Equivalent & Substitute Parts for UPT2E151MHD

Part Overview

The UPT2E151MHD is a 150 µF, 250 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production status.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements demand extended operational lifetime, or when alternative manufacturers' components meet the same electrical and mechanical specifications for system compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the UPT2E151MHD is determined by the following critical parameters:

Electrical Equivalence: Capacitance value (150 µF), voltage rating (250 V), and tolerance (±20%) must match exactly
Thermal Performance: Operating temperature range (-25°C to 105°C) must be maintained
Mechanical Compatibility: Lead spacing (7.50 mm), mounting type (through hole), and package style (radial, can) must be compatible with PCB layout
Regulatory Compliance: RoHS3 compliance status must be maintained

The substitute parts listed below meet these core requirements. Variations in case diameter, height, ripple current ratings, and lifetime specifications are permitted when the above critical parameters are satisfied.

Engineering Selection Recommendations

Active Status Priority: The UPT2E151MHD maintains active production status. Selection of this part is recommended when availability and long-term supply continuity are design considerations.

Obsolete Part Handling: The substitute parts UCA2E151MHD, EEU-EB2E151, EEU-ED2E151, and EEU-EE2E151 are classified as obsolete. These parts are suitable for replacement in existing designs or legacy system support where inventory is available, but should not be selected for new designs requiring long-term component availability.

Compliance Verification: All listed parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Mechanical Fit Consideration: The UPT2E151MHD features a smaller case diameter (16.00 mm) compared to substitute parts (18.00 mm). PCB layout verification is required before substitution to confirm adequate clearance around the component footprint.

Frequently Asked Questions (FAQ)

Q: Can EEU-EB2E151 or EEU-ED2E151 be used as direct replacements for UPT2E151MHD?

A: Electrical substitution is valid. Both parts share identical capacitance (150 µF), voltage rating (250 V), tolerance (±20%), lead spacing (7.50 mm), and mounting type (through hole). However, the larger case diameter (18.00 mm versus 16.00 mm) requires PCB layout verification to confirm physical clearance.

Q: What is the difference between UCA2E151MHD and EEU-EE2E151?

A: Both parts meet the core electrical and mechanical substitution criteria. UCA2E151MHD is manufactured by Nichicon with 12000-hour lifetime rating. EEU-EE2E151 is manufactured by Panasonic with 10000-hour lifetime rating. Both are obsolete. Selection depends on inventory availability and application lifetime requirements.

Q: Are there any ripple current differences between the main part and substitutes?

A: Ripple current ratings vary across the part family. The UPT2E151MHD is rated for 620 mA at 120 Hz and 992 mA at 10 kHz. Substitute parts exhibit higher ripple current handling. These differences do not affect substitution eligibility when the primary electrical parameters match.

Q: Is the height difference between parts significant for PCB design?

A: Height variations range from 1.240" to 1.319" (31.50 mm to 34.60 mm). For applications with vertical space constraints, EEU-ED2E151 offers the minimum height. Verification against PCB clearance requirements is necessary before final part selection.

Q: Can I use EEU-EE2E151 in a new design?

A: EEU-EE2E151 is classified as obsolete. For new designs, the active-status UPT2E151MHD is the recommended selection to ensure long-term supply availability and manufacturing continuity.
