HR01400J Equivalent & Substitute Parts

Part Overview

The HR01400J is a 40 Ohm ±5% 1/16W axial through-hole resistor manufactured by Kyocera AVX using thick film composition. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 125°C and is RoHS non-compliant with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HR01400J is determined by the following critical parameters:

• Resistance value: 40 Ohms (exact match required)
• Tolerance: ±5% (acceptable range for equivalent functionality)
• Package configuration: Axial through-hole (mechanical compatibility)
• Power rating: Minimum 0.063W (equal or greater capacity acceptable)
• Operating temperature range: Must encompass or exceed -55°C to 125°C

The ALSR0140R00JE12 qualifies as a functional equivalent based on matching resistance, tolerance, and axial package type. While the substitute exhibits different composition (wirewound vs. thick film) and superior power rating (1W vs. 1/16W), these differences do not prevent substitution when the application does not require the specific thermal or frequency characteristics of thick film construction.

Parameter Comparison

Engineering Selection Recommendations

The ALSR0140R00JE12 is the designated manufacturer-recommended substitute for the HR01400J. Selection of this equivalent part is supported by the following factors:

• Both components share identical resistance value (40 Ohms) and tolerance (±5%), ensuring electrical equivalence in circuit function
• Axial package configuration provides mechanical compatibility with existing PCB layouts and through-hole assembly processes
• The substitute's 1W power rating exceeds the original 1/16W specification, providing margin for thermal performance in the application
• ALSR0140R00JE12 maintains active product status with confirmed inventory availability, eliminating obsolescence risk
• ROHS3 compliance of the substitute aligns with current regulatory requirements, whereas the original part is RoHS non-compliant
• Extended operating temperature range (-65°C to 250°C) of the substitute encompasses the original specification (-55°C to 125°C)

Frequently Asked Questions (FAQ)

Q: Can the ALSR0140R00JE12 be used as a direct replacement for the HR01400J in existing designs?

A: Yes. Both components provide 40 Ohms ±5% resistance in axial package configuration. The substitute's higher power rating and extended temperature range do not prevent direct substitution in applications designed for the original part.

Q: What is the primary difference between the HR01400J and ALSR0140R00JE12?

A: The main differences are composition (thick film vs. wirewound), power rating (1/16W vs. 1W), and temperature coefficient (±250ppm/°C vs. ±30ppm/°C). The substitute offers superior thermal stability and power handling capacity.

Q: Does the larger physical size of the ALSR0140R00JE12 affect PCB compatibility?

A: The substitute is physically larger (0.110" diameter x 0.406" length vs. 0.036" square x 0.075" length). PCB layout verification is necessary to confirm clearance and spacing compatibility with existing through-hole positions.

Q: Is the ALSR0140R00JE12 suitable for high-frequency applications?

A: Wirewound resistors exhibit inductive characteristics that may affect performance at high frequencies. Applications requiring low inductance should evaluate frequency-dependent behavior before substitution.

Q: What is the inventory status of the substitute part?

A: The ALSR0140R00JE12 is active production with 1023 pieces confirmed in stock as new original inventory.
