MC22FF151D-F Mica Capacitor: Equivalent & Substitute Parts

Part Overview

The MC22FF151D-F is a 150 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 with full RoHS3 compliance and MSL Level 1 rating. 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, procurement lead times, or application-specific tolerance requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution logic for the MC22FF151D-F is based on strict electrical and mechanical parameter matching within the mica capacitor category. The primary substitute identified is the MC22FF151J-F, which shares identical specifications in the following critical parameters:

Matching Parameters (Substitution Basis):

• Capacitance: 150 pF (exact match)
• Voltage Rating: 1 kV (exact match)
• Dielectric Material: Mica (exact match)
• Package / Case: 2220 (5750 Metric) (exact match)
• Mounting Type: Surface Mount (exact match)
• Operating Temperature Range: -55°C ~ 125°C (exact match)
• Features: RF, High Q, Low Loss (exact match)
• RoHS Status: ROHS3 Compliant (exact match)
• MSL Rating: 1 (Unlimited) (exact match)
• Physical Dimensions: 0.224" L x 0.197" W / 5.70mm x 5.00mm (exact match)
• Height - Seated (Max): 0.157" (4.00mm) (exact match)

Differing Parameter:

• Tolerance: MC22FF151D-F operates at ±0.5% precision, while MC22FF151J-F operates at ±5% tolerance

The tolerance difference represents the only electrical variance. The MC22FF151J-F is suitable as a substitute in applications where the ±5% tolerance specification is acceptable within circuit design margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: MC22FF151D-F

Select the MC22FF151D-F when circuit design specifications require ±0.5% capacitance tolerance. This precision grade is appropriate for RF applications with tight tuning requirements, impedance matching networks, or frequency-critical filter designs. Both parts maintain Active product status with full RoHS3 compliance and identical thermal performance across -55°C to 125°C operating range.

Substitute Part: MC22FF151J-F

The MC22FF151J-F is electrically and mechanically compatible as a substitute when application circuit design tolerates ±5% capacitance variation. This wider tolerance specification does not affect PCB assembly compatibility, thermal performance, voltage rating, or regulatory compliance. Both parts are manufactured by Cornell Dubilier Electronics within the MC series and share identical package geometry, mounting characteristics, and RF performance features.

Compliance and Certification:

Both parts maintain identical regulatory status: ROHS3 Compliant, REACH Unaffected, MSL Level 1 (Unlimited moisture sensitivity), and EAR99 export classification. No compliance trade-offs exist between the main part and substitute.

Frequently Asked Questions (FAQ)

Q: Can MC22FF151J-F replace MC22FF151D-F in all applications?
