LDM2G101MERYGA Equivalent & Substitute Parts

Part Overview

The LDM2G101MERYGA is a 100 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling in through-hole configurations. The part is currently active in production. Equivalent and substitute parts may be required due to inventory constraints, supply chain considerations, or specific application requirements where alternative manufacturers' components meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LDM2G101MERYGA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 100 µF (exact match required)
• Rated voltage: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Lead spacing: 0.295" (7.50mm) (exact match required)
• Operating temperature range: -25°C ~ 85°C (minimum requirement)
• Lifetime rating: 2000 Hrs @ 85°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (required for regulated applications)

The ECA-2GM101 manufactured by Panasonic Electronic Components meets all critical electrical parameters and compliance requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The ECA-2GM101 is electrically equivalent to the LDM2G101MERYGA across all critical parameters: capacitance, voltage rating, tolerance, temperature range, and lifetime rating. Both components are ROHS3 compliant and suitable for general-purpose applications. The ECA-2GM101 is classified as obsolete, whereas the LDM2G101MERYGA maintains active production status. Selection between these parts should prioritize the LDM2G101MERYGA for new designs and ongoing production due to its active availability. The ECA-2GM101 may be selected only when the LDM2G101MERYGA is unavailable and existing inventory of the Panasonic part is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the ECA-2GM101 be used as a direct replacement for the LDM2G101MERYGA?

A: Yes. Both components share identical electrical specifications: 100 µF capacitance, 400 V rated voltage, ±20% tolerance, 2000 Hrs @ 85°C lifetime, and -25°C ~ 85°C operating temperature range. Both are ROHS3 compliant and mounted through-hole with 0.295" (7.50mm) lead spacing in radial can packages.

Q: Are there physical dimension differences between these parts?

A: Yes. The LDM2G101MERYGA has a diameter of 0.787" (20.00mm) and height of 1.260" (32.00mm). The ECA-2GM101 has a diameter of 0.709" (18.00mm) and height of 1.654" (42.00mm). PCB layout and enclosure clearances must accommodate these dimensional variations.

Q: What is the difference in ripple current ratings?

A: The LDM2G101MERYGA is rated for 900 mA @ 120 Hz and 1.287 A @ 50 kHz. The ECA-2GM101 is rated for 600 mA @ 120 Hz and 1.02 A @ 10 kHz. Applications requiring high ripple current handling should prioritize the LDM2G101MERYGA.

Q: Why is the ECA-2GM101 listed as obsolete?

A: The ECA-2GM101 has been discontinued by Panasonic Electronic Components. The LDM2G101MERYGA remains in active production and is the recommended choice for new designs and ongoing supply requirements.

Q: Are both parts suitable for my application?

A: Substitution is valid only when the application requirements do not exceed the lower ripple current specifications of the ECA-2GM101 and when physical dimensions can be accommodated within the PCB layout and enclosure design.
