Substitute Part Grouping Explanation

Substitution eligibility for the ESMQ161ELL330MJ16S is determined by strict equivalence in the following parameters: capacitance value (33 µF), voltage rating (160 V), tolerance (±20%), polarization (Polar), mounting type (Through Hole), package type (Radial, Can), and lead spacing (0.197" / 5.00 mm). All identified substitute parts match these core electrical and mechanical specifications. Variations in lifetime rating, maximum operating temperature, ripple current characteristics, and case height are permitted within the substitute category, as these parameters do not affect direct functional interchangeability in the circuit application. All substitute parts maintain ROHS3 compliance and are classified as Active product status.

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original ESMQ161ELL330MJ16S. The EKXE161ELL330MJ16S (Chemi-Con KXE series) provides extended lifetime of 12000 hours at 105°C with identical case dimensions, supporting applications requiring enhanced thermal stability within the same footprint. The 160LEX33MEFC10X16 (Rubycon LEX series) extends maximum operating temperature to 125°C with 5000-hour lifetime at that temperature, suitable for high-temperature environments. The 160LLE33MEFC10X16 (Rubycon LLE series) delivers the longest operational life at 20000 hours at 105°C, addressing applications demanding maximum reliability and extended service intervals. Case height increases of 0.020" (0.50 mm) for Rubycon parts require verification of available PCB clearance. All parts share identical electrical ratings, lead spacing, and mounting configuration, confirming direct functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can EKXE161ELL330MJ16S replace ESMQ161ELL330MJ16S directly on the PCB?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00 mm), case diameter (0.394" / 10.00 mm), and seated height (0.689" / 17.50 mm). Electrical parameters—capacitance, voltage rating, and tolerance—are identical. Direct substitution is supported without circuit modification.

Q: What is the height difference between Chemi-Con and Rubycon substitute parts?

A: Chemi-Con EKXE161ELL330MJ16S maintains the original height of 0.689" (17.50 mm). Rubycon parts (160LEX33MEFC10X16 and 160LLE33MEFC10X16) have a maximum seated height of 0.709" (18.00 mm), representing a 0.020" (0.50 mm) increase. PCB clearance must be verified before substitution.

Q: Which substitute part offers the longest operational life?

A: The 160LLE33MEFC10X16 (Rubycon LLE series) provides 20000 hours at 105°C, the highest lifetime rating among all options. This part is suitable for applications requiring maximum reliability and extended maintenance intervals.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts—EKXE161ELL330MJ16S, 160LEX33MEFC10X16, and 160LLE33MEFC10X16—are ROHS3 compliant, matching the compliance status of the original ESMQ161ELL330MJ16S.

Q: What is the difference in ripple current ratings between the main part and substitutes?

A: The main part ESMQ161ELL330MJ16S supports 180 mA at 120 Hz and 324 mA at 100 kHz. EKXE161ELL330MJ16S supports 130 mA at 120 Hz and 325 mA at 100 kHz. Rubycon parts support 158 mA at 120 Hz and 284 mA at 100 kHz. Circuit ripple current requirements must be evaluated against these specifications.

Q: Can I use the 160LEX33MEFC10X16 in applications requiring operation above 105°C?

A: Yes. The 160LEX33MEFC10X16 is rated for operation up to 125°C, extending the maximum operating temperature by 20°C compared to the original part. This part is suitable for high-temperature applications within the 160 V voltage class.
