Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A09-F2NF-M is determined by the following critical parameters:

Core Compatibility Parameters:

• Frequency (Center/Band): 900MHz
• Antenna Type: Whip, Straight
• Termination: N Type Female
• Mounting Type: Bracket Mount
• Number of Bands: 1

The substitute part A09-F5NF-M shares all core compatibility parameters with the main part. Both antennas operate at 900MHz, utilize identical termination and mounting configurations, and maintain the same single-band design. The primary difference lies in physical height and resulting gain characteristics, which are allowable variations within the whip antenna category for this frequency band.

Parameter Comparison

Engineering Selection Recommendations

The A09-F5NF-M is the manufacturer-recommended substitute for the obsolete A09-F2NF-M. Both parts maintain identical electrical and mechanical interface specifications, ensuring direct compatibility in bracket mount installations with N Type Female connectors.

The A09-F5NF-M carries Active product status, providing long-term availability and supply chain stability compared to the obsolete main part. The substitute meets REACH compliance requirements and is RoHS Compliant, supporting modern regulatory and environmental standards.

Physical height and gain differences between the parts reflect standard design variations within the whip antenna category. The A09-F5NF-M's increased height (25 inches versus 15 inches) and corresponding gain increase (5.1dBi versus 2.1dBi) are direct correlates of antenna length in straight whip designs operating at identical frequency bands.

Frequently Asked Questions (FAQ)

Q: Can the A09-F5NF-M directly replace the A09-F2NF-M in existing installations?

A: Yes. Both parts share identical termination (N Type Female), mounting type (Bracket Mount), and frequency specification (900MHz). Physical installation compatibility is maintained through the bracket mount interface.

Q: What is the primary difference between these two antenna models?

A: The A09-F5NF-M features a 25-inch height compared to the A09-F2NF-M's 15-inch height. This 10-inch increase results in higher gain (5.1dBi versus 2.1dBi), a standard characteristic of whip antenna design where longer elements produce increased directional gain at the same frequency.

Q: Why is the A09-F2NF-M listed as obsolete?

A: The A09-F2NF-M has reached end-of-life status. The A09-F5NF-M is the active substitute offering equivalent interface compatibility with improved product status and regulatory compliance.

Q: Are there packaging differences between these parts?

A: The A09-F2NF-M is specified with "-" packaging notation, while the A09-F5NF-M is supplied in Bulk packaging. Both maintain identical MSL rating (1 - Unlimited), indicating equivalent moisture handling requirements.

Q: Do both antennas meet current regulatory standards?

A: Both parts are REACH Unaffected and carry EAR99 ECCN classification. The A09-F5NF-M additionally carries RoHS Compliance certification, meeting current environmental and regulatory requirements for electronic components.
