Substitute Part Grouping Explanation

Substitution of the SN010M050ST is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 1 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 50 V (exact match required)
• Polarization: Bi-Polar (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Ripple Current @ Low Frequency: 17 mA @ 120 Hz (exact match required)

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.079" (2.00mm) (exact match required)
• Size / Dimension: 0.197" Dia (5.00mm) (exact match required)
• Height - Seated (Max): 0.433" (11.00mm) (exact match required)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (exact match required)

The UVP1H010MDD manufactured by Nichicon meets all substitution criteria and is identified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The UVP1H010MDD is a direct functional equivalent to the SN010M050ST. Both components are classified as obsolete and meet ROHS3 compliance requirements. Selection between these parts is based on availability and supply chain considerations rather than electrical or mechanical differences.

The UVP1H010MDD demonstrates extended lifetime specifications (2000 Hrs @ 85°C versus 1000 Hrs @ 85°C for the original part), indicating improved reliability characteristics within the same electrical and mechanical envelope. This extended operational life does not alter substitution eligibility but provides additional performance margin in applications requiring extended service intervals.

Both components are suitable for direct board-level replacement without circuit redesign or PCB modification.

Frequently Asked Questions (FAQ)

Q: Can the UVP1H010MDD replace the SN010M050ST in existing designs?

A: Yes. The UVP1H010MDD is electrically and mechanically equivalent to the SN010M050ST. All critical parameters including capacitance, voltage rating, polarization, operating temperature range, and physical dimensions are identical. Direct substitution is possible without circuit modification.

Q: Are there any differences in ESR (Equivalent Series Resistance) between these parts?

A: The SN010M050ST specifies ESR at 159.24 Ohm @ 120 Hz. The UVP1H010MDD does not provide ESR specification in the available data. Both parts meet the same ripple current requirement of 17 mA @ 120 Hz, confirming functional equivalence for general-purpose applications.

Q: What is the significance of the extended lifetime rating on the UVP1H010MDD?

A: The UVP1H010MDD is rated for 2000 Hrs @ 85°C compared to 1000 Hrs @ 85°C for the SN010M050ST. This indicates improved capacitor longevity under thermal stress. Both ratings are provided by manufacturers for reference; actual service life depends on application-specific operating conditions.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN010M050ST and UVP1H010MDD are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the lead spacing and can these parts be used interchangeably on existing PCBs?

A: Both parts feature 0.079" (2.00mm) lead spacing and identical physical dimensions (0.197" diameter, 0.433" maximum height). They are pin-compatible and can be used interchangeably on PCBs designed for radial, through-hole aluminum electrolytic capacitors with these specifications.
