SP707CN-L/TR Equivalent & Substitute Parts

Part Overview

The SP707CN-L/TR is a single-channel power supply supervisor IC manufactured by MaxLinear, Inc., designed for power management applications requiring reset signal generation and voltage monitoring. This device operates as a simple reset/power-on reset supervisor with an active high/active low reset output. The SP707CN-L/TR is classified as obsolete, which necessitates identification of functionally equivalent active alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage threshold, reset timeout, output characteristics, and mechanical packaging specifications.

Engineering Selection Recommendations

Primary Recommendation: SP707EN-L/TR

The SP707EN-L/TR is the direct MaxLinear equivalent with identical electrical specifications to the SP707CN-L/TR. This part maintains the same voltage threshold (4.65V), reset timeout (140ms minimum), and 8-SOIC package footprint. The SP707EN-L/TR is active in production with extended operating temperature range (-40°C ~ 85°C), providing superior thermal coverage for industrial and extended-temperature applications. This represents the lowest-risk substitution path.

Secondary Recommendations: Analog Devices / Maxim Integrated Family

The MAX707ESA+ and MAX707ESA+T devices from Analog Devices Inc./Maxim Integrated provide functional equivalence with matching 4.65V threshold and 140ms reset timeout. These parts feature Push-Pull output configuration and active product status with ROHS3 compliance. The MAX707ESA+T variant is available in Cut Tape & Digi-Reel packaging for high-volume production environments.

The DS1707ESA+ and DS1707ESA+T&R (MicroMonitor™ series) offer 4.65V threshold compatibility with a 130ms reset timeout, which is within acceptable margin for most applications. These devices provide Push-Pull output and are available in both Tube and Tape & Reel packaging formats.

The ADM707ARZ and ADM707ARZ-REEL from Analog Devices provide 4.65V threshold with 160ms reset timeout and Push-Pull output. These parts support extended temperature operation and ROHS3 compliance.

Alternative Recommendation: Microchip Technology MIC707MY

The MIC707MY from Microchip Technology maintains 4.65V threshold and 140ms reset timeout with Complementary output configuration. This device is active in production with ROHS3 compliance and extended temperature range (-40°C ~ 85°C).

Alternative Recommendation: STMicroelectronics STM707M6F

The STM707M6F from STMicroelectronics provides 4.63V threshold (within acceptable tolerance) and 140ms reset timeout with Push-Pull/Totem Pole output. This device is available in Tape & Reel packaging and maintains ROHS3 compliance with extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can the SP707EN-L/TR directly replace the SP707CN-L/TR in existing designs?

A: Yes. The SP707EN-L/TR maintains identical voltage threshold (4.65V), reset timeout (140ms minimum), reset polarity (Active High/Active Low), and 8-SOIC package specifications. The extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C) provides additional thermal margin without affecting circuit compatibility.

Q: What is the difference between Push-Pull, Complementary, and Totem Pole output configurations?

A: These terms describe the internal output stage topology. Push-Pull and Totem Pole configurations provide similar drive capability for reset signal generation. Complementary output provides an alternative topology. All three configurations support the active high/active low reset functionality required by the SP707CN-L/TR application. Selection depends on specific circuit requirements for output impedance and drive current.

Q: Are packaging format differences (Tube, Tape & Reel, Cut Tape & Digi-Reel) electrically significant?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical specifications and functional performance remain identical across all packaging variants of the same part number.

Q: Does the STM707M6F voltage threshold of 4.63V create compatibility issues?

A: The STM707M6F threshold of 4.63V represents a 0.02V deviation from the SP707CN-L/TR specification of 4.65V. This difference is within typical manufacturing tolerance for supervisor ICs and does not create functional incompatibility for standard power supply monitoring applications.

Q: Which substitute part offers the best long-term availability?

A: The SP707EN-L/TR from MaxLinear, Inc. is the direct equivalent with active product status. The MAX707ESA+T from Analog Devices/Maxim Integrated offers high inventory levels (17,900 units) and active production status, providing strong long-term supply assurance.

Q: Can I use substitute parts with extended temperature ranges in designs originally specified for 0°C ~ 70°C operation?

A: Yes. Extended temperature range parts (-40°C ~ 85°C) are fully compatible with applications designed for narrower temperature ranges. The extended specification provides additional thermal margin without affecting performance within the original operating window.

Q: Are there RoHS compliance differences between the SP707CN-L/TR and substitute parts?

A: The SP707CN-L/TR product status is listed as obsolete without explicit RoHS designation. All active substitute parts listed (SP707EN-L/TR, ADM707ARZ, DS1707ESA+, MAX707ESA+, MIC707MY, STM707M6F) carry ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and production.
