Electrical Parameters:

• Capacitance: 220 µF (exact match required)
• Voltage Rating: 420 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -25°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Diameter: 0.866" (22.00mm) (exact match required)
• Height: 1.850" (47.00mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part 381LQ221M420H452 meets all critical electrical, mechanical, and compliance requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the PL2S221MND2245 and 381LQ221M420H452 are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. The parts are electrically and mechanically equivalent across all specified parameters.

The 381LQ221M420H452 (Cornell Dubilier Electronics) provides documented ESR and ripple current specifications at 120 Hz, offering additional performance transparency. The CDE part demonstrates higher ripple current capability (1.05 A versus 880 mA at 120 Hz), which may provide operational margin in applications with elevated AC ripple content.

Selection between these parts is based on availability, lead time, cost, and manufacturer preference. Both parts satisfy identical functional requirements for 220 µF, 420 V general-purpose aluminum electrolytic capacitor applications with through-hole snap-in mounting.

Frequently Asked Questions (FAQ)

Q: Can the 381LQ221M420H452 be used as a direct replacement for the PL2S221MND2245?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (220 µF), voltage rating (420 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-25°C ~ 105°C), package type (radial, can snap-in), mounting type (through hole), lead spacing (10.00mm), physical dimensions (22.00mm diameter, 47.00mm height), and compliance certifications (ROHS3, MSL 1).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact matching of capacitance, voltage rating, tolerance, lifetime at temperature, operating temperature range, polarization, package type, mounting type, lead spacing, physical dimensions, and compliance status. Deviation in any of these parameters disqualifies a part from direct substitution.

Q: Are there differences in performance between these two parts?

A: The 381LQ221M420H452 provides specified ESR (830 mOhm @ 120 Hz) and higher ripple current rating (1.05 A @ 120 Hz) compared to the PL2S221MND2245 ripple current specification (880 mA @ 120 Hz). These differences represent performance characteristics of the respective manufacturers and do not affect functional equivalence for general-purpose applications.

Q: Do both parts have the same physical footprint?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00mm), diameter (0.866" / 22.00mm), and maximum seated height (1.850" / 47.00mm). They are mechanically interchangeable on PCBs designed for either part.

Q: Are both parts RoHS compliant?

A: Yes. Both the PL2S221MND2245 and 381LQ221M420H452 are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1) ratings.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for general-purpose applications requiring 220 µF capacitance at 420 V with 2000-hour lifetime at 105°C operating temperature. Typical applications include power supply filtering, energy storage, and AC ripple suppression in industrial and commercial equipment.
