Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSF100J563 is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must be 0.056 µF
• Tolerance must be ±5%
• Voltage rating must equal or exceed 100V DC
• Dielectric material must be polyester, metallized construction

Mechanical Compatibility:

• Mounting type must be through-hole
• Package configuration must be radial
• Lead spacing must be 0.197" (5.00mm)
• Termination must be PC pins

Environmental & Compliance:

• Operating temperature range must encompass or exceed -40°C to 85°C
• RoHS3 compliance required
• REACH unaffected status required

The ECQ-E2563JB meets all substitution criteria. It provides identical capacitance and tolerance values, maintains the same lead spacing and radial configuration, and exceeds the voltage rating requirement with 250V DC capability. The substitute part operates across an extended temperature range (-40°C to 105°C) and maintains full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E2563JB is a direct substitute for the DSF100J563 based on the following engineering criteria:

Electrical Equivalence: Both components share identical capacitance (0.056 µF) and tolerance (±5%) specifications. The ECQ-E2563JB provides a higher voltage rating (250V DC versus 100V DC), which is acceptable for applications designed for the lower voltage specification and does not introduce functional incompatibility.

Mechanical Compatibility: Lead spacing, termination type, and radial package configuration are identical between the two parts. Physical dimensions of the substitute are slightly larger (0.311" L x 0.185" W versus 0.295" L x 0.126" W), which must be verified against available PCB layout space and component clearance requirements.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.

Product Availability: The ECQ-E2563JB is classified as active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete DSF100J563.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E2563JB be used as a direct replacement for the DSF100J563?

A: Yes. The ECQ-E2563JB meets all electrical and mechanical substitution criteria. Capacitance, tolerance, lead spacing, and mounting configuration are identical. The substitute provides higher voltage rating capability, which is compatible with applications designed for the original 100V specification.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The ECQ-E2563JB operates at 250V DC compared to the DSF100J563 at 100V DC. A higher voltage rating does not create incompatibility in circuits designed for lower voltage operation. The substitute part will function correctly in the original application.

Q: Are there physical size differences between these parts?

A: Yes. The ECQ-E2563JB is slightly larger in length and width (0.311" L x 0.185" W versus 0.295" L x 0.126" W) and has a greater seated height (0.343" versus 0.315"). Lead spacing remains identical at 0.197" (5.00mm). PCB layout and component clearance must be verified before substitution.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the DSF100J563 and ECQ-E2563JB are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory standards.

Q: What is the operating temperature difference between these parts?

A: The DSF100J563 operates from -40°C to 85°C, while the ECQ-E2563JB operates from -40°C to 105°C. The substitute part provides an extended upper temperature limit, which is compatible with applications designed for the original temperature range.

Q: Is the ECQ-E2563JB available in the same packaging format?

A: Both parts are supplied in radial through-hole configuration with PC pin termination. The ECQ-E2563JB is available as active product, ensuring supply availability. The DSF100J563 is obsolete and subject to limited availability.
