NJM360D Equivalent & Substitute Parts

Part Overview

The NJM360D is a single differential comparator integrated circuit manufactured by Nisshinbo Micro Devices Inc., housed in an 8-DIP through-hole package. This device features complementary TTL output and operates across a supply voltage range of 4.5V to 6.5V (±2.25V dual supply). The NJM360D is classified as an obsolete product, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility while meeting current component availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NJM360D requires evaluation of core functional parameters that define comparator operation and circuit compatibility. The primary substitution criteria are:

Functional Parameters:

• Comparator type (Differential)
• Output configuration (Complementary, TTL)
• Supply voltage compatibility
• Input offset voltage specification
• Input bias current specification
• Output current capability
• Operating temperature range

Physical Parameters:

• Package type and pin configuration
• Mounting technology (Through Hole)

The LM361H/NOPB and LM361M are identified as substitute parts based on their differential comparator architecture with complementary TTL output. Both devices maintain the core functional classification while offering active product status and improved availability compared to the obsolete NJM360D.

Parameter Comparison

Engineering Selection Recommendations

LM361H/NOPB (Texas Instruments): This device is classified as Active product status with ROHS3 compliance and REACH Unaffected designation. The LM361H/NOPB operates across a wider supply voltage range (±5V ~ 15V) compared to the NJM360D, providing greater flexibility in power supply configurations. The device features a dual-element comparator architecture within a TO-100-10 metal can package. Input offset voltage and input bias current specifications match the NJM360D at specified operating conditions. Propagation delay is specified at 20ns maximum. The operating temperature range (0°C ~ 70°C) is narrower than the NJM360D. This substitute is suitable for applications where the extended supply voltage range and active product status are prioritized, with consideration for package form factor differences.

LM361M (National Semiconductor): This device maintains Active product status and is classified as REACH Affected. The LM361M is identified as a high-speed differential comparator. Detailed electrical specifications beyond the base product classification are not provided in the available data. This substitute is suitable for applications where National Semiconductor sourcing is preferred and active product availability is required.

Frequently Asked Questions (FAQ)

Q: Why is the NJM360D classified as obsolete? A: The NJM360D is designated as an obsolete product by its manufacturer, Nisshinbo Micro Devices Inc. Obsolete classification indicates that the device is no longer in active production and future availability cannot be guaranteed. Substitute parts with active product status are recommended for new designs and ongoing production.

Q: Are the LM361H/NOPB and LM361M direct pin-for-pin replacements for the NJM360D? A: The LM361H/NOPB uses a TO-100-10 metal can package, while the NJM360D uses an 8-DIP package. These packages have different physical dimensions and pin configurations. The LM361M package type is not specified in the available data. Physical package compatibility must be verified before implementation.

Q: What are the key functional differences between the NJM360D and its substitutes? A: The NJM360D is a single-element comparator, while the LM361H/NOPB contains two differential comparator elements. The LM361H/NOPB operates across a wider supply voltage range (±5V ~ 15V) compared to the NJM360D (4.5V, ±2.25V ~ 6.5V). The LM361H/NOPB specifies a maximum propagation delay of 20ns. The operating temperature range of the LM361H/NOPB (0°C ~ 70°C) is narrower than the NJM360D (-40°C ~ 85°C).

Q: Can the LM361H/NOPB be used in applications requiring the full -40°C ~ 85°C temperature range of the NJM360D? A: The LM361H/NOPB is specified for operation only within 0°C ~ 70°C. Applications requiring operation below 0°C or above 70°C cannot use this substitute without additional thermal management or alternative component selection.

Q: What compliance certifications apply to the substitute parts? A: The LM361H/NOPB is ROHS3 Compliant and REACH Unaffected. The LM361M is classified as REACH Affected. Compliance requirements for your application must be verified against these designations.

Q: How do the input bias current specifications compare? A: The NJM360D specifies a maximum input bias current of 20µA. The LM361H/NOPB specifies 10µA @ 5V, representing lower input bias current at the specified operating voltage. Lower input bias current may reduce loading effects on signal sources in high-impedance applications.

Q: Are there inventory considerations for these substitute parts? A: The NJM360D has 6000 pieces in stock. The LM361H/NOPB has 1065 pieces in stock. The LM361M has 1470 pieces in stock. Inventory levels should be verified with your component supplier for current availability.
