Key Parameters

Substitute Part Grouping Explanation

The Würth Elektronik 744851101 is identified as a functional substitute based on the following substitution criteria:

Coil Configuration: Both components feature 2-coil inductor arrays, enabling equivalent dual-inductance functionality.

Series Inductance Compatibility: The 744851101 provides 40 µH series inductance, which encompasses the 18.75 µH requirement of the 7007 through parallel connection configuration (10 µH parallel inductance available).

Current Handling: The 744851101 delivers 5.3 A parallel current rating, meeting or exceeding the 5 A series requirement of the 7007.

DC Resistance: The 744851101 specifies 22 mOhm maximum parallel DCR, comparable to the 7007's 20 mOhm maximum series DCR.

Operating Temperature Range: The 744851101 operates -40°C to 125°C, covering the 7007's -55°C to 105°C range within the upper boundary.

Mounting Transition: The 744851101 is surface-mount technology (SMD), representing a design modernization from the 7007's through-hole configuration.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The Bourns 7007 is classified as obsolete. The Würth Elektronik 744851101 maintains active product status with current manufacturing availability, supporting long-term supply chain continuity.

Compliance Status: The 744851101 is ROHS3 compliant, whereas the 7007 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must transition to the 744851101 or equivalent compliant alternatives.

Certification Alignment: Both components carry REACH Unaffected status and EAR99 ECCN classification, maintaining equivalent regulatory positioning for export and material compliance.

Moisture Sensitivity: Both components specify MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744851101 directly replace the Bourns 7007 in existing through-hole designs?

A: Direct mechanical replacement is not possible. The 744851101 is surface-mount technology, while the 7007 is through-hole mounted. PCB redesign is required to accommodate the different mounting footprint and lead configuration.

Q: What inductance value should be used when substituting with the 744851101?

A: The 744851101 provides 10 µH in parallel configuration and 40 µH in series configuration. Circuit design must accommodate these available inductance values rather than the 7007's 18.75 µH series specification.

Q: Are there temperature range limitations when using the 744851101 as a substitute?

A: The 744851101 operates -40°C to 125°C. Applications requiring the 7007's lower temperature limit of -55°C cannot use the 744851101 without thermal performance verification.

Q: Does the shielding difference between the 7007 and 744851101 affect substitution suitability?

A: The 7007 is unshielded while the 744851101 is shielded. Shielding provides electromagnetic interference mitigation. Circuit performance must be evaluated to determine if the shielding change impacts system operation.

Q: What is the current rating consideration when substituting these components?

A: The 7007 provides 5 A series current rating. The 744851101 provides 5.3 A parallel current rating. Circuit configuration must align with the available current ratings of the selected connection mode.
