SAF25054 Equivalent & Substitute Parts

Part Overview

The SAF25054 is an RF antenna dipole with right-angle configuration manufactured by TE Connectivity Laird. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and component procurement. The SAF25054 serves as a dipole antenna operating at 140 FL frequency specification, designed for RF applications requiring right-angle mounting geometry.

Due to its obsolete status, sourcing direct replacements requires evaluation of functionally equivalent alternatives that maintain compatibility with the original application requirements while meeting current availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SAF25054 is based on the following critical parameters:

Antenna Configuration: Right-angle mounting geometry is maintained as a primary substitution criterion. The SAF25054 dipole configuration requires equivalent antenna types that support right-angle physical orientation.

Connector Interface: Termination type compatibility determines mechanical and electrical fit within the host system. The substitute part must provide equivalent connector mounting capability.

Frequency Operation: While the SAF25054 operates at 140 FL specification, substitute parts must operate within frequency bands compatible with the original application requirements.

Regulatory Compliance: MSL rating of 1 (Unlimited) establishes baseline moisture handling requirements. Substitute parts must meet or exceed this specification.

Product Availability: Active product status is preferred for long-term supply chain reliability and technical support continuity.

The identified substitute part W24-RSMA-M from Inventek Systems meets these substitution criteria through equivalent right-angle antenna configuration, active product status, and established regulatory compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SAF25054 is classified as obsolete. The W24-RSMA-M substitute maintains active product status, ensuring continued manufacturer support, technical documentation availability, and supply chain reliability for future procurement cycles.

Compliance and Certification: Both parts maintain MSL 1 (Unlimited) rating, indicating equivalent moisture handling capability. The W24-RSMA-M carries RoHS Compliant and REACH Unaffected certifications, meeting current regulatory requirements. The SAF25054 ECCN classification (5A991G) differs from the substitute (EAR99), requiring export compliance review for specific applications.

Regulatory Classification: HTSUS codes differ between parts (8529.10.9100 vs. 8517.71.0000), reflecting different product categorization. This distinction may impact tariff treatment and import/export documentation requirements.

Inventory and Supply: Both components are currently in stock with substantial quantities. The W24-RSMA-M provides superior long-term availability assurance due to active manufacturing status.

Application-Specific Verification: Frequency band compatibility (140 FL vs. 2.4GHz ~ 2.5GHz) requires confirmation that the substitute operates within the original application's frequency requirements. Connector interface compatibility (SMA Male termination) must be verified against the host system's connector specification.

Frequently Asked Questions (FAQ)

Q: Why is the SAF25054 being discontinued?

A: The SAF25054 is classified as obsolete by the manufacturer. Obsolete status indicates the manufacturer has ceased production and support. Identifying active substitute parts ensures continued system support and component availability.

Q: What makes W24-RSMA-M a suitable substitute for SAF25054?

A: Both parts share right-angle antenna configuration, equivalent MSL ratings, and current stock availability. The W24-RSMA-M provides defined electrical specifications (VSWR, return loss, gain) and active product status, supporting long-term procurement reliability.

Q: Are the frequency specifications compatible?

A: The SAF25054 operates at 140 FL specification, while W24-RSMA-M operates at 2.4GHz ~ 2.5GHz. Frequency compatibility depends on the original application's operating band. Application-specific frequency requirements must be confirmed before substitution.

Q: What is the difference between the antenna types?

A: SAF25054 is a dipole antenna; W24-RSMA-M is a whip antenna. Both support right-angle mounting. Dipole and whip antennas have different radiation patterns and gain characteristics. The specific antenna type requirement depends on the application's RF performance needs.

Q: Does the connector type affect substitution?

A: Yes. The W24-RSMA-M provides SMA Male termination. The host system connector must be compatible with SMA Male interface. If the original SAF25054 uses a different connector type, mechanical and electrical adaptation may be required.

Q: What is the significance of the different ECCN classifications?

A: SAF25054 (5A991G) and W24-RSMA-M (EAR99) have different export control classifications. This affects export licensing requirements and international shipping restrictions. Compliance review is necessary for applications involving international distribution.

Q: Can I use W24-RSMA-M as a direct drop-in replacement?

A: Direct replacement compatibility depends on connector type, frequency band, and physical mounting geometry of the original application. Mechanical fit (right-angle configuration is present in both), electrical interface (SMA Male connector), and frequency band (2.4GHz ~ 2.5GHz) must all be verified against original system specifications.

Q: What packaging differences exist between these parts?

A: SAF25054 uses standard packaging; W24-RSMA-M uses bulk packaging. Packaging format does not affect component functionality but may impact handling, storage, and quantity ordering requirements.

Q: Are there compliance certifications I should verify?

A: W24-RSMA-M carries RoHS Compliant and REACH Unaffected certifications. If the original application requires specific compliance certifications, verify that the substitute meets those requirements. SAF25054 compliance certifications should be confirmed with the manufacturer or original documentation.

Q: What is the maximum power rating for the substitute?

A: W24-RSMA-M is rated for 50 W maximum power. If the original application requires higher power handling, this specification must be confirmed as adequate for the intended use.
