URZ1H010MDD Equivalent & Substitute Parts

Part Overview

The URZ1H010MDD is a 1 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 1000 hours at 105°C, suitable for general-purpose filtering and energy storage applications in electronic circuits.

Substitute Part Grouping Explanation

Substitution eligibility for the URZ1H010MDD is determined by strict equivalence across the following parameters:

Capacitance: 1 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage - Rated: 50 V (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.079" (2.00 mm) (exact match required)
Size / Dimension: 0.197" Dia (5.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in lifetime rating, ripple current specifications, and physical height (within can package tolerance) do not disqualify substitution eligibility.

Engineering Selection Recommendations

Direct Substitutes (Electrical & Mechanical Equivalence)

All three substitute parts—517D105M050JA6AE3, EKMG500ELL1R0ME11D, and SEK010M050ST—are electrically and mechanically equivalent to the URZ1H010MDD. Selection among these options should prioritize product status and supply chain availability.

Active Product Status Priority: EKMG500ELL1R0ME11D (Chemi-Con, Active) and SEK010M050ST (CDE, Active) are currently in active production. These parts offer superior long-term availability and supply chain stability compared to the obsolete URZ1H010MDD and 517D105M050JA6AE3.

Compliance Certification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements.

Physical Envelope Consideration: Substitute parts exhibit increased seated heights (11.00 mm to 13.00 mm) compared to the original (10.50 mm). PCB layout verification is required to confirm clearance in confined spaces.

Lifetime Enhancement: The 517D105M050JA6AE3 and SEK010M050ST offer extended lifetime ratings of 2000 hours at 105°C, providing improved reliability margins over the original 1000-hour specification.

Frequently Asked Questions (FAQ)

Q: Can I use these substitute parts interchangeably with the URZ1H010MDD?

A: Yes. All three substitute parts meet the core electrical parameters (1 µF, ±20%, 50 V) and mechanical specifications (lead spacing, diameter, through-hole mounting, radial can package) required for direct substitution. PCB layout must accommodate the increased physical heights of substitute parts.

Q: Why do substitute parts have different heights?

A: Radial aluminum electrolytic capacitors in the same case diameter may vary in height due to manufacturing tolerances and internal construction differences between manufacturers. The 0.079" (2.00 mm) lead spacing and 0.197" (5.00 mm) diameter remain constant across all parts, ensuring footprint compatibility on PCBs designed for through-hole mounting.

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

A: EKMG500ELL1R0ME11D or SEK010M050ST are recommended for new designs due to active product status, ensuring long-term availability and supply chain continuity. Both parts offer equivalent electrical performance and improved lifetime ratings.

Q: Are there compliance differences between the main part and substitutes?

A: No. All parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the impact of different lifetime ratings?

A: The original URZ1H010MDD and EKMG500ELL1R0ME11D are rated for 1000 hours at 105°C, while 517D105M050JA6AE3 and SEK010M050ST are rated for 2000 hours at 105°C. Higher lifetime ratings indicate extended operational reliability under thermal stress, though all parts operate within the same temperature range (-55°C to 105°C).
