Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MC22FF221D-F is determined by strict alignment of electrical and mechanical parameters. The primary substitution criterion is tolerance relaxation from ±0.5% to ±5%, which is permissible only in applications where circuit design tolerances accommodate the wider capacitance variance. All substitute parts must maintain identical capacitance value (220 pF), voltage rating (1 kV), dielectric material (Mica), package configuration (2220), mounting type (Surface Mount), and operating temperature range (-55°C ~ 125°C). The RF, High Q, and Low Loss characteristics must be preserved across all equivalent parts to ensure performance in RF circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The MC22FF221J-F serves as a direct substitute for the MC22FF221D-F when circuit design specifications permit tolerance relaxation from ±0.5% to ±5%. Both parts are Active products manufactured by Cornell Dubilier Electronics and maintain identical electrical performance characteristics for RF applications. Both components are ROHS3 Compliant and REACH Unaffected, ensuring regulatory compliance across industrial and commercial applications. The substitute part offers higher inventory availability (1979 units versus 1155 units), providing supply chain flexibility. Selection between these parts depends solely on tolerance requirements specified in the circuit design. Where ±0.5% tolerance is mandatory, the MC22FF221D-F must be used. Where ±5% tolerance is acceptable, the MC22FF221J-F provides equivalent functionality with improved availability.

Frequently Asked Questions (FAQ)

Q: Can MC22FF221J-F replace MC22FF221D-F in all applications?

A: The MC22FF221J-F can replace the MC22FF221D-F only in applications where the circuit design tolerates ±5% capacitance variance. If the design requires ±0.5% tolerance, substitution is not permissible.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2220 (5750 Metric) package with identical dimensions of 0.224" L x 0.197" W (5.70mm x 5.00mm) and maximum seated height of 0.157" (4.00mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both MC22FF221D-F and MC22FF221J-F are ROHS3 Compliant, REACH Unaffected, and rated for -55°C ~ 125°C operating temperature. Moisture Sensitivity Level is 1 (Unlimited) for both parts.

Q: What is the primary difference between these two parts?

A: The sole electrical difference is capacitance tolerance: MC22FF221D-F specifies ±0.5% tolerance, while MC22FF221J-F specifies ±5% tolerance. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for RF applications?

A: Yes. Both parts feature RF, High Q, and Low Loss characteristics and are designed for RF circuit applications requiring mica dielectric capacitors.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For designs requiring ±0.5% tolerance, specify MC22FF221D-F. For designs where ±5% tolerance is acceptable, either part is suitable; MC22FF221J-F offers higher inventory availability.
