Substitute Part Grouping Explanation

Substitution for the UPB2D271MHD is determined by the following critical parameters: capacitance value (270 µF), voltage rating (200 V or higher), tolerance (±20%), package type (radial, can), lead spacing (7.50mm), physical dimensions, and through-hole mounting compatibility.

Substitute parts are grouped into two categories:

Direct Equivalents maintain identical electrical specifications and physical dimensions:

UCY2D271MHD6 (Nichicon UCY series)
UPT2D271MHD6 (Nichicon UPT series)

Similar Equivalents maintain core electrical specifications with minor dimensional variations:

UPT2D271MHD (Nichicon UPT series)

Higher Voltage Alternative provides equivalent capacitance and package with elevated voltage rating:

EKXJ221ELL271MMN3S (Chemi-Con KXJ series, 220 V rating)

Engineering Selection Recommendations

UCY2D271MHD6 is the preferred direct substitute. It maintains identical electrical specifications and physical dimensions as the UPB2D271MHD while offering extended lifetime (12000 hours at 105°C), expanded operating temperature range (-40°C to 105°C), and active product status. This part is ROHS3 compliant and provides superior reliability for new designs.

UPT2D271MHD6 serves as an alternative direct equivalent with identical dimensions and electrical ratings. It maintains 5000-hour lifetime specification and is ROHS3 compliant with active status.

UPT2D271MHD is functionally equivalent with identical electrical specifications but features reduced diameter (16.00mm vs 18.00mm) and increased height (37.00mm vs 33.00mm). This dimensional variation requires PCB layout verification before implementation.

EKXJ221ELL271MMN3S provides a higher voltage alternative (220 V vs 200 V) suitable for applications requiring increased voltage margin. This Chemi-Con part offers 12000-hour lifetime and extended temperature range (-40°C to 105°C). It carries AEC-Q200 automotive qualification and is ROHS3 compliant. Selection of this part is appropriate only when the higher voltage rating does not conflict with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can UCY2D271MHD6 be used as a direct replacement for UPB2D271MHD?

A: Yes. UCY2D271MHD6 maintains identical capacitance (270 µF), voltage rating (200 V), tolerance (±20%), package type (radial, can), lead spacing (7.50mm), and physical dimensions (0.709" diameter, 1.299" height). No PCB modifications are required.

Q: What is the primary advantage of UCY2D271MHD6 over the original UPB2D271MHD?

A: UCY2D271MHD6 provides extended lifetime (12000 hours at 105°C vs 5000 hours), expanded operating temperature range (-40°C to 105°C vs -25°C to 105°C), and active product status with ROHS3 compliance.

Q: Can UPT2D271MHD be used as a substitute despite dimensional differences?

A: UPT2D271MHD is electrically equivalent but features different physical dimensions (0.630" diameter, 1.457" height vs 0.709" diameter, 1.299" height). PCB layout verification is required to confirm the larger height does not create clearance conflicts.

Q: When should EKXJ221ELL271MMN3S be selected?

A: EKXJ221ELL271MMN3S is appropriate when the circuit design permits the higher 220 V voltage rating and when automotive-grade qualification (AEC-Q200) or extended temperature operation (-40°C to 105°C) is required.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitute parts are through-hole mounted with 7.50mm lead spacing, maintaining compatibility with existing PCB designs.

Q: What compliance certifications apply to the substitute parts?

A: UCY2D271MHD6, UPT2D271MHD6, UPT2D271MHD, and EKXJ221ELL271MMN3S are all ROHS3 compliant. EKXJ221ELL271MMN3S additionally carries AEC-Q200 automotive qualification.
