Equivalent & Substitute Parts for 160394J63C-F

Part Overview

The Cornell Dubilier Electronics (CDE) 160394J63C-F is a 0.39 µF film capacitor with polyester metallized dielectric, rated for 63V DC operation. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives from the active product portfolio. The radial through-hole configuration and ±5% tolerance make this part suitable for general-purpose applications requiring stable capacitance across the specified operating temperature range of -55°C to 105°C.

Substitute Part Grouping Explanation

Substitution of the 160394J63C-F is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 0.39 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric material: Polyester, Metallized (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Termination: PC Pins (exact match required)

Allowable Variation Parameters:

• Voltage rating (DC): Equal to or greater than 63V
• Physical dimensions: May increase with higher voltage rating
• Product status: Active status preferred for long-term availability

The substitute part 160394J100D-F meets all primary matching parameters and provides a higher voltage rating (100V DC), making it suitable for applications where the original 63V specification can accommodate the increased voltage capability.

Parameter Comparison

Engineering Selection Recommendations

The 160394J100D-F serves as a direct functional substitute for the obsolete 160394J63C-F based on the following engineering criteria:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and manufacturing environments.

Product Availability: The 160394J100D-F carries active product status with 859 units in stock, compared to the obsolete status of the original part. This ensures long-term supply chain continuity and support.

Electrical Compatibility: The substitute part maintains identical capacitance (0.39 µF) and tolerance (±5%), with a higher voltage rating (100V DC versus 63V DC). This higher rating provides additional design margin without altering the electrical performance in applications operating at or below 63V DC.

Mechanical Compatibility: Lead spacing remains constant at 0.394" (10.00 mm), ensuring direct PCB footprint compatibility. Physical dimension increases (width and height) are accommodated by the higher voltage rating and do not affect electrical function.

Temperature Performance: Operating temperature range remains -55°C to 105°C, maintaining thermal performance specifications across both parts.

Frequently Asked Questions (FAQ)

Q: Can the 160394J100D-F be used as a direct replacement for the 160394J63C-F?

A: Yes. The substitute part maintains identical capacitance, tolerance, dielectric material, lead spacing, and termination type. The higher voltage rating (100V versus 63V) does not prevent substitution in applications operating at 63V or lower.

Q: Will the larger physical dimensions of the 160394J100D-F cause PCB layout issues?

A: The lead spacing remains identical at 0.394" (10.00 mm), ensuring footprint compatibility. Width increases from 0.157" to 0.236" and height from 0.374" to 0.472". PCB layout must accommodate these increased dimensions, but the radial through-hole mounting configuration remains unchanged.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory and environmental compliance status is equivalent.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The 100V DC rating on the 160394J100D-F provides additional voltage margin compared to the 63V DC rating of the original part. In applications operating at 63V or lower, this higher rating does not affect performance but may improve reliability through reduced electrical stress.

Q: Is the 160394J100D-F suitable for AC applications?

A: The substitute part is rated for 63V AC, compared to 40V AC on the original part. AC voltage compatibility depends on specific application requirements and circuit design.
