Engineering Selection Recommendations

Both substitute parts LP333M016H9P3 and MAL205855333E3 provide functional equivalence to the obsolete ECE-S1CG333Z based on matching electrical and mechanical specifications. Selection between substitutes should consider the following factors:

LP333M016H9P3 (Cornell Dubilier Electronics): Active product status with ROHS3 compliance. Suitable for applications where standard lifetime requirements are acceptable. Lower lifetime rating (1000 hours @ 105°C) compared to the original part.

MAL205855333E3 (Vishay Beyschlag/Draloric/BC Components): Active product status with ROHS3 compliance and extended lifetime rating (5000 hours @ 105°C). Height dimension of 2.047" (52.00 mm) exceeds the original 1.969" (50.00 mm) by 2.047 mm, requiring verification of available mounting clearance in the target application. Suitable for applications requiring extended operational life.

Both parts are REACH Unaffected and carry EAR99 ECCN classification, matching the regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can LP333M016H9P3 and MAL205855333E3 be used interchangeably with ECE-S1CG333Z?

A: Both parts meet the core electrical and mechanical substitution criteria: 33000 µF capacitance, 16 V voltage rating, ±20% tolerance, radial snap-in package, 10.00 mm lead spacing, and 35.00 mm diameter. The MAL205855333E3 has a maximum seated height of 52.00 mm versus 50.00 mm for the original part, requiring clearance verification in the PCB assembly.

Q: What are the key differences between the substitute parts?

A: LP333M016H9P3 offers a standard lifetime of 1000 hours at 105°C, while MAL205855333E3 provides an extended lifetime of 5000 hours at 105°C. The MAL205855333E3 is 2.00 mm taller. Both are active products with ROHS3 compliance, whereas the original ECE-S1CG333Z is obsolete and RoHS non-compliant.

Q: Are there any mounting considerations when substituting these parts?

A: The MAL205855333E3 has a maximum seated height of 2.047" (52.00 mm) compared to 1.969" (50.00 mm) for the ECE-S1CG333Z. Verify available vertical clearance on the PCB assembly before selection. Lead spacing and diameter remain identical across all three parts.

Q: Do the substitute parts meet current regulatory requirements?

A: Both LP333M016H9P3 and MAL205855333E3 are ROHS3 compliant and REACH Unaffected, providing compliance with current environmental regulations. The original ECE-S1CG333Z is RoHS non-compliant.

Q: What is the significance of the different lifetime ratings?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C). The original part specifies 2000 hours, LP333M016H9P3 specifies 1000 hours, and MAL205855333E3 specifies 5000 hours. Application requirements determine the appropriate selection.
