RF Attenuator AT-2210(40) Equivalent & Substitute Parts

Part Overview

The AT-2210(40) is a 10dB RF attenuator manufactured by Hirose Electric Co Ltd, designed for 50-ohm RF systems operating from DC to 2.5 GHz with 1W power handling capability in an SMA in-line module configuration. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs. Substitute parts must maintain the core electrical parameters: 10dB attenuation, 50-ohm impedance, 1W power rating, and SMA connector interface.

Key Parameters

Parameter	Value
Attenuation Value	10dB
Frequency Range	0 Hz ~ 2.5 GHz
Power Rating	1W
Impedance	50 Ohms

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Attenuation Value: Must be 10dB (±0dB tolerance for direct substitution)
Impedance: Must be 50 Ohms
Power Rating: Must be ≥1W
Package / Case: Must be SMA In-Line Module
Frequency Range: Must encompass or exceed the original 0 Hz ~ 2.5 GHz specification

Parts are grouped into two categories:

Full Equivalents (all parameters match or exceed original specifications):

AT-110-WP1(40) by Hirose Electric Co Ltd

Engineering Selection Recommendations

Primary Substitutes (Active status, full parameter compliance):

AT-110-WP1(40) is the direct equivalent from the original manufacturer Hirose Electric Co Ltd, maintaining RoHS compliance and offering extended frequency coverage to 18 GHz. This part is recommended for applications requiring manufacturer continuity and proven compatibility with existing Hirose component ecosystems.

R413V10000 by Radiall USA, Inc. provides the broadest frequency coverage (0 Hz ~ 67 GHz) while maintaining all core electrical parameters. This part is suitable for applications requiring future-proof frequency headroom beyond the original 2.5 GHz specification.

CATTEN-0100 by Crystek Corporation is suitable for applications operating within the 0 Hz ~ 3 GHz band and offers ROHS3 compliance. Inventory availability is comparable to other active substitutes.

R411810124 by Radiall USA, Inc. provides 0 Hz ~ 6 GHz coverage with ROHS3 compliance and is suitable for mid-range frequency applications.

Secondary Substitute (Attenuation variance):

R411811124 by Radiall USA, Inc. differs in attenuation value (11dB vs. 10dB) and should only be selected when the system design can accommodate the 1dB attenuation increase or when this value is specifically required.

Compliance Considerations:

All active substitute parts maintain RoHS or ROHS3 compliance. The original AT-2210(40) is RoHS Compliant; substitute parts offer equivalent or enhanced compliance status (ROHS3 Compliant or REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can AT-110-WP1(40) be used as a direct replacement for AT-2210(40)?

A: Yes. Both parts share identical attenuation (10dB), impedance (50 Ohms), power rating (1W), and SMA in-line module packaging. AT-110-WP1(40) extends frequency coverage to 18 GHz, which encompasses the original 2.5 GHz specification. Both are RoHS compliant.

Q: What is the difference between 10dB and 11dB attenuation?

A: R411811124 provides 11dB attenuation instead of 10dB. This 1dB difference represents approximately 26% greater signal reduction. Use this part only if your system design specifically requires 11dB attenuation or can tolerate the increased loss.

Q: Which substitute offers the widest frequency coverage?

A: R413V10000 operates from 0 Hz to 67 GHz, providing the broadest frequency range among all substitutes. This part is suitable for applications requiring extended frequency capability beyond the original 2.5 GHz specification.

Q: Are all substitutes available in the same SMA connector configuration?

A: Yes. All listed substitute parts use SMA in-line module packaging, ensuring mechanical and electrical compatibility with existing SMA-based RF systems.

Q: What compliance certifications apply to these substitutes?

A: All active substitute parts maintain RoHS or ROHS3 compliance. The original AT-2210(40) is RoHS Compliant. Substitute parts offer equivalent or enhanced compliance status suitable for regulated applications.

Q: Can I use R413V10000 in a 2.5 GHz application?

A: Yes. R413V10000 operates across 0 Hz ~ 67 GHz, which fully encompasses the 2.5 GHz operating range. The extended frequency capability does not affect performance at 2.5 GHz.
