158KXM025M Equivalent & Substitute Parts

Part Overview

The 158KXM025M is a 1500 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as Active product status and is designed for general purpose applications. The capacitor operates across a temperature range of -55°C to 105°C with a rated lifetime of 5000 hours at 105°C.

Frequently Asked Questions (FAQ)

Q: Can the B41888C5158M000 be used as a direct replacement for the 158KXM025M?

A: Yes. Both parts share identical capacitance (1500 µF), voltage rating (25 V), tolerance (±20%), lead spacing (5.00mm), and radial can package format. The B41888C5158M000 provides enhanced performance with lower impedance and extended lifetime.

Q: What is the difference between the ELXZ250ELL152MK25S and ELZA350ELL152MK25S?

A: The primary difference is voltage rating: ELXZ250ELL152MK25S is rated at 25 V, while ELZA350ELL152MK25S is rated at 35 V. Both share identical capacitance (1500 µF), tolerance (±20%), and physical dimensions. The 35 V rated part provides additional voltage margin and lower impedance (22 mOhms versus 30 mOhms).

Q: Are all substitute parts automotive-qualified?

A: Yes. All four substitute parts carry AEC-Q200 certification, indicating compliance with automotive reliability standards. The main part (158KXM025M) does not list AEC-Q200 qualification.

Q: What is the significance of impedance differences among these parts?

A: Impedance directly affects ripple current handling and heat dissipation. Lower impedance values indicate better high-frequency performance and reduced electrical losses. The ELZA350ELL152MK25S has the lowest impedance at 22 mOhms, while the main part has 45 mOhms.

Q: Can the MAL214656152E3 be used in applications requiring operation above 105°C?

A: Yes. The MAL214656152E3 is rated for operation up to 125°C, extending the usable temperature range by 20°C compared to the main part and other substitutes. Lifetime rating is specified at 125°C rather than 105°C.

Q: Are there physical dimension constraints when substituting these parts?

A: Lead spacing (5.00mm) and diameter (12.50mm) are identical across all parts. Height varies slightly: the main part and B41888C5158M000 and MAL214656152E3 have maximum seated heights of 1.063 inches, while ELXZ250ELL152MK25S and ELZA350ELL152MK25S have maximum seated heights of 1.043 inches. This 0.020-inch difference is negligible for most through-hole PCB applications.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. All listed parts, including the main part, are ROHS3 compliant.

Q: Which substitute part offers the best overall performance?

A: Selection depends on application requirements. The B41888C5158M000 provides doubled lifetime (10000 hours). The ELZA350ELL152MK25S offers lowest impedance (22 mOhms) and higher voltage rating (35 V). The MAL214656152E3 extends maximum operating temperature to 125°C.
