D105F271JO3 Equivalent & Substitute Parts Reference

Part Overview

The D105F271JO3 is a 270 pF mica capacitor rated for 500 V operation in a radial through-hole package, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as a general-purpose mica capacitor suitable for applications requiring high voltage stability and low loss characteristics. The part maintains active product status with 833 units currently in stock.

Identification of equivalent and substitute parts becomes necessary when the primary part number experiences supply constraints, when design revisions require compliance updates, or when inventory optimization requires selection among functionally identical alternatives from the same manufacturer series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D105F271JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-negotiable):

• Capacitance value: 270 pF
• Tolerance: ±5%
• Voltage rating: 500 V
• Dielectric material: Mica

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.142" (3.60 mm)
• Physical dimensions: 0.390" L × 0.220" W (9.90 mm × 5.60 mm)
• Maximum seated height: 0.382" (9.70 mm)

Operational Parameters (Non-negotiable):

• Operating temperature range: -55°C to 125°C

The substitute part D105F271JO3F meets all electrical, mechanical, and operational requirements for direct substitution. Both parts are manufactured by Cornell Dubilier Electronics within the D10 series and share identical functional specifications.

Engineering Selection Recommendations

D105F271JO3F as Primary Selection:

The D105F271JO3F is the preferred substitute when regulatory compliance is a design requirement. This part number variant achieves ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to European Union environmental directives and international supply chain restrictions. The higher current inventory level (1125 units) provides improved supply chain reliability.

D105F271JO3 for Legacy Applications:

The original D105F271JO3 remains appropriate for applications where RoHS compliance is not mandated and REACH-affected status does not present regulatory barriers. This part number maintains active status and adequate inventory availability (833 units).

Compliance Considerations:

Selection between these two part numbers should be driven by end-application regulatory requirements and supply chain constraints rather than electrical performance, as both parts are electrically and mechanically identical. Organizations implementing RoHS3 compliance programs should transition to D105F271JO3F for new designs and procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can D105F271JO3F be used as a direct replacement for D105F271JO3 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The D105F271JO3F can be substituted without circuit redesign or PCB layout modification. The only differences are regulatory compliance certifications and inventory levels.

Q: What is the difference between the RoHS status of these two parts?

A: D105F271JO3 is RoHS non-compliant, while D105F271JO3F is ROHS3 compliant. ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive 3 requirements. Selection depends on whether your application or supply chain requires RoHS certification.

Q: Are the physical dimensions and PCB footprints identical?

A: Yes. Both parts share identical dimensions (0.390" L × 0.220" W, 9.90 mm × 5.60 mm), lead spacing (0.142" / 3.60 mm), and maximum seated height (0.382" / 9.70 mm). No PCB layout changes are required when substituting between these part numbers.

Q: What does REACH Unaffected status mean for D105F271JO3F?

A: REACH Unaffected status indicates the part does not contain substances of very high concern (SVHC) listed under the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. D105F271JO3F presents fewer regulatory documentation requirements in international supply chains.

Q: Can I use either part in high-temperature applications?

A: Both parts operate across the identical temperature range of -55°C to 125°C. Selection between them should not be based on thermal performance, as they are thermally equivalent.

Q: Which part should I specify for new product designs?

A: Specify D105F271JO3F for new designs unless legacy compatibility with existing inventory or non-compliant component specifications is required. The ROHS3 compliance and REACH unaffected status of D105F271JO3F align with current regulatory trends and supply chain best practices.
