4GDPSM-W Equivalent & Substitute Parts

Part Overview

The 4GDPSM-W is a multi-band dome RF antenna manufactured by PCTEL, Inc., designed for cellular and navigation applications. This antenna operates across three frequency bands (698MHz ~ 960MHz, 1.575GHz ~ 1.61GHz, 1.71GHz ~ 2.7GHz) and supports GLONASS, GNSS, GPS, and LTE protocols. The unit features a 5-meter RG-174/U cable with SMA Male connector termination and IP67 ingress protection. The product is currently listed as Obsolete, necessitating identification of active equivalent alternatives for continued system integration and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4GDPSM-W is determined by the following critical parameters:

• Antenna Type: Must be Dome configuration
• Frequency Coverage: Must support overlapping frequency ranges within 698MHz ~ 960MHz and 1.71GHz ~ 2.7GHz bands
• Termination Type: Must feature SMA Male connector
• Cable Configuration: Must include 5-meter cable assembly
• Ingress Protection: Must maintain IP67 rating
• Physical Dimensions: Height must not exceed 1.575" (40.00mm)
• VSWR Performance: Must meet or exceed VSWR of 2
• Mounting Interface: Connector Mount or Stud mounting acceptable

The substitute part 710682 meets these criteria while offering Active product status, making it a valid alternative for applications requiring multi-band cellular and navigation antenna functionality.

Parameter Comparison

Engineering Selection Recommendations

The 710682 substitute part is recommended for applications where GNSS (1.575GHz ~ 1.61GHz) band coverage is not required. Both parts maintain identical mechanical form factors, connector interfaces, and environmental protection ratings. The 710682 offers the advantage of Active product status, ensuring continued availability and manufacturing support from PCTEL, Inc.

For applications requiring full three-band coverage including GNSS frequencies, alternative parts within the 4GDPSM series should be evaluated. The substitute maintains RoHS3 compliance and equivalent performance characteristics across supported frequency bands.

Frequently Asked Questions (FAQ)

Q: Can the 710682 directly replace the 4GDPSM-W in all applications?

A: The 710682 is compatible with applications using LTE, GPS, and GLONASS protocols. However, it does not cover the GNSS band (1.575GHz ~ 1.61GHz) present in the 4GDPSM-W. Verify your system requirements before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 4GDPSM-W and 710682 share identical maximum height specifications of 1.575" (40.00mm) and mounting footprints, allowing direct mechanical interchange.

Q: What is the difference in connector mounting between these parts?

A: The 4GDPSM-W uses Connector Mount termination, while the 710682 uses SMA Male Stud mounting. Both employ SMA Male connectors and are compatible with standard SMA receptacles.

Q: Are both parts RoHS compliant?

A: The 4GDPSM-W is RoHS3 compliant. Compliance information for the 710682 should be verified with PCTEL, Inc. documentation.

Q: What is the cable configuration for both parts?

A: Both parts include 5-meter RG-174/U coaxial cable assemblies with SMA Male connectors, providing identical cable specifications and routing flexibility.
