LDQ2D471MERZGA Equivalent & Substitute Parts

Part Overview

The LDQ2D471MERZGA is a 470 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is currently in active production status. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative configurations with compatible electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the LDQ2D471MERZGA are qualified based on the following criteria:

Electrical Parameters: Capacitance (470 µF), voltage rating (200 V), and tolerance (±20%) must be identical
Operating Conditions: Temperature range (-40°C ~ 105°C) and polarization (Polar) must match
Mechanical Compatibility: Through-hole mounting and radial can package configuration must be maintained
Compliance: RoHS3 compliance and REACH unaffected status must be preserved

The substitute parts UPS2D471MRD and UVY2D471MRD meet these core electrical and mechanical requirements. Variations in lead spacing, physical dimensions, and lifetime ratings are secondary parameters that may affect board layout and reliability expectations but do not prevent functional substitution when electrical specifications align.

Engineering Selection Recommendations

LDQ2D471MERZGA is the primary selection for new designs. This part maintains active production status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

UPS2D471MRD is a secondary option when supply of the primary part is constrained. This substitute offers extended lifetime (3000 hours at 105°C versus 2000 hours), which may provide enhanced reliability in applications with demanding thermal profiles. However, this part is obsolete and inventory is limited. Lead spacing differs (10.00mm versus 8.50mm), requiring PCB layout verification before implementation.

UVY2D471MRD is a tertiary option with equivalent lifetime rating (2000 hours at 105°C) to the primary part. This substitute is also obsolete with limited inventory. Lead spacing is identical to UPS2D471MRD (10.00mm), and physical height (42.00mm) falls between the primary part and UPS2D471MRD, potentially offering a compromise for space-constrained applications. PCB layout verification is required due to lead spacing differences.

All three parts are manufactured by Nichicon and maintain identical electrical specifications (470 µF, 200 V, ±20% tolerance). Selection should prioritize the active-status primary part for new production. Substitutes are appropriate only when supply constraints necessitate alternative sourcing and PCB layout accommodates the dimensional variations.

Frequently Asked Questions (FAQ)

Q: Can UPS2D471MRD or UVY2D471MRD be used as direct replacements for LDQ2D471MERZGA?

A: Electrical substitution is valid. Both parts share identical capacitance (470 µF), voltage rating (200 V), tolerance (±20%), and operating temperature range (-40°C ~ 105°C). However, lead spacing differs (10.00mm versus 8.50mm), requiring PCB layout modification. Physical height also varies, which may affect mechanical clearance in confined spaces.

Q: What is the impact of the different lead spacing?

A: Lead spacing affects PCB hole pattern and component placement. The primary part LDQ2D471MERZGA uses 8.50mm spacing, while both substitutes use 10.00mm spacing. This difference requires PCB redesign or manual lead bending, which is not recommended for production environments.

Q: Why are UPS2D471MRD and UVY2D471MRD marked as obsolete?

A: Obsolete status indicates these parts are no longer in active production. Inventory is limited and future availability cannot be guaranteed. These parts should be considered only as temporary solutions when the active primary part is unavailable.

Q: Does the extended lifetime of UPS2D471MRD (3000 hours versus 2000 hours) provide a performance advantage?

A: Extended lifetime indicates longer operational capability under thermal stress at 105°C. In applications with sustained elevated temperatures, this may provide enhanced reliability. However, this advantage must be weighed against obsolete status and limited inventory.

Q: Are all three parts RoHS3 compliant and REACH unaffected?

A: Yes. LDQ2D471MERZGA, UPS2D471MRD, and UVY2D471MRD are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What ripple current differences exist between these parts?

A: Ripple current ratings vary across the three parts at different frequencies. The primary part LDQ2D471MERZGA is rated for 1.45 A at 120 Hz and 2.175 A at 50 kHz. UPS2D471MRD provides 1.31 A at 120 Hz and 1.5065 A at 10 kHz. UVY2D471MRD provides 925 mA at 120 Hz and 1.06375 A at 10 kHz. Application-specific ripple current requirements must be verified before substitution.
