Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP221M250A3P3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 1000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Lead spacing: 0.394" (10.00mm) (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)

Compliance Parameters:

• RoHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)

The substitute part LP221M250E1P3 meets all electrical and mechanical equivalence criteria. Dimensional variations in can diameter and height do not affect substitution eligibility when lead spacing and mounting type remain constant for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both LP221M250A3P3 and LP221M250E1P3 are Active products manufactured by Cornell Dubilier Electronics and fully compliant with RoHS3 and REACH regulations. Selection between these parts is based on the following criteria:

LP221M250A3P3 is the primary specification when the original part number is required for design documentation, qualification records, or when inventory of this specific variant is available.

LP221M250E1P3 is an equivalent substitute when LP221M250A3P3 is unavailable. This part provides identical electrical performance with specified ESR characteristics (1.13 Ohm @ 120Hz) and ripple current ratings (710 mA @ 120 Hz; 994 mA @ 100 kHz). The dimensional difference (larger diameter, shorter height) must be evaluated against available PCB layout space and mechanical clearance requirements in the target application.

Both parts maintain identical lead spacing (10.00mm) and through-hole mounting compatibility, ensuring direct substitution at the circuit board level when physical space permits.

Frequently Asked Questions (FAQ)

Q: Can LP221M250E1P3 be used as a direct replacement for LP221M250A3P3?

A: Yes, LP221M250E1P3 is an electrical and functional equivalent. Both parts share identical capacitance (220 µF), voltage rating (250 V), tolerance (±20%), lifetime specification (1000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), lead spacing (10.00mm), and mounting type (through-hole radial snap-in). Physical dimensions differ; verify available PCB space before substitution.

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

A: Substitution requires exact equivalence in: capacitance value, voltage rating, tolerance, lifetime at temperature, operating temperature range, polarization, lead spacing, package type, and mounting method. RoHS3 compliance and MSL rating must also match.

Q: Does the dimensional difference between LP221M250A3P3 and LP221M250E1P3 affect electrical performance?

A: No. The dimensional difference (can diameter and height) does not affect electrical performance. Both parts deliver identical capacitance, voltage rating, and lifetime specifications. Dimensional evaluation is necessary only for mechanical fit and PCB layout compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both LP221M250A3P3 and LP221M250E1P3 are RoHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the lead spacing for these capacitors?

A: Both parts have a lead spacing of 0.394 inches (10.00mm), ensuring compatibility with standard through-hole PCB footprints designed for this spacing.

Q: Can these capacitors be used in high-ripple-current applications?

A: LP221M250E1P3 specifies ripple current ratings: 710 mA @ 120 Hz and 994 mA @ 100 kHz. LP221M250A3P3 does not provide ripple current specifications in the available data. For applications requiring defined ripple current performance, LP221M250E1P3 is the preferred selection.
