LP151M200A1P3 Equivalent & Substitute Parts

Part Overview

The LP151M200A1P3 is a 150 µF, 200 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is actively produced and suitable for general-purpose applications requiring through-hole mounting. Alternative equivalent parts are necessary to address inventory availability, extended lifetime requirements, and design optimization across different thermal and ripple current specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP151M200A1P3 are qualified based on strict electrical and mechanical compatibility criteria. All equivalent parts maintain identical capacitance (150 µF), voltage rating (200 V), and tolerance (±20%). All substitute parts share the same operating temperature range (-40°C ~ 105°C), through-hole radial snap-in package configuration, and lead spacing (0.394"/10.00mm). The primary differentiator among qualified substitutes is thermal lifetime at 105°C, which ranges from 1000 hours to 3000 hours depending on the specific part series. Ripple current ratings vary across the substitutes due to different core designs and internal resistance characteristics. All substitute parts are ROHS3 compliant and maintain unrestricted moisture sensitivity.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are actively produced and ROHS3 compliant, satisfying regulatory requirements for current applications. Selection between equivalent parts depends on application-specific thermal lifetime requirements and ripple current specifications.

The LP151M200A1P3 and LP151M200C1P3 are functionally identical CDE units; the primary difference is packaging (tube versus bulk) and case diameter. These parts are appropriate for applications with standard thermal expectations of 1000 hours at 105°C.

The B43252A2157M000 (EPCOS - TDK Electronics) offers doubled thermal lifetime (2000 hours at 105°C) with increased ripple current capacity (630 mA @ 120 Hz, 976.5 mA @ 20 kHz) in a compact 0.866" diameter footprint. This part is suitable for applications requiring extended operational lifespan or higher ripple current specifications.

The B43254A2157M000 provides the highest thermal lifetime (3000 hours at 105°C) with identical ripple current performance to the B43252A2157M000, in the same compact footprint. This part is recommended for demanding thermal or extended-life applications.

Frequently Asked Questions (FAQ)

Q: Can LP151M200C1P3 be used as a direct replacement for LP151M200A1P3?

A: Yes. Both parts are identical in electrical specifications (150 µF, 200 V, ±20% tolerance, 1000 Hrs @ 105°C) and operate across the same temperature range. The difference is case diameter (0.984" versus 0.866") and packaging format. Verify physical space availability in your PCB layout.

Q: What is the primary difference between the CDE and EPCOS - TDK Electronics parts?

A: The EPCOS - TDK Electronics B43252A2157M000 and B43254A2157M000 offer extended thermal lifetimes (2000 Hrs and 3000 Hrs respectively, compared to 1000 Hrs for CDE parts) and higher ripple current ratings. All parts maintain identical capacitance, voltage rating, tolerance, and operating temperature range.

Q: Which part should be selected for high-ripple-current applications?

A: The B43252A2157M000 or B43254A2157M000 (EPCOS - TDK Electronics) both provide 630 mA ripple current at 120 Hz and 976.5 mA at 20 kHz, compared to 509 mA and 712.6 mA respectively for the CDE parts. These EPCOS parts are suited for circuits with higher ripple current demands.

Q: Are all substitute parts through-hole mounted?

A: Yes. All four parts use radial, snap-in through-hole mounting with 0.394" (10.00mm) lead spacing, ensuring compatibility with standard PCB footprints designed for radial aluminum electrolytic capacitors in this package class.

Q: What compliance certifications apply to these parts?

A: All four parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity is MSL 1 (unlimited) across all parts, indicating no moisture-sensitive device precautions are required during handling or storage.
