ACA-102-T RF Antenna Equivalent & Substitute Parts

Part Overview

The ACA-102-T is a 2.4GHz chip RF antenna manufactured by Abracon LLC, designed for Bluetooth and WLAN applications. This component operates in the UHF frequency band (2GHz–3GHz) with a center frequency of 2.4GHz and a frequency range of 2.4GHz–2.485GHz. The part features a solder termination and surface mount packaging with a maximum height of 0.039" (1.00mm).

The ACA-102-T is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this antenna.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACA-102-T is determined by the following critical parameters:

• Frequency Compatibility: Center frequency of 2.4GHz with overlapping or compatible frequency range within the 2.4GHz–2.485GHz band
• Antenna Type: Chip antenna configuration
• Termination Method: Solder termination
• Mounting Type: Surface mount technology
• RF Standards: Bluetooth and WiFi applications
• Electrical Performance: VSWR and gain values within acceptable operational margins
• Compliance: ROHS3 compliance and MSL rating of 1

The W3092 from Pulse Electronics meets these substitution criteria. It operates at the same 2.4GHz center frequency with a compatible frequency range (2.4GHz–2.483GHz), maintains chip antenna configuration with solder termination, and is surface mount compatible. Both parts are ROHS3 compliant with MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The W3092 (Pulse Electronics) is the manufacturer-recommended substitute for the ACA-102-T. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

The W3092 offers the advantage of active product status, providing assured long-term availability and supply chain continuity compared to the obsolete ACA-102-T. The W3092 features a lower profile (0.022" versus 0.039"), which may benefit space-constrained PCB layouts.

Electrical performance differences exist: the W3092 provides higher gain (0.8dBi versus 0.6dBi) and slightly higher VSWR (3 versus 2.6). The frequency range of the W3092 (2.4GHz–2.483GHz) is marginally narrower than the ACA-102-T (2.4GHz–2.485GHz), though both cover the standard Bluetooth and WiFi operating bands. These variations fall within typical antenna performance tolerances for 2.4GHz chip antenna applications.

Frequently Asked Questions (FAQ)

Q: Can the W3092 directly replace the ACA-102-T in existing designs?

A: Yes. Both parts share identical center frequency (2.4GHz), antenna type (chip), termination method (solder), and mounting type (surface mount). Frequency ranges overlap substantially, and both support Bluetooth and WiFi standards. The W3092's lower profile may require PCB layout verification in space-constrained applications.

Q: What are the key electrical differences between these parts?

A: The W3092 provides 0.2dBi higher gain (0.8dBi versus 0.6dBi) and has a VSWR of 3 compared to the ACA-102-T's 2.6. The W3092 frequency range (2.4GHz–2.483GHz) is 2MHz narrower at the upper band edge than the ACA-102-T (2.4GHz–2.485GHz). These differences are within normal performance variation for 2.4GHz chip antennas.

Q: Are there packaging or handling differences?

A: The W3092 is supplied in Tape & Reel (TR) packaging, while the ACA-102-T packaging format is not specified in available data. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Why is the ACA-102-T listed as obsolete?

A: The ACA-102-T is no longer in active production. The W3092 represents the current active alternative for 2.4GHz Bluetooth and WiFi chip antenna applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the ACA-102-T and W3092 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components.
