UPW2D2R2MEH Equivalent & Substitute Parts

Part Overview

The UPW2D2R2MEH is a 2.2 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications.

Substitute Part Grouping Explanation

Substitution for the UPW2D2R2MEH is determined by strict equivalence across the following parameters: capacitance (2.2 µF), voltage rating (200 V minimum), tolerance (±20%), thermal lifetime (2000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), polarization (polar), package type (radial, can), lead spacing (0.098" / 2.50 mm), and case diameter (0.248" / 6.30 mm). All substitute parts must maintain through-hole mounting compatibility and support the specified ripple current ratings.

The substitute parts are grouped into two categories:

Direct Equivalents (200 V Rating): Parts meeting all specifications at the original 200 V voltage rating.

Upgrade Substitute (250 V Rating): Parts exceeding the original voltage specification, providing enhanced voltage margin while maintaining all other electrical and mechanical parameters.

Engineering Selection Recommendations

UPW2D2R2MED: This direct equivalent from Nichicon maintains identical electrical specifications and mechanical dimensions to the UPW2D2R2MEH. It achieves RoHS3 compliance and is available in bulk packaging. This part is suitable for direct replacement in existing designs where the original part is no longer available, though it remains obsolete.

SEK2R2M200ST: This Cornell Dubilier Electronics alternative provides equivalent electrical performance at 200 V with active product status. It features specified ESR characteristics (90.47 Ω @ 120 Hz) and RoHS3 compliance. The case height is 0.453" (11.50 mm) versus 0.433" (11.00 mm) for the original part, requiring PCB layout verification. This part is recommended for new designs requiring an active, compliant substitute.

SEK2R2M250ST: This upgrade substitute from Cornell Dubilier Electronics provides 250 V voltage rating while maintaining 2.2 µF capacitance and all other electrical specifications. It offers enhanced voltage margin for applications operating near the 200 V limit. The increased ripple current ratings (29 mA @ 120 Hz, 46.4 mA @ 10 kHz) provide additional thermal headroom. Case height is 0.453" (11.50 mm). This part is recommended for designs requiring improved reliability margins or where voltage stress reduction is beneficial.

Frequently Asked Questions (FAQ)

Q: Can UPW2D2R2MED be used as a direct replacement for UPW2D2R2MEH?

A: Yes. UPW2D2R2MED is electrically and mechanically equivalent to UPW2D2R2MEH, with identical capacitance (2.2 µF), voltage rating (200 V), tolerance (±20%), thermal lifetime (2000 Hrs @ 105°C), operating temperature range, and package dimensions. Both parts are obsolete; however, UPW2D2R2MED achieves RoHS3 compliance.

Q: What is the primary difference between SEK2R2M200ST and SEK2R2M250ST?

A: The voltage rating differs: SEK2R2M200ST is rated 200 V, while SEK2R2M250ST is rated 250 V. Both maintain 2.2 µF capacitance and identical thermal specifications. SEK2R2M250ST provides higher voltage margin and increased ripple current capacity (29 mA @ 120 Hz versus 25 mA, and 46.4 mA @ 10 kHz versus 40 mA).

Q: Are there PCB layout considerations when substituting with Cornell Dubilier parts?

A: Yes. SEK2R2M200ST and SEK2R2M250ST have a maximum seated height of 0.453" (11.50 mm) compared to 0.433" (11.00 mm) for the original UPW2D2R2MEH. Lead spacing (0.098" / 2.50 mm) and case diameter (0.248" / 6.30 mm) remain identical. Verify clearance above the component on the PCB before substitution.

Q: Which substitute part is recommended for new designs?

A: SEK2R2M200ST or SEK2R2M250ST are recommended for new designs. Both are active products with RoHS3 compliance. SEK2R2M250ST is preferred if voltage margin enhancement is desired or if the application can tolerate the slightly increased height.

Q: Are all substitute parts RoHS compliant?

A: UPW2D2R2MED, SEK2R2M200ST, and SEK2R2M250ST are all RoHS3 compliant. The original UPW2D2R2MEH is RoHS non-compliant.

Q: What is the inventory status of these parts?

A: UPW2D2R2MEH: 991 Pcs. UPW2D2R2MED: 4189 Pcs. SEK2R2M200ST: 1015 Pcs. SEK2R2M250ST: 1027 Pcs.
