NL-S-4GT-VR Equivalent & Substitute Parts

Part Overview

The NL-S-4GT-VR is a modem kit manufactured by Airgain, designed for CAT3 LTE serial applications. This RF transceiver operates across multiple cellular frequency bands (800MHz, 900MHz, 1.9GHz, 2.1GHz) and supports EDGE and GPRS modulation protocols via USB interface. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for system redesign, legacy support, and component procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NL-S-4GT-VR is determined by the following critical parameters:

• Functional Category: RF transceiver or modem capability supporting cellular communication
• Frequency Coverage: Support for 800MHz, 900MHz, 1.9GHz, and 2.1GHz bands
• Modulation Support: EDGE and GPRS protocol compatibility
• Interface Type: USB connectivity for host integration
• Supply Voltage: Operation within 3V to 5V range
• Environmental Classification: Moisture sensitivity level compatibility

The identified substitute part TG.30.8113 is a multi-band RF antenna from Taoglas Limited. This component addresses the RF front-end requirements of the NL-S-4GT-VR by providing wide-band antenna coverage across the required frequency ranges, supporting the same cellular standards (GSM, CDMA, LTE, UMTS) necessary for EDGE and GPRS operation.

Parameter Comparison

Engineering Selection Recommendations

The NL-S-4GT-VR is obsolete and no longer in active production. The substitute part TG.30.8113 is currently active and available in production quantities (9958 units in stock).

Selection of TG.30.8113 as a substitute is based on:

• Frequency Coverage Alignment: The antenna's frequency range (700MHz ~ 2.8GHz) encompasses all required bands for the original modem (800MHz, 900MHz, 1.9GHz, 2.1GHz)
• RF Standard Support: TG.30.8113 supports GSM and CDMA standards, which are foundational to EDGE and GPRS protocol operation
• Environmental Compliance: Both components share MSL 1 classification, indicating equivalent moisture handling requirements
• Regulatory Compliance: TG.30.8113 is RoHS3 compliant and REACH unaffected, meeting current environmental standards

Integration of TG.30.8113 requires interface adaptation from USB (original modem) to SMA Male connector (antenna), necessitating appropriate RF coupling and impedance matching in the system design.

Frequently Asked Questions (FAQ)

Q: Why is TG.30.8113 listed as a substitute for a modem component?

A: The NL-S-4GT-VR is a complete modem kit requiring RF antenna integration. TG.30.8113 provides the multi-band antenna front-end necessary to support the same cellular frequency bands and RF standards. System redesign may require additional transceiver or modem components depending on application requirements.

Q: Are the frequency bands fully compatible?

A: TG.30.8113 covers all required frequency bands (800MHz, 900MHz, 1.9GHz, 2.1GHz) within its specified range of 700MHz ~ 2.8GHz. The antenna supports GSM and CDMA standards, which are the underlying technologies for EDGE and GPRS protocols.

Q: What interface changes are required?

A: The original NL-S-4GT-VR uses USB interface, while TG.30.8113 uses SMA Male connector termination. System integration requires appropriate RF coupling components and connector adaptation.

Q: Are both components suitable for the same environmental conditions?

A: Both components share Moisture Sensitivity Level 1 (Unlimited), indicating equivalent environmental handling. TG.30.8113 additionally provides IP67 ingress protection, offering enhanced environmental robustness.

Q: Is TG.30.8113 available for immediate procurement?

A: Yes. TG.30.8113 is classified as active product status with 9958 units in stock, ensuring availability for production and development applications.
