SMG100VB33RM8X11LL Equivalent & Substitute Parts

Part Overview

The SMG100VB33RM8X11LL is a 33 µF, 100 V aluminum electrolytic capacitor in radial, can package manufactured by Chemi-Con. This component is classified as obsolete, indicating it is no longer in active production. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, making it suitable for general-purpose applications requiring stable capacitance performance in through-hole configurations.

Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for production and field service applications.

Engineering Selection Recommendations

Primary Recommendation: ESMG101ELL330MHB5D (Chemi-Con)

ESMG101ELL330MHB5D is the preferred substitute for SMG100VB33RM8X11LL. Both components are manufactured by Chemi-Con and belong to the SMG series. ESMG101ELL330MHB5D carries Active product status and is ROHS3 compliant, addressing the obsolescence and compliance limitations of the original part. The electrical parameters are identical, with only a minor height increase of 0.059" (1.50 mm), which is acceptable for most through-hole applications. Current inventory of 1095 pieces supports production requirements.

Secondary Recommendation: ECA-2AM330 (Panasonic Electronic Components)

ECA-2AM330 is an Active product with ROHS3 compliance from Panasonic Electronic Components. All critical electrical parameters match the original specification. Height is 0.492" (12.50 mm), representing a 0.039" (1.00 mm) increase. Ripple current at low frequency is reduced to 145 mA, which may require evaluation in ripple-sensitive applications. Inventory of 908 pieces is available.

Tertiary Recommendation: UVR2A330MPD (Nichicon)

UVR2A330MPD from Nichicon meets all critical electrical and mechanical parameters. Product status is Not For New Designs; however, it remains suitable for replacement and field service applications. ROHS3 compliance is confirmed. Height is 0.512" (13.00 mm). Ripple current at high frequency is 360 mA @ 10 kHz, exceeding the original specification. Highest inventory availability at 5978 pieces supports sustained supply.

Not Recommended for New Designs: UFW2A330MPD and UKW2A330MPD

Both Nichicon parts carry Not For New Designs status. UFW2A330MPD and UKW2A330MPD are electrically compatible but should be reserved for field replacement and legacy system maintenance only. Both are ROHS3 compliant with identical height to the original part (0.453" / 11.50 mm).

Frequently Asked Questions (FAQ)

Q1: Can ESMG101ELL330MHB5D be used as a direct replacement for SMG100VB33RM8X11LL?

A: Yes. ESMG101ELL330MHB5D is electrically and mechanically compatible. Both parts share identical capacitance (33 µF), voltage rating (100 V), tolerance (±20%), operating temperature range (-40°C to 85°C), and lifetime (2000 Hrs @ 85°C). The height difference of 0.059" (1.50 mm) is within acceptable mechanical envelope tolerances for through-hole PCB applications. ESMG101ELL330MHB5D is Active and ROHS3 compliant, addressing the obsolescence of the original part.

Q2: What is the significance of the height variation among substitute parts?

A: Height variations range from 0.453" (11.50 mm) to 0.512" (13.00 mm). These differences must be evaluated against PCB clearance requirements, enclosure height constraints, and component density in the assembly. Parts with greater height (ESMG101ELL330MHB5D, ECA-2AM330, UVR2A330MPD) require verification of vertical clearance. Parts matching the original height (UFW2A330MPD, UKW2A330MPD) present no height-related compatibility concerns.

Q3: Why do some substitute parts show different ripple current ratings?

A: Ripple current specifications vary by manufacturer design and series. ECA-2AM330 shows reduced ripple current (145 mA @ 120 Hz, 246.5 mA @ 10 kHz) compared to the original (180 mA @ 120 Hz, 324 mA @ 100 kHz). Applications with high ripple current demands must confirm that substitute ripple ratings are adequate. UVR2A330MPD exceeds original ripple current specifications, providing additional margin in ripple-sensitive circuits.

Q4: What does "Not For New Designs" product status mean?

A: "Not For New Designs" indicates the manufacturer has discontinued active development and marketing of the part but continues to supply existing inventory. These parts are suitable for field replacement, legacy system maintenance, and repair applications. For new product development, Active status parts (ESMG101ELL330MHB5D, ECA-2AM330) are preferred to ensure long-term availability and manufacturer support.

Q5: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The original SMG100VB33RM8X11LL is RoHS non-compliant. If the application requires RoHS compliance for regulatory or customer requirements, any of the listed substitutes satisfy this requirement.

Q6: Which substitute part has the highest inventory availability?

A: UVR2A330MPD from Nichicon has the highest current inventory at 5978 pieces. ESMG101ELL330MHB5D (Chemi-Con) has 1095 pieces, and ECA-2AM330 (Panasonic) has 908 pieces. For applications requiring large production quantities, UVR2A330MPD provides the most immediate supply assurance.

Q7: Can UFW2A330MPD and UKW2A330MPD be used interchangeably?

A: Yes. UFW2A330MPD and UKW2A330MPD are cross-referenced as substitutes for each other. Both are Nichicon products with identical electrical specifications, height (0.453" / 11.50 mm), and Not For New Designs status. Selection between them depends on availability and application-specific requirements. Both are ROHS3 compliant.

Q8: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by exact matching of: capacitance (33 µF), voltage rating (100 V), tolerance (±20%), operating temperature range (-40°C to 85°C), lifetime (2000 Hrs @ 85°C), polarization (Polar), mounting type (Through Hole), package type (Radial, Can), lead spacing (0.138" / 3.50 mm), and case diameter (0.315" / 8.00 mm). Height variations are acceptable within mechanical envelope constraints. ESR and ripple current variations are acceptable unless specified as critical design parameters.
