Engineering Selection Recommendations

For Direct Replacement (Same Electrical and Mechanical Specifications):

EKZE160ELL102MJ20S (Chemi-Con) and ESY108M016AH4AA (KEMET) are the closest direct substitutes. Both maintain 1000 µF capacitance, 16 V rating, 4000 hour lifetime at 105°C, and identical lead spacing and diameter. Both manufacturers hold Active product status, ensuring continued availability and support. EKZE160ELL102MJ20S exhibits impedance and ripple current characteristics nearly identical to the original UHD1C102MPD. ESY108M016AH4AA provides specified ESR of 26 mOhm at 100 kHz with matching ripple current performance.

For Improved Performance with Same Footprint:

EEU-FM1C102 (Panasonic Electronic Components) offers superior electrical performance within the same physical envelope. It maintains 1000 µF, 16 V, and identical lead spacing and diameter, but provides lower impedance (19 mOhms), higher ripple current capability (1.635 A @ 120 Hz, 2.18 A @ 100 kHz), and 5000 hour lifetime. Active product status ensures long-term availability.

For Voltage Margin Enhancement:

UHW1E102MPD (Nichicon) provides 25 V rating with 1000 µF capacitance, offering voltage headroom for applications requiring additional safety margin. It delivers extended 10000 hour lifetime at 105°C and improved electrical characteristics (19 mOhms impedance, 2.5 A ripple current @ 100 kHz). Physical dimensions remain compatible with the original footprint.

For Active Product Status with Equivalent Specifications:

UPA1C102MPD3 (Nichicon) is the only Nichicon part with Active product status matching the original 1000 µF, 16 V, 4000 hour specification. It maintains identical lead spacing and diameter, though impedance is higher at 35 mOhms and ripple current capability is reduced. This part ensures manufacturer support and continued production.

Compliance Considerations:

All substitute parts listed maintain ROHS3 compliance. EEU-FM1C102 and EKZE160ELL102MJ20S carry REACH Unaffected status, while most Nichicon parts are REACH Affected. All parts are classified under ECCN EAR99 and HTSUS 8532.22.0020.

Frequently Asked Questions (FAQ)

Q: Can UHW1E102MPD be used as a direct replacement for UHD1C102MPD?

A: UHW1E102MPD is electrically compatible as a substitute. It maintains 1000 µF capacitance and identical lead spacing (0.197", 5.00mm) and diameter (0.394", 10.00mm). The 25 V rating exceeds the 16 V requirement, providing voltage margin. Physical dimensions are identical, allowing direct PCB mounting. The higher voltage rating and extended 10000 hour lifetime represent performance improvements. No circuit modification is required.

Q: What is the difference between UHE1C102MPD and UHV1C102MPD?

A: Both are 1000 µF, 16 V Nichicon capacitors with identical lead spacing and diameter. UHE1C102MPD offers 7000 hour lifetime at 105°C with 46 mOhms impedance and 0.787" height. UHV1C102MPD provides 6000 hour lifetime with 30 mOhms impedance and 0.689" height. UHE1C102MPD is preferred for applications requiring extended operational life, while UHV1C102MPD offers a more compact vertical profile. Both are Not For New Designs.

Q: Is UHV1C102MPD6 compatible with the original UHD1C102MPD footprint?

A: UHV1C102MPD6 maintains the same 1000 µF, 16 V electrical specification and height (0.866", 22.00mm) as the original. However, the lead spacing is 0.138" (4.60mm) versus the original 0.197" (5.00mm), and the diameter is 0.315" (8.00mm) versus 0.394" (10.00mm). This part is not a direct PCB replacement due to different lead pitch and smaller diameter. It is suitable only for new designs with modified PCB layouts.

Q: Which substitute offers the best electrical performance?

A: EEU-FM1C102 (Panasonic) delivers the lowest impedance at 19 mOhms and highest ripple current capability (1.635 A @ 120 Hz, 2.18 A @ 100 kHz) while maintaining identical physical dimensions and lead spacing. It is Active status and suitable for applications requiring superior high-frequency performance and thermal stability.

Q: Are there any lead spacing or diameter restrictions when selecting a substitute?

A: Yes. The original UHD1C102MPD specifies 0.197" (5.00mm) lead spacing and 0.394" (10.00mm) diameter. Direct PCB replacements must maintain these dimensions. EKZE160ELL102MJ20S, ESY108M016AH4AA, EEU-FM1C102, UHW1E102MPD, UPA1C102MPD3, UHE1C102MPD, and UHV1C102MPD all meet these requirements. UHE1C102MHD6 has different diameter (0.492", 12.50mm) and height (0.591", 15.00mm), and UHV1C102MPD6 has different lead spacing (0.138", 4.60mm) and diameter (0.315", 8.00mm), making them unsuitable for direct replacement.

Q: What is the significance of Product Status (Active vs. Not For New Designs)?

A: Active status indicates the manufacturer continues production and provides full technical support. Not For New Designs indicates the part is obsolete in the manufacturer's current lineup but may remain available from inventory. For new designs, select Active parts: UPA1C102MPD3, EEU-FM1C102, EKZE160ELL102MJ20S, ESY108M016AH4AA, or 108KBM016M. For legacy system maintenance, Not For New Designs parts remain viable if inventory is available.

Q: How do ripple current ratings affect component selection?

A: Ripple current rating determines the maximum AC current the capacitor can safely handle at specified frequencies. The original UHD1C102MPD handles 1.365 A @ 120 Hz and 1.82 A @ 100 kHz. Substitutes with equal or higher ripple current ratings are directly compatible. EEU-FM1C102 exceeds these values (1.635 A @ 120 Hz, 2.18 A @ 100 kHz), providing margin for high-ripple applications. Parts with lower ratings (UHE1C102MPD, UHV1C102MPD) may be unsuitable for high-current ripple environments.

Q: Can 108KBM016M replace UHD1C102MPD despite lower ripple current at 120 Hz?

A: 108KBM016M maintains 1000 µF, 16 V, identical lead spacing and diameter, and 4000 hour lifetime. However, it specifies only 840 mA ripple current @ 120 Hz versus the original 1.365 A. This part is suitable only for applications with lower ripple current demands. For circuits requiring the original ripple current specification, this substitute is not recommended.
