SMG100VB2R2M5X11LL Equivalent & Substitute Parts

Part Overview

The SMG100VB2R2M5X11LL is a 2.2 µF, 100 V aluminum electrolytic capacitor in radial, can package manufactured by Chemi-Con. This component is classified as obsolete and operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C. The part is designed for general-purpose applications requiring polar capacitive energy storage and filtering in through-hole mounted configurations.

Due to its obsolete product status, locating replacement units from original inventory becomes increasingly difficult. Equivalent and substitute parts from active manufacturers or alternative series provide functional continuity for repair, redesign, and production applications while maintaining electrical and mechanical compatibility within specified parameters.

Engineering Selection Recommendations

For Active Production and New Designs:

The ECA-2AM2R2 (Panasonic Electronic Components) and SK2R2M100ST (Cornell Dubilier Electronics) are recommended as primary substitutes. Both parts maintain active product status, ensuring long-term availability and supply chain continuity. Both are ROHS3 compliant, meeting current environmental and regulatory requirements for commercial and industrial applications. The ECA-2AM2R2 offers 5896 units in current inventory, providing substantial stock availability. The SK2R2M100ST provides 1022 units with lower ESR (48.25 mOhm @ 120 Hz) compared to the original specification (106 mOhm @ 120 Hz), delivering improved performance characteristics in filtering and energy storage applications.

For Legacy System Repair and Maintenance:

The ESMG101ELL2R2ME11D (Chemi-Con) represents a direct manufacturer upgrade within the same product family. This part maintains Chemi-Con manufacturing heritage while achieving active product status and ROHS3 compliance. Height increase from 0.433" to 0.492" (11.00 mm to 12.50 mm) requires PCB layout verification but remains within acceptable mechanical envelope for most through-hole applications. Inventory of 1128 units supports repair operations.

For Extended Temperature Applications:

The UPW2A2R2MDD (Nichicon) provides enhanced thermal performance with 2000 hours lifetime at 105°C and extended operating range of -55°C to 105°C. This upgrade is suitable for applications requiring higher temperature stability. Note that ripple current specifications are reduced (13.2 mA @ 120 Hz, 44 mA @ 100 kHz) compared to the original part; application requirements must be verified before selection.

For Direct Form Factor Matching:

The UKW2A2R2MDD (Nichicon) and UVR2A2R2MDD (Nichicon) maintain identical height (0.433" / 11.00 mm and 0.492" / 12.50 mm respectively) and lead spacing as the original part, minimizing PCB layout modifications. Both are ROHS3 compliant; however, both carry obsolete product status, limiting future availability.

All recommended substitutes maintain the critical electrical parameters: 2.2 µF capacitance, 100 V voltage rating, ±20% tolerance, polar configuration, and through-hole radial can package with 0.079" (2.00 mm) lead spacing and 0.197" (5.00 mm) diameter.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than 100 V?

A: Yes. Higher voltage ratings (e.g., 160 V, 250 V) are electrically compatible and provide additional safety margin. However, physical dimensions may increase, requiring PCB layout verification. All listed substitutes maintain the 100 V rating to ensure form factor compatibility.

Q: What is the significance of ESR (Equivalent Series Resistance) in capacitor substitution?

A: ESR affects ripple current handling, heat generation, and filtering performance. Lower ESR values indicate better high-frequency performance. The original SMG100VB2R2M5X11LL specifies 106 mOhm @ 120 Hz. The SK2R2M100ST provides 48.25 mOhm @ 120 Hz, representing improved performance. Substitutes with higher ESR values are acceptable if application ripple current requirements are met.

Q: Does the height difference between substitute parts affect PCB compatibility?

A: Yes. The original part height is 0.433" (11.00 mm). Substitutes range from 0.433" to 0.512" (11.00 mm to 13.00 mm). Height increases require verification that PCB clearance, component spacing, and mechanical constraints are satisfied. Taller components may interfere with adjacent components or enclosure geometry.

Q: Why is RoHS compliance important for substitute selection?

A: ROHS3 compliance indicates the part meets current environmental regulations restricting hazardous substances (lead, cadmium, mercury, hexavalent chromium, PBBs, PBDEs). For new production, ROHS3 compliant parts are mandatory in most markets. The original SMG100VB2R2M5X11LL is RoHS non-compliant; all active substitutes (ESMG101ELL2R2ME11D, ECA-2AM2R2, SK2R2M100ST) are ROHS3 compliant.

Q: What does "obsolete product status" mean for the original part?

A: Obsolete status indicates the manufacturer has discontinued production. The SMG100VB2R2M5X11LL is no longer manufactured by Chemi-Con. Current inventory (887 units) represents remaining stock; once depleted, the part becomes unavailable. Substitutes with active status ensure continued availability for future production runs and repairs.

Q: Can I substitute a part with different ripple current specifications?

A: Ripple current specifications must meet or exceed application requirements. The original part specifies 30 mA @ 120 Hz and 75 mA @ 100 kHz. Substitutes with equal or higher ripple current ratings are directly compatible. Substitutes with lower ripple current ratings (e.g., UPW2A2R2MDD: 13.2 mA @ 120 Hz) require application verification to ensure adequate performance.

Q: Are all listed substitutes mechanically interchangeable?

A: All substitutes maintain identical lead spacing (0.079" / 2.00 mm) and diameter (0.197" / 5.00 mm), ensuring PCB footprint compatibility. Height variations (0.433" to 0.512" / 11.00 mm to 13.00 mm) require clearance verification. All are through-hole radial can packages with polar configuration.

Q: What is the difference between "Similar" and "Direct" substitute classifications?

A: "Similar" substitutes meet all critical electrical and mechanical parameters but may originate from different manufacturers or series. "Direct" substitutes are from the same manufacturer family. "Upgrade" substitutes provide enhanced performance (e.g., higher temperature rating). All classifications in this reference maintain functional equivalence for the specified application parameters.
