ANT-458-SP Equivalent & Substitute Parts

Part Overview

The ANT-458-SP is a 458MHz chip RF antenna manufactured by TE Connectivity Linx, designed for ISM band applications including alarms, remote control, and security systems. This surface mount component operates across the 454MHz to 462MHz frequency range with a gain of -5.4dBi and VSWR of 1.9. The part is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the constraints of the target application frequency band and mounting requirements.

Key Parameters

Substitute Part Grouping Explanation

The PA.12 from Taoglas Limited is listed as a substitute part number in the source data. However, direct substitution is not supported based on the provided electrical parameters. The PA.12 operates at 2.4GHz (2.4GHz – 2.484GHz frequency range), which is outside the 458MHz ISM band specification of the ANT-458-SP. Substitution between these parts is only valid when the target application operates in the 2.4GHz band and does not require 458MHz frequency operation.

Substitution criteria are determined by:

• Frequency band compatibility (center frequency and operating range)
• Antenna type (chip configuration)
• Mounting method (surface mount with solder termination)
• Physical height constraints
• Compliance certifications (RoHS, REACH)

Parameter Comparison

Engineering Selection Recommendations

Selection between ANT-458-SP and PA.12 must be based on the operating frequency requirement of the target application:

• For 458MHz ISM band applications (alarms, remote control, security systems operating in the 454MHz – 462MHz range): ANT-458-SP is the required selection. PA.12 cannot be substituted.

• For 2.4GHz band applications (Bluetooth, WLAN, Zigbee operating in the 2.4GHz – 2.484GHz range): PA.12 is the appropriate selection. ANT-458-SP cannot be substituted.

Both parts maintain active product status and full compliance with RoHS and REACH regulations. Physical height difference (1.50mm vs 3.00mm) requires verification of PCB layout clearance when considering any design change. MSL rating difference (1 vs 3) affects moisture-sensitive storage and handling procedures during manufacturing.

Frequently Asked Questions (FAQ)

Q: Can PA.12 replace ANT-458-SP in a 458MHz application?

A: No. PA.12 operates at 2.4GHz and cannot function in 458MHz circuits. Frequency band mismatch makes this substitution invalid regardless of other compatible parameters.

Q: Can ANT-458-SP replace PA.12 in a Bluetooth application?

A: No. ANT-458-SP operates at 458MHz and cannot function in 2.4GHz Bluetooth circuits. The frequency bands are incompatible.

Q: What parameters determine if these parts can be substituted?

A: Primary substitution criteria are frequency band (center frequency and operating range), antenna type, mounting method, and termination style. Both parts share compatible mounting (surface mount, solder termination) and antenna type (chip), but operate in different frequency bands, making them non-interchangeable.

Q: Are there physical size constraints when considering substitution?

A: Yes. ANT-458-SP has a maximum height of 1.50mm while PA.12 is 3.00mm. If a design change is considered, PCB layout clearance must be verified to ensure the taller component does not interfere with adjacent components or enclosure constraints.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and REACH unaffected. ANT-458-SP carries RoHS Compliance while PA.12 carries ROHS3 Compliance. Both are acceptable for regulated applications. MSL ratings differ (1 vs 3), affecting moisture handling during manufacturing and storage.

Q: What is the packaging difference between these parts?

A: ANT-458-SP is supplied in Bag packaging while PA.12 is supplied in Tape & Reel (TR) packaging. Packaging format may affect procurement, handling, and assembly line compatibility.
