Engineering Selection Recommendations
For Extended Temperature Range Applications (-40°C to 85°C): DS1707ESA+, MAX707ESA+, MAX707ESA+T, and STM707M6F maintain full temperature specification compatibility with the SP707EN-L/TR. All are active products with ROHS3 compliance and MSL 1 rating. Selection among these options depends on packaging format availability and inventory requirements.
For Standard Temperature Range Applications (0°C to 70°C): MAX707CSA+ and MAX707CSA+T are suitable alternatives when extended low-temperature operation is not required. Both maintain ROHS3 compliance and MSL 1 rating.
Packaging Format Considerations:
- Tape & Reel (TR) format: SP707EN-L/TR, STM707M6F
- Cut Tape (CT) & Digi-Reel® format: MAX707CSA+T, MAX707ESA+T
- Tube format: DS1707ESA+, MAX707CSA+, MAX707ESA+
All substitute parts are active products with confirmed RoHS and MSL compliance.
Frequently Asked Questions (FAQ)
Q: Can MAX707CSA+ be used as a direct replacement for SP707EN-L/TR? A: MAX707CSA+ is electrically equivalent but operates within 0°C to 70°C. It is suitable only for applications that do not require the extended -40°C to 85°C temperature range of the SP707EN-L/TR.
Q: What is the difference between DS1707ESA+ and MAX707ESA+? A: Both maintain identical voltage threshold (4.65V), reset functionality, and operating temperature range (-40°C to 85°C). DS1707ESA+ has a 130ms minimum reset timeout compared to 140ms for MAX707ESA+. Both are packaged in Tube format and are ROHS3 compliant.
Q: Are all substitute parts pin-compatible with SP707EN-L/TR? A: All substitute parts use the 8-SOIC package with identical 0.154" (3.90mm) width. Pin compatibility must be verified against specific application schematics, as functional output configurations may vary.
Q: What packaging formats are available for extended temperature range substitutes? A: Extended temperature range (-40°C to 85°C) substitutes are available in Tape & Reel (STM707M6F), Cut Tape & Digi-Reel (MAX707ESA+T), and Tube (DS1707ESA+, MAX707ESA+) formats.
Q: Is STM707M6F a suitable alternative to SP707EN-L/TR? A: STM707M6F maintains the -40°C to 85°C operating temperature range, 4.63V voltage threshold, 140ms reset timeout, and 8-SOIC package. The 0.02V threshold difference (4.63V vs 4.65V) is within typical supervisor IC tolerance specifications. STM707M6F is available in Tape & Reel format and is ROHS3 compliant.
Q: What is the significance of MSL 1 rating for all parts? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements, providing maximum flexibility for inventory management and component storage.
