MC12FD470F-TF Equivalent & Substitute Parts

Part Overview

The MC12FD470F-TF is a 47 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 factor and low loss characteristics. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance can be maintained within the allowed parameter tolerances for this mica capacitor category, specifically when capacitance value, voltage rating, dielectric material, package form factor, and operating temperature range remain constant or compatible.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MC12FD470F-TF is determined by strict equivalence in the following parameters:

• Capacitance Value: Must be 47 pF (no variation permitted)
• Voltage Rating: Must be 500 V or higher
• Dielectric Material: Must be Mica
• Package Form Factor: Must be 1210 (3225 Metric) surface mount
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Mounting Type: Must be Surface Mount

The tolerance specification (±1% vs. ±5%) represents the primary electrical difference among qualified substitutes. A part with relaxed tolerance (±5%) can substitute for the primary part in applications where tighter tolerance control is not required, provided all other parameters remain equivalent.

Engineering Selection Recommendations

MC12FD470F-TF (Primary Selection)

Select this part when circuit design specifications require ±1% capacitance tolerance. The tighter tolerance specification ensures precise frequency tuning and impedance matching in RF applications. Active product status and full RoHS3 compliance support long-term supply chain stability.

MC12FD470J-F (Substitute Selection)

The MC12FD470J-F qualifies as a direct substitute when application requirements permit ±5% capacitance tolerance. This part maintains identical electrical performance in voltage rating, dielectric properties, and thermal operating range. Both parts share equivalent RoHS3 compliance and MSL 1 rating, ensuring identical environmental handling and assembly process compatibility. Selection between these parts depends solely on tolerance requirements specified in the circuit design.

Frequently Asked Questions (FAQ)

Q: Can MC12FD470J-F replace MC12FD470F-TF in all applications?

A: MC12FD470J-F can replace MC12FD470F-TF only in applications where ±5% capacitance tolerance is acceptable. If the circuit design requires ±1% tolerance for frequency stability or impedance control, the substitute part is not suitable.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical length (0.126"), width (0.098"), and maximum seated height (0.079"). PCB layout and assembly tooling are interchangeable.

Q: Do both parts have the same voltage rating?

A: Yes. Both MC12FD470F-TF and MC12FD470J-F are rated for 500 V operation. No derating is required when substituting between these parts.

Q: What is the difference between the part numbers F and J designations?

A: The letter designation indicates tolerance specification. "F" denotes ±1% tolerance; "J" denotes ±5% tolerance. All other electrical and mechanical characteristics remain identical.

Q: Are moisture sensitivity and RoHS compliance the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) rating and ROHS3 compliance. Assembly and storage procedures are identical.

Q: Can these parts be used interchangeably in RF circuits?

A: Both parts provide equivalent RF performance characteristics (High Q, Low Loss). Interchangeability depends on whether the circuit tolerance budget accommodates ±5% capacitance variation. RF tuning circuits requiring precise frequency control should use the ±1% part.
