MC22FD511F-F Equivalent & Substitute Parts

Part Overview

The MC22FD511F-F is a 510 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V 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 may be required due to inventory constraints, specific tolerance requirements, or application-driven performance needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the MC22FD511F-F is based on the following criteria:

Fixed Parameters (Non-Negotiable):

• Capacitance: 510 pF
• Voltage Rating: 500 V (minimum)
• Dielectric Material: Mica
• Package / Case: 2220 (5750 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 125°C
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowable Variance):

• Tolerance: ±1% to ±5% (wider tolerance acceptable in non-critical applications)
• Inventory availability and packaging format

The substitute part MC22FD511J-F maintains all fixed parameters while differing only in tolerance specification (±5% versus ±1%). This substitution is valid for applications where the tighter tolerance of the main part is not a circuit requirement.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MC22FD511F-F): Select the MC22FD511F-F when circuit design requires the ±1% tolerance specification. This part is Active status with ROHS3 compliance and MSL 1 rating, suitable for applications demanding precise capacitance values in RF circuits.

Substitute Part Selection (MC22FD511J-F): The MC22FD511J-F is a valid substitute when tolerance relaxation to ±5% is acceptable within circuit performance margins. Both parts share identical electrical ratings (500 V, 510 pF), dielectric material (Mica), package dimensions (2220), and compliance certifications (ROHS3). The substitute part offers higher inventory availability (1333 Pcs versus 714 Pcs) and may be selected for cost optimization or supply chain continuity when tolerance requirements permit.

Compliance Verification: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring regulatory and environmental compatibility across standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MC22FD511J-F replace MC22FD511F-F in all applications?

A: MC22FD511J-F is electrically and mechanically compatible with MC22FD511F-F. The primary difference is tolerance: ±5% versus ±1%. Substitution is valid only when circuit design tolerates the wider tolerance specification. Applications requiring precise tuning or narrow bandwidth filtering may require the ±1% part.

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 0.079" (2.00mm). PCB layout and assembly tooling are interchangeable.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both MC22FD511F-F and MC22FD511J-F are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 125°C. Temperature performance is identical.

Q: Is the voltage rating the same for both parts?

A: Yes. Both parts are rated for 500 V. Voltage specifications are identical.

Q: What is the capacitance tolerance impact on circuit performance?

A: The MC22FD511F-F (±1%) provides tighter capacitance control, resulting in more predictable resonant frequencies and filter characteristics in RF applications. The MC22FD511J-F (±5%) introduces greater capacitance variation, which may affect circuit tuning precision. Selection depends on application bandwidth and frequency stability requirements.

Q: Are there any differences in RF performance characteristics?

A: Both parts are specified with identical RF, High Q, and Low Loss features. Dielectric material (Mica) and electrical ratings are identical, ensuring equivalent RF performance when tolerance requirements are met.
