Equivalent & Substitute Parts for LDQ2G101MERYGA

Part Overview

The LDQ2G101MERYGA is a 100 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring reliable energy storage and filtering in power supply circuits. The part is currently active in production. Substitute parts may be required due to inventory availability, extended operational lifetime requirements, or specific mechanical constraints in board layout.

Substitute Part Grouping Explanation

Substitution eligibility for the LDQ2G101MERYGA is determined by strict equivalence across the following parameters:

Capacitance: 100 µF (exact match required)
Voltage Rating: 400 V (exact match required)
Tolerance: ±20% (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 7.50 mm (exact match required)
Polarization: Polar (exact match required)
Operating Temperature Range: -25°C to 105°C (exact match required)
RoHS Compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these core electrical and mechanical criteria. Variations in lifetime rating, ripple current specifications, and physical dimensions (diameter and height) are secondary parameters that do not disqualify substitution but may influence selection based on application-specific requirements.

Engineering Selection Recommendations

LDQ2G101MERYGA (Primary Part): Active product status with current manufacturing support. Suitable for applications where 2000-hour lifetime at 105°C meets design requirements.

UPT2G101MHD and UPT2G101MHD6: Both are active Nichicon products with extended 5000-hour lifetime at 105°C. These parts provide improved reliability margin over the primary part. Physical dimensions differ slightly; UPT2G101MHD6 (18.00 mm diameter, 33.00 mm height) offers closer dimensional compatibility to the original part compared to UPT2G101MHD (16.00 mm diameter, 37.00 mm height). Selection between these two should be based on available board space.

EEU-EE2G101: Panasonic product with 10000-hour lifetime at 105°C, offering the longest operational life. Product status is obsolete; use only when extended lifetime is critical and availability can be confirmed. Physical height (42.00 mm) is the largest among all options.

All substitute parts maintain ROHS3 compliance and identical electrical specifications for capacitance, voltage, and tolerance.

Frequently Asked Questions (FAQ)

Q: Can UPT2G101MHD or UPT2G101MHD6 be used as direct replacements for LDQ2G101MERYGA?

A: Yes. Both parts meet all core electrical and mechanical substitution criteria: 100 µF capacitance, 400 V rating, ±20% tolerance, 7.50 mm lead spacing, through-hole radial can package, and identical operating temperature range. The extended 5000-hour lifetime provides additional reliability margin.

Q: What is the difference between UPT2G101MHD and UPT2G101MHD6?

A: Both parts are electrically identical with 5000-hour lifetime at 105°C. The primary difference is physical dimension: UPT2G101MHD has 16.00 mm diameter and 37.00 mm height, while UPT2G101MHD6 has 18.00 mm diameter and 33.00 mm height. Selection depends on available board space and mounting constraints.

Q: Why is EEU-EE2G101 marked as obsolete?

A: The EEU-EE2G101 is no longer in active production by Panasonic. It remains electrically equivalent and functionally interchangeable but should only be selected if extended 10000-hour lifetime is essential and inventory availability can be confirmed through your supplier.

Q: Are there any ripple current differences I should consider?

A: Yes. The LDQ2G101MERYGA supports 700 mA at 120 Hz and 1.001 A at 50 kHz. The UPT series parts support 580 mA at 120 Hz and 928 mA at 10 kHz. The EEU-EE2G101 supports 824 mA at 120 Hz and 2.06 A at 100 kHz. Verify that the selected substitute meets your application's ripple current requirements at the operating frequency.

Q: Do all substitute parts have the same lead spacing?

A: Yes. All parts, including the primary LDQ2G101MERYGA and all substitutes, have 7.50 mm lead spacing, ensuring compatibility with existing PCB footprints.

Q: Are all parts RoHS compliant?

A: Yes. The LDQ2G101MERYGA and all substitute parts are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
