CD5EC430JO3F Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CD5EC430JO3F is a 43 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD5 series. This through-hole radial capacitor operates at 300 V with ±5% tolerance and is designed for general-purpose applications requiring stable capacitance and low moisture sensitivity. The part maintains Active product status with full RoHS3 compliance and REACH unaffected classification. Substitute parts are identified when inventory constraints, supply chain disruptions, or manufacturing discontinuation necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD5EC430JO3F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 43 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 300 V (exact match required)
• Dielectric material: Mica (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.118" / 3.00 mm (exact match required)
• Physical dimensions: 0.272" L x 0.142" W / 6.90 mm x 3.60 mm (exact match required)
• Maximum seated height: 0.209" / 5.30 mm (exact match required)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 125°C (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)
• RoHS3 compliance status (exact match required)
• REACH unaffected classification (exact match required)

Substitute parts must originate from the same manufacturer (Cornell Dubilier Electronics) and maintain Active product status. Parts are grouped as direct equivalents only when all parameters listed above are identical.

Parameter Comparison

Engineering Selection Recommendations

The CMR03E430JOCP qualifies as a parametric equivalent to the CD5EC430JO3F based on complete alignment of all electrical, mechanical, and environmental specifications. Both parts are manufactured by Cornell Dubilier Electronics, maintain Active product status, and carry identical RoHS3 and REACH compliance certifications.

The primary distinction between these parts is series designation: CD5EC430JO3F belongs to the CD5 series, while CMR03E430JOCP belongs to the CMR series. This series difference reflects different product lines within the manufacturer's mica capacitor portfolio but does not affect functional equivalence when all specified parameters are identical.

Selection between these parts should be based on availability and supply chain requirements. The CD5EC430JO3F currently maintains higher inventory (1097 pieces) compared to the CMR03E430JOCP (673 pieces). Both parts are suitable for direct substitution in applications requiring 43 pF mica capacitors at 300 V with ±5% tolerance and through-hole radial mounting.

Frequently Asked Questions (FAQ)

Q: Can CMR03E430JOCP be used as a direct replacement for CD5EC430JO3F?

A: Yes. The CMR03E430JOCP is a parametric equivalent with identical capacitance (43 pF), tolerance (±5%), voltage rating (300 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.118" / 3.00 mm), physical dimensions, and compliance certifications (RoHS3, REACH unaffected).

Q: Are there any physical differences between these parts?

A: No physical differences exist in the specified parameters. Both parts have identical dimensions (0.272" L x 0.142" W / 6.90 mm x 3.60 mm), maximum seated height (0.209" / 5.30 mm), and lead spacing (0.118" / 3.00 mm). Both are through-hole radial packages suitable for identical PCB layouts.

Q: What is the difference between the CD5 and CMR series?

A: The CD5 and CMR series represent different product lines within Cornell Dubilier Electronics' mica capacitor portfolio. For the 43 pF 300 V specifications provided, both series offer identical electrical and mechanical characteristics. Series designation does not affect functional performance or substitution eligibility when all parameters match.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CD5EC430JO3F and CMR03E430JOCP carry ROHS3 Compliant status and are REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Which part should I select based on current availability?

A: Selection should be based on supply chain requirements and project timelines. CD5EC430JO3F has higher current inventory (1097 pieces) compared to CMR03E430JOCP (673 pieces). Both are in stock and available for immediate procurement.
