HC68-1052SM Equivalent & Substitute Parts

Part Overview

The HC68-1052SM is a 10.5 µH shielded toroidal inductor manufactured by Gowanda Electronics, designed for surface mount applications requiring moderate inductance with high current handling capability. This component is classified as Active product status with 639 units currently in stock. Substitute parts are identified when equivalent electrical performance can be achieved within the allowable parameter tolerances for toroidal inductor applications, particularly when shielding requirements or specific inductance values permit alternative selection.

Substitute Part Grouping Explanation

Substitution eligibility for toroidal inductors is determined by the following criteria:

Inductance Compatibility: The substitute part must operate within the circuit's inductance tolerance window. The HC68-1052SM tolerance of ±20% establishes the acceptable inductance range (8.4 µH to 12.6 µH).
Current Rating: The substitute must support the required current without saturation. The HC68-1052SM requires minimum 13.2 A capability.
DC Resistance: Equivalent or lower DCR ensures comparable power dissipation characteristics. The HC68-1052SM specifies 6.2 mOhm maximum.
Mounting Configuration: Both parts must be surface mount compatible with compatible package footprints.
Operating Temperature Range: The substitute must cover the application's thermal requirements.
Shielding Characteristics: Shielding requirements depend on electromagnetic interference (EMI) sensitivity of the circuit.

The PE-53700NL is identified as a substitute candidate based on matching DC resistance (6.2 mOhm), superior current rating (15.4 A), compatible surface mount configuration, and overlapping operating temperature range. However, the PE-53700NL features unshielded construction and reduced inductance (5.2 µH), which may require circuit-level evaluation.

Mounting Type	Surface Mount	Surface Mount	Compatible mounting configuration
Package Type	Nonstandard	Nonstandard	Both use nonstandard packages; footprint compatibility required
RoHS Status	Not applicable	ROHS3 Compliant	Substitute meets ROHS3 compliance

Engineering Selection Recommendations

Selection between HC68-1052SM and PE-53700NL depends on specific application requirements:

HC68-1052SM is the primary choice when:

Shielded construction is required to minimize electromagnetic interference
Inductance value of 10.5 µH is specified in circuit design
Operating temperature minimum of -30°C is required
RoHS compliance status is not a constraint

PE-53700NL may be considered when:

Unshielded construction is acceptable for the application
Circuit design permits inductance value of 5.2 µH
Extended low-temperature operation to -40°C is beneficial
ROHS3 compliance is required
Higher current rating (15.4 A vs 13.2 A) provides additional margin

Both parts share identical DC resistance specifications (6.2 mOhm maximum) and compatible surface mount mounting types. Physical footprint verification is necessary due to nonstandard package classifications.

Frequently Asked Questions (FAQ)

Q: Can PE-53700NL directly replace HC68-1052SM in my circuit?

A: Direct replacement requires verification of two critical factors: (1) circuit tolerance of the reduced inductance value (5.2 µH vs 10.5 µH), and (2) acceptance of unshielded construction if the original design relied on shielding for EMI control. DC resistance and current rating are compatible.

Q: What is the inductance tolerance range for HC68-1052SM?

A: With ±20% tolerance applied to 10.5 µH, the acceptable inductance range is 8.4 µH to 12.6 µH. The PE-53700NL at 5.2 µH falls outside this range and requires circuit-level analysis.

Q: Are the physical packages compatible between these parts?

A: Both parts use nonstandard package classifications. Physical dimensions differ slightly (HC68-1052SM: 24.00mm × 23.88mm × 10.16mm height; PE-53700NL: 23.88mm × 23.88mm × 9.91mm height). Footprint compatibility must be verified against PCB layout requirements.

Q: What is the difference between shielded and unshielded toroidal inductors?

A: Shielded inductors (HC68-1052SM) contain electromagnetic shielding to reduce radiated EMI and susceptibility to external magnetic fields. Unshielded inductors (PE-53700NL) offer lower cost and smaller profile but may couple more readily with surrounding circuit elements. Selection depends on EMI requirements.

Q: Does PE-53700NL meet compliance requirements?

A: PE-53700NL is ROHS3 compliant. HC68-1052SM has RoHS status listed as "Not applicable." Compliance requirements should be verified against your specific regulatory framework.

Q: What is the current rating significance?

A: Current rating indicates the maximum continuous current the inductor can handle without saturation. PE-53700NL (15.4 A) exceeds HC68-1052SM (13.2 A) requirement, providing additional operational margin in high-current applications.
