• Current Rating: 11.4 A (identical specification)
• Current - Saturation: 60 A (identical specification)
• DC Resistance: 5 mOhm Max (identical specification)
• Inductance Tolerance: ±15% (identical specification)

Mechanical & Physical Parameters:

• Core Type: Drum Core, Wirewound (identical specification)
• Shielding: Unshielded (identical specification)
• Mounting Type: Through Hole (identical specification)
• Package / Case: Radial, Vertical Cylinder (identical specification)
• Physical Dimensions: 0.772" Dia (19.60 mm), Height 0.831" (21.10 mm) (identical specification)

Environmental Parameters:

All substitute parts maintain identical electrical performance, physical form factor, and environmental operating conditions, ensuring direct interchangeability within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the DC780-332L and DC780R-332L are active production components from API Delevan Inc. with identical electrical and mechanical specifications. The primary distinction between these parts is regulatory compliance status.

DC780-332L is RoHS non-compliant and should be selected for applications where existing assembly processes or legacy designs require non-compliant components, or where customer specifications explicitly permit such materials.

DC780R-332L is ROHS3 compliant and is the preferred selection for new designs and applications subject to RoHS Directive 2011/65/EU compliance requirements. This part is suitable for electronics manufacturing in regions with mandatory RoHS compliance standards.

Both parts maintain identical REACH and ECCN classifications. Selection between these parts should be based solely on project compliance requirements and regulatory jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can DC780R-332L replace DC780-332L in existing designs? A: Yes. Both parts share identical electrical specifications (3.3 µH inductance, 11.4 A current rating, 5 mOhm DCR), saturation current (60 A), physical dimensions (0.772" diameter, 0.831" height), and operating temperature range (-55°C to 125°C). Direct substitution is permissible from an electrical and mechanical standpoint. Regulatory compliance status must be confirmed with design and procurement requirements.

Q: What is the difference between DC780-332L and DC780R-332L? A: The DC780R-332L is ROHS3 compliant, while the DC780-332L is RoHS non-compliant. All other electrical, mechanical, and environmental parameters are identical. Selection depends on compliance requirements for the application.

Q: Are physical dimensions identical between these parts? A: Yes. Both parts have a diameter of 0.772" (19.60 mm) and maximum seated height of 0.831" (21.10 mm). PCB layout and mounting considerations are identical.

Q: What core material is used in these inductors? A: Both parts utilize ferrite core material in a drum core, wirewound configuration. The unshielded design is suitable for applications where EMI coupling with adjacent components is acceptable or desired.

Q: What is the saturation current specification? A: Both parts have a saturation current (Isat) of 60 A, allowing operation at the 11.4 A continuous current rating with substantial headroom before saturation occurs.

Q: Can these parts be used interchangeably in high-frequency applications? A: Both parts are specified with an inductance test frequency of 1 kHz. Frequency response characteristics beyond this specification are not provided and should be verified through API Delevan Inc. documentation or direct measurement for high-frequency applications.

Q: What is the tolerance range for these inductors? A: Both parts have an inductance tolerance of ±15%, meaning actual inductance values will fall within the range of 2.805 µH to 3.795 µH at 1 kHz test frequency.
