are mandatory for regulatory equivalence. ECCN EAR99 and HTSUS 8533.21.0030 classifications remain consistent across all qualified substitutes.

Composition & Features: Thick film construction with moisture-resistant properties maintains performance characteristics. Automotive AEC-Q200 qualification is an additional feature available in certain substitute options but is not required for basic equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RC1206FR-0719K1L (YAGEO) is the recommended direct substitute. This part maintains Active product status, matches all electrical and mechanical specifications, and provides the highest inventory availability (22,700 pieces). Both Samsung RC3216F1912CS and YAGEO RC1206FR-0719K1L are current production components suitable for new designs.

Alternative with Automotive Qualification: CRCW120619K1FKEA (Vishay Dale) is suitable for applications requiring AEC-Q200 automotive-grade certification. This part is Active in production status and provides enhanced reliability documentation for automotive environments. Inventory availability is 14,832 pieces.

Legacy Applications Only: ERJ-8ENF1912V (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. This part is electrically and mechanically equivalent but should be used only for replacement or repair of existing assemblies. Panasonic has transitioned this series to obsolescence. Inventory availability is 54,918 pieces.

Compliance Verification: All four parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status. Selection between Active and Not For New Designs parts depends on application lifecycle requirements and supply chain strategy.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-0719K1L replace RC3216F1912CS directly on the PCB?

A: Yes. Both parts share identical 1206 (3216 Metric) package dimensions, two-terminal configuration, and electrical specifications (19.1 kOhms ±1%, 0.25W, ±100ppm/°C). Physical dimensions are within acceptable tolerance for the same PCB footprint. No circuit redesign is required.

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

A: The RC3216F1912CS (Samsung) and RC1206FR-0719K1L (YAGEO) are functionally equivalent. Differences exist only in manufacturer series designation (RC vs. RC_L), packaging format (not specified vs. Tape & Reel), and minor dimensional variations (3.20mm vs. 3.10mm length; 0.66mm vs. 0.65mm height). These variations are within standard PCB assembly tolerances.

Q: Why is ERJ-8ENF1912V marked "Not For New Designs"?

A: Panasonic has discontinued active development of the ERJ-8EN series. This designation indicates the manufacturer will not guarantee long-term availability or support for new product development. The part remains electrically and mechanically compatible but should be reserved for legacy system maintenance only.

Q: Are the Vishay Dale and Panasonic parts suitable for automotive applications?

A: CRCW120619K1FKEA (Vishay Dale) carries AEC-Q200 automotive qualification. ERJ-8ENF1912V (Panasonic) also carries AEC-Q200 qualification but is marked Not For New Designs. The Samsung RC3216F1912CS and YAGEO RC1206FR-0719K1L do not specify automotive qualification. Selection depends on whether the application requires formal automotive-grade certification.

Q: What is the significance of MSL Level 1 rating?

A: MSL Level 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All four substitute parts share this rating, eliminating moisture sensitivity as a selection criterion.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All four parts operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient. Thermal performance is equivalent across all substitutes within this operating window.

Q: What packaging formats are available?

A: RC1206FR-0719K1L, CRCW120619K1FKEA, and ERJ-8ENF1912V are supplied in Tape & Reel (TR) format for automated assembly. The RC3216F1912CS packaging format is not specified in the provided data. Confirm packaging requirements with your procurement process before finalizing part selection.
