ECA-1VM100B Equivalent & Substitute Parts

Part Overview

The ECA-1VM100B is a 10 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 designed for general-purpose applications. The part is currently active in production with ROHS3 compliance.

Equivalent and substitute parts become necessary when the original part reaches end-of-life status, when inventory constraints occur, or when design requirements allow for higher voltage ratings or improved performance characteristics within the same physical and electrical envelope.

Substitute Part Grouping Explanation

Substitution logic for the ECA-1VM100B is based on the following criteria:

Electrical Parameters (Must Match or Exceed):

Capacitance: 10 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 35 V minimum (equal or higher ratings are acceptable)
Operating Temperature Range: -40°C ~ 85°C (must support full range)
Lifetime @ Temperature: 2000 Hrs @ 85°C (must meet or exceed)

Mechanical Parameters (Must Match):

Lead Spacing: 0.197" (5.00mm)
Case Diameter: 0.197" Dia (5.00mm)
Mounting Type: Through Hole
Package / Case: Radial, Can

Compliance Parameters:

RoHS Status: ROHS3 Compliant (required for new designs)
Polarization: Polar (fixed for this application)

Substitute parts are categorized as follows:

Upgrade Substitutes: Higher voltage ratings (50 V, 63 V) within the same physical footprint, maintaining all mechanical and thermal specifications.

Similar Substitutes: Higher voltage ratings (100 V) with identical mechanical dimensions and electrical characteristics except voltage.

Direct Substitutes: Alternative manufacturer parts with identical electrical and mechanical specifications.

Engineering Selection Recommendations

For Active Production Designs: Select from the Panasonic M-A series (ECA-1VM100B, ECA-1HM100B, ECA-1JM100B, or ECA-2AM100B). All parts are in active production status with ROHS3 compliance. Higher voltage ratings (50 V, 63 V, 100 V) provide design margin and are mechanically compatible with the original 35 V specification.

For Legacy System Maintenance: The Nichicon UVR series parts (UVR1V100MDD1TA, UVR1H100MDD1TA) are direct electrical equivalents but carry obsolete product status. These parts have a maximum seated height of 0.492" (12.50mm) compared to 0.472" (12.00mm) for Panasonic parts. This 0.020" (0.50mm) height difference must be evaluated for PCB clearance constraints before selection.

Compliance Consideration: All listed substitute parts maintain ROHS3 compliance and are suitable for applications requiring regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can I use ECA-1HM100B (50 V) in place of ECA-1VM100B (35 V)? A: Yes. The ECA-1HM100B is a direct mechanical and electrical substitute with a higher voltage rating. All mechanical dimensions, capacitance, tolerance, and thermal specifications are identical. The 50 V rating provides additional design margin.

Q: What is the difference between ECA-1JM100B and ECA-2AM100B? A: Both parts have identical capacitance (10 µF), tolerance (±20%), and mechanical dimensions. ECA-1JM100B is rated at 63 V, while ECA-2AM100B is rated at 100 V. Selection depends on the required voltage margin for your application.

Q: Why is the Nichicon UVR1V100MDD1TA listed as obsolete? A: Product status reflects manufacturer availability. Obsolete parts may have limited inventory and no guaranteed future supply. For new designs, Panasonic active parts are recommended.

Q: Does the 0.020" height difference between Panasonic and Nichicon parts affect PCB compatibility? A: The Nichicon UVR series has a maximum seated height of 0.492" (12.50mm) versus 0.472" (12.00mm) for Panasonic parts. This 0.50mm difference must be verified against PCB clearance requirements, component placement density, and enclosure constraints before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed in this reference maintain ROHS3 compliance status.

Q: Can I substitute a higher voltage part in a circuit designed for 35 V? A: Yes. A capacitor rated for higher voltage (50 V, 63 V, or 100 V) is electrically compatible in a 35 V circuit. The higher rating provides additional safety margin and does not degrade circuit performance.
