MAF94190 Equivalent & Substitute Parts Reference

Part Overview

The MAF94190 is a 2.45GHz PCB trace RF antenna manufactured by TE Connectivity Laird, designed for surface mount applications in the 2.4GHz to 2.5GHz frequency band. This component features a U.FL (UMCC) IPEX MHF1 connector interface and is optimized for compact PCB integration.

The MAF94190 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this antenna type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAF94190 is determined by the following critical parameters:

Primary Substitution Criteria:

• Frequency Range: 2.4GHz ~ 2.5GHz (mandatory overlap)
• Frequency Group: UHF (2GHz ~ 3GHz)
• Termination Type: U.FL (UMCC) connector family
• Manufacturer: TE Connectivity Laird (same manufacturer ecosystem)

Secondary Compatibility Factors:

• Number of Bands: Single-band operation
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The substitute part 0600-00057 meets the primary substitution criteria through identical frequency range coverage (2.4GHz ~ 2.5GHz), compatible U.FL (UMCC) termination (IPEX MHF4 variant), and same manufacturer origin. Both parts operate within the UHF frequency group and share MSL 1 classification.

The primary difference is antenna form factor: MAF94190 uses PCB trace construction for integrated board-level implementation, while 0600-00057 employs whip antenna construction with connector mount configuration. This distinction affects physical integration approach but does not preclude functional substitution in frequency-dependent applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MAF94190 is obsolete, while 0600-00057 maintains active product status with TE Connectivity Laird. Active status ensures ongoing manufacturer support, availability, and compliance maintenance.

Compliance and Certification: The 0600-00057 substitute carries explicit RoHS Compliance certification. The MAF94190 RoHS status is not specified in available documentation. For applications requiring regulatory compliance verification, the 0600-00057 provides documented RoHS compliance.

Frequency Compatibility: Both parts operate within the identical 2.4GHz ~ 2.5GHz frequency range, satisfying frequency-dependent application requirements. The MAF94190 center frequency is 2.45GHz; the 0600-00057 center frequency is 2.4GHz. Both values fall within the common operating band.

Connector Interface: Both parts utilize U.FL (UMCC) termination from the IPEX connector family. The MAF94190 specifies IPEX MHF1; the 0600-00057 specifies IPEX MHF4. These are distinct connector variants within the same family and require mechanical verification for physical compatibility in existing connector footprints.

Form Factor and Integration: The MAF94190 PCB trace antenna integrates directly into PCB layout. The 0600-00057 whip antenna requires external connector mounting. Design integration approach differs significantly; physical space allocation and PCB layout must be re-evaluated for substitution.

Frequently Asked Questions (FAQ)

Q: Can 0600-00057 directly replace MAF94190 in existing designs?

A: Functional frequency compatibility exists (both operate 2.4GHz ~ 2.5GHz). However, physical integration differs fundamentally. MAF94190 is a PCB trace antenna requiring board-level integration; 0600-00057 is a connector-mount whip antenna. Mechanical redesign of antenna mounting and connector interface is required. Connector compatibility between IPEX MHF1 and IPEX MHF4 variants must be verified against specific connector footprints.

Q: What are the key parameters determining substitution eligibility?

A: Substitution is determined by: (1) Frequency range overlap (2.4GHz ~ 2.5GHz required), (2) U.FL (UMCC) termination family compatibility, (3) Single-band operation, (4) MSL 1 classification. The antenna form factor (PCB trace vs. whip) affects physical implementation but does not preclude frequency-based substitution.

Q: Does 0600-00057 provide performance specifications that MAF94190 lacks?

A: Yes. The 0600-00057 includes documented gain (2dBi), VSWR (2), and return loss (-10dB) specifications. The MAF94190 does not provide these performance metrics in available documentation. Applications requiring specific gain or impedance matching characteristics should reference the 0600-00057 specifications as baseline performance expectations.

Q: What compliance differences exist between these parts?

A: The 0600-00057 carries explicit RoHS Compliance certification and active product status. The MAF94190 is obsolete with unspecified RoHS status. For applications subject to RoHS regulatory requirements, the 0600-00057 provides documented compliance assurance.

Q: Are IPEX MHF1 and IPEX MHF4 connectors mechanically compatible?

A: Both are U.FL (UMCC) connector variants within the IPEX family but represent distinct connector types. Mechanical compatibility depends on specific connector footprint design. Direct physical substitution without connector interface verification is not recommended. Consult connector specification sheets for dimensional compatibility.

Q: What inventory status should influence substitution decisions?

A: MAF94190 inventory is listed as 838 pieces in stock (new original). 0600-00057 inventory is 671 pieces in stock (new original). Both parts maintain current inventory availability. Long-term supply assurance favors 0600-00057 due to active product status.
