Substitute Part Grouping Explanation

Substitute parts for the FPT705-200-R must satisfy the following critical parameters to ensure functional equivalence:

Inductance Value: 200 nH with ±10% tolerance Current Rating: Minimum 13 A continuous current capability Saturation Current: Minimum 25 A DC Resistance: 0.65 mOhm maximum Core Material: Ferrite construction Shielding: Shielded configuration required Mounting: Surface mount technology Package Dimensions: 7.20 mm L × 7.00 mm W × 5.35 mm H (maximum seated height) Operating Temperature: -55°C to 125°C range Compliance: ROHS3 compliant

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The FPT705-200-R series designation indicates membership in Vicor's FLAT-PAC inductor family, which maintains consistent electrical and mechanical specifications across the product line.

Parameter Comparison

Engineering Selection Recommendations

The FPT705-200-R is the primary part number for this inductor specification. Both the main part and its substitute maintain identical electrical and mechanical characteristics, ensuring direct interchangeability without circuit redesign or board layout modification.

Product Status Consideration: The Active status of both parts confirms ongoing manufacturer support and availability through authorized distribution channels.

Compliance Verification: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for commercial and industrial applications across global markets.

Supply Chain Application: When the FPT705-200-R becomes unavailable through primary sources, the substitute FPT705-200-R part number provides equivalent functionality. Procurement should verify current inventory status and lead times through authorized Vicor distributors.

Thermal and Electrical Performance: The -55°C to 125°C operating temperature range and 13 A continuous current rating with 25 A saturation capability remain consistent across all equivalent parts, ensuring reliable performance in target applications.

Frequently Asked Questions (FAQ)

Q: Can the FPT705-200-R be substituted with other inductors from different manufacturers?

A: Direct substitution requires matching all critical parameters: 200 nH inductance (±10% tolerance), 13 A current rating, 25 A saturation current, 0.65 mOhm DCR, ferrite drum core construction, shielded configuration, surface mount package, and 7.20 mm × 7.00 mm × 5.35 mm dimensions. Only parts meeting these specifications are functionally equivalent.

Q: What is the significance of the ±10% inductance tolerance?

A: The ±10% tolerance defines the acceptable inductance range as 180 nH to 220 nH. Substitute parts must maintain this tolerance specification to ensure circuit performance within design parameters.

Q: Are there any package compatibility concerns when substituting the FPT705-200-R?

A: The FPT705-200-R uses a nonstandard surface mount package with specific dimensions of 7.20 mm length, 7.00 mm width, and 5.35 mm maximum seated height. Substitute parts must match these exact dimensions to ensure PCB footprint compatibility without requiring board redesign.

Q: How does the 0.65 mOhm DC resistance affect component selection?

A: The DC resistance directly impacts power dissipation and thermal performance. Substitute parts must maintain 0.65 mOhm DCR to preserve thermal characteristics and prevent excessive heat generation in high-current applications.

Q: What is the difference between the 13 A current rating and 25 A saturation current?

A: The 13 A rating represents continuous operating current under specified thermal conditions. The 25 A saturation current indicates the maximum current before the inductor core saturates and inductance degrades. Substitute parts must meet or exceed both specifications.

Q: Does the shielded configuration affect substitution criteria?

A: Yes. The shielded drum core design reduces electromagnetic interference and crosstalk. Substitute parts must maintain shielded construction to preserve EMI performance and prevent circuit interference.

Q: Is the ROHS3 compliance status important for part substitution?

A: ROHS3 compliance is mandatory for applications subject to European Union regulations and similar global standards. Both the main part and substitutes must maintain ROHS3 compliance to satisfy procurement and regulatory requirements.

Q: Can the FPT705-200-R operate reliably at the temperature extremes of -55°C and 125°C?

A: Yes. The operating temperature range of -55°C to 125°C is specified for both the main part and substitutes. Substitute parts must maintain this full temperature range to ensure reliable operation across all environmental conditions.
