MC22FF241D-F Equivalent & Substitute Parts

Part Overview

The MC22FF241D-F is a 240 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 product status and is RoHS3 compliant. Mica capacitors of 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 may be required due to inventory constraints, procurement lead times, or specific tolerance requirements for circuit design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the MC22FF241D-F is based on the following criteria:

Fixed Parameters (Non-Negotiable):

• Capacitance: 240 pF (exact match required)
• Voltage Rating: 1 kV (minimum requirement)
• Dielectric Material: Mica (electrical performance requirement)
• Package / Case: 2220 (5750 Metric) (PCB compatibility requirement)
• Mounting Type: Surface Mount (assembly process requirement)
• Operating Temperature Range: -55°C to 125°C (environmental requirement)

Variable Parameters (Allowed Substitution Range):

• Tolerance: ±0.5% (main part) to ±5% (substitute part) — wider tolerance acceptable for non-precision applications
• Packaging Format: Tape/Reel (main part) to Bulk (substitute part) — does not affect component performance

The MC22FF241J-F qualifies as a direct substitute because it maintains all fixed parameters while permitting a relaxed tolerance specification. This substitution is valid for applications where ±5% capacitance tolerance is acceptable within circuit design margins.

Parameter Comparison

Engineering Selection Recommendations

MC22FF241D-F Selection Criteria:

• Select this part when circuit design requires ±0.5% capacitance tolerance for precision RF tuning, impedance matching, or frequency-critical applications
• Preferred for applications with strict component specification requirements
• Active product status ensures continued availability and manufacturing support

MC22FF241J-F Selection Criteria:

• Select this part when circuit design tolerates ±5% capacitance variation without performance degradation
• Suitable for general-purpose RF applications where tolerance stack-up analysis permits wider component variation
• Active product status ensures continued availability and manufacturing support
• Higher inventory availability (1335 Pcs vs. 1094 Pcs) may reduce procurement lead time

Compliance Considerations: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited), ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can MC22FF241J-F replace MC22FF241D-F in any application?

A: MC22FF241J-F is a valid substitute only when the circuit design accommodates ±5% capacitance tolerance. Applications requiring ±0.5% tolerance precision must use MC22FF241D-F. Verify tolerance stack-up analysis in your circuit design documentation before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2220 (5750 Metric) package with identical dimensions: 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 have the same voltage rating?

A: Yes. Both MC22FF241D-F and MC22FF241J-F are rated for 1 kV operation. Voltage rating is not a differentiating factor between these parts.

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

A: The primary difference is capacitance tolerance. MC22FF241D-F specifies ±0.5% tolerance, while MC22FF241J-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 across the -55°C to 125°C operating temperature range, making them suitable for RF circuit applications.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Can I use these parts interchangeably in production?

A: Interchangeability depends on circuit tolerance requirements. If your design specification permits ±5% capacitance tolerance, both parts are production-interchangeable. If your design requires ±0.5% tolerance, only MC22FF241D-F is acceptable.
