DSF050J563 Film Capacitor Equivalent & Substitute Parts

Part Overview

The DSF050J563 is a 0.056 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 50V DC operation with ±5% tolerance. This component features a polyester metallized-stacked radial construction and is designed for general-purpose applications. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. Substitute parts must maintain the same capacitance value, tolerance, and mechanical compatibility while meeting or exceeding the voltage rating and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSF050J563 is determined by strict adherence to the following critical parameters:

Electrical Compatibility Requirements:

• Capacitance value must equal 0.056 µF
• Tolerance must be ±5%
• Voltage rating (DC) must be equal to or greater than 50V
• Dielectric material must be polyester-based with metallized construction

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Package configuration must be Radial
• Lead spacing must be 0.197" (5.00mm)
• Termination must be PC Pins

Compliance Requirements:

• RoHS3 compliance required
• REACH Unaffected status required

Two substitute parts meet these criteria: the B32529C0563J000 (EPCOS - TDK Electronics) and the ECQ-E2563JB (Panasonic Electronic Components). Both parts satisfy all critical electrical and mechanical parameters while maintaining regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

B32529C0563J000 (EPCOS - TDK Electronics): This substitute provides a 63V DC rating, exceeding the 50V requirement of the original DSF050J563. The extended operating temperature range (-55°C ~ 125°C) offers broader environmental tolerance compared to the original specification (-40°C ~ 85°C). The part maintains identical capacitance, tolerance, and mechanical configuration. Active product status ensures ongoing availability and supply chain continuity. ROHS3 compliance and REACH Unaffected status satisfy regulatory requirements. This substitute is suitable for direct replacement in applications where the higher voltage rating and extended temperature range do not create design conflicts.

ECQ-E2563JB (Panasonic Electronic Components): This substitute provides a 250V DC rating, significantly exceeding the 50V requirement. The higher voltage rating introduces a larger physical footprint (0.311" L x 0.185" W versus 0.287" L x 0.126" W for the original part) and increased seated height (0.343" versus 0.236"). While mechanical compatibility is maintained through identical lead spacing and radial configuration, the dimensional increase may require PCB layout verification. Operating temperature range (-40°C ~ 105°C) extends the upper limit beyond the original specification. Active product status and full regulatory compliance are confirmed. This substitute is applicable when board space permits the larger package dimensions.

Frequently Asked Questions (FAQ)

Q: Can the B32529C0563J000 be used as a direct replacement for the DSF050J563?

A: Yes. The B32529C0563J000 maintains identical capacitance (0.056 µF), tolerance (±5%), lead spacing (5.00mm), and radial through-hole configuration. The 63V DC rating exceeds the 50V requirement, and the extended operating temperature range (-55°C ~ 125°C) provides additional environmental margin. No circuit modifications are required.

Q: What is the primary difference between the two substitute parts?

A: The B32529C0563J000 has a 63V DC rating and standard radial package dimensions. The ECQ-E2563JB has a 250V DC rating with a larger physical footprint (0.311" L x 0.185" W versus 0.287" L x 0.126" W) and increased seated height (0.343" versus 0.236"). Both maintain the same lead spacing and electrical specifications.

Q: Will the ECQ-E2563JB fit in the same PCB footprint as the DSF050J563?

A: The lead spacing (5.00mm) is identical, ensuring hole alignment compatibility. However, the larger body dimensions (0.311" L x 0.185" W and 0.343" seated height) may conflict with adjacent components or silkscreen markings. PCB layout verification is necessary before implementation.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both the B32529C0563J000 and ECQ-E2563JB are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the DSF050J563 classified as obsolete?

A: The DSF050J563 is no longer in active production by Cornell Dubilier Electronics. The substitute parts listed provide equivalent electrical and mechanical functionality with active product status, ensuring long-term supply chain availability.

Q: Can either substitute be used in automotive applications?

A: The B32529C0563J000 is specified for automotive applications and EMI/RFI suppression. The ECQ-E2563JB is specified for general-purpose applications. Application suitability depends on specific circuit requirements and environmental conditions beyond the scope of this substitution analysis.
