GRS.01.A.024KSSX1 Equivalent & Substitute Parts

Part Overview

The GRS.01.A.024KSSX1 is a 1.575GHz dome RF antenna with connector base mount, designed for multi-constellation satellite navigation applications including Beidou, Galileo, GLONASS, and GPS. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system design and procurement. Substitute parts must maintain functional compatibility across the specified frequency band and navigation standards while accommodating system-level integration requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GRS.01.A.024KSSX1 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Frequency coverage: Must include 1.575GHz center frequency or encompass it within the operating frequency range
• Antenna type: Dome configuration required for form factor and radiation pattern consistency
• RF family/standard: Navigation band operation (UHF 1GHz ~ 2GHz)
• Applications: Support for Beidou, Galileo, GLONASS, and GPS constellations
• Regulatory compliance: ROHS3 and REACH status alignment

Secondary Integration Considerations:

• Termination type compatibility with system RF interfaces
• Mounting methodology accommodation within mechanical envelope constraints
• Physical dimensions relative to installation space availability

The substitute part 33-2710-00-5000 (Tallysman Wireless Inc., Accutenna® series) meets primary compatibility criteria through multi-frequency coverage (1.561GHz, 1.575GHz, 1.602GHz) with frequency range 1.557GHz ~ 1.606GHz, dome antenna configuration, and full navigation constellation support. Both parts maintain equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 33-2710-00-5000 substitute part is suitable for applications requiring replacement of the obsolete GRS.01.A.024KSSX1 based on the following factors:

Regulatory and Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent environmental and regulatory standing for procurement and deployment.

Frequency Coverage Compatibility: The substitute part's frequency range (1.557GHz ~ 1.606GHz) encompasses the primary 1.575GHz center frequency of the original part, supporting all specified navigation constellations (Beidou, Galileo, GLONASS, GPS) without frequency band gaps.

Product Status Advantage: The substitute part maintains active product status, ensuring long-term availability, supply chain stability, and manufacturer support compared to the obsolete original part.

Integration Considerations: System designers must account for differences in termination type (SMA Male vs. generic connector), mounting methodology (magnetic/chassis mount vs. base mount), and physical dimensions (15.10mm vs. 178.00mm height). These differences require mechanical and electrical interface verification within the target application.

Frequently Asked Questions (FAQ)

Q: Can the 33-2710-00-5000 directly replace the GRS.01.A.024KSSX1 in existing designs?

A: Direct replacement requires verification of three integration points: RF termination compatibility (SMA Male connector interface), mechanical mounting accommodation (magnetic/chassis mount vs. base mount), and physical envelope constraints (15.10mm vs. 178.00mm height). Frequency coverage is compatible across all navigation bands.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by frequency coverage (must include or encompass 1.575GHz), antenna type (dome configuration), RF family (navigation standard), constellation support (Beidou, Galileo, GLONASS, GPS), and regulatory compliance (ROHS3, REACH status). Secondary factors include termination type, mounting method, and physical dimensions relative to system constraints.

Q: Why is the substitute part significantly smaller in height?

A: The GRS.01.A.024KSSX1 height specification (178.00mm) reflects the base mount connector assembly, while the 33-2710-00-5000 height (15.10mm) represents the dome antenna element only. The substitute part includes magnetic mounting and chassis mount options, which may alter the total system height depending on installation configuration.

Q: Are there performance differences between the parts?

A: The substitute part provides specified performance metrics (VSWR 1.5, Gain 4.75dBic, IP67 ingress protection) not documented for the original part. These represent additional capabilities rather than performance degradation. System performance validation is required for applications with specific gain or VSWR requirements.

Q: What is the inventory status for procurement planning?

A: The GRS.01.A.024KSSX1 has 971 pieces in stock (obsolete status). The 33-2710-00-5000 substitute has 879 pieces in stock with active product status, providing better long-term supply assurance for new designs and ongoing production.
