MTQ-L4G1-B02 Equivalent & Substitute Parts

Part Overview

The MTQ-L4G1-B02 is a cellular 4G LTE CAT-4 RF transceiver module manufactured by Multi-Tech Systems Inc. as part of the MultiTech Dragonfly™ series. This chassis-mount module supports AT&T and Verizon networks across multiple frequency bands (700MHz, 800MHz, 850MHz, 900MHz, 1.7GHz, 1.8GHz, 1.9GHz, 2.1GHz, 2.3GHz, 2.5GHz, 2.6GHz) with a maximum data rate of 150Mbps. The MTQ-L4G1-B02 is classified as obsolete. Substitute parts are necessary to ensure continued component availability for new designs and ongoing system support where the original part is no longer in active production.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTQ-L4G1-B02 is determined by strict equivalence across the following critical parameters:

• RF Protocol & Frequency Coverage: All substitute parts maintain identical 4G LTE CAT-4 (AT&T/Verizon) and HSPA+ protocol support with matching frequency band coverage (700MHz through 2.6GHz)
• Data Rate: All substitutes deliver 150Mbps maximum data rate
• Serial Interface Compatibility: UART and USB interfaces are preserved across all substitute parts
• Power Supply Range: 3.3V to 5V supply voltage is consistent
• Operating Temperature Range: -40°C to 85°C thermal specification is maintained
• Mechanical Form Factor: Chassis mount configuration and module package type are identical
• Antenna Configuration: All parts operate without integrated antenna

The substitute parts MTQ-L4G1-B02.R1A and MTQ-L4G1-B02.R2 are direct functional equivalents within the MultiTech Dragonfly™ series, differing only in product status and packaging designation.

Parameter Comparison

Engineering Selection Recommendations

MTQ-L4G1-B02.R1A is the primary substitute for new designs and component replacement. This part maintains active product status and carries ROHS3 compliance certification with REACH unaffected status. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling. Current inventory of 810 units supports immediate procurement.

MTQ-L4G1-B02.R2 is an alternative substitute with identical electrical and mechanical specifications to MTQ-L4G1-B02.R1A. This variant also maintains active product status with ROHS3 compliance and REACH unaffected designation. Higher inventory availability of 1445 units provides extended supply assurance. Selection between MTQ-L4G1-B02.R1A and MTQ-L4G1-B02.R2 is determined by packaging requirements and supply chain logistics rather than functional performance.

Both substitute parts are suitable for direct replacement in applications currently utilizing the obsolete MTQ-L4G1-B02, provided that mechanical mounting interfaces and connector compatibility are verified at the system integration level.

Frequently Asked Questions (FAQ)

Q: Can MTQ-L4G1-B02.R1A and MTQ-L4G1-B02.R2 be used interchangeably with the original MTQ-L4G1-B02?

A: Yes. Both substitute parts are functionally equivalent across all critical parameters including RF protocol, frequency band coverage, data rate, serial interfaces, power supply range, and operating temperature specifications. The substitutes differ only in product status (active versus obsolete) and compliance certifications, not in electrical or mechanical performance.

Q: What is the difference between MTQ-L4G1-B02.R1A and MTQ-L4G1-B02.R2?

A: Both parts are electrically and mechanically identical. The primary differences are packaging designation (both listed as Bulk) and inventory levels. MTQ-L4G1-B02.R2 has higher current stock availability (1445 units versus 810 units). Selection between these variants should be based on procurement quantity requirements and supply chain preferences.

Q: Are the substitute parts compliant with environmental regulations?

A: Both MTQ-L4G1-B02.R1A and MTQ-L4G1-B02.R2 are ROHS3 compliant and REACH unaffected. Both carry MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations during storage and handling.

Q: What serial interfaces are supported by the substitute parts?

A: Both substitute parts support UART and USB serial interfaces, identical to the original MTQ-L4G1-B02. System integration must account for the specific interface requirements of the target application.

Q: Is an external antenna required for these modules?

A: Yes. All three parts (original and substitutes) operate without integrated antenna. External antenna selection and integration are required for system deployment.

Q: What is the power supply requirement for these modules?

A: All parts operate within a 3.3V to 5V supply voltage range. System power delivery design must accommodate this specification.
