ECA-1JM330I Equivalent & Substitute Parts

Part Overview

The ECA-1JM330I is a 33 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production status with ROHS3 compliance.

Equivalent and substitute parts become necessary when the primary part number reaches end-of-life status, when packaging requirements differ (bulk versus cut tape), or when alternative manufacturers' components meet the same electrical and mechanical specifications for system compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ECA-1JM330I is determined by strict equivalence across the following parameters:

Capacitance: 33 µF (exact match required)
Voltage Rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.098" (2.50 mm) (exact match required)
Case Diameter: 0.248" (6.30 mm) (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in product status, lifetime ratings at different temperatures, ripple current specifications, and packaging formats (bulk versus cut tape) do not disqualify substitution when the above parameters align.

Engineering Selection Recommendations

Primary Substitute (Panasonic Series): ECA-1JM330 is the direct equivalent to ECA-1JM330I, differing only in packaging format (bulk versus individual packaging). Both parts are manufactured by Panasonic, share identical electrical specifications, and maintain active product status. Selection between these two depends on procurement quantity and assembly process requirements.

Alternative Substitutes (Nichicon Series): UVR1J330MED, UVR1J330MED1TD, UPS1J330MED1TD, and UPW1J330MED1TD are all Nichicon-manufactured alternatives that meet the core electrical and mechanical parameters. All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the primary part.

The Nichicon UVR series (UVR1J330MED and UVR1J330MED1TD) maintains identical operating temperature range (-40°C to 85°C) and lifetime rating (2000 Hrs @ 85°C) as the ECA-1JM330I. These parts are classified as obsolete but remain available in inventory.

The Nichicon UPS and UPW series (UPS1J330MED1TD and UPW1J330MED1TD) offer extended operating temperature range (-55°C to 105°C) and higher lifetime rating (2000 Hrs @ 105°C), providing enhanced thermal performance characteristics. These parts are also classified as obsolete.

Selection among Nichicon alternatives should account for packaging format requirements: bulk packaging for UVR1J330MED, or cut tape packaging for UVR1J330MED1TD, UPS1J330MED1TD, and UPW1J330MED1TD.

Frequently Asked Questions (FAQ)

Q: Can ECA-1JM330 be used as a direct replacement for ECA-1JM330I?

A: Yes. ECA-1JM330 is electrically and mechanically equivalent to ECA-1JM330I. The difference is packaging format: ECA-1JM330I is supplied in individual packaging while ECA-1JM330 is supplied in bulk. Both are Panasonic M-A series components with identical electrical specifications.

Q: Are Nichicon UVR and UPS series parts compatible with ECA-1JM330I?

A: Yes, all listed Nichicon parts meet the core electrical and mechanical requirements: 33 µF capacitance, 63 V voltage rating, ±20% tolerance, radial can package, 0.098" lead spacing, and 0.248" case diameter. Compatibility is confirmed for through-hole PCB applications with matching lead spacing and case dimensions.

Q: What is the difference between UVR1J330MED and UVR1J330MED1TD?

A: Both parts are electrically identical Nichicon UVR series components with 33 µF, 63 V specifications. The difference is packaging: UVR1J330MED is supplied in bulk format, while UVR1J330MED1TD is supplied in cut tape format. Selection depends on assembly process and procurement requirements.

Q: Why are some substitute parts marked as obsolete?

A: Product status reflects manufacturer production status. Obsolete parts may remain available through inventory channels but are no longer in active production. The ECA-1JM330 (Panasonic) remains active and is the preferred choice for new designs. Obsolete Nichicon alternatives are suitable for replacement applications where existing inventory is available.

Q: Can UPS1J330MED1TD or UPW1J330MED1TD be used in applications requiring -40°C to 85°C operation?

A: Yes. Both UPS1J330MED1TD and UPW1J330MED1TD are rated for -55°C to 105°C operating range, which encompasses the -40°C to 85°C requirement. These parts provide extended thermal performance margins beyond the ECA-1JM330I specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory compliance profile of the ECA-1JM330I.
