159LMB025M2ED Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The 159LMB025M2ED is a 15000 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the LMB series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high capacitance in a compact through-hole package. The part is Active status and ROHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific performance parameters necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the 159LMB025M2ED are qualified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Capacitance: 15000 µF (exact match required)
• Voltage Rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Size / Dimension: 1.378" Dia (35.00mm) (exact match required)
• Height - Seated (Max): 1.260" (32.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Compatible Operating Parameters:

• Operating Temperature Range: -40°C ~ 105°C (all substitutes match)
• RoHS Status: ROHS3 Compliant (all substitutes comply)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part number in applications designed for the 159LMB025M2ED.

Parameter Comparison

Engineering Selection Recommendations

All three parts are Active status components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component sourcing.

159LMB025M2ED (Main Part): Baseline reference with 3000 hours lifetime at 105°C and ESR of 49.7359 mOhm @ 120Hz. Suitable for standard general-purpose applications.

LGY1E153MELC30 (Nichicon): Offers extended lifetime of 5000 hours at 105°C, providing enhanced reliability margin for long-term operation. Lower ripple current specification at 120 Hz (2.9 A) compared to main part. Appropriate for applications requiring extended service life.

381LX153M025A022 (Cornell Dubilier Electronics): Maintains 3000 hours lifetime matching the main part. Highest ripple current capability at 120 Hz (3.6 A) and 20 kHz (4.1 A), suitable for applications with elevated ripple current demands. Same manufacturer family as main part.

Selection between substitutes depends on application-specific requirements for lifetime duration and ripple current handling capacity, with all parts maintaining identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can LGY1E153MELC30 be used as a direct replacement for 159LMB025M2ED?

A: Yes. Both parts share identical capacitance (15000 µF), voltage rating (25 V), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (0.394" / 10.00mm), physical dimensions (1.378" Dia / 35.00mm), height (1.260" / 32.00mm), mounting type (Through Hole), and operating temperature range (-40°C ~ 105°C). The LGY1E153MELC30 provides extended lifetime (5000 Hrs @ 105°C versus 3000 Hrs), making it a compatible upgrade.

Q: Can 381LX153M025A022 be used as a direct replacement for 159LMB025M2ED?

A: Yes. Both parts share identical capacitance (15000 µF), voltage rating (25 V), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (0.394" / 10.00mm), physical dimensions (1.378" Dia / 35.00mm), height (1.260" / 32.00mm), mounting type (Through Hole), and operating temperature range (-40°C ~ 105°C). The 381LX153M025A022 maintains equivalent lifetime (3000 Hrs @ 105°C) and offers higher ripple current capability.

Q: What are the critical parameters that must match for substitution?

A: Capacitance, voltage rating, tolerance, package type, lead spacing, physical dimensions, height, mounting type, and polarization must all match exactly. All three parts meet these requirements.

Q: Are there differences in ripple current handling between these parts?

A: Yes. At 120 Hz: 159LMB025M2ED provides 3.25 A, LGY1E153MELC30 provides 2.9 A, and 381LX153M025A022 provides 3.6 A. Applications with specific ripple current requirements should reference these values.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with identical HTSUS code 8532.22.0040.

Q: What is the difference in lifetime specifications?

A: 159LMB025M2ED and 381LX153M025A022 both specify 3000 hours at 105°C. LGY1E153MELC30 specifies 5000 hours at 105°C, providing extended operational life for demanding applications.

Q: Are these parts suitable for snap-in mounting applications?

A: Yes. All three parts feature Radial, Can - Snap-In package type with identical lead spacing (0.394" / 10.00mm) and dimensions, confirming compatibility with snap-in mounting hardware and PCB layouts designed for this package style.
