Engineering Selection Recommendations

Both substitute parts are electrically and mechanically equivalent to the B41002A7336M and are suitable for direct replacement in through-hole applications.

EKMA350ELL330MF07D (Chemi-Con KMA Series): This direct substitute maintains identical electrical specifications and physical dimensions. The part is active in production and ROHS3 compliant. The extended operating temperature range (-55°C ~ 105°C) provides additional thermal margin compared to the original part. This option is recommended for applications requiring immediate availability and long-term supply continuity.

336PUM035M (Cornell Dubilier / Illinois Capacitor PUM Series): This upgrade substitute offers extended lifetime rating (2000 hours at 85°C versus 1000 hours) and specified ESR characteristics (6.029 Ohm @ 120 Hz). The part is active in production and ROHS3 compliant. This option is recommended for applications where enhanced reliability and lower equivalent series resistance are beneficial.

Frequently Asked Questions (FAQ)

Q: Can EKMA350ELL330MF07D be used as a direct replacement for B41002A7336M?

A: Yes. Both parts share identical capacitance (33 µF), voltage rating (35 V), tolerance (±20%), and physical dimensions (0.248" diameter, 0.315" height, 0.098" lead spacing). The radial, can package and through-hole mounting are identical. No circuit modifications are required.

Q: Can 336PUM035M be used as a direct replacement for B41002A7336M?

Q: What is the difference between the two substitute parts?

A: EKMA350ELL330MF07D offers an extended operating temperature range (-55°C ~ 105°C) and is rated for 1000 hours at 105°C. The 336PUM035M provides a longer lifetime rating (2000 hours at 85°C) and includes specified ESR characteristics. Both are electrically and mechanically equivalent to the original part.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both EKMA350ELL330MF07D and 336PUM035M are ROHS3 compliant, matching the compliance status of the B41002A7336M.

Q: Will the substitute parts fit the existing PCB layout?

A: Yes. Both substitute parts maintain the identical lead spacing (0.098" / 2.50 mm), case diameter (0.248" / 6.30 mm), and height (0.315" / 8.00 mm). No PCB modifications are necessary.

Q: Which substitute should I choose for new designs?

A: Selection depends on application requirements. For standard general-purpose filtering with extended temperature capability, EKMA350ELL330MF07D is suitable. For applications requiring enhanced reliability and lower ESR, 336PUM035M is recommended. Both are active in production and support long-term supply continuity.
