• Data Rate: 150Mbps
• Serial Interfaces: USB
• Antenna Type: U.FL
• Mounting Type: Through Hole
• Voltage Supply: 3.3V ~ 5V
• Operating Temperature: -40°C ~ 85°C
• Package/Case: Module
• Base Product Number: MTSMC-L4

The MTSMC-L4E1-U.R1-SP qualifies as a direct substitute based on identical alignment across all critical electrical, mechanical, and functional parameters. The primary distinction is packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The MTSMC-L4E1-U.R1-SP is the direct substitute for the obsolete MTSMC-L4E1-U-SP. Both components maintain identical electrical specifications, frequency band support, data rate capability, and mechanical mounting characteristics. The substitute part carries active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and identical moisture sensitivity classification, satisfying regulatory and environmental requirements. The primary operational difference is packaging format: the substitute is supplied in tray packaging rather than standard packaging. This distinction does not affect functional performance or electrical compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can MTSMC-L4E1-U.R1-SP directly replace MTSMC-L4E1-U-SP in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including frequency bands, data rate, voltage supply, mounting type, and antenna interface. The substitute part is functionally interchangeable.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging format. MTSMC-L4E1-U-SP uses standard packaging, while MTSMC-L4E1-U.R1-SP is supplied in tray packaging. The ".R1" designation in the part number indicates the revision level and packaging configuration. Electrical and functional specifications remain identical.

Q: Why is the original part classified as obsolete?

A: MTSMC-L4E1-U-SP is listed as obsolete, indicating it is no longer in active production. MTSMC-L4E1-U.R1-SP maintains active product status and represents the current production equivalent.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical ROHS3 compliance status and moisture sensitivity level (MSL 1). No compliance or certification differences exist between the two parts.

Q: What antenna connector type is used?

A: Both parts use U.FL antenna connectors with through-hole mounting. Antenna is not included with either part; external antenna selection must be based on application frequency requirements.

Q: What is the voltage supply range for this module?

A: Both parts operate across a 3.3V to 5V supply voltage range, providing flexibility for integration into systems with different power supply architectures.
