URZ1E331MPD1TD Equivalent & Substitute Parts

Part Overview

The URZ1E331MPD1TD is a 330 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part is designed for general-purpose applications requiring through-hole mounting with a 1000-hour lifetime rating at 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the URZ1E331MPD1TD is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: Minimum 25 V (equal or higher acceptable)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Package Type: Radial, Can through-hole (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

The ECA-1VHG331 from Panasonic Electronic Components meets all substitution criteria. While it features a higher voltage rating (35 V) and extended lifetime (2000 Hrs @ 105°C), these represent improvements over the original specification and do not compromise compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

The ECA-1VHG331 is a direct functional substitute for the URZ1E331MPD1TD. Both components maintain ROHS3 compliance and are suitable for general-purpose applications. The substitute part offers extended operational lifetime (2000 Hrs @ 105°C versus 1000 Hrs @ 105°C) and higher voltage rating (35 V versus 25 V), providing improved reliability margins without altering circuit performance.

The primary design consideration is the increased height of the ECA-1VHG331 (0.531" maximum versus 0.413" maximum). PCB layout verification is necessary to confirm clearance in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the ECA-1VHG331 be used as a direct replacement for the URZ1E331MPD1TD?

A: Yes. Both components share identical capacitance (330 µF), tolerance (±20%), lead spacing (5.00 mm), and operating temperature range (-55°C ~ 105°C). The substitute part meets all electrical and mechanical requirements for direct substitution.

Q: What is the impact of the higher voltage rating on the ECA-1VHG331?

A: The 35 V rating on the substitute part exceeds the original 25 V specification. This provides additional voltage margin and does not negatively affect circuit operation. The component will function correctly in applications designed for 25 V operation.

Q: Does the increased height of the ECA-1VHG331 affect compatibility?

A: The substitute part is 0.118" (3.00 mm) taller than the original. PCB layout must be reviewed to confirm adequate clearance above the component. If space constraints exist, alternative solutions may be required.

Q: Are both parts RoHS compliant?

A: Yes. Both the URZ1E331MPD1TD and ECA-1VHG331 are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the URZ1E331MPD1TD classified as obsolete?

A: The original Nichicon part is no longer in active production. The ECA-1VHG331 from Panasonic is actively manufactured and stocked, providing reliable long-term availability for new designs and production continuity.
