UPW2W010MPD Equivalent & Substitute Parts

Part Overview

The UPW2W010MPD is a 1 µF, 450 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part operates across a temperature range of -25°C to 105°C with a rated lifetime of 5000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Substitute Part Grouping Explanation

Substitution eligibility for the UPW2W010MPD is determined by the following criteria:

Capacitance: 1 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature: -25°C ~ 105°C (exact match required)
RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

Substitute parts are grouped into two categories based on lifetime rating at 105°C:

Category A - Extended Lifetime (5000 Hrs @ 105°C): UPW2W010MPD (main part)

Category B - Standard Lifetime (2000 Hrs @ 105°C): UPJ2W010MPD, UPS2W010MPD, ECA-2WHG010, ECA-2WHG010B, ECA-2WHG010BJ

Category C - Reduced Lifetime (1000 Hrs @ 105°C): UVZ2W010MPD, EKMG451ELL1R0MJC5S

All substitute parts meet the core electrical and mechanical requirements. Differences exist in physical dimensions (lead spacing, height, diameter) and ripple current ratings, which must be evaluated against specific circuit board layout and thermal management constraints.

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

ECA-2WHG010, ECA-2WHG010B, and ECA-2WHG010BJ are manufactured by Panasonic Electronic Components and carry Active product status. These parts meet all electrical and mechanical requirements with ROHS3 compliance. ECA-2WHG010B and ECA-2WHG010BJ offer lead spacing compatibility with the original UPW2W010MPD (0.197" and 0.138" respectively), supporting direct board layout substitution.

Secondary Substitutes (Nichicon Series):

UPS2W010MPD maintains Nichicon manufacturing continuity with identical lead spacing and ripple current ratings to the UPW2W010MPD. The reduced lifetime rating of 2000 hours at 105°C versus the original 5000 hours requires thermal management evaluation for applications with extended operational cycles at elevated temperatures.

Limited Substitutes (Reduced Performance):

UVZ2W010MPD and EKMG451ELL1R0MJC5S feature reduced lifetime ratings of 1000 hours at 105°C and lower ripple current capacity. UVZ2W010MPD carries a "Not For New Designs" status. These parts are suitable only for applications with lower thermal stress or shorter operational lifespans.

Obsolete Series Consideration:

UPJ2W010MPD, while maintaining 5000-hour lifetime rating, is classified as obsolete. The increased height of 0.650" (16.50mm) versus the original 0.492" (12.50mm) may create board layout conflicts in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can ECA-2WHG010B directly replace UPW2W010MPD on existing circuit boards?

A: ECA-2WHG010B matches the lead spacing of 0.197" (5.00mm) and height of 0.492" (12.50mm), supporting direct board-level substitution. However, the diameter is reduced from 0.394" (10.00mm) to 0.315" (8.00mm), which may affect mechanical stability in high-vibration environments. Verify mounting hole compatibility and mechanical support.

Q: What is the impact of reduced lifetime ratings in UPS2W010MPD and EKMG451ELL1R0MJC5S?

A: Lifetime ratings indicate capacitor reliability under continuous operation at maximum rated temperature (105°C). UPS2W010MPD (2000 Hrs) and EKMG451ELL1R0MJC5S (1000 Hrs) have shorter rated lifespans than the original UPW2W010MPD (5000 Hrs). Applications requiring extended operation at elevated temperatures must account for accelerated aging and potential early failure. Thermal management improvements or derating strategies may extend practical service life.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, meeting regulatory requirements for hazardous substance restrictions.

Q: Which substitute offers the best compatibility with the original UPW2W010MPD?

A: UPJ2W010MPD maintains identical electrical specifications and 5000-hour lifetime rating. However, its increased height of 0.650" (16.50mm) may conflict with board layouts designed for the original 0.492" (12.50mm) height. ECA-2WHG010B provides superior physical compatibility with matching lead spacing and height, though it is manufactured by Panasonic rather than Nichicon.

Q: Can ripple current differences affect circuit performance?

A: Ripple current ratings define the maximum AC current the capacitor can handle without exceeding temperature limits. The UPW2W010MPD handles 28.8 mA at 10 kHz. Substitutes with lower ripple current ratings (UVZ2W010MPD at 20.8 mA, EKMG451ELL1R0MJC5S at 32.5 mA @ 100 kHz) may require thermal analysis if the circuit operates near rated ripple current limits. Higher ripple current capacity provides additional thermal margin.

Q: Is UVZ2W010MPD suitable for new designs?

A: UVZ2W010MPD carries a "Not For New Designs" status and features reduced lifetime (1000 Hrs @ 105°C) and ripple current capacity (13 mA @ 120 Hz). It is not recommended for new product development. Use only for legacy system maintenance or applications with minimal thermal stress.
