Engineering Selection Recommendations

The LSDND5050PKT2R2MM is a direct electrical and mechanical equivalent to the MDPK5050T2R2MM. Both components are manufactured by Taiyo Yuden and share identical specifications across all critical parameters: inductance value, current rating, saturation current, DC resistance, shielding, core material, package footprint, height, and operating temperature range.

The primary distinction is product status: the MDPK5050T2R2MM is designated as not for new designs, while the LSDND5050PKT2R2MM is classified as active. This status difference indicates that the LSDND5050PKT2R2MM represents the current production alternative and is the appropriate selection for new applications requiring a 2.2 µH shielded metal core wirewound inductor with 3.6 A current rating and 55 mOhm maximum DC resistance.

Both parts maintain full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment for applications subject to these standards. The identical MSL rating of 1 (Unlimited) indicates equivalent moisture handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the LSDND5050PKT2R2MM be used as a direct replacement for the MDPK5050T2R2MM in existing designs?

A: Yes. The LSDND5050PKT2R2MM meets all electrical and mechanical specifications of the MDPK5050T2R2MM. Both components have identical inductance (2.2 µH), current rating (3.6 A), saturation current (4.1 A), DC resistance (55 mOhm maximum), shielding, core material, package footprint (4.90mm x 4.90mm), and operating temperature range (-40°C to 125°C). No circuit modifications are required.

Q: What is the difference between the MDPK5050T2R2MM and LSDND5050PKT2R2MM?

A: The components are electrically and mechanically identical. The primary difference is product status: MDPK5050T2R2MM is not for new designs, while LSDND5050PKT2R2MM is active. Both are manufactured by Taiyo Yuden and belong to different product series (MD and LSDN respectively).

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

A: No. Both components are ROHS3 compliant, REACH unaffected, and have identical MSL ratings of 1 (Unlimited). They share the same operating temperature range of -40°C to 125°C and identical moisture sensitivity specifications.

Q: Does the package footprint remain the same for both parts?

A: Yes. Both the MDPK5050T2R2MM and LSDND5050PKT2R2MM have identical package dimensions of 0.193" L x 0.193" W (4.90mm x 4.90mm) with a maximum seated height of 0.055" (1.40mm). No PCB layout modifications are necessary.

Q: Why is the MDPK5050T2R2MM marked as not for new designs?

A: The "not for new designs" designation indicates that the MDPK5050T2R2MM is a legacy product. The LSDND5050PKT2R2MM, classified as active, is the current production equivalent and should be used for new applications.
