Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLR1S68J-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 0.068 µF (exact match)
• Tolerance: ±5% (matching tolerance band)
• Voltage rating: 100V DC minimum (equal or higher acceptable)
• Dielectric material: Polyester (same material family)

Mechanical Equivalence Requirements:

• Mounting type: Through Hole (radial configuration)
• Termination style: PC Pins (compatible with PCB insertion)
• Lead spacing: Within acceptable tolerance for standard 0.1" grid spacing

Compliance Requirements:

• RoHS3 compliance (environmental regulation alignment)
• REACH unaffected status (chemical regulation compliance)

The substitute part 167683J100A-F meets all electrical equivalence criteria while offering enhanced operating temperature range and reduced physical footprint. Both parts share identical capacitance, tolerance, voltage rating, and dielectric material specifications.

Parameter Comparison

Engineering Selection Recommendations

The 167683J100A-F qualifies as a direct electrical substitute for the obsolete DLR1S68J-F based on matched capacitance, tolerance, voltage rating, and dielectric material specifications. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The substitute part offers operational advantages through extended temperature range (-55°C to 125°C versus -40°C to 85°C) and reduced physical footprint, making it suitable for space-constrained applications. The metallized polyester dielectric in the substitute part provides equivalent electrical performance within the specified tolerance band.

Lead spacing differs by 0.50mm (7.00mm versus 7.50mm), which remains compatible with standard through-hole PCB layouts designed for 0.1" grid spacing. Physical dimension reduction in the substitute part presents no functional impediment and may provide layout optimization benefits.

Product status transition from obsolete (DLR1S68J-F) to active (167683J100A-F) ensures long-term availability and supply chain continuity for new designs and production support.

Frequently Asked Questions (FAQ)

Q: Can the 167683J100A-F directly replace the DLR1S68J-F in existing circuit designs?

A: Yes. Both parts share identical electrical specifications: 0.068 µF capacitance, ±5% tolerance, 100V DC rating, and polyester dielectric material. Through-hole radial mounting and PC pin termination are equivalent. Lead spacing difference of 0.50mm is within acceptable tolerance for standard PCB grid layouts.

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

A: Metallized polyester dielectric provides equivalent electrical performance to standard polyester film within the specified tolerance band. This construction method enables the reduced physical dimensions of the substitute part while maintaining electrical characteristics.

Q: Does the smaller physical size of the 167683J100A-F affect PCB layout compatibility?

A: No. The reduced dimensions (10.50mm x 3.50mm versus 10.50mm x 6.00mm) and lower seated height (7.00mm versus 12.50mm) present no compatibility issues. Lead spacing remains within acceptable tolerance for standard through-hole PCB designs. The smaller footprint may provide layout optimization benefits.

Q: Are both parts compliant with current environmental and chemical regulations?

A: Yes. Both the DLR1S68J-F and 167683J100A-F are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the advantage of the extended operating temperature range in the substitute part?

A: The 167683J100A-F operates across -55°C to 125°C, compared to -40°C to 85°C for the original part. This extended range provides design flexibility for applications requiring operation in wider temperature environments, though both parts are suitable for standard industrial and consumer applications within their respective ranges.

Q: Is the lead spacing difference between the two parts a concern for PCB design?

A: No. The 0.50mm difference (7.00mm versus 7.50mm) is minor and compatible with standard 0.1" (2.54mm) grid spacing used in through-hole PCB layouts. Both parts fit standard radial capacitor footprints without modification.
