Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical electrical and mechanical parameters:

Core Electrical Compatibility Requirements:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 100 V (minimum, equal or greater)
• Polarization: Polar (aluminum electrolytic)
• Package / Case: Axial, Can (form factor compatibility)
• Mounting Type: Through Hole (circuit board integration)

Secondary Electrical Considerations:

• Tolerance: ±20% (substitute parts show wider tolerance than original -10%, +75%)
• ESR: Substitute parts demonstrate lower ESR values (266–645 mOhm range versus 550 mOhm), indicating improved performance characteristics
• Lifetime @ Temperature: Substitute parts provide extended operational life (8000 Hrs @ 85°C or 8000 Hrs @ 125°C versus 1000 Hrs @ 85°C)
• Operating Temperature: Extended operating range available (-40°C ~ 125°C for one substitute versus -40°C ~ 85°C)

Physical Compatibility Considerations:

• Substitute parts feature smaller physical dimensions (12.50–15.00 mm diameter versus 19.05 mm), allowing installation in space-constrained applications
• All substitute parts maintain axial, can configuration compatible with through-hole circuit board design
• Mechanical fit depends on specific PCB layout and lead spacing requirements

The two identified substitute parts, MAL202119151E3 and MAL212019151E3, both satisfy the core electrical and mechanical compatibility requirements for the TC10151.

Parameter Comparison

Engineering Selection Recommendations

MAL202119151E3 (Vishay 021 ASM Series)

This substitute is active product status with ROHS3 compliance, offering 8 times the rated lifetime at 85°C compared to the TC10151 (8000 hours versus 1000 hours). The 645 mOhm ESR remains within acceptable operational parameters for general-purpose aluminum electrolytic applications. Physical dimensions are significantly smaller (12.50 mm diameter), allowing integration into modern, space-constrained circuit board designs. Selection of this substitute is appropriate for applications where extended operational life and compliance certification are not critical constraints.

MAL212019151E3 (Vishay 120 ATC Series)

This substitute delivers superior performance characteristics with the lowest ESR value (266 mOhm) and extended operating temperature range (-40°C ~ 125°C). The 8000-hour lifetime at 125°C operational temperature provides the longest service reliability. This part carries ROHS3 compliance and AEC-Q200 automotive qualification, positioning it as the optimal substitute for applications requiring extended temperature operation, compliance certifications, and lowest impedance characteristics. The ripple current rating of 1.48 A @ 10 kHz matches the original TC10151 specification, ensuring equivalent frequency response performance.

Both Vishay substitutes satisfy the core electrical and mechanical compatibility requirements for the obsolete TC10151, with MAL212019151E3 recommended for applications prioritizing extended temperature operation and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can MAL202119151E3 and MAL212019151E3 be used interchangeably with the TC10151?

A: Both Vishay substitutes meet the core electrical specifications (150 µF, 100 V, polar, axial configuration, through-hole mounting). However, physical dimension differences affect mechanical fit. The TC10151 measures 19.05 mm diameter, while MAL202119151E3 is 12.50 mm and MAL212019151E3 is 15.00 mm in diameter. Verify PCB layout accommodates the selected substitute's physical dimensions.

Q: What is the impact of the tolerance difference between the original TC10151 and the Vishay substitutes?

A: The TC10151 specifies -10%, +75% tolerance, while both Vishay substitutes specify ±20% tolerance. The substitute tolerance is narrower on the lower bound (-20% versus -10%) but wider on the upper bound (+20% versus +75%). Applications sensitive to capacitance variation at the lower end (-20% point) require circuit-level performance evaluation.

Q: Are the Vishay substitutes suitable for automotive applications?

A: MAL212019151E3 carries AEC-Q200 automotive qualification rating and is specified for automotive applications. MAL202119151E3 is general-purpose rated without automotive qualification. Selection depends on application requirements and industry standards compliance.

Q: How do the ripple current specifications compare?

A: The TC10151 handles 1.48 A @ 2.4 kHz. MAL202119151E3 is rated 686 mA @ 10 kHz, representing a reduction in ripple current capacity at higher frequencies. MAL212019151E3 is rated 1.48 A @ 10 kHz, matching the original specification at higher operating frequency, providing equivalent ripple current handling capability.

Q: What compliance considerations apply to these parts?

A: The original TC10151 is RoHS non-compliant. Both Vishay substitutes are ROHS3 compliant. Modern applications requiring environmental compliance certification should utilize the Vishay alternatives. MAL212019151E3 additionally carries AEC-Q200 rating for automotive applications.

Q: Does the lower ESR of MAL212019151E3 provide a performance advantage?

A: Lower ESR (266 mOhm versus 550 mOhm) reduces impedance and heat generation during operation. This characteristic benefits high-ripple-current applications and systems requiring extended operational life with reduced thermal stress. Applications with minimal ripple current requirements see minimal practical advantage from the lower ESR value.
