Substitute Part Grouping Explanation

Substitution of the DLR1S47J-F is determined by the following critical parameters:

Mandatory Match Criteria:

Capacitance value: 0.047 µF (exact)
Voltage rating: 100V DC minimum
Tolerance: ±5% or tighter
Lead spacing: 0.197" (5.00mm) for PCB hole alignment
Mounting type: Through Hole Radial configuration
Dielectric: Polyester film technology

Allowable Variations:

Physical dimensions may differ provided lead spacing remains constant
Operating temperature range may be extended (wider range acceptable)
Dielectric construction may be enhanced (e.g., metallized polyester)
Regulatory compliance must be maintained (ROHS3, REACH)

The substitute part 168473J100C-F satisfies all mandatory criteria while offering enhanced specifications in operating temperature range and dielectric construction.

Engineering Selection Recommendations

Primary Substitute: 168473J100C-F

The 168473J100C-F is the direct functional equivalent for the obsolete DLR1S47J-F. Selection of this substitute is based on the following engineering factors:

Electrical Equivalence: Identical capacitance (0.047 µF), voltage rating (100V DC), and tolerance (±5%) ensure circuit performance parity.
Physical Compatibility: Lead spacing of 0.197" (5.00mm) and radial through-hole configuration maintain PCB layout compatibility without requiring board redesign.
Product Status: The 168473J100C-F is in active production with 2609 units in stock, ensuring long-term availability compared to the obsolete DLR1S47J-F.
Enhanced Specifications: The substitute offers an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) and metallized polyester dielectric construction, providing improved performance margins in demanding applications.
Regulatory Compliance: Both ROHS3 and REACH compliance are maintained, satisfying current environmental and safety standards.
Dimensional Advantage: The substitute features a more compact physical footprint (7.20mm x 2.50mm versus 9.50mm x 5.00mm), which may provide layout benefits in space-constrained designs while maintaining identical lead spacing.

Frequently Asked Questions (FAQ)

Q: Can the 168473J100C-F be used as a direct replacement for the DLR1S47J-F without circuit modification?

A: Yes. The substitute part maintains identical electrical specifications (0.047 µF, 100V DC, ±5% tolerance) and lead spacing (5.00mm), enabling direct PCB substitution without circuit redesign or board layout changes.

Q: What is the primary difference between these two capacitors?

A: The main differences are product status and dielectric construction. The DLR1S47J-F uses standard polyester film, while the 168473J100C-F uses metallized polyester film. The substitute also offers an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) and is in active production rather than obsolete.

Q: Does the metallized polyester dielectric in the 168473J100C-F affect circuit performance?

A: Metallized polyester is a standard enhancement in film capacitor technology that maintains the same electrical characteristics while improving reliability and performance margins. No circuit behavior changes occur with this substitution.

Q: Are there any packaging or inventory considerations?

A: The DLR1S47J-F is obsolete with limited stock (892 units). The 168473J100C-F is in active production with significantly higher availability (2609 units), making it the preferred choice for new designs and ongoing production requirements.

Q: Will the smaller physical dimensions of the 168473J100C-F affect PCB assembly?

A: No. The critical parameter for PCB compatibility is lead spacing (0.197" / 5.00mm), which is identical in both parts. The smaller overall dimensions of the substitute may actually provide layout advantages without any assembly complications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DLR1S47J-F and 168473J100C-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
