Parameter Comparison

Engineering Selection Recommendations

Both the MLP331M420EB1C and MLP331M420EB0C are Active products manufactured by Cornell Dubilier Electronics within the MLP series. Selection between these parts is based on inventory availability and supply chain requirements rather than electrical or mechanical differentiation.

MLP331M420EB1C is the primary specification with 837 units in current inventory, providing the highest availability for immediate procurement.

MLP331M420EB0C is a direct parametric equivalent with 797 units in stock, suitable for use when primary part availability is constrained or for supply chain diversification within the same manufacturing series.

Both parts share identical compliance profiles: RoHS non-compliant status, REACH Affected designation, and MSL Level 1 (Unlimited moisture sensitivity). Selection does not require design modification, PCB layout changes, or thermal management adjustments.

Frequently Asked Questions (FAQ)

Q: Can MLP331M420EB0C be used as a direct replacement for MLP331M420EB1C in existing designs?

A: Yes. The MLP331M420EB0C is a parametric equivalent with identical electrical specifications (330 µF, 420 V, ±20% tolerance, 530 mOhm ESR @ 120Hz, 2000 Hrs @ 85°C), mechanical dimensions (FlatPack, 3.000" L x 1.750" W, 0.500" height, 1.000" lead spacing), and mounting configuration (Through Hole). No design changes are required.

Q: Are there any differences in thermal performance between these parts?

A: No. Both parts specify identical lifetime ratings of 2000 Hrs @ 85°C and identical operating temperature ranges of -40°C ~ 85°C. Ripple current handling is identical at both 120 Hz (2.1 A) and 20 kHz (2.5 A).

Q: What is the difference between MLP331M420EB1C and MLP331M420EB0C?

A: The parts are electrically and mechanically identical. The designation difference (EB1C vs. EB0C) reflects internal manufacturing or packaging variation within the CDE MLP series, but all specified parameters remain equivalent.

Q: Are both parts suitable for high-voltage applications at 420 V?

A: Yes. Both parts are rated for 420 V with identical ESR characteristics (530 mOhm @ 120Hz) and ripple current specifications. They are suitable for general-purpose high-voltage energy storage applications within the specified operating temperature range.

Q: What is the lead spacing for these FlatPack capacitors?

A: Both parts feature 1.000" (25.40mm) lead spacing, consistent with standard Through Hole FlatPack configuration. PCB pad spacing and mounting hole placement are identical.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts share identical compliance status: RoHS non-compliant, REACH Affected, MSL Level 1 (Unlimited), ECCN EAR99, and HTSUS 8532.22.0085. Regulatory and environmental handling requirements are identical.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability. MLP331M420EB1C currently has higher stock (837 Pcs vs. 797 Pcs), making it the preferred choice for immediate procurement. Both parts maintain Active product status with equivalent long-term availability.
