Key Parameters

Substitute Part Grouping Explanation

The SP337EBEY-L qualifies as a direct substitute for the SP337EBCY-L based on the following critical parameters:

Matching Parameters:

• Identical protocol support: RS232, RS422, RS485
• Identical driver/receiver configuration: 2/2
• Identical duplex mode: Full
• Identical receiver hysteresis: 500 mV
• Identical voltage supply range: 3.3V ~ 5V
• Identical package type: 28-TSSOP (0.173", 4.40mm Width)
• Identical mounting type: Surface Mount
• Identical moisture sensitivity level: 1 (Unlimited)

Substitution Basis: The SP337EBEY-L maintains all electrical and mechanical parameters required for functional equivalence. Both parts share the same base product number (SP337) and package footprint, ensuring PCB-level compatibility. The substitute part is available in active product status with higher inventory levels, addressing the obsolescence of the original part.

Engineering Selection Recommendations

The SP337EBEY-L is the appropriate substitute for the obsolete SP337EBCY-L. Selection is based on:

Product Status: The SP337EBEY-L maintains active product status with established supply chain availability, whereas the SP337EBCY-L is obsolete and subject to inventory depletion.

Compliance & Certifications: The SP337EBEY-L carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in most jurisdictions.

Electrical Compatibility: Both parts maintain identical protocol support, driver/receiver configuration, supply voltage range, and receiver hysteresis specifications. The SP337EBEY-L offers enhanced data rate capability (20 Mbps versus 250 kbps), which provides performance headroom without introducing incompatibility.

Thermal Operating Range: The SP337EBEY-L supports an extended operating temperature range (-40°C to 85°C) compared to the original part (0°C to 70°C), enabling deployment in broader environmental conditions.

Package & Mounting: Identical 28-TSSOP package footprint and surface mount configuration ensure direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SP337EBEY-L be used as a direct replacement for the SP337EBCY-L on existing PCBs?

A: Yes. Both parts use the 28-TSSOP package with identical pin assignments and footprint dimensions (0.173", 4.40mm width). No PCB layout changes are required.

Q: What are the key electrical parameters that make these parts equivalent?

A: The critical equivalence parameters are: RS232/RS422/RS485 protocol support, 2/2 driver/receiver configuration, full-duplex operation, 500 mV receiver hysteresis, and 3.3V to 5V supply voltage range. Both parts meet these specifications identically.

Q: Why does the SP337EBEY-L have a higher data rate specification?

A: The SP337EBEY-L supports 20 Mbps compared to the 250 kbps of the SP337EBCY-L. This represents enhanced performance capability in the substitute part. Systems designed for the original 250 kbps specification operate within the substitute's performance envelope and experience no compatibility issues.

Q: Are there any temperature-related limitations when substituting?

A: The SP337EBEY-L supports a wider operating temperature range (-40°C to 85°C) than the original part (0°C to 70°C). This provides additional thermal margin and enables operation in more demanding environments. No limitations exist for applications within the original part's temperature specification.

Q: What packaging formats are available for the SP337EBEY-L?

A: The SP337EBEY-L is supplied in tube packaging. Confirm packaging requirements with your procurement specification, as tube format is standard for this active product.

Q: Are there regulatory compliance differences between these parts?

A: The SP337EBEY-L carries ROHS3 compliance and REACH unaffected status. The original part's compliance status was not specified. For applications requiring specific regulatory certifications, confirm the SP337EBEY-L meets your system requirements.
