Equivalent & Substitute Parts for LGJ2D151MELZ

Part Overview

The LGJ2D151MELZ is a 150 µF, 200 V aluminum electrolytic capacitor manufactured by Nichicon in the LGJ series. This radial, can-style snap-in capacitor is designed for general-purpose applications with a rated lifetime of 3000 hours at 105°C and an operating temperature range of -40°C to 105°C. The part is currently active and ROHS3 compliant. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits selection from qualified alternatives meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGJ2D151MELZ is determined by strict equivalence across the following parameters: capacitance value (150 µF), rated voltage (200 V), tolerance (±20%), polarization (polar), package type (radial, can - snap-in), mounting method (through hole), and lead spacing (10.00 mm). All identified substitutes meet these core electrical and mechanical requirements. Variations in lifetime rating, ripple current specifications, physical dimensions, and ESR values are documented but do not disqualify parts from substitution eligibility when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are active products with ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the LGJ2D151MELZ. Selection among these alternatives depends on specific application constraints:

The LGJ2D151MELZ and B43254A2157M000 share identical physical dimensions (0.866" diameter, 0.866" height) and both provide 3000-hour lifetime ratings at 105°C, making them direct mechanical and thermal equivalents for space-constrained applications.

The LGJ2D151MELA15, also from Nichicon, offers the same electrical specifications but with a larger diameter (0.984") and reduced height (0.669"), providing a footprint alternative when vertical space is limited. The 2000-hour lifetime rating is lower than the primary part.

The LP151M200C1P3 from Cornell Dubilier Electronics provides electrical equivalence with the largest physical footprint (0.984" diameter, 0.984" height) and the shortest lifetime rating (1000 hours at 105°C). This part includes documented ESR specification (1.65 Ohm @ 120 Hz) and MSL rating (1 - Unlimited).

Frequently Asked Questions (FAQ)

Q: Can LGJ2D151MELA15 be used as a direct replacement for LGJ2D151MELZ?

A: LGJ2D151MELA15 meets all core electrical requirements (150 µF, 200 V, ±20% tolerance, polar, radial snap-in, 10.00 mm lead spacing, through-hole mounting). Physical dimensions differ: the substitute is larger in diameter (25.00 mm vs. 22.00 mm) but shorter in height (17.00 mm vs. 22.00 mm). Lifetime rating is reduced from 3000 hours to 2000 hours at 105°C. Substitution is valid when PCB layout accommodates the larger diameter and reduced lifetime is acceptable for the application.

Q: What are the key differences between B43254A2157M000 and LGJ2D151MELZ?

A: Both parts share identical physical dimensions (22.00 mm diameter and height), identical electrical specifications (150 µF, 200 V, ±20%), and identical lifetime ratings (3000 hours at 105°C). The primary difference is manufacturer: EPCOS - TDK Electronics versus Nichicon. Both are ROHS3 compliant and active products. Ripple current specifications differ slightly across frequency ranges but both parts meet the same electrical class.

Q: Is LP151M200C1P3 suitable for applications requiring extended lifetime?

A: LP151M200C1P3 provides 1000-hour lifetime at 105°C, which is significantly lower than the LGJ2D151MELZ (3000 hours). This part is electrically equivalent but thermally rated for shorter service life. Selection of LP151M200C1P3 is appropriate only when application duty cycles and thermal conditions do not require extended lifetime performance.

Q: Are all substitute parts available in the same packaging format?

A: All identified substitutes are supplied in bulk packaging as radial, can-style snap-in capacitors with through-hole mounting and 10.00 mm lead spacing. Physical dimensions vary as documented in the parameter comparison table. All parts are suitable for standard PCB assembly processes compatible with through-hole radial capacitor mounting.

Q: What compliance certifications apply to all substitute parts?

A: All parts listed—LGJ2D151MELZ, LGJ2D151MELA15, LP151M200C1P3, and B43254A2157M000—are ROHS3 compliant and REACH unaffected. ECCN classification is EAR99 for all parts, and HTSUS code is 8532.22.0040. Moisture sensitivity level is not applicable for LGJ series parts; LP151M200C1P3 carries MSL rating 1 (Unlimited).
