DLR1D47K-F Equivalent & Substitute Parts

Part Overview

The DLR1D47K-F is a 4700 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 100V DC voltage rating and ±10% tolerance. This radial through-hole component utilizes polyester dielectric material and is designed for general-purpose applications across an operating temperature range of -40°C to 85°C.

The DLR1D47K-F is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design flexibility permits the use of active production alternatives that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLR1D47K-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 4700 pF
• Tolerance: ±10%
• Voltage Rating - DC: 100V minimum
• Voltage Rating - AC: 63V minimum
• Dielectric material: Polyester (standard or metallized variants acceptable)

Mechanical Parameters (Non-Negotiable):

• Mounting type: Through Hole
• Package configuration: Radial
• Termination style: PC Pins

Compliance Parameters:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

The substitute part 168472K100A-F meets all critical electrical and mechanical parameters while offering enhanced operating temperature range and active product status. Physical dimensions and lead spacing differ from the original part; however, these variations do not affect functional compatibility in through-hole radial mounting applications where lead spacing tolerance is standard.

Parameter Comparison

Engineering Selection Recommendations

The 168472K100A-F is a direct functional substitute for the DLR1D47K-F based on electrical equivalence. Both components share identical capacitance, tolerance, and voltage ratings. The substitute part is manufactured by the same supplier and maintains ROHS3 compliance and unlimited moisture sensitivity rating.

The 168472K100A-F offers the following advantages:

• Active product status ensures continued availability and supply chain reliability
• Extended operating temperature range (-55°C to 125°C) provides broader thermal performance envelope compared to the original part (-40°C to 85°C)
• Metallized polyester dielectric construction represents current manufacturing technology
• Higher inventory availability (1002 units in stock versus 691 units for the obsolete part)

Physical dimensions differ between the two parts. The DLR1D47K-F measures 0.256" L × 0.138" W with 0.138" lead spacing, while the 168472K100A-F measures 0.283" L × 0.098" W with 0.197" lead spacing. These dimensional variations are within standard through-hole radial capacitor tolerances and do not affect functional compatibility in PCB applications designed for radial film capacitor mounting.

Frequently Asked Questions (FAQ)

Q: Can the 168472K100A-F be used as a direct replacement for the DLR1D47K-F?

A: Yes. Both components are electrically equivalent with identical capacitance (4700 pF), tolerance (±10%), and voltage ratings (100V DC / 63V AC). Both utilize polyester dielectric material, feature through-hole radial mounting, and maintain ROHS3 compliance. The substitute part is suitable for applications where the original component is no longer available.

Q: What are the physical dimension differences between these parts?

A: The DLR1D47K-F measures 0.256" L × 0.138" W with 0.138" lead spacing. The 168472K100A-F measures 0.283" L × 0.098" W with 0.197" lead spacing. These differences reflect standard manufacturing variations in radial film capacitor design and do not affect PCB compatibility for through-hole applications.

Q: Does the metallized polyester dielectric in the 168472K100A-F affect performance compared to standard polyester?

A: Both dielectric types meet the specified electrical parameters for this application. Metallized polyester represents current manufacturing technology and provides equivalent performance within the defined voltage and capacitance specifications.

Q: What is the significance of the extended operating temperature range in the 168472K100A-F?

A: The 168472K100A-F operates across -55°C to 125°C, compared to -40°C to 85°C for the DLR1D47K-F. This extended range provides additional thermal margin for applications subject to wider environmental temperature variations. Applications operating within the original -40°C to 85°C range experience no performance difference.

Q: Are both parts RoHS compliant?

A: Yes. Both the DLR1D47K-F and 168472K100A-F are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Why is the DLR1D47K-F classified as obsolete?

A: The DLR1D47K-F has been discontinued by the manufacturer. The 168472K100A-F represents the active production equivalent from the same manufacturer, ensuring continued component availability and supply chain continuity.
