Key Parameters

Substitute Part Grouping Explanation

Substitution of the NJM2360D is determined by strict alignment of the following critical parameters:

Core Electrical Parameters:

• Function: Step-Up, Step-Down capability
• Topology: Buck, Boost configuration
• Output Configuration: Positive or Negative adjustable
• Number of Outputs: Single output
• Current - Output: 1.5A (Switch)
• Package / Case: 8-DIP (0.300", 7.62mm)

Voltage Compatibility Range:

• Input voltage range must encompass or match the NJM2360D range (2.5V to 40V minimum input)
• Output voltage adjustability must support 1.25V minimum and 40V maximum

Operational Constraints:

• Switching frequency range: 100Hz ~ 100kHz
• Operating temperature: -40°C ~ 85°C preferred for full compatibility
• Mounting type: Through Hole (8-DIP package)

Substitute parts are grouped into two categories: Direct Equivalents (matching all critical parameters) and Similar Parts (meeting core functional requirements with minor parameter variations).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

MC34063ABN and MC34063ECN are recommended as primary substitutes. Both are manufactured by STMicroelectronics with Active product status, ensuring long-term availability and supply chain stability. MC34063ABN operates across the full temperature range (-40°C ~ 85°C), matching the NJM2360D specification. MC34063ECN provides equivalent electrical performance with ROHS3 compliance and 1 (Unlimited) MSL rating.

MC34063AP1G, manufactured by onsemi, is an Active product offering ROHS3 compliance and equivalent output voltage range (1.25V to 40V). This part is suitable for applications where the 0°C ~ 70°C operating temperature range is acceptable.

Secondary Substitutes (Obsolete Product Status):

MC33063AP and MC34063AP are obsolete onsemi products with electrical characteristics closely matching the NJM2360D. These parts remain available in inventory but lack active manufacturer support. MC33063AP provides a direct functional equivalent with 100kHz fixed switching frequency. MC34063AP supports the full 100Hz ~ 100kHz switching frequency range, matching the NJM2360D specification.

Compatibility Considerations:

All substitute parts maintain the 8-DIP (0.300", 7.62mm) through-hole package, ensuring direct mechanical compatibility. Input voltage range differences (3V minimum vs. 2.5V minimum for NJM2360D) require circuit verification for applications operating below 3V input. Output voltage maximum variations (38V vs. 40V for STMicroelectronics parts) must be evaluated for designs requiring full 40V output capability.

Frequently Asked Questions (FAQ)

Q: Can MC34063ABN directly replace NJM2360D in all applications?

A: MC34063ABN provides functional equivalence across all critical parameters: Buck/Boost topology, 1.5A output current, 8-DIP package, and -40°C ~ 85°C operating temperature. However, verify that your circuit design does not depend on the NJM2360D's 2.5V minimum input voltage specification, as MC34063ABN requires 3V minimum input.

Q: What is the difference between MC34063AP1G and MC34063AP?

A: MC34063AP1G is an Active product with ROHS3 compliance and Not Applicable MSL rating, while MC34063AP is Obsolete with 1 (Unlimited) MSL. Both support 1.25V minimum output voltage and 40V maximum output voltage. MC34063AP1G operates at 100kHz fixed switching frequency, while MC34063AP supports 100Hz ~ 100kHz range. Operating temperature range differs: MC34063AP1G operates 0°C ~ 70°C, MC34063AP operates 0°C ~ 70°C.

Q: Is KA34063A suitable for low-temperature applications?

A: KA34063A operates within 0°C ~ 70°C temperature range, which is narrower than the NJM2360D specification of -40°C ~ 85°C. This part is not suitable for applications requiring operation below 0°C or above 70°C.

Q: Why do some substitutes specify 38V maximum output while NJM2360D specifies 40V?

A: MC34063ABN and MC34063ECN, both manufactured by STMicroelectronics, specify 38V maximum output voltage. Applications requiring output voltages between 38V and 40V must use alternative substitutes such as MC34063AP1G, MC34063AP, or MC33063AP, which support 40V maximum output.

Q: Are all substitute parts RoHS compliant?

A: RoHS compliance varies among substitutes. MC34063ABN, MC34063AP1G, and MC34063ECN are ROHS3 Compliant. KA34063A is ROHS3 Compliant. MC33063AP and MC34063AP do not specify RoHS status in available documentation. Verify RoHS compliance requirements for your application before final part selection.

Q: What is the significance of the 2.5V minimum input voltage for NJM2360D?

A: The NJM2360D supports input voltages as low as 2.5V, while all substitute parts require minimum 3V input. For applications operating between 2.5V and 3V input, the NJM2360D is the only option among these parts. For applications with 3V or higher input voltage, all substitutes are compatible.

Q: Can I use MC33063AP as a direct replacement for NJM2360D?

A: MC33063AP provides functional equivalence in topology, output current, and package. However, it is an Obsolete product with limited future availability. The switching frequency is fixed at 100kHz, whereas NJM2360D supports 100Hz ~ 100kHz range. Use MC33063AP only when Active alternatives are unavailable and your circuit design accommodates 100kHz fixed frequency operation.
