Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTC-LEU4-B01 is determined by the following critical parameters:

Core Functional Parameters:

• Modulation/Protocol: LTE CAT 4
• Data Rate: 150Mbps maximum throughput
• Manufacturer: Multi-Tech Systems Inc.
• RoHS Compliance: ROHS3 Compliant

Interface and Connectivity Parameters:

• Communication interface type (USB vs. RS-232)
• Supported frequency bands for LTE operation
• Supply voltage range compatibility

Compliance and Status:

• Active product status for ongoing availability
• ROHS3 compliance certification
• REACH compliance status

The MTC-L4G2D-B01 qualifies as a substitute based on identical LTE CAT 4 protocol support, matching 150Mbps data rate, ROHS3 compliance, and Multi-Tech Systems Inc. manufacture. However, interface differences (RS-232 vs. USB) and frequency band variations require evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution Consideration:

The MTC-L4G2D-B01 is an active product offering equivalent LTE CAT 4 modem functionality with identical 150Mbps data rate performance. Both devices maintain ROHS3 compliance and are manufactured by Multi-Tech Systems Inc., ensuring consistent quality standards and regulatory adherence.

Critical Differences Requiring Application Assessment:

1. Interface Protocol: The MTC-LEU4-B01 operates via USB interface, while the MTC-L4G2D-B01 uses RS-232 serial communication. System integration architecture must accommodate this interface change.

2. Frequency Band Coverage: The MTC-LEU4-B01 supports five frequency bands (700MHz, 900MHz, 1.8GHz, 2.1GHz, 2.6GHz), whereas the MTC-L4G2D-B01 operates across three bands (700MHz, 1.7GHz, 1.9GHz). Geographic deployment regions and carrier frequency allocations determine compatibility.

3. Supply Voltage Range: The MTC-LEU4-B01 requires fixed 5V supply, while the MTC-L4G2D-B01 accepts 7V to 32V input. Power distribution system design must align with the selected device specifications.

4. Product Status: The MTC-L4G2D-B01 maintains active product status, ensuring continued manufacturer support, availability, and potential firmware updates compared to the obsolete MTC-LEU4-B01.

Frequently Asked Questions (FAQ)

Q: Can the MTC-L4G2D-B01 directly replace the MTC-LEU4-B01 in existing designs?

A: Direct replacement requires interface protocol conversion from USB to RS-232 and verification that the three supported frequency bands (700MHz, 1.7GHz, 1.9GHz) align with target deployment regions. The supply voltage range difference (5V fixed vs. 7V–32V variable) also necessitates power system evaluation.

Q: What are the primary substitution criteria for LTE CAT 4 cellular modems?

A: Substitution validity is determined by LTE CAT 4 protocol compliance, 150Mbps data rate capability, interface type compatibility, supported frequency band coverage for intended geographic markets, supply voltage requirements, and regulatory compliance certifications (ROHS3, REACH).

Q: Why is the MTC-LEU4-B01 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The MTC-L4G2D-B01, as an active product, represents the current generation equivalent offering from Multi-Tech Systems Inc. for LTE CAT 4 modem applications.

Q: How do frequency band differences affect substitution feasibility?

A: LTE frequency bands are region-specific. The MTC-LEU4-B01 covers five bands while the MTC-L4G2D-B01 covers three bands. Substitution is valid only when all required frequency bands for the deployment region are present in the substitute device. Geographic carrier allocations must be cross-referenced with device specifications.

Q: What packaging differences exist between these parts?

A: The MTC-LEU4-B01 is supplied in Box packaging, while the MTC-L4G2D-B01 is supplied in Bulk packaging. Packaging selection affects inventory management, handling procedures, and component integration workflows.

Q: Are both devices RoHS compliant?

A: Yes, both the MTC-LEU4-B01 and MTC-L4G2D-B01 maintain ROHS3 compliance, ensuring adherence to hazardous substance restrictions and environmental regulatory requirements.
