Engineering Selection Recommendations

Direct Nichicon Substitute: UHE1H272MHD is the closest equivalent within the same manufacturer series. It maintains identical electrical specifications and physical dimensions to the UHE1H272MHT while offering ROHS3 compliance. This part is suitable for applications where manufacturer continuity is preferred, though it carries a "Not For New Designs" status.

Active Chemi-Con Alternatives: EKYB500ELL272MMP1S, EKZN500ELL272MMP1S, EKY-500ELL272MM40S, and KY50VB272M18X40LL are all active production parts from Chemi-Con. All four meet the core electrical and mechanical substitution criteria. EKYB500ELL272MMP1S and EKZN500ELL272MMP1S offer reduced height (1.457" vs. 1.575"), which may provide PCB layout advantages in space-constrained designs. EKY-500ELL272MM40S and KY50VB272M18X40LL maintain the original height specification.

Compliance Considerations: EKYB500ELL272MMP1S, EKZN500ELL272MMP1S, and EKY-500ELL272MM40S are ROHS3 compliant, making them suitable for applications subject to RoHS regulations. KY50VB272M18X40LL is RoHS non-compliant and should be selected only when legacy compliance status is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different height dimensions? A: Height variations exist among the substitutes. EKYB500ELL272MMP1S and EKZN500ELL272MMP1S are 0.118" shorter (1.457" vs. 1.575"), while EKY-500ELL272MM40S is 0.059" taller (1.634" vs. 1.575"). Verify PCB layout clearance before selection. All other mechanical parameters remain identical.

Q: What is the difference between the Chemi-Con series options? A: EKYB500ELL272MMP1S (KYB series) and EKZN500ELL272MMP1S (KZN series) are functionally equivalent with identical dimensions and compliance status. EKY-500ELL272MM40S and KY50VB272M18X40LL are also equivalent to each other. Selection between series can be based on availability and inventory status.

Q: Are all substitutes electrically interchangeable? A: Yes. All substitutes maintain the same capacitance (2700 µF), voltage rating (50 V), tolerance (±20%), lifetime (10,000 Hrs @ 105°C), and operating temperature range (-40°C ~ 105°C). Ripple current and impedance variations are within acceptable ranges for general-purpose applications.

Q: Which substitute should I choose for new designs? A: For new designs, select from the active production parts: EKYB500ELL272MMP1S, EKZN500ELL272MMP1S, EKY-500ELL272MM40S, or KY50VB272M18X40LL. All are ROHS3 compliant except KY50VB272M18X40LL. Consider height constraints and availability when making the final selection.

Q: Is the UHE1H272MHD a direct replacement? A: UHE1H272MHD is a direct replacement from Nichicon with identical dimensions and electrical specifications. However, it carries a "Not For New Designs" status. It is suitable for legacy system maintenance and repair applications.
