UPW2D2R2MED Equivalent & Substitute Parts

Part Overview

The UPW2D2R2MED is a 2.2 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, though 4189 units remain in stock. The UPW series offers a 2000-hour lifetime rating at 105°C with general-purpose applications in through-hole designs. Due to its obsolete status, equivalent and substitute parts from active manufacturers provide continuity for ongoing production and maintenance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the UPW2D2R2MED is determined by the following criteria:

Primary Electrical Parameters: Capacitance (2.2 µF), voltage rating (200 V minimum), and tolerance (±20%) must match exactly.

Mechanical Compatibility: Lead spacing (0.098" / 2.50mm) and package type (radial, can) must be identical to ensure PCB footprint compatibility.

Thermal & Reliability: Operating temperature range (-40°C ~ 105°C) and lifetime rating (2000 hours minimum @ 105°C) establish minimum performance thresholds.

Compliance: RoHS3 compliance is required for regulatory alignment.

Substitute parts are grouped into two categories:

Direct Equivalents – Parts matching all electrical, mechanical, and thermal specifications with identical lead spacing and dimensions.
Functional Equivalents – Parts with identical electrical ratings but different mechanical dimensions (lead spacing or height), suitable only when PCB layout permits.

Engineering Selection Recommendations

Direct Mechanical Equivalents (Identical Lead Spacing 0.098" / 2.50mm):

MAL214252228E3 and MAL214272228E3 (Vishay) are direct mechanical substitutes with matching lead spacing, diameter, and electrical ratings. Both are active products with 2500-hour lifetime ratings, exceeding the 2000-hour minimum. These parts require no PCB layout modification.

SEK2R2M200ST (Cornell Dubilier Electronics) provides an active alternative with identical lead spacing and electrical specifications. This part carries RoHS3 compliance and MSL rating of 1 (Unlimited), suitable for moisture-sensitive environments.

SEK2R2M250ST (Cornell Dubilier Electronics) offers a higher voltage rating (250 V) with matching mechanical dimensions and lead spacing. This upgrade option provides additional voltage margin while maintaining identical PCB footprint compatibility.

Functional Equivalent (Different Lead Spacing):

UPJ2D2R2MPD (Nichicon) matches electrical specifications but features 0.138" (4.60mm) lead spacing, requiring PCB layout verification. This part is obsolete but offers extended 3000-hour lifetime at 105°C.

MAL214232228E3 (Vishay) has 0.197" (5.00mm) lead spacing, incompatible with the original UPW2D2R2MED footprint without layout modification.

Product Status Consideration:

Active manufacturer parts (Vishay 142 RHS series and Cornell Dubilier SEK series) ensure long-term availability and supply chain continuity. The Nichicon UPJ2D2R2MPD remains obsolete, limiting future procurement options.

Frequently Asked Questions (FAQ)

Q: Can MAL214252228E3 or MAL214272228E3 replace UPW2D2R2MED without PCB modification?

A: Yes. Both Vishay parts have identical lead spacing (0.098" / 2.50mm), diameter (0.248" / 6.30mm), and electrical ratings (2.2 µF, 200 V, ±20%). The height difference (0.492" vs. 0.433") does not affect electrical function or standard through-hole mounting. Both are active products with 2500-hour lifetime ratings.

Q: What is the advantage of SEK2R2M250ST over SEK2R2M200ST?

A: SEK2R2M250ST provides a 250 V rating compared to 200 V in SEK2R2M200ST. Both share identical mechanical dimensions and lead spacing. The higher voltage rating offers additional safety margin in applications subject to voltage transients or overvoltage conditions. Electrical performance and PCB compatibility remain identical.

Q: Why does UPJ2D2R2MPD have different lead spacing?

A: UPJ2D2R2MPD uses 0.138" (4.60mm) lead spacing versus the original 0.098" (2.50mm). This requires PCB footprint verification before substitution. The part is obsolete, making it unsuitable for new designs despite its extended 3000-hour lifetime rating.

Q: Are all substitute parts RoHS3 compliant?

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

Q: What is the difference between Tape & Box (TB) and Bulk packaging?

A: Packaging type affects order quantities and handling but does not impact electrical or mechanical performance. Tape & Box packaging is standard for automated assembly lines, while Bulk packaging suits manual assembly or smaller production runs. Electrical specifications remain identical regardless of packaging format.

Q: Can I use MAL214232228E3 with 0.197" lead spacing in place of UPW2D2R2MED?

A: No, without PCB layout modification. The 0.197" (5.00mm) lead spacing is incompatible with the original 0.098" (2.50mm) footprint. PCB drilling and trace routing would require redesign.
