Equivalent & Substitute Parts for UPJ2A151MHD1TO

Part Overview

The UPJ2A151MHD1TO is a 150 µF, 100 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is classified as Not For New Designs. Due to this product status and the need for design flexibility, equivalent and substitute parts are available from both Nichicon and alternative manufacturers that maintain electrical and mechanical compatibility within the specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Electrical Parameters: Capacitance (150 µF), tolerance (±20%), and rated voltage (100 V) must be identical
Mechanical Compatibility: Lead spacing (5.00mm), package type (Radial, Can), and mounting type (Through Hole) must match
Environmental Specifications: Operating temperature range (-55°C ~ 105°C) and polarization (Polar) must be maintained
Compliance: RoHS3 compliance is required for all substitutes

Substitute parts are grouped into two categories:

Direct Equivalents maintain all electrical and mechanical parameters with identical or equivalent lifetime ratings (5000 Hrs @ 105°C). These include UPJ2A151MHD (Bulk packaging), UPM2A151MHD1TO (Automotive-rated), and EEU-FC2A151B (Panasonic alternative).

Upgraded Alternatives provide enhanced performance characteristics while maintaining core compatibility. UPW2A151MHD1TO offers extended lifetime (7000 Hrs @ 105°C) and represents a performance upgrade option.

Engineering Selection Recommendations

For Direct Replacement: UPJ2A151MHD (Bulk packaging) provides identical electrical and mechanical specifications with the same product status classification. This option is suitable for applications where packaging format flexibility is acceptable.

For Automotive Applications: UPM2A151MHD1TO is qualified to AEC-Q200 standards and carries automotive ratings. This part is appropriate for automotive-grade designs requiring enhanced ripple current performance (780 mA @ 120 Hz, 1.12 A @ 10 kHz).

For Extended Lifetime Requirements: UPW2A151MHD1TO offers 7000 hours at 105°C, providing 40% longer operational life compared to the base specification. This upgrade is suitable for applications with extended service life requirements.

For Active Product Status: EEU-FC2A151B from Panasonic is the only substitute with Active product status. This part is recommended for new design initiatives and long-term supply chain planning. It carries AEC-Q200 automotive qualification and is ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can UPJ2A151MHD1TO be replaced with UPJ2A151MHD?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: UPJ2A151MHD1TO is supplied in Cut Tape (CT), while UPJ2A151MHD is supplied in Bulk. Lead spacing, capacitance, voltage rating, and lifetime specifications are identical.

Q: What is the difference between UPM2A151MHD1TO and UPJ2A151MHD1TO?

A: UPM2A151MHD1TO is automotive-qualified (AEC-Q200) with enhanced ripple current ratings (780 mA @ 120 Hz, 1.12 A @ 10 kHz versus 553 mA @ 120 Hz, 798 mA @ 10 kHz). Physical dimensions differ slightly in height (27.00mm versus 26.50mm). Both maintain 5000-hour lifetime at 105°C.

Q: Is UPW2A151MHD1TO a direct substitute?

A: UPW2A151MHD1TO is a compatible upgrade, not a direct substitute. It provides extended lifetime (7000 Hrs @ 105°C) and slightly higher impedance (130 mOhms versus 110 mOhms). Height is 27.00mm versus 26.50mm. Electrical parameters (capacitance, voltage, tolerance) remain identical.

Q: Why is EEU-FC2A151B recommended for new designs?

A: EEU-FC2A151B carries Active product status, ensuring long-term availability and supply chain stability. It is manufactured by Panasonic, providing design diversification. AEC-Q200 automotive qualification and ROHS3 compliance are maintained.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, meeting environmental and regulatory requirements.

Q: What is the maximum height variation among substitutes?

A: Maximum height variation is 0.50mm (26.50mm for UPJ2A151MHD1TO versus 27.00mm for UPM2A151MHD1TO, UPW2A151MHD1TO, and EEU-FC2A151B). PCB layout and clearance verification is recommended when substituting between these groups.
