Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SP3080EMN-L is determined by the following critical parameters:

• Protocol Compatibility: RS422/RS485 full-duplex transceiver functionality
• Configuration: 1 driver and 1 receiver channel
• Package Type: 14-SOIC surface mount package with 0.154" (3.90mm) width
• Electrical Specifications: Supply voltage range, data rate capability, receiver hysteresis, and operating temperature range
• Mounting Technology: Surface mount compatibility for PCB integration

The MAX3080EESD+ qualifies as a manufacturer-recommended substitute based on matching protocol, configuration, package, and core electrical parameters within acceptable tolerance ranges.

Parameter Comparison

Engineering Selection Recommendations

The MAX3080EESD+ is the manufacturer-recommended substitute for the obsolete SP3080EMN-L. Selection criteria are based on the following factors:

Product Status: The SP3080EMN-L is obsolete, while the MAX3080EESD+ maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance and Certifications: The MAX3080EESD+ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both parts carry EAR99 ECCN classification and identical HTSUS codes (8542.39.0001).

Electrical Compatibility: The substitute maintains identical protocol support (RS422/RS485), channel configuration (1/1), duplex mode (full), data rate (115Kbps), and receiver hysteresis (100 mV). The supply voltage range of the MAX3080EESD+ (4.75V ~ 5.25V) is narrower than the original but encompasses the standard 5V operating point.

Temperature Consideration: The MAX3080EESD+ operates to 85°C maximum, compared to the SP3080EMN-L's 125°C upper limit. Applications requiring operation above 85°C require evaluation of alternative solutions.

Package and Mounting: Both parts use identical 14-SOIC surface mount packages with matching footprints, enabling direct PCB substitution without layout modifications.

Moisture Handling: The MAX3080EESD+ features MSL 1 (unlimited shelf life) versus MSL 2 (1-year shelf life), providing superior moisture sensitivity performance for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the MAX3080EESD+ directly replace the SP3080EMN-L on existing PCBs?

A: Yes. Both parts use identical 14-SOIC packages with matching pin configurations, footprints, and pinouts. No PCB layout modifications are required for substitution.

Q: What are the key electrical differences between these parts?

A: The primary differences are supply voltage range (SP3080EMN-L: 4.5V ~ 5.5V; MAX3080EESD+: 4.75V ~ 5.25V) and maximum operating temperature (SP3080EMN-L: 125°C; MAX3080EESD+: 85°C). All other electrical parameters, including protocol, data rate, and receiver hysteresis, are identical.

Q: Is the MAX3080EESD+ suitable for applications requiring operation above 85°C?

A: No. The MAX3080EESD+ is rated to 85°C maximum. Applications requiring sustained operation above 85°C must identify alternative solutions or confirm that peak temperatures remain within the 85°C specification.

Q: Does the narrower supply voltage range of the MAX3080EESD+ affect compatibility?

A: The MAX3080EESD+ operates within 4.75V ~ 5.25V, which encompasses standard 5V supply systems. Applications using supply voltages below 4.75V or above 5.25V require verification against the MAX3080EESD+ datasheet or identification of alternative parts.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The SP3080EMN-L carries MSL 2 (1-year shelf life), while the MAX3080EESD+ carries MSL 1 (unlimited shelf life). MSL 1 indicates superior moisture resistance and longer allowable storage periods without baking requirements, reducing handling complexity and cost.

Q: Are there any compliance or regulatory differences?

A: The MAX3080EESD+ is ROHS3 compliant and REACH unaffected, meeting current environmental standards. Both parts carry identical EAR99 ECCN and HTSUS classifications. The substitute provides enhanced regulatory alignment for new designs.

Q: What inventory considerations apply to this substitution?

A: The SP3080EMN-L is obsolete with limited remaining stock (1075 pcs). The MAX3080EESD+ is actively produced with robust availability (2100 pcs in stock). New designs should specify the MAX3080EESD+ to ensure long-term supply security.
