FPT705-230-R Equivalent & Substitute Parts

Part Overview

The FPT705-230-R is a 230 nH shielded drum core wirewound inductor manufactured by Vicor Corporation, designed for surface mount applications. This component delivers 13 A continuous current rating with a saturation current of 23 A and exhibits a DC resistance of 0.65 mOhm. The inductor operates across a temperature range of -55°C to 125°C and maintains ROHS3 compliance. The part is currently active in production with 5,725 units in stock. Identifying equivalent and substitute parts is necessary for supply chain continuity, design flexibility, and procurement optimization when the primary part number becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitute parts for the FPT705-230-R must satisfy the following critical parameters to ensure functional and mechanical compatibility:

Electrical Parameters (Mandatory Match):

• Inductance value of 230 nH with ±10% tolerance
• Continuous current rating of 13 A minimum
• Saturation current (Isat) of 23 A minimum
• DC resistance (DCR) of 0.65 mOhm maximum

Mechanical Parameters (Mandatory Match):

• Ferrite drum core construction with shielding
• Surface mount wirewound inductor type
• Nonstandard package (2727) with dimensions 7.20 mm × 7.00 mm × 5.35 mm (max height)

Environmental & Compliance Parameters (Mandatory Match):

• Operating temperature range of -55°C to 125°C minimum
• ROHS3 compliance
• Inductance test frequency of 1 MHz

Parts meeting all specified parameters within the stated tolerances are classified as direct parametric equivalents. The FPT705-230-R from Vicor Corporation's FLAT-PAC series represents the primary reference for this substitution analysis.

Engineering Selection Recommendations

The FPT705-230-R is an active production component from Vicor Corporation with confirmed ROHS3 compliance and REACH unaffected status. When selecting equivalent or substitute inductors, the following engineering criteria apply:

Compliance Verification: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements for the target application.

Product Status: Active production status ensures long-term availability and supply chain stability. Substitute parts should maintain active status to support ongoing procurement requirements.

Electrical Performance: Substitute inductors must deliver the specified 230 nH inductance within ±10% tolerance, support 13 A continuous current with 23 A saturation capability, and maintain 0.65 mOhm DC resistance. These parameters are non-negotiable for circuit performance and thermal management.

Mechanical Compatibility: The nonstandard 2727 package with 7.20 mm × 7.00 mm footprint and 5.35 mm maximum height is a critical constraint. Substitute parts must fit the existing PCB layout without modification.

Environmental Performance: The -55°C to 125°C operating temperature range must be maintained to ensure reliability across the full application temperature spectrum.

Frequently Asked Questions (FAQ)

Q: What makes a part a direct equivalent to the FPT705-230-R?

A: A direct equivalent must match all electrical parameters (230 nH inductance ±10%, 13 A continuous current, 23 A saturation current, 0.65 mOhm DCR), core material (ferrite), shielding type (shielded), mounting method (surface mount), package dimensions (7.20 mm × 7.00 mm × 5.35 mm max height), and operating temperature range (-55°C to 125°C). Compliance certifications (ROHS3, REACH unaffected) must also align.

Q: Can I substitute a different inductance value?

A: No. The 230 nH inductance value is a critical circuit parameter. Substitution with different inductance values will alter circuit performance, frequency response, and impedance characteristics. Only parts rated at 230 nH ±10% are acceptable substitutes.

Q: What if a substitute part has lower DC resistance?

A: Lower DC resistance is acceptable from a thermal and efficiency perspective, provided all other parameters remain within specification. However, the part must still meet the minimum 13 A continuous current rating and 23 A saturation current requirement.

Q: Are there package compatibility concerns?

A: Yes. The nonstandard 2727 package with specific dimensions (7.20 mm × 7.00 mm × 5.35 mm max height) is a hard constraint. Substitute parts must fit the existing PCB footprint without layout modifications. Standard package inductors are not compatible.

Q: Does the shielding requirement affect substitution options?

A: Yes. The FPT705-230-R is a shielded inductor. Unshielded alternatives will introduce electromagnetic interference into adjacent circuits and are not acceptable substitutes. Shielding must be maintained.

Q: What is the significance of the 1 MHz test frequency?

A: The inductance value of 230 nH is measured and specified at 1 MHz. Substitute parts must be characterized at the same frequency to ensure accurate inductance matching and circuit performance.

Q: Can I use a part with a higher current rating?

A: Yes. A substitute part with a higher continuous current rating (above 13 A) and higher saturation current (above 23 A) is acceptable, provided all other parameters match. Higher current ratings provide additional design margin without compromising performance.

Q: What compliance certifications are mandatory for substitution?

A: ROHS3 compliance and REACH unaffected status are mandatory. These certifications ensure regulatory compliance for the target application and market. Substitute parts lacking these certifications are not acceptable.
