Equivalent & Substitute Parts for UES1C102MHM

Part Overview

The UES1C102MHM is a 1000 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 1000 hours at 85°C and is designed for audio applications. The part carries a "Not For New Designs" product status, indicating that Nichicon has discontinued active development for this series. Finding equivalent or substitute parts is necessary for ongoing maintenance, repair, and legacy system support where the original specification must be maintained or improved.

Substitute Part Grouping Explanation

Substitution for the UES1C102MHM is determined by the following critical parameters:

Capacitance Value: Must be 1000 µF (exact match required)
Voltage Rating: Minimum 16 V; higher ratings are acceptable as direct substitutes
Tolerance: ±20% (standard for this capacitor class)
Package Geometry: Radial, can configuration with 0.295" (7.50 mm) lead spacing
Mounting Type: Through hole only
Polarization: Bi-polar configuration

The substitute parts UEP1E102MHD and UVP1E102MHD meet all mechanical and electrical compatibility requirements. Both parts maintain identical capacitance, tolerance, lead spacing, and mounting type. The voltage rating is increased to 25 V, which is a direct upgrade and does not compromise circuit compatibility. Both substitutes are manufactured by Nichicon and maintain the same package footprint.

Engineering Selection Recommendations

Both UEP1E102MHD and UVP1E102MHD are direct substitutes for UES1C102MHM based on electrical and mechanical compatibility. Selection between the two substitutes depends on application requirements:

UEP1E102MHD provides an extended operating temperature range (-55°C to 105°C) and maintains ROHS3 compliance with REACH unaffected status. This part is suitable for applications requiring broader temperature performance.

UVP1E102MHD offers extended lifetime (2000 hours at 85°C versus 1000 hours) and higher ripple current ratings (950 mA @ 120 Hz and 1.0925 A @ 10 kHz). This part is suitable for applications with sustained thermal stress or higher ripple current demands. Note that this part carries REACH affected status.

Both substitutes maintain the same physical footprint and lead spacing as the original UES1C102MHM, ensuring direct board-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can UEP1E102MHD or UVP1E102MHD be used as direct replacements for UES1C102MHM?

A: Yes. Both parts maintain identical capacitance (1000 µF), tolerance (±20%), lead spacing (0.295" / 7.50 mm), and package type (radial, can). The increased voltage rating (25 V versus 16 V) is a direct upgrade and does not affect circuit compatibility.

Q: What is the difference between UEP1E102MHD and UVP1E102MHD?

A: UEP1E102MHD extends the operating temperature range to -55°C ~ 105°C and maintains 1000-hour lifetime at 105°C. UVP1E102MHD extends the lifetime to 2000 hours at 85°C and provides higher ripple current ratings. UVP1E102MHD carries REACH affected status, while UEP1E102MHD does not.

Q: Will the substitute parts fit the same PCB footprint?

A: Yes. Both UEP1E102MHD and UVP1E102MHD maintain the same lead spacing (0.295" / 7.50 mm), diameter (0.630" / 16.00 mm), and through-hole mounting configuration. The maximum seated height increases slightly (1.063" versus 1.043"), but this remains within standard component clearance tolerances for radial capacitors.

Q: Are there any compliance differences between the original and substitute parts?

A: All three parts are ROHS3 compliant. UES1C102MHM and UEP1E102MHD are REACH unaffected. UVP1E102MHD is REACH affected. Verify REACH compliance requirements for your specific application before selection.

Q: What is the significance of the "Not For New Designs" status?

A: This status indicates that Nichicon has discontinued active development for the UES series. The substitute parts (UEP and UVP series) represent current production alternatives with equivalent or improved specifications, making them suitable for both legacy system maintenance and new applications.
