SP336ECT-L/TR Equivalent & Substitute Parts

Part Overview

The SP336ECT-L/TR is a 4/4 transceiver IC supporting RS232, RS422, and RS485 protocols in a 28-SOIC surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The SP336ECT-L/TR operates across 3.3V and 5V supply voltages with a 250kbps data rate and 500mV receiver hysteresis, designed for full-duplex communication applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP336ECT-L/TR is determined by the following critical parameters:

• Protocol support (RS232, RS422, RS485 multi-protocol capability)
• Driver/receiver configuration (4/4 architecture)
• Full-duplex operation
• Data rate performance (250kbps minimum)
• Supply voltage compatibility (3.3V and 5V operation)
• Receiver hysteresis specification (500 mV)
• Surface mount capability with compatible pinout

The SP336EEY-L/TR qualifies as a direct substitute based on identical protocol support, driver/receiver count, duplex mode, data rate, supply voltage range, and receiver hysteresis. The primary difference is the package format change from 28-SOIC to 28-TSSOP, which maintains electrical equivalence while offering improved thermal characteristics and reduced board footprint.

Parameter Comparison

Engineering Selection Recommendations

The SP336EEY-L/TR is the recommended substitute for the obsolete SP336ECT-L/TR. Both parts share identical electrical specifications for protocol support, driver/receiver configuration, data rate, and supply voltage requirements, ensuring functional equivalence in circuit applications.

The SP336EEY-L/TR offers additional advantages: active product status ensures long-term availability and manufacturing support, extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), improved moisture sensitivity rating (MSL 1 versus MSL 3), and RoHS compliance certification. The package transition from 28-SOIC to 28-TSSOP reduces board space requirements while maintaining pinout compatibility for surface mount assembly.

For new designs and production transitions, the SP336EEY-L/TR provides superior supply chain stability and regulatory compliance compared to the obsolete SP336ECT-L/TR.

Frequently Asked Questions (FAQ)

Q: Are the SP336ECT-L/TR and SP336EEY-L/TR electrically equivalent?

A: Yes. Both parts support identical protocols (RS232, RS422, RS485), feature 4/4 driver/receiver configuration, operate in full-duplex mode, maintain 250kbps data rate, accept 3.3V and 5V supply voltages, and provide 500mV receiver hysteresis.

Q: What is the primary difference between these parts?

A: The package format differs. The SP336ECT-L/TR uses 28-SOIC (0.295" width), while the SP336EEY-L/TR uses 28-TSSOP (0.173" width). The TSSOP package offers reduced footprint and improved thermal performance.

Q: Can I use the SP336EEY-L/TR as a direct replacement on existing PCBs designed for the SP336ECT-L/TR?

A: Package compatibility must be verified. The 28-SOIC and 28-TSSOP packages have different physical dimensions and pin spacing. PCB layout redesign is required for package migration.

Q: Why is the SP336ECT-L/TR classified as obsolete?

A: The SP336ECT-L/TR has reached end-of-life status. The SP336EEY-L/TR represents the active product line continuation with equivalent functionality and improved specifications.

Q: Does the SP336EEY-L/TR support the same operating temperature range?

A: No. The SP336EEY-L/TR operates across -40°C ~ 85°C, exceeding the SP336ECT-L/TR range of 0°C ~ 70°C. This extended range provides greater flexibility for industrial and automotive applications.

Q: Is the SP336EEY-L/TR RoHS compliant?

A: Yes. The SP336EEY-L/TR is RoHS compliant. RoHS status for the SP336ECT-L/TR is not specified in available documentation.
