Parameter Comparison

Engineering Selection Recommendations

The ECE-A1CKA330 is the appropriate substitute for the obsolete B41002A4336M. Both components are ROHS3 compliant and maintain identical electrical specifications for capacitance, voltage rating, tolerance, and operating temperature range. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The ECE-A1CKA330 exhibits higher ripple current ratings at both 120 Hz (60 mA versus 55 mA) and 10 kHz (102 mA versus 66 mA), providing improved performance margin in ripple-current-sensitive applications. The substitute part has a slightly reduced seated height (7.00mm versus 8.00mm), which may provide a minor advantage in space-constrained PCB layouts while maintaining identical lead spacing and diameter specifications for direct mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ECE-A1CKA330 be used as a direct replacement for the B41002A4336M?

A: Yes. Both components share identical capacitance (33 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-40°C ~ 85°C), lifetime rating (1000 Hrs @ 85°C), lead spacing (2.00mm), and package configuration (Radial, Can). The substitute part is mechanically and electrically compatible for direct PCB substitution.

Q: What are the differences between these two parts?

A: The primary differences are product status and ripple current performance. The B41002A4336M is obsolete, while the ECE-A1CKA330 is in active production. The ECE-A1CKA330 provides higher ripple current ratings (60 mA @ 120 Hz and 102 mA @ 10 kHz compared to 55 mA and 66 mA respectively) and a slightly reduced seated height (7.00mm versus 8.00mm).

Q: Are there any PCB layout considerations when substituting these parts?

A: No significant layout changes are required. Both parts maintain identical lead spacing (2.00mm) and diameter (5.00mm). The ECE-A1CKA330 has a 1.00mm reduction in seated height, which does not affect through-hole mounting compatibility or circuit board design.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the B41002A4336M and ECE-A1CKA330 are ROHS3 compliant. The ECE-A1CKA330 additionally carries REACH Unaffected status.
