SP3088EMN-L Equivalent & Substitute Parts

Part Overview

The SP3088EMN-L is a half-duplex RS422/RS485 transceiver IC manufactured by MaxLinear, Inc., housed in an 8-SOIC surface mount package. This device functions as a 1/1 transceiver (one driver and one receiver) for serial communication applications requiring robust noise immunity and extended temperature operation.

The SP3088EMN-L is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing system maintenance, design revisions, and procurement continuity where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP3088EMN-L is determined by the following critical parameters:

• Protocol Compatibility: Both main and substitute parts must support RS422 and RS485 protocols
• Transceiver Configuration: 1/1 driver/receiver topology with half-duplex operation
• Electrical Specifications: Receiver hysteresis of 100 mV, data rate of 20 Mbps, and supply voltage range of 4.5V ~ 5.5V
• Package Compatibility: 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width)
• Thermal Performance: Operating temperature range must accommodate the application requirements

The SP3088EEN-L qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status and operating temperature range, which affects long-term availability and application suitability.

Parameter Comparison

Engineering Selection Recommendations

The SP3088EEN-L is the qualified substitute for the SP3088EMN-L based on electrical and mechanical parameter equivalence. Key selection factors:

Product Status: The SP3088EEN-L carries Active status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment for new designs and production continuity.

Operating Temperature Consideration: The SP3088EMN-L supports -40°C ~ 125°C operation, while the SP3088EEN-L supports -40°C ~ 85°C. Applications requiring operation above 85°C must evaluate thermal requirements against the substitute's maximum rating.

Compliance: The SP3088EEN-L is ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory standards for component procurement.

Inventory Status: The SP3088EEN-L maintains active inventory (4298 Pcs), providing reliable procurement availability compared to the obsolete SP3088EMN-L.

Frequently Asked Questions (FAQ)

Q: Can the SP3088EEN-L directly replace the SP3088EMN-L in existing designs?

A: Yes, for applications operating within -40°C ~ 85°C. The SP3088EEN-L matches all critical electrical parameters (protocol, data rate, supply voltage, receiver hysteresis) and package specifications. Applications requiring operation above 85°C require thermal analysis to confirm compatibility.

Q: Are there package differences between these parts?

A: No. Both parts use the 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width). PCB layout and footprints are interchangeable.

Q: What is the significance of the operating temperature difference?

A: The SP3088EMN-L supports extended temperature operation to 125°C, while the SP3088EEN-L maximum is 85°C. For applications operating in the 85°C ~ 125°C range, the SP3088EMN-L specification must be maintained or alternative parts evaluated.

Q: Why is the SP3088EMN-L obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The SP3088EEN-L represents the active equivalent, ensuring continued availability and regulatory compliance for new procurement.

Q: Are there compliance differences?

A: The SP3088EEN-L is certified ROHS3 compliant and REACH unaffected. The SP3088EMN-L compliance status is not specified in available documentation. For regulated applications, the SP3088EEN-L provides documented compliance assurance.
