UPS1J331MHD1TD Equivalent & Substitute Parts

Part Overview

The UPS1J331MHD1TD is a 330 µF, 63 V aluminum electrolytic capacitor manufactured by Nichicon in the UPS series. This radial, through-hole component is rated for 3000 hours at 105°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling. The main part is currently in active production status. Substitute parts become necessary when the original packaging format is unavailable, when inventory constraints exist, or when design flexibility allows for alternative packaging configurations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the UPS1J331MHD1TD is determined by strict equivalence across all critical electrical and mechanical parameters. The allowed substitute must maintain identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), thermal lifetime (3000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), ripple current specifications (695.8 mA @ 120 Hz and 980 mA @ 100 kHz), lead spacing (5.00 mm), case diameter (12.50 mm), height (22.00 mm), and mounting configuration (through-hole radial can).

The primary differentiator among equivalent parts is packaging format. The UPS1J331MHD1TD is supplied in Tape & Box (TB) configuration, while the substitute UPS1J331MHD1TO is supplied in Cut Tape (CT) configuration. Both parts are from the Nichicon UPS series and share identical electrical performance and physical dimensions. The packaging difference does not affect component functionality, electrical characteristics, or PCB mounting compatibility.

Engineering Selection Recommendations

The UPS1J331MHD1TD is the preferred selection for new designs due to its active product status. The substitute part UPS1J331MHD1TO carries a "Not For New Designs" status, indicating that Nichicon does not recommend its use in new product development. However, UPS1J331MHD1TO remains electrically and mechanically equivalent and may be used in legacy system maintenance, repair, or rework scenarios where the original part number is unavailable.

Selection between these parts should be based on availability and application context rather than electrical performance, as both components deliver identical functional specifications. The packaging format difference (Tape & Box versus Cut Tape) affects supply chain logistics and handling procedures but does not impact circuit performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can UPS1J331MHD1TO be used as a direct replacement for UPS1J331MHD1TD in new designs?

A: No. While UPS1J331MHD1TO is electrically and mechanically equivalent, Nichicon designates it as "Not For New Designs." New product development should use UPS1J331MHD1TD, which carries active product status.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging supplies components on continuous tape with a protective box, typically used for larger orders. Cut Tape packaging supplies components on tape segments, typically used for smaller quantities or mixed orders. Both formats contain identical components with no functional difference.

Q: Are the physical dimensions identical between UPS1J331MHD1TD and UPS1J331MHD1TO?

A: Yes. Both parts share identical lead spacing (5.00 mm), case diameter (12.50 mm), and seated height (22.00 mm). They are mechanically interchangeable on PCBs designed for radial through-hole capacitors with these specifications.

Q: Do both parts meet the same electrical specifications?

A: Yes. Both parts deliver 330 µF capacitance at 63 V with ±20% tolerance, 3000-hour lifetime at 105°C, identical ripple current ratings (695.8 mA @ 120 Hz and 980 mA @ 100 kHz), and the same operating temperature range (-55°C ~ 105°C).

Q: When should UPS1J331MHD1TO be considered?

A: UPS1J331MHD1TO may be used in repair, rework, or maintenance of existing systems where UPS1J331MHD1TD is temporarily unavailable, provided the application does not require active product status certification or long-term supply chain continuity.
