LP123M025H3P3 Equivalent & Substitute Parts

Part Overview

The LP123M025H3P3 is a 12000 µF, 25 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 high capacitance in a compact through-hole form factor. The part is ROHS3 compliant and REACH unaffected, making it suitable for modern electronic equipment.

Substitute parts become necessary when the primary component experiences extended lead times, inventory constraints, or when design requirements permit operation at higher voltage ratings while maintaining identical capacitance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP123M025H3P3 is based on strict electrical and mechanical parameter alignment. The following criteria determine valid substitutes:

Mandatory Matching Parameters:

• Capacitance: 12000 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Diameter: 1.378" (35.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Permissible Variation Parameters:

• Voltage Rating: Substitute must equal or exceed 25 V
• Operating Temperature Range: Substitute must support -40°C to 105°C minimum
• Height: Substitute may vary within mechanical envelope constraints
• Lifetime @ Temperature: Substitute may exceed specified hours
• ESR and Ripple Current: Substitute specifications may differ if not specified as critical design constraints

The LGY1V123MELC30 manufactured by Nichicon meets all mandatory matching criteria and exceeds the voltage rating requirement, making it a valid direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The LGY1V123MELC30 is a direct substitute for the LP123M025H3P3 based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters align exactly. The substitute's 35 V rating exceeds the 25 V requirement, providing additional voltage margin without affecting circuit operation. Both components maintain identical capacitance (12000 µF) and tolerance (±20%), ensuring equivalent energy storage and circuit behavior.

Mechanical Compatibility: Both components share identical lead spacing (10.00mm), diameter (35.00mm), and mounting type (through-hole, snap-in). The substitute's maximum seated height of 1.260" (32.00mm) exceeds the original part's 1.181" (30.00mm) by 2.00mm. This height difference must be evaluated against available PCB clearance in the target application.

Regulatory and Compliance Status: Both parts are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. Both maintain Active product status with established supply chains.

Operational Performance: Both components support the full operating temperature range of -40°C to 105°C. The substitute's lifetime specification of 5000 hours at 105°C exceeds the original part's 1000 hours, indicating enhanced reliability under thermal stress.

Frequently Asked Questions (FAQ)

Q: Can the LGY1V123MELC30 be used as a direct replacement for the LP123M025H3P3 in all applications?

A: The LGY1V123MELC30 is electrically and mechanically compatible with the LP123M025H3P3 for applications where the 2.00mm height difference does not create PCB clearance conflicts. Verify available vertical space in the target assembly before substitution.

Q: Why does the substitute part have a higher voltage rating (35 V vs. 25 V)?

A: Higher voltage ratings do not negatively impact circuit operation when the applied voltage remains at or below the original specification. The 35 V rating provides additional safety margin and is a common characteristic of substitute components from different manufacturers.

Q: Are the lead spacings identical between these two parts?

A: Yes. Both the LP123M025H3P3 and LGY1V123MELC30 have lead spacing of 0.394" (10.00mm), ensuring identical PCB footprint compatibility.

Q: What is the significance of the height difference between these parts?

A: The LGY1V123MELC30 has a maximum seated height of 1.260" (32.00mm) compared to the LP123M025H3P3 at 1.181" (30.00mm). This 2.00mm difference must be evaluated against available clearance above the component on the PCB assembly, including any overlying components or enclosure constraints.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the LP123M025H3P3 and LGY1V123MELC30 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for modern electronic equipment.

Q: What is the difference in lifetime specifications between these parts?

A: The LP123M025H3P3 specifies 1000 hours at 105°C, while the LGY1V123MELC30 specifies 5000 hours at 105°C. The substitute's extended lifetime indicates superior thermal stability and reliability under sustained elevated temperature operation.

Q: Are the capacitance and tolerance values identical?

A: Yes. Both parts are rated at 12000 µF with ±20% tolerance, ensuring identical energy storage capacity and circuit performance characteristics.

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

A: Both parts support comparable ripple current specifications at 120 Hz (2.97 A for the original, 2.9 A for the substitute). Ripple current performance at higher frequencies differs slightly; verify the substitute's ripple current specification against your specific application frequency requirements.
