Substitute Part Grouping Explanation

Substitution eligibility for the 158KXM016M is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 1500 µF (exact match)
• Voltage Rating: 16 V (exact match)
• Tolerance: ±20% (exact match)
• Polarization: Polar (exact match)
• Operating Temperature Range: -55°C to 105°C (exact match)

Mechanical Equivalence Requirements:

• Package Type: Radial, Can (exact match)
• Lead Spacing: 0.197" (5.00mm) (exact match)
• Diameter: 0.492" (12.50mm) (exact match)
• Mounting Type: Through Hole (exact match)

Compliance Requirements:

• RoHS3 Compliant (exact match)
• REACH Unaffected (exact match)

The substitute part ELXZ160ELL152MK20S from Chemi-Con meets all electrical and mechanical equivalence criteria. Variations in secondary parameters such as ESR, ripple current ratings, lifetime specifications, and impedance do not disqualify substitution when primary parameters remain equivalent.

Engineering Selection Recommendations

Primary Substitution: ELXZ160ELL152MK20S

The Chemi-Con ELXZ160ELL152MK20S qualifies as a direct substitute for the 158KXM016M based on complete electrical and mechanical parameter equivalence. Both components are Active status products with RoHS3 compliance and REACH unaffected designation.

The substitute part demonstrates extended lifetime specification (7000 Hrs @ 105°C versus 5000 Hrs @ 105°C) and lower impedance (38 mOhms versus 53 mOhms), representing performance characteristics that do not compromise circuit functionality. The height difference of 0.020" (0.50mm) remains within typical PCB layout tolerances for through-hole radial capacitor applications.

The Chemi-Con part carries AEC-Q200 automotive qualification, indicating suitability for applications requiring enhanced reliability standards, though this certification does not restrict use in general purpose applications.

Frequently Asked Questions (FAQ)

Q: Can ELXZ160ELL152MK20S be used as a direct replacement for 158KXM016M in existing circuit designs?

A: Yes. Both components share identical capacitance (1500 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-55°C to 105°C), and mechanical dimensions (0.492" diameter, 5.00mm lead spacing, through-hole radial package). PCB footprints and circuit performance remain equivalent.

Q: What is the significance of the height difference between the two parts?

A: The 158KXM016M has a maximum seated height of 0.866" (22.00mm), while the ELXZ160ELL152MK20S measures 0.846" (21.50mm). This 0.020" (0.50mm) difference is within standard PCB layout clearance tolerances and does not affect mechanical or electrical compatibility in typical applications.

Q: Why does the substitute part have different ripple current ratings?

A: Ripple current specifications reflect the thermal and electrical design characteristics of each manufacturer's capacitor construction. The 158KXM016M specifies 1.416 A @ 120 Hz and 2.36 A @ 100 kHz, while the ELXZ160ELL152MK20S specifies 996 mA @ 120 Hz and 1.66 A @ 100 kHz. Circuit designs must verify that actual ripple current requirements do not exceed the substitute part's ratings.

Q: Are both parts suitable for automotive applications?

A: The 158KXM016M is classified for general purpose applications. The ELXZ160ELL152MK20S carries AEC-Q200 automotive qualification. Both parts are RoHS3 compliant and REACH unaffected. Application suitability depends on specific circuit requirements and environmental conditions beyond component classification.

Q: What does the extended lifetime specification of the substitute part indicate?

A: The ELXZ160ELL152MK20S specifies 7000 Hrs @ 105°C compared to 5000 Hrs @ 105°C for the 158KXM016M. This represents the manufacturer's rated operational life under specified thermal conditions. Extended lifetime does not alter electrical equivalence but may indicate different internal construction or material selection.

Q: Can these parts be used interchangeably in high-frequency applications?

A: Both components are rated for ripple current at 100 kHz. Circuit designs must verify that actual operating frequencies and ripple current magnitudes remain within the specified ratings of the selected part. The lower impedance of the substitute part (38 mOhms versus 53 mOhms) may provide improved high-frequency performance characteristics.
