Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by matching the following critical parameters:

• Attenuation Value: Must be 0dB
• Impedance: Must be 50 Ohms
• Package / Case: Must be SMA In-Line Module
• Power Rating: Must support minimum 1W
• Connector Type: SMA interface required

Two substitute parts meet these core criteria with variations in frequency range coverage:

Parametric Equivalent (Full Frequency Coverage): AT-100-(0)-WP1(40) maintains identical electrical specifications and extends operational capability across the full 0 Hz to 18 GHz range with Active product status.

Parametric Equivalent (Limited Frequency Coverage): R411800124 provides 0dB attenuation at 50 Ohms with 1W power handling but operates within a reduced frequency range of 0 Hz to 6 GHz.

Parameter Comparison

Engineering Selection Recommendations

AT-100-(0)-WP1(40) is the primary substitute for AT-200-(0)(40). Both components are manufactured by Hirose Electric Co Ltd with identical electrical parameters and full 18 GHz frequency coverage. The AT-100 series maintains Active product status, ensuring long-term availability and supply chain stability. This part is recommended for direct replacement in applications requiring the full specified frequency range.

R411800124 serves as an alternative substitute when frequency requirements do not exceed 6 GHz. Manufactured by Radiall USA, Inc., this component maintains all core electrical specifications (0dB attenuation, 50 Ohm impedance, 1W power handling, SMA in-line module) and holds Active product status. Selection of this part requires confirmation that the application operates within the 0 Hz to 6 GHz frequency band.

Both substitute parts carry RoHS Compliance and EAR99 export classification matching the original component.

Frequently Asked Questions (FAQ)

Q: Can AT-100-(0)-WP1(40) replace AT-200-(0)(40) in all applications?

A: Yes, for applications operating within 0 Hz to 18 GHz. The AT-100 series provides identical attenuation (0dB), impedance (50 Ohms), power handling (1W), and connector type (SMA in-line module). Both are Hirose Electric products with RoHS compliance.

Q: What is the key limitation of R411800124 as a substitute?

A: The frequency range is limited to 0 Hz to 6 GHz, compared to the original part's 0 Hz to 18 GHz specification. This part is suitable only for applications that do not require operation above 6 GHz.

Q: Are there packaging differences between the substitute parts?

A: All three parts use SMA in-line module packaging. No mechanical or connector interface changes are required for substitution.

Q: Why is AT-200-(0)(40) in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this part number. AT-100-(0)-WP1(40) represents the active replacement in the Hirose product line.

Q: Do the substitute parts have the same compliance certifications?

A: Yes. All three parts are RoHS Compliant and classified as EAR99 for export purposes, matching the original component's regulatory status.

Q: Can I use R411800124 if my application operates at 12 GHz?

A: No. R411800124 is specified for 0 Hz to 6 GHz operation. Use AT-100-(0)-WP1(40) for applications requiring operation above 6 GHz.
