• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Power rating: 0.25W (1/4W) or higher (0.75W/3/4W acceptable for applications not requiring exact power matching)
• Manufacturer: Different manufacturers permitted
• Packaging format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) acceptable
• Additional features: Automotive AEC-Q200 qualification, pulse withstanding capability, or enhanced moisture resistance permitted as enhancements
• Physical dimensions: Minor variations within 1206 package specification acceptable

Substitute parts are grouped into two categories: Direct Equivalents (matching 0.25W power rating) and Enhanced Alternatives (higher power rating or automotive qualification).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (0.25W Power Rating, Active Status):

1. RC1206FR-073KL (YAGEO) – Recommended as primary substitute. Active product status with highest inventory availability (95,390 pcs). Identical electrical specifications and 1206 package. Moisture-resistant thick film composition matches original specifications.

2. CR1206-FX-3001ELF (Bourns Inc.) – Recommended as secondary substitute. Active product status with substantial inventory (18,913 pcs). Identical electrical specifications and 1206 package. Moisture-resistant composition.

3. AC1206FR-073KL (YAGEO) – Suitable substitute with automotive AEC-Q200 qualification. Active product status with high inventory (18,692 pcs). Enhanced specification for applications requiring automotive-grade components.

Enhanced Alternatives (Higher Power Rating or Automotive Qualification):

4. CRCW12063K00FKEA (Vishay Dale) – Suitable for applications requiring automotive AEC-Q200 qualification. Maintains 0.25W power rating with Active product status and 10,200 pcs inventory.

5. CRCW12063K00FKEAHP (Vishay Dale) – Suitable for applications requiring higher power dissipation capability (0.75W) or pulse withstanding performance. Automotive AEC-Q200 qualified with highest inventory availability (70,414 pcs). Use only when application circuit design permits higher power rating.

6. ERJ-8ENF3001V (Panasonic Electronic Components) – Not recommended for new designs. Product status is "Not For New Designs." Automotive AEC-Q200 qualified but limited inventory (3,353 pcs). Use only for legacy system maintenance or replacement applications.

Selection Criteria:

• For standard applications: RC1206FR-073KL or CR1206-FX-3001ELF
• For automotive applications: AC1206FR-073KL or CRCW12063K00FKEA
• For high-power or pulse-withstanding applications: CRCW12063K00FKEAHP
• Avoid: ERJ-8ENF3001V (not for new designs)

Frequently Asked Questions (FAQ)

Q1: Can I use a 0.75W (3/4W) rated resistor as a substitute for the 0.25W (1/4W) RCS3216F302CS?

A: Yes, the CRCW12063K00FKEAHP (0.75W) is electrically compatible and can be used as a substitute. Higher power rating provides additional thermal margin and is backward compatible with circuits designed for 0.25W components. However, use this substitution only when circuit design permits the higher power rating. No circuit modification is required.

Q2: What is the difference between automotive AEC-Q200 qualified parts and non-qualified parts?

A: Automotive AEC-Q200 qualification indicates the component meets automotive industry reliability and quality standards. Parts such as AC1206FR-073KL, CRCW12063K00FKEA, CRCW12063K00FKEAHP, and ERJ-8ENF3001V carry this certification. Non-qualified parts (RCS3216F302CS, CR1206-FX-3001ELF, RC1206FR-073KL) are suitable for general industrial and consumer applications. Select AEC-Q200 qualified parts for automotive applications.

Q3: Are all substitute parts available in the same packaging formats?

A: No. The RCS3216F302CS is available in standard packaging. Substitute parts are available in different formats: Cut Tape (CT) & Digi-Reel® (AC1206FR-073KL), Tape & Reel (TR) (CR1206-FX-3001ELF, CRCW12063K00FKEA, CRCW12063K00FKEAHP, ERJ-8ENF3001V, RC1206FR-073KL). Verify packaging format compatibility with your procurement and assembly processes before selection.

Q4: Why is ERJ-8ENF3001V marked as "Not For New Designs"?

A: The ERJ-8ENF3001V carries a "Not For New Designs" product status, indicating Panasonic has discontinued active development and recommends against using this part in new circuit designs. This part is suitable only for legacy system maintenance, repair, or replacement of existing installations. For new designs, select from Active status alternatives: RC1206FR-073KL, CR1206-FX-3001ELF, AC1206FR-073KL, CRCW12063K00FKEA, or CRCW12063K00FKEAHP.

Q5: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life and no moisture sensitivity precautions required during storage or handling. All listed substitute parts carry MSL 1 rating, matching the original RCS3216F302CS specification. No special dry-pack storage or baking procedures are necessary before assembly.

Q6: Can I substitute parts with different physical dimensions within the 1206 package?

A: Yes. All listed parts conform to the 1206 (3216 Metric) package specification. Minor dimensional variations exist (length 0.122" to 0.126", height 0.024" to 0.030"), but these fall within standard 1206 package tolerances and are compatible with standard PCB footprints and assembly equipment. No PCB redesign is required.

Q7: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the original RCS3216F302CS. All parts are suitable for applications requiring RoHS compliance.

Q8: What is the temperature coefficient specification and why does it matter?

A: The temperature coefficient of ±100ppm/°C indicates the resistance value changes by approximately 0.01% per degree Celsius across the operating temperature range (-55°C to 155°C). All listed parts share this specification, ensuring consistent performance across temperature extremes. This parameter is critical for precision analog circuits and temperature-sensitive applications.
