Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4426-3NC is determined by strict equivalence in the following critical parameters:

• Inductance value: 8 nH (exact match required)
• Wirewound construction type with air core material
• Unshielded configuration
• Surface mount nonstandard package with identical physical dimensions (0.145" L x 0.120" W, 3.18mm max height)
• Tape & Reel packaging format

The AL12A08N0GTR from KYOCERA AVX meets these core substitution criteria. While the substitute part exhibits improved specifications in certain areas (higher current rating, lower DCR, tighter tolerance, higher self-resonant frequency), these enhancements do not preclude substitution when the 4426-3NC is specified, as they represent superior or equivalent performance within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

The AL12A08N0GTR serves as a direct functional equivalent to the 4426-3NC for applications requiring 8 nH inductance in surface mount nonstandard packages. Selection between these parts should be based on the following criteria:

4426-3NC (API Delevan): Select when the original design specification explicitly requires this part number or when the extended lower operating temperature limit of -55°C is required for the application.

AL12A08N0GTR (KYOCERA AVX): Select when RoHS3 compliance is a regulatory or procurement requirement, or when the improved specifications (tighter inductance tolerance of ±2%, higher current rating of 4 A, specified DCR of 2.6mOhm max, and higher self-resonant frequency of 5GHz) provide performance advantages for the intended circuit application. The operating temperature range of -40°C ~ 125°C is suitable for standard commercial and industrial applications.

Both parts maintain identical physical dimensions, identical Q factor at 150 MHz, and identical moisture sensitivity classification, ensuring mechanical and thermal compatibility in surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can AL12A08N0GTR replace 4426-3NC in existing designs?

A: Yes, the AL12A08N0GTR is electrically and mechanically compatible as a substitute. Both parts share identical inductance values (8 nH), core material (air), shielding configuration (unshielded), physical dimensions (0.145" L x 0.120" W, 3.18mm max height), and Q factor (140 @ 150MHz). The substitute part offers improved specifications including tighter tolerance (±2% vs ±5%), higher current rating (4 A vs 3 A), and higher self-resonant frequency (5GHz vs 3GHz).

Q: What are the key differences between these parts?

A: The primary differences are: inductance tolerance (±2% vs ±5%), current rating (4 A vs 3 A), DC resistance specification (2.6mOhm max vs not specified), self-resonant frequency (5GHz vs 3GHz), operating temperature range (-40°C ~ 125°C vs -55°C ~ 125°C), and RoHS compliance status (ROHS3 Compliant vs RoHS non-compliant).

Q: Are the physical packages identical?

A: Yes. Both parts use identical nonstandard surface mount packages with dimensions of 0.145" L x 0.120" W (3.68mm x 3.05mm) and maximum seated height of 0.125" (3.18mm). Both are supplied in Tape & Reel packaging format.

Q: Which part should be selected for low-temperature applications?

A: The 4426-3NC supports operation down to -55°C, while the AL12A08N0GTR operates from -40°C. For applications requiring temperatures below -40°C, the 4426-3NC is the appropriate selection.

Q: Is RoHS compliance a factor in substitution?

A: The AL12A08N0GTR is ROHS3 compliant, while the 4426-3NC is RoHS non-compliant. If regulatory or procurement requirements mandate RoHS compliance, the AL12A08N0GTR is the required selection.

Q: Do both parts have the same moisture sensitivity?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
