Engineering Selection Recommendations

The 160334J100E-F is a direct functional equivalent to the DLR1P33J-F for applications requiring 0.33 µF capacitance at 100V DC with ±5% tolerance in through-hole radial configuration.

Selection Basis:

Electrical Compatibility: Both parts maintain identical capacitance, tolerance, and voltage ratings. The substitute's metallized polyester dielectric is compatible with polyester applications.
Thermal Performance: The substitute part operates across an extended temperature range (-55°C to 105°C) compared to the original (-40°C to 85°C), providing superior thermal margin for demanding environments.
Product Availability: The substitute is actively manufactured with 1470 units in stock versus the obsolete DLR1P33J-F with limited remaining inventory (816 units).
Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting modern procurement requirements.
Physical Footprint: The substitute occupies a smaller board space (13.00mm x 6.00mm versus 16.50mm x 9.50mm) and reduced height (12.00mm versus 19.50mm), offering layout advantages without functional compromise.
Lead Spacing Preservation: Identical 0.394" (10.00mm) lead spacing ensures direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 160334J100E-F replace the DLR1P33J-F in existing designs?

A: Yes. Both parts share identical electrical specifications (0.33 µF, ±5%, 100V DC) and mechanical configuration (through-hole radial, 10.00mm lead spacing, PC pins). The substitute's smaller physical dimensions and extended temperature range present no functional limitations for direct substitution.

Q: What is the difference between polyester and metallized polyester dielectric?

A: Both are polyester-based dielectrics suitable for general-purpose applications. Metallized polyester features a thin metal layer that provides self-healing properties in certain failure modes. For the specified 0.33 µF, 100V application, both dielectric types are functionally equivalent.

Q: Will the smaller size of the 160334J100E-F affect PCB layout?

A: The substitute's reduced dimensions (13.00mm x 6.00mm versus 16.50mm x 9.50mm) and lower height (12.00mm versus 19.50mm) occupy less board space. Lead spacing remains identical at 10.00mm, ensuring existing PCB footprints accommodate the substitute without modification. Reduced height may improve clearance in space-constrained applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the DLR1P33J-F and 160334J100E-F are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the MSL rating difference?

A: The DLR1P33J-F lists MSL as Not Applicable, while the 160334J100E-F carries MSL 1 (Unlimited). MSL 1 indicates the component has no moisture sensitivity limitations and requires no special storage or handling precautions.

Q: Which part should be selected for new designs?

A: The 160334J100E-F is the appropriate selection for new designs due to active product status, superior availability, extended operating temperature range, and compliance with current manufacturing standards. The DLR1P33J-F should be reserved for legacy system maintenance only.
