Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN101M035ST is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 100 µF (exact match required)
• Voltage rating: 35 V (minimum acceptable)
• Tolerance: ±20% (matching specification)
• Operating temperature range: -40°C ~ 85°C (minimum acceptable)
• Polarization: Bi-Polar (functional requirement)

Mechanical Parameters:

• Mounting type: Through Hole (PCB compatibility)
• Package type: Radial, Can (form factor requirement)
• Lead spacing: 0.197" (5.00mm) (footprint compatibility)

Compliance Parameters:

• RoHS3 Compliance (regulatory requirement)

The ECE-A1VN101U from Panasonic Electronic Components meets all critical substitution criteria and is classified as an active product with enhanced reliability specifications.

Parameter Comparison

Engineering Selection Recommendations

The ECE-A1VN101U is a direct functional equivalent to the SN101M035ST for applications requiring 100 µF, 35 V aluminum electrolytic capacitors with through-hole radial mounting. Both components satisfy identical electrical specifications and RoHS3 compliance requirements.

The Panasonic ECE-A1VN101U offers the following advantages based on provided specifications:

• Active product status ensures ongoing availability and supply chain continuity
• Extended lifetime rating of 2000 Hrs @ 85°C compared to 1000 Hrs @ 85°C
• Smaller physical dimensions (0.394" diameter, 0.630" height) provide improved PCB layout flexibility
• REACH Unaffected status provides additional regulatory documentation

The substitute part maintains identical lead spacing (0.197" / 5.00mm) and operates within the same temperature range (-40°C ~ 85°C), ensuring direct PCB footprint compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the ECE-A1VN101U replace the SN101M035ST in existing designs?

A: Yes. Both components share identical electrical specifications (100 µF, ±20%, 35 V), operating temperature range (-40°C ~ 85°C), and lead spacing (0.197" / 5.00mm). The substitute part is mechanically compatible with existing through-hole PCB layouts.

Q: What is the difference in physical size between these components?

A: The SN101M035ST has a diameter of 0.512" (13.00mm) and height of 0.787" (20.00mm). The ECE-A1VN101U has a diameter of 0.394" (10.00mm) and height of 0.630" (16.00mm). The smaller Panasonic component may provide additional PCB routing space in space-constrained designs.

Q: Are both components RoHS3 compliant?

A: Yes. Both the SN101M035ST and ECE-A1VN101U are ROHS3 Compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the SN101M035ST classified as obsolete?

A: The SN101M035ST is an obsolete product from Cornell Dubilier Electronics. The ECE-A1VN101U from Panasonic is an active product with current manufacturing support and supply availability.

Q: What is the difference in ripple current ratings?

A: The SN101M035ST is rated for 285 mA ripple current at 120 Hz. The ECE-A1VN101U is rated for 230 mA at 120 Hz and 391 mA at 10 kHz. Application-specific ripple current requirements determine suitability for each component.

Q: Is the lead spacing identical between both parts?

A: Yes. Both components have identical lead spacing of 0.197" (5.00mm), ensuring direct footprint compatibility without PCB modification.
