Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F4224CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 4.22 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters:

• Package type: 1206 (3216 Metric)
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Number of terminations: 2

Compliance Requirements:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH unaffected status

The CRCW12064M22FKEA from Vishay Dale meets all critical electrical and mechanical parameters. This substitute maintains identical resistance, tolerance, power rating, temperature coefficient, and operating range. Package dimensions and termination count are equivalent. Both parts satisfy ROHS3 compliance and MSL 1 requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RC3216F4224CS and CRCW12064M22FKEA are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability, packaging format, and application-specific certifications.

The RC3216F4224CS features moisture-resistant construction and is supplied in standard packaging. The CRCW12064M22FKEA is supplied in Tape & Reel (TR) format and carries AEC-Q200 automotive qualification. The seated height of the CRCW12064M22FKEA is 0.024" (0.60mm) compared to 0.026" (0.66mm) for the RC3216F4224CS, a difference of 0.002" that may be relevant for space-constrained applications.

Selection should account for supply chain requirements, packaging preferences, and whether automotive-grade qualification is necessary for the application.

Frequently Asked Questions (FAQ)

Q: Can the CRCW12064M22FKEA directly replace the RC3216F4224CS in existing designs?

A: Yes. Both parts share identical electrical specifications (4.22 MOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical dimensions (1206 package, 0.126" x 0.063"). The maximum seated height difference of 0.002" is negligible for standard PCB assembly. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the significance of the AEC-Q200 rating on the CRCW12064M22FKEA?

A: AEC-Q200 is an automotive qualification standard. The CRCW12064M22FKEA meets this specification; the RC3216F4224CS does not list this certification. If automotive-grade components are required, the CRCW12064M22FKEA is the appropriate selection.

Q: Are there packaging differences between these parts?

A: The RC3216F4224CS is supplied in standard packaging. The CRCW12064M22FKEA is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. Both are suitable for pick-and-place equipment.

Q: Do both parts meet moisture sensitivity requirements?

A: Yes. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture bake-out requirement prior to soldering and unlimited shelf life under normal storage conditions.

Q: What compliance certifications apply to both parts?

A: Both the RC3216F4224CS and CRCW12064M22FKEA are ROHS3 compliant and REACH unaffected. Both carry ECCN EAR99 classification and HTSUS code 8533.21.0030.
