SP707CU-L Equivalent & Substitute Parts

Part Overview

The SP707CU-L is a single-channel supervisor IC manufactured by MaxLinear, Inc., designed for power management and reset control applications. This device monitors a single voltage threshold at 4.65V and provides active high/active low reset outputs with a 140ms minimum reset timeout. The SP707CU-L is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SP707CU-L is determined by the following critical parameters:

• Single-channel voltage monitoring capability
• 4.65V threshold voltage
• Active high/active low reset output configuration
• 140ms minimum reset timeout
• Surface mount packaging with 8-pin configuration
• MSL Level 1 rating

The SP707CU-L has two manufacturer-recommended substitutes: SP707EN-L/TR and MAX707EUA+. Both alternatives maintain the core functional specifications while offering different packaging and operational temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

SP707EN-L/TR is the manufacturer-recommended primary substitute for the SP707CU-L. Both devices share the same base product number (SP707) and maintain identical functional specifications including voltage threshold, reset timing, and monitoring capability. The SP707EN-L/TR offers an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and is currently in active production status with RoHS compliance certification. The primary design consideration is package footprint: SP707EN-L/TR uses 8-SOIC (0.154", 3.90mm width) versus the original 8-MSOP (0.118", 3.00mm width), requiring PCB layout verification.

MAX707EUA+ is an alternative substitute manufactured by Analog Devices Inc./Maxim Integrated. This device maintains the same 8-MSOP package footprint as the original SP707CU-L, eliminating PCB redesign requirements. MAX707EUA+ is actively produced and ROHS3 compliant. Selection between SP707EN-L/TR and MAX707EUA+ depends on whether package footprint compatibility or extended temperature range is the primary design constraint.

Frequently Asked Questions (FAQ)

Q: Can SP707EN-L/TR be used as a direct replacement for SP707CU-L?

A: SP707EN-L/TR is functionally equivalent and maintains all critical electrical specifications. However, the package footprint differs: 8-SOIC (0.154", 3.90mm width) versus 8-MSOP (0.118", 3.00mm width). PCB layout modification is required.

Q: What is the primary advantage of MAX707EUA+ over SP707EN-L/TR?

A: MAX707EUA+ retains the original 8-MSOP package footprint, allowing direct PCB placement without layout changes. Both devices are actively produced and meet current compliance standards.

Q: Are there temperature range differences between substitutes?

A: Yes. SP707CU-L operates 0°C to 70°C. SP707EN-L/TR extends this to -40°C to 85°C, providing broader environmental coverage. MAX707EUA+ temperature specifications are not provided in the available data.

Q: Do all substitutes maintain the same reset timeout specification?

A: SP707CU-L and SP707EN-L/TR both specify 140ms minimum reset timeout. MAX707EUA+ timeout specification is not provided in the available data.

Q: What compliance certifications apply to the substitutes?

A: SP707EN-L/TR is RoHS Compliant. MAX707EUA+ is ROHS3 Compliant. Both maintain MSL Level 1 rating.
