SP708REN-L Equivalent & Substitute Parts

Part Overview

The SP708REN-L is a single-channel power management supervisor IC manufactured by MaxLinear, Inc., housed in an 8-SOIC surface mount package. This device functions as a simple reset/power-on reset supervisor with a 2.63V voltage threshold and 140ms minimum reset timeout. The part is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and production requirements. Functionally equivalent alternatives from active manufacturers provide direct replacement capability while maintaining core electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SP708REN-L is determined by strict alignment of the following critical parameters:

Core Electrical Parameters:

• Voltage threshold: 2.63V (exact match required)
• Reset type: Active High/Active Low (exact match required)
• Number of monitored voltages: 1 channel (exact match required)
• Operating temperature range: -40°C ~ 85°C minimum (equal or wider range acceptable)
• Reset timeout: 140ms minimum or lower (equal or faster response acceptable)

Mechanical & Package Parameters:

• Package type: 8-SOIC (0.154", 3.90mm Width) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Compliance & Status:

• RoHS compliance required
• Active product status preferred for long-term availability

All substitute parts listed below meet these core criteria. Output type variations (Push-Pull, Totem Pole, Complementary) are functionally compatible at the system level when the reset signal conditioning is appropriately designed.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Compatibility):

MAX708RESA+T and MAX708RESA+ from Analog Devices Inc./Maxim Integrated provide the closest functional match to SP708REN-L. Both maintain identical voltage threshold (2.63V), reset timeout (140ms minimum), and operating temperature range (-40°C ~ 85°C). These parts carry active product status with ROHS3 compliance and REACH unaffected certification, ensuring long-term supply chain stability and regulatory compliance.

Secondary Substitutes (Temperature-Dependent):

MAX708RCSA+ and MAX708RCSA+T are functionally equivalent but operate within a narrower temperature range (0°C ~ 70°C). These parts are suitable only for applications where the full -40°C ~ 85°C range is not required. Both maintain active status and full compliance certifications.

Alternative Substitutes (Timing Variation):

DS1708RESA+ and DS1708RESA+T&R from Analog Devices Inc./Maxim Integrated (MicroMonitor™ series) feature a faster reset timeout (130ms minimum) compared to the 140ms specification of SP708REN-L. This faster response is functionally compatible and may provide improved system performance in applications sensitive to reset timing. Both parts maintain the full -40°C ~ 85°C operating range and active product status.

Packaging Considerations:

STM708RM6F (STMicroelectronics) and MIC708RMY (Microchip Technology) offer alternative sourcing from different manufacturers. STM708RM6F is available in Cut Tape & Digi-Reel packaging, while MIC708RMY is supplied in Tube format. Both maintain identical electrical specifications and active product status.

Output Type Variations:

All substitute parts feature output configurations (Push-Pull, Totem Pole, or Complementary) that differ from the SP708REN-L specification. These output types are electrically compatible when the reset signal conditioning circuit is appropriately designed for the specific output impedance and drive characteristics of the selected substitute.

Frequently Asked Questions (FAQ)

Q: Can I directly replace SP708REN-L with any of the listed substitute parts?

A: Yes, all listed parts meet the core electrical and mechanical substitution criteria: 2.63V voltage threshold, 1-channel monitoring, Active High/Active Low reset, 8-SOIC package, and surface mount configuration. However, verify that your application's operating temperature range aligns with the selected substitute. MAX708RCSA+ and MAX708RCSA+T operate only to 70°C maximum, while all other substitutes support the full -40°C ~ 85°C range.

Q: What is the difference between the output types (Push-Pull, Totem Pole, Complementary)?

A: Output type describes the reset signal driver configuration. Push-Pull and Totem Pole outputs actively drive both high and low logic states. Complementary output provides complementary signal pairs. All three types are functionally compatible in standard reset circuit designs. Verify your PCB reset signal conditioning circuit can accommodate the specific output impedance of your selected substitute.

Q: Why do some substitutes have different reset timeout specifications?

A: DS1708RESA+ and DS1708RESA+T&R specify 130ms minimum reset timeout, compared to 140ms for SP708REN-L. This 10ms difference represents faster reset assertion and is functionally compatible. If your application requires exactly 140ms or longer timeout, select MAX708RESA+, MAX708RESA+T, MAX708RCSA+, MAX708RCSA+T, STM708RM6F, or MIC708RMY.

Q: Are all substitutes RoHS compliant?

A: Yes. SP708REN-L is RoHS Compliant. All listed substitutes carry ROHS3 Compliant certification, meeting current regulatory requirements.

Q: What packaging options are available?

A: Substitutes are supplied in three packaging formats: Tube (individual packaging), Cut Tape & Digi-Reel (CT & Digi-Reel), and Tape & Reel (TR). All maintain the same 8-SOIC physical package. Select based on your procurement and assembly process requirements.

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

A: MAX708RESA+T from Analog Devices Inc./Maxim Integrated shows the highest inventory (18,100 pcs) and active product status, indicating strong long-term supply commitment. ADM708RARZ-REEL (14,347 pcs) and MAX708RCSA+T (12,200 pcs) also demonstrate robust availability.

Q: Can I use MAX708RCSA+ if my application operates below 0°C?

A: No. MAX708RCSA+ and MAX708RCSA+T are specified only for 0°C ~ 70°C operation. For applications requiring -40°C operation, select MAX708RESA+, MAX708RESA+T, DS1708RESA+, DS1708RESA+T&R, STM708RM6F, ADM708RARZ, ADM708RARZ-REEL, or MIC708RMY.
