Equivalent & Substitute Parts for 158KXM035M

Part Overview

The 158KXM035M is a 1500 µF, 35 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. Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate application-specific performance requirements such as extended operational lifetime or automotive-grade reliability certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 158KXM035M is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 1500 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)

Compatible Variation Parameters:

• Physical dimensions may vary within board space constraints
• Lifetime at temperature may exceed the original specification
• ESR and impedance values may differ while maintaining circuit performance
• Ripple current ratings may vary based on application requirements
• Compliance certifications (RoHS3, REACH) must be maintained

The substitute part ELXZ350ELL152MK35S from Chemi-Con meets all mandatory matching parameters and is therefore classified as a direct equivalent for the 158KXM035M.

Engineering Selection Recommendations

Primary Selection: 158KXM035M (Cornell Dubilier / Illinois Capacitor)

Use the 158KXM035M when:

• General purpose applications require standard performance specifications
• Supply availability from Cornell Dubilier is prioritized
• The 5000-hour lifetime at 105°C meets application requirements
• Cost optimization is the primary selection criterion

Substitute Selection: ELXZ350ELL152MK35S (Chemi-Con)

Use ELXZ350ELL152MK35S when:

• Extended operational lifetime is required (7000 hours at 105°C versus 5000 hours)
• Automotive-grade reliability is specified (AEC-Q200 certification)
• Lower impedance characteristics (22 mOhms versus 39 mOhms) benefit circuit performance
• Supply chain continuity requires an alternative source
• Both parts maintain identical electrical ratings (1500 µF, 35 V, ±20% tolerance)

Both parts are Active product status and maintain full RoHS3 and REACH compliance. The selection between these two parts depends on application-specific lifetime requirements and supply availability rather than electrical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can ELXZ350ELL152MK35S be used as a direct replacement for 158KXM035M without circuit modification?

A: Yes. Both parts share identical capacitance (1500 µF), voltage rating (35 V), tolerance (±20%), polarization (polar), package type (radial can), lead spacing (5.00mm), and operating temperature range (-55°C to 105°C). No circuit modification is required for substitution.

Q: What is the difference in physical dimensions between these two parts?

A: The 158KXM035M has a maximum seated height of 1.457" (37.00mm), while the ELXZ350ELL152MK35S has a maximum seated height of 1.437" (36.50mm). The diameter remains identical at 0.492" (12.50mm) for both parts. This 0.02" (0.50mm) height difference is negligible for most PCB layout applications.

Q: Why does the ELXZ350ELL152MK35S have lower ripple current ratings?

A: The ripple current ratings reflect the thermal and electrical design characteristics of each manufacturer's capacitor construction. The ELXZ350ELL152MK35S achieves a longer operational lifetime (7000 hours versus 5000 hours at 105°C) through different internal design parameters. Lower ripple current ratings do not indicate inferior performance; they reflect the specific thermal management approach of the Chemi-Con design.

Q: Is the ELXZ350ELL152MK35S suitable for automotive applications?

A: The ELXZ350ELL152MK35S carries AEC-Q200 certification, which qualifies it for automotive applications. The 158KXM035M does not specify automotive certification. If automotive-grade reliability is required, the ELXZ350ELL152MK35S is the appropriate selection.

Q: Can these capacitors be used interchangeably in existing inventory?

A: Yes, provided that the application does not have specific supply chain or certification requirements. Both parts are Active status, RoHS3 compliant, and REACH unaffected. Inventory management systems should track both part numbers separately to maintain supply chain traceability.

Q: What does the ±20% tolerance mean for these capacitors?

A: The ±20% tolerance indicates that the actual capacitance value may vary between 1200 µF and 1800 µF from the nominal 1500 µF specification. Both the 158KXM035M and ELXZ350ELL152MK35S share this identical tolerance specification, ensuring equivalent circuit performance characteristics.

Q: Are there any compliance or regulatory differences between these two parts?

A: Both parts are RoHS3 compliant and REACH unaffected. Both carry ECCN EAR99 and HTSUS 8532.22.0020 classifications. The primary regulatory difference is that ELXZ350ELL152MK35S includes AEC-Q200 automotive certification, while 158KXM035M does not specify this certification.
