Engineering Selection Recommendations

UPT2P271MHD6 (Nichicon): This part is a direct equivalent substitute with identical electrical specifications and compliance certifications. The primary difference is physical dimension variation (0.709" diameter vs. 0.630" diameter) and reduced height (1.457" vs. 1.634"). This substitute is suitable when PCB layout accommodates the larger radial can diameter. Both parts maintain ROHS3 compliance and identical voltage, capacitance, and ripple current ratings.

EKXJ251ELL271ML40S (Chemi-Con): This part represents an upgraded alternative with enhanced performance characteristics. It provides 250 V rated voltage (30 V higher than the original specification), extended lifetime of 12000 hours at 105°C (2.4× longer), and increased ripple current capacity (1.285 A @ 120 Hz and 2.89125 A @ 100 kHz). The operating temperature range extends to -40°C, providing broader environmental tolerance. This substitute is suitable for applications requiring improved reliability, extended service life, or higher voltage margin. The physical dimensions match the original part exactly (0.630" diameter, 1.634" height). AEC-Q200 automotive qualification is available on this part.

Frequently Asked Questions (FAQ)

Q: Can UPT2P271MHD6 be used as a direct drop-in replacement for UPT2P271MHD?

A: UPT2P271MHD6 is electrically equivalent with identical capacitance, voltage, tolerance, and ripple current specifications. However, the physical dimensions differ: the can diameter is 0.709" (18.00 mm) compared to 0.630" (16.00 mm) on the original part. Verify PCB layout clearance before substitution.

Q: What are the advantages of using EKXJ251ELL271ML40S over the original UPT2P271MHD?

A: EKXJ251ELL271ML40S provides three key improvements: 30 V higher voltage rating (250 V vs. 220 V), 2.4× longer operational lifetime (12000 hours vs. 5000 hours at 105°C), and significantly higher ripple current capacity. The extended temperature range (-40°C to 105°C) supports broader environmental applications. Physical dimensions are identical to the original part.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. UPT2P271MHD, UPT2P271MHD6, and EKXJ251ELL271ML40S are all ROHS3 compliant and REACH unaffected.

Q: What is the lead spacing requirement for PCB design?

A: All three parts maintain 0.295" (7.50 mm) lead spacing, ensuring consistent PCB footprint compatibility across substitutes.

Q: Can EKXJ251ELL271ML40S be used in applications originally designed for 220 V rated capacitors?

A: Yes. The 250 V rating on EKXJ251ELL271ML40S exceeds the 220 V requirement, providing additional voltage margin. This substitution is electrically compatible and does not require circuit redesign.

Q: What is the physical footprint difference between UPT2P271MHD and UPT2P271MHD6?

A: Both parts have identical lead spacing (7.50 mm). The can diameter differs: UPT2P271MHD is 0.630" (16.00 mm), while UPT2P271MHD6 is 0.709" (18.00 mm). Height also differs: 1.634" (41.50 mm) vs. 1.457" (37.00 mm). Verify PCB layout clearance for the larger diameter variant.
