Parameter Comparison

Engineering Selection Recommendations

All three part numbers—CM05FD271GO3, CD15FD271GO3, and CD15FD271GO3F—are electrically and mechanically equivalent for applications requiring a 270 pF, 500 V mica capacitor in radial through-hole configuration.

Selection Criteria Based on Compliance Requirements:

CM05FD271GO3: Select this part when RoHS non-compliance and REACH-affected status are acceptable for the application. This part is suitable for legacy designs or applications without regulatory compliance constraints.

CD15FD271GO3: Select this part as a direct functional equivalent when inventory availability is a priority. This part maintains the same compliance profile as CM05FD271GO3 (RoHS non-compliant, REACH Affected) while offering higher stock availability (1424 pcs vs. 849 pcs).

CD15FD271GO3F: Select this part when ROHS3 compliance and REACH unaffected status are required. This part is suitable for applications subject to environmental regulations, RoHS directives, or customer specifications mandating compliance certifications. Stock availability is 1140 pcs.

All parts share identical electrical performance, temperature stability, and mechanical fit characteristics. Selection between substitute parts depends solely on regulatory compliance requirements and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can CD15FD271GO3 and CD15FD271GO3F be used interchangeably with CM05FD271GO3?

A: Yes, both CD15 series parts are electrically and mechanically equivalent to CM05FD271GO3. All three parts have identical capacitance (270 pF), voltage rating (500 V), tolerance (±2%), operating temperature range (-55°C to 125°C), and physical dimensions. The differences are limited to compliance certifications and series designation.

Q: What is the difference between CD15FD271GO3 and CD15FD271GO3F?

A: Both parts are electrically and mechanically identical. The primary difference is compliance status: CD15FD271GO3 is RoHS non-compliant and REACH Affected, while CD15FD271GO3F is ROHS3 Compliant and REACH Unaffected. Select CD15FD271GO3F for applications requiring environmental compliance certifications.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts have identical dimensions: 0.469" L x 0.209" W (11.90 mm x 5.30 mm), with maximum seated height of 0.390" (9.90 mm), and lead spacing of 0.232" (5.90 mm). They are direct mechanical substitutes for through-hole PCB mounting.

Q: What is the lead spacing for these radial mica capacitors?

A: The lead spacing is 0.232" (5.90 mm) for all three parts. This dimension is critical for PCB footprint compatibility and must match the design layout.

Q: Can these 270 pF mica capacitors be used in high-frequency applications?

A: Mica dielectric capacitors are suitable for high-frequency applications due to their low loss characteristics and stable capacitance across frequency ranges. However, specific frequency performance depends on circuit design requirements and is not specified in the provided parameters.

Q: What is the tolerance specification for these capacitors?

A: All three parts have a tolerance of ±2%, meaning the actual capacitance will be within 264.6 pF to 275.4 pF of the nominal 270 pF value.

Q: Are these parts suitable for high-voltage applications?

A: Yes. All three parts are rated for 500 V operation and are designed for general-purpose high-voltage applications. The mica dielectric provides excellent voltage stability and low leakage current.
