MC22FF501F-F Equivalent & Substitute Parts

Part Overview

The MC22FF501F-F is a 500 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 1 kV operation in a 2220 (5750 Metric) surface mount package. This component is classified as Active and is ROHS3 compliant. Mica capacitors in this specification are utilized in RF applications requiring high Q factor and low loss characteristics across the operating temperature range of -55°C to 125°C. Substitute parts are identified when equivalent electrical performance can be maintained within the allowed parameter tolerances for the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MC22FF501F-F is permissible when the following conditions are met:

Mandatory Matching Parameters:

• Capacitance value: 500 pF (exact match required)
• Voltage rating: 1 kV (minimum; higher ratings acceptable)
• Dielectric material: Mica (required for RF performance characteristics)
• Package / Case: 2220 (5750 Metric) (required for PCB footprint compatibility)
• Mounting type: Surface Mount (required for assembly compatibility)
• Operating temperature range: -55°C to 125°C (minimum; wider ranges acceptable)

Allowable Variation Parameters:

• Tolerance: ±1% to ±5% (wider tolerances acceptable when circuit design permits)
• Manufacturer: Cornell Dubilier Electronics (CDE) or equivalent qualified manufacturer
• RoHS and regulatory compliance: ROHS3 compliant status required

The MC22FF501J-F qualifies as a substitute based on these criteria, with the primary difference being tolerance specification (±5% versus ±1%).

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MC22FF501F-F): Select the MC22FF501F-F when circuit design requires the tighter ±1% tolerance specification. This part is Active status with full ROHS3 compliance and REACH unaffected designation. The ±1% tolerance provides superior capacitance accuracy for precision RF applications.

Substitute Part Selection (MC22FF501J-F): The MC22FF501J-F is suitable for applications where the ±5% tolerance is acceptable within circuit performance margins. Both parts share identical electrical ratings, package dimensions, and regulatory compliance status. The substitute part is also Active status, ROHS3 compliant, and REACH unaffected. Selection between these parts depends solely on tolerance requirements and circuit design specifications.

Regulatory and Compliance Considerations: Both parts meet ROHS3 compliance requirements and are REACH unaffected. MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions for either part. Both parts carry ECCN classification EAR99 and HTSUS code 8532.29.0020.

Frequently Asked Questions (FAQ)

Q: Can MC22FF501J-F replace MC22FF501F-F in all applications?

A: The MC22FF501J-F can replace the MC22FF501F-F when the circuit design tolerates the ±5% tolerance specification. Both parts are electrically and mechanically identical except for tolerance. Verify that your circuit design margin accommodates the wider tolerance before substitution.

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

A: The primary difference is capacitance tolerance. MC22FF501F-F specifies ±1% tolerance, while MC22FF501J-F specifies ±5% tolerance. All other electrical parameters, physical dimensions, and regulatory compliance are identical.

Q: Are the physical dimensions identical?

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 are interchangeable.

Q: Do both parts meet RoHS compliance?

A: Yes. Both MC22FF501F-F and MC22FF501J-F are ROHS3 compliant and REACH unaffected. Both carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What is the voltage rating for both parts?

A: Both parts are rated for 1 kV operation. This rating applies to both the main part and substitute part.

Q: Are both parts currently available?

A: Both parts carry Active product status. MC22FF501F-F has 706 pieces in stock; MC22FF501J-F has 1096 pieces in stock.

Q: Can I use a higher voltage rated part as a substitute?

A: Substitution with higher voltage ratings is permissible from an electrical standpoint, provided all other parameters (capacitance, package, tolerance requirements) are met. However, no higher voltage alternatives are listed in this substitution group.

Q: What is the operating temperature range?

A: Both parts operate across -55°C to 125°C. This range is identical for MC22FF501F-F and MC22FF501J-F.
