Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSF100J473 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 0.047 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 100V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (material family match)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Termination: PC Pins (exact match required)

Acceptable Variation Parameters:

• Operating Temperature Range: Substitute parts may exceed the original range
• Physical Dimensions: Minor variations acceptable if lead spacing and mounting footprint remain compatible
• Voltage Rating - AC: Presence of AC rating in substitute does not disqualify compatibility

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

168473J100C-F (Direct Substitute - Cornell Dubilier Electronics)

The 168473J100C-F is a direct substitute manufactured by the same supplier as the original DSF100J473. This part maintains identical electrical specifications (0.047 µF, ±5%, 100V DC) and mechanical compatibility (radial package, 5.00mm lead spacing, PC pin termination). The 168473J100C-F is in active production status, ensuring long-term availability. It carries ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part. The extended operating temperature range (-55°C ~ 125°C) provides enhanced thermal performance beyond the original specification. Physical dimensions are slightly reduced, resulting in a more compact footprint while maintaining identical lead spacing for PCB compatibility.

R82EC2470AA60J (Similar Substitute - KEMET)

The R82EC2470AA60J is a functionally equivalent substitute from KEMET, a major film capacitor manufacturer. This part matches all critical electrical parameters (0.047 µF, ±5%, 100V DC) and mechanical requirements (radial through-hole, 5.00mm lead spacing, PC pins). The R82EC2470AA60J is in active production and carries AEC-Q200 automotive qualification, indicating compliance with automotive-grade reliability standards. ROHS3 compliance and REACH unaffected status are maintained. The operating temperature range extends to -55°C ~ 105°C. Physical dimensions are equivalent to the 168473J100C-F, providing a compact profile. Selection of this part is appropriate for applications requiring automotive-grade component qualification or where KEMET supply chain integration is preferred.

Both substitute parts are electrically and mechanically compatible with the DSF100J473 and support direct replacement in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 168473J100C-F be used as a direct replacement for the DSF100J473?

A: Yes. The 168473J100C-F matches all critical electrical and mechanical parameters: 0.047 µF capacitance, ±5% tolerance, 100V DC rating, polyester metallized dielectric, radial through-hole package, 5.00mm lead spacing, and PC pin termination. Both parts are manufactured by Cornell Dubilier Electronics and carry identical regulatory compliance (ROHS3, REACH unaffected).

Q: What is the difference between the 168473J100C-F and R82EC2470AA60J?

A: Both parts are electrically equivalent (0.047 µF, ±5%, 100V DC) and mechanically compatible. The primary differences are: (1) Manufacturer: 168473J100C-F is Cornell Dubilier Electronics; R82EC2470AA60J is KEMET. (2) Automotive qualification: R82EC2470AA60J carries AEC-Q200 certification; 168473J100C-F does not. (3) Operating temperature: 168473J100C-F operates to 125°C; R82EC2470AA60J to 105°C. (4) Dielectric specification: R82EC2470AA60J explicitly specifies polyethylene terephthalate (PET) material.

Q: Are there physical size differences between the main part and substitutes?

A: Yes. The DSF100J473 measures 0.295" L x 0.126" W (7.50mm x 3.20mm) with a seated height of 0.315" (8.00mm). Both substitute parts measure 0.283" L x 0.098" W (7.20mm x 2.50mm) with seated heights of 0.256" (6.50mm) and 0.260" (6.60mm) respectively. The substitutes are more compact. However, lead spacing remains identical at 0.197" (5.00mm), ensuring PCB footprint compatibility. Verify available board space before selection if height clearance is constrained.

Q: Do the substitute parts have higher voltage ratings?

A: The substitute parts specify both AC and DC voltage ratings. The 168473J100C-F and R82EC2470AA60J both carry 63V AC and 100V DC ratings. The original DSF100J473 specifies only 100V DC with no AC rating listed. The DC rating of 100V matches the original specification exactly. The presence of an AC rating in the substitutes does not affect DC circuit compatibility.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both 168473J100C-F and R82EC2470AA60J carry ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the DSF100J473.

Q: Which substitute should I select for automotive applications?

A: The R82EC2470AA60J is qualified to AEC-Q200 automotive standards and is the appropriate selection for automotive applications. The 168473J100C-F does not carry automotive qualification.

Q: Can I use these substitutes in high-temperature environments?

A: Both substitute parts support extended operating temperature ranges. The 168473J100C-F operates from -55°C to 125°C, and the R82EC2470AA60J from -55°C to 105°C. Both exceed the original DSF100J473 specification of -40°C to 85°C. Verify that the specific application temperature profile falls within the selected part's rated range.
