Substitute Part Grouping Explanation

Substitute parts for the API Delevan 4426-1 are qualified based on the following criteria:

Primary Matching Parameters:

• Inductance value: 2.5 nH
• Core material: Air
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Physical dimensions: 0.145" L x 0.120" W (3.68mm x 3.05mm)
• Height - Seated (Max): 0.125" (3.18mm)

Secondary Compatibility Parameters:

• Current rating equal to or greater than 3 A
• Operating temperature range that encompasses or exceeds -55°C ~ 125°C
• Inductance frequency test at 150 MHz

The Würth Elektronik 744913025 meets all primary matching parameters and provides enhanced specifications in current rating (4 A versus 3 A) and inductance tolerance (±5% versus ±10%), making it functionally equivalent for direct substitution in the specified application.

Parameter Comparison

Engineering Selection Recommendations

Both the API Delevan 4426-1 and Würth Elektronik 744913025 are active production components with identical physical dimensions and inductance specifications. The Würth Elektronik 744913025 provides improved specifications including higher current rating (4 A), tighter inductance tolerance (±5%), and higher self-resonant frequency (12.5GHz). The Würth Elektronik part carries AEC-Q200 automotive qualification and ROHS3 compliance, whereas the API Delevan part is RoHS non-compliant. Selection between these parts depends on compliance requirements and operating temperature range constraints. The API Delevan 4426-1 supports extended low-temperature operation to -55°C, while the Würth Elektronik 744913025 operates from -40°C minimum.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744913025 directly replace the API Delevan 4426-1?

A: Yes. Both components share identical inductance (2.5 nH), core material (air), shielding (unshielded), mounting type (surface mount), and physical dimensions (0.145" L x 0.120" W, 3.68mm x 3.05mm height 0.125"). The Würth part provides equal or superior electrical performance with higher current rating and tighter tolerance.

Q: What are the key differences between these parts?

A: The Würth Elektronik 744913025 offers higher current rating (4 A versus 3 A), tighter inductance tolerance (±5% versus ±10%), higher self-resonant frequency (12.5GHz versus 3GHz), and includes AEC-Q200 and ROHS3 compliance. The API Delevan 4426-1 supports lower minimum operating temperature (-55°C versus -40°C).

Q: Are there packaging differences?

A: Both components are supplied in Tape & Reel (TR) packaging with identical physical dimensions and mounting footprint.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For applications requiring extended low-temperature operation below -40°C, the API Delevan 4426-1 is necessary. For applications where compliance certifications and improved electrical specifications are required, the Würth Elektronik 744913025 is preferred.

Q: Are there DC resistance specifications available?

A: The API Delevan 4426-1 does not specify DC resistance. The Würth Elektronik 744913025 specifies maximum DC resistance of 1.1mOhm.
