Substitute Part Grouping Explanation

Substitute parts for the URS1J331MHD are qualified based on the following criteria:

Capacitance value: 330 µF (exact match required)
Voltage rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime specification: 2000 Hrs @ 85°C (exact match required)
Operating temperature range: -40°C ~ 85°C (exact match required)
Polarization: Polar (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial, Can (exact match required)
Lead spacing: 0.197" (5.00 mm) (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)

All identified substitutes meet these core electrical and mechanical parameters. Variations in physical dimensions (diameter and height) and ripple current ratings are permitted within the scope of this product category, provided all primary specifications remain unchanged.

Engineering Selection Recommendations

For new designs, the Panasonic ECA-1JM331 and ECA-1JM331B are preferred substitutes. Both parts carry Active product status and are ROHS3 compliant. The ECA-1JM331B is available in Cut Tape packaging, while ECA-1JM331 is supplied in Bulk packaging.

The Nichicon UVR1J331MPD is marked as Not For New Designs and should not be selected for new applications.

The Chemi-Con ESMG630ELL331MJ20S is discontinued at DiGi Electronics and is not recommended for new designs.

All substitute parts maintain full compliance with ROHS3 and REACH requirements. Physical dimension variations exist between the main part and substitutes; PCB layout verification is necessary to confirm mechanical fit within the available board space.

Frequently Asked Questions (FAQ)

Q: Can the UVR1J331MPD be used as a substitute for the URS1J331MHD?

A: The UVR1J331MPD meets all electrical and mechanical specifications for substitution. However, it is marked as Not For New Designs. Use only in legacy or maintenance applications where the original part is no longer available.

Q: What is the difference between ECA-1JM331 and ECA-1JM331B?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: ECA-1JM331 is supplied in Bulk, while ECA-1JM331B is supplied in Cut Tape (CT). Selection depends on procurement and assembly requirements.

Q: Are there physical dimension differences between the main part and substitutes?

A: Yes. The URS1J331MHD has a diameter of 0.492" (12.50 mm) and height of 0.650" (16.50 mm). All substitute parts have a diameter of 0.394" (10.00 mm) and heights ranging from 0.846" to 0.866" (21.50 mm to 22.00 mm). Verify PCB layout and available mounting space before substitution.

Q: Do all parts meet the same ripple current specifications?

A: No. The URS1J331MHD and ESMG630ELL331MJ20S support 1.065 A ripple current at high frequency. The Panasonic parts (ECA-1JM331 and ECA-1JM331B) support 935 mA, and the Nichicon UVR1J331MPD supports 816.5 mA at 10 kHz. Verify ripple current requirements in the application circuit before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant and REACH unaffected.
