Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLPX221M350A5P3 are classified based on strict alignment with the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance: 220 µF
• Voltage Rating: 350 V
• Tolerance: ±20%
• Polarization: Polar

Mechanical Parameters (Must Match):

• Package Type: Radial, Can - Snap-In
• Lead Spacing: 0.394" (10.00mm)
• Size / Dimension: 0.866" Dia (22.00mm)
• Height - Seated (Max): 1.457" (37.00mm)
• Mounting Type: Through Hole

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Two substitute parts meet these criteria:

1. LGN2V221MELZ35 (Nichicon) - Upgrade substitute with extended operating temperature range (-25°C ~ 105°C) and higher temperature lifetime rating (3000 Hrs @ 105°C)

2. LLS2V221MELZ (Nichicon) - Parametric equivalent with identical operating temperature range (-25°C ~ 85°C) and matching lifetime rating (3000 Hrs @ 85°C)

Parameter Comparison

Engineering Selection Recommendations

LGN2V221MELZ35 (Nichicon) - Upgrade Substitute:

This part is suitable for applications requiring extended thermal performance. The operating temperature range extends to 105°C with a lifetime rating of 3000 hours at that elevated temperature, compared to the main part's 85°C maximum. All electrical and mechanical parameters remain equivalent. Both parts maintain ROHS3 compliance and REACH unaffected status. Selection of this substitute is appropriate when circuit designs operate in higher ambient temperature environments or when thermal margin is a design consideration.

LLS2V221MELZ (Nichicon) - Parametric Equivalent:

This part provides direct parametric equivalence to the SLPX221M350A5P3. Operating temperature range, lifetime rating, and ripple current specifications at 120 Hz are identical. All mechanical dimensions and mounting characteristics match exactly. Both parts maintain ROHS3 compliance and REACH unaffected status. Selection of this substitute is appropriate for direct replacement in existing designs without thermal or performance modifications.

Frequently Asked Questions (FAQ)

Q: Can LGN2V221MELZ35 be used as a direct replacement for SLPX221M350A5P3?

A: Yes. The LGN2V221MELZ35 meets all electrical and mechanical substitution criteria. It provides identical capacitance (220 µF), voltage rating (350 V), tolerance (±20%), package type (Radial, Can - Snap-In), and physical dimensions. The extended operating temperature range to 105°C represents an enhancement rather than a limitation.

Q: Can LLS2V221MELZ be used as a direct replacement for SLPX221M350A5P3?

A: Yes. The LLS2V221MELZ is a parametric equivalent with identical electrical specifications, operating temperature range (-25°C ~ 85°C), lifetime rating (3000 Hrs @ 85°C), and mechanical dimensions. All mounting and compliance characteristics are equivalent.

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

A: The primary difference is operating temperature capability. LGN2V221MELZ35 operates to 105°C with a 3000-hour lifetime at that temperature, while LLS2V221MELZ operates to 85°C with a 3000-hour lifetime at that temperature. Both are electrically and mechanically equivalent to the main part at standard operating conditions.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both LGN2V221MELZ35 and LLS2V221MELZ are ROHS3 compliant and REACH unaffected, matching the compliance status of the SLPX221M350A5P3.

Q: Do the substitute parts have the same physical footprint?

A: Yes. Both substitute parts have identical lead spacing (0.394" / 10.00mm), diameter (0.866" / 22.00mm), and maximum seated height (1.457" / 37.00mm). They are compatible with the same through-hole mounting locations.

Q: What is the ripple current difference between the main part and LGN2V221MELZ35?

A: At 120 Hz, the SLPX221M350A5P3 supports 1.47 A ripple current, while LGN2V221MELZ35 supports 1 A. This difference reflects the thermal design of each part. Circuit designs must verify ripple current requirements against the selected substitute.
