DLR1D47J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DLR1D47J-F is a 4700 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 100V DC operation with polyester dielectric material. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and maintenance applications. The radial through-hole configuration and ±5% tolerance make this capacitor suitable for general-purpose filtering and coupling applications in electronic circuits.

Engineering Selection Recommendations

The 168472J100A-F serves as a direct electrical equivalent to the obsolete DLR1D47J-F. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Selection Basis:

The substitute part maintains identical electrical specifications (4700 pF capacitance, ±5% tolerance, 100V DC rating) and dielectric material classification (polyester). The metallized polyester construction of the 168472J100A-F provides equivalent performance with enhanced temperature operating range (-55°C to 125°C versus -40°C to 85°C).

Physical Considerations:

The 168472J100A-F exhibits different physical dimensions and lead spacing compared to the original part. PCB layout verification is required to confirm that the substitute component accommodates the available footprint space. The substitute part is smaller in overall height (0.256" versus 0.413") and has increased lead spacing (0.197" versus 0.138"), which may require PCB redesign or mechanical clearance assessment.

Compliance Status:

Both components maintain equivalent regulatory compliance. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 168472J100A-F directly replace the DLR1D47J-F without circuit modification?

A: Electrical substitution is direct. The capacitance, tolerance, voltage rating, and dielectric material are identical. Physical dimensions differ; PCB layout compatibility must be verified before implementation.

Q: What is the significance of the metallized polyester dielectric in the substitute part?

A: Metallized polyester construction is a standard polyester film variant that maintains equivalent electrical performance. This does not affect circuit functionality for general-purpose applications.

Q: Does the wider lead spacing of the 168472J100A-F affect compatibility?

A: Lead spacing is 0.197" (5.00mm) on the substitute versus 0.138" (3.50mm) on the original. This requires verification against PCB hole pattern spacing. If the original PCB was designed for 0.138" spacing, the substitute cannot be installed without PCB modification.

Q: Why is the operating temperature range wider on the substitute part?

A: The 168472J100A-F operates from -55°C to 125°C, compared to -40°C to 85°C for the DLR1D47J-F. This extended range does not affect substitution suitability; the substitute part remains functional across the original part's temperature specification.

Q: Is the substitute part available in the same packaging format?

A: Both parts are radial through-hole components with PC pin termination. The substitute is supplied in bulk packaging, whereas original packaging information for the DLR1D47J-F is not specified in the provided data.

Q: What compliance certifications apply to the substitute part?

A: The 168472J100A-F is ROHS3 compliant and REACH unaffected, matching the regulatory status of the original DLR1D47J-F.
