EXC450SMV RF Antenna Equivalent & Substitute Parts

Part Overview

The EXC450SMV is a 460MHz Bluetooth and Wi-Fi whip antenna manufactured by TE Connectivity Laird. This straight RF antenna features an SMA male connector mount and operates across the 450MHz to 470MHz frequency band within the UHF spectrum. The part is currently classified as obsolete, making identification of active equivalent substitutes essential for ongoing procurement and system integration.

The EXC450SMV is designed for applications requiring compact, fixed-frequency RF transmission and reception in the UHF band. Its obsolete status necessitates the identification of functionally equivalent active alternatives to maintain supply chain continuity and ensure design compatibility in new production runs.

Substitute Part Grouping Explanation

Substitution of the EXC450SMV is determined by strict equivalence across the following critical parameters:

Frequency Compatibility: The substitute part must operate at the same center frequency (460MHz) and support the identical frequency range (450MHz ~ 470MHz) to ensure proper RF performance in Bluetooth and Wi-Fi applications.

Antenna Configuration: The substitute must maintain the same antenna type (whip, straight) and physical height (6.900" / 175.26mm) to preserve mechanical fit and RF radiation characteristics.

Electrical Interface: The substitute must feature an SMA male connector termination to ensure direct compatibility with existing RF circuit designs and connector assemblies.

Performance Specifications: The substitute must meet or exceed the VSWR specification (1.5) and support the maximum power rating (50W) to maintain signal integrity and thermal performance.

Compliance & Standards: The substitute must maintain RoHS compliance and MSL rating (1 - Unlimited) to satisfy regulatory and environmental requirements.

Series Continuity: The substitute is identified from the same EXC series to ensure design lineage and manufacturing consistency.

The EXC450SM meets all these criteria as a parametric equivalent and serves as the active substitute for the obsolete EXC450SMV.

Parameter Comparison

Engineering Selection Recommendations

The EXC450SM is the direct parametric equivalent for the obsolete EXC450SMV. All electrical, mechanical, and RF performance specifications are identical across both parts. The primary distinction is product status: the EXC450SMV is obsolete, while the EXC450SM maintains active production status.

Both parts carry RoHS compliance certification and MSL rating 1 (unlimited moisture sensitivity), satisfying regulatory and environmental requirements for industrial and commercial applications. The EXC450SM is available in bulk packaging, whereas the EXC450SMV was supplied in standard packaging.

For new designs, procurement, and production applications requiring a 460MHz UHF whip antenna with SMA male termination, the EXC450SM is the appropriate selection. Existing designs currently specified for the EXC450SMV can transition directly to the EXC450SM without modification to RF circuits, mechanical assemblies, or connector interfaces.

Frequently Asked Questions (FAQ)

Q: Can the EXC450SM directly replace the EXC450SMV in existing designs?

A: Yes. The EXC450SM is a parametric equivalent with identical frequency response (460MHz center, 450MHz ~ 470MHz range), antenna configuration (whip, straight), physical dimensions (6.900" height), connector type (SMA male), and performance specifications (VSWR 1.5, 50W maximum power). No circuit modifications or mechanical redesign is required.

Q: What is the primary reason for substitution?

A: The EXC450SMV is classified as obsolete. The EXC450SM is the active equivalent from TE Connectivity Laird, ensuring continued availability and supply chain reliability.

Q: Are there packaging differences between these parts?

A: The EXC450SMV was supplied in standard packaging, while the EXC450SM is available in bulk packaging. This difference does not affect electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the EXC450SMV and EXC450SM are RoHS compliant and carry MSL rating 1 (unlimited). They satisfy identical regulatory and environmental requirements.

Q: What applications are these antennas designed for?

A: Both parts are specified for Bluetooth and Wi-Fi applications operating in the 450MHz ~ 470MHz UHF band. They are suitable for wireless communication systems requiring fixed-frequency, single-band RF transmission and reception.

Q: Is the VSWR specification the same for both parts?

A: Yes. Both parts specify a VSWR of 1.5, indicating equivalent impedance matching and return loss performance across the operating frequency range.

Q: Can these antennas be used interchangeably in production?

A: Yes. The EXC450SM can be used as a direct substitute in production environments. All electrical, mechanical, and RF characteristics are identical, allowing seamless integration into existing manufacturing processes and bill-of-materials specifications.
