A30BN/6 RF Antenna Equivalent & Substitute Parts

Part Overview

The A30BN/6 is a 30MHz whip straight RF antenna with BN connector mount, manufactured by TE Connectivity Laird. This component is designed for VHF frequency applications operating at 30MHz with a maximum power rating of 50W and a VSWR of 1.5. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain system functionality and ensure continued component availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A30BN/6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency (Center/Band): 30MHz
• Frequency Group: VHF (f < 300MHz)
• Antenna Type: Whip, Straight
• Number of Bands: 1
• VSWR: 1.5
• Power - Max: 50 W
• Termination: BN connector
• Mounting Type: Connector Mount
• Moisture Sensitivity Level: 1 (Unlimited)

The A30BN qualifies as a direct substitute because it maintains identical electrical and mechanical specifications across all provided parameters. The primary distinction is product status: A30BN/6 is obsolete while A30BN is active, and physical height differs (6.000" versus 10.500"), which may affect mechanical integration in specific applications.

Engineering Selection Recommendations

The A30BN is the appropriate substitute for the obsolete A30BN/6 based on the following engineering criteria:

Electrical Equivalence: All RF performance parameters are identical, including frequency operation at 30MHz, VSWR of 1.5, and maximum power handling of 50W. Both components operate within the VHF frequency group and utilize identical BN connector termination.

Mechanical Compatibility: While the A30BN exhibits a greater physical height (10.500" versus 6.000"), both components employ identical connector mount attachment methods. Height difference must be evaluated against specific mechanical envelope constraints in the target application.

Product Status and Compliance: The A30BN is active and carries RoHS Compliant certification, ensuring long-term availability and regulatory compliance for new designs and production environments requiring environmental standards adherence.

Inventory Availability: The A30BN maintains higher inventory levels (909 Pcs) compared to the obsolete A30BN/6 (694 Pcs), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the A30BN directly replace the A30BN/6 in existing designs?

A: The A30BN provides electrical equivalence across all RF parameters. Physical height difference (10.500" versus 6.000") requires mechanical envelope verification. If the application permits the increased height, direct substitution is feasible.

Q: What is the significance of the height difference between A30BN/6 and A30BN?

A: The A30BN/6 designation indicates a 6-inch height variant, while A30BN specifies 10.500 inches. This difference affects mechanical mounting clearance and spatial integration. Applications with restricted vertical space may require design modification or alternative component selection.

Q: Why is A30BN/6 classified as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The A30BN active variant provides equivalent electrical performance and should be used for new designs and ongoing procurement.

Q: Does RoHS compliance affect substitution eligibility?

A: The A30BN carries RoHS Compliant certification while A30BN/6 status is not specified. For applications requiring environmental compliance documentation, the A30BN is the appropriate selection.

Q: Are there any frequency or impedance limitations when substituting these components?

A: Both components operate identically at 30MHz with 1.5 VSWR and 50W maximum power. No frequency or impedance limitations exist for substitution from an electrical standpoint.

Q: What connector type is used on both components?

A: Both A30BN/6 and A30BN utilize BN connector termination, ensuring mechanical and electrical compatibility at the interface level.
