PTHF10R-59H Equivalent & Substitute Parts

Part Overview

The PTHF10R-59H is a 10 µH shielded toroidal inductor manufactured by API Delevan Inc. in the PTHFR series. This component features a molybdenum permalloy core with a current rating of 14.5 A and a maximum DC resistance of 8 mOhm, optimized for through-hole radial horizontal mounting. The part is active in production and ROHS3 compliant. Equivalent and substitute parts become necessary when the primary component experiences supply constraints, inventory limitations, or when design requirements permit consideration of alternative core materials and shielding configurations that maintain electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the PTHF10R-59H is determined by the following critical electrical and mechanical parameters: inductance value (10 µH), current rating capacity (minimum 14.5 A), through-hole mounting capability, and toroidal form factor. The substitute part CTX10-10-52-R manufactured by Eaton - Electronics Division meets the primary electrical requirement of 10 µH inductance and exceeds the current rating at 16.9 A. Both parts are ROHS3 compliant and share the EAR99 ECCN classification. Primary differences include core material composition (Iron Powder versus Molybdenum Permalloy), DC resistance characteristics (5.1 mOhm Max versus 8 mOhm Max), tolerance band (±20% versus ±10%), and shielding configuration (Unshielded versus Shielded). Package orientation differs with CTX10-10-52-R specified for radial vertical mounting compared to the horizontal orientation of PTHF10R-59H.

Parameter Comparison

Engineering Selection Recommendations

Both PTHF10R-59H and CTX10-10-52-R are active production components with ROHS3 compliance and EAR99 ECCN classification. The CTX10-10-52-R provides superior current capacity margin with 16.9 A rating versus 14.5 A and lower DC resistance at 5.1 mOhm Max. Selection between these inductors must account for application-specific requirements regarding shielding necessity, tolerance specification (±10% versus ±20%), and PCB layout constraints imposed by the horizontal versus vertical mounting orientation difference. The PTHF10R-59H maintains shielded configuration benefits for noise-sensitive applications, while CTX10-10-52-R offers improved thermal performance through lower resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can CTX10-10-52-R directly replace PTHF10R-59H on existing circuit boards? A: Direct mechanical replacement requires PCB layout verification due to mounting orientation differences. PTHF10R-59H specifies radial horizontal mounting while CTX10-10-52-R specifies radial vertical mounting. Lead spacing and component height must be evaluated for compatibility.

Q: How does the shielding difference affect circuit performance? A: PTHF10R-59H shielded configuration provides EMI containment appropriate for sensitive signal applications. CTX10-10-52-R unshielded design may introduce coupling effects in noise-critical circuits. Application electromagnetic environment determines whether shielding is functionally required.

Q: What tolerance considerations apply when substituting these components? A: PTHF10R-59H specifies ±10% inductance tolerance while CTX10-10-52-R permits ±20%. Applications requiring tighter inductance control must verify CTX10-10-52-R tolerance band remains acceptable for circuit function.

Q: Does CTX10-10-52-R lower DC resistance provide operational benefits? A: Lower DC resistance at 5.1 mOhm Max versus 8 mOhm Max reduces resistive losses and heat generation. This characteristic benefits high-current applications and improves overall power efficiency.

Q: Are both parts suitable for identical operating temperature ranges? A: PTHF10R-59H operating temperature range is not specified in provided data. CTX10-10-52-R operates within -40°C to 75°C. Thermal compatibility must be verified for the specific application environment.
