MC12FD620F-F Equivalent & Substitute Parts

Part Overview

The MC12FD620F-F is a 62 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V operation in a 1210 (3225 Metric) surface mount package. This component is designed for RF applications requiring high Q and low loss characteristics. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits tolerance adjustments within circuit specifications. The primary substitute differs in capacitance tolerance specification while maintaining all other electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MC12FD620F-F is determined by the following criteria:

Critical Parameters (Must Match):

• Capacitance value: 62 pF
• Voltage rating: 500 V
• Dielectric material: Mica
• Package / Case: 1210 (3225 Metric)
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C
• Physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Maximum seated height: 0.079" (2.00mm)

Flexible Parameters (May Vary):

• Capacitance tolerance: ±1% (primary) to ±5% (substitute)
• Packaging format: Tape and reel or Bulk

The MC12FD620J-F qualifies as a direct substitute because it maintains identical capacitance, voltage, dielectric, package, and thermal specifications. The tolerance specification increases from ±1% to ±5%, which represents a relaxation of the precision requirement while remaining within the same component family and electrical classification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MC12FD620F-F): Select the MC12FD620F-F when circuit design specifications require ±1% capacitance tolerance. This part is appropriate for precision RF tuning circuits, impedance matching networks, and applications where tight capacitive value control is essential. The part maintains Active status with full regulatory compliance (RoHS3, REACH Unaffected, EAR99 classification).

Substitute Part Selection (MC12FD620J-F): The MC12FD620J-F is a valid substitute when circuit tolerance budgets accommodate ±5% capacitance variation. This part is suitable for general RF applications, coupling networks, and filtering stages where the relaxed tolerance does not impact circuit performance. Both parts share identical voltage ratings, thermal operating ranges, and physical footprints, ensuring direct PCB compatibility. The substitute maintains equivalent RoHS3 compliance and regulatory status.

Compliance Considerations: Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.29.0020. MSL 1 rating (Unlimited) indicates no moisture sensitivity restrictions for either part during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can MC12FD620J-F replace MC12FD620F-F in all applications?

A: The MC12FD620J-F is a direct substitute only in applications where ±5% capacitance tolerance is acceptable. If the circuit design requires ±1% tolerance for proper operation, the substitute is not appropriate. Review circuit tolerance budgets and tuning range specifications before substitution.

Q: Are the physical dimensions and PCB footprints identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.079" (2.00mm). No PCB layout modifications are required for substitution.

Q: Do both parts have the same voltage rating and temperature range?

A: Yes. Both the MC12FD620F-F and MC12FD620J-F are rated for 500 V operation across the -55°C to 125°C temperature range. Electrical stress and thermal performance are equivalent.

Q: What is the difference between the two parts?

A: The sole difference is capacitance tolerance. The MC12FD620F-F specifies ±1% tolerance, while the MC12FD620J-F specifies ±5% tolerance. All other electrical characteristics, physical dimensions, materials, and compliance certifications are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MC12FD620F-F and MC12FD620J-F are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. No environmental or regulatory restrictions apply to either part.

Q: What packaging formats are available?

A: The MC12FD620F-F is available in standard tape and reel packaging. The MC12FD620J-F is available in Bulk packaging. Confirm packaging requirements with procurement specifications before ordering.
