Substitute Part Grouping Explanation

Substitute parts for the LKSH2272MESZ are qualified based on the following criteria:

Electrical Compatibility:

Capacitance: 2700 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 80 V minimum (exceeds original 71 V rating, providing design margin)
Polarization: Polar (exact match required)

Mechanical Compatibility:

Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Physical Diameter: 0.866" (22.00 mm) (exact match required)
Height: 1.654" (42.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)

Environmental Compatibility:

Operating Temperature Range: -40°C to 85°C minimum (all substitutes meet or exceed this range)

All three substitute parts meet these criteria and are direct mechanical and electrical replacements for the obsolete LKSH2272MESZ.

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, providing long-term availability compared to the obsolete LKSH2272MESZ.

LLS1K272MELZ (Nichicon): This part maintains the same manufacturer as the original component, ensuring consistency in design heritage and performance characteristics. It offers improved lifetime specifications (3000 hours at 85°C versus 1000 hours) and is ROHS3 compliant. This option is suitable for designs requiring manufacturer continuity.

80MXG2700MEFCSN22X40 (Rubycon): This part provides the highest operating temperature range (-40°C to 105°C) and extended lifetime at elevated temperature (3000 hours at 105°C). It is ROHS3 compliant and offers the broadest thermal operating envelope. This option is suitable for applications requiring enhanced thermal performance.

B41231A278M (EPCOS - TDK Electronics): This part offers the highest ripple current rating at 120 Hz (3.79 A) and is ROHS3 compliant. It provides a 2000-hour lifetime at 85°C. This option is suitable for applications with demanding ripple current requirements.

All three parts are mechanically and electrically interchangeable with the original LKSH2272MESZ within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the LKSH2272MESZ be directly replaced with any of these substitute parts?

A: Yes. All three substitute parts are direct replacements. They share identical capacitance (2700 µF), tolerance (±20%), package type (radial, can snap-in), lead spacing (10.00 mm), physical dimensions (22.00 mm diameter, 42.00 mm height), and mounting type (through hole). The substitute parts have higher voltage ratings (80 V versus 71 V), which provides additional design margin.

Q: What is the difference between the three substitute options?

A: The primary differences are manufacturer, lifetime specifications, operating temperature range, and ripple current ratings. LLS1K272MELZ maintains Nichicon manufacturing. 80MXG2700MEFCSN22X40 offers the highest operating temperature (105°C). B41231A278M provides the highest ripple current capability (3.79 A at 120 Hz).

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Will the higher voltage rating (80 V) of the substitute parts affect circuit performance?

A: No. A higher voltage rating does not negatively affect circuit performance. The capacitor will function identically in circuits designed for 71 V operation. The higher rating provides additional safety margin and component longevity.

Q: Are the physical dimensions identical between the original and substitute parts?

A: Yes. All parts share identical physical dimensions: 22.00 mm diameter, 42.00 mm height, and 10.00 mm lead spacing. They are mechanically interchangeable in through-hole applications.

Q: Which substitute part should be selected for audio applications?

A: The original LKSH2272MESZ was specified for audio applications. All three substitute parts are electrically compatible and can be used in audio circuits. Selection should be based on specific performance requirements such as ripple current handling, thermal environment, or manufacturer preference.
