TW5343 Equivalent & Substitute Parts

Part Overview

The TW5343 is a GLONASS and GPS dome RF antenna manufactured by Tallysman Wireless Inc., designed for navigation applications with mast mount and through-hole installation. The antenna features a 5-meter cable terminated with RJ45 connector and operates across SBAS GPS L1 and GLONASS G1 frequency bands. The TW5343 is classified as obsolete and no longer in active production. Identification of equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring GLONASS/GPS navigation antenna functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TW5343 is based on functional equivalence across the following critical parameters:

Primary Substitution Criteria:

• Antenna type classification (Dome)
• Navigation RF family and supported frequency bands (GLONASS G1, GPS L1, SBAS)
• Connector termination standard (RJ45)
• Mounting configuration (Mast Mount, Through Hole)
• Physical height envelope (45.00mm maximum)
• Environmental protection rating (IP69K)
• Regulatory compliance (ROHS3 Compliant)
• Moisture sensitivity classification (MSL 1)

The TW5353 satisfies these substitution criteria as an active production alternative within the Tallysman Wireless Inc. product portfolio, maintaining functional compatibility with applications originally designed for the TW5343.

Parameter Comparison

Engineering Selection Recommendations

The TW5353 is the manufacturer-recommended substitute for the obsolete TW5343. Both components share identical functional descriptions and maintain equivalent ROHS3 compliance and MSL classification. The TW5353 is currently in active production status with confirmed inventory availability (1082 pieces), whereas the TW5343 is obsolete with limited remaining stock (633 pieces).

Selection of the TW5353 for new designs or replacement applications is supported by:

• Identical RF antenna functionality across GLONASS G1 and GPS L1 frequency bands
• Equivalent dome antenna architecture
• Matching regulatory compliance certifications (ROHS3 Compliant, MSL 1)
• Active manufacturer support and ongoing production
• Confirmed availability through authorized distribution channels

Frequently Asked Questions (FAQ)

Q: Can the TW5353 directly replace the TW5343 in existing installations?

A: The TW5353 is the manufacturer-recommended substitute and shares identical functional specifications for GLONASS/GPS navigation antenna applications. Compatibility is determined by the mechanical mounting interface, connector type (RJ45), and cable length requirements of the original installation.

Q: What is the primary reason for substituting the TW5343?

A: The TW5343 is classified as obsolete and no longer in active production. The TW5353 provides functional equivalence as an active production alternative from the same manufacturer.

Q: Are there differences in antenna performance between the TW5343 and TW5353?

A: Both components are described identically as SMART ANT SBAS GPS L1 GLONASS G1 dome antennas. Performance parameters not provided in the specification data (such as gain, VSWR, or return loss) cannot be compared based on available documentation.

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

A: Substitution is based on antenna type (dome), supported navigation bands (GLONASS G1, GPS L1, SBAS), connector standard (RJ45), mounting configuration (mast mount, through hole), environmental protection (IP69K), and regulatory compliance (ROHS3, MSL 1).

Q: Is the TW5353 available in the same packaging and cable configuration as the TW5343?

A: The TW5353 is confirmed as an active production part with 1082 pieces in stock. Specific packaging and cable configuration details for the TW5353 should be verified against the complete technical datasheet for the substitute part number.

Q: What is the inventory status of each part?

A: The TW5343 (obsolete) has 633 pieces available. The TW5353 (active) has 1082 pieces available through current distribution channels.
