LDM2D471MERZGA Equivalent & Substitute Parts

Part Overview

The LDM2D471MERZGA 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 maintains active product status with full ROHS3 compliance and REACH unaffected certification.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility permits selection from compatible alternatives within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the LDM2D471MERZGA is determined by strict equivalence across the following parameters:

Capacitance value: 470 µF (exact match required)
Voltage rating: 200 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime specification: 2000 Hrs @ 85°C (exact match required)
Operating temperature range: -40°C ~ 85°C (exact match required)
Polarization: Polar (exact match required)
Mounting type: Through Hole (exact match required)
Package configuration: Radial, Can (exact match required)
Compliance certifications: ROHS3 Compliant, REACH Unaffected (exact match required)

The identified substitute parts UVK2D471MRD and UVR2D471MRD6 meet all core electrical and mechanical requirements. Variations in lead spacing, case diameter, and height do not affect functional equivalence within through-hole PCB designs that accommodate standard component placement tolerances.

Engineering Selection Recommendations

LDM2D471MERZGA (Primary Selection)

The LDM2D471MERZGA maintains active product status with current manufacturing and full availability. This part is the preferred selection for new designs and ongoing production requirements. Active status ensures long-term supply chain stability and consistent manufacturing quality.

UVK2D471MRD (Secondary Selection)

The UVK2D471MRD is electrically and mechanically equivalent with obsolete product status. This part is suitable for legacy system maintenance, repair, and field replacement where existing PCB layouts accommodate the 0.394" (10.00mm) lead spacing and 1.654" (42.00mm) height. Inventory availability is confirmed at 1102 pieces.

UVR2D471MRD6 (Tertiary Selection)

The UVR2D471MRD6 is electrically and mechanically equivalent with obsolete product status. This part is suitable for legacy system maintenance where PCB designs accommodate the 0.492" (12.50mm) lead spacing and 0.984" (25.00mm) case diameter. Inventory availability is confirmed at 1024 pieces.

All three parts carry identical ROHS3 compliance and REACH unaffected certifications, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can UVK2D471MRD or UVR2D471MRD6 be used as direct replacements for LDM2D471MERZGA?

A: Yes, both parts are electrically equivalent. However, PCB layout compatibility must be verified. The lead spacing differs: LDM2D471MERZGA uses 0.335" (8.50mm), UVK2D471MRD uses 0.394" (10.00mm), and UVR2D471MRD6 uses 0.492" (12.50mm). Existing through-hole pad patterns must accommodate these spacing variations.

Q: What is the difference between the three parts?

A: All three parts share identical electrical specifications: 470 µF capacitance, 200 V rating, ±20% tolerance, 2000 hours lifetime at 85°C, and -40°C to 85°C operating range. Physical differences include lead spacing, case diameter, and height. The LDM2D471MERZGA is the only active product; UVK2D471MRD and UVR2D471MRD6 are obsolete.

Q: Why are UVK2D471MRD and UVR2D471MRD6 marked as obsolete?

A: Obsolete status indicates these series are no longer in active production. However, existing inventory remains available for purchase. These parts are suitable for legacy equipment repair and maintenance where supply from active product lines is not feasible.

Q: Are there any ripple current differences between these parts?

A: Yes. The LDM2D471MERZGA specifies 1.88 A @ 120 Hz and 2.82 A @ 50 kHz. The UVK2D471MRD specifies 1.3 A @ 120 Hz and 1.495 A @ 10 kHz. The UVR2D471MRD6 specifies 1.55 A @ 120 Hz and 1.7825 A @ 10 kHz. Applications requiring specific ripple current performance must reference the exact part datasheet.

Q: Can these parts be used interchangeably in new product designs?

A: New designs should use the LDM2D471MERZGA due to its active product status and guaranteed long-term availability. Substitutes are appropriate only when the primary part is unavailable and PCB layout permits physical accommodation of alternative lead spacing and dimensions.
