Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 158LMB160M2EE is based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 1500 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Physical Dimensions: 1.378" Dia × 1.457" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Style: Radial, Can - Snap-In (exact match required)
• Polarization: Polar (exact match required)

Permissible Variation Parameters:

• Voltage Rating: 160 V minimum; higher ratings (200 V) are acceptable substitutes
• Operating Temperature Range: -25°C ~ 105°C minimum; extended ranges (e.g., -40°C ~ 105°C) are acceptable
• Lifetime @ 105°C: 3000 Hrs minimum; equal or longer lifetimes are acceptable
• ESR and Ripple Current: Variations permitted provided electrical performance meets or exceeds application requirements

Compliance Requirements:

• RoHS3 Compliance: Must be maintained
• REACH Status: Must remain unaffected

All three substitute parts listed meet these criteria and are qualified alternatives to the 158LMB160M2EE.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified alternatives to the 158LMB160M2EE based on the following engineering criteria:

Voltage Rating Upgrade: All substitute parts operate at 200 V rated voltage, which exceeds the 160 V specification of the main part. This provides additional voltage margin and is electrically compatible with circuits designed for 160 V operation.

Temperature Range Compatibility: The B43509B2158M000 (EPCOS - TDK) and LGN2D152MELC35 (Nichicon) extend the lower operating temperature limit to -40°C, compared to -25°C for the main part. This represents an enhancement for applications requiring extended cold-temperature operation. The 200MXG1500MEFCSN35X35 (Rubycon) maintains the -25°C lower limit.

Lifetime and Reliability: All substitute parts maintain the 3000 Hrs @ 105°C lifetime specification, ensuring equivalent long-term reliability in thermal stress conditions.

Mechanical and Electrical Compatibility: All substitute parts share identical physical dimensions (1.378" Dia × 1.457" Height), lead spacing (0.394" / 10.00 mm), and mounting configuration (Through Hole, Radial, Can - Snap-In). Direct PCB substitution is mechanically feasible without layout modifications.

Compliance Status: All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the main part.

Ripple Current Performance: The 200MXG1500MEFCSN35X35 and LGN2D152MELC35 provide ripple current ratings (2.8 A @ 120 Hz, 4.2 A @ 10 kHz) comparable to the main part. The B43509B2158M000 specifies lower ripple current (2.37 A @ 100 Hz), which may be a limiting factor in high-ripple-current applications.

ESR Characteristics: The B43509B2158M000 specifies lower ESR (95 mOhm @ 100 Hz) compared to the main part (165.786 mOhm @ 120 Hz), indicating superior high-frequency performance. The other two substitutes do not specify ESR values.

Inventory Availability: The Rubycon (200MXG1500MEFCSN35X35) and Nichicon (LGN2D152MELC35) parts offer significantly higher stock levels (274,082 and 273,882 units respectively), providing supply security for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the 200MXG1500MEFCSN35X35 (Rubycon) be used as a direct replacement for the 158LMB160M2EE?

A: Yes. The Rubycon part matches all mandatory electrical and mechanical parameters: 1500 µF capacitance, ±20% tolerance, identical physical dimensions (1.378" Dia × 1.457" Height), 10.00 mm lead spacing, and radial snap-in package configuration. The 200 V voltage rating exceeds the 160 V requirement and is compatible with existing circuit designs. Both parts maintain ROHS3 compliance and 3000 Hrs @ 105°C lifetime specifications.

Q: What is the difference between the B43509B2158M000 (EPCOS - TDK) and the other substitutes?

A: The B43509B2158M000 offers the lowest ESR specification (95 mOhm @ 100 Hz) among the three substitutes, providing superior performance in high-frequency ripple current applications. It also extends the operating temperature range to -40°C, compared to -25°C for the main part and Rubycon substitute. However, its ripple current rating (2.37 A @ 100 Hz) is lower than the main part and other substitutes, which may limit its use in applications with high ripple current demands.

Q: Are there any mechanical compatibility issues when substituting these parts?

A: No. All substitute parts maintain identical physical dimensions and lead spacing to the 158LMB160M2EE. The 1.378" diameter, 1.457" maximum seated height, and 0.394" (10.00 mm) lead spacing are consistent across all parts. Direct PCB substitution is mechanically feasible without layout or mounting modifications.

Q: Can I use a 200 V rated capacitor in a circuit designed for 160 V operation?

A: Yes. A higher voltage-rated capacitor is electrically compatible with lower-voltage circuit designs. The 200 V rating provides additional voltage margin and does not negatively affect circuit performance. All three substitute parts operate at 200 V and are suitable for 160 V applications.

Q: Which substitute part offers the best supply availability?

A: The Nichicon LGN2D152MELC35 and Rubycon 200MXG1500MEFCSN35X35 both offer substantially higher inventory levels (273,882 and 274,082 units respectively) compared to the EPCOS - TDK B43509B2158M000 (1,148 units). For high-volume production or long-term supply security, the Nichicon or Rubycon parts are preferred.

Q: Do all substitute parts comply with RoHS and REACH regulations?

A: Yes. All three substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the 158LMB160M2EE.

Q: What is the significance of the extended temperature range (-40°C) offered by the EPCOS - TDK and Nichicon parts?

A: The extended lower operating temperature limit to -40°C (compared to -25°C for the main part) allows these parts to function reliably in colder environments or applications with extreme thermal cycling. This is an enhancement for applications requiring cold-temperature operation, though it is not necessary for circuits designed within the -25°C to 105°C range.

Q: Are there any performance differences in ripple current handling between the substitutes?

A: Yes. The Rubycon 200MXG1500MEFCSN35X35 and Nichicon LGN2D152MELC35 specify ripple current ratings (2.8 A @ 120 Hz, 4.2 A @ 10 kHz) comparable to the main part (2.84 A @ 120 Hz, 4.175 A @ 10 kHz). The EPCOS - TDK B43509B2158M000 specifies lower ripple current (2.37 A @ 100 Hz), which may be insufficient for applications with high ripple current demands. Verify ripple current requirements before selecting this part.
