DSF050J153 Equivalent & Substitute Parts

Part Overview

The DSF050J153 is a 0.015 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 and ±5% tolerance. The part is classified as obsolete, necessitating identification of equivalent alternatives from active manufacturers for continued circuit implementation and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSF050J153 is determined by strict equivalence in the following parameters: capacitance value (0.015 µF), tolerance (±5%), mounting type (through-hole radial), lead spacing (0.197" / 5.00mm), and termination style (PC pins). All substitute parts must maintain these core electrical and mechanical specifications.

Voltage rating substitution is permissible when the alternative part meets or exceeds the original 50V DC requirement, as higher voltage ratings provide equivalent or superior performance in the same circuit application. Dielectric material composition (polyester-based formulations) and operating temperature ranges may vary within the substitute group while maintaining functional compatibility.

The three identified substitute parts—B32529C0153J000 (EPCOS), ECQ-E2153JB (Panasonic), and R82EC2150AA50J (KEMET)—satisfy these substitution criteria and are sourced from active manufacturers with current production status.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are sourced from active manufacturers with current production status, ensuring long-term availability and supply chain continuity compared to the obsolete DSF050J153.

B32529C0153J000 (EPCOS - TDK Electronics): This part provides the closest voltage margin above the original 50V specification at 63V DC. It carries AEC-Q200 automotive qualification and supports an extended operating temperature range of -55°C to 125°C. Physical dimensions are compact (7.30mm L × 2.50mm W), and it is classified as active with high inventory availability.

ECQ-E2153JB (Panasonic Electronic Components): This part offers the highest voltage rating at 250V DC, providing maximum design margin for applications requiring enhanced voltage headroom. It maintains the -40°C to 105°C operating temperature range aligned with the original specification. Physical dimensions are larger (7.90mm L × 4.20mm W), and it is active with substantial inventory.

R82EC2150AA50J (KEMET): This part provides 100V DC rating with AEC-Q200 automotive qualification. It supports an extended operating temperature range of -55°C to 105°C and features compact dimensions (7.20mm L × 2.50mm W). It is active with high inventory availability.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can the DSF050J153 be directly replaced with any of these substitute parts?

A: Yes. All three substitute parts maintain identical capacitance (0.015 µF), tolerance (±5%), lead spacing (0.197" / 5.00mm), mounting type (through-hole radial), and termination style (PC pins). The higher voltage ratings of the substitutes (63V, 100V, and 250V) are compatible with the original 50V application.

Q: What is the significance of the higher voltage ratings in the substitute parts?

A: Higher voltage ratings indicate greater electrical stress margin. A 63V, 100V, or 250V rated capacitor can be used in a 50V circuit without performance degradation. The voltage rating reflects the maximum safe operating voltage; operation below this rating is standard practice.

Q: Do the physical dimension differences affect PCB compatibility?

A: Lead spacing remains constant at 0.197" (5.00mm) across all parts, ensuring PCB footprint compatibility. Length and width dimensions vary slightly (7.20mm to 7.90mm length; 2.50mm to 4.20mm width), but these variations are within typical through-hole component tolerances and do not affect mounting hole alignment or circuit board layout.

Q: Which substitute part should be selected for automotive applications?

A: Both B32529C0153J000 and R82EC2150AA50J carry AEC-Q200 automotive qualification. These parts are suitable for automotive circuit implementations. ECQ-E2153JB does not list automotive qualification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original DSF050J153.

Q: What is the difference between the operating temperature ranges?

A: The original DSF050J153 operates from -40°C to 85°C. The substitute parts offer extended ranges: B32529C0153J000 (-55°C to 125°C), ECQ-E2153JB (-40°C to 105°C), and R82EC2150AA50J (-55°C to 105°C). Extended temperature ranges provide operational capability in more demanding thermal environments.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes, within the constraints of physical space and thermal requirements. All parts share the same electrical specifications (capacitance, tolerance, lead spacing) and mounting configuration. Physical dimension variations should be verified against PCB layout constraints before implementation.
