Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F5491CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (5.49 kOhms), tolerance (±1%), and power rating (0.25W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Parameters: Package type (1206 / 3216 Metric) and number of terminations (2) are mandatory for physical compatibility. Dimensional variations within supplier specifications are acceptable provided they do not exceed standard 1206 envelope limits.

Environmental & Compliance Parameters: RoHS3 compliance, MSL 1 rating, and thick film composition are required. Moisture resistance is a specified feature of the main part and substitute candidates.

Product Status Consideration: Active status is preferred for new designs; parts with "Not For New Designs" status are identified but noted for legacy applications only.

The three substitute parts listed below meet all electrical and mechanical equivalence criteria while maintaining full environmental compliance.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-075K49L (YAGEO): This part is a direct equivalent with Active product status, making it suitable for new designs. It maintains identical electrical specifications and environmental compliance. The YAGEO RC_L series offers high inventory availability (6066 pcs) and standard Tape & Reel packaging for automated assembly processes.

CRCW12065K49FKEA (Vishay Dale): This substitute includes AEC-Q200 automotive qualification, providing enhanced reliability for applications requiring automotive-grade components. Product status is Active. The CRCW series is widely used in industrial and automotive applications with robust supply chain support (14321 pcs in stock).

ERJ-8ENF5491V (Panasonic): This part carries AEC-Q200 automotive qualification and maintains full electrical and mechanical equivalence. However, product status is listed as "Not For New Designs," restricting its use to legacy system maintenance and repair applications only. Highest inventory availability (61791 pcs) indicates established market presence for existing designs.

For new circuit designs, RC1206FR-075K49L or CRCW12065K49FKEA are recommended. For automotive applications requiring AEC-Q200 qualification, CRCW12065K49FKEA is the preferred Active-status option. ERJ-8ENF5491V is suitable only for replacement in existing systems using this component.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-075K49L replace RC3216F5491CS in all applications?

A: Yes. Both parts share identical resistance (5.49 kOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Dimensional variations (3.10mm vs 3.20mm length) remain within standard 1206 envelope specifications and do not affect circuit board layout or electrical performance.

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

A: The RC3216F5491CS (Samsung) and RC1206FR-075K49L (YAGEO) are electrically and mechanically equivalent. Primary differences are manufacturer, series designation (RC vs RC_L), and packaging format (bulk vs Tape & Reel). Both are Active products with identical compliance certifications.

Q: Why is ERJ-8ENF5491V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development of this part number for new applications. While the part remains functionally equivalent and available in high quantities, it is reserved for legacy system support and repair. New designs should specify RC1206FR-075K49L or CRCW12065K49FKEA.

Q: Are the automotive-qualified parts (CRCW12065K49FKEA and ERJ-8ENF5491V) required for non-automotive applications?

A: No. AEC-Q200 qualification is an additional feature that exceeds standard industrial requirements. For non-automotive applications, any of the three substitutes meets functional requirements. AEC-Q200 parts are specified only when automotive reliability standards are mandated by application requirements.

Q: Does packaging format (bulk vs Tape & Reel) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Bulk and Tape & Reel formats contain identical components with identical electrical specifications. Selection depends on manufacturing process requirements (manual vs automated assembly).

Q: Are all substitutes RoHS3 compliant?

A: Yes. All four parts (main part and three substitutes) carry ROHS3 Compliant status and are REACH Unaffected, meeting current environmental and regulatory requirements for commercial and industrial applications.
