DSF050J824 Equivalent & Substitute Parts

Part Overview

The DSF050J824 is a 0.82 µF film capacitor rated for 50V DC operation, manufactured by Cornell Dubilier Electronics (CDE) in the DSF series. This component features polyester metallized-stacked dielectric construction with radial through-hole mounting. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for general-purpose applications. Substitute parts must satisfy identical or superior electrical specifications and mechanical form factors to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSF050J824 is determined by the following mandatory parameters:

Electrical Equivalence Requirements:

• Capacitance value of 0.82 µF (exact match)
• DC voltage rating of 50V or higher
• Tolerance of ±5% or tighter
• Polyester metallized dielectric construction

Mechanical Compatibility Requirements:

• Through-hole radial mounting configuration
• Lead spacing of 0.197" (5.00mm)
• Physical dimensions compatible with PCB layout constraints

Regulatory and Compliance Requirements:

• ROHS3 compliance certification
• REACH unaffected status

The substitute part 168824J50G-F satisfies all mandatory electrical and mechanical parameters. The part exhibits superior operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) and active product status, making it a direct functional replacement. Physical dimensions show minor variations within acceptable tolerance for through-hole mounting applications.

Parameter Comparison

Engineering Selection Recommendations

The 168824J50G-F is a qualified direct substitute for the obsolete DSF050J824 based on the following engineering criteria:

Electrical Specifications: Both parts maintain identical capacitance (0.82 µF), tolerance (±5%), and DC voltage rating (50V). The substitute provides an additional AC voltage rating specification (30V) not present in the original part documentation.

Mechanical Compatibility: Lead spacing, mounting type, and maximum seated height are identical between both parts, ensuring PCB layout compatibility without modification. Minor variations in body dimensions (0.283" L x 0.236" W versus 0.287" L x 0.268" W) remain within acceptable tolerances for through-hole radial mounting applications.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement.

Product Availability: The substitute part maintains active manufacturing status with 903 units in stock, compared to the obsolete main part with limited remaining inventory of 944 units. The substitute exhibits an extended operating temperature range (-55°C ~ 125°C) that exceeds the original specification (-40°C ~ 85°C), providing enhanced thermal performance margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the 168824J50G-F be used as a direct replacement for the DSF050J824 without PCB modification?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00mm), mounting type (through-hole radial), and maximum seated height (0.433" / 11.00mm). PCB hole patterns and component placement require no modification.

Q: Are the electrical characteristics identical between these parts?

A: Electrical characteristics are functionally equivalent. Both parts provide 0.82 µF capacitance at ±5% tolerance with 50V DC rating. The substitute includes an additional 30V AC rating specification not documented for the original part.

Q: What is the significance of the extended operating temperature range in the substitute part?

A: The substitute operates across -55°C to 125°C compared to the original -40°C to 85°C range. This extended range provides greater thermal margin and compatibility with applications requiring operation in wider temperature environments.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the DSF050J824 and 168824J50G-F maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory standards for electronic component procurement and use.

Q: Why is the original part classified as obsolete?

A: The DSF050J824 is classified as obsolete due to discontinued manufacturing by Cornell Dubilier Electronics. The 168824J50G-F represents the active equivalent in the manufacturer's current product portfolio.

Q: Are there any physical dimension differences that affect component placement?

A: Minor variations exist in body length and width (0.283" L x 0.236" W for substitute versus 0.287" L x 0.268" W for original). These differences remain within acceptable tolerances for through-hole radial mounting and do not affect PCB layout compatibility.

Q: What dielectric material is used in both capacitors?

A: Both parts utilize polyester metallized dielectric construction. The original part specifies "stacked" configuration while the substitute specifies standard metallized construction. Both provide equivalent electrical performance for general-purpose applications.
