MAF94006 Equivalent & Substitute Parts Reference

Part Overview

The MAF94006 is a dual-band RF antenna manufactured by TE Connectivity Laird, designed for Bluetooth and WLAN applications operating across 2.4GHz and 5.5GHz frequency bands. This component features a whip/tilt antenna configuration with U.FL (UMCC) and IPEX MHF1 snap-in termination options, delivering 2.5dBi and 5.2dBi gain across its respective bands.

The MAF94006 carries an Obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or field replacement requirements for systems utilizing this antenna.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAF94006 is determined by the following critical parameters:

Frequency Compatibility: The substitute must operate across the 2.4GHz band (2.4GHz ~ 2.5GHz) as a minimum requirement. The 5.5GHz band operation (4.9GHz ~ 6GHz) represents the secondary band; substitutes operating at 5.8GHz fall within the acceptable SHF range for WLAN applications.

Antenna Configuration: The substitute must maintain whip/tilt antenna geometry to ensure mechanical and electrical performance equivalence in the target application.

Dual-Band Operation: The substitute must support two distinct frequency bands to match the multi-band capability of the MAF94006.

Termination Type: While the MAF94006 uses U.FL (UMCC) and IPEX MHF1 snap-in connectors, substitutes with alternative termination types (such as RP-SMA Male) may be considered if the application permits connector adaptation or if the substitute is integrated into a compatible module.

Gain Performance: Substitute gain values must fall within comparable ranges across both bands to maintain system link budget and performance specifications.

RF Standards Compliance: Substitutes must support Bluetooth and/or WiFi standards applicable to the target system.

The BB-ACH2-DBAT-DP003 meets these substitution criteria through dual-band operation (2.4GHz and 5.8GHz), whip/tilt configuration, comparable gain performance (3.8dBi and 5.5dBi), and active product status with current availability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MAF94006 is classified as Obsolete, making the BB-ACH2-DBAT-DP003 a necessary alternative for ongoing supply requirements. The substitute maintains Active product status with confirmed inventory availability (1065 pieces in stock).

Compliance and Certification: The BB-ACH2-DBAT-DP003 carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. These certifications support deployment in applications subject to modern regulatory frameworks.

Frequency Band Alignment: Both parts operate across the 2.4GHz ~ 2.5GHz band with full compatibility. The secondary band differs slightly (MAF94006: 4.9GHz ~ 6GHz; BB-ACH2-DBAT-DP003: 4.9GHz ~ 5.8GHz). For WLAN-only applications, the 5.8GHz upper limit of the substitute is sufficient. For Bluetooth-only applications, the 2.4GHz band provides complete coverage.

Gain Performance: The BB-ACH2-DBAT-DP003 delivers higher gain across both bands (3.8dBi at 2.4GHz versus 2.5dBi; 5.5dBi at 5.8GHz versus 5.2dBi). This performance improvement enhances link budget and system sensitivity.

Mechanical Integration: The substitute features a taller profile (174.00mm versus 124.46mm) and uses RP-SMA Male termination instead of U.FL/IPEX MHF1 snap-in connectors. Applications must accommodate these dimensional and connector differences through mechanical redesign or adapter solutions.

Application Scope: The BB-ACH2-DBAT-DP003 is specified for WLAN applications. Systems requiring Bluetooth functionality must verify compatibility through dual-band operation at 2.4GHz, as the substitute does not explicitly list Bluetooth in its application field.

Frequently Asked Questions (FAQ)

Q: Can the BB-ACH2-DBAT-DP003 directly replace the MAF94006 without modification?

A: Direct replacement requires mechanical and electrical adaptation. The substitute uses RP-SMA Male termination instead of U.FL (UMCC) and IPEX MHF1 snap-in connectors. The increased height (174.00mm versus 124.46mm) may require enclosure or mounting redesign. Connector adapters or cable assemblies may be necessary depending on the target application's PCB layout and connector infrastructure.

Q: Are both parts suitable for Bluetooth applications?

A: The MAF94006 explicitly supports Bluetooth and WLAN applications. The BB-ACH2-DBAT-DP003 is specified for WLAN applications only. Both parts operate at 2.4GHz, which is the Bluetooth frequency band. However, the substitute's application field does not include Bluetooth certification. Verification with the system designer is required for Bluetooth-dependent applications.

Q: What is the frequency band difference between these two antennas?

A: The primary 2.4GHz band (2.4GHz ~ 2.5GHz) is identical. The secondary band differs: MAF94006 covers 4.9GHz ~ 6GHz, while BB-ACH2-DBAT-DP003 covers 4.9GHz ~ 5.8GHz. For standard WLAN operation (802.11a/n/ac), the 5.8GHz upper limit is sufficient. Applications requiring operation above 5.8GHz must retain the MAF94006 or identify alternative substitutes.

Q: How do the gain specifications compare?

A: The BB-ACH2-DBAT-DP003 provides higher gain at both bands: 3.8dBi (2.4GHz) versus 2.5dBi for the MAF94006, and 5.5dBi (5.8GHz) versus 5.2dBi for the MAF94006. Higher gain improves received signal strength and system sensitivity, benefiting link budget performance.

Q: What are the compliance differences?

A: The BB-ACH2-DBAT-DP003 carries ROHS3 Compliant and REACH Unaffected certifications. The MAF94006 compliance status is not specified in the provided data. For applications subject to RoHS or REACH regulations, the substitute meets current environmental requirements.

Q: Can I use an adapter to connect the BB-ACH2-DBAT-DP003 to a U.FL connector?

A: RP-SMA Male to U.FL (UMCC) or IPEX MHF1 adapters are commercially available. However, adapter use introduces additional insertion loss and potential impedance discontinuities. System performance must be validated after adapter integration, particularly for gain-sensitive applications.

Q: What is the inventory status for both parts?

A: The MAF94006 has 890 pieces in stock (Obsolete status). The BB-ACH2-DBAT-DP003 has 1065 pieces in stock (Active status). The substitute offers superior long-term availability due to its Active product classification.
