Equivalent & Substitute Parts for URY1J331MHD

Part Overview

The URY1J331MHD is a 330 µF, 63 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as obsolete, with a rated lifetime of 2000 hours at 105°C. Due to its obsolete status, equivalent and substitute parts from active or not-for-new-designs product lines are necessary for ongoing system support and new design implementations. Substitute parts maintain the core electrical specifications while offering improved performance characteristics or extended availability through alternative series.

Engineering Selection Recommendations

For Direct Form Factor Replacement (Identical Lead Spacing and Diameter):

UPJ1J331MHD6 and UPM1J331MHD6 maintain the original 0.295" (7.50mm) lead spacing and 0.709" (18.00mm) diameter. These parts provide extended lifetime (5000 hours at 105°C) compared to the original 2000-hour rating. UPM1J331MHD6 includes AEC-Q200 automotive qualification.

For General Purpose Applications with Extended Availability:

UPW1J331MHD offers the highest lifetime rating (7000 hours at 105°C) with active inventory of 12,817 units. This part requires PCB layout adjustment due to 0.197" (5.00mm) lead spacing and 0.492" (12.50mm) diameter.

For Active Product Status:

URZ1J331MHD maintains active product status with 5,856 units in inventory. This part operates at 1000-hour lifetime at 105°C, lower than the original specification, and requires lead spacing and diameter adjustment.

For Alternative Manufacturer with Highest Inventory:

ECA-1JHG331 (Panasonic NHG-A series) is the only active alternative manufacturer option with 72,555 units in stock. This part matches the 2000-hour lifetime specification and requires identical PCB layout modifications as other 0.197" lead spacing parts.

Frequently Asked Questions (FAQ)

Q: Can URY1J331MHD be directly replaced with UPJ1J331MHD6 without PCB modification?

A: Yes. UPJ1J331MHD6 maintains identical lead spacing (0.295" / 7.50mm) and diameter (0.709" / 18.00mm) as the original URY1J331MHD. Physical footprint compatibility is confirmed.

Q: What is the difference between UPM1J331MHD and UPM1J331MHD6?

A: Both parts are Nichicon UPM series with identical electrical specifications (330 µF, 63 V, ±20%, 5000 Hrs @ 105°C). UPM1J331MHD6 features 0.295" (7.50mm) lead spacing and 0.709" (18.00mm) diameter, while UPM1J331MHD uses 0.197" (5.00mm) lead spacing and 0.492" (12.50mm) diameter. UPM1J331MHD6 provides direct form factor compatibility with URY1J331MHD.

Q: Why does ECA-1JHG331 have significantly higher inventory than Nichicon alternatives?

A: ECA-1JHG331 maintains active product status, whereas most Nichicon substitutes are classified as "Not For New Designs." Active products typically maintain higher stock levels for ongoing market demand.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications with the original URY1J331MHD.

Q: Which substitute offers the best lifetime performance?

A: UPW1J331MHD provides 7000 hours at 105°C, the highest among all substitutes. This represents a 4.6x improvement over the original 2000-hour specification. PCB layout modification is required due to different lead spacing and diameter.

Q: Can parts with different lead spacing be used interchangeably?

A: No. Parts with 0.197" (5.00mm) lead spacing (UPJ1J331MHD, UPM1J331MHD, UPS1J331MHD, UPW1J331MHD, UVY1J331MPD, UVZ1J331MPD, ECA-1JHG331) require PCB layout modification compared to the original 0.295" (7.50mm) spacing. Parts with matching 0.295" spacing (UPJ1J331MHD6, UPM1J331MHD6) are direct replacements.

Q: What is the significance of AEC-Q200 rating on UPM1J331MHD and UPM1J331MHD6?

A: AEC-Q200 certification indicates automotive-grade qualification. These parts meet additional reliability and testing requirements for automotive applications. This rating is not present on other substitute options.
