UPJ2W010MPD Equivalent & Substitute Parts

Part Overview

The UPJ2W010MPD is a 1 µF, 450 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is designed for general-purpose applications requiring polar capacitance in through-hole configurations. The part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the UPJ2W010MPD is determined by strict equivalence across the following parameters: capacitance (1 µF), voltage rating (450 V), tolerance (±20%), polarization (polar), and through-hole mounting configuration. Parts are grouped into two categories:

Direct Substitutes (Identical Electrical & Mechanical Specifications): Parts maintaining the same capacitance, voltage, tolerance, operating temperature range, and physical footprint (lead spacing, diameter, height) as the main part. These parts are mechanically and electrically interchangeable without circuit redesign.

Similar Substitutes (Equivalent Electrical Specifications with Dimensional or Lifetime Variations): Parts matching capacitance, voltage, tolerance, and operating temperature but differing in physical dimensions (lead spacing, diameter, height) or thermal lifetime ratings. These require PCB layout verification before implementation.

Engineering Selection Recommendations

For Direct Replacement (No PCB Modification Required): UPJ2W010MPD1TD is the direct equivalent in cut tape packaging. Both parts maintain identical electrical specifications (1 µF, 450 V, ±20%, 5000 Hrs @ 105°C) and physical dimensions (0.197" lead spacing, 0.394" diameter, 0.650" height). This part is classified as "Not For New Designs" but remains functionally equivalent for legacy system support.

For Active Product Status with Equivalent Specifications: ECA-2WHG010B (Panasonic) and ECA-2WHG010BJ (Panasonic) are active products meeting the electrical requirements (1 µF, 450 V, ±20%, 2000 Hrs @ 105°C). Both are ROHS3 compliant. ECA-2WHG010B maintains the 0.197" lead spacing of the original part, requiring only diameter and height verification (0.315" diameter, 0.492" height). ECA-2WHG010BJ uses 0.138" lead spacing and requires PCB layout modification.

For Extended Thermal Lifetime with Dimensional Compatibility: UPW2W010MPD (Nichicon) maintains 5000-hour thermal rating at 105°C with identical lead spacing (0.197") and diameter (0.394") but reduced height (0.492" vs. 0.650"). This part is suitable for space-constrained applications where the original height is not a design constraint.

For Active Product with Reduced Thermal Lifetime: EKMG451ELL1R0MJC5S (Chemi-Con) is an active product with identical physical dimensions (0.197" lead spacing, 0.394" diameter, 0.551" height) but rated for 1000 hours at 105°C. This part is suitable only where thermal lifetime requirements are less stringent than the original 5000-hour specification.

Frequently Asked Questions (FAQ)

Q: Can UPJ2W010MPD1TD be used as a direct replacement for UPJ2W010MPD? A: Yes. Both parts are electrically and mechanically identical (1 µF, 450 V, ±20%, 5000 Hrs @ 105°C, 0.197" lead spacing, 0.394" diameter, 0.650" height). The only difference is packaging format (cut tape vs. bulk). No circuit or PCB modifications are required.

Q: What is the primary difference between Nichicon and Panasonic substitutes? A: Nichicon parts (UPJ, UPS, UPW, UVZ series) and Panasonic parts (ECA-2WH series) differ in thermal lifetime ratings and physical dimensions. Panasonic ECA-2WHG010 and ECA-2WHG010B are active products with 2000-hour ratings, while Nichicon UPJ and UPW series offer 5000-hour ratings. Lead spacing and diameter vary across manufacturers.

Q: Can ECA-2WHG010 be used without PCB modification? A: ECA-2WHG010 requires PCB layout verification. While it maintains the 1 µF, 450 V electrical specification, its physical dimensions differ: 0.138" lead spacing (vs. 0.197"), 0.315" diameter (vs. 0.394"), and 0.492" height (vs. 0.650"). Verify that the PCB footprint accommodates these dimensions before implementation.

Q: Which substitute offers the best availability and active product status? A: ECA-2WHG010B and ECA-2WHG010BJ (Panasonic) are both active products with substantial inventory (623 and 1136 units respectively). Both maintain the 1 µF, 450 V, ±20% electrical specification and ROHS3 compliance. ECA-2WHG010B is preferred if 0.197" lead spacing is required; ECA-2WHG010BJ uses 0.138" spacing.

Q: What is the thermal lifetime impact of using EKMG451ELL1R0MJC5S? A: EKMG451ELL1R0MJC5S is rated for 1000 hours at 105°C, compared to the original 5000-hour rating. This part is suitable only for applications where thermal lifetime requirements are reduced or where operating temperatures remain below 105°C for extended periods. Verify application thermal stress before selection.

Q: Does lead spacing affect circuit performance? A: Lead spacing affects PCB layout and mechanical fit only. Electrical performance is not affected by lead spacing differences. However, PCB footprints must be verified to accommodate the specific lead spacing of the selected substitute. Parts with 0.138" spacing require different PCB hole patterns than parts with 0.197" spacing.
