Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F7321CS are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical resistance value (7.32 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C).

Package Compatibility: All substitutes use the 1206 (3216 Metric) surface-mount package with 2 terminations, ensuring mechanical and electrical compatibility with existing PCB layouts.

Compliance Alignment: All parts are RoHS3 compliant and carry MSL Level 1 rating, meeting environmental and moisture handling requirements.

Composition: All substitutes employ thick film construction, maintaining performance characteristics and reliability profiles equivalent to the original part.

The four qualified substitutes differ in manufacturer, specific features (anti-sulfur vs. automotive AEC-Q200 qualification), and product status, allowing selection based on supply availability and application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

For Active Production: CR1206-FX-7321ELF (Bourns), CRCW12067K32FKEA (Vishay Dale), and RC1206FR-077K32L (YAGEO) are all Active status parts suitable for new designs. These three options provide equivalent electrical performance with full compliance certifications.

For Automotive Applications: CRCW12067K32FKEA and ERJ-8ENF7321V both carry AEC-Q200 automotive qualification. CRCW12067K32FKEA is recommended for new automotive designs due to Active product status.

For General Industrial Applications: CR1206-FX-7321ELF and RC1206FR-077K32L offer moisture-resistant construction suitable for standard industrial environments with Active product status and full compliance.

Avoid for New Designs: ERJ-8ENF7321V carries "Not For New Designs" status and should only be used for legacy system maintenance or repair applications.

Supply Considerations: RC1206FR-077K32L (YAGEO) offers the highest inventory availability (33,697 pcs), followed by CR1206-FX-7321ELF (Bourns, 25,497 pcs) and CRCW12067K32FKEA (Vishay Dale, 10,464 pcs).

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F7321CS with any of these parts without circuit redesign?

A: Yes. All four substitute parts maintain identical electrical specifications (7.32 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and use the same 1206 package, ensuring direct functional equivalence and PCB compatibility without circuit modifications.

Q: What is the difference between the anti-sulfur feature on the Samsung part and the standard moisture-resistant versions?

A: The RCS3216F7321CS includes anti-sulfur protection in addition to moisture resistance. The Bourns CR1206-FX-7321ELF and YAGEO RC1206FR-077K32L provide moisture resistance only. For applications requiring anti-sulfur protection, the original Samsung part or automotive-qualified alternatives (Vishay Dale CRCW12067K32FKEA or Panasonic ERJ-8ENF7321V) should be evaluated based on specific environmental requirements.

Q: Are the automotive AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification represents a higher reliability standard and is fully compatible with non-automotive applications. CRCW12067K32FKEA (Vishay Dale) and ERJ-8ENF7321V (Panasonic) can be used in any application requiring the 7.32 kΩ ±1% 0.25W specification.

Q: Why is ERJ-8ENF7321V marked "Not For New Designs"?

A: This designation indicates the part is in mature/legacy status. While electrically equivalent and currently in stock, Panasonic recommends using alternative sources for new product development. Use ERJ-8ENF7321V only for sustaining production or repair of existing systems.

Q: Do all substitutes have the same physical dimensions?

A: All parts use the 1206 (3216 Metric) package. Minor variations exist in maximum seated height: Samsung RCS3216F7321CS (0.66mm), Bourns CR1206-FX-7321ELF (0.75mm), Vishay Dale CRCW12067K32FKEA (0.60mm), YAGEO RC1206FR-077K32L (0.65mm), and Panasonic ERJ-8ENF7321V (0.70mm). These variations are within standard PCB assembly tolerances and do not affect functionality or compatibility.

Q: Are all parts RoHS3 compliant?

A: Yes. All five parts (original and four substitutes) are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for global markets.
