UES1H2R2MDM Equivalent & Substitute Parts

Part Overview

The UES1H2R2MDM is a 2.2 µF, 50 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 UES series is rated for 1000 hours at 85°C and is commonly used in audio applications. Substitute parts maintain the core electrical specifications (2.2 µF capacitance, 50 V rated voltage, ±20% tolerance) while offering improved thermal performance, extended lifetime ratings, or active product status.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters: capacitance (2.2 µF), rated voltage (50 V), tolerance (±20%), package type (radial, can), mounting method (through hole), lead spacing (0.079" / 2.00 mm), and physical dimensions (0.197" diameter / 5.00 mm). All substitute parts meet these core requirements. Secondary parameters including lifetime rating, operating temperature range, ripple current specifications, and product status are provided for engineering selection but do not disqualify substitution. All substitute parts maintain ROHS3 compliance and EAR99 export classification.

Engineering Selection Recommendations

For applications requiring active product status and long-term availability, 225BPS050M (Cornell Dubilier / Illinois Capacitor) and 50NXA2.2MEFC5X11 (Rubycon) are preferred selections. Both parts are currently active in production.

225BPS050M offers extended lifetime (2000 hours at 85°C) and is suitable for audio applications matching the original UES1H2R2MDM application profile. This part has a maximum seated height of 0.512" (13.00 mm), which is 0.020" taller than the main part; PCB layout verification is required.

50NXA2.2MEFC5X11 provides the widest operating temperature range (-55°C to 105°C) and is rated for 1000 hours at 105°C, supporting higher-temperature environments. This part maintains identical physical dimensions to the main part.

UEP1H2R2MDD (Nichicon) and 50NA2R2MEFC5X11 (Rubycon) are obsolete but available in inventory. UEP1H2R2MDD extends the operating temperature range to -55°C ~ 105°C. 50NA2R2MEFC5X11 provides 2000-hour lifetime at 85°C with identical physical dimensions.

All substitute parts maintain ROHS3 compliance and are classified as EAR99 for export purposes.

Frequently Asked Questions (FAQ)

Q: Can UES1H2R2MDM be directly replaced with any of these substitute parts?

A: Yes. All listed substitute parts are electrically and mechanically equivalent based on capacitance (2.2 µF), rated voltage (50 V), tolerance (±20%), package type (radial, can), and physical dimensions. Direct PCB substitution is possible with one exception: 225BPS050M has a maximum seated height of 0.512" (13.00 mm) versus 0.492" (12.50 mm) for the main part. Verify clearance in your specific PCB layout.

Q: Which substitute part should I select for new designs?

A: For new designs, select from active product status parts: 225BPS050M or 50NXA2.2MEFC5X11. 225BPS050M is recommended for audio applications with standard temperature ranges (-40°C to 85°C). 50NXA2.2MEFC5X11 is recommended for applications requiring extended temperature operation (-55°C to 105°C) or higher thermal environments.

Q: Are there differences in ripple current handling between these parts?

A: Yes. Ripple current specifications vary across substitute parts. 225BPS050M supports 25 mA at 120 Hz and 42.5 mA at 50 kHz. 50NXA2.2MEFC5X11 supports 14 mA at 120 Hz and 21 mA at 10 kHz. 50NA2R2MEFC5X11 supports 19 mA at 120 Hz and 28.5 mA at 10 kHz. Select based on your circuit's ripple current requirements.

Q: What is the difference between UEP1H2R2MDD and UES1H2R2MDM?

A: Both are Nichicon products with identical electrical specifications. UEP1H2R2MDD extends the operating temperature range to -55°C ~ 105°C and is rated for 1000 hours at 105°C, compared to UES1H2R2MDM's -40°C ~ 85°C range and 1000 hours at 85°C. Both are obsolete.

Q: Are all substitute parts RoHS compliant?

A: 225BPS050M, UEP1H2R2MDD, and 50NXA2.2MEFC5X11 are ROHS3 compliant. RoHS status for 50NA2R2MEFC5X11 is not specified in available data.

Q: Can I use these parts interchangeably in existing assemblies?

A: Physical and electrical interchangeability is confirmed for all parts except 225BPS050M, which has a 0.020" greater seated height. Verify PCB clearance before substitution. All parts use identical lead spacing (0.079" / 2.00 mm) and mounting method (through hole).
