Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSF100J823 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.082 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric material: Polyester, Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Lead spacing: 0.197" (5.00mm) (exact match required)
• Termination: PC Pins (exact match required)

Allowable Variation Parameters:

• Voltage rating: Substitute parts may have equal or higher DC voltage ratings than the original 100V specification
• Operating temperature range: Substitute parts may have equal or extended temperature ranges
• Physical dimensions: Minor variations in length, width, and height are acceptable provided the component fits within the original mounting footprint constraints
• Compliance certifications: Substitute parts must maintain ROHS3 compliance and REACH unaffected status

The ECQ-E2823JB qualifies as a direct substitute based on matching all mandatory parameters while providing enhanced voltage rating (250V DC) and extended operating temperature range (-40°C to 105°C).

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E2823JB is a qualified substitute for the DSF100J823 based on the following engineering criteria:

Electrical Equivalence: Both components share identical capacitance (0.082 µF) and tolerance (±5%) specifications. The ECQ-E2823JB provides a higher DC voltage rating (250V versus 100V), which is acceptable for applications originally designed for 100V operation. The substitute's extended operating temperature range (-40°C to 105°C versus -40°C to 85°C) supports broader environmental deployment scenarios.

Mechanical Compatibility: Lead spacing is identical at 0.197" (5.00mm), ensuring direct PCB footprint compatibility. The ECQ-E2823JB exhibits slightly larger physical dimensions (0.311" L x 0.213" W versus 0.295" L x 0.161" W) and greater seated height (0.378" versus 0.315"). Component placement verification is required to confirm clearance within the original assembly envelope.

Compliance and Supply: Both components maintain ROHS3 compliance and REACH unaffected status. The ECQ-E2823JB is actively manufactured by Panasonic Electronic Components with confirmed inventory availability (2488 pieces), whereas the DSF100J823 is obsolete. This substitution ensures long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E2823JB directly replace the DSF100J823 without circuit modification?

A: Yes, from an electrical standpoint. The ECQ-E2823JB matches all mandatory electrical parameters: capacitance, tolerance, and dielectric material. The higher voltage rating (250V) is backward-compatible with 100V applications. Physical verification of PCB clearance is required due to dimensional differences.

Q: What are the physical dimension differences, and do they affect installation?

A: The ECQ-E2823JB is slightly larger: 0.311" L x 0.213" W (versus 0.295" L x 0.161" W) with a maximum seated height of 0.378" (versus 0.315"). Lead spacing remains identical at 0.197" (5.00mm). Confirm that the substitute component fits within the available PCB space and does not contact adjacent components or enclosure walls.

Q: Are there any compliance or certification concerns with this substitution?

A: No. Both the DSF100J823 and ECQ-E2823JB are ROHS3 compliant and REACH unaffected. Regulatory and environmental compliance requirements are maintained through substitution.

Q: Why does the ECQ-E2823JB have a higher voltage rating?

A: Higher voltage ratings in film capacitors typically result from design improvements or different manufacturing processes. A 250V-rated component is suitable for 100V applications and provides additional safety margin. This does not negatively impact circuit performance.

Q: Is the ECQ-E2823JB available in the same packaging format?

A: The ECQ-E2823JB is supplied in bulk packaging, whereas the DSF100J823 packaging format is not specified in the available data. Both components use identical radial through-hole construction with PC pin termination, ensuring mechanical and electrical compatibility.

Q: What is the lead spacing, and is it critical for substitution?

A: Lead spacing is 0.197" (5.00mm) for both components. This parameter is critical for PCB footprint compatibility and is identical between the main part and substitute, ensuring direct mounting compatibility.
