Equivalent & Substitute Parts for LNT2E681MSEN

Part Overview

The LNT2E681MSEN is a 680 µF, 250 V aluminum electrolytic capacitor with radial, can-style screw terminals manufactured by Nichicon. This component is designed for general-purpose applications requiring high-capacitance energy storage in chassis-mounted configurations. The part is currently active in production with 875 units in stock. Substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory levels require alternative sourcing while maintaining full electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the LNT2E681MSEN is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 680 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime Specification: 2000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -25°C ~ 105°C (exact match required)
• Ripple Current Ratings: 1.4 A @ 120 Hz and 1.68 A @ 10 kHz (exact match required)
• Physical Dimensions: Lead spacing 0.500" (12.70 mm), diameter 1.378" (35.00 mm), height 3.268" (83.00 mm) (exact match required)
• Mounting Configuration: Chassis Mount with Radial, Can - Screw Terminals (exact match required)
• Compliance: ROHS3 Compliant and REACH Affected status (exact match required)

The substitute part LNT2E681MSE meets all these criteria and is therefore a direct parametric equivalent suitable for interchangeable use in applications currently specified for the LNT2E681MSEN.

Parameter Comparison

Engineering Selection Recommendations

Both the LNT2E681MSEN and LNT2E681MSE are manufactured by Nichicon and maintain active product status. Selection between these parts should be based on inventory availability and supply chain requirements rather than electrical or mechanical performance differences, as all specified parameters are identical.

Both parts carry ROHS3 compliance and REACH Affected designation, ensuring regulatory alignment for applications subject to these standards. The identical electrical ratings, thermal specifications, and physical dimensions guarantee direct interchangeability in chassis-mounted applications requiring 680 µF capacitance at 250 V with 2000-hour lifetime at 105°C.

Frequently Asked Questions (FAQ)

Q: Can LNT2E681MSE be used as a direct replacement for LNT2E681MSEN?

A: Yes. Both parts are identical across all electrical parameters (capacitance, voltage, tolerance, ripple current, lifetime), physical dimensions (lead spacing, diameter, height), mounting configuration (chassis mount with screw terminals), and compliance certifications (ROHS3, REACH). Direct substitution is appropriate for any application currently specified for the LNT2E681MSEN.

Q: Are there differences in the screw terminal configuration between these parts?

A: No. Both parts use identical Radial, Can - Screw Terminal packaging with 0.500" (12.70 mm) lead spacing. Physical installation and PCB layout requirements are identical.

Q: Do these parts have different thermal or lifetime ratings?

A: No. Both parts are rated for 2000 hours at 105°C and operate across the identical temperature range of -25°C to 105°C. Ripple current handling is identical at both 120 Hz (1.4 A) and 10 kHz (1.68 A).

Q: What is the difference between LNT2E681MSEN and LNT2E681MSE?

A: The parts are parametrically equivalent. The designation difference reflects internal Nichicon part numbering conventions but does not indicate functional or performance variation. Both are active products from the same LNT series.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both parts are ROHS3 Compliant and REACH Affected, meeting current regulatory requirements for electronic component manufacturing and use.
