UPM2E010MPD Equivalent & Substitute Parts

Part Overview

The UPM2E010MPD is a 1 µF, 250 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement. The UPM series has been superseded by newer product lines, making alternative sourcing critical for applications requiring this capacitance and voltage rating.

Substitute Part Grouping Explanation

Substitution of the UPM2E010MPD is determined by the following critical parameters:

Electrical equivalence: Capacitance (1 µF), voltage rating (250 V minimum), and tolerance (±20%)
Thermal performance: Lifetime rating at 105°C (3000 Hrs minimum preferred)
Mechanical compatibility: Through-hole radial can package with matching lead spacing and physical dimensions
Regulatory compliance: ROHS3 compliance and automotive-grade ratings where applicable

Substitute parts are grouped into three categories:

Direct Equivalent (Same Series Upgrade): UPJ2E010MPD1TD maintains identical electrical and mechanical specifications with improved availability. UPJ2F010MPD1TD provides voltage upgrade capability (315 V) while maintaining all other parameters.

Similar Equivalents (Different Manufacturers): MAL214231083E3, MAL214251083E3, and MAL214271083E3 (Vishay) meet core electrical requirements with minor dimensional variations in lead spacing and diameter. SEK010M250ST (Cornell Dubilier) provides functional equivalence with documented ESR specification.

Functional Alternatives (Reduced Thermal Rating): UPS2E010MED (Nichicon) maintains electrical and mechanical compatibility but operates at 2000 Hrs @ 105°C, representing a reduced lifetime specification.

Engineering Selection Recommendations

Primary Selection: UPJ2E010MPD1TD is the direct equivalent from Nichicon with identical electrical specifications and 3000 Hrs lifetime rating. Although marked "Not For New Designs," this part maintains full compatibility with the original UPM2E010MPD footprint and performance envelope.

Voltage Upgrade Path: UPJ2F010MPD1TD provides 315 V rating while maintaining 1 µF capacitance and 3000 Hrs lifetime. This option is suitable for applications where increased voltage margin is acceptable and PCB layout permits the minor height reduction (0.492" vs. 0.512").

Active Product Alternatives: Vishay MAL214231083E3, MAL214251083E3, and MAL214271083E3 are active products with ROHS3 compliance. These parts meet core electrical requirements but feature reduced lifetime (2500 Hrs) and dimensional variations in lead spacing and diameter. PCB layout verification is required before substitution.

Functional Alternative: SEK010M250ST (Cornell Dubilier) is an active product with documented ESR (199.04 Ohm) and 2000 Hrs lifetime. Dimensional differences in height (0.433" vs. 0.512") and diameter (0.248" vs. 0.315") require PCB layout confirmation.

All substitute options maintain ROHS3 compliance and operate across the -40°C ~ 105°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can UPJ2E010MPD1TD directly replace UPM2E010MPD?

A: Yes. Both parts share identical capacitance (1 µF), voltage rating (250 V), tolerance (±20%), and lifetime (3000 Hrs @ 105°C). The lead spacing (0.138" / 4.60mm) and diameter (0.315" / 8.00mm) are identical. Height differs by 0.020" (0.50mm), which is typically accommodated in standard PCB layouts.

Q: What is the difference between UPJ2E010MPD1TD and UPJ2F010MPD1TD?

A: The primary difference is voltage rating: UPJ2E010MPD1TD is rated 250 V, while UPJ2F010MPD1TD is rated 315 V. Both maintain 1 µF capacitance and 3000 Hrs lifetime. UPJ2F010MPD1TD is suitable for applications requiring higher voltage margin.

Q: Can Vishay MAL214 series parts replace the UPM2E010MPD?

A: Electrical substitution is possible (1 µF, 250 V, ±20%, ROHS3). However, lead spacing and diameter vary across the MAL214 series. MAL214231083E3 has 0.197" lead spacing and 0.197" diameter. MAL214251083E3 has 0.079" lead spacing and 0.197" diameter. MAL214271083E3 has 0.098" lead spacing and 0.197" diameter. PCB layout verification is mandatory before selection. Lifetime is reduced to 2500 Hrs.

Q: Why is the lifetime specification important for substitution?

A: Lifetime at 105°C determines component reliability under thermal stress. The UPM2E010MPD specifies 3000 Hrs @ 105°C. Substitutes with lower ratings (2000-2500 Hrs) may not meet application reliability requirements. UPJ2E010MPD1TD maintains the 3000 Hrs specification, making it the preferred equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original UPM2E010MPD specification.

Q: What packaging options are available?

A: UPM2E010MPD is supplied in standard packaging. UPJ2E010MPD1TD is available in Cut Tape (CT). Vishay MAL214 series parts are available in Tape & Box (TB) or Bulk packaging. SEK010M250ST packaging is not specified. Verify packaging requirements for your procurement process.
