ECA-1JM330B Equivalent & Substitute Parts

Part Overview

The ECA-1JM330B is a 33 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This component is classified as Active product status and is designed for general purpose applications requiring reliable energy storage and filtering in electronic circuits. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when design flexibility allows for equivalent electrical and mechanical specifications. The substitutes listed maintain identical core electrical parameters while potentially offering different packaging configurations or manufacturer alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECA-1JM330B is determined by strict equivalence across the following critical parameters:

• Capacitance value: 33 µF (exact match required)
• Rated voltage: 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)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Lifetime rating: 2000 Hrs @ 85°C (exact match required)

Variations in lead spacing, ripple current ratings, and physical height are permitted within the substitute group, as these do not affect functional equivalence when the core electrical specifications remain identical. All substitutes maintain ROHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

ECA-1JM330 (Panasonic) is the primary substitute for ECA-1JM330B. Both parts are manufactured by Panasonic, maintain Active product status, and are electrically and mechanically equivalent. The primary difference is packaging configuration (tape and reel versus bulk). This substitute is suitable for direct replacement in all applications where the ECA-1JM330B is specified.

UVR1J330MED (Nichicon) is functionally equivalent but carries Obsolete product status. This part maintains all critical electrical parameters and compliance certifications (ROHS3, REACH unaffected). Physical differences include reduced maximum seated height (0.433" versus 0.480") and increased ripple current ratings. Selection of this substitute should account for its obsolete status and potential future availability constraints.

All substitutes maintain compliance with ROHS3 and REACH requirements, ensuring regulatory compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can ECA-1JM330 be used as a direct replacement for ECA-1JM330B?

A: Yes. Both parts share identical electrical specifications (33 µF, 63 V, ±20% tolerance, 2000 Hrs @ 85°C) and mechanical form factors. The difference is packaging type. ECA-1JM330 is supplied in bulk packaging, while ECA-1JM330B uses standard packaging. Electrical performance and PCB mounting are equivalent.

Q: What is the difference in lead spacing between ECA-1JM330B and ECA-1JM330?

A: ECA-1JM330B has 0.197" (5.00mm) lead spacing, while ECA-1JM330 has 0.098" (2.50mm) lead spacing. This affects PCB hole pattern design. Verify your PCB layout accommodates the selected part's lead spacing before implementation.

Q: Is UVR1J330MED suitable for new designs?

A: UVR1J330MED is classified as Obsolete. While electrically equivalent and compliant with ROHS3 and REACH standards, its obsolete status indicates limited future availability. For new designs, ECA-1JM330 or ECA-1JM330B are recommended to ensure long-term supply chain stability.

Q: Do all substitutes operate across the same temperature range?

A: Yes. All listed substitutes operate across -40°C to 85°C with 2000 hours lifetime at 85°C. Temperature performance is equivalent across the substitute group.

Q: What are the ripple current differences between substitutes?

A: ECA-1JM330B and ECA-1JM330 both support 130 mA @ 120 Hz and 221 mA @ 10 kHz. UVR1J330MED supports higher ripple currents: 140 mA @ 120 Hz and 280 mA @ 10 kHz. Higher ripple current capability does not affect compatibility; it indicates enhanced thermal performance in the Nichicon part.
