Substitute Part Grouping Explanation

Substitution of the LNT1C684MSEN is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 680000 µF (exact match required)
• Rated voltage: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package type: Radial, Can - Screw Terminals (exact match required)
• Mounting configuration: Chassis Mount (exact match required)
• Physical dimensions: 4.643" Dia (90.00mm), 6.811" (173.00mm) height, 1.252" (31.80mm) lead spacing (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Lifetime rating: 2000 Hrs @ 105°C (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The LNT1C684MSE meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the LNT1C684MSEN and LNT1C684MSE are Active status components manufactured by Nichicon and carry ROHS3 compliance certification. Selection between these parts is based on inventory availability and application-specific ripple current requirements at 10 kHz operation. The LNT1C684MSEN provides 36 A ripple current capacity at 10 kHz, while the LNT1C684MSE provides 21.16 A at the same frequency. Both parts maintain identical electrical and mechanical specifications across all other parameters, including capacitance, voltage rating, tolerance, operating temperature range, and physical dimensions. Component selection should account for the specific ripple current demands of the target application circuit.

Frequently Asked Questions (FAQ)

Q: Can LNT1C684MSE be used as a direct replacement for LNT1C684MSEN?

A: Yes. Both parts are parametric equivalents with identical capacitance (680000 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-40°C ~ 105°C), lifetime rating (2000 Hrs @ 105°C), physical dimensions, lead spacing, and package configuration (Radial, Can - Screw Terminals). Both are ROHS3 compliant and Active status. The ripple current specification at 10 kHz differs between the two parts; verify this parameter against your circuit requirements before selection.

Q: What are the critical parameters for substitution?

A: Substitution requires exact matching of capacitance value, rated voltage, tolerance, polarization type, package style, mounting configuration, physical dimensions, lead spacing, operating temperature range, and lifetime rating. Any deviation in these parameters disqualifies a part from being a direct equivalent.

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

A: No. Both LNT1C684MSEN and LNT1C684MSE carry identical ROHS3 compliance status, REACH affected designation, and EAR99 ECCN classification.

Q: What is the significance of the ripple current difference at 10 kHz?

A: Ripple current rating indicates the maximum AC current the capacitor can handle at a specified frequency without exceeding temperature limits. The LNT1C684MSEN is rated for 36 A at 10 kHz, while the LNT1C684MSE is rated for 21.16 A at 10 kHz. Applications with high-frequency ripple current demands should use the part with the appropriate ripple current rating for the operating conditions.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts use identical Radial, Can - Screw Terminals packaging with chassis mount configuration, identical lead spacing (1.252" / 31.80mm), and identical physical dimensions (4.643" diameter, 6.811" maximum seated height).
