Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MTQ-LEU7-B02-SP is determined by the following critical electrical and mechanical parameters:

Primary Compatibility Factors:

• RF Family/Standard: Cellular transceiver functionality
• Frequency Band Coverage: 700MHz, 800MHz, 900MHz, 1.8GHz, 2.1GHz, 2.6GHz
• Protocol Support: LTE capability (minimum requirement)
• Serial Interfaces: UART and USB support
• Antenna Interface: U.FL Chassis Mount configuration
• Mounting Type: Chassis Mount form factor
• Operating Temperature Range: -40°C to 85°C

The substitute parts MTQ-LEU7-B02.R1A-SP and MTQ-LEU7-B02.R2-SP are both active-status revisions of the same product line. Both substitutes maintain identical frequency band coverage, serial interface specifications, antenna type, mounting configuration, and operating temperature range. The key technical distinction is protocol evolution: substitutes support LTE CAT-4 rather than HSPA+/LTE, representing enhanced cellular standard compatibility. Voltage supply compatibility requires attention: the obsolete part operates at 5V fixed supply, while substitutes support a 3.3V to 5V range, providing broader power integration flexibility.

Parameter Comparison

Engineering Selection Recommendations

The MTQ-LEU7-B02-SP is classified as Obsolete, making MTQ-LEU7-B02.R1A-SP and MTQ-LEU7-B02.R2-SP the appropriate active alternatives. Both substitute parts offer equivalent RF performance and identical physical/electrical interface specifications while maintaining active product status with current manufacturer support.

Compliance Advantages of Substitutes:

• Both MTQ-LEU7-B02.R1A-SP and MTQ-LEU7-B02.R2-SP are ROHS3 Compliant
• Both achieve Moisture Sensitivity Level 1 (Unlimited), indicating superior environmental stability
• Both carry REACH Unaffected certification status

Integration Considerations: The substitutes support a 3.3V to 5V supply voltage range compared to the obsolete part's fixed 5V requirement. This expanded range simplifies integration into systems with mixed voltage domains. Current consumption specifications (792mA for both receive and transmit modes) are explicitly documented in both substitute parts, enabling precise power budget calculations. The LTE CAT-4 protocol specification in substitutes represents an advancement from HSPA+/LTE support, providing enhanced cellular standard compatibility for future network deployments.

Frequently Asked Questions (FAQ)

Q: Are MTQ-LEU7-B02.R1A-SP and MTQ-LEU7-B02.R2-SP electrically interchangeable with the obsolete MTQ-LEU7-B02-SP?

A: Yes. Both substitutes maintain identical frequency band support (700MHz, 800MHz, 900MHz, 1.8GHz, 2.1GHz, 2.6GHz), data rate (150Mbps), serial interfaces (UART/USB), antenna type (U.FL Chassis Mount), and operating temperature range (-40°C to 85°C). The voltage supply range expansion (3.3V to 5V) provides compatibility with the original 5V specification while adding flexibility for lower-voltage integration.

Q: What is the difference between MTQ-LEU7-B02.R1A-SP and MTQ-LEU7-B02.R2-SP?

A: Both parts share identical electrical specifications, frequency bands, serial interfaces, and compliance certifications. Differentiation between these two active alternatives should be based on availability and packaging form factors. Both are suitable substitutes for the obsolete MTQ-LEU7-B02-SP.

Q: Can the obsolete MTQ-LEU7-B02-SP be directly replaced in existing designs?

A: Direct replacement is feasible for applications currently operating at 5V supply. The substitutes' expanded voltage range (3.3V to 5V) ensures compatibility. PCB-level modifications are not required as both alternatives maintain identical mounting type (Chassis Mount) and antenna interface (U.FL). Hardware integration remains unchanged.

Q: Are there any compliance differences between the obsolete part and the substitutes?

A: The substitutes provide enhanced compliance documentation. Both MTQ-LEU7-B02.R1A-SP and MTQ-LEU7-B02.R2-SP are ROHS3 Compliant and REACH Unaffected, with explicit Moisture Sensitivity Level 1 certification. The obsolete part lacks documented compliance specifications, making the substitutes preferable for regulated applications and products subject to environmental standards.

Q: What power consumption should be anticipated when using substitute parts?

A: Both substitutes specify 792mA current consumption for both receive and transmit modes. This explicit current specification enables accurate power supply dimensioning and thermal management planning. The original obsolete part did not provide current consumption data.
