CD5EC390JO3 Equivalent & Substitute Parts

Part Overview

The CD5EC390JO3 is a 39 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD5 series. This through-hole radial component operates at 300 V rated voltage with ±5% tolerance and is classified as a general-purpose capacitor. The part is currently active in production with 703 units in stock.

Mica capacitors in this specification are used in applications requiring stable capacitance over temperature ranges, low dielectric loss, and reliable performance in RF and precision analog circuits. Identifying equivalent substitute parts is necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design revisions necessitate component alternatives that maintain identical electrical and mechanical performance.

• Package / Case: Radial
• Lead Spacing: 0.118" (3.00 mm)
• Physical Dimensions: 0.272" L x 0.130" W (6.90 mm x 3.30 mm)
• Height - Seated (Max): 0.209" (5.30 mm)

Environmental Parameters (Non-negotiable):

• Operating Temperature Range: -55°C to 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

The CD5EC390JO3F meets all substitution criteria as a parametric equivalent within the CD5 series from Cornell Dubilier Electronics.

Parameter Comparison

Engineering Selection Recommendations

CD5EC390JO3F as Primary Substitute:

The CD5EC390JO3F is a direct parametric equivalent to the CD5EC390JO3 across all electrical, mechanical, and environmental specifications. Both parts are manufactured by Cornell Dubilier Electronics within the CD5 series and maintain identical performance characteristics for capacitance, voltage rating, temperature range, and physical form factor.

Compliance Considerations:

The CD5EC390JO3F offers improved regulatory compliance status compared to the main part. The substitute achieves ROHS3 compliance, whereas the CD5EC390JO3 is RoHS non-compliant. Additionally, the CD5EC390JO3F is REACH Unaffected, compared to the main part's REACH Affected status. These differences are relevant for applications subject to environmental regulations in specific jurisdictions.

Availability:

The CD5EC390JO3F maintains higher inventory availability with 973 units in stock compared to 703 units of the main part, supporting supply chain continuity.

Application Compatibility:

Both parts are suitable for identical circuit applications requiring 39 pF capacitance at 300 V with ±5% tolerance in through-hole radial configuration. No circuit redesign or board layout modification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can CD5EC390JO3F be used as a direct replacement for CD5EC390JO3 in existing designs?

A: Yes. The CD5EC390JO3F is a parametric equivalent with identical electrical and mechanical specifications. No circuit modifications, board layout changes, or design revisions are required. Both parts are manufactured by Cornell Dubilier Electronics in the CD5 series with matching capacitance (39 pF), voltage rating (300 V), tolerance (±5%), and physical dimensions.

Q: What is the difference between CD5EC390JO3 and CD5EC390JO3F?

A: The primary differences are regulatory compliance and inventory status. The CD5EC390JO3F is ROHS3 compliant and REACH Unaffected, whereas the CD5EC390JO3 is RoHS non-compliant and REACH Affected. All electrical and mechanical parameters are identical. The CD5EC390JO3F also has higher inventory availability (973 units versus 703 units).

Q: Are the physical dimensions and lead spacing identical between these parts?

A: Yes. Both parts share identical physical dimensions of 0.272" L x 0.130" W (6.90 mm x 3.30 mm), maximum seated height of 0.209" (5.30 mm), and lead spacing of 0.118" (3.00 mm). They are both radial through-hole components with identical PCB footprints.

Q: Do these parts have the same operating temperature range?

A: Yes. Both CD5EC390JO3 and CD5EC390JO3F operate across the identical temperature range of -55°C to 125°C with stable mica dielectric performance.

Q: Which part should be selected for new designs?

A: Selection should be based on regulatory requirements applicable to the end application. For applications requiring RoHS3 compliance or REACH compliance, the CD5EC390JO3F is the appropriate choice. For applications without such regulatory constraints, either part is functionally equivalent. The CD5EC390JO3F offers the additional benefit of higher inventory availability.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
