LLS2E471MELZ Equivalent & Substitute Parts

Part Overview

The LLS2E471MELZ is a 470 µF, 250 V aluminum electrolytic capacitor manufactured by Nichicon in the LLS series. This radial, can-style snap-in component is rated for 3000 hours at 85°C and operates across -40°C to 85°C. The part is Active status and ROHS3 compliant, designed for general-purpose applications requiring stable capacitance and ripple current handling in through-hole configurations.

Substitute parts are necessary when the primary part is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits equivalent electrical and mechanical performance from alternative manufacturers while maintaining the same functional specifications.

Substitute Part Grouping Explanation

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

Electrical Equivalence: Capacitance (470 µF), voltage rating (250 V), and tolerance (±20%) must match exactly
Thermal Performance: Lifetime rating of 3000 hours at 85°C or greater
Operating Range: Temperature range must encompass or equal -40°C to 85°C
Mechanical Compatibility: Radial, can-style snap-in package with 0.394" (10.00mm) lead spacing and through-hole mounting
Compliance: ROHS3 or equivalent RoHS compliance required

All four substitute parts meet these core criteria. Variations in physical dimensions (diameter and height) are acceptable provided the snap-in package type and lead spacing remain constant, as these allow component placement within standard PCB footprints designed for radial snap-in capacitors.

Engineering Selection Recommendations

All four substitute parts are Active status components with appropriate compliance certifications. Selection among these equivalents should be based on:

LLS2E471MELB (Nichicon): Same manufacturer as the primary part with identical electrical specifications and ROHS3 compliance. Physical dimensions differ (1.181" diameter, 0.984" height versus 0.866" diameter, 1.378" height), requiring PCB layout verification for clearance.

380LX471M250J042 (Cornell Dubilier Electronics): Meets all electrical and thermal requirements with ROHS3 compliance. ESR specification of 39 mOhm at 120 Hz is provided. Physical dimensions (0.984" diameter, 1.654" height) differ from the main part and require layout confirmation.

ESMQ251VSN471MP35S (Chemi-Con): Meets core electrical specifications with RoHS compliance. Lifetime rating is 2000 hours at 85°C, which is lower than the 3000-hour rating of the main part and other substitutes. Operating temperature minimum is -25°C versus -40°C for the main part. Physical dimensions match the main part (0.866" diameter, 1.378" height).

SLPX471M250E1P3 (Cornell Dubilier Electronics): Meets all electrical and thermal requirements with ROHS3 compliance. ESR specification of 423 mOhm at 120 Hz is provided. Physical dimensions (1.181" diameter, 0.984" height) differ from the main part and require layout confirmation.

Frequently Asked Questions (FAQ)

Q: Can I use ESMQ251VSN471MP35S as a direct replacement for LLS2E471MELZ?

A: ESMQ251VSN471MP35S meets the core electrical specifications (470 µF, 250 V, ±20% tolerance) and physical package requirements. However, it has a 2000-hour lifetime at 85°C compared to 3000 hours for the main part, and its operating temperature minimum is -25°C rather than -40°C. Use this part only if your application does not require the extended thermal life or full temperature range.

Q: Do physical dimension differences affect PCB compatibility?

A: All substitute parts maintain the same lead spacing (0.394" / 10.00mm) and snap-in package type, ensuring electrical connection compatibility. However, diameter and height variations may affect physical clearance on the PCB. Verify that the substitute part's dimensions fit within the available space on your board layout.

Q: Are all substitutes ROHS3 compliant?

A: Four of the five parts (LLS2E471MELZ, LLS2E471MELB, 380LX471M250J042, and SLPX471M250E1P3) are ROHS3 compliant. ESMQ251VSN471MP35S is RoHS compliant but not specifically ROHS3 certified. Verify compliance requirements for your application.

Q: What is the significance of ESR values provided for some parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat generation. 380LX471M250J042 specifies 39 mOhm at 120 Hz, while SLPX471M250E1P3 specifies 423 mOhm at 120 Hz. Lower ESR generally indicates better high-frequency performance. Select based on your circuit's ripple current requirements.

Q: Can I interchange parts with different physical dimensions?

A: Physical dimensions differ among substitutes while maintaining the same lead spacing and snap-in package type. Interchange is electrically valid, but PCB layout must accommodate the substitute part's diameter and height. Verify clearance with surrounding components before substitution.
