MLP281M450EB0D Equivalent & Substitute Parts

Part Overview

The MLP281M450EB0D is a 280 µF, 450 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the MLP series. This FlatPack, tabbed design with chassis mount configuration is an active product suitable for general-purpose applications requiring high-voltage energy storage and filtering. The need to identify substitute parts arises from inventory availability, procurement lead times, or design flexibility requirements in applications where parametric equivalents meet all electrical and mechanical specifications.

Substitute Part Grouping Explanation

The MLP281M450EB0D has one parametric equivalent substitute: MLP281M450EB1A. Substitution eligibility is determined by strict adherence to the following key parameters:

Capacitance Value: 280 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
ESR @ 120Hz: 585 mOhm (exact match required)
Lifetime @ Temperature: 2000 Hrs @ 85°C (exact match required)
Operating Temperature Range: -40°C ~ 85°C (exact match required)
Ripple Current Specifications: 2 A @ 120 Hz and 2.3 A @ 20 kHz (exact match required)
Physical Dimensions: 3.000" L × 1.750" W and 0.500" H (exact match required)
Package and Mounting: FlatPack, Tabbed, Chassis Mount (exact match required)
Lead Spacing: 1.000" (25.40 mm) (exact match required)

The MLP281M450EB1A satisfies all substitution criteria as an identical electrical and mechanical equivalent within the MLP series.

Engineering Selection Recommendations

Both the MLP281M450EB0D and MLP281M450EB1A are active products from Cornell Dubilier Electronics with identical electrical and mechanical specifications. The MLP281M450EB0D currently has 927 units in stock, while the MLP281M450EB1A has 714 units available. Both parts are RoHS non-compliant and REACH Affected, with moisture sensitivity level 1 (Unlimited). Selection between these parts should be based on inventory availability and procurement lead time requirements, as they are direct parametric equivalents suitable for interchangeable use in chassis-mount applications requiring 280 µF, 450 V aluminum electrolytic capacitors.

Frequently Asked Questions (FAQ)

Q: Are the MLP281M450EB0D and MLP281M450EB1A fully interchangeable?

A: Yes. Both parts are identical in all electrical parameters (capacitance, voltage, ESR, ripple current, and lifetime) and mechanical specifications (dimensions, lead spacing, package type, and mounting configuration). Direct substitution is electrically and mechanically valid.

Q: What determines if a part qualifies as a substitute for the MLP281M450EB0D?

A: A substitute must match all of the following: 280 µF capacitance, 450 V voltage rating, ±20% tolerance, 585 mOhm ESR @ 120Hz, 2000 Hrs @ 85°C lifetime, -40°C to 85°C operating range, 2 A @ 120 Hz and 2.3 A @ 20 kHz ripple current, 3.000" × 1.750" × 0.500" physical dimensions, 1.000" lead spacing, FlatPack tabbed package, and chassis mount configuration.

Q: Does the suffix difference between EB0D and EB1A affect functionality?

A: No functional difference exists. The suffix variation represents different manufacturing batches or procurement revisions within the same product family, but electrical and mechanical performance are identical.

Q: Are there compliance differences between these parts?

A: Both parts share identical regulatory status: RoHS non-compliant, REACH Affected, EAR99 classification, and HTSUS code 8532.22.0085. No compliance advantage exists between the two parts.

Q: What is the lead spacing requirement, and why does it matter?

A: Both parts have 1.000" (25.40 mm) lead spacing, which must match the PCB or chassis mounting holes. Mismatched lead spacing prevents proper installation.

Q: Can these parts be used in surface-mount applications?

A: No. Both MLP281M450EB0D and MLP281M450EB1A are chassis-mount components with tabbed leads designed for through-hole or chassis mounting, not surface-mount assembly.
