UDB1H2R2MPM Equivalent & Substitute Parts

Part Overview

The UDB1H2R2MPM is a 2.2 µF, 50 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 1000 hours at 85°C and is designed for audio applications. The part is currently active in production. Equivalent and substitute parts are necessary when the primary part is unavailable, when design requirements demand extended operational lifetime, or when alternative packaging formats are required for manufacturing processes.

Substitute Part Grouping Explanation

Substitution eligibility for the UDB1H2R2MPM is determined by the following mandatory parameters:

Capacitance: 2.2 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Bi-Polar (exact match required)
Operating Temperature Range: -40°C ~ 85°C (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in lead spacing, physical dimensions, lifetime rating, and packaging format (Bulk vs. Cut Tape) are permitted within the substitution scope, provided the core parameters remain unchanged.

Engineering Selection Recommendations

UDB1H2R2MPM (Primary Part) Active product status with ROHS3 compliance. Suitable for new designs and ongoing production. Recommended when lead spacing of 0.197" (5.00mm) and larger physical dimensions (10.00mm diameter) are compatible with PCB layout requirements.

ECE-A1HN2R2UB (Panasonic) Active product status with ROHS3 compliance and Cut Tape packaging. Preferred substitute when automated assembly processes require tape-and-reel format. Maintains identical lead spacing (0.197", 5.00mm) and similar height profile (0.472", 12.00mm) to the primary part. Extended lifetime rating of 2000 hours at 85°C provides enhanced reliability margin.

ECE-A1HN2R2U (Panasonic) Active product status with ROHS3 compliance and Bulk packaging. Suitable for applications where reduced physical footprint is acceptable. Reduced lead spacing (0.079", 2.00mm) and smaller diameter (0.197", 5.00mm) require PCB layout verification. Extended lifetime rating of 2000 hours at 85°C.

UVP1H2R2MDD (Nichicon) Obsolete product status. Not recommended for new designs. May be considered only for legacy system maintenance or repair applications where exact form-factor compatibility is critical and extended lifetime (2000 hours at 85°C) is required. Reduced lead spacing (0.079", 2.00mm) and smaller physical dimensions require PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can ECE-A1HN2R2UB be used as a direct replacement for UDB1H2R2MPM? A: Yes, provided PCB layout accommodates the identical lead spacing (0.197", 5.00mm). Both parts share the same capacitance, voltage rating, tolerance, polarization, and operating temperature range. The primary difference is packaging format (Cut Tape vs. Bulk) and extended lifetime rating (2000 vs. 1000 hours at 85°C).

Q: What are the implications of using ECE-A1HN2R2U with reduced lead spacing? A: ECE-A1HN2R2U has lead spacing of 0.079" (2.00mm) compared to the primary part's 0.197" (5.00mm). This requires verification that PCB through-hole pad spacing accommodates the reduced lead spacing. Physical dimensions are also smaller (0.197" diameter vs. 0.394" diameter). Electrical performance remains equivalent.

Q: Why is UVP1H2R2MDD listed as obsolete? A: UVP1H2R2MDD is marked as obsolete product status. While it meets all core electrical parameters, it is no longer in active production. Use is limited to legacy system maintenance or repair applications where no alternative is available.

Q: Does packaging format (Bulk vs. Cut Tape) affect electrical performance? A: No. Packaging format affects only manufacturing and assembly processes. ECE-A1HN2R2UB (Cut Tape) and ECE-A1HN2R2U (Bulk) are electrically identical to the primary part and to each other, differing only in how they are supplied and handled during assembly.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts, including the primary UDB1H2R2MPM and all substitutes, are ROHS3 compliant.
