Substitute Part Grouping Explanation

Substitution for the UVZ2E010MED is determined by the following critical parameters:

Primary Substitution Criteria:

Capacitance: 1 µF (exact match required)
Voltage Rating: 250 V minimum (equal or higher acceptable)
Tolerance: ±20% (standard for this category)
Lead Spacing: 0.098" (2.50mm) for direct PCB compatibility
Case Diameter: 0.248" (6.30mm) for mechanical fit
Mounting Type: Through Hole radial configuration

Engineering Selection Recommendations

Direct Mechanical Replacement (Preferred): UPS2E010MED (Nichicon) provides direct mechanical and electrical compatibility with identical lead spacing (0.098", 2.50mm) and case height (0.492", 12.50mm). This part offers extended lifetime (2000 hours at 105°C) compared to the original specification. Both parts are ROHS3 compliant and maintain the same operating temperature range.

Active Component Alternatives: 250PX1MEFC6.3X11 (Rubycon) is an active product with identical electrical specifications and lead spacing. Height is 0.512" (13.00mm), requiring verification of available PCB clearance. This part is ROHS3 compliant and suitable for new designs.

Voltage-Upgraded Options: UVZ2V010MED (Nichicon, 350 V), 400LEX1MEFC6.3X11 (Rubycon), 400LLE1MEFC6.3X11 (Rubycon), 400PX1MEFC6.3X11 (Rubycon), and EKMQ401ELL1R0MF11D (Chemi-Con) all provide higher voltage ratings (350 V or 400 V) with identical lead spacing (0.098", 2.50mm). These are electrically compatible in 250 V applications and offer improved design margin. All are ROHS3 compliant. The 400LLE1MEFC6.3X11 offers the longest lifetime specification (12000 hours at 105°C).

Mechanical Variants (Requires Layout Verification): MAL214231083E3 and MAL214251083E3 (Vishay) feature different lead spacing (0.197" and 0.079" respectively) and require PCB layout confirmation. Both are active products with extended lifetime (2500 hours at 105°C) and ROHS3 compliance.

517D105M250AA6AE3 (Vishay Sprague) has reduced height (0.433", 11.00mm) with extended lifetime (2000 hours at 105°C) and identical lead spacing, suitable for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V rated capacitor in place of a 250 V rated capacitor? A: Yes. Higher voltage-rated capacitors are electrically compatible in lower voltage applications. The 400 V parts listed maintain identical capacitance (1 µF), tolerance (±20%), and lead spacing (0.098", 2.50mm), providing additional design margin. All listed 400 V alternatives are ROHS3 compliant.

Q: What is the impact of different lead spacing on PCB compatibility? A: Lead spacing determines the distance between component pins on the PCB. The original UVZ2E010MED uses 0.098" (2.50mm) spacing. Parts with different spacing (such as MAL214231083E3 at 0.197" or MAL214251083E3 at 0.079") require PCB layout verification and may not fit existing footprints without modification.

Q: Why do some substitutes have different case heights? A: Case height variation is common across manufacturers. The original part is 0.492" (12.50mm). Alternatives range from 0.433" to 0.512". Height differences require verification of available PCB clearance, particularly in space-constrained designs. Taller components (0.512") may require layout adjustment.

Q: What does "lifetime at temperature" mean for capacitor selection? A: Lifetime specification indicates the expected operational duration at a given temperature before capacitance degradation reaches specified limits. The original UVZ2E010MED specifies 1000 hours at 105°C. Extended lifetime options (2000, 2500, 4000, or 12000 hours) provide longer service life under identical thermal conditions and are suitable for applications requiring improved reliability.

Q: Are all listed substitutes ROHS3 compliant? A: Yes. All parts listed in this reference maintain ROHS3 compliance, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What is the difference between "Obsolete" and "Active" product status? A: Active products are currently manufactured and available for new designs. Obsolete products are no longer in production but may have existing inventory. For new designs, active alternatives (250PX1MEFC6.3X11, 400LEX1MEFC6.3X11, 400LLE1MEFC6.3X11, 400PX1MEFC6.3X11, EKMQ401ELL1R0MF11D, MAL214231083E3, MAL214251083E3) are recommended to ensure long-term supply continuity.

Q: Can I substitute a part with different ripple current specifications? A: Ripple current capacity must meet or exceed the application requirement. Higher ripple current ratings provide additional margin and are acceptable substitutes. Verify that the selected part's ripple current specification matches or exceeds the circuit requirement before implementation.
