GNSS4GDPSM-W Equivalent & Substitute Parts

Part Overview

The GNSS4GDPSM-W is a multi-band dome RF antenna manufactured by PCTEL, Inc., designed for GNSS, GPS, GLONASS, and LTE applications. This antenna operates across three frequency bands (698MHz–960MHz, 1.575GHz–1.61GHz, 1.71GHz–2.7GHz) with a 5-meter cable assembly and SMA male connector termination. The product is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the GNSS4GDPSM-W is determined by the following critical parameters:

Frequency Coverage: The substitute must support the primary frequency bands (698MHz–960MHz, 1.71GHz–2.7GHz) required for cellular and navigation applications.
Antenna Type: Dome configuration is preferred for form factor compatibility.
Termination Type: SMA Male connector is required for direct interface compatibility.
Ingress Protection: IP67 rating ensures environmental sealing equivalent to the original design.
Cable Assembly: 5-meter cable with appropriate connector types.
Gain Characteristics: Gain values must be within acceptable operational ranges for the target applications.
Compliance: RoHS3 compliance is mandatory for regulatory alignment.

Two substitute parts are identified based on these criteria:

710641 (PCTEL, Inc.): Active product with reduced band count (2 bands) but maintains core frequency coverage and electrical specifications.
GLLPDLTE-W (PCTEL, Inc.): Active product with extended multi-band coverage (12 bands) and enhanced frequency range, offering broader application support.

Engineering Selection Recommendations

710641 is the direct functional equivalent for applications requiring dome antenna form factor with identical frequency band coverage and electrical performance. This part maintains active product status and is recommended for direct replacement in systems where the original GNSS4GDPSM-W specifications are strictly required.

GLLPDLTE-W is suitable for applications requiring extended frequency coverage beyond the original specification. This part operates as an active product with ROHS3 compliance and provides multi-band support across 2G, 3G, 5G, Bluetooth, Cellular, GNSS, GPS, LTE, and Wi-Fi standards. The module antenna type and compact height (34.00mm) offer space-constrained installation advantages. Gain characteristics differ (3dBi vs. -8.85dBi/-10.97dBi), requiring system-level performance validation.

Selection between these substitutes depends on whether the application requires strict electrical parameter matching (710641) or extended frequency coverage capability (GLLPDLTE-W).

Frequently Asked Questions (FAQ)

Q: Can 710641 be used as a direct replacement for GNSS4GDPSM-W? A: Yes. The 710641 maintains identical frequency band coverage (698MHz–960MHz, 1.71GHz–2.7GHz), matching gain values (-8.85dBi, -10.97dBi), VSWR (2), SMA Male termination, 5-meter cable assembly, IP67 ingress protection, and identical physical height (40.00mm). This part is the functional equivalent.

Q: What are the key differences between 710641 and GLLPDLTE-W? A: The 710641 is a dome antenna with 2 frequency bands matching the original specification. The GLLPDLTE-W is a module antenna with 12 frequency bands, extended coverage (617MHz–5.95GHz), higher gain (3dBi), and compact height (34.00mm). The GLLPDLTE-W supports additional wireless standards (2G, 3G, 5G, Bluetooth, Wi-Fi) beyond the original GNSS/LTE scope.

Q: Is cable length specified for GLLPDLTE-W? A: Cable length is not provided in the available technical data for GLLPDLTE-W. Verification with PCTEL, Inc. is required if 5-meter cable assembly is a system requirement.

Q: Are all substitute parts RoHS3 compliant? A: GNSS4GDPSM-W and GLLPDLTE-W are confirmed ROHS3 compliant. RoHS status for 710641 is not specified in the available data.

Q: What is the physical form factor difference? A: GNSS4GDPSM-W and 710641 are dome antennas (40.00mm height). GLLPDLTE-W is a module antenna with reduced height (34.00mm), suitable for space-constrained applications.
