SP706SEU-L Equivalent & Substitute Parts

Part Overview

The SP706SEU-L is a single-channel power management supervisor IC manufactured by MaxLinear, Inc., designed for reset and power-on reset applications. This part operates with a 2.93V voltage threshold and provides active-low reset output with a 140ms minimum reset timeout. The SP706SEU-L is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts maintain core functional parameters while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SP706SEU-L is determined by the following critical parameters:

• Voltage threshold: 2.93V (all substitutes match)
• Reset type: Active Low (all substitutes match)
• Reset timeout: 140ms minimum (all substitutes meet or exceed)
• Package: 8-TSSOP, 8-MSOP form factor (all substitutes compatible)
• Single-channel voltage monitoring (all substitutes match)
• Surface mount technology (all substitutes match)

Substitute parts are grouped into two categories based on output configuration and operating temperature range:

Category 1 - MaxLinear SP706 Series (Open-Drain Output): SP706SCU-L/TR maintains the original open-drain output architecture with active product status and extended temperature range support (-40°C to 85°C).

Category 2 - Analog Devices MAX706/DS1706 Series (Push-Pull/Totem Pole Output): MAX706SEUA+, MAX706SCUA+, MAX706SCUA+T, MAX706SEUA+T, and DS1706SEUA+ provide push-pull totem pole output configuration, offering enhanced drive capability. These parts are available in both commercial (0°C to 70°C) and industrial (-40°C to 85°C) temperature grades.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Matching Output Architecture): SP706SCU-L/TR is the primary active substitute for SP706SEU-L, maintaining open-drain output configuration. This part is suitable for applications operating within the 0°C to 70°C commercial temperature range. For industrial applications requiring -40°C to 85°C operation, the original SP706SEU-L specifications cannot be directly matched within the MaxLinear SP706 series.

For Enhanced Performance (Push-Pull Output): MAX706SEUA+ and MAX706SEUA+T provide industrial temperature range (-40°C to 85°C) with push-pull totem pole output, delivering higher drive capability than open-drain configurations. Both parts are ROHS3 compliant and REACH unaffected. MAX706SEUA+T is supplied in tape and reel packaging for automated assembly.

For Commercial Temperature Applications: MAX706SCUA+ and MAX706SCUA+T are suitable for 0°C to 70°C operating environments. MAX706SCUA+T offers tape and reel packaging for production environments.

For Extended Reset Timeout Tolerance: DS1706SEUA+ provides 130ms minimum reset timeout, which is acceptable for applications where the SP706SEU-L 140ms specification can accommodate shorter timeout margins. This part operates across -40°C to 85°C and includes ROHS3 compliance.

All substitute parts maintain the critical 2.93V voltage threshold, active-low reset configuration, and single-channel monitoring architecture required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can MAX706 series parts directly replace SP706SEU-L? A: MAX706 parts are functionally equivalent for reset and power-on reset applications with matching 2.93V threshold and active-low reset. The primary difference is output configuration: MAX706 uses push-pull totem pole output versus SP706's open-drain output. This provides higher drive capability but requires circuit verification for pull-up resistor requirements.

Q: What is the difference between open-drain and push-pull output? A: Open-drain output (SP706 series) requires external pull-up resistor to pull the output high. Push-pull totem pole output (MAX706/DS1706 series) actively drives both high and low states without external pull-up, providing faster switching and higher current capability.

Q: Which substitute supports industrial temperature range (-40°C to 85°C)? A: MAX706SEUA+, MAX706SEUA+T, and DS1706SEUA+ all support -40°C to 85°C operation. SP706SCU-L/TR is limited to 0°C to 70°C commercial range.

Q: Are all substitutes RoHS compliant? A: MAX706SEUA+, MAX706SCUA+, MAX706SCUA+T, MAX706SEUA+T, and DS1706SEUA+ are ROHS3 compliant. SP706SCU-L/TR RoHS status is not specified in available documentation.

Q: What is the difference between tube and tape & reel packaging? A: Tube packaging (standard) is suitable for manual assembly and lower-volume applications. Tape & reel packaging (TR designation) is optimized for automated pick-and-place assembly in high-volume production environments.

Q: Can DS1706SEUA+ be used if reset timeout is critical? A: DS1706SEUA+ specifies 130ms minimum reset timeout versus SP706SEU-L's 140ms minimum. For applications with strict timeout requirements, verify that 130ms meets system specifications before substitution.

Q: Are there REACH compliance considerations? A: MAX706 and DS1706 series parts are REACH unaffected. SP706SCU-L/TR REACH status is not specified.
