Engineering Selection Recommendations

For Direct Replacement (10V Rating):

UHE1A102MPD6 is the preferred direct equivalent, offering 6000-hour lifetime at 105°C with matching lead spacing (0.197", 5.00mm) and identical physical footprint (0.394" diameter, 0.630" height). This part maintains ROHS3 compliance and is available in high inventory (6786 pcs). UHV1A102MPD provides the most compact height option (0.551", 14.00mm) while maintaining identical electrical specifications and lead spacing.

For Upgraded Performance (16V Rating):

16ZLH1000MEFC10X16 from Rubycon is recommended for new designs requiring extended operational lifetime. This part delivers 10000-hour lifetime at 105°C with identical physical dimensions to the original UPB1A102MPD (0.394" diameter, 0.689" height, 0.197" lead spacing). The elevated 16 V rating provides enhanced design margin for applications with voltage transients or future specification changes. ROHS3 compliance and active product status ensure long-term availability.

UHW1C102MPD from Nichicon offers equivalent performance with 10000-hour lifetime and matching physical footprint, providing an alternative within the Nichicon product family.

For Space-Constrained Applications:

UHV1A102MPD (10V) or UHV1A102MPD6 (10V) accommodate reduced PCB height requirements with 0.551" and 0.650" seated heights respectively, while maintaining full electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can UHE1A102MPD6 directly replace UPB1A102MPD without PCB modification?

A: Yes. Both parts share identical lead spacing (0.197", 5.00mm), diameter (0.394", 10.00mm), and height (0.630" to 0.689" range). No PCB layout changes are required. The UHE1A102MPD6 provides improved 6000-hour lifetime versus the original 7000-hour specification, with ROHS3 compliance.

Q: What is the difference between 10V and 16V rated substitutes?

A: The 16V-rated parts (UHW1C102MPD, 16YXJ1000M10X16, 16ZLH1000MEFC10X16) provide higher voltage margin and extended 10000-hour lifetime at 105°C. These are electrically compatible in 10V applications and recommended for new designs. The elevated voltage rating does not affect circuit operation in 10V applications.

Q: Are there physical dimension differences between substitute options?

A: Yes. Parts with 0.197" (5.00mm) lead spacing maintain the original footprint. Parts with 0.138" (4.60mm) lead spacing require PCB modification. Height variations range from 0.551" to 0.866", affecting vertical clearance. Verify PCB layout constraints before selection.

Q: Which substitute offers the best long-term availability?

A: 16ZLH1000MEFC10X16 from Rubycon carries active product status with 8305 pcs in inventory and ROHS3 compliance, ensuring sustained availability. This part is suitable for new production designs requiring extended component lifecycle.

Q: Can UHD1A102MPD be used as a substitute despite lower lifetime rating?

A: UHD1A102MPD is electrically compatible but offers only 3000-hour lifetime at 105°C versus the original 7000 hours. This part is classified as not for new designs. Use only in legacy applications where lifetime requirements are reduced or in non-critical circuits.

Q: What compliance certifications apply to substitute parts?

A: All Nichicon substitutes (UHE, UHV, UHW series) and Rubycon substitutes (YXJ, ZLH series) carry ROHS3 compliance. REACH status varies: Nichicon UPB and Rubycon parts are REACH Unaffected; Nichicon UHD, UHE, UHV series are REACH Affected. Verify compliance requirements for your application jurisdiction.
