Engineering Selection Recommendations

The 160474J100E-F is a direct functional equivalent to the DLR1P47J-F for applications requiring a 0.47 µF, 100V DC polyester film capacitor with radial through-hole mounting. Selection of the 160474J100E-F is supported by the following factors:

Product Status: The 160474J100E-F is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete DLR1P47J-F.

Electrical Equivalence: Both parts maintain identical capacitance, tolerance, voltage ratings, and lead spacing specifications. The metallized polyester dielectric in the 160474J100E-F is a standard evolution of polyester film capacitor technology and is electrically equivalent for general-purpose applications.

Compliance Alignment: Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Temperature Performance: The 160474J100E-F operates across an extended temperature range (-55°C to +105°C) compared to the DLR1P47J-F (-40°C to +85°C), providing enhanced thermal margin for applications operating at temperature extremes.

Physical Compatibility: Identical lead spacing (0.394" / 10.00 mm) and radial through-hole configuration ensure direct PCB footprint compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 160474J100E-F be used as a direct replacement for the DLR1P47J-F on existing PCBs?

A: Yes. Both parts share identical lead spacing (0.394" / 10.00 mm), radial package configuration, and PC pin termination. No PCB layout changes are required for substitution.

Q: What is the difference between polyester and metallized polyester dielectric materials?

A: Metallized polyester film uses a thin metal coating applied to the polyester substrate, reducing physical size while maintaining electrical performance. For the specified 0.47 µF, 100V DC application, both dielectric types are electrically equivalent.

Q: Does the extended operating temperature range of the 160474J100E-F affect circuit performance?

A: The extended temperature range (-55°C to +105°C versus -40°C to +85°C) represents an enhancement in thermal capability. Circuit performance remains equivalent within the original DLR1P47J-F operating range.

Q: Are there any compliance or certification differences between these parts?

A: Both parts carry identical RoHS3 compliance and REACH unaffected status. No compliance differences exist for regulatory or procurement purposes.

Q: What is the significance of the different part number series (DLR versus 160)?

A: The series designation reflects internal CDE product line organization. The 160 series represents current production technology, while the DLR series is obsolete. Both series maintain equivalent electrical and mechanical specifications for this capacitance and voltage rating.

Q: Can the 160474J100E-F be used in applications originally designed for the DLR1P47J-F?

A: Yes. Identical electrical ratings, tolerance, voltage specifications, and physical mounting configuration ensure functional equivalence across all general-purpose applications within the specified operating parameters.
