Hammond Manufacturing 1535G Equivalent & Substitute Parts

Part Overview

The Hammond Manufacturing 1535G is a 10 mH fixed unshielded wirewound inductor rated for 100 mA with a maximum DC resistance of 31 Ohm, designed for through-hole axial mounting. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The 1535G operates at a self-resonant frequency of 710 kHz with a Q factor of 108 at 79 kHz, suitable for general-purpose filtering and energy storage applications in electronic circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1535G is determined by the following critical parameters: inductance value (10 mH), inductance tolerance (±5%), current rating capability (minimum 100 mA), DC resistance (maximum 31 Ohm), unshielded configuration, through-hole axial mounting, and wirewound construction type. Parts meeting these electrical and mechanical specifications are classified as direct or similar substitutes based on their adherence to these core requirements and their product status.

The two identified substitute parts meet the primary electrical specifications with acceptable variations in current rating and DC resistance within engineering tolerances:

• B82145A1106J000 (EPCOS - TDK Electronics): Direct substitute with active product status, higher current rating (110 mA), and slightly elevated DC resistance (35 Ohm Max)
• AIAP-02-103K (Abracon LLC): Similar substitute with active product status, higher current rating (140 mA), lower DC resistance (26.4 Ohm Max), and relaxed inductance tolerance (±10%)

Parameter Comparison

Engineering Selection Recommendations

B82145A1106J000 (EPCOS - TDK Electronics) is the primary direct substitute for the 1535G. This part maintains the same 10 mH inductance with ±5% tolerance and exceeds the current rating requirement at 110 mA. The DC resistance of 35 Ohm Max represents a 13% increase over the original specification but remains within acceptable engineering margins for most applications. The part carries active product status with ROHS3 compliance and established supply chain availability (3566 pcs in stock). The ferrite drum core construction provides improved thermal stability across the operating temperature range of -55°C to 125°C.

AIAP-02-103K (Abracon LLC) serves as an alternative substitute with superior electrical performance characteristics. This part delivers 140 mA current rating capability and the lowest DC resistance at 26.4 Ohm Max, providing reduced power dissipation. The inductance tolerance is relaxed to ±10%, which may require circuit validation in precision applications. The part is active with ROHS3 compliance and strong inventory availability (5151 pcs in stock). Operating temperature range is -40°C to 85°C, which is narrower than the EPCOS alternative.

Selection between these substitutes depends on circuit requirements for current headroom, DC resistance constraints, and operating temperature range. Both parts are ROHS3 compliant and actively manufactured, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the B82145A1106J000 directly replace the 1535G in all applications?

A: The B82145A1106J000 meets the core electrical specifications of the 1535G with equivalent inductance and tolerance. The 4 Ohm increase in DC resistance (35 Ohm vs. 31 Ohm) results in approximately 13% higher power dissipation at rated current. Circuit validation is required for applications with strict power budget constraints or thermal limitations.

Q: What is the difference between the EPCOS and Abracon substitutes?

A: The EPCOS B82145A1106J000 maintains the original ±5% inductance tolerance and provides a wider operating temperature range (-55°C to 125°C). The Abracon AIAP-02-103K offers lower DC resistance (26.4 Ohm) and higher current rating (140 mA) but has relaxed inductance tolerance (±10%) and narrower operating temperature range (-40°C to 85°C). The EPCOS part is the closer electrical match; the Abracon part offers superior current handling and lower losses.

Q: Are both substitute parts RoHS compliant?

A: Yes, both B82145A1106J000 and AIAP-02-103K are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Does the axial package remain the same across all three parts?

A: All three parts use through-hole axial mounting with the same package classification. Physical dimensions vary: the 1535G measures 0.531" Dia x 0.875" L, the EPCOS part measures 0.256" Dia x 0.472" L, and the Abracon part measures 0.252" Dia x 0.551" L. PCB layout and mechanical clearance must be verified during substitution.

Q: Which substitute part should be selected for new designs?

A: For new designs, either active substitute part is acceptable. The EPCOS B82145A1106J000 is recommended for applications requiring the original ±5% inductance tolerance and extended temperature range. The Abracon AIAP-02-103K is recommended for applications prioritizing low DC resistance and high current margin. Both parts offer established supply chains and long-term availability.
