Würth Elektronik 744052007 Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 744052007 is a 7.5 µH shielded drum core wirewound inductor rated for 1.35 A continuous current with a maximum DC resistance of 90mOhm. This surface mount component operates across the temperature range of -40°C to 125°C and is housed in a 2323 (5858 Metric) package. The part is Active status and ROHS3 compliant, making it suitable for modern electronic applications requiring compact, shielded inductance solutions. Equivalent parts may be required due to inventory constraints, design optimization, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution of the Würth Elektronik 744052007 is determined by the following critical parameters:

Primary Substitution Criteria:

• Inductance value within tolerance range (7.5 µH ±30% = 5.25 µH to 9.75 µH)
• Current rating equal to or greater than 1.35 A
• DC resistance at or below 90mOhm
• Shielded construction
• Surface mount configuration
• Operating temperature range covering -40°C to 125°C minimum
• ROHS3 compliance and MSL rating of 1

The Pulse Electronics PG0087.682NL meets these substitution criteria with a 6.8 µH inductance (within the ±30% tolerance band), 1.5 A current rating, 105mOhm DC resistance, shielded design, and extended operating temperature to 130°C.

Parameter Comparison

Engineering Selection Recommendations

The Pulse Electronics PG0087.682NL is a qualified substitute for the Würth Elektronik 744052007 based on the following engineering criteria:

Compliance & Certification: Both parts maintain ROHS3 compliance and MSL rating of 1, ensuring compatibility with modern manufacturing and environmental standards.

Electrical Performance: The substitute part delivers 1.5 A current rating, exceeding the primary part's 1.35 A requirement. The 6.8 µH inductance falls within the ±30% tolerance specification of the primary part (acceptable range: 5.25 µH to 9.75 µH). The 105mOhm DC resistance is slightly elevated compared to the 90mOhm maximum of the primary part but remains within acceptable operational parameters for most applications.

Thermal Performance: The extended operating temperature range of -40°C to 130°C provides additional thermal margin beyond the primary part's -40°C to 125°C specification.

Physical Compatibility: Both parts are surface mount components with MSL 1 rating. Package dimensions differ slightly (primary: 5.80mm x 5.80mm; substitute: 6.20mm x 6.20mm), requiring PCB layout verification for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the Pulse Electronics PG0087.682NL directly replace the Würth Elektronik 744052007 in my circuit?

A: The substitute part meets the core electrical requirements (inductance within tolerance, equal or higher current rating, shielded construction, surface mount). However, the slightly larger package footprint (6.20mm vs 5.80mm) requires PCB layout verification. The marginally higher DC resistance (105mOhm vs 90mOhm) may introduce minor thermal differences in high-current applications.

Q: What is the inductance tolerance range for substitution?

A: The primary part specifies ±30% tolerance on 7.5 µH, establishing an acceptable range of 5.25 µH to 9.75 µH. The substitute part's 6.8 µH inductance falls within this range.

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

A: Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited). No compliance differences exist between the primary and substitute parts.

Q: How does the package size difference affect PCB design?

A: The primary part uses a 2323 (5858 Metric) package measuring 5.80mm x 5.80mm. The substitute part uses a nonstandard package measuring 6.20mm x 6.20mm. Both maintain the same 2.00mm seated height. PCB footprint and routing must be evaluated for space-constrained layouts.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The substitute part's 105mOhm DC resistance compared to the primary part's 90mOhm maximum represents a 16.7% increase. In applications operating near the 1.35 A rating, this results in proportionally higher resistive losses and heat generation. For applications operating below 1.0 A, this difference is typically negligible.
