Equivalent & Substitute Parts for 158KXM6R3M

Part Overview

The Cornell Dubilier 158KXM6R3M is a 1500 µF, 6.3 V aluminum electrolytic capacitor in radial, can package configuration. This component is rated for general-purpose applications with an operating temperature range of -55°C to 105°C and a lifetime specification of 4000 hours at 105°C. The part is currently active in production and ROHS3 compliant.

Substitute parts are identified when equivalent capacitance and tolerance values are maintained while voltage ratings may be increased, provided all mechanical and electrical parameters remain compatible with the original application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 158KXM6R3M is permissible with parts that maintain the following critical parameters:

• Capacitance Value: 1500 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Physical Dimensions: 0.394" Dia (10.00mm) and Height 0.866" (22.00mm) maximum (exact match or compatible)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Polarization: Polar (exact match required)

Voltage rating may be increased above the original 6.3 V specification, as higher voltage-rated capacitors are backward compatible in circuits designed for lower voltage operation. All substitute parts must be ROHS3 compliant and maintain through-hole radial can configuration.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with ROHS3 compliance and maintain full mechanical and electrical compatibility with the 158KXM6R3M.

16JXF1500MEFC10X20 (Rubycon JXF Series): This substitute provides a 16 V voltage rating with improved lifetime specification of 6000 hours at 105°C compared to the original 4000 hours. The lower impedance of 45 mOhms provides enhanced performance characteristics. This part is suitable for general-purpose applications where extended operational life is beneficial.

ELZA160ELL152MJ20S (Chemi-Con LZA Series): This substitute provides a 16 V voltage rating with AEC-Q200 automotive qualification. The lowest impedance of 35 mOhms among all options and height dimension of 0.846" (21.50mm) provide superior electrical performance. This part is designated for automotive applications and is appropriate for designs requiring automotive-grade reliability standards.

Both substitutes operate within the identical temperature range and maintain the same capacitance, tolerance, and physical footprint compatibility as the original part.

Frequently Asked Questions (FAQ)

Q: Can the 16JXF1500MEFC10X20 or ELZA160ELL152MJ20S be used as direct replacements for the 158KXM6R3M?

A: Yes. Both substitute parts maintain identical capacitance (1500 µF), tolerance (±20%), package configuration (radial, can), mounting type (through hole), lead spacing (5.00mm), and operating temperature range (-55°C to 105°C). The increased voltage ratings (16 V) are backward compatible with circuits designed for 6.3 V operation.

Q: What is the difference between the two substitute parts?

A: The 16JXF1500MEFC10X20 offers 6000-hour lifetime at 105°C with 45 mOhms impedance for general-purpose applications. The ELZA160ELL152MJ20S offers 4000-hour lifetime at 105°C with 35 mOhms impedance and AEC-Q200 automotive qualification, making it suitable for automotive applications requiring higher reliability standards.

Q: Are there any physical dimension differences that affect PCB layout?

A: The ELZA160ELL152MJ20S has a maximum seated height of 0.846" (21.50mm) compared to 0.866" (22.00mm) for both the original part and the Rubycon substitute. This 0.020" (0.50mm) difference is negligible for most applications and does not affect standard PCB layout compatibility.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. The 158KXM6R3M, 16JXF1500MEFC10X20, and ELZA160ELL152MJ20S are all ROHS3 compliant.

Q: What does the higher voltage rating on the substitute parts mean for circuit operation?

A: A capacitor with a higher voltage rating (16 V) can be used in circuits designed for lower voltage operation (6.3 V). The capacitor will operate safely with reduced electrical stress. Higher voltage-rated capacitors do not negatively affect circuit performance when used in lower voltage applications.

Q: Which substitute part should be selected for automotive applications?

A: The ELZA160ELL152MJ20S is designated for automotive applications with AEC-Q200 qualification and should be selected when automotive-grade reliability standards are required.
