Key Parameters

Substitute Part Grouping Explanation

Substitution of the FPT1006-340-R is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 340 nH with ±10% tolerance
• Current rating: 19 A minimum continuous current capability
• Saturation current: 40.5 A minimum
• DC resistance: 1 mOhm maximum

Mechanical Parameters:

• Core type: Ferrite drum core, wirewound construction
• Shielding: Shielded configuration required
• Mounting: Surface mount technology
• Package dimensions: 0.380" L x 0.335" W x 0.252" H maximum (9.65 mm x 8.50 mm x 6.40 mm)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 125°C
• RoHS3 compliance required
• REACH unaffected status

Substitute parts must match all electrical specifications, maintain identical mechanical form factor and mounting compatibility, and satisfy all regulatory compliance requirements. The nonstandard package classification indicates that dimensional precision is critical for PCB layout and thermal management.

Parameter Comparison

Engineering Selection Recommendations

The FPT1006-340-R is classified as obsolete. Direct equivalent substitution is limited to parts maintaining identical electrical specifications, mechanical form factor, and regulatory compliance status. The part satisfies ROHS3 compliance and REACH unaffected requirements, which must be maintained in any substitute selection.

The nonstandard package classification requires that substitute components maintain exact dimensional compatibility with the original PCB layout. The 0.380" x 0.335" x 0.252" maximum envelope is a critical constraint for thermal management and electromagnetic shielding effectiveness in high-current applications.

Current rating of 19 A and saturation current of 40.5 A establish the minimum performance threshold for substitute selection. DC resistance specification of 1 mOhm maximum is essential for minimizing power dissipation in power conversion and distribution circuits.

The ferrite drum core construction with shielding is specified for electromagnetic compatibility and thermal performance. Substitute parts must employ identical core material and shielding architecture to maintain circuit performance characteristics.

Frequently Asked Questions (FAQ)

Q: What makes the FPT1006-340-R obsolete, and why is substitution necessary?

A: The FPT1006-340-R is classified as obsolete by the manufacturer. Substitution becomes necessary for design continuity, production support, and long-term component availability. Equivalent parts must satisfy all electrical and mechanical specifications to ensure circuit performance and reliability.

Q: What are the critical parameters that determine if a substitute inductor is compatible?

A: Compatibility is determined by exact equivalence across inductance value (340 nH ±10%), current rating (19 A minimum), saturation current (40.5 A minimum), DC resistance (1 mOhm maximum), core material (ferrite), shielding configuration, and physical dimensions (0.380" x 0.335" x 0.252" maximum). Operating temperature range (-55°C to 125°C) and regulatory compliance (ROHS3, REACH unaffected) must also be maintained.

Q: Can inductors with different package types substitute for the FPT1006-340-R?

A: No. The nonstandard package classification indicates that the specific form factor is integral to circuit design. Substitute components must maintain identical surface mount dimensions and height specifications to ensure PCB layout compatibility and thermal management effectiveness.

Q: What is the significance of the 1 mOhm maximum DC resistance specification?

A: DC resistance directly impacts power dissipation and thermal performance in high-current applications. The 1 mOhm maximum specification ensures that resistive losses remain within design parameters. Substitute inductors must not exceed this resistance value.

Q: Why is ferrite core material specified, and can alternative core materials be used?

A: Ferrite core material is specified for its electromagnetic properties, thermal characteristics, and saturation performance at the 19 A operating current. The ferrite drum core construction with shielding provides the required inductance stability and electromagnetic containment. Alternative core materials are not acceptable substitutes.

Q: How does the saturation current specification of 40.5 A relate to the 19 A current rating?

A: The 19 A current rating is the continuous operating current specification. The saturation current of 40.5 A represents the current level at which the inductor's inductance value begins to degrade significantly. This margin ensures stable performance under normal operating conditions and transient current events.

Q: Are there any compliance considerations when selecting a substitute?

A: Yes. The substitute must maintain ROHS3 compliance and REACH unaffected status. These regulatory requirements ensure environmental and health safety standards are met. Any substitute part must provide documentation confirming equivalent compliance status.

Q: What role does the 100 kHz inductance test frequency play in substitution?

A: The 100 kHz test frequency is the standard measurement condition at which the 340 nH inductance value is specified and verified. Substitute inductors must be characterized at the same frequency to ensure accurate inductance value comparison and circuit performance prediction.
