Substitute Part Grouping Explanation

Substitution of the USW1V100MDD1TP is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 10 µF (exact match required)
• Voltage rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.059" (1.50mm) (exact match required)
• Physical dimensions: 0.157" Dia (4.00mm), Height 0.315" (8.00mm) (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)

The ESRG350ETD100MD07D from Chemi-Con meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ESRG350ETD100MD07D is a qualified substitute for the USW1V100MDD1TP based on electrical and mechanical parameter equivalence. The substitute part offers extended lifetime rating (2000 hours at 85°C versus 1000 hours), providing improved reliability margins in the same physical footprint. Both parts maintain RoHS compliance and REACH unaffected status. The substitute part carries active product status, ensuring continued availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the ESRG350ETD100MD07D be used as a direct replacement for the USW1V100MDD1TP?

A: Yes. Both parts share identical electrical specifications (10 µF, 35 V, ±20% tolerance), polarization (polar), and physical dimensions (0.157" diameter, 0.315" height, 0.059" lead spacing). Through-hole mounting compatibility is confirmed.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Nichicon versus Chemi-Con), product status (obsolete versus active), and rated lifetime (1000 hours versus 2000 hours at 85°C). Ripple current specifications are equivalent within measurement tolerance.

Q: Does the longer lifetime rating of the substitute part affect circuit design?

A: No. The substitute part meets or exceeds all electrical and mechanical requirements of the original part. The extended lifetime represents improved component reliability without requiring design modifications.

Q: Are there packaging differences?

A: The original part uses standard packaging, while the substitute is supplied in Tape & Box format. Both are through-hole components with identical lead spacing and physical dimensions suitable for PCB assembly.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.22.0020.
