SP813LEP-L Equivalent & Substitute Parts

Part Overview

The SP813LEP-L is a single-channel supervisor IC manufactured by MaxLinear, Inc., designed for power management and reset signal generation in electronic systems. This device operates as a simple reset/power-on reset controller with a 4.65V voltage threshold and 140ms minimum reset timeout. The part is currently classified as obsolete, making equivalent substitute parts necessary for ongoing system support, maintenance, and new design implementations where compatible alternatives are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SP813LEP-L is determined by the following critical parameters:

• Voltage Threshold: Must be 4.65V to maintain circuit compatibility
• Reset Type: Must be Active High
• Reset Timeout: Must be 140ms minimum
• Number of Voltages Monitored: Must be 1 channel
• Operating Temperature Range: Must support -40°C ~ 85°C minimum
• Functional Type: Must be Simple Reset/Power-On Reset supervisor

Substitute parts are grouped into two categories based on mounting technology:

Category 1 - Surface Mount Alternative: SP813LEN-L/TR offers equivalent electrical specifications with 8-SOIC packaging, suitable for modern PCB designs requiring surface mount components.

Category 2 - Through Hole Alternatives: MAX813LCPA+ and MAX813LEPA+ maintain the original 8-DIP through-hole package format with push-pull totem pole output configuration, providing direct form-factor compatibility with legacy designs.

Parameter Comparison

Engineering Selection Recommendations

SP813LEN-L/TR is the manufacturer-recommended substitute for new designs and surface mount applications. This part maintains all electrical specifications of the SP813LEP-L while offering active product status and modern surface mount packaging. It is suitable for PCB redesigns or new production runs where surface mount technology is preferred.

MAX813LEPA+ is the optimal through-hole substitute for direct replacement in existing SP813LEP-L designs. This part provides identical electrical parameters, matching operating temperature range (-40°C ~ 85°C), and maintains the 8-DIP package format. It carries ROHS3 compliance and active product status, ensuring long-term availability and regulatory compliance.

MAX813LCPA+ is an alternative through-hole option with identical package and electrical specifications. However, its operating temperature range is limited to 0°C ~ 70°C, making it unsuitable for applications requiring the full -40°C ~ 85°C temperature range of the original SP813LEP-L. This part is appropriate only for temperature-constrained applications within the 0°C ~ 70°C window.

Frequently Asked Questions (FAQ)

Q: Can SP813LEN-L/TR be used as a direct replacement for SP813LEP-L in existing designs?

A: SP813LEN-L/TR is electrically equivalent but requires PCB layout modifications. The original SP813LEP-L uses 8-DIP through-hole packaging, while SP813LEN-L/TR uses 8-SOIC surface mount packaging. Direct socket substitution is not possible without redesigning the PCB footprint.

Q: What is the key difference between MAX813LCPA+ and MAX813LEPA+?

A: Both parts use identical 8-DIP through-hole packaging and share the same 4.65V threshold, 140ms reset timeout, and active-high reset configuration. The critical difference is operating temperature range: MAX813LCPA+ operates from 0°C ~ 70°C, while MAX813LEPA+ operates from -40°C ~ 85°C. For applications requiring the full temperature range of the original SP813LEP-L, MAX813LEPA+ is required.

Q: Are all substitute parts RoHS compliant?

A: MAX813LCPA+ and MAX813LEPA+ are ROHS3 compliant. SP813LEN-L/TR RoHS status is not specified in the provided data. Verify RoHS compliance requirements with your procurement or regulatory team before final component selection.

Q: Why is SP813LEP-L classified as obsolete?

A: The SP813LEP-L is obsolete and no longer manufactured. Substitute parts listed here are active products with ongoing manufacturing support and availability, ensuring supply chain continuity for system maintenance and new production requirements.

Q: Can I use MAX813LCPA+ in applications requiring -40°C operation?

A: No. MAX813LCPA+ has a minimum operating temperature of 0°C and is not rated for -40°C operation. For applications requiring -40°C ~ 85°C temperature range, use MAX813LEPA+ instead.

Q: What output configuration do the substitute parts provide?

A: MAX813LCPA+ and MAX813LEPA+ provide push-pull totem pole output configuration. SP813LEN-L/TR output configuration is not specified in the provided data. Verify output type compatibility with your circuit design requirements.
