UPM2W010MPD Equivalent & Substitute Parts

Part Overview

The UPM2W010MPD is a 1 µF, 450 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, necessitating identification of equivalent alternatives for ongoing applications. The part features AEC-Q200 automotive qualification and is rated for 5000 hours at 105°C operating temperature. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, and thermal performance specifications while accommodating variations in physical dimensions and packaging formats.

Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Operating Temperature Range: -25°C to 105°C (exact match required)

Secondary Compatibility Criteria:

Lifetime @ 105°C: 5000 Hrs minimum for direct substitution; lower ratings (2000 Hrs, 1000 Hrs) represent reduced thermal endurance
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

Physical Dimension Tolerance:

Lead Spacing: 0.197" (5.00mm) preferred; 0.138" (4.60mm) acceptable with PCB layout verification

Engineering Selection Recommendations

Direct Substitutes (Preferred for Replacement):

UPJ2W010MPD and UPJ2W010MPD1TD maintain full electrical equivalence with 5000-hour thermal lifetime at 105°C. Both are Nichicon products within the same manufacturer ecosystem. UPJ2W010MPD1TD in Cut Tape packaging offers superior handling for automated assembly processes. Both parts are classified as obsolete or not for new designs, indicating limited long-term availability.

UPM2W010MPD1TD provides identical electrical and thermal specifications to the main part with Cut Tape packaging. This variant maintains AEC-Q200 automotive qualification and is suitable for applications requiring automotive-grade reliability. Product status is not for new designs.

Acceptable Substitutes (Thermal Lifetime Reduced):

UPS2W010MPD and UPW2W010MPD are Nichicon products with reduced thermal lifetime (2000 hours and 5000 hours respectively at 105°C). Both maintain identical electrical parameters and lead spacing. UPW2W010MPD offers the lowest profile at 0.492" height, beneficial for space-constrained applications. UPS2W010MPD provides intermediate height at 0.551".

Cross-Manufacturer Alternatives (Active Status):

ECA-2WHG010, ECA-2WHG010B, and ECA-2WHG010BJ are Panasonic products with active product status, ensuring ongoing availability. All three maintain 1 µF, 450 V, ±20% specifications with 2000-hour thermal lifetime. Physical dimensions vary: ECA-2WHG010 and ECA-2WHG010BJ feature 0.138" lead spacing and 0.315" diameter; ECA-2WHG010B features 0.197" lead spacing with 0.315" diameter. These dimensional variations require PCB layout verification before implementation.

EKMG451ELL1R0MJC5S is a Chemi-Con product with active status. It maintains 1 µF, 450 V specifications with 1000-hour thermal lifetime. Physical dimensions match the main part (0.197" lead spacing, 0.394" diameter, 0.551" height). This part is suitable for applications where thermal lifetime requirements are less stringent.

Dimensional Considerations:

Applications with strict PCB space constraints may accommodate smaller-diameter alternatives (0.315" vs. 0.394"). Lead spacing variations (0.138" vs. 0.197") require verification against PCB trace routing and component placement density. Height variations range from 0.492" to 0.669"; clearance above the capacitor must be confirmed for all substitutes.

Frequently Asked Questions (FAQ)

Q: Can UPS2W010MPD replace UPM2W010MPD in automotive applications?

A: UPS2W010MPD maintains identical electrical specifications (1 µF, 450 V, ±20%) and lead spacing. However, thermal lifetime is reduced from 5000 hours to 2000 hours at 105°C. Substitution is acceptable only if application thermal stress does not exceed 2000-hour endurance requirements. AEC-Q200 automotive qualification is not listed for UPS2W010MPD; verify compliance requirements with your application specification.

Q: What is the difference between UPJ2W010MPD and UPJ2W010MPD1TD?

A: Both parts are electrically and thermally identical (1 µF, 450 V, 5000 Hrs @ 105°C). The primary difference is packaging: UPJ2W010MPD is supplied in bulk; UPJ2W010MPD1TD is supplied in cut tape format. Cut tape packaging is preferred for automated pick-and-place assembly. Both are Nichicon products with obsolete or not-for-new-designs status.

Q: Are Panasonic ECA-2WHG010 series parts suitable replacements?

A: ECA-2WHG010, ECA-2WHG010B, and ECA-2WHG010BJ maintain electrical equivalence (1 µF, 450 V, ±20%) with active product status, ensuring availability. Thermal lifetime is 2000 hours at 105°C, compared to 5000 hours for the main part. Physical dimensions differ: lead spacing is 0.138" or 0.197" (vs. 0.197" for UPM2W010MPD), and diameter is 0.315" (vs. 0.394"). PCB layout verification is required before substitution.

Q: Can I use EKMG451ELL1R0MJC5S as a direct replacement?

A: EKMG451ELL1R0MJC5S (Chemi-Con) matches electrical specifications and physical dimensions (0.197" lead spacing, 0.394" diameter). Thermal lifetime is 1000 hours at 105°C, significantly lower than the main part's 5000 hours. This part is suitable only for applications with reduced thermal stress requirements. Active product status ensures availability.

Q: What are the implications of reduced thermal lifetime in substitute parts?

A: Thermal lifetime (measured in hours at 105°C) indicates capacitor endurance under elevated temperature stress. Reduced lifetime (2000 or 1000 hours vs. 5000 hours) means the capacitor reaches end-of-life sooner under continuous high-temperature operation. Substitution with lower-lifetime parts is acceptable only if application operating temperature and duty cycle do not approach or exceed the substitute part's rated thermal endurance.

Q: How do physical dimension variations affect PCB compatibility?

A: Lead spacing (0.138" vs. 0.197") determines PCB pad pitch; mismatches require PCB redesign. Diameter (0.315" vs. 0.394") affects component placement density and clearance to adjacent components. Height (0.492" to 0.669") must clear overlying components or enclosure constraints. Verify all three dimensions against PCB layout and mechanical assembly drawings before finalizing substitution.

Q: Why is UVZ2W010MPD listed as a similar part rather than a direct substitute?

A: UVZ2W010MPD maintains electrical equivalence (1 µF, 450 V, ±20%) but has reduced thermal lifetime (1000 hours vs. 5000 hours). Additionally, physical dimensions differ significantly: lead spacing is 0.138" (vs. 0.197"), diameter is 0.315" (vs. 0.394"), and height is 0.512" (vs. 0.669"). These dimensional variations require PCB layout verification, and the reduced thermal lifetime limits applicability to lower-stress environments.

Q: What does "Not For New Designs" product status mean?

A: Parts marked "Not For New Designs" are in end-of-life phase. Manufacturers continue production for existing customer support but do not recommend these parts for new product development. Availability may be limited and pricing may increase. For new designs, prioritize parts with "Active" status such as ECA-2WHG010 series or EKMG451ELL1R0MJC5S.
