Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-E1335KZ is determined by the following critical parameters:

• Capacitance Value: Must be 3.3 µF
• Tolerance: Must be ±10%
• Dielectric Type: Polyester, Metallized
• Mounting Configuration: Through-hole radial with PC pin termination
• Lead Spacing: 0.886" (22.50mm) for PCB compatibility
• Voltage Rating: Minimum 100V DC to maintain circuit safety margins

The ECQ-E2335KF meets all substitution criteria while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E2335KF is a direct functional substitute for the obsolete ECQ-E1335KZ. Both components share identical capacitance, tolerance, dielectric composition, and lead spacing specifications. The ECQ-E2335KF is currently in active production status with full inventory availability, addressing the obsolescence of the original part.

The ECQ-E2335KF provides enhanced electrical performance with a 250V DC rating compared to the 100V DC rating of the ECQ-E1335KZ, along with an extended operating temperature range of -40°C to 105°C. The substitute part carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

Physical dimensions show minimal variation between the two parts, with lead spacing remaining constant at 0.886" (22.50mm) for direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E2335KF replace the ECQ-E1335KZ in existing designs?

A: Yes. Both parts share identical capacitance (3.3 µF), tolerance (±10%), dielectric material (polyester metallized), lead spacing (22.50mm), and mounting configuration (through-hole radial). The substitute part is electrically and mechanically compatible.

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

A: Length varies from 1.004" (25.50mm) to 1.024" (26.00mm), and width from 0.394" (10.00mm) to 0.406" (10.30mm). Height-seated maximum decreases from 0.787" (20.00mm) to 0.748" (19.00mm). These minor variations do not affect PCB mounting compatibility due to identical lead spacing.

Q: Does the higher voltage rating of the ECQ-E2335KF affect circuit operation?

A: No. A component with higher voltage rating operates safely in circuits designed for lower voltages. The 250V DC rating of the ECQ-E2335KF provides additional safety margin in 100V DC applications.

Q: Are there temperature range considerations for substitution?

A: The ECQ-E2335KF operates across -40°C to 105°C, compared to -40°C to 85°C for the ECQ-E1335KZ. This extended range provides compatibility with a broader range of operating environments without performance degradation.

Q: What is the compliance status of the substitute part?

A: The ECQ-E2335KF is ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component distribution and use.
