Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN010M025ST is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Capacitance: 1 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: Minimum 25 V (equal or higher acceptable)
• Polarization: Bi-Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.079" (2.00 mm) for direct PCB compatibility
• Diameter: 0.197" (5.00 mm) (exact match required)

Acceptable Variations:

• Voltage Rating: Higher voltage ratings (50 V) are acceptable as they provide improved reliability margin
• Lifetime @ Temperature: Higher values indicate improved performance characteristics
• ESR: Lower values indicate improved performance
• Height - Seated: Minor variations acceptable if within PCB layout constraints

The substitute parts UVP1H010MDD and UVP1H010MDD1TD meet all critical electrical parameters. Both are manufactured by Nichicon and share identical capacitance, tolerance, polarization, and mounting specifications. The primary difference between these substitutes is packaging format (Bulk vs. Cut Tape) and minor mechanical variations in lead spacing and height.

Parameter Comparison

Engineering Selection Recommendations

UVP1H010MDD (Upgrade Substitute):

This part is classified as an upgrade substitute due to its higher voltage rating (50 V vs. 25 V) and doubled lifetime specification (2000 Hrs @ 85°C vs. 1000 Hrs @ 85°C). Both components are ROHS3 compliant and share identical capacitance, tolerance, and polarization characteristics. The UVP1H010MDD maintains the same lead spacing (0.079" / 2.00 mm) and diameter (0.197" / 5.00 mm) as the original SN010M025ST, ensuring direct PCB footprint compatibility. The increased voltage rating provides additional design margin and improved reliability in applications where the original 25 V specification is adequate. Bulk packaging is suitable for production environments with established supply chain processes.

UVP1H010MDD1TD (Similar Substitute):

This part is classified as a similar substitute with identical electrical specifications to the UVP1H010MDD but differs in packaging format (Cut Tape vs. Bulk) and mechanical dimensions. The lead spacing is increased to 0.098" (2.50 mm) and the seated height is increased to 0.492" (12.50 mm). These dimensional variations require PCB layout verification before implementation. The Cut Tape packaging format is suitable for automated assembly processes and lower-volume applications. Like the UVP1H010MDD, this part provides 50 V voltage rating and 2000 Hrs @ 85°C lifetime, with ROHS3 compliance and identical electrical performance.

Selection Criteria:

Both Nichicon substitutes are acceptable replacements based on compliance certifications (ROHS3, EAR99) and electrical equivalence. Selection between UVP1H010MDD and UVP1H010MDD1TD depends on packaging requirements and PCB layout constraints. The increased lead spacing and height of the UVP1H010MDD1TD require verification against existing PCB designs before substitution.

Frequently Asked Questions (FAQ)

Q: Can the UVP1H010MDD be used as a direct replacement for the SN010M025ST?

A: The UVP1H010MDD is electrically compatible as a direct replacement. Both components share identical capacitance (1 µF), tolerance (±20%), polarization (Bi-Polar), and lead spacing (0.079" / 2.00 mm). The higher voltage rating (50 V vs. 25 V) and extended lifetime (2000 Hrs vs. 1000 Hrs @ 85°C) provide improved performance margins. PCB footprint compatibility is confirmed for standard through-hole mounting.

Q: What is the difference between UVP1H010MDD and UVP1H010MDD1TD?

A: Both parts are electrically identical with 1 µF capacitance, ±20% tolerance, and 50 V voltage rating. The primary differences are packaging format and mechanical dimensions. UVP1H010MDD is supplied in Bulk packaging, while UVP1H010MDD1TD is supplied in Cut Tape (CT) format. The UVP1H010MDD1TD has increased lead spacing (0.098" vs. 0.079") and greater seated height (0.492" vs. 0.433"). These dimensional variations require PCB layout verification.

Q: Are the substitute parts ROHS3 compliant?

A: Both UVP1H010MDD and UVP1H010MDD1TD are ROHS3 compliant, matching the compliance status of the original SN010M025ST. All three components are classified as EAR99 for export purposes.

Q: What is the impact of the higher voltage rating on circuit performance?

A: The 50 V rating of the substitute parts (vs. 25 V original) provides additional design margin and improved reliability. In applications where the circuit voltage does not exceed 25 V, the higher voltage rating does not negatively impact performance. The capacitance and tolerance remain identical, ensuring equivalent electrical behavior in the circuit.

Q: Can I use these substitutes in high-ripple-current applications?

A: The substitute parts specify ripple current ratings: 17 mA @ 120 Hz and 34 mA @ 10 kHz. The original SN010M025ST does not provide ripple current specifications. Applications requiring ripple current handling should verify that the specified values meet circuit requirements before implementation.

Q: What are the inventory considerations for these substitutes?

A: The UVP1H010MDD has 9598 pieces in stock (Bulk packaging), and the UVP1H010MDD1TD has 10357 pieces in stock (Cut Tape packaging). Both parts are classified as obsolete, consistent with the original component status. Inventory availability should be confirmed with the supplier before finalizing procurement decisions.

Q: Are there any temperature range differences between the main part and substitutes?

A: All three components operate across the identical temperature range of -40°C to 85°C. No temperature performance differences exist between the SN010M025ST and the Nichicon substitutes.
