Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by the following critical parameters: attenuation value, impedance, power rating, package type, and connector interface. All substitute parts listed maintain the core electrical specifications of 10dB attenuation, 50-ohm impedance, and 1W power handling in SMA in-line module packaging.

The substitute parts are grouped into two categories based on frequency range coverage:

Category 1: Limited Frequency Range (0 Hz ~ 6 GHz)

• R411810124 provides equivalent performance within a narrower frequency band suitable for applications not requiring extended frequency coverage

Category 2: Extended Frequency Range (0 Hz ~ 67 GHz)

• R413V10000 extends frequency capability significantly beyond the main part, supporting ultra-wideband applications

Both substitutes maintain identical attenuation, power, impedance, and mechanical package specifications, ensuring direct functional replacement within their respective frequency operating windows.

Parameter Comparison

Engineering Selection Recommendations

Selection between the AT-110-WP1(40) and its substitutes depends on application frequency requirements and compliance certifications:

AT-110-WP1(40) is the primary specification for applications requiring 18 GHz maximum frequency coverage with RoHS compliance and defined moisture sensitivity characteristics.

R411810124 serves applications with frequency requirements limited to 6 GHz or below. This substitute maintains identical electrical and mechanical specifications within its frequency band and provides ROHS3 compliance with REACH affected status documentation.

R413V10000 is suitable for ultra-wideband applications extending to 67 GHz. This substitute provides the broadest frequency coverage and ROHS3 compliance. Moisture sensitivity is not applicable for this part, indicating different construction or material composition.

All three parts maintain active production status and are electrically equivalent within their specified frequency ranges, 50-ohm impedance, 10dB attenuation, and 1W power handling.

Frequently Asked Questions (FAQ)

Q: Can R411810124 be used as a direct replacement for AT-110-WP1(40)?

A: R411810124 is electrically equivalent for applications operating at frequencies up to 6 GHz. For applications requiring operation above 6 GHz up to 18 GHz, this substitute is not suitable. Verify your application's maximum operating frequency before selection.

Q: What is the primary difference between R413V10000 and the main part?

A: R413V10000 extends frequency coverage to 67 GHz compared to the AT-110-WP1(40)'s 18 GHz maximum. All other electrical parameters (10dB attenuation, 1W power, 50-ohm impedance) and mechanical specifications (SMA in-line module) remain identical. Moisture sensitivity level differs due to construction differences.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts use SMA in-line module packaging, ensuring mechanical compatibility in standard SMA connector applications.

Q: What compliance certifications apply to each part?

A: AT-110-WP1(40) carries RoHS compliance. R411810124 and R413V10000 both carry ROHS3 compliance. R411810124 and R413V10000 are both REACH affected. Verify compliance requirements for your specific application and region.

Q: Which substitute should I select for a 12 GHz application?

A: R413V10000 is the appropriate substitute, as it covers frequencies up to 67 GHz. R411810124 is limited to 6 GHz and is not suitable for 12 GHz operation.
