Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LLS2A272MELB are qualified based on the following criteria:

• Identical capacitance value: 2700 µF
• Identical tolerance: ±20%
• Identical rated voltage: 100 V
• Identical lifetime specification: 3000 Hrs @ 85°C
• Identical operating temperature range: -40°C ~ 85°C
• Identical polarization: Polar
• Identical package type: Radial, Can - Snap-In
• Identical mounting type: Through Hole
• Identical lead spacing: 0.394" (10.00mm)
• ROHS3 compliance maintained

Variations in physical dimensions (diameter and height) and ripple current ratings are permitted within the snap-in package category, as these do not affect electrical equivalence or board-level compatibility when lead spacing and mounting type remain constant.

Engineering Selection Recommendations

All three parts—LLS2A272MELB, LLS2A272MELC, and 380LX272M100J452—meet the core electrical and mechanical requirements for direct substitution. Selection among these parts should be based on:

• Physical space constraints: The 380LX272M100J452 has the smallest diameter (25.00mm) but greatest height (47.00mm). The LLS2A272MELB offers mid-range dimensions (30.00mm diameter, 37.00mm height). The LLS2A272MELC has the largest diameter (35.00mm) but shortest height (32.00mm).
• Inventory availability and lead time requirements.
• Compliance requirements: All parts maintain ROHS3 compliance and REACH unaffected status.
• Product status: All parts are Active and suitable for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can LLS2A272MELC replace LLS2A272MELB directly on the PCB?

A: Yes. Both parts share identical electrical specifications (2700 µF, 100 V, ±20%, 3000 Hrs @ 85°C) and mechanical compatibility (10.00mm lead spacing, through-hole radial snap-in package). Physical dimensions differ, but the snap-in mounting type accommodates these variations.

Q: Is the 380LX272M100J452 from Cornell Dubilier Electronics electrically equivalent?

A: Yes. The 380LX272M100J452 meets all core electrical parameters: 2700 µF capacitance, 100 V rating, ±20% tolerance, 3000 Hrs @ 85°C lifetime, and -40°C ~ 85°C operating range. Lead spacing and mounting type are identical. Physical dimensions differ but remain compatible with snap-in package specifications.

Q: What is the significance of different physical dimensions among these parts?

A: Physical dimensions (diameter and height) vary due to different internal construction methods used by manufacturers. These variations do not affect electrical performance or board-level compatibility when lead spacing (10.00mm) and mounting type (through-hole radial snap-in) remain constant. Verify available PCB space before selection.

Q: Are ripple current differences significant for substitution?

A: Ripple current values provided indicate the current-handling capability at specified frequencies. Variations among these parts (3.65 A to 3.77 A @ 120 Hz) fall within normal manufacturing tolerances for this capacitor category and do not prevent substitution. Select based on your circuit's actual ripple current requirements.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Compliance status is maintained across all substitutes.
