Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F22R1CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 22.1 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these mandatory criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in specific features (anti-sulfur vs. moisture-resistant vs. automotive AEC-Q200 ratings) do not disqualify substitution, as these represent design enhancements rather than functional limitations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The following parts are recommended for new designs and production applications:

• CR1206-FX-22R1ELF (Bourns Inc.): Active status with 45,326 units in stock. Moisture-resistant thick film construction. Suitable for general-purpose applications.

• CRCW120622R1FKEA (Vishay Dale): Active status with 17,418 units in stock. Automotive AEC-Q200 rated. Recommended for automotive and high-reliability applications requiring enhanced qualification standards.

• RC1206FR-0722R1L (YAGEO): Active status with highest inventory availability at 191,439 units. Moisture-resistant thick film construction. Suitable for high-volume production requirements.

• RMCF1206FT22R1 (Stackpole Electronics Inc): Active status with 29,889 units in stock. Automotive AEC-Q200 rated. Recommended for automotive and high-reliability applications.

Secondary Substitute (Legacy Status):

• ERJ-8ENF22R1V (Panasonic Electronic Components): Marked "Not For New Designs." This part meets all electrical and mechanical specifications but should not be selected for new product development. Existing inventory of 42,986 units may be used for legacy system maintenance or repair applications only.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical electrical performance within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q1: Can I substitute RCS3216F22R1CS with any of the listed parts without circuit board modification?

A: Yes. All listed substitute parts share identical electrical specifications (22.1 Ω ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and 1206 package format. Direct substitution on existing PCB layouts is possible without design changes.

Q2: What is the difference between the anti-sulfur feature of RCS3216F22R1CS and the moisture-resistant feature of CR1206-FX-22R1ELF?

A: Anti-sulfur and moisture-resistant are distinct protective features. Anti-sulfur protection specifically addresses sulfur contamination in industrial environments, while moisture-resistant protection addresses humidity exposure. Both provide environmental protection but target different degradation mechanisms. Selection depends on the specific operating environment.

Q3: Why is ERJ-8ENF22R1V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and support for this part. While the part meets all electrical and mechanical specifications and remains in stock, it should not be selected for new product designs. Use this part only for maintenance, repair, or legacy system support.

Q4: Are the automotive AEC-Q200 rated parts (CRCW120622R1FKEA and RMCF1206FT22R1) required for non-automotive applications?

A: No. AEC-Q200 certification indicates enhanced qualification testing and reliability standards specific to automotive environments. For non-automotive applications, any active substitute part meeting the electrical and mechanical specifications is acceptable. AEC-Q200 parts may be used in non-automotive applications without penalty, but the certification is not required.

Q5: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL Level 1 indicates unlimited shelf life without moisture baking requirements. All listed parts, including the main part, have MSL 1 rating, meaning they can be stored indefinitely without special humidity control or pre-reflow baking procedures.

Q6: Which substitute part offers the best inventory availability?

A: RC1206FR-0722R1L (YAGEO) offers the highest inventory availability with 191,439 units in stock, making it the optimal choice for high-volume production requirements or immediate delivery needs.

Q7: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including the main part RCS3216F22R1CS, are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
