Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP3082EMN-L is based on the following critical parameters that must remain constant:

• Protocol compatibility: RS422/RS485
• Transceiver configuration: 1/1 (one driver, one receiver)
• Duplex mode: Half-duplex operation
• Receiver hysteresis: 100 mV
• Data rate capability: 115 Kbps minimum
• Supply voltage range: 4.5V ~ 5.5V
• Package type: 8-SOIC form factor
• Mounting method: Surface mount

The SP3082EEN-L qualifies as a direct substitute because it maintains all electrical and mechanical parameters within the specified tolerances. The primary distinction is product status: SP3082EEN-L is active and available, whereas SP3082EMN-L is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The SP3082EEN-L is the direct substitute for the obsolete SP3082EMN-L. Both parts share identical electrical specifications and package geometry, ensuring pin-for-pin compatibility and functional equivalence in RS422/RS485 applications.

The SP3082EEN-L offers the following advantages for new designs and replacement applications:

• Active product status with current manufacturing support
• ROHS3 compliance certification
• REACH unaffected status
• Identical electrical performance across all critical parameters
• Same 8-SOIC package footprint for direct PCB compatibility

The operating temperature range of SP3082EEN-L (-40°C ~ 85°C) is narrower than the SP3082EMN-L (-40°C ~ 125°C). Applications requiring operation above 85°C must evaluate this specification against system requirements.

Frequently Asked Questions (FAQ)

Q: Can SP3082EEN-L replace SP3082EMN-L in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The SP3082EEN-L is a direct pin-for-pin substitute with the same 8-SOIC package footprint, supply voltage range, protocol support, and data rate capability.

Q: What is the difference between SP3082EMN-L and SP3082EEN-L?

A: The primary differences are product status and operating temperature range. SP3082EMN-L is obsolete with a -40°C ~ 125°C operating range. SP3082EEN-L is active with a -40°C ~ 85°C operating range and includes ROHS3 compliance certification.

Q: Are there any compatibility concerns when switching from SP3082EMN-L to SP3082EEN-L?

A: No compatibility concerns exist for standard applications. Both parts maintain identical RS422/RS485 protocol support, 1/1 transceiver configuration, half-duplex operation, and 8-SOIC package specifications. Applications operating above 85°C ambient temperature should evaluate the reduced temperature range of SP3082EEN-L.

Q: What packaging options are available for SP3082EEN-L?

A: SP3082EEN-L is supplied in Tube packaging. Both parts use the same 8-SOIC (0.154", 3.90mm Width) case.

Q: Is SP3082EEN-L RoHS compliant?

A: Yes. SP3082EEN-L is ROHS3 compliant and REACH unaffected.
