Substitute Part Grouping Explanation

Substitution eligibility for the UPW2G010MPD is determined by strict equivalence across the following critical parameters:

Capacitance value: 1 µF (exact match required)
Voltage rating: 400 V (exact match required)
Tolerance: ±20% (exact match required)
Operating temperature range: -40°C to 105°C (exact match required)
Polarization: Polar (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial, Can (exact match required)
RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

Substitute parts may vary in the following parameters without affecting functional compatibility:

Lifetime @ 105°C (may be lower or higher)
Ripple current ratings (may vary within acceptable design margins)
Lead spacing (may differ if PCB layout permits)
Case diameter and height (may differ if physical space permits)
Packaging format (Bulk, Tape & Box acceptable)
Product status (Active preferred over Obsolete or Not For New Designs)

Engineering Selection Recommendations

Nichicon UPS2G010MPD: Direct Nichicon substitute with identical electrical specifications. Maintains 5.00 mm lead spacing and 10.00 mm case diameter. Height increases to 14.00 mm; verify PCB clearance. Lifetime reduced to 2000 hours; acceptable for applications not requiring extended thermal endurance. Obsolete status requires inventory planning.

Vishay MAL214231086E3: Active product status provides long-term availability. Maintains 5.00 mm lead spacing and 12.50 mm height. Case diameter reduces to 6.30 mm, enabling compact layouts. Ripple current capacity increases to 40.5 mA at 10 kHz. Tape & Box packaging suitable for automated assembly. 2500-hour lifetime at 105°C provides mid-range thermal performance.

Vishay MAL214251086E3 and MAL214271086E3: Active products with identical electrical and thermal specifications to MAL214231086E3. Lead spacing reduces to 2.50 mm, requiring PCB layout modification. Case diameter 6.30 mm. Ripple current 31.5 mA at 10 kHz. MAL214251086E3 supplied in Bulk; MAL214271086E3 in Tape & Box.

Cornell Dubilier SEK010M400ST: Active product with documented ESR specification (265.39 Ohm @ 120 Hz). Lead spacing 4.60 mm and case diameter 8.00 mm require PCB layout verification. Height 11.00 mm provides compact profile. Ripple current 36 mA at 10 kHz. 2000-hour lifetime. MSL rating 1 (Unlimited) indicates moisture tolerance suitable for diverse storage conditions.

Nichicon UVZ2G010MPD: Not recommended for new designs. Reduced 1000-hour lifetime and smaller physical dimensions (8.00 mm diameter, 4.60 mm lead spacing) limit applicability. Acceptable only for legacy system maintenance where physical constraints and thermal requirements align.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with lower lifetime rating?

A: Yes, provided the application thermal profile does not exceed the substitute part's rated lifetime at 105°C. Verify that the operating duty cycle and ambient temperature conditions remain within the substitute's specifications. Lower lifetime ratings are acceptable for applications with reduced thermal stress or shorter service intervals.

Q: What is the impact of different lead spacing on PCB compatibility?

A: Lead spacing directly determines PCB hole pattern compatibility. The UPW2G010MPD uses 5.00 mm spacing. Substitutes with 2.50 mm or 4.60 mm spacing require PCB redesign. Verify hole-to-hole distance before selecting a substitute with different lead spacing. Physical board layout modification may be necessary.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification, meeting regulatory requirements for hazardous substance restriction. All parts are REACH Unaffected and classified as EAR99 for export control purposes.

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

A: Vishay Beyschlag/Draloric/BC Components parts (MAL214231086E3, MAL214251086E3, MAL214271086E3) and Cornell Dubilier SEK010M400ST carry Active product status, ensuring continued manufacturing and supply. Nichicon UPS2G010MPD and UVZ2G010MPD are obsolete or not recommended for new designs.

Q: Can I use a substitute with higher ripple current rating?

A: Yes. Higher ripple current capacity provides design margin and thermal headroom. Substitutes with increased ripple current ratings (such as MAL214231086E3 at 40.5 mA @ 10 kHz versus UPW2G010MPD at 25.6 mA @ 10 kHz) are functionally compatible and may improve circuit reliability under ripple stress conditions.

Q: What packaging formats are available?

A: Substitute parts are supplied in Bulk, Tape & Box (TB), or unspecified packaging. Bulk packaging suits high-volume procurement. Tape & Box format supports automated pick-and-place assembly. Verify packaging compatibility with your procurement and assembly processes before finalizing part selection.
