Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPX151M350A5P3 is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 150 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Physical diameter: 0.866" (22.00mm) (exact match required)
• Polarization: Polar (exact match required)

Secondary Compatibility Parameters:

• Voltage rating: Equal to or greater than 350 V
• RoHS3 compliance: Required
• REACH compliance: Required

The substitute part B43508A9157M000 meets all primary substitution criteria and exceeds the voltage rating specification, making it electrically and mechanically compatible with the LPX151M350A5P3.

Parameter Comparison

Engineering Selection Recommendations

The B43508A9157M000 (EPCOS - TDK Electronics) is a direct substitute for the LPX151M350A5P3. Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for current applications.

Selection Basis:

The substitute part satisfies all mechanical and electrical compatibility requirements. The 400 V voltage rating of the B43508A9157M000 exceeds the 350 V requirement of the LPX151M350A5P3, providing additional voltage margin. The substitute part's maximum seated height of 1.260" (32.00mm) is 0.118" shorter than the main part's 1.378" (35.00mm), which must be verified against available PCB clearance in the target application. Both parts feature identical lead spacing (10.00mm) and diameter (22.00mm), ensuring direct mechanical compatibility with existing through-hole footprints.

The B43508A9157M000 is currently in stock with 1360 units available, supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the B43508A9157M000 be used as a direct replacement for the LPX151M350A5P3?

A: Yes. Both parts share identical capacitance (150 µF), tolerance (±20%), package type (Radial, Can - Snap-In), mounting type (Through Hole), lead spacing (10.00mm), and physical diameter (22.00mm). The substitute part's 400 V rating exceeds the 350 V requirement, and both parts are ROHS3 compliant and REACH unaffected.

Q: What is the height difference between these two parts?

A: The LPX151M350A5P3 has a maximum seated height of 1.378" (35.00mm), while the B43508A9157M000 has a maximum seated height of 1.260" (32.00mm). The substitute is 0.118" shorter. Verify available vertical clearance on the PCB before substitution.

Q: Are the lead spacings identical?

A: Yes. Both the LPX151M350A5P3 and B43508A9157M000 have a lead spacing of 0.394" (10.00mm), confirming mechanical compatibility with existing through-hole footprints.

Q: Does the higher voltage rating of the substitute part affect circuit performance?

A: No. A capacitor with a higher voltage rating than required operates within specification when used at the lower voltage. The 400 V rating of the B43508A9157M000 provides additional voltage margin when used in a 350 V application.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the LPX151M350A5P3 and B43508A9157M000 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the operating temperature range for each part?

A: The LPX151M350A5P3 operates from -40°C to 85°C. The B43508A9157M000 operates from -40°C to 105°C. The substitute part supports a wider operating temperature range.
