Parameter Comparison

Engineering Selection Recommendations

Both the MLP143M035EB1D and MLP143M035EB1A 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.

MLP143M035EB1D is the primary specification with 1065 units in current stock, providing the highest availability for immediate procurement.

MLP143M035EB1A is a direct parametric equivalent with 998 units in stock, suitable for use when primary part availability is constrained.

Both parts share identical electrical performance characteristics, mechanical dimensions, lead spacing, and mounting configuration. Both maintain the same compliance status (RoHS non-compliant, REACH Affected) and operational specifications across temperature, ripple current, and ESR parameters.

Selection should be based on delivery schedule and inventory allocation within the supply chain.

Frequently Asked Questions (FAQ)

Q: Are MLP143M035EB1D and MLP143M035EB1A electrically interchangeable?

A: Yes. Both parts are identical in capacitance (14000 µF), voltage rating (35 V), ESR (35 mOhm @ 120Hz), ripple current specifications, and operating temperature range (-55°C ~ 85°C). They are direct parametric equivalents.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts share identical mechanical specifications: FlatPack, Tabbed package, 1.000" (25.40mm) lead spacing, 3.000" L x 1.750" W dimensions, and 0.500" (12.70mm) maximum seated height. Chassis mount configuration and footprint are identical.

Q: What is the difference between MLP143M035EB1D and MLP143M035EB1A?

A: There are no electrical, mechanical, or performance differences between these parts. Both are manufactured by Cornell Dubilier Electronics in the MLP series with identical specifications. The difference is limited to part number designation and current inventory levels.
