Substitute Part Grouping Explanation

Substitution for the UHD1C152MHD1TO is determined by strict equivalence across the following critical parameters:

Capacitance: 1500 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 5000 Hrs @ 105°C (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required for PCB compatibility)
Case Diameter: 0.492" (12.50 mm) (exact match required for mechanical fit)
Mounting Type: Through Hole, Radial (exact match required)
Polarization: Polar (exact match required)

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the original component.

Engineering Selection Recommendations

Both substitute parts are suitable replacements based on the following criteria:

EKZE160ETD152MK20S (Chemi-Con KZE Series) is a direct manufacturer equivalent with Active product status. This part maintains identical electrical specifications and mechanical dimensions to the original UHD1C152MHD1TO. The slightly reduced seated height (21.50 mm vs. 22.00 mm) provides additional clearance margin in space-constrained applications. ROHS3 compliance and EAR99 classification match the original component.

EEU-FM1C152B (Panasonic FM-A Series) is a parametric equivalent with Active product status. This part meets all critical substitution criteria with identical capacitance, voltage, tolerance, and thermal specifications. The lower impedance (18 mOhms vs. 21 mOhms) and higher ripple current capability at 100 kHz (2.6 A vs. 2.36 A) represent performance improvements. ROHS3 compliance and EAR99 classification are maintained.

Both parts are REACH Compliant or REACH Unaffected, ensuring regulatory compatibility in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can EKZE160ETD152MK20S and EEU-FM1C152B be used interchangeably with UHD1C152MHD1TO?

A: Yes. Both substitute parts meet all critical electrical and mechanical parameters: 1500 µF capacitance, 16 V voltage rating, ±20% tolerance, 5000 Hrs @ 105°C lifetime, -40°C to 105°C operating range, 0.197" lead spacing, 0.492" case diameter, and through-hole radial mounting. PCB layout and circuit performance remain unchanged.

Q: What is the difference in seated height between the substitutes?

A: The EKZE160ETD152MK20S has a maximum seated height of 0.846" (21.50 mm), while both the UHD1C152MHD1TO and EEU-FM1C152B are 0.866" (22.00 mm). This 0.02" difference is within typical PCB design tolerances and does not affect mechanical compatibility.

Q: Do the impedance differences affect circuit performance?

A: The impedance values (21 mOhms for UHD1C152MHD1TO and EKZE160ETD152MK20S, 18 mOhms for EEU-FM1C152B) are within the normal range for this capacitor class. Selection should be based on circuit requirements; lower impedance may provide marginal benefits in high-frequency ripple filtering applications.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Which substitute should I choose for new procurement?

A: Both EKZE160ETD152MK20S and EEU-FM1C152B carry Active product status, indicating ongoing manufacturer support and availability. Selection between them should be based on supply chain availability, cost, and any specific performance requirements related to impedance or ripple current handling in your application.
