ULD2G2R7MPD Equivalent & Substitute Parts

Part Overview

The Nichicon ULD2G2R7MPD is a 2.7 µF, 400 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product lineup. The ULD series capacitor is rated for 15000 hours at 105°C and is suitable for general purpose applications requiring polar electrolytic capacitors with through-hole mounting.

Finding equivalent or substitute parts is necessary when the original ULD2G2R7MPD is unavailable or when design flexibility permits selection from active product lines that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ULD2G2R7MPD is determined by strict equivalence across the following critical parameters:

• Capacitance value: 2.7 µF (exact match required)
• Voltage rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 15000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Lead spacing: 0.138" (4.60mm) (exact match required)
• Diameter: 0.315" Dia (8.00mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)

All substitute parts listed below meet these criteria. Height variations within the radial can package are permissible provided they do not exceed the maximum seated height of 0.531" (14.60mm) for the original part or create mechanical interference in the target application.

Engineering Selection Recommendations

Primary Selection (Active Product Status):

The 400LLE2R7MEFC8X11.5 (Rubycon) is the preferred substitute. This part carries Active product status, indicating ongoing manufacturer support and availability. It matches all critical electrical parameters including capacitance, voltage rating, tolerance, lifetime specification, and operating temperature range. The maximum seated height of 0.531" (14.60mm) is identical to the original ULD2G2R7MPD, ensuring direct mechanical compatibility. High-frequency ripple current specification (86 mA @ 100 kHz) is provided, matching the original part's performance envelope.

Secondary Selection (Direct Manufacturer Equivalent):

The 400LLE2.7MEFC8X11.5 (Rubycon) is a direct manufacturer equivalent with Active product status. All electrical parameters are identical to the primary selection. The maximum seated height is 0.512" (13.00mm), which is 0.019" shorter than the original part. This reduced height provides additional clearance margin in space-constrained applications. High-frequency ripple current data is not specified for this variant.

Alternative Selection (Parametric Equivalent):

The 400LLE2.7MEFC8X11R5 (Rubycon) meets all electrical and mechanical specifications but carries Not For New Designs status, matching the original ULD2G2R7MPD classification. This part is suitable only when inventory constraints or application-specific requirements necessitate its use. Maximum seated height is 0.512" (13.00mm).

All substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, maintaining regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can I substitute the ULD2G2R7MPD with any of the listed Rubycon parts?

A: Yes. All listed Rubycon parts (400LLE2.7MEFC8X11.5, 400LLE2.7MEFC8X11R5, and 400LLE2R7MEFC8X11.5) meet the complete electrical and mechanical specification set of the original Nichicon ULD2G2R7MPD. Substitution is valid from an engineering standpoint provided the application does not impose additional constraints beyond the specified parameters.

Q: What is the difference between the three Rubycon substitutes?

A: The three Rubycon parts differ in product status and height specification. The 400LLE2R7MEFC8X11.5 and 400LLE2.7MEFC8X11.5 are Active products with ongoing manufacturer support. The 400LLE2.7MEFC8X11R5 is Not For New Designs. The 400LLE2R7MEFC8X11.5 and 400LLE2.7MEFC8X11R5 have a maximum seated height of 0.512" (13.00mm), while the 400LLE2.7MEFC8X11.5 matches the original height of 0.531" (14.60mm).

Q: Does the height difference between parts affect compatibility?

A: Height differences within the specified range do not affect electrical compatibility. The 0.019" height reduction in the 400LLE2.7MEFC8X11.5 and 400LLE2.7MEFC8X11R5 variants provides additional clearance in the vertical direction. Verify that the target PCB layout and enclosure design accommodate the original maximum height of 0.531" (14.60mm) to ensure all variants fit without modification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status, matching the original ULD2G2R7MPD. Regulatory compliance is maintained across all substitution options.

Q: Which substitute should I select for new designs?

A: For new designs, select the 400LLE2R7MEFC8X11.5 (Rubycon). This part carries Active product status, indicating manufacturer commitment to ongoing production and support. It provides identical electrical performance and mechanical compatibility with the original specification.

Q: What is the lead spacing tolerance, and does it affect PCB layout?

A: The lead spacing is 0.138" (4.60mm) for all parts listed. This specification is fixed and identical across the original and all substitute parts. No PCB layout modification is required when substituting between these components.
