LDM2D471MERYGA Equivalent & Substitute Parts

Part Overview

The LDM2D471MERYGA is a 470 µF, 200 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 in active production status with ROHS3 compliance.

Equivalent and substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or design revisions require alternative lead spacing or physical dimensions while maintaining core electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LDM2D471MERYGA is determined by the following core parameters:

• Capacitance Value: 470 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime Rating: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)

The identified substitute parts UVK2D471MRD and UVR2D471MRD6 meet all core electrical and mechanical requirements. Variations in lead spacing and physical dimensions are permissible when PCB layout accommodates the alternative footprint.

Engineering Selection Recommendations

LDM2D471MERYGA is the preferred selection for new designs. This part maintains active production status, ensuring long-term availability and supply chain stability. ROHS3 compliance and REACH unaffected status confirm regulatory alignment for current manufacturing standards.

UVK2D471MRD and UVR2D471MRD6 are classified as obsolete products. These parts are suitable for legacy system maintenance, field replacements, or applications where existing PCB layouts accommodate the larger lead spacing and physical dimensions. Both parts maintain ROHS3 compliance and identical electrical specifications to the primary part.

Selection between UVK2D471MRD and UVR2D471MRD6 depends on PCB footprint compatibility. UVK2D471MRD features 10.00mm lead spacing with 22.00mm diameter, while UVR2D471MRD6 features 12.50mm lead spacing with 25.00mm diameter. Both share identical height of 42.00mm.

Frequently Asked Questions (FAQ)

Q: Can UVK2D471MRD or UVR2D471MRD6 be used as direct replacements for LDM2D471MERYGA?

A: Electrical substitution is valid. All three parts share identical capacitance (470 µF), voltage rating (200 V), tolerance (±20%), and lifetime rating (2000 Hrs @ 85°C). Physical substitution requires PCB layout verification due to different lead spacing: LDM uses 7.50mm, UVK uses 10.00mm, and UVR uses 12.50mm spacing.

Q: Why are UVK2D471MRD and UVR2D471MRD6 marked as obsolete?

A: Obsolete status indicates these product lines have been discontinued by Nichicon. Existing inventory remains available, but no new production is scheduled. For new designs, LDM2D471MERYGA is the recommended active alternative.

Q: Are there differences in ripple current handling between these parts?

A: Yes. LDM2D471MERYGA handles 1.93 A at 120 Hz and 2.895 A at 50 kHz. UVK2D471MRD handles 1.3 A at 120 Hz and 1.495 A at 10 kHz. UVR2D471MRD6 handles 1.55 A at 120 Hz and 1.7825 A at 10 kHz. Application ripple current requirements must be verified against the selected part's specifications.

Q: Do all three parts meet current compliance requirements?

A: Yes. All parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and distribution.

Q: What is the primary consideration when choosing between substitute parts?

A: PCB footprint compatibility is the primary consideration. Lead spacing and can diameter differ across the three parts. Verify that the selected part's physical dimensions fit the existing PCB layout before implementation.
