LPX821M160C5P3 Equivalent & Substitute Parts

Part Overview

The LPX821M160C5P3 is a 820 µF, 160 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active and is designed for general-purpose applications requiring through-hole mounting. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 1000 hours at 85°C.

Substitute parts are identified when equivalent capacitance and tolerance values are maintained while accommodating variations in voltage rating, thermal performance, ripple current handling, and operating temperature range. Alternative components may be required due to inventory availability, enhanced thermal specifications, or improved ripple current performance in demanding applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPX821M160C5P3 is determined by the following criteria:

Primary Matching Parameters:

• Capacitance: 820 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Physical Dimensions: 25.00 mm diameter, 35.00 mm height (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Substitute parts rated at 200 V are acceptable as they exceed the 160 V requirement
• Operating Temperature Range: Substitute parts with extended upper temperature limits (-40°C ~ 105°C) are acceptable
• Lifetime @ Temperature: Substitute parts with extended lifetime specifications are acceptable
• Ripple Current: Substitute parts with equal or greater ripple current ratings are acceptable
• ESR: Variations in ESR are acceptable provided electrical performance requirements are met

Compliance Requirements:

• RoHS3 Compliance: Required
• REACH Status: REACH Unaffected required

Two substitute parts meet these criteria: LAR2D821MELA35 (Nichicon) and LLS2D821MELA (Nichicon).

Parameter Comparison

Engineering Selection Recommendations

Both identified substitute parts are Active products with full RoHS3 compliance and REACH Unaffected status, meeting regulatory requirements equivalent to the LPX821M160C5P3.

LAR2D821MELA35 (Nichicon LAR Series): This substitute provides a 200 V rated voltage, exceeding the 160 V requirement of the original part. The operating temperature range extends to 105°C, and the lifetime specification is 2000 hours at 105°C. Ripple current at 120 Hz is 2.04 A, marginally exceeding the original 2 A specification. However, ripple current at 50 kHz is 1.36 A, which is lower than the original 2.2 A. This substitute is suitable for applications where low-frequency ripple current dominates and extended high-temperature operation is not required.

LLS2D821MELA (Nichicon LLS Series): This substitute provides a 200 V rated voltage and maintains the -40°C ~ 85°C operating temperature range of the original part. The lifetime specification is 3000 hours at 85°C, representing a threefold improvement over the original 1000 hours. Ripple current performance is superior at both frequencies: 2.79 A at 120 Hz and 4.185 A at 50 kHz, both exceeding the original specifications. This substitute is suitable for applications requiring extended component lifetime and higher ripple current handling capacity.

Frequently Asked Questions (FAQ)

Q: Can LAR2D821MELA35 be used as a direct replacement for LPX821M160C5P3?

A: Yes. Both parts share identical capacitance (820 µF), tolerance (±20%), package type (Radial, Can - Snap-In), physical dimensions (25.00 mm diameter, 35.00 mm height), and lead spacing (10.00 mm). The LAR2D821MELA35 has a higher voltage rating (200 V vs. 160 V), which is acceptable for direct substitution. However, the ripple current at 50 kHz is lower (1.36 A vs. 2.2 A), which may be a limiting factor in high-frequency applications.

Q: Can LLS2D821MELA be used as a direct replacement for LPX821M160C5P3?

A: Yes. Both parts share identical capacitance (820 µF), tolerance (±20%), package type (Radial, Can - Snap-In), physical dimensions (25.00 mm diameter, 35.00 mm height), lead spacing (10.00 mm), and operating temperature range (-40°C ~ 85°C). The LLS2D821MELA has a higher voltage rating (200 V vs. 160 V) and superior ripple current performance at both 120 Hz and 50 kHz, making it suitable for direct substitution in all applications.

Q: What is the primary difference between the two substitute parts?

A: LAR2D821MELA35 extends the operating temperature range to 105°C and provides 2000 hours lifetime at that temperature, making it suitable for high-temperature environments. LLS2D821MELA maintains the original -40°C ~ 85°C temperature range but offers 3000 hours lifetime at 85°C and superior ripple current handling at both low and high frequencies. Selection depends on whether extended high-temperature operation or enhanced ripple current performance is required.

Q: Are all three parts (LPX821M160C5P3, LAR2D821MELA35, and LLS2D821MELA) mechanically interchangeable?

A: Yes. All three parts have identical physical dimensions (25.00 mm diameter, 35.00 mm height), lead spacing (10.00 mm), and package type (Radial, Can - Snap-In). They are mechanically interchangeable on through-hole PCB layouts designed for 10.00 mm lead spacing.

Q: Do the substitute parts meet the same regulatory compliance as the original?

A: Yes. Both LAR2D821MELA35 and LLS2D821MELA are RoHS3 Compliant and REACH Unaffected, matching the compliance status of the LPX821M160C5P3.

Q: Which substitute part should be selected for maximum component lifetime?

A: LLS2D821MELA provides the longest lifetime specification at 3000 hours at 85°C, compared to 1000 hours for the original LPX821M160C5P3 and 2000 hours at 105°C for LAR2D821MELA35.

Q: Which substitute part has better ripple current performance?

A: LLS2D821MELA has superior ripple current performance at both specified frequencies: 2.79 A at 120 Hz (vs. 2 A original) and 4.185 A at 50 kHz (vs. 2.2 A original). LAR2D821MELA35 has comparable performance at 120 Hz (2.04 A) but lower performance at 50 kHz (1.36 A).
