SLP101M350A1P3 Equivalent & Substitute Parts

Part Overview

The SLP101M350A1P3 is a 100 µF, 350 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active product status and is designed for general-purpose applications requiring through-hole mounting with a 10.00 mm lead spacing and 22.00 mm diameter form factor.

Substitute parts are necessary when the original SLP101M350A1P3 becomes unavailable, when higher voltage ratings or extended lifetime specifications are required for circuit reliability, or when alternative manufacturers' components must be integrated into production due to supply chain considerations.

Substitute Part Grouping Explanation

Substitution eligibility for the SLP101M350A1P3 is determined by the following criteria:

Mandatory Matching Parameters:

Capacitance: 100 µF (exact match required)
Tolerance: ±20% (exact match required)
Package / Case: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 10.00 mm (exact match required)
Diameter: 22.00 mm (exact match required)
Polarization: Polar (exact match required)

Allowable Variation Parameters:

Voltage - Rated: Equal to or greater than 350 V (higher voltage ratings provide enhanced safety margin)
Lifetime @ 105°C: Equal to or greater than 3000 Hrs (extended lifetime improves reliability)
Operating Temperature Range: Must encompass -25°C to 105°C minimum
Height - Seated (Max): Up to 27.50 mm (minor dimensional tolerance acceptable within PCB layout constraints)

Substitute parts are grouped into two categories: direct equivalents at 400 V and higher-voltage upgrades at 450 V. All substitute parts maintain identical mechanical form factors and electrical characteristics within the specified tolerance bands.

Engineering Selection Recommendations

For Direct Replacement (350 V Equivalent): No direct 350 V equivalent parts are available in the substitute list. The SLP101M350A1P3 must be sourced directly or replaced with a higher voltage-rated alternative.

For 400 V Rated Substitutes: The following parts are suitable for applications where 400 V rating is acceptable:

B43508A9107M002 (EPCOS - TDK Electronics): Active product status, ROHS3 compliant, 3000 Hrs lifetime. Preferred for new designs requiring EPCOS sourcing.
B43644A9107M000 (EPCOS - TDK Electronics): Active product status, ROHS3 compliant, extended 5000 Hrs lifetime at 105°C. Recommended for applications requiring enhanced reliability.
ELXQ401VSN101MP25S (Chemi-Con): Active product status, RoHS compliant, extended 5000 Hrs lifetime. Suitable for Chemi-Con supply chain integration.
LGN2G101MELZ25 (Nichicon): Active product status, ROHS3 compliant, 3000 Hrs lifetime. Suitable for Nichicon supply chain integration.

For 420 V Rated Substitute:

LGNW6101MELZ25 (Nichicon): Active product status, ROHS3 compliant, 3000 Hrs lifetime. Provides intermediate voltage rating between 350 V and 450 V.

For 450 V Rated Upgrades:

450VXH100MEFCSN22X25 (Rubycon): Active product status, ROHS3 compliant, extended 5000 Hrs lifetime. Highest voltage rating with maximum reliability.
ELHS451VSN101MP25S (Chemi-Con): Active product status, RoHS compliant, extended 5000 Hrs lifetime, height 27.50 mm. Verify PCB clearance before selection.

Product Status Consideration: B43508A9107M000 carries "Not For New Designs" status and should be avoided in new circuit development. All other substitute parts carry Active status and are suitable for new designs.

Frequently Asked Questions (FAQ)

Q: Can the SLP101M350A1P3 be replaced with a 400 V rated capacitor?

A: Yes. A 400 V rated capacitor meets the substitution criteria because the voltage rating is equal to or greater than the original 350 V specification. The higher voltage rating provides additional safety margin in the circuit. All mechanical and electrical parameters must match exactly: 100 µF capacitance, ±20% tolerance, 10.00 mm lead spacing, 22.00 mm diameter, and radial snap-in package.

Q: What is the difference between 3000 Hrs and 5000 Hrs lifetime specifications?

A: Lifetime at 105°C indicates the expected operational duration before capacitance degradation reaches 80% of the initial value under specified conditions. A 5000 Hrs lifetime provides extended service life compared to 3000 Hrs. Both specifications meet the minimum requirement for substitution, but 5000 Hrs lifetime parts offer enhanced reliability for long-term applications.

Q: Are all substitute parts mechanically compatible with the original PCB layout?

A: All substitute parts maintain the same lead spacing (10.00 mm) and diameter (22.00 mm). Height dimensions range from 27.00 mm to 27.50 mm. The ELHS451VSN101MP25S has a maximum height of 27.50 mm, which is 0.50 mm taller than the original. Verify PCB clearance and component placement constraints before selecting this part.

Q: Which substitute part should be selected for new product designs?

A: For new designs, select only parts with Active product status. B43508A9107M000 carries "Not For New Designs" status and must be avoided. Recommended choices are B43508A9107M002, B43644A9107M000, ELXQ401VSN101MP25S, LGN2G101MELZ25, LGNW6101MELZ25, 450VXH100MEFCSN22X25, or ELHS451VSN101MP25S, depending on voltage rating and lifetime requirements.

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: Both ROHS3 Compliant and RoHS Compliant designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current standard. All substitute parts meet applicable RoHS requirements and are suitable for regulated markets.

Q: Can a 450 V capacitor be used in a circuit designed for 350 V?

A: Yes. A 450 V capacitor is electrically compatible with a 350 V circuit because the component is rated for higher voltage stress. The circuit will operate safely with the higher-rated component. However, verify that the physical dimensions (particularly the 27.50 mm height of ELHS451VSN101MP25S) do not conflict with PCB layout constraints.

Q: What is ESR and why does it vary among substitute parts?

A: Equivalent Series Resistance (ESR) represents the internal resistance of the capacitor at a specified frequency. ESR values provided in the original part specification (3.317 Ohm @ 120 Hz) and substitute parts vary based on internal construction and manufacturing. Lower ESR values indicate better high-frequency performance. ESR is not a substitution criterion; all parts with matching capacitance, voltage, and package are electrically compatible.
