ECA-1VM220B Equivalent & Substitute Parts

Part Overview

The ECA-1VM220B is a 22 µF, 35 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This through-hole component is rated for 2000 hours at 85°C and is classified as Active product status. Substitute parts are identified when equivalent capacitance and tolerance specifications are maintained while accommodating different voltage ratings, thermal performance characteristics, or packaging requirements in system designs.

Substitute Part Grouping Explanation

Substitute parts for the ECA-1VM220B are qualified based on the following criteria:

Capacitance value: 22 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead spacing: 0.197" (5.00mm) (exact match required)
Mounting type: Through Hole (exact match required)
Package configuration: Radial, Can (exact match required)

Voltage rating, thermal lifetime, and operating temperature range may vary within the substitute group. Higher voltage ratings provide design margin in applications where the original 35 V specification is adequate. Extended thermal lifetime and higher maximum operating temperature support applications with elevated ambient conditions or extended service life requirements.

Engineering Selection Recommendations

All three parts maintain Active product status and comply with ROHS3 and REACH requirements. Selection between ECA-1VM220B, ECA-1JM220B, and EEU-FR1H220B depends on application voltage and thermal requirements:

ECA-1JM220B provides a 63 V rated voltage with identical thermal lifetime (2000 Hrs @ 85°C) and operating temperature range (-40°C ~ 85°C). This part is suitable for applications requiring higher voltage margin while maintaining the same thermal performance envelope as the original specification.

EEU-FR1H220B offers extended thermal lifetime (5000 Hrs @ 105°C) and expanded operating temperature range (-40°C ~ 105°C) with a 50 V rated voltage. This part accommodates applications with elevated ambient temperatures or extended service life requirements. Physical height increases from 12.00mm to 12.50mm; PCB layout verification is required.

Frequently Asked Questions (FAQ)

Q: Can ECA-1JM220B replace ECA-1VM220B in all applications?

A: ECA-1JM220B is electrically compatible where the 35 V specification is adequate. The higher 63 V rating provides additional design margin. Both parts share identical capacitance (22 µF), tolerance (±20%), thermal lifetime (2000 Hrs @ 85°C), and operating temperature range (-40°C ~ 85°C). Lead spacing and mounting configuration are identical.

Q: What is the primary difference between EEU-FR1H220B and the original ECA-1VM220B?

A: EEU-FR1H220B extends thermal lifetime to 5000 Hrs @ 105°C and supports operating temperatures up to 105°C, compared to 2000 Hrs @ 85°C and 85°C maximum for ECA-1VM220B. Capacitance, tolerance, and lead spacing remain identical. Physical height increases by 0.50mm (12.50mm vs. 12.00mm).

Q: Are there packaging differences between these parts?

A: ECA-1VM220B is supplied in Tape & Box (TB) packaging. Both ECA-1JM220B and EEU-FR1H220B are supplied in Cut Tape (CT) packaging. All three parts are through-hole radial configuration with 0.197" (5.00mm) lead spacing.

Q: Which substitute part should be selected for high-temperature applications?

A: EEU-FR1H220B is specified for operation up to 105°C with 5000 Hrs lifetime at that temperature. This part is appropriate for applications with sustained elevated ambient conditions. PCB layout must accommodate the increased height of 12.50mm.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. ECA-1VM220B, ECA-1JM220B, and EEU-FR1H220B are all ROHS3 Compliant and REACH Unaffected.
