Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC75101 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Capacitance value: 100 µF (exact match required)
• Polarization: Polar (electrolytic type)
• Package / Case: Axial, Can (form factor and lead configuration)
• Mounting Type: Through Hole (PCB assembly method)

Electrical Performance Criteria:

• Voltage rating must equal or exceed 75 V
• ESR and ripple current ratings must support the application's electrical demands
• Operating temperature range must encompass -40°C to 85°C minimum

Compliance Considerations:

• RoHS status and REACH compliance affect suitability for regulated applications
• Product status (Active vs. Obsolete) impacts long-term availability

The three substitute parts listed (MAL202119101E3, MAL202190532E3, MAL212029101E3) all meet the mandatory compatibility criteria with 100 µF capacitance, polar electrolytic construction, axial can package, and through-hole mounting. All substitutes feature 100 V rated voltage, exceeding the TC75101's 75 V specification, providing voltage margin. All substitutes are manufactured by Vishay Beyschlag/Draloric/BC Components and carry Active product status with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

MAL202119101E3 Selection Criteria: This substitute is suitable for general-purpose applications requiring standard operating conditions within -40°C to 85°C. The part offers 8000-hour lifetime at 85°C, significantly extending service life compared to the TC75101's 1000-hour rating. ROHS3 compliance makes this option appropriate for regulated markets. The 100 V voltage rating provides adequate margin above the original 75 V specification. Physical dimensions (10.00 mm diameter × 30.00 mm length) are smaller than the original part, requiring PCB layout verification for mechanical fit.

MAL202190532E3 Selection Criteria: This variant is applicable where space constraints are critical, featuring the smallest axial can dimensions (10.00 mm diameter × 25.00 mm length). The 2500-hour lifetime at 85°C is intermediate between the original and MAL202119101E3. ROHS3 compliance is maintained. This option is suitable for compact designs where the reduced physical footprint justifies the lower lifetime rating.

MAL212029101E3 Selection Criteria: This substitute is designated for automotive applications, carrying AEC-Q200 qualification. The extended operating temperature range (-40°C to 125°C) and 8000-hour lifetime at 125°C provide superior thermal performance. The 389 mOhm ESR is the lowest among all substitutes, offering improved ripple current handling (1.14 A @ 10 kHz). Physical dimensions (12.50 mm diameter × 30.00 mm length) fall between the original and other substitutes. ROHS3 compliance is confirmed. This option is mandatory for automotive-grade applications.

Compliance Consideration: All three substitutes are ROHS3 compliant, whereas the TC75101 is RoHS non-compliant. Applications subject to RoHS regulations must transition to one of these substitutes.

Frequently Asked Questions (FAQ)

Q: Can MAL202119101E3, MAL202190532E3, or MAL212029101E3 directly replace TC75101 in existing PCB designs?

A: Direct replacement requires verification of physical fit. The TC75101 measures 0.625" diameter × 1.375" length, while all substitutes are smaller. MAL202119101E3 and MAL202190532E3 measure 0.394" diameter, and MAL212029101E3 measures 0.492" diameter. PCB hole spacing and component clearance must be confirmed before substitution. Electrical compatibility is confirmed for all three substitutes.

Q: What is the primary difference between MAL202119101E3 and MAL202190532E3?

A: Both parts share identical electrical specifications (100 µF, 100 V, ±20% tolerance, polar, axial can, through-hole). The primary differences are physical dimensions and lifetime rating. MAL202119101E3 is 30.00 mm long with 8000-hour lifetime at 85°C. MAL202190532E3 is 25.00 mm long with 2500-hour lifetime at 85°C. Selection depends on space constraints and required service life.

Q: Why does MAL212029101E3 have different specifications than the other two substitutes?

A: MAL212029101E3 is from the 120 ATC series designed for automotive applications with AEC-Q200 qualification. It features extended temperature range (-40°C to 125°C), lower ESR (389 mOhm), higher ripple current capability (1.14 A @ 10 kHz), and 8000-hour lifetime at 125°C. These enhancements support demanding automotive environments. This part is required for automotive-grade applications; the other substitutes are suitable for general-purpose use.

Q: Are all three substitutes RoHS compliant?

A: Yes. All three substitutes (MAL202119101E3, MAL202190532E3, MAL212029101E3) carry ROHS3 compliance status. The original TC75101 is RoHS non-compliant. Applications subject to RoHS regulations must transition to one of these compliant substitutes.

Q: What is the voltage margin provided by the substitutes?

A: The TC75101 is rated at 75 V. All three substitutes are rated at 100 V, providing a 25 V margin (33% overvoltage rating). This margin improves reliability and accommodates voltage transients in the application circuit.

Q: Which substitute offers the best ESR performance?

A: MAL212029101E3 provides the lowest ESR at 389 mOhm, compared to 770 mOhm for the original TC75101. MAL202119101E3 and MAL202190532E3 have higher ESR values (1.15 Ohm and 1.3 Ohm respectively). Lower ESR reduces heat generation and improves ripple current handling, making MAL212029101E3 optimal for high-ripple-current applications.

Q: Can these substitutes be used in applications requiring the original -10%, +75% tolerance?

A: No. All three substitutes feature ±20% tolerance, which is tighter than the original TC75101's -10%, +75% tolerance. Applications requiring the original asymmetric tolerance specification cannot use these substitutes without circuit redesign to accommodate the tighter tolerance band.
