Key Parameters

Substitute Part Grouping Explanation

Substitution of the NL-SW-LTE-S7648 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LTE cellular protocol support with AT&T/T-Mobile network compatibility
• Through-hole mounting configuration matching 20-DIP module form factor
• Serial interface support (UART and USB)
• Voltage supply range of 3V to 5.5V
• Operating temperature range of -40°C to 85°C
• U.FL antenna connector interface

Substitution Logic: The NL-SW-LTE-SRC7611-4 qualifies as a manufacturer-recommended substitute because it maintains compatibility across all critical mechanical and electrical parameters. While the substitute operates across a broader frequency range (617MHz ~ 2.2GHz) and provides enhanced performance specifications (150Mbps data rate, 24dBm output power, -100.5dBm sensitivity), it preserves the essential interface requirements, mounting configuration, and supply voltage specifications required for direct replacement in existing designs.

Interface & Mechanical Compatibility: The substitute preserves all critical interface specifications including UART and USB serial connectivity, through-hole mounting configuration, 20-DIP module form factor, and U.FL antenna connector support.

Electrical Specifications: The substitute operates within the identical voltage supply range (3V ~ 5.5V) and temperature operating window (-40°C ~ 85°C), ensuring direct compatibility with existing power distribution and thermal management designs.

Performance Enhancement: The substitute provides improved performance characteristics including expanded frequency coverage (617MHz ~ 2.2GHz), higher data rate capability (150Mbps), and specified output power and sensitivity metrics, representing a performance upgrade path for legacy designs.

Frequently Asked Questions (FAQ)

Q: Can the NL-SW-LTE-SRC7611-4 be used as a direct replacement for the NL-SW-LTE-S7648?

A: Yes. Both parts share identical mounting type (through-hole), package configuration (20-DIP module), serial interfaces (UART, USB), voltage supply range (3V ~ 5.5V), and operating temperature specifications (-40°C ~ 85°C). The substitute maintains U.FL antenna connector compatibility and is electrically compatible with existing designs.

Q: What are the key differences between these two modules?

A: The primary differences are frequency coverage, data rate, and performance specifications. The NL-SW-LTE-S7648 operates at 700MHz, 1.7GHz, and 2.1GHz with 10Mbps data rate. The NL-SW-LTE-SRC7611-4 covers 617MHz ~ 2.2GHz with 150Mbps data rate and includes specified output power (24dBm) and sensitivity (-100.5dBm) metrics. The substitute also includes integrated antenna capability in addition to U.FL connector support.

Q: Are there any packaging or handling differences?

A: Both parts maintain identical MSL ratings of 1 (Unlimited), indicating equivalent moisture sensitivity and handling requirements. The substitute is supplied in box packaging while the main part packaging is not specified. No additional handling precautions are required for substitution.

Q: Does the substitute support AT&T and T-Mobile networks?

A: The substitute operates under the LTE protocol with frequency coverage spanning 617MHz ~ 2.2GHz, which encompasses the AT&T and T-Mobile network bands. The expanded frequency range provides broader network compatibility compared to the main part's specified bands.

Q: What is the compliance status of the substitute?

A: The NL-SW-LTE-SRC7611-4 maintains ROHS3 compliance, representing current RoHS standards. Both parts are classified under identical ECCN (5A992C) export control categories, confirming equivalent regulatory treatment.
