Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DLR1D1J-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 1000 pF (exact match)
• Tolerance: ±5% (exact match)
• Voltage rating: 100V DC minimum / 63V AC minimum
• Dielectric material: Polyester construction

Mechanical Equivalence Requirements:

• Mounting technology: Through-hole radial configuration
• Termination style: PC pins for PCB insertion
• Compliance certifications: ROHS3 and REACH status alignment

The substitute part 168102J100A-F meets all electrical and mechanical equivalence criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 168102J100A-F

The 168102J100A-F is the direct functional equivalent for DLR1D1J-F applications. Both components share identical electrical specifications (1000 pF, ±5%, 100V DC, 63V AC) and polyester dielectric construction with through-hole radial mounting.

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production environments.

Product Status Advantage: The 168102J100A-F carries active product status with 7924 units in stock, compared to the obsolete DLR1D1J-F with limited remaining inventory (638 units). This ensures long-term supply chain viability.

Physical Considerations: The substitute exhibits different physical dimensions and lead spacing (0.197" versus 0.138"). PCB layout verification is required to confirm mechanical fit within existing footprints. The substitute's expanded operating temperature range (-55°C to 125°C versus -40°C to 85°C) provides enhanced thermal performance margin.

Dielectric Enhancement: The 168102J100A-F employs metallized polyester construction, which may offer improved performance characteristics compared to standard polyester in the original part.

Frequently Asked Questions (FAQ)

Q: Can 168102J100A-F directly replace DLR1D1J-F in existing PCB designs?

A: Electrical substitution is valid. However, physical lead spacing differs (5.00mm versus 3.50mm), requiring PCB layout verification before implementation. Hole positioning and trace routing must accommodate the wider lead spacing.

Q: What is the significance of metallized polyester versus standard polyester dielectric?

A: Both constructions meet the specified electrical parameters. Metallized polyester in the 168102J100A-F represents a manufacturing variant within the polyester category and does not alter functional equivalence for general-purpose applications.

Q: Are there inventory implications for selecting the substitute?

A: Yes. The 168102J100A-F has 7924 units in stock versus 638 units for the obsolete DLR1D1J-F. For production quantities exceeding remaining DLR1D1J-F inventory, the substitute ensures supply continuity.

Q: Does the expanded operating temperature range of 168102J100A-F affect circuit design?

A: No. The substitute's wider temperature range (-55°C to 125°C) exceeds the original specification (-40°C to 85°C), providing additional thermal margin without requiring design modification.

Q: What compliance certifications apply to both parts?

A: Both DLR1D1J-F and 168102J100A-F are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and distribution.

Q: Is lead spacing the only physical difference between these parts?

A: Lead spacing (3.50mm versus 5.00mm) and overall dimensions differ. The substitute is slightly larger (7.20mm L x 2.50mm W versus 6.00mm L x 3.50mm W) with reduced seated height (6.50mm versus 10.50mm). PCB footprint compatibility must be confirmed.
