Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-B2102JF is determined by the following critical parameters:

• Capacitance Value: Must be 1000 pF
• Tolerance: Must be ±5% or tighter
• Voltage Rating - DC: Must be equal to or greater than 200V
• Dielectric Material: Polyester or compatible film material
• Mounting Type: Through Hole
• Package Configuration: Radial
• Lead Spacing: 0.197" (5.00mm)

The B32529C3102J000 from EPCOS - TDK Electronics meets these substitution criteria with a 250V DC rating, providing voltage margin above the original specification, and maintains identical lead spacing and radial configuration.

Engineering Selection Recommendations

The B32529C3102J000 is a direct functional substitute for the ECQ-B2102JF. Key selection factors include:

• Voltage Margin: The substitute provides 250V DC rating versus the original 200V specification, offering additional safety margin in circuit operation.
• Product Availability: The substitute is in active production status with 18,315 pieces in stock, ensuring supply continuity compared to the obsolete original component.
• Compliance: The B32529C3102J000 carries AEC-Q200 automotive qualification and ROHS3 compliance, meeting modern regulatory requirements.
• Temperature Range: The extended operating range (-55°C ~ 125°C) of the substitute accommodates broader environmental conditions than the original (-40°C ~ 105°C).
• Physical Compatibility: Identical lead spacing (5.00mm) and radial configuration ensure direct board-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the B32529C3102J000 be used as a direct replacement for the ECQ-B2102JF?

A: Yes. Both components share identical capacitance (1000 pF), tolerance (±5%), lead spacing (5.00mm), and radial package configuration. The substitute's higher voltage rating (250V vs. 200V) and extended temperature range provide additional operational margin.

Q: What are the physical dimension differences between these parts?

A: The ECQ-B2102JF measures 0.335" L x 0.157" W with 0.315" seated height. The B32529C3102J000 measures 0.287" L x 0.098" W with 0.256" seated height. Both maintain the same 0.197" (5.00mm) lead spacing, though the substitute is physically more compact.

Q: Are there any compliance or certification differences?

A: The B32529C3102J000 includes AEC-Q200 automotive qualification and ROHS3 compliance. The original ECQ-B2102JF specifications do not list these certifications. Both components are EAR99 classified and not subject to REACH restrictions.

Q: What is the voltage derating consideration for this substitution?

A: The substitute operates at 250V DC versus the original 200V specification. This 50V margin (25% overvoltage capability) provides additional safety in circuit design without requiring derating adjustments.

Q: Are the dielectric materials compatible?

A: Both components use polyester-based dielectrics. The substitute specifies polyester with polyethylene terephthalate (PET) metallized-stacked construction, which is compatible with polyester film applications.
