Key Parameters

Substitute Part Grouping Explanation

Substitution of the WAN03RSP is determined by the following critical parameters that must align across candidate parts:

Primary Substitution Criteria:

• Frequency center band: 2.4GHz operation
• Frequency group: UHF (2GHz ~ 3GHz)
• Termination type: RP-SMA Male connector
• Mounting method: Adhesive
• Number of bands: Single band operation
• Physical form factor: Flat antenna configuration

Secondary Compatibility Parameters:

• Mechanical height compatibility: Maximum 0.310" (7.87mm)
• Environmental compliance: RoHS compliance status
• Moisture sensitivity: MSL 1 rating

The WSA.2400.A.101151 manufactured by Taoglas Limited satisfies all primary substitution criteria. This part operates at 2.4GHz within the UHF frequency group, utilizes RP-SMA male termination, employs adhesive mounting, and maintains single-band operation. Physical dimensions remain within acceptable tolerance ranges for form factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

WAN03RSP (Honeywell Sensing and Productivity Solutions): The WAN03RSP is classified as obsolete. While RoHS compliant with MSL 1 rating, this part is no longer in active production. Selection of this part is limited to legacy system maintenance where existing inventory is available.

WSA.2400.A.101151 (Taoglas Limited) - Recommended Substitute: The WSA.2400.A.101151 is the designated substitute for the WAN03RSP. This part is currently active in production status, ensuring long-term availability and supply chain continuity. It maintains RoHS3 compliance, exceeding the original RoHS requirement, and carries REACH unaffected status. The part operates within the identical 2.4GHz frequency band with RP-SMA male termination and adhesive mounting. Physical dimensions are compatible with the original form factor. The WSA.2400.A.101151 is suitable for new designs and ongoing system support applications requiring 2.4GHz adhesive-mounted antenna solutions.

Frequently Asked Questions (FAQ)

Q: Can the WSA.2400.A.101151 directly replace the WAN03RSP in existing designs?

A: The WSA.2400.A.101151 is electrically and mechanically compatible with the WAN03RSP for applications requiring 2.4GHz adhesive-mounted RP-SMA male antennas. Both parts operate at identical center frequency, utilize the same connector type, and employ adhesive mounting. Physical dimensions are within compatible ranges. The substitute part is suitable for direct replacement in systems designed for the WAN03RSP.

Q: What is the difference in antenna type between the two parts?

A: The WAN03RSP is specified as a flat patch antenna, while the WSA.2400.A.101151 is a flat bar antenna. Both are planar antenna configurations suitable for 2.4GHz operation with adhesive mounting. The flat bar configuration of the substitute part maintains compatibility with the original flat patch design intent for low-profile, surface-mounted applications.

Q: How do the gain specifications differ?

A: The WAN03RSP specifies 3dBi gain, while the WSA.2400.A.101151 specifies -2.41dBi gain. Both parts operate at 2.4GHz with RP-SMA male termination. Gain differences reflect design variations between manufacturers but do not preclude functional substitution for applications where the 2.4GHz frequency band and connector type are primary requirements.

Q: What compliance certifications apply to the substitute part?

A: The WSA.2400.A.101151 carries ROHS3 compliance, which exceeds the RoHS compliance of the original WAN03RSP. The substitute part is REACH unaffected. Both parts maintain MSL 1 (unlimited moisture sensitivity level) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Is the WSA.2400.A.101151 available in the same packaging as the WAN03RSP?

A: The WAN03RSP packaging is specified as dash (-), while the WSA.2400.A.101151 is supplied in bag packaging. Both parts are available in new original condition with current inventory. Packaging differences do not affect electrical or mechanical compatibility for component integration.

Q: Why is the WAN03RSP classified as obsolete?

A: The WAN03RSP is no longer in active production by Honeywell Sensing and Productivity Solutions. The obsolete status indicates that new production runs are not available. The WSA.2400.A.101151 is the active substitute part for ongoing system support and new design implementations requiring equivalent 2.4GHz adhesive-mounted antenna functionality.
