Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-E1683KF is determined by the following critical parameters:

• Capacitance Value: Must be 0.068 µF (exact match required)
• Voltage Rating (DC): Must be rated for minimum 100V DC
• Dielectric Type: Polyester or polyester-based metallized film
• Mounting Configuration: Through-hole radial package
• Lead Spacing: 0.197" (5.00mm) pitch for PCB compatibility
• Termination Style: PC pins for direct board insertion

The B32529C1683J000 meets all substitution criteria. While it features improved tolerance (±5% versus ±10%), a wider operating temperature range (-55°C ~ 125°C versus -40°C ~ 105°C), and enhanced reliability ratings (AEC-Q200), these represent performance enhancements rather than deviations from the core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The B32529C1683J000 is a direct functional substitute for the ECQ-E1683KF. Both components share identical capacitance values, DC voltage ratings, lead spacing, and through-hole radial package configuration, ensuring mechanical and electrical compatibility in PCB designs.

The B32529C1683J000 carries active product status, ensuring ongoing availability and supply chain support. It meets ROHS3 compliance requirements and holds AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring formal component traceability.

The substitute part's tighter tolerance (±5% versus ±10%) and extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 105°C) represent performance improvements that do not compromise compatibility with designs specified for the original ECQ-E1683KF.

Frequently Asked Questions (FAQ)

Q: Can the B32529C1683J000 be used as a direct replacement for the ECQ-E1683KF?

A: Yes. Both components have identical capacitance (0.068 µF), DC voltage rating (100V), lead spacing (5.00mm), and radial through-hole package configuration. PCB layout and electrical circuit performance remain unchanged.

Q: What is the significance of the tolerance difference (±10% versus ±5%)?

A: The B32529C1683J000's tighter tolerance provides improved capacitance accuracy. For applications where the original ±10% tolerance was acceptable, the ±5% tolerance of the substitute represents an enhancement with no negative impact on circuit operation.

Q: Does the extended operating temperature range of the B32529C1683J000 affect compatibility?

A: No. The substitute's wider temperature range (-55°C ~ 125°C versus -40°C ~ 105°C) is a performance enhancement. Designs specified for the original part's temperature range operate within the substitute's rated limits.

Q: Are there physical dimension differences between these parts?

A: Yes. The B32529C1683J000 has a smaller footprint (7.30mm L x 2.50mm W, 6.50mm seated height) compared to the ECQ-E1683KF (7.80mm L x 4.80mm W, 8.90mm seated height). Lead spacing remains identical at 5.00mm, ensuring PCB hole compatibility. Physical space constraints should be evaluated during layout review.

Q: What compliance certifications does the substitute part carry?

A: The B32529C1683J000 is ROHS3 compliant and holds AEC-Q200 automotive qualification. The original ECQ-E1683KF carries REACH Unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8532.25.0010.
