Engineering Selection Recommendations

The 168152J100A-F represents a direct electrical and functional substitute for the obsolete DLR1D15J-F. Both components maintain identical capacitance, tolerance, and voltage ratings with equivalent polyester dielectric construction. The substitute part carries active product status with higher inventory availability (2112 pcs vs. 1002 pcs).

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Temperature Performance: The 168152J100A-F provides an extended operating temperature range (-55°C to 125°C) compared to the original part (-40°C to 85°C), offering improved thermal performance margins in applications requiring wider temperature operation.

Physical Considerations: The substitute part exhibits different physical dimensions and lead spacing. PCB layout modifications are required to accommodate the 0.197" (5.00mm) lead spacing of the 168152J100A-F versus the 0.138" (3.50mm) spacing of the DLR1D15J-F. The substitute part is also more compact in height (0.256" vs. 0.413"), which may provide space advantages in constrained layouts.

Availability: Selection of the 168152J100A-F is supported by higher current inventory levels and active manufacturing status, ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the 168152J100A-F be used as a direct replacement for the DLR1D15J-F without circuit modification?

A: Electrical substitution is direct. However, physical layout modification is required due to different lead spacing (5.00mm vs. 3.50mm) and component dimensions. PCB drilling and trace routing must be adjusted accordingly.

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

A: Metallized polyester construction in the 168152J100A-F maintains functional equivalence with the standard polyester dielectric of the DLR1D15J-F. Both configurations deliver the specified 1500 pF capacitance and 100V DC rating. Metallized construction may offer improved volumetric efficiency, contributing to the more compact physical profile.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain identical RoHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution.

Q: Why does the substitute part have a wider operating temperature range?

A: The 168152J100A-F is specified for -55°C to 125°C operation, exceeding the original part's -40°C to 85°C range. This represents a design improvement in the active substitute part and provides additional thermal margin for applications operating at temperature extremes.

Q: What is the impact of different lead spacing on circuit board design?

A: Lead spacing differences (3.50mm original vs. 5.00mm substitute) require PCB redesign. Hole positions must be relocated, and trace routing adjusted. This is a mechanical design consideration, not an electrical limitation.

Q: Is the substitute part suitable for high-reliability applications?

A: Both parts carry ROHS3 compliance and equivalent electrical specifications. Selection suitability depends on application-specific reliability requirements and qualification procedures established by the end user.
