Substitute Part Grouping Explanation

Substitution for the UPJ1E331MPD1TA is determined by strict equivalence in the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 3000 Hrs @ 105°C (exact match required)
Operating Temperature: -55°C ~ 105°C (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
RoHS Compliance: ROHS3 Compliant (exact match required)

Substitute parts are grouped into two categories:

Parametric Equivalent: UPJ1E331MPD1TD (Nichicon) — identical electrical and mechanical specifications with different packaging format (Cut Tape vs. alternative tape configuration).

Upgrade Substitutes: ELXV250EC3331MH20D, ELXV250ETC331MH20D, ELXV250ETD331MH20D, and ELXY250ETC331MH20D (Chemi-Con LXV and LXY series) — meet all core electrical parameters and are rated Active with AEC-Q200 automotive qualification. Minor variations exist in ripple current performance and lead spacing for the LXY series variant.

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer): UPJ1E331MPD1TD is the parametric equivalent within the Nichicon UPJ series. Both components share identical electrical specifications and are classified as "Not For New Designs." This option is suitable for legacy system maintenance where manufacturer continuity is required.

For Active Product Line Substitution: The Chemi-Con LXV series (ELXV250EC3331MH20D, ELXV250ETC331MH20D, ELXV250ETD331MH20D) provides upgrade substitutes with Active product status and AEC-Q200 automotive qualification. These parts meet all core electrical parameters and offer improved impedance performance (110 mOhms vs. 130 mOhms). The primary consideration is lead spacing compatibility (4.60mm standard) and packaging format selection (Tape & Reel or Cut Tape).

For Enhanced Performance: ELXY250ETC331MH20D (Chemi-Con LXY series) offers the lowest impedance (95 mOhms) and highest ripple current capability at high frequency (740 mA @ 100 kHz). This variant uses 5.00mm lead spacing and requires PCB layout verification before implementation.

Compliance Consideration: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original component's regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can UPJ1E331MPD1TD be used as a direct replacement for UPJ1E331MPD1TA?

A: Yes. UPJ1E331MPD1TD is a parametric equivalent with identical electrical and mechanical specifications. The difference is packaging format (tape configuration). Both are Nichicon UPJ series components rated "Not For New Designs."

Q: What is the difference between the Chemi-Con LXV and LXY series substitutes?

A: Both series meet the core electrical requirements (330 µF, 25 V, ±20%, 3000 Hrs @ 105°C). The LXY series (ELXY250ETC331MH20D) provides lower impedance (95 mOhms vs. 110 mOhms) and higher ripple current at high frequency (740 mA @ 100 kHz vs. 640 mA @ 100 kHz). The LXY variant uses 5.00mm lead spacing instead of 4.60mm, requiring PCB layout verification.

Q: Are the Chemi-Con substitutes suitable for automotive applications?

A: Yes. All Chemi-Con LXV and LXY series substitutes carry AEC-Q200 automotive qualification and are rated for automotive applications. The original UPJ1E331MPD1TA is rated for general purpose applications only.

Q: What packaging options are available for substitutes?

A: Parametric equivalent UPJ1E331MPD1TD is available in Cut Tape (CT). Chemi-Con upgrades are available in both Tape & Reel (TR) and Cut Tape (CT) formats. Verify packaging compatibility with your procurement and assembly processes.

Q: Does lead spacing differ between substitutes?

A: Most substitutes maintain 4.60mm lead spacing (ELXV series and UPJ1E331MPD1TD). The ELXY250ETC331MH20D uses 5.00mm lead spacing. Verify PCB hole spacing before selecting this variant.

Q: Are there inventory considerations for these substitutes?

A: Current inventory levels vary: UPJ1E331MPD1TA (857 Pcs), UPJ1E331MPD1TD (2890 Pcs), ELXV250EC3331MH20D (639 Pcs), ELXV250ETC331MH20D (1023 Pcs), ELXV250ETD331MH20D (988 Pcs), ELXY250ETC331MH20D (1081 Pcs). Verify availability with your supplier for production requirements.
