Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKSH2102MESZ is determined by the following critical parameters:

• Capacitance Value: 1000 µF (exact match required)
• Voltage Rating: Minimum 71 V (equal or higher voltage rating acceptable)
• Package Type: Radial, Can - Snap-In (mechanical and electrical compatibility)
• Lead Spacing: 0.394" (10.00mm) (PCB footprint compatibility)
• Polarization: Polar (functional requirement)
• Operating Temperature Range: -40°C ~ 85°C (environmental compatibility)

The substitute part MAL205659102E3 meets all substitution criteria with a higher voltage rating (100 V) and improved lifetime specification (12000 Hrs @ 85°C versus 1000 Hrs @ 85°C), providing enhanced reliability margins in the same physical package configuration.

Parameter Comparison

Engineering Selection Recommendations

The MAL205659102E3 is a direct functional substitute for the LKSH2102MESZ. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete LKSH2102MESZ.

The substitute provides improved reliability with a 12-fold increase in lifetime specification (12000 Hrs @ 85°C versus 1000 Hrs @ 85°C). The higher voltage rating (100 V versus 71 V) provides additional safety margin in circuit operation.

Physical dimensions differ: the substitute is larger in diameter (0.984" versus 0.866") and height (1.260" versus 0.866"). Lead spacing remains identical at 0.394" (10.00mm), ensuring PCB footprint compatibility. Design verification is required to confirm adequate clearance in the target application.

The substitute is ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and end-of-life management.

Frequently Asked Questions (FAQ)

Q: Can MAL205659102E3 directly replace LKSH2102MESZ without circuit modification?

A: The substitute part maintains identical capacitance (1000 µF), tolerance (±20%), operating temperature range (-40°C ~ 85°C), lead spacing (10.00mm), and package type (Radial, Can - Snap-In). The higher voltage rating (100 V) is electrically compatible with the original 71 V specification. Physical dimensions differ; PCB layout verification is required to confirm adequate component clearance.

Q: What are the key differences between these parts?

A: The primary differences are: voltage rating (71 V versus 100 V), lifetime specification (1000 Hrs @ 85°C versus 12000 Hrs @ 85°C), physical dimensions (diameter and height), ESR specification (not provided for original versus 265 mOhm @ 100Hz for substitute), and product status (obsolete versus active). Capacitance and tolerance are identical.

Q: Is the larger physical size of MAL205659102E3 a concern?

A: The substitute is larger in both diameter (0.984" versus 0.866") and height (1.260" versus 0.866"). Lead spacing remains unchanged at 0.394" (10.00mm). Design verification is necessary to confirm adequate clearance in the target PCB layout and enclosure.

Q: Does the higher voltage rating affect circuit performance?

A: A higher voltage rating does not degrade circuit performance. The 100 V rating of the substitute provides additional safety margin compared to the 71 V original specification. The capacitance value and tolerance remain identical, ensuring equivalent electrical behavior in the circuit.

Q: Are there compliance or regulatory differences?

A: The substitute (MAL205659102E3) is ROHS3 compliant, meeting current regulatory requirements. Both parts maintain REACH Unaffected status. The substitute's active production status ensures compliance with current manufacturing standards.
