• Tolerance: ±20%
• ESR: 399 mOhm @ 120 Hz
• Lifetime specification: 2000 Hrs @ 85°C
• Operating temperature range: -40°C to 85°C
• Ripple current ratings: 2.1 A @ 120 Hz and 2.5 A @ 20 kHz

Mechanical Equivalence Criteria:

• Package type: FlatPack, Tabbed
• Lead spacing: 1.000" (25.40 mm)
• Physical dimensions: 2.000" L × 1.750" W (50.80 mm × 44.45 mm)
• Height (seated): 0.500" (12.70 mm) maximum
• Mounting type: Chassis Mount
• Polarization: Polar

The substitute part MLP331M300EA0D shares identical specifications across all electrical and mechanical parameters, confirming direct substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the MLP331M300EA0D and MLP331M300EA0A are active production parts from Cornell Dubilier Electronics with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain considerations rather than technical differentiation.

MLP331M300EA0D is the primary part number with 1100 units currently in stock.

MLP331M300EA0A is the direct substitute with 1097 units currently in stock, providing equivalent performance and compatibility.

Both parts share identical compliance status: RoHS non-compliant and REACH Affected. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Selection of either part number is appropriate for applications requiring 330 µF, 300 V aluminum electrolytic capacitors with FlatPack, tabbed chassis mount configuration and the specified electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can MLP331M300EA0A be used as a direct replacement for MLP331M300EA0D?

A: Yes. Both parts are identical in capacitance (330 µF), voltage rating (300 V), tolerance (±20%), ESR (399 mOhm @ 120 Hz), lifetime (2000 Hrs @ 85°C), operating temperature range (-40°C to 85°C), ripple current ratings, physical dimensions, lead spacing, package type (FlatPack, Tabbed), and mounting configuration (Chassis Mount). Direct substitution is supported without circuit modification.

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

A: No. Both MLP331M300EA0D and MLP331M300EA0A share identical compliance status: RoHS non-compliant, REACH Affected, and Moisture Sensitivity Level 1 (Unlimited). No compliance differences exist between the two part numbers.

Q: What is the significance of the different suffix letters (EA0D vs. EA0A) in the part numbers?

A: The suffix letters indicate internal manufacturing or packaging variations within the same electrical and mechanical specification. Both parts meet identical performance requirements and are interchangeable in circuit applications.

Q: Are these parts suitable for high-ripple-current applications?

A: These capacitors support ripple current ratings of 2.1 A @ 120 Hz and 2.5 A @ 20 kHz. Application suitability depends on circuit ripple current requirements relative to these specifications.

Q: What is the lead spacing and how does it affect PCB layout?

A: Lead spacing is 1.000" (25.40 mm) for both parts. This spacing must be accommodated in PCB hole pattern design for chassis mount installation. Physical dimensions are 2.000" L × 1.750" W (50.80 mm × 44.45 mm) with maximum seated height of 0.500" (12.70 mm).

Q: Can these capacitors be used in applications requiring RoHS compliance?

A: No. Both MLP331M300EA0D and MLP331M300EA0A are RoHS non-compliant. Applications with RoHS compliance requirements must use alternative capacitor part numbers.
