SP708EN-L/TR Equivalent & Substitute Parts

Part Overview

The SP708EN-L/TR is a single-channel supervisor IC manufactured by MaxLinear, Inc., designed for power management and reset control applications. This device operates as a simple reset/power-on reset supervisor with an active high/active low reset output, monitoring a single voltage threshold at 4.4V. The part is actively produced and RoHS compliant, with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and functional characteristics within the supervisor IC category.

Substitute Part Grouping Explanation

Substitution of the SP708EN-L/TR is determined by the following critical parameters:

Voltage Threshold: 4.4V (primary functional requirement)
Reset Timeout: 140ms Minimum (timing specification)
Operating Temperature Range: -40°C ~ 85°C (environmental compatibility)
Package / Case: 8-SOIC form factor (physical and electrical compatibility)
Reset Output Type: Active High/Active Low capability
RoHS Compliance: Required for regulatory alignment

Substitute parts are grouped into two categories based on voltage threshold alignment:

Group 1 - Direct Voltage Threshold Match (4.4V): MAX708ESA+T, MAX708ESA+, MAX708CSA+, MIC708MY-TR, and STM708M6F maintain the identical 4.4V threshold specification, ensuring functional equivalence for applications requiring this specific monitoring level.

Group 2 - Alternative Voltage Thresholds: ADM708ARZ (4.4V), ADM708RARZ (2.63V), and ADM708SARZ-REEL (2.93V) provide substitution options with different voltage monitoring levels, suitable for applications with alternative threshold requirements while maintaining package and reset timing compatibility.

Engineering Selection Recommendations

Direct Substitutes (Preferred for Functional Equivalence)

MAX708ESA+T and MAX708ESA+ are functionally equivalent to SP708EN-L/TR, matching the 4.4V voltage threshold, 140ms reset timeout, and -40°C to 85°C operating range. Both parts are ROHS3 compliant and actively produced. MAX708ESA+T is supplied in Cut Tape & Digi-Reel packaging with 61,050 units in stock, while MAX708ESA+ is supplied in Tube packaging with 4,450 units available.

MIC708MY-TR from Microchip Technology provides functional equivalence with identical voltage threshold (4.4V), reset timeout (140ms), and operating temperature range (-40°C ~ 85°C). This part is supplied in Tape & Reel packaging with 4,000 units in stock and is ROHS3 compliant.

STM708M6F from STMicroelectronics operates at 4.38V threshold (within acceptable tolerance of 4.4V specification), maintains 140ms reset timeout, and supports the full -40°C to 85°C temperature range. This part is ROHS3 compliant with 4,731 units in stock.

Alternative Voltage Threshold Options

ADM708ARZ and ADM708ARZ-REEL from Analog Devices Inc. match the 4.4V threshold but specify 160ms minimum reset timeout (20ms longer than SP708EN-L/TR). Both are ROHS3 compliant and support -40°C to 85°C operation. ADM708ARZ-REEL offers higher inventory (50,100 units) in Cut Tape & Digi-Reel format.

ADM708RARZ and ADM708RARZ-REEL operate at 2.63V threshold with 160ms reset timeout, suitable for applications requiring lower voltage monitoring. Both are ROHS3 compliant with -40°C to 85°C operating range.

ADM708SARZ-REEL operates at 2.93V threshold with 160ms reset timeout, providing an intermediate voltage monitoring option. This part is ROHS3 compliant with 25,200 units in stock.

MAX708CSA+ is functionally equivalent at 4.4V threshold and 140ms timeout but operates over a narrower temperature range (0°C ~ 70°C), limiting its use to commercial temperature applications only.

Frequently Asked Questions (FAQ)

Q: Can MAX708ESA+T directly replace SP708EN-L/TR?

A: Yes. MAX708ESA+T matches the critical specifications: 4.4V voltage threshold, 140ms reset timeout, -40°C to 85°C operating temperature, 8-SOIC package, and RoHS compliance. The primary difference is output type (Push-Pull vs. unspecified in SP708EN-L/TR), which is functionally compatible for standard reset applications.

Q: What is the difference between ADM708ARZ and ADM708ARZ-REEL?

A: Both parts are electrically identical with 4.4V threshold and 160ms reset timeout. The difference is packaging: ADM708ARZ is supplied in Tube format, while ADM708ARZ-REEL is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly process requirements and inventory needs.

Q: Why do some substitutes have 160ms reset timeout instead of 140ms?

A: The ADM708 series from Analog Devices Inc. specifies 160ms minimum reset timeout, which is 20ms longer than the SP708EN-L/TR specification. This longer timeout is acceptable for most applications but should be verified against circuit timing requirements before substitution.

Q: Can I use ADM708RARZ (2.63V threshold) in place of SP708EN-L/TR (4.4V threshold)?

A: No. The voltage threshold is a primary functional parameter. ADM708RARZ monitors a different voltage level (2.63V) and is suitable only for applications requiring that specific threshold. Using it in a 4.4V monitoring application will result in incorrect reset behavior.

Q: Is MAX708CSA+ suitable for all applications requiring SP708EN-L/TR?

A: MAX708CSA+ is functionally equivalent at 4.4V threshold and 140ms timeout but operates only over 0°C to 70°C temperature range. It is suitable for commercial temperature applications only and cannot be used in industrial or extended temperature environments requiring -40°C to 85°C operation.

Q: What packaging options are available for direct substitutes?

A: Direct substitutes are available in multiple packaging formats: MAX708ESA+T (Cut Tape & Digi-Reel), MAX708ESA+ (Tube), MIC708MY-TR (Tape & Reel), and STM708M6F (Cut Tape). Selection depends on assembly process compatibility and volume requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are either RoHS Compliant or ROHS3 Compliant, meeting regulatory requirements equivalent to or exceeding the SP708EN-L/TR specification.
