Equivalent & Substitute Parts for CA.25

Part Overview

The CA.25 is a dual-band chip RF antenna manufactured by Taoglas Limited, designed for 2.4GHz and 5.5GHz applications including Bluetooth, WLAN, and Zigbee™ connectivity. This surface mount antenna operates across 2.4GHz ~ 2.5GHz and 5.15GHz ~ 5.85GHz frequency bands with 3.3dBi gain. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CA.25 is determined by the following critical parameters:

• Dual-band operation at 2.4GHz and 5.5GHz center frequencies
• Chip antenna form factor with surface mount configuration
• Frequency range coverage: 2.4GHz ~ 2.5GHz and 5.15GHz ~ 5.85GHz bands
• Surface mount height compatibility (maximum 0.022")
• ROHS3 compliance and MSL 1 rating for manufacturing compatibility

The substitute part 2450AD14A5500001T from Johanson Technology Inc. meets these core substitution criteria through matching dual-band chip antenna architecture, overlapping frequency coverage, surface mount deployment, and equivalent environmental compliance ratings.

Parameter Comparison

Engineering Selection Recommendations

The 2450AD14A5500001T serves as a functional equivalent for the obsolete CA.25 based on the following engineering criteria:

Both parts maintain ROHS3 compliance and MSL 1 ratings, ensuring compatibility with standard manufacturing processes and storage conditions. The substitute part is currently in active production status, providing supply chain continuity for applications requiring dual-band 2.4GHz/5.5GHz chip antenna functionality.

The 2450AD14A5500001T exhibits higher gain (4dBi versus 3.3dBi) and reduced maximum height (0.016" versus 0.022"), offering potential advantages in compact PCB layouts and link budget performance. The substitute part's 2.4GHz frequency range extends to 2.48GHz, providing slightly narrower coverage in the lower band compared to the CA.25's 2.5GHz upper limit.

Selection between these parts should be based on specific application frequency requirements, available PCB height constraints, and gain performance needs within the target system design.

Frequently Asked Questions (FAQ)

Q: Can the 2450AD14A5500001T directly replace the CA.25 in existing designs?

A: The 2450AD14A5500001T is mechanically and electrically compatible for applications operating within the 2.4GHz ~ 2.48GHz and 5.15GHz ~ 5.85GHz bands. The reduced maximum height (0.016" versus 0.022") may require PCB layout verification. Higher gain (4dBi versus 3.3dBi) may affect impedance matching and require tuning adjustments.

Q: What are the key differences in frequency coverage?

A: The CA.25 covers 2.4GHz ~ 2.5GHz in the lower band, while the 2450AD14A5500001T covers 2.4GHz ~ 2.48GHz. Both cover 5.15GHz ~ 5.85GHz identically. Applications requiring operation above 2.48GHz in the 2.4GHz band should verify compatibility.

Q: Are packaging formats compatible?

A: The CA.25 uses standard surface mount packaging. The 2450AD14A5500001T is supplied in Tape & Reel (TR) format. Both are surface mount chip antennas with compatible termination methods for PCB assembly.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant with MSL 1 ratings and REACH unaffected status. Manufacturing and storage requirements are equivalent.

Q: What RF standards does each part support?

A: The CA.25 supports 802.15.4, Bluetooth, and WiFi standards. The 2450AD14A5500001T is specified for WiFi applications. Verify Bluetooth and Zigbee™ compatibility requirements for your specific application.
