Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAL212320108 is determined by the following critical parameters:

• Capacitance Value: Must be 1 µF (exact match required)
• Tolerance: ±20% (standard tolerance for aluminum electrolytic capacitors)
• Voltage Rating: Minimum 35 V (equal or higher voltage rating acceptable)
• Package Type: Axial, Can configuration with through-hole mounting
• Polarization: Polar (electrolytic capacitor type)
• Physical Dimensions: Compatible with 0.264" diameter and 0.602" length envelope

The substitute part 105TMA050M meets these core substitution criteria. It maintains identical capacitance and tolerance specifications while providing a higher voltage rating (50 V) and compatible axial package configuration. Physical dimensions are within acceptable tolerance for board-level integration.

Engineering Selection Recommendations

The 105TMA050M serves as a functional substitute for the obsolete MAL212320108 based on the following engineering criteria:

Electrical Compatibility: Both components share identical capacitance (1 µF) and tolerance (±20%) specifications. The substitute's higher voltage rating (50 V vs. 35 V) provides additional design margin and is electrically compatible with circuits designed for 35 V operation.

Physical Integration: The substitute features a smaller physical envelope (5.00mm x 13.00mm vs. 6.70mm x 15.30mm), which may require PCB layout verification but presents no functional impediment for through-hole mounting applications.

Compliance Status: The 105TMA050M is ROHS3 compliant and carries active product status, ensuring long-term availability and regulatory alignment. The original MAL212320108 is RoHS non-compliant and obsolete.

Operational Considerations: The substitute operates across a narrower temperature range (-40°C to 105°C vs. -55°C to 125°C). Applications requiring the full -55°C to 125°C range must evaluate this limitation against specific system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 105TMA050M directly replace the MAL212320108 without circuit modification?

A: Yes, from an electrical standpoint. Both components have identical capacitance and tolerance. The higher voltage rating of the substitute is compatible with 35 V circuit designs. Physical dimensions differ slightly; verify PCB layout accommodates the smaller 5.00mm x 13.00mm package.

Q: What is the significance of the voltage rating difference (35 V vs. 50 V)?

A: The substitute's 50 V rating exceeds the original 35 V specification, providing additional safety margin. This is acceptable for direct substitution in circuits designed for 35 V operation. No derating is required.

Q: Does the smaller physical size of the 105TMA050M affect performance?

A: Physical size does not affect electrical performance. The smaller dimensions (5.00mm x 13.00mm vs. 6.70mm x 15.30mm) may require PCB layout adjustment but present no functional degradation.

Q: Why does the substitute have a lower lifetime rating (2,000 Hrs @ 105°C vs. 20,000 Hrs @ 125°C)?

A: Lifetime specifications are measured at different temperature points. Direct comparison requires thermal modeling. Applications operating continuously at 125°C should evaluate whether the substitute's 105°C thermal rating meets system requirements.

Q: Is the 105TMA050M suitable for high-temperature applications?

A: The substitute operates to 105°C maximum, compared to the original's 125°C rating. Applications requiring sustained operation above 105°C must seek alternative components with higher temperature specifications.

Q: What compliance advantages does the 105TMA050M offer?

A: The substitute is ROHS3 compliant and carries active product status, ensuring regulatory alignment and ongoing availability. The original MAL212320108 is obsolete and RoHS non-compliant.
