TW5341 Equivalent & Substitute Parts

Part Overview

The TW5341 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 TW5341 is classified as obsolete and no longer in active production, necessitating identification of functionally equivalent substitute components for ongoing system integration and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TW5341 is based on alignment of the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Tallysman Wireless Inc. (same manufacturer ensures design compatibility and performance consistency)
• Antenna Type: Dome configuration (maintains form factor and radiation pattern characteristics)
• Applications: GLONASS and GPS support (preserves dual-constellation navigation capability)
• RF Family/Standard: Navigation (ensures frequency band alignment for SBAS GPS L1 and GLONASS G1)
• Termination: RJ45 connector (maintains interface compatibility with existing cabling and equipment)
• RoHS Status: ROHS3 Compliant (ensures regulatory compliance equivalence)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (confirms equivalent environmental handling requirements)

The TW5351 satisfies all primary substitution criteria as a manufacturer-recommended equivalent from Tallysman Wireless Inc., with active product status and full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TW5351 is the manufacturer-recommended substitute for the obsolete TW5341. Both components share identical functional descriptions (SMART ANT SBAS GPS L1 GLONASS G1) and maintain equivalent electrical and mechanical specifications across all provided parameters. The TW5351 carries active product status, ensuring long-term availability and continued manufacturer support. Both components maintain ROHS3 compliance and MSL 1 (Unlimited) ratings, confirming equivalent environmental and regulatory standing. Selection of the TW5351 for new designs and system replacements eliminates obsolescence risk while preserving full functional compatibility with existing TW5341 installations.

Frequently Asked Questions (FAQ)

Q: Can the TW5351 directly replace the TW5341 in existing installations?

A: Yes. Both components share identical functional specifications, antenna type (dome), termination (RJ45), and application support (GLONASS and GPS navigation). The TW5351 is the manufacturer-recommended equivalent.

Q: What is the primary reason for substitution?

A: The TW5341 is classified as obsolete and no longer in active production. The TW5351 provides equivalent functionality with active product status and assured long-term availability.

Q: Are there differences in regulatory compliance between the two parts?

A: No. Both the TW5341 and TW5351 maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL 1 - Unlimited) ratings.

Q: Does the TW5351 maintain the same physical form factor?

A: Both components are dome-type antennas with identical antenna type classification. The TW5341 specifies a maximum height of 0.827" (21.00mm). Physical form factor compatibility should be confirmed through detailed mechanical drawings if space constraints are critical.

Q: Is the RJ45 termination identical on both parts?

A: Yes. Both the TW5341 and TW5351 utilize RJ45 termination, ensuring connector compatibility with existing cabling and interface equipment.

Q: What is the inventory status for each part?

A: The TW5341 has 832 pieces available as new original stock. The TW5351 has 1052 pieces available as new original stock, providing greater availability for new procurements.
