CM05FD271JO3 Equivalent & Substitute Parts

Part Overview

The CM05FD271JO3 is a 270 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE) in the CM05 series. This through-hole radial component is designed for general-purpose applications requiring high voltage stability and precision capacitance values. The part is currently active in production with 709 units in stock.

Substitute parts become necessary when the original CM05FD271JO3 is unavailable, when design requirements mandate RoHS compliance, or when alternative series options from the same manufacturer provide equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM05FD271JO3 is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Capacitance value: 270 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 500 V (exact match required)
• Dielectric material: Mica (exact match required)

Critical Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead spacing: 0.232" / 5.90mm (exact match required)
• Physical dimensions: 0.469" L x 0.209" W / 11.90mm x 5.30mm (exact match required)
• Height seated (max): 0.390" / 9.90mm (exact match required)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C (exact match required)

The substitute parts CD15FD271JO3 and CD15FD271JO3F meet all critical electrical and mechanical parameters. Both are manufactured by Cornell Dubilier Electronics and belong to the CD15 series, which shares identical specifications with the CM05 series for this capacitance value and voltage rating.

Parameter Comparison

Engineering Selection Recommendations

CM05FD271JO3 (Original Part): Use when the original part number is specified in design documentation or when REACH-affected status is acceptable for the application. This part is currently active with adequate inventory availability.

CD15FD271JO3 (Substitute - Standard): Use as a direct electrical and mechanical equivalent when CM05FD271JO3 is unavailable. This part maintains identical electrical specifications and physical dimensions. Note that this part retains RoHS non-compliant and REACH-affected status, matching the original part's compliance profile.

CD15FD271JO3F (Substitute - Compliance-Enhanced): Use when RoHS3 compliance and REACH-unaffected status are required by design or regulatory specifications. This part provides identical electrical performance and mechanical compatibility while offering improved compliance posture. Highest inventory availability (1070 units) supports supply chain continuity.

All three parts are manufactured by Cornell Dubilier Electronics and share the same ECCN (EAR99) and HTSUS (8532.29.0020) classifications.

Frequently Asked Questions (FAQ)

Q: Can CD15FD271JO3 and CD15FD271JO3F be used interchangeably with CM05FD271JO3?

A: Yes, both CD15 series parts are direct substitutes. All three parts have identical capacitance (270 pF), tolerance (±5%), voltage rating (500 V), dielectric material (Mica), operating temperature range (-55°C to 125°C), and physical dimensions. They are pin-compatible and functionally equivalent for circuit applications.

Q: What is the difference between CD15FD271JO3 and CD15FD271JO3F?

A: The primary differences are compliance certifications. CD15FD271JO3F is ROHS3 compliant and REACH unaffected, while CD15FD271JO3 is RoHS non-compliant and REACH affected. Electrically and mechanically, both parts are identical. Select CD15FD271JO3F when compliance requirements mandate RoHS3 certification or REACH compliance.

Q: Will these parts fit in the same PCB footprint?

A: Yes. All three parts share identical lead spacing (0.232" / 5.90mm), physical dimensions (0.469" L x 0.209" W / 11.90mm x 5.30mm), and maximum seated height (0.390" / 9.90mm). They are mechanically interchangeable on through-hole PCB layouts.

Q: Are there any performance differences between the CM05 and CD15 series for this capacitance value?

A: No. For the 270 pF, 500 V mica capacitor specification, the CM05 and CD15 series provide identical electrical performance, temperature stability, and reliability characteristics.

Q: Which substitute should I select for new designs?

A: For new designs, CD15FD271JO3F is the preferred selection due to ROHS3 compliance and REACH-unaffected status, ensuring alignment with current regulatory requirements and long-term supply chain sustainability.

Q: What is the MSL (Moisture Sensitivity Level) for these parts?

A: CM05FD271JO3 has MSL 1 (Unlimited). CD15FD271JO3 and CD15FD271JO3F have MSL Not Applicable, indicating these mica capacitors do not require moisture-sensitive device handling procedures.
