Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT-220(40) are qualified based on matching the following critical parameters: 20dB attenuation value, 50 Ohm impedance, 1W power rating, and SMA in-line module package configuration. Frequency range compatibility is evaluated within the operational bandwidth requirements of the application. All listed substitutes maintain these core electrical and mechanical specifications, enabling direct functional replacement in RF signal attenuation applications.

Parameter Comparison

Engineering Selection Recommendations

AT-120-WP1(40) from Hirose Electric Co Ltd provides the most direct substitution path, matching all electrical parameters and frequency range specifications while maintaining Active product status and RoHS compliance. This part is recommended as the primary replacement for AT-220(40) applications.

6820.19.A from Huber+Suhner, Inc. offers equivalent electrical and mechanical specifications with Active status, suitable for applications where multi-source qualification is required.

R411820124 from Radiall USA, Inc. maintains all core electrical parameters but operates within a reduced frequency range of 0 Hz to 6 GHz. This part is suitable only for applications operating within this bandwidth limitation.

R413V20000 from Radiall USA, Inc. provides extended frequency coverage to 67 GHz while maintaining the 20dB attenuation and 1W power rating, applicable for broadband RF systems requiring higher frequency operation.

Frequently Asked Questions (FAQ)

Q: Can AT-120-WP1(40) directly replace AT-220(40) in all applications?

A: Yes. AT-120-WP1(40) matches all critical parameters: 20dB attenuation, 0 Hz to 18 GHz frequency range, 50 Ohm impedance, 1W power rating, and SMA in-line module package. Both parts are RoHS compliant.

Q: What is the key difference between R411820124 and the primary AT-220(40) specification?

A: R411820124 operates within 0 Hz to 6 GHz frequency range, compared to AT-220(40)'s 0 Hz to 18 GHz range. All other electrical parameters remain equivalent. Use R411820124 only in applications confirmed to operate within 6 GHz maximum frequency.

Q: Is R413V20000 suitable for AT-220(40) replacement in standard RF applications?

A: R413V20000 maintains all core electrical specifications (20dB, 50 Ohms, 1W, SMA package) and extends frequency coverage to 67 GHz. It is suitable for AT-220(40) replacement in any application operating at or below 18 GHz.

Q: What compliance certifications should be verified for substitute part selection?

A: RoHS compliance status varies across substitutes. AT-120-WP1(40) and AT-220(40) are RoHS Compliant. R411820124 and R413V20000 are ROHS3 Compliant. Verify compliance requirements for your specific application and regulatory jurisdiction before final part selection.

Q: Are all substitute parts available in the same packaging format?

A: All listed substitute parts are supplied in SMA in-line module package configuration, maintaining mechanical compatibility with AT-220(40) form factor and connector interface.
