UMP1H2R2MDD Equivalent & Substitute Parts

Part Overview

The UMP1H2R2MDD is a 2.2 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications. The product status is obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UMP1H2R2MDD is determined by the following critical parameters:

• Electrical Equivalence: Capacitance (2.2 µF), voltage rating (50 V), and tolerance (±20%) must match exactly
• Thermal Performance: Lifetime rating at operating temperature must meet or exceed 2000 Hrs @ 85°C
• Physical Compatibility: Mounting type (through hole), package style (radial, can), and lead spacing must accommodate existing PCB layouts
• Environmental Compliance: RoHS3 compliance is required

Substitute parts are grouped into two categories:

Category 1 - Through Hole Radial Equivalents: Parts maintaining identical mounting type and lead spacing (0.079" / 2.00mm) for direct PCB replacement without layout modification.

Category 2 - Surface Mount Alternative: Parts with modified mounting type (surface mount) for designs requiring SMD technology, with adjusted thermal and dimensional specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Through Hole Replacement (Preferred for PCB Compatibility)

ECE-A1HN2R2U and ECE-A1HN2R2UB (Panasonic) are the primary substitutes. Both maintain identical electrical specifications (2.2 µF, 50 V, ±20%, 2000 Hrs @ 85°C) and through-hole mounting with 0.079" lead spacing. Both are active products with ROHS3 compliance. ECE-A1HN2R2UB is available in cut tape packaging, while ECE-A1HN2R2U is supplied in bulk. Height differences (0.472" vs. 0.236") require clearance verification in space-constrained applications.

Alternative Through Hole Options

UVP1H2R2MDD (Nichicon) matches all electrical and thermal specifications with identical lead spacing. Product status is obsolete, limiting long-term availability. Height is 0.433", requiring clearance assessment.

Larger Footprint Alternative

UDB1H2R2MPM (Nichicon) provides electrical equivalence but with reduced thermal rating (1000 Hrs @ 85°C vs. 2000 Hrs). Physical dimensions are significantly larger (0.394" diameter, 0.531" height, 0.197" lead spacing), requiring PCB layout modification. Active product status supports ongoing supply.

Surface Mount Alternative

UUP1H2R2MCL1GS (Nichicon) is suitable only for designs transitioning to surface mount technology. It maintains electrical specifications and offers extended operating temperature range (-55°C ~ 105°C) with 1000 Hrs @ 105°C rating. Mounting type and land pattern are incompatible with through-hole PCB designs.

Frequently Asked Questions (FAQ)

Q: Can ECE-A1HN2R2U or ECE-A1HN2R2UB be used as direct replacements for UMP1H2R2MDD?

A: Yes, both Panasonic parts are electrically and mechanically equivalent. They maintain 2.2 µF capacitance, 50 V rating, ±20% tolerance, and 2000 Hrs @ 85°C thermal performance. Lead spacing (0.079" / 2.00mm) is identical. Height differences (0.472" vs. 0.236") must be verified against PCB clearance requirements.

Q: What is the difference between ECE-A1HN2R2U and ECE-A1HN2R2UB?

A: Both parts are electrically and dimensionally identical. The difference is packaging: ECE-A1HN2R2U is supplied in bulk, while ECE-A1HN2R2UB is supplied in cut tape. Selection depends on procurement and assembly requirements.

Q: Why is UDB1H2R2MPM not recommended as a primary substitute?

A: While UDB1H2R2MPM is an active product, it has a reduced thermal rating (1000 Hrs @ 85°C vs. 2000 Hrs). Additionally, its larger physical dimensions (0.394" diameter, 0.531" height, 0.197" lead spacing) require PCB layout modification and may not fit existing through-hole patterns designed for the UMP1H2R2MDD.

Q: Can UUP1H2R2MCL1GS replace UMP1H2R2MDD in existing designs?

A: No. UUP1H2R2MCL1GS is a surface mount component, while UMP1H2R2MDD is through-hole. This substitution requires PCB redesign and is suitable only for new designs or major board revisions.

Q: What is the impact of different ripple current ratings?

A: Ripple current capacity affects thermal performance under AC stress. UMP1H2R2MDD is rated for 13 mA @ 120 Hz and 19.5 mA @ 10 kHz. Panasonic equivalents (ECE-A1HN2R2U, ECE-A1HN2R2UB) are rated for 18 mA @ 120 Hz and 30.6 mA @ 10 kHz, providing higher ripple current handling. UVP1H2R2MDD offers 25 mA @ 120 Hz and 50 mA @ 10 kHz. Selection should match or exceed the original design's ripple current requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of UMP1H2R2MDD.

Q: What is the advantage of ECE-A1HN2R2UB's cut tape packaging?

A: Cut tape packaging is suitable for automated assembly processes and reduces material waste compared to bulk packaging. It is preferred for high-volume production environments.
