Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLR1D22J-F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 2200 pF (exact match required)
• Tolerance: ±5% (electrical performance equivalence)
• Voltage Rating (DC): 100V minimum (safety and reliability requirement)
• Voltage Rating (AC): 63V minimum (operational requirement)
• Dielectric Material: Polyester (functional equivalence)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package Type: Radial (mechanical fit requirement)
• Termination: PC Pins (solder connection compatibility)

Compliance Parameters:

• RoHS3 Compliant status (regulatory requirement)
• REACH Unaffected status (regulatory requirement)

The substitute part 168222J100A-F meets all mandatory matching parameters and compliance requirements. Physical dimensions and lead spacing differ from the original part; however, these variations remain within acceptable tolerances for through-hole radial mounting applications.

Engineering Selection Recommendations

Primary Substitute: 168222J100A-F

The 168222J100A-F is the direct functional equivalent for the obsolete DLR1D22J-F. Selection of this substitute is based on the following engineering criteria:

1. Electrical Equivalence: Identical capacitance (2200 pF), tolerance (±5%), and voltage ratings (100V DC / 63V AC) ensure direct functional replacement in circuit applications.

2. Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying current environmental and safety standards.

3. Active Product Status: The 168222J100A-F is classified as active, ensuring long-term availability and supply chain continuity compared to the obsolete DLR1D22J-F.

4. Enhanced Operating Range: The substitute part operates across -55°C to +125°C, exceeding the original part's -40°C to +85°C range, providing superior thermal performance margin.

5. Metallized Polyester Dielectric: The substitute uses metallized polyester dielectric, which is functionally compatible with standard polyester applications while offering improved performance characteristics.

Physical Dimension Considerations: The substitute part exhibits dimensional variations in length, width, height, and lead spacing. PCB layout verification is required to confirm mechanical fit within the available mounting space. Lead spacing increases from 3.50mm to 5.00mm; board-level hole pattern compatibility must be confirmed prior to implementation.

Frequently Asked Questions (FAQ)

Q1: Can the 168222J100A-F directly replace the DLR1D22J-F without circuit modification?

A: Yes, from an electrical standpoint. The 168222J100A-F provides identical capacitance, tolerance, and voltage ratings. However, physical dimensions differ; PCB layout verification is required to confirm the substitute fits within the available mounting space and hole pattern.

Q2: What is the significance of the metallized polyester dielectric in the substitute part?

A: Metallized polyester dielectric is functionally equivalent to standard polyester for general-purpose applications. The metallization provides self-healing properties under electrical stress, which can enhance reliability in certain operating conditions.

Q3: Does the wider operating temperature range of the 168222J100A-F affect circuit performance?

A: The substitute's extended temperature range (-55°C to +125°C versus -40°C to +85°C) provides additional operational margin. This does not negatively affect performance within the original part's specified range and may improve reliability in temperature-variable environments.

Q4: Are there lead spacing compatibility issues between the two parts?

A: Yes. The DLR1D22J-F has 3.50mm lead spacing while the 168222J100A-F has 5.00mm lead spacing. The PCB hole pattern must accommodate the wider spacing. If the original board layout cannot be modified, alternative substitutes with matching lead spacing must be evaluated.

Q5: What is the inventory status for the substitute part?

A: The 168222J100A-F has 907 pieces in stock as new original inventory, ensuring immediate availability for procurement and implementation.

Q6: Are both parts compliant with current environmental regulations?

A: Yes. Both the DLR1D22J-F and 168222J100A-F are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards for electronic component manufacturing and use.
