SP3085EMN-L/TR Equivalent & Substitute Parts

Part Overview

The SP3085EMN-L/TR is a half-duplex RS422/RS485 transceiver IC manufactured by MaxLinear, Inc., housed in an 8-SOIC surface mount package. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The part operates within a 4.5V to 5.5V supply voltage range and supports data rates up to 500 kbps with a receiver hysteresis of 100 mV.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SP3085EMN-L/TR is determined by the following critical parameters:

Primary Compatibility Criteria:

• Protocol support: RS422 and RS485
• Configuration: 1/1 half-duplex transceiver
• Package type: 8-SOIC surface mount
• Supply voltage range: 4.5V ~ 5.5V
• Moisture sensitivity level: 1 (Unlimited)

Secondary Compatibility Considerations:

• Data rate capability (minimum 500 kbps required)
• Receiver hysteresis (100 mV baseline)
• Operating temperature range (minimum -40°C ~ 85°C acceptable)

The identified substitute parts maintain electrical and mechanical compatibility within these parameters while offering improved product status or enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

SP3085EEN-L (MaxLinear, Inc.)

This part is the direct equivalent from the original manufacturer with active product status. It maintains identical electrical specifications including 500 kbps data rate and 100 mV receiver hysteresis. The operating temperature range is reduced to -40°C ~ 85°C compared to the main part's -40°C ~ 125°C specification. This part carries ROHS3 compliance certification and is available in tube packaging with 3800 units in stock. Selection of this part is appropriate for applications where the reduced upper temperature limit is acceptable and where manufacturer continuity is prioritized.

SN65HVD3085ED (Texas Instruments)

This part is a cross-manufacturer substitute from Texas Instruments with obsolete product status. It provides enhanced performance with 1 Mbps data rate capability and improved receiver hysteresis of 30 mV, both superior to the main part specifications. The operating temperature range matches SP3085EEN-L at -40°C ~ 85°C. ROHS3 compliance and unlimited moisture sensitivity are maintained. Selection of this part is appropriate for applications requiring higher data rate performance or improved noise immunity, provided the reduced upper temperature limit is acceptable.

Frequently Asked Questions (FAQ)

Q: Can SP3085EEN-L be used as a direct replacement for SP3085EMN-L/TR?

A: SP3085EEN-L is electrically and mechanically compatible with SP3085EMN-L/TR. Both parts share identical protocol support (RS422/RS485), configuration (1/1 half-duplex), package type (8-SOIC), supply voltage range (4.5V ~ 5.5V), and data rate (500 kbps). The primary difference is the reduced operating temperature range (-40°C ~ 85°C versus -40°C ~ 125°C) and active product status. Compatibility depends on whether your application requires operation above 85°C.

Q: What are the performance differences between SP3085EMN-L/TR and SN65HVD3085ED?

A: SN65HVD3085ED offers higher data rate capability (1 Mbps versus 500 kbps) and improved receiver hysteresis (30 mV versus 100 mV). Both parts maintain identical supply voltage range and package specifications. The operating temperature range is identical at -40°C ~ 85°C for SN65HVD3085ED. These enhancements make SN65HVD3085ED suitable for higher-speed applications or environments requiring improved noise immunity.

Q: Are all substitute parts available in the same package?

A: Yes. SP3085EMN-L/TR, SP3085EEN-L, and SN65HVD3085ED are all housed in 8-SOIC surface mount packages with identical physical dimensions (0.154", 3.90mm width). Pin-to-pin compatibility is maintained across all three parts.

Q: What compliance certifications apply to these parts?

A: SP3085EEN-L and SN65HVD3085ED both carry ROHS3 compliance certification. All three parts maintain REACH unaffected status and unlimited moisture sensitivity level (MSL 1). ECCN classification is EAR99 for all parts.

Q: Which substitute part should be selected for new designs?

A: SP3085EEN-L is recommended for new designs as it maintains active product status and direct manufacturer support from MaxLinear, Inc. It provides identical electrical performance to the obsolete SP3085EMN-L/TR with the exception of operating temperature range. SN65HVD3085ED is appropriate when higher data rate performance or improved receiver hysteresis is required by the application.
