Engineering Selection Recommendations

For direct replacement with extended temperature range: SP708SEN-L/TR is the primary alternative, maintaining MaxLinear manufacturing continuity while offering active product status and RoHS compliance. This part extends the operating temperature range to -40°C ~ 85°C, suitable for industrial and automotive applications.

For applications requiring industrial temperature range (-40°C ~ 85°C): MAX708SESA+, MAX708SESA+T, DS1708SESA+, DS1708SESA+T&R, MIC708SMY, MIC708SMY-TR, and STM708SAM6F all meet this requirement. All substitute parts carry active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

For applications constrained to commercial temperature range (0°C ~ 70°C): MAX708SCSA+ and MAX708SCSA+T provide direct thermal compatibility with the original SP708SCN-L/TR while offering active product status and ROHS3 compliance.

Packaging considerations: Tube packaging is available for MAX708SCSA+, DS1708SESA+, and MIC708SMY. Cut Tape (CT) & Digi-Reel® packaging is available for MAX708SCSA+T, MAX708SESA+T, and MAX708SESA+T. Tape & Reel (TR) packaging is available for SP708SEN-L/TR, DS1708SESA+T&R, MIC708SMY-TR, and STM708SAM6F.

Frequently Asked Questions (FAQ)

Q: Can SP708SCN-L/TR be directly replaced with SP708SEN-L/TR?

A: Yes. SP708SEN-L/TR is a direct MaxLinear variant with identical electrical specifications (2.93V threshold, 140ms reset timeout) and package (8-SOIC). The primary difference is extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C) and active product status. Verify your application's temperature requirements before selection.

Q: What is the difference between MAX708SCSA+ and MAX708SESA+?

A: Both parts share the 2.93V threshold and 140ms reset timeout. MAX708SCSA+ operates at 0°C ~ 70°C (commercial range), while MAX708SESA+ operates at -40°C ~ 85°C (industrial range). Select based on your application's thermal environment.

Q: Are there output type differences between substitute parts?

A: Yes. The original SP708SCN-L/TR does not specify output type. Substitute parts offer Push-Pull output (DS1708SESA+, MAX708 series), Complementary output (MIC708SMY), or Push-Pull/Totem Pole output (STM708SAM6F). Verify your circuit design requirements for output stage compatibility.

Q: Does reset timeout variation affect substitution?

A: Reset timeout specifications range from 130ms minimum (DS1708SESA+ series) to 160ms minimum (STM708SAM6F). These variations remain within typical supervisor IC tolerances. Confirm your application's reset timing requirements before final selection.

Q: Are all substitute parts RoHS compliant?

A: SP708SEN-L/TR is RoHS Compliant. All cross-manufacturer alternatives (DS1708, MAX708, MIC708, STM708 series) are ROHS3 Compliant. The original SP708SCN-L/TR does not specify RoHS status.

Q: What packaging options are available for high-volume production?

A: Tape & Reel (TR) packaging is available for SP708SEN-L/TR, DS1708SESA+T&R, MIC708SMY-TR, and STM708SAM6F. Cut Tape (CT) & Digi-Reel® packaging is available for MAX708SCSA+T, MAX708SESA+T, and MAX708SESA+T. Tube packaging is available for MAX708SCSA+, DS1708SESA+, and MIC708SMY.
