Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SP3085EMN-L is determined by strict alignment across the following critical parameters:

• Protocol support (RS422/RS485 half-duplex operation)
• Driver and receiver configuration (1/1)
• Data rate capability (500 kbps minimum)
• Supply voltage range (4.5V to 5.5V)
• Package and pinout compatibility (8-SOIC)
• Receiver hysteresis specification (100 mV)

The SP3085EEN-L meets all substitution criteria. While operating temperature ranges differ between the main part and substitute, both components satisfy the electrical and mechanical requirements for direct substitution in applications within the overlapping temperature window (-40°C to +85°C).

Parameter Comparison

Engineering Selection Recommendations

The SP3085EEN-L is the direct substitute for the obsolete SP3085EMN-L. Both components are manufactured by MaxLinear, Inc., and share identical electrical specifications and package configurations. The SP3085EEN-L carries active product status and ROHS3 compliance certification, making it the preferred choice for new designs and legacy system replacements.

Selection between these parts depends on application temperature requirements. The SP3085EMN-L supports operation to +125°C, while the SP3085EEN-L operates to +85°C. For applications operating within the -40°C to +85°C range, the SP3085EEN-L provides full functional equivalence with the advantage of current manufacturing support and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the SP3085EEN-L directly replace the SP3085EMN-L in existing designs?

A: Yes, for applications operating within -40°C to +85°C. Both parts share identical pinout, electrical specifications, and package dimensions. Verify your application's maximum operating temperature requirement before substitution.

Q: What is the primary difference between these two parts?

A: The SP3085EMN-L is obsolete with an extended temperature range to +125°C. The SP3085EEN-L is an active product with identical functionality, limited to +85°C maximum operating temperature, and includes ROHS3 compliance certification.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC package with 0.154" width (3.90mm). Pinout and land pattern compatibility are identical, allowing direct PCB substitution.

Q: What certifications apply to the substitute part?

A: The SP3085EEN-L is ROHS3 compliant and REACH unaffected. The main part specifications do not include these certifications.

Q: Is the data rate specification identical between both parts?

A: Yes. Both the SP3085EMN-L and SP3085EEN-L support 500 kbps data rate with identical receiver hysteresis (100 mV) and supply voltage requirements (4.5V to 5.5V).
