Equivalent & Substitute Parts for UAS2G101MHD

Part Overview

The UAS2G101MHD 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 through-hole mounting. The part is currently active in production and ROHS3 compliant.

Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements allow for alternative specifications that maintain functional compatibility within the application's electrical and mechanical constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UAS2G101MHD is determined by the following mandatory parameters:

Core Electrical Parameters:

• Capacitance: 100 µF (exact match required)
• Voltage Rating: 400 V minimum (equal or higher acceptable)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Core Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.295" (7.50mm) (exact match required)
• Size / Dimension: 0.709" Dia (18.00mm) (exact match required)

Environmental Parameters:

• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Substitute parts are classified into two categories: parametric equivalents (matching all core parameters) and upgrade parts (exceeding voltage or lifetime specifications while maintaining mechanical compatibility).

Parameter Comparison

Engineering Selection Recommendations

UVY2G101MHD (Parametric Equivalent): This part matches all core electrical and mechanical parameters of the UAS2G101MHD. However, the UVY2G101MHD carries a product status of "Not For New Designs," indicating it is in end-of-life phase. Selection of this substitute is appropriate only for legacy system maintenance, repair, or replacement applications where design continuity with existing inventory is required. For new designs, this part should not be selected.

450BXW100MEFR18X35 (Upgrade): This Rubycon part exceeds the voltage specification (450 V vs. 400 V) and provides significantly extended lifetime (12000 Hrs @ 105°C vs. 2000 Hrs @ 105°C). All mechanical parameters remain compatible. The part is currently active in production and ROHS3 compliant. This upgrade substitute is suitable for applications where enhanced reliability and extended operational life are beneficial, provided the circuit design accommodates the higher voltage rating. The height dimension is 0.019" shorter (1.457" vs. 1.476"), which remains within typical PCB layout tolerances for through-hole components.

Frequently Asked Questions (FAQ)

Q: Can UVY2G101MHD be used as a direct replacement for UAS2G101MHD?

A: UVY2G101MHD matches all core electrical and mechanical parameters and is mechanically and electrically compatible. However, its "Not For New Designs" status indicates end-of-life status. Use this substitute only for repair or legacy system applications.

Q: What is the advantage of using 450BXW100MEFR18X35 over the original UAS2G101MHD?

A: The 450BXW100MEFR18X35 provides a 50 V higher voltage rating (450 V vs. 400 V) and six times longer operational lifetime (12000 Hrs vs. 2000 Hrs at 105°C). All mechanical parameters remain compatible. This upgrade is beneficial for applications requiring extended reliability.

Q: Are there any height differences between these parts?

A: The UAS2G101MHD and UVY2G101MHD both have a maximum seated height of 1.476" (37.50mm). The 450BXW100MEFR18X35 has a maximum seated height of 1.457" (37.00mm), which is 0.019" shorter. This minor difference is typically accommodated within standard PCB layout tolerances for through-hole radial capacitors.

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

A: Yes. All three parts have identical lead spacing of 0.295" (7.50mm), ensuring direct PCB footprint compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. UAS2G101MHD, UVY2G101MHD, and 450BXW100MEFR18X35 are all ROHS3 compliant.

Q: What is the difference in ripple current handling between these parts?

A: Ripple current specifications differ across the three parts. UAS2G101MHD handles 490 mA @ 120 Hz and 784 mA @ 10 kHz. UVY2G101MHD handles 310 mA @ 120 Hz and 356.5 mA @ 10 kHz. 450BXW100MEFR18X35 handles 835 mA @ 120 Hz and 1.879 A @ 100 kHz. Selection should be based on the specific ripple current requirements of the application circuit.
