Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAF94148 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency Range: 2.4GHz ~ 2.5GHz
• Antenna Type: PCB Trace
• Gain: 2dBi
• Termination: U.FL (UMCC), IPEX MHF1
• Mounting Type: Surface Mount
• Height (Max): 0.032" (0.81mm)
• RF Family/Standard: Bluetooth, WiFi
• Moisture Sensitivity Level: 1 (Unlimited)

The MAF94045 qualifies as a direct substitute based on complete alignment with all mandatory parameters. The primary distinction between these parts is cable length (47mm for MAF94148 versus 100mm for MAF94045) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

MAF94045 as Primary Substitute:

The MAF94045 is the direct functional equivalent to the obsolete MAF94148. Both components share identical electrical and mechanical specifications across all critical RF and physical parameters. The MAF94045 carries active product status with RoHS compliance and REACH unaffected designation, providing superior supply chain stability and regulatory alignment compared to the obsolete MAF94148.

Cable Length Consideration:

The MAF94045 features a 100mm cable assembly compared to the 47mm cable on the MAF94148. This difference must be evaluated within the context of the target application's physical layout and routing requirements. The extended cable length provides additional routing flexibility but requires verification of available board space and cable management constraints.

Compliance and Availability:

The MAF94045 is currently in active production with 1241 pieces in stock inventory, compared to 894 pieces for the obsolete MAF94148. The MAF94045 maintains RoHS compliance and REACH unaffected status, supporting modern regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the MAF94045 directly replace the MAF94148 in existing designs?

A: The MAF94045 is electrically and mechanically equivalent to the MAF94148 across all RF performance parameters (frequency range, gain, termination, and antenna type). The primary design consideration is the cable length difference (100mm versus 47mm). Designs must accommodate the longer cable routing or implement cable management solutions. No circuit modifications are required.

Q: What is the significance of the cable length difference?

A: The MAF94045 provides a 53mm longer cable assembly than the MAF94148. This extended length offers greater routing flexibility in applications with distributed component placement but requires verification that the target PCB layout can accommodate the additional cable length without signal integrity degradation or mechanical stress.

Q: Why is the MAF94148 listed as obsolete?

A: The MAF94148 carries obsolete product status, indicating that the manufacturer has discontinued active production and support. The MAF94045 represents the current active equivalent within the NanoBlue series, ensuring access to ongoing manufacturing support and supply chain continuity.

Q: Are there compliance differences between these parts?

A: The MAF94045 explicitly carries RoHS compliance and REACH unaffected designations. Both components share identical MSL ratings (1 - Unlimited) and ECCN classifications. The MAF94045 provides documented compliance certifications suitable for modern procurement requirements.

Q: What packaging formats are available?

A: The MAF94148 is supplied in standard packaging configuration. The MAF94045 is available in bulk packaging, which may affect procurement quantities and logistics considerations for production environments.
