LP122M063A1P3 Equivalent & Substitute Parts

Part Overview

The LP122M063A1P3 is a 1200 µF, 63 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is designed for general-purpose applications requiring through-hole mounting with a rated lifetime of 1000 hours at 105°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across critical parameters including capacitance, voltage rating, tolerance, operating temperature range, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both LP122M063A1P3 and LP122M063C1P3 are active production components manufactured by Cornell Dubilier Electronics with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is based on availability and packaging format:

LP122M063A1P3: Primary part number with 806 units in current inventory stock.

LP122M063C1P3: Direct substitute with 1828 units in current inventory stock. This part provides higher availability and includes documented ESR specification (210 mOhm @ 120Hz) and ripple current ratings (990 mA @ 120 Hz, 1.188 A @ 100 kHz), which may be beneficial for applications requiring detailed electrical characterization.

Both parts satisfy identical electrical performance requirements and mechanical form factor specifications. Selection should be based on inventory availability and application-specific ripple current or ESR requirements.

Frequently Asked Questions (FAQ)

Q: Can LP122M063C1P3 be used as a direct replacement for LP122M063A1P3?

A: Yes. Both parts are manufactured by Cornell Dubilier Electronics with identical capacitance (1200 µF), voltage rating (63 V), tolerance (±20%), operating temperature range (-40°C to 105°C), lifetime specification (1000 Hrs @ 105°C), lead spacing (10.00mm), and package type (Radial, Can - Snap-In). All critical electrical and mechanical parameters match exactly.

Q: What are the physical differences between these parts?

A: The LP122M063C1P3 has a larger diameter (0.984" vs. 0.866") but maintains the same height (0.984") and identical lead spacing (10.00mm). Both use through-hole mounting with snap-in can packages. PCB layout compatibility depends on available space for the larger diameter component.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8532.22.0040.

Q: Which part should be selected for new designs?

A: Selection should be based on PCB layout constraints and inventory availability. The LP122M063C1P3 offers higher stock availability (1828 units vs. 806 units) and includes documented ESR and ripple current specifications, which may be advantageous for applications requiring detailed electrical performance data.

Q: Are these parts interchangeable in existing assemblies?

A: Interchangeability depends on available PCB space. The LP122M063C1P3 has a larger diameter (0.984" vs. 0.866") and may not fit in layouts designed for the LP122M063A1P3. Lead spacing and mounting type are identical, so electrical connections remain compatible if physical space permits.
