Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F14R3CS are qualified based on the following criteria:

Primary Substitution Criteria (Exact Match Required):

• Resistance value: 14.3 Ohms
• Tolerance: ±1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Physical dimensions within specified tolerances
• Electrical performance under rated conditions
• Environmental compliance certifications

Substitute parts are grouped into two categories based on power rating compatibility:

Category A - Direct 1/4W (0.25W) Equivalents: Parts with identical power ratings suitable for direct replacement in applications designed for 0.25W dissipation.

Category B - Higher Power Rating (0.75W) Alternatives: Parts with increased power rating capability, suitable for applications requiring enhanced thermal performance or pulse withstanding characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (1/4W Applications):

CRCW120614R3FKEA (Vishay Dale) is the primary equivalent substitute. This part maintains identical electrical specifications and package dimensions while offering AEC-Q200 automotive qualification. Product status is active with 20,713 pieces in stock, providing supply security.

RC1206FR-0714R3L (YAGEO) is an alternative direct equivalent with active product status and 9,097 pieces available. This part matches all critical electrical and mechanical parameters without automotive certification.

For Enhanced Thermal Performance (0.75W Applications):

CRCW120614R3FKEAHP (Vishay Dale) provides increased power rating capability at 0.75W with pulse withstanding characteristics. This part is suitable for applications requiring higher thermal dissipation margins. AEC-Q200 automotive qualification is included. Product status is active with 5,925 pieces in stock.

Parts Not Recommended for New Designs:

ERJ-8ENF14R3V (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. While electrical and mechanical specifications are equivalent, this part should not be selected for new design implementations. Existing designs currently using this part may continue procurement, but migration to active-status alternatives is recommended for long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can CRCW120614R3FKEAHP (0.75W) be used in place of RCS3216F14R3CS (0.25W)?

A: Yes. The CRCW120614R3FKEAHP maintains identical resistance, tolerance, package, and operating temperature specifications. The higher power rating (0.75W vs. 0.25W) provides additional thermal capability and does not create incompatibility. The component will function correctly in circuits designed for 0.25W dissipation. Selection should be based on application thermal requirements and board layout constraints.

Q: What is the difference between the Samsung RCS3216F14R3CS and Vishay CRCW120614R3FKEA?

A: Both parts are electrically and mechanically equivalent with matching 14.3 Ohm resistance, ±1% tolerance, 0.25W power rating, and 1206 package. The primary difference is manufacturer and automotive certification. CRCW120614R3FKEA includes AEC-Q200 automotive qualification, while RCS3216F14R3CS specifies anti-sulfur and moisture-resistant features. Both are ROHS3 compliant with MSL 1 rating.

Q: Why is ERJ-8ENF14R3V marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued active development and promotion of this part number. While existing inventory is available and the part meets all electrical specifications, new design implementations should select from active-status alternatives such as CRCW120614R3FKEA or RC1206FR-0714R3L to ensure long-term supply availability and manufacturer support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the RCS3216F14R3CS compliance status. All parts are also REACH unaffected and classified as EAR99 for export control purposes.

Q: What is the significance of AEC-Q200 automotive qualification?

A: AEC-Q200 is an automotive industry standard qualification for passive components. Parts carrying this certification have undergone rigorous testing for automotive applications including temperature cycling, humidity resistance, and reliability validation. CRCW120614R3FKEA, CRCW120614R3FKEAHP, and ERJ-8ENF14R3V include AEC-Q200 qualification, making them suitable for automotive and high-reliability applications. RCS3216F14R3CS and RC1206FR-0714R3L do not specify this certification.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, within mechanical constraints. All substitute parts use the 1206 (3216 Metric) package with identical footprint requirements. Physical dimensions vary slightly (height-seated maximum ranges from 0.024" to 0.028"), but these variations fall within standard PCB assembly tolerances. Reflow soldering profiles and handling procedures remain consistent across all listed parts.

Q: What inventory levels should be considered for procurement?

A: Current stock levels are: RCS3216F14R3CS (954 pcs), CRCW120614R3FKEA (20,713 pcs), CRCW120614R3FKEAHP (5,925 pcs), ERJ-8ENF14R3V (12,858 pcs), and RC1206FR-0714R3L (9,097 pcs). CRCW120614R3FKEA offers the highest availability. For supply chain continuity, multiple qualified sources should be maintained in design documentation.
