Equivalent & Substitute Parts for 156TLS050M

Part Overview

The 156TLS050M is a 150 µF, 50 V aluminum electrolytic capacitor in axial configuration, manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as Active and is designed for general-purpose applications requiring polarized capacitive energy storage. The part is ROHS3 compliant and REACH unaffected, making it suitable for modern electronic assemblies.

Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for aluminum electrolytic capacitors. Substitution becomes necessary when the primary part is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must match or exceed the application requirement within the specified tolerance band
• Voltage rating must equal or exceed the circuit operating voltage
• ESR and ripple current ratings must support the intended frequency and thermal environment
• Operating temperature range must encompass the application's thermal limits

Mechanical Compatibility:

• Mounting type must be identical (Through Hole for axial components)
• Package configuration must be compatible with PCB layout and assembly processes
• Physical dimensions must fit within board space constraints

Regulatory Compliance:

• RoHS and REACH status must meet end-product requirements
• MSL rating must be compatible with assembly and storage conditions

The substitute part MAL202138159E3 has been identified based on shared electrical characteristics and regulatory compliance, though specific parameter values differ from the main part.

Parameter Comparison

Engineering Selection Recommendations

156TLS050M (Primary Part): This part is Active and maintains full ROHS3 compliance and REACH unaffected status. Selection is appropriate when the specified capacitance of 150 µF at 50 V is required and inventory availability supports procurement timelines.

MAL202138159E3 (Substitute Part): This part is Active and maintains full ROHS3 compliance and REACH unaffected status. The substitute differs significantly in capacitance value (15 µF versus 150 µF), which represents a tenfold reduction. This part is suitable only for applications where the lower capacitance value is functionally equivalent to the circuit design. The higher voltage rating (63 V) and improved lifetime rating (2500 Hrs @ 85°C) provide enhanced performance margins in thermal environments. The smaller physical dimensions may offer space advantages in constrained layouts.

Selection between these parts must be based on circuit-level capacitance requirements. Direct substitution is not appropriate if the application specifically requires 150 µF capacitance.

Frequently Asked Questions (FAQ)

Q: Can MAL202138159E3 be used as a direct replacement for 156TLS050M?

A: Direct replacement is not appropriate. The substitute part has a capacitance value of 15 µF compared to the main part's 150 µF. Substitution is only valid if the circuit design permits operation with the lower capacitance value. Verify circuit requirements before selection.

Q: What are the key differences between these parts?

A: The primary differences are capacitance (150 µF vs. 15 µF), physical size (6.30mm x 13.00mm vs. 4.50mm x 10.00mm), and voltage rating (50 V vs. 63 V). Both parts share identical tolerance, operating temperature range, polarization, mounting type, and regulatory compliance status.

Q: Are both parts suitable for the same applications?

A: Both parts are classified for general-purpose applications and share identical regulatory compliance. However, application suitability depends on the specific capacitance requirement. The 150 µF part is appropriate for applications requiring higher capacitive energy storage, while the 15 µF part is suitable for lower-capacitance circuit functions.

Q: What is the impact of the different physical dimensions?

A: The substitute part is smaller (0.177" Dia x 0.394" L versus 0.248" Dia x 0.512" L). This may provide advantages in space-constrained PCB layouts. Verify that the smaller footprint is compatible with your board design and assembly equipment.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: How do the ESR values compare?

A: The main part has an ESR of 11.052 Ohm @ 120Hz, while the substitute has an ESR of 8.5 Ohm. The lower ESR of the substitute part indicates reduced impedance and improved performance in high-frequency ripple current applications.
