Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Inductance value: 18.5 nH ±5% tolerance
• Core material: Air
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Physical package dimensions: 3.68mm × 3.05mm × 3.18mm
• Q factor @ 150 MHz: 132
• Inductance test frequency: 150 MHz

Secondary Compatibility Parameters:

• Current rating: minimum 3 A
• Operating temperature range: must encompass -55°C to 125°C or be compatible with application requirements
• Packaging format: Tape & Reel

Substitute parts are classified into two categories:

Direct Manufacturer Substitutes: Parts from the same manufacturer (API Delevan) with identical electrical specifications and equivalent mechanical form factor.

Similar Manufacturer Substitutes: Parts from alternative manufacturers meeting all primary equivalence criteria with potential enhancements in secondary parameters such as current rating, DC resistance specification, or compliance certifications.

Engineering Selection Recommendations

For Direct Substitution (API Delevan 4426R-5):

The 4426R-5 maintains identical electrical and mechanical specifications to the 4426-5 while providing ROHS3 compliance. This part is suitable for applications requiring regulatory compliance upgrades without performance modification. Both parts share the same series lineage and manufacturing standards from API Delevan Inc.

For Enhanced Performance Substitution (Würth Elektronik 744913118):

The 744913118 provides equivalent inductance and Q factor performance with the following enhancements:

• Current rating increased to 4 A (33% margin above 3 A requirement)
• DC resistance specified at 3.9 mOhm maximum (quantified performance metric)
• ROHS3 compliance certification
• AEC-Q200 automotive qualification rating

The 744913118 is suitable for applications requiring higher current headroom, specified DC resistance performance, or automotive-grade reliability standards. The reduced self-resonant frequency (2.5 GHz versus 3 GHz) and narrower operating temperature lower bound (-40°C versus -55°C) must be evaluated against specific application requirements.

Compliance Considerations:

The 4426-5 is RoHS non-compliant. Both substitute parts (4426R-5 and 744913118) are ROHS3 compliant, supporting regulatory requirements in restricted substance directives.

Frequently Asked Questions (FAQ)

Q: Can the 4426R-5 be used as a direct replacement for the 4426-5?

A: Yes. The 4426R-5 is electrically and mechanically identical to the 4426-5 across all critical parameters: 18.5 nH inductance, ±5% tolerance, 3 A current rating, 132 Q factor at 150 MHz, and identical physical dimensions. The primary difference is ROHS3 compliance status.

Q: What are the key differences between the 4426-5 and the Würth Elektronik 744913118?

A: Both parts maintain 18.5 nH inductance and 132 Q factor at 150 MHz with identical physical dimensions. The 744913118 provides 4 A current rating (versus 3 A), specified 3.9 mOhm maximum DC resistance, AEC-Q200 automotive qualification, and ROHS3 compliance. The 744913118 has a 2.5 GHz self-resonant frequency compared to 3 GHz for the 4426-5, and a lower operating temperature minimum of -40°C versus -55°C.

Q: Is the 744913118 suitable for applications requiring -55°C operation?

A: No. The 744913118 operating temperature range is -40°C to 125°C. Applications requiring -55°C minimum operation must use the 4426-5 or 4426R-5, which are rated to -55°C to 125°C.

Q: Does the reduced self-resonant frequency of the 744913118 affect substitution eligibility?

A: The self-resonant frequency difference (2.5 GHz versus 3 GHz) must be evaluated within specific application frequency requirements. At the specified test frequency of 150 MHz, both parts deliver equivalent Q factor performance (132). Applications operating near or above 2.5 GHz require detailed frequency response analysis.

Q: Are all three parts available in Tape & Reel packaging?

A: Yes. The 4426-5, 4426R-5, and 744913118 are all supplied in Tape & Reel packaging format suitable for automated assembly processes.

Q: What is the significance of AEC-Q200 rating on the 744913118?

A: AEC-Q200 is an automotive electronics qualification standard. The 744913118 meets automotive-grade reliability and performance standards. The 4426-5 and 4426R-5 do not carry this certification and are suitable for general industrial and commercial applications.

Q: Can the 4 A current rating of the 744913118 be used in a 3 A application?

A: Yes. The 744913118 with 4 A rating is suitable for applications requiring 3 A or less, providing additional current margin and thermal headroom.
