Part Overview

The AT-410(40) is a 10dB RF attenuator manufactured by Hirose Electric Co Ltd, designed for inline attenuation across 0 Hz to 13 GHz with 50 Ohm impedance and 2W power handling in an N-Type connector configuration. This part is designated as Last Time Buy, indicating end-of-life status. Equivalent and substitute parts are identified based on matching electrical specifications: 10dB attenuation value, 50 Ohm impedance, 2W power rating, and N-Type In-Line Module packaging.

Key Parameters

Parameter	AT-410(40) Specification
Attenuation Value	10dB

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Attenuation Value: 10dB (exact match required)
Impedance: 50 Ohms (exact match required)
Power Rating: 2W (exact match required)
Package / Case: N-Type In-Line Module (exact match required)
Frequency Range: Parts with frequency ranges equal to or exceeding the AT-410(40) specification of 0 Hz ~ 13 GHz are acceptable

Parts with 11dB attenuation or frequency ranges below 13 GHz are listed for reference but do not meet full substitution criteria. Parts with reduced frequency capability (below 13 GHz) may be suitable only for applications operating within their specified frequency limits.

Engineering Selection Recommendations

Full electrical and mechanical equivalents to AT-410(40) with 10dB attenuation, 50 Ohm impedance, 2W power, and N-Type In-Line Module packaging across the required 0 Hz ~ 13 GHz frequency range are:

ATT-0219-10-NNN-02 (Cinch Connectivity Solutions Midwest Microwave): Extends frequency coverage to 18 GHz with ROHS3 compliance and active product status
ATT-0389-10-NNN-02 (Cinch Connectivity Solutions Midwest Microwave): Extends frequency coverage to 18 GHz with RoHS compliance and active product status
R414710000 (Radiall USA, Inc.): Covers 0 Hz ~ 12.4 GHz with ROHS3 compliance and active product status
R414710150 (Radiall USA, Inc.): Extends frequency coverage to 18 GHz with active product status

Parts with reduced frequency capability are suitable only for applications operating within their specified frequency limits:

ATT-0218-10-NNN-02 (Cinch Connectivity Solutions Midwest Microwave): Limited to 12.4 GHz
6810_N-50-1/1--_NE (Huber+Suhner, Inc.): Limited to 6 GHz
R412710000 (Radiall USA, Inc.): Limited to 2 GHz

Parts with 11dB attenuation do not meet exact substitution criteria and are listed for reference only.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a lower frequency range than the AT-410(40)?

A: Substitute parts with frequency ranges below 13 GHz may be used only if your application operates entirely within the lower frequency specification. For example, R412710000 (0 Hz ~ 2 GHz) is suitable only for applications not exceeding 2 GHz. Verify your system's operating frequency requirements before selection.

Q: Are parts with 11dB attenuation acceptable substitutes?

A: No. The AT-410(40) specifies 10dB attenuation. Parts with 11dB attenuation (ATT-0218-11-NNN-02, ATT-0219-11-NNN-02, R412711000) do not meet the electrical specification and are not direct substitutes.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate RoHS compliance. ROHS3 represents compliance with the most recent RoHS 3 directive. Both are acceptable for RoHS-compliant applications.

Q: Can I use a substitute part with a higher frequency range?

A: Yes. Parts with frequency ranges equal to or exceeding 13 GHz (such as ATT-0219-10-NNN-02, ATT-0389-10-NNN-02, and R414710150 rated to 18 GHz) are fully compatible and provide extended frequency capability.

Q: Are all substitute parts in active production status?

A: The AT-410(40) is designated Last Time Buy. All listed substitute parts with 10dB attenuation, 50 Ohm impedance, 2W power, and N-Type In-Line Module packaging are in Active product status, ensuring continued availability.

Q: Does packaging differ between manufacturers?

A: All listed parts use N-Type In-Line Module packaging. Physical dimensions and connector specifications are standardized for this package type across manufacturers.
