Substitute Part Grouping Explanation

Substitution of the TE1303 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 5 µF (exact match required)
• Voltage rating: 50 V (exact match required)
• Tolerance specification: -10%, +75% (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Lifetime rating: 2000 Hrs @ 85°C (exact match required)
• Package configuration: Axial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Physical dimensions: 0.248" Dia x 0.689" L / 6.30mm x 17.50mm (exact match required)
• Polarization: Polar (exact match required)

The substitute part TE1303-E3 meets all electrical and mechanical parameters specified for the TE1303, providing direct interchangeability for component selection and procurement.

Parameter Comparison

Engineering Selection Recommendations

Both TE1303 and TE1303-E3 are electrically and mechanically equivalent for general-purpose applications. Selection between these parts should be based on regulatory and compliance requirements:

The TE1303-E3 is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS3 regulations or where compliance documentation is required. The TE1303 is RoHS non-compliant and should be selected only where RoHS compliance is not a requirement.

Both parts carry the same ECCN (EAR99) and HTSUS classification (8532.22.0020), indicating equivalent export and tariff treatment.
