SP706TEN-L Equivalent & Substitute Parts

Part Overview

The SP706TEN-L is a single-channel power management supervisor IC manufactured by MaxLinear, Inc., housed in an 8-SOIC surface mount package. This device monitors a single voltage supply and provides active-low reset output with a 140ms minimum reset timeout, operating across the industrial temperature range of -40°C to 85°C. The SP706TEN-L is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the SP706TEN-L is determined by strict alignment of the following critical parameters:

Voltage Threshold: 3.08V (exact match required)
Number of Voltages Monitored: 1 channel
Reset Type: Active Low
Package / Case: 8-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount
Operating Temperature Range: -40°C ~ 85°C (TA) or wider
Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed below meet these core electrical and mechanical parameters. Variations in reset timeout (130ms to 160ms minimum), output configuration (Push-Pull/Totem Pole vs. open-drain), and product status (Active vs. Obsolete) are noted in the comparison table. Parts with active product status and RoHS3 compliance are preferred for new designs.

Engineering Selection Recommendations

For applications requiring the SP706TEN-L, the following selection criteria apply:

Industrial Temperature Range (-40°C ~ 85°C): Select from STM706TM6F, ADM706TARZ, ADM706TARZ-REEL, DS1706TESA+, DS1706TESA+T&R, MAX706ATESA+, MAX706ATESA+T, or MAX706TESA+. These parts maintain full operational specifications across the extended temperature range.

Commercial Temperature Range (0°C ~ 70°C): MAX706TCSA+ and MAX706TCSA+T are suitable only for applications with restricted temperature requirements.

Active Product Status: All substitute parts listed carry Active product status, ensuring long-term availability and manufacturing support compared to the obsolete SP706TEN-L.

RoHS3 Compliance: All substitute parts are RoHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements.

Reset Timeout Tolerance: The SP706TEN-L specifies 140ms minimum reset timeout. DS1706TESA+ and DS1706TESA+T&R provide 130ms minimum (shorter), while ADM706TARZ and ADM706TARZ-REEL provide 160ms minimum (longer). Verify timing requirements in system design before selection.

Output Configuration: All substitute parts feature Push-Pull/Totem Pole output, providing active drive capability on both high and low states, which may differ from the original SP706TEN-L output characteristics.

Packaging Format: STM706TM6F, ADM706TARZ-REEL, DS1706TESA+T&R, MAX706ATESA+T, MAX706TCSA+T, and MAX706TESA+ are available in Cut Tape (CT) & Digi-Reel® format for automated assembly. ADM706TARZ, DS1706TESA+, MAX706ATESA+, MAX706TCSA+, and MAX706TESA+ are available in Tube packaging.

Frequently Asked Questions (FAQ)

Q: Can I directly replace SP706TEN-L with any of these substitute parts?

A: Direct replacement is possible only if the substitute part meets all critical parameters: 3.08V threshold, 1-channel monitoring, active-low reset, 8-SOIC package, and -40°C to 85°C operating range. All listed parts meet these core requirements. However, verify output configuration compatibility and reset timeout tolerance in your specific application.

Q: What is the difference between parts with different reset timeouts (130ms, 140ms, 160ms)?

A: Reset timeout specifies the minimum duration the reset output remains asserted after the monitored voltage crosses the threshold. Shorter timeouts (130ms) release reset sooner; longer timeouts (160ms) hold reset longer. Select based on your system's power-up sequencing requirements.

Q: Why do some parts have Push-Pull/Totem Pole output while the original SP706TEN-L does not specify this?

A: The SP706TEN-L output type is not specified in the provided data. Substitute parts with Push-Pull/Totem Pole output actively drive both high and low logic states, providing stronger signal integrity compared to open-drain configurations. Verify compatibility with your reset input circuit design.

Q: Are the MAX706TCSA+ and MAX706TCSA+T suitable for industrial applications?

A: No. These parts operate only across 0°C to 70°C, which is the commercial temperature range. For industrial applications requiring -40°C to 85°C operation, select from the remaining substitute parts.

Q: What is the difference between Tube and Cut Tape (CT) & Digi-Reel® packaging?

A: Tube packaging is used for manual assembly and lower-volume applications. Cut Tape & Digi-Reel® packaging is optimized for automated pick-and-place assembly in high-volume production. Both contain identical components; packaging choice depends on assembly method and volume requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: Which substitute part is the closest match to SP706TEN-L?

A: STM706TM6F and MAX706ATESA+ / MAX706ATESA+T / MAX706TESA+ provide the closest electrical match, with identical 3.08V threshold, 140ms reset timeout, and -40°C to 85°C operating range. STM706TM6F is available in Cut Tape format for automated assembly.
