SMG450VB101M22DLL Equivalent & Substitute Parts

Part Overview

The SMG450VB101M22DLL is a 100 µF, 450 V aluminum electrolytic capacitor manufactured by Chemi-Con in a radial, through-hole configuration. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The part operates across a temperature range of -25°C to 85°C with a rated lifetime of 2000 hours at 85°C, making it suitable for general-purpose applications requiring stable capacitance and voltage performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMG450VB101M22DLL is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 100 µF
• Voltage Rating: 450 V
• Tolerance: ±20%
• Mounting Type: Through Hole
• Package Type: Radial, Can
• Lead Spacing: 0.394" (10.00 mm)
• Diameter: 0.866" (22.00 mm)
• Operating Temperature Range: -25°C to 85°C
• Lifetime @ Temperature: 2000 Hrs @ 85°C
• Polarization: Polar

The substitute part UVR2W101MRD from Nichicon meets all mandatory matching parameters and is therefore classified as a direct equivalent for the SMG450VB101M22DLL. Both components share identical electrical specifications and mechanical footprints, enabling direct board-level substitution without design modification.

Parameter Comparison

Engineering Selection Recommendations

The UVR2W101MRD from Nichicon is a direct functional equivalent to the SMG450VB101M22DLL. Both components are classified as obsolete products, indicating limited availability through standard distribution channels. The primary distinction between these parts is regulatory compliance: the UVR2W101MRD achieves ROHS3 compliance, whereas the SMG450VB101M22DLL is RoHS non-compliant.

The UVR2W101MRD presents a 2.00 mm height differential (42.00 mm versus 40.00 mm seated height), which remains within typical PCB layout tolerances for radial through-hole capacitors and does not preclude direct substitution in standard applications.

Selection between these equivalents should be based on regulatory requirements applicable to the end application and component availability through procurement channels.

Frequently Asked Questions (FAQ)

Q: Can the UVR2W101MRD directly replace the SMG450VB101M22DLL on a PCB?

A: Yes. Both components share identical lead spacing (0.394" / 10.00 mm), diameter (0.866" / 22.00 mm), and electrical specifications (100 µF, 450 V, ±20% tolerance). The height difference of 2.00 mm does not prevent direct board-level substitution in standard through-hole applications.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching capacitance (100 µF), voltage rating (450 V), tolerance (±20%), lead spacing (0.394" / 10.00 mm), diameter (0.866" / 22.00 mm), operating temperature range (-25°C to 85°C), lifetime rating (2000 Hrs @ 85°C), mounting type (through hole), and package configuration (radial, can).

Q: Why is the RoHS compliance status different between these parts?

A: The SMG450VB101M22DLL predates RoHS3 compliance requirements and is classified as non-compliant. The UVR2W101MRD achieves ROHS3 compliance, making it suitable for applications subject to current regulatory standards.

Q: Are there any electrical performance differences between these capacitors?

A: Both components meet identical electrical specifications for capacitance, voltage rating, tolerance, operating temperature range, and lifetime. The SMG450VB101M22DLL specifies ESR of 86 mOhm @ 120 Hz and ripple current ratings; the UVR2W101MRD does not provide ESR specification but specifies ripple current @ 120 Hz as 350 mA.

Q: What inventory status should be considered for procurement?

A: The SMG450VB101M22DLL has 1019 pieces in stock, while the UVR2W101MRD has 5152 pieces in stock. Both are classified as obsolete products, indicating that current inventory represents the available supply.
