Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 105SMH050M are qualified based on strict equivalence of the following critical parameters:

Electrical Parameters:

• Capacitance: 1 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Mounting Type: Surface Mount (exact match required)
• Package / Case: Radial, Can - SMD (exact match required)
• Size / Dimension: 0.157" Dia (4.00mm) (exact match required)
• Surface Mount Land Size: 0.169" L x 0.169" W (4.30mm x 4.30mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant or RoHS Compliant (acceptable)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts are grouped into two categories: Upgrade Manufacturer and Parametric Equivalent. Both categories meet all critical electrical and mechanical parameters. Differences in ESR, lifetime rating, and ripple current specifications are documented for engineering reference but do not disqualify substitution eligibility.

The MAL215371108E3 offers extended lifetime rating of 2000 hours at 105°C compared to 1000 hours for the 105SMH050M, and significantly lower ESR of 12 Ohm at 100 kHz. Both parts carry ROHS3 compliance and MSL 1 rating. The MAL215371108E3 is supplied in Tape & Reel packaging with 5952 pieces in current inventory.

SHT50V010M-D55 (Meritek) - Parametric Equivalent:

The SHT50V010M-D55 qualifies as a parametric equivalent substitute based on complete electrical and mechanical compatibility. This part matches all critical specifications: 1 µF capacitance, 50 V rating, ±20% tolerance, and identical surface mount package dimensions. The SHT50V010M-D55 maintains the same 1000-hour lifetime rating at 105°C as the 105SMH050M and operates across the identical temperature range. RoHS compliance is confirmed. ESR data is not specified for this part. The SHT50V010M-D55 is available with 1011 pieces in current inventory.

Both substitute parts are Active status products suitable for direct replacement in general purpose applications where the 105SMH050M is currently specified.

Frequently Asked Questions (FAQ)

Q: Can MAL215371108E3 be used as a direct replacement for 105SMH050M?

A: Yes. The MAL215371108E3 meets all critical electrical and mechanical parameters: 1 µF capacitance, 50 V voltage rating, ±20% tolerance, identical surface mount package dimensions (0.157" diameter, 4.30mm x 4.30mm land size), and identical operating temperature range (-55°C to 105°C). Both parts carry ROHS3 compliance and MSL 1 rating. The MAL215371108E3 offers improved performance with lower ESR and extended lifetime rating.

Q: Can SHT50V010M-D55 be used as a direct replacement for 105SMH050M?

A: Yes. The SHT50V010M-D55 meets all critical electrical and mechanical parameters: 1 µF capacitance, 50 V voltage rating, ±20% tolerance, identical surface mount package dimensions (0.157" diameter, 4.30mm x 4.30mm land size), and identical operating temperature range (-55°C to 105°C). Both parts carry RoHS compliance and MSL 1 rating with matching 1000-hour lifetime at 105°C.

Q: What is the difference in ESR between these parts?

A: The 105SMH050M specifies 198.94 Ohm ESR at 120 Hz. The MAL215371108E3 specifies 12 Ohm ESR at 100 kHz, indicating significantly lower impedance at higher frequencies. The SHT50V010M-D55 does not provide ESR specification. ESR differences reflect different measurement frequencies and internal construction but do not affect substitution eligibility for general purpose applications.

Q: Are there packaging differences between these parts?

A: The 105SMH050M is supplied in Bulk packaging. The MAL215371108E3 is supplied in Tape & Reel (TR) packaging. The SHT50V010M-D55 packaging type is not specified. All three parts use identical surface mount package dimensions and land sizes, ensuring PCB compatibility. Packaging format differences relate only to supply and handling, not electrical or mechanical performance.

Q: Do all three parts meet RoHS compliance?

A: Yes. The 105SMH050M and MAL215371108E3 are ROHS3 Compliant. The SHT50V010M-D55 is RoHS Compliant. Both compliance levels are acceptable for applications requiring RoHS certification.

Q: What is the lifetime difference between 105SMH050M and MAL215371108E3?

A: The 105SMH050M is rated for 1000 hours at 105°C. The MAL215371108E3 is rated for 2000 hours at 105°C. This represents extended operational life for the Vishay part under maximum temperature conditions. Both parts meet the same operating temperature range and are suitable for general purpose applications.

Q: Are the physical dimensions identical for all three parts?

A: Yes. All three parts share identical critical dimensions: 0.157" diameter (4.00mm), surface mount land size of 0.169" L x 0.169" W (4.30mm x 4.30mm), and identical mounting type (Surface Mount, Radial Can - SMD). The MAL215371108E3 has a slightly lower seated height of 0.209" (5.30mm) compared to 0.217" (5.50mm) for both the 105SMH050M and SHT50V010M-D55. This minor height difference does not affect PCB layout compatibility.
