SP706SEN-L Equivalent & Substitute Parts

Part Overview

The SP706SEN-L is a single-channel power supply supervisor IC manufactured by MaxLinear, Inc., housed in an 8-SOIC surface mount package. This component functions as a simple reset/power-on reset supervisor with a 2.93V voltage threshold and 140ms minimum reset timeout, operating across the industrial temperature range of -40°C to 85°C. The SP706SEN-L is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and production continuity. Substitute supervisors must maintain identical electrical thresholds, reset polarity, and package form factor while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the SP706SEN-L is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Voltage threshold: 2.93V
Reset polarity: Active Low
Package type: 8-SOIC (0.154", 3.90mm Width)
Mounting type: Surface Mount
Number of monitored channels: 1
Operating temperature range: -40°C ~ 85°C (TA)

Allowable Variations:

Output configuration: The SP706SEN-L has unspecified output type; substitute parts with Push-Pull/Totem Pole output are functionally compatible
Reset timeout: Substitute parts with reset timeouts between 130ms and 160ms minimum are acceptable within the supervisor function tolerance
Packaging format: Tube, Cut Tape (CT) & Digi-Reel®, or Tape & Reel (TR) formats are interchangeable for the same electrical part
Manufacturer: Analog Devices Inc./Maxim Integrated supervisors meeting all electrical and mechanical criteria are valid substitutes

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status, providing superior supply chain continuity compared to the obsolete SP706SEN-L.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and REACH unaffected status, providing immediate supply chain advantages over the obsolete SP706SEN-L. Selection among substitutes should prioritize inventory availability and packaging format requirements for your production process.

For applications requiring the full industrial temperature range (-40°C to 85°C), select from ADM706SARZ, ADM706SARZ-REEL, DS1706SESA+, DS1706SESA+T&R, MAX706ASESA+, MAX706ASESA+T, MAX706SESA+, or MAX706SESA+T. The MAX706SCSA+ and MAX706SCSA+T variants operate only across the commercial temperature range (0°C to 70°C) and are suitable only for applications not requiring extended low-temperature operation.

For highest inventory availability, MAX706SESA+T offers 106,550 pieces in stock. For applications requiring tape and reel packaging, DS1706SESA+T&R and MAX706ASESA+T provide active product status with automated assembly compatibility. The ADM706SARZ and ADM706SARZ-REEL variants from Analog Devices provide alternative sourcing with equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can I directly replace SP706SEN-L with any of these substitute parts?

A: Yes, all listed substitute parts are pin-compatible and electrically equivalent within the 8-SOIC package. The critical matching parameters are the 2.93V threshold, active-low reset polarity, and -40°C to 85°C operating range. Substitute parts with Push-Pull output are functionally compatible with designs originally using the SP706SEN-L.

Q: What is the difference between the various MAX706 part numbers?

A: MAX706 variants differ by temperature range and packaging format. The "S" suffix indicates -40°C to 85°C operation (industrial range), while "C" indicates 0°C to 70°C (commercial range). The final suffix indicates packaging: "+" denotes tube, "+T" denotes cut tape with digi-reel, and "+T&R" denotes tape and reel. All maintain identical 2.93V threshold and 140ms reset timeout.

Q: Why do some substitutes have different reset timeout values?

A: The DS1706SESA+ and DS1706SESA+T&R variants specify 130ms minimum reset timeout, compared to 140ms for the original SP706SEN-L and most MAX706 variants. This 10ms difference is within normal supervisor tolerance and does not affect functional compatibility for standard power-on reset applications.

Q: Are there compliance or certification differences between substitutes?

A: All substitute parts listed are ROHS3 compliant and REACH unaffected. The SP706SEN-L is classified as obsolete, while all substitutes are active products. This ensures long-term supply availability and compliance with current environmental regulations.

Q: Which substitute should I choose for high-volume production?

A: MAX706SESA+T is recommended for high-volume automated assembly due to its cut tape and digi-reel packaging format and highest inventory availability (106,550 pieces). For manual assembly or lower volumes, tube-packaged variants such as MAX706SESA+ or ADM706SARZ provide equivalent electrical performance with different handling requirements.

Q: Can I use MAX706SCSA+ in an application designed for -40°C operation?

A: No. MAX706SCSA+ and MAX706SCSA+T are rated only for 0°C to 70°C operation and are not suitable for applications requiring the full industrial temperature range. Use MAX706SESA+, MAX706SESA+T, MAX706ASESA+, MAX706ASESA+T, ADM706SARZ, ADM706SARZ-REEL, DS1706SESA+, or DS1706SESA+T&R for -40°C to 85°C applications.
