Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLR1D15K-F is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Criteria:

• Capacitance value: 1500 pF (exact match required)
• Voltage rating: 100V DC minimum
• Dielectric material: Polyester-based film
• Mounting configuration: Through-hole radial
• Termination style: PC pins
• Compliance standards: ROHS3 and REACH requirements

The substitute part 168152J100A-F meets all mandatory criteria. While this substitute exhibits improved tolerance (±5% versus ±10%) and extended operating temperature range (-55°C to +125°C versus -40°C to +85°C), these represent performance enhancements rather than deviations from the original specification. The substitute maintains identical capacitance, voltage rating, dielectric material, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The 168152J100A-F is a direct functional substitute for the obsolete DLR1D15K-F. Selection of this substitute is supported by the following engineering factors:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements for electronic component procurement.

Product Availability: The DLR1D15K-F is classified as obsolete with limited inventory (940 units). The substitute 168152J100A-F is active in production with substantially higher inventory availability (2112 units), providing long-term procurement security.

Electrical Equivalence: Identical capacitance (1500 pF), voltage ratings (100V DC / 63V AC), and dielectric material ensure electrical performance equivalence in circuit applications.

Physical Compatibility: Both components utilize through-hole radial mounting with PC pin termination, permitting direct board-level substitution without PCB redesign or layout modification.

Performance Enhancement: The substitute offers tighter tolerance (±5% versus ±10%) and extended operating temperature range (-55°C to +125°C versus -40°C to +85°C), providing improved performance margins in temperature-sensitive or precision-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the 168152J100A-F be used as a direct replacement for the DLR1D15K-F without PCB modification?

A: Yes. Both components share identical capacitance, voltage ratings, mounting type (through-hole radial), and PC pin termination. Direct substitution on the PCB is possible without layout changes.

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

A: Metallized polyester film provides enhanced performance characteristics compared to standard polyester, including improved capacitance stability and self-healing properties. This represents a performance upgrade while maintaining electrical equivalence.

Q: Does the tighter tolerance (±5%) of the substitute affect circuit compatibility?

A: No. The substitute's ±5% tolerance is within the acceptable range for applications designed for the original ±10% tolerance. Tighter tolerance represents an improvement that does not compromise compatibility.

Q: Are there physical dimension differences between these parts?

A: Yes. The substitute (168152J100A-F) has different physical dimensions: 0.283" L x 0.098" W with 0.256" seated height and 0.197" lead spacing, compared to the main part's 0.236" L x 0.138" W with 0.413" seated height and 0.138" lead spacing. PCB footprint verification is required before substitution.

Q: What is the lead spacing difference and does it affect board compatibility?

A: The main part has 0.138" (3.50mm) lead spacing; the substitute has 0.197" (5.00mm) lead spacing. This difference requires verification against the PCB hole pattern. If the original PCB was designed for 3.50mm spacing, the 5.00mm spacing substitute will not fit without PCB modification.

Q: Is the extended temperature range of the substitute (-55°C to +125°C) beneficial for all applications?

A: Extended temperature range provides operational margin in temperature-sensitive environments. For applications operating within the original range (-40°C to +85°C), this enhancement is not required but does not introduce compatibility issues.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement and use.
