Substitute Part Grouping Explanation

Substitution for the SMG10VB331M6X11LL is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Lead Spacing: 0.098" (2.50mm) (exact match required)
• Diameter: 0.248" (6.30mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)

Secondary Considerations:

• Height variation within mechanical tolerance
• Ripple current ratings (may vary by manufacturer)
• RoHS compliance status
• Product status (active vs. obsolete)

All substitute parts listed below meet the primary substitution criteria and are mechanically and electrically compatible with the SMG10VB331M6X11LL.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Requirement: When sourcing for new designs or long-term production support, ESMG100ELL331MF11D (Chemi-Con) and ECA-1AM331 (Panasonic) are active products. Both maintain identical electrical specifications to the SMG10VB331M6X11LL and offer superior supply chain availability.

For RoHS3 Compliance: All substitute parts except the original SMG10VB331M6X11LL carry ROHS3 compliance certification. This is relevant for applications subject to RoHS directives. ESMG100ELL331MF11D, ECA-1AM331, UFW1A331MED, UKW1A331MED, and UVR1A331MED all meet this requirement.

For Mechanical Fit Considerations: Height variation exists among substitutes. The original SMG10VB331M6X11LL and Nichicon parts (UFW1A331MED, UKW1A331MED) share identical height of 0.433" (11.00mm). Chemi-Con ESMG100ELL331MF11D and Nichicon UVR1A331MED are taller at 0.492" (12.50mm). Panasonic ECA-1AM331 is 0.480" (12.20mm). Verify PCB layout clearance before selection.

For Ripple Current Performance: Panasonic ECA-1AM331 offers the highest ripple current ratings (330 mA @ 120 Hz, 561 mA @ 10 kHz), providing additional margin in high-ripple applications. Nichicon UFW1A331MED and UKW1A331MED provide lower ripple current (270 mA @ 120 Hz, 405 mA @ 10 kHz) and are suitable for general-purpose applications matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can I use ESMG100ELL331MF11D as a direct replacement for SMG10VB331M6X11LL?

A: Yes. ESMG100ELL331MF11D meets all primary substitution criteria: 330 µF capacitance, 10 V rating, ±20% tolerance, 2000 Hrs @ 85°C lifetime, identical lead spacing and diameter, and through-hole radial package. The height difference (0.492" vs. 0.433") must be verified against PCB layout clearance. ESMG100ELL331MF11D is an active product with ROHS3 compliance.

Q: What is the difference between the Nichicon UFW1A331MED and UKW1A331MED?

A: Both parts are electrically and mechanically identical: 330 µF, 10 V, ±20% tolerance, 2000 Hrs @ 85°C, identical dimensions and lead spacing. Both are obsolete Nichicon products with ROHS3 compliance. Selection between them depends on inventory availability and application-specific requirements.

Q: Why does ECA-1AM331 have higher ripple current ratings?

A: Ripple current capability is a manufacturer-specific design characteristic. ECA-1AM331 (Panasonic) is rated for 330 mA @ 120 Hz and 561 mA @ 10 kHz, compared to the original 290 mA @ 120 Hz and 435 mA @ 100 kHz. This reflects different internal construction and materials. Higher ripple current does not affect compatibility; it indicates additional performance margin in ripple-intensive applications.

Q: Are all substitute parts RoHS compliant?

A: No. The original SMG10VB331M6X11LL is RoHS non-compliant. All five substitute parts (ESMG100ELL331MF11D, UFW1A331MED, UKW1A331MED, ECA-1AM331, UVR1A331MED) carry ROHS3 compliance certification. This is relevant for applications subject to RoHS directives or customer requirements.

Q: Which substitute offers the best long-term availability?

A: ESMG100ELL331MF11D (Chemi-Con) and ECA-1AM331 (Panasonic) are both active products, indicating ongoing manufacturing and distribution. The remaining substitutes (UFW1A331MED, UKW1A331MED, UVR1A331MED) are obsolete. For new designs or long-term production, prioritize active products.

Q: Can I use these substitutes interchangeably on the same PCB?

A: Electrical interchangeability is confirmed across all parts. Mechanical interchangeability requires verification of height clearance. Parts with 0.433" height (SMG10VB331M6X11LL, UFW1A331MED, UKW1A331MED) fit the same footprint. Parts with 0.480" or 0.492" height (ECA-1AM331, ESMG100ELL331MF11D, UVR1A331MED) require clearance verification. Lead spacing (0.098" / 2.50mm) and diameter (0.248" / 6.30mm) are identical across all parts.

Q: What is the significance of the SMG series designation?

A: The SMG series is a Chemi-Con product line designation. ESMG100ELL331MF11D is also from the SMG series but carries a different part number structure. Both are Chemi-Con products with identical electrical specifications and are mechanically compatible.
