Key Parameters

Substitute Part Grouping Explanation

Substitution for the SP337EBET-L is determined by electrical and functional equivalence across the following critical parameters:

• Protocol support: RS232, RS422, RS485 compatibility
• Driver/receiver configuration: 2/2 channel architecture
• Duplex capability: Full duplex operation
• Data rate: 20 Mbps minimum
• Supply voltage range: 3.3V ~ 5V operation
• Operating temperature range: -40°C ~ 85°C
• Receiver hysteresis: 500 mV threshold

The SP337EBEY-L qualifies as a direct substitute based on identical electrical specifications and protocol support. The primary difference is the package format: 28-TSSOP versus 28-SOIC. Both packages are surface mount configurations with equivalent pin counts and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SP337EBEY-L is the direct electrical equivalent for the obsolete SP337EBET-L. Selection between these parts is determined by PCB layout and assembly requirements:

SP337EBEY-L advantages: Active product status ensures long-term availability and supply chain continuity. ROHS3 compliance and improved moisture sensitivity rating (MSL 1 versus MSL 3) provide enhanced environmental performance. The 28-TSSOP package offers reduced board footprint (0.173" width versus 0.295" width).

Package consideration: The SP337EBET-L uses 28-SOIC packaging while the SP337EBEY-L uses 28-TSSOP packaging. Both are 28-pin surface mount configurations with identical electrical functionality. PCB redesign is required to accommodate the different package footprint and pin pitch.

Frequently Asked Questions (FAQ)

Q: Can SP337EBEY-L directly replace SP337EBET-L without PCB modification?

A: No. While electrically equivalent, the packages differ: 28-SOIC versus 28-TSSOP. PCB layout and footprint must be updated to accommodate the SP337EBEY-L package dimensions and pin spacing.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts support RS232, RS422, and RS485 protocols with 2/2 driver/receiver configuration, 20 Mbps data rate, full duplex operation, 500 mV receiver hysteresis, and identical supply voltage and temperature ranges.

Q: Why is SP337EBET-L classified as obsolete?

A: The SP337EBET-L has reached end-of-life status. MaxLinear, Inc. recommends transitioning to the SP337EBEY-L for new designs and production continuity.

Q: What is the difference in moisture sensitivity between these parts?

A: SP337EBET-L has MSL 3 (168-hour limit), while SP337EBEY-L has MSL 1 (unlimited). MSL 1 provides superior moisture tolerance and reduces handling constraints during assembly.

Q: Are both parts RoHS compliant?

A: SP337EBEY-L is ROHS3 compliant. RoHS status for SP337EBET-L is not specified in the available documentation.
