Substitute Part Grouping Explanation

Substitute parts for the AT-430 are qualified based on matching the following critical parameters: 30dB attenuation value, 50 Ohm impedance, 2W power rating, and N-Type in-line module package. Frequency range variations are permitted within the substitute group, as long as the minimum frequency range encompasses the AT-430's 0 Hz to 13 GHz specification or provides equivalent coverage for the intended application. All substitute parts maintain identical mechanical and electrical interfaces, ensuring direct form-fit-function replacement capability.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status, ensuring ongoing availability and manufacturer support. For applications requiring full frequency coverage matching the AT-430's 0 Hz to 13 GHz range, ATT-0219-30-NNN-02 and R414730150 provide extended frequency capability to 18 GHz. ATT-0218-30-NNN-02 and R414730000 cover the 0 Hz to 12.4 GHz range, which encompasses the AT-430 specification. The 6830_N-50-1/1--_NE and R412730000 provide limited frequency coverage to 6 GHz and 4 GHz respectively, suitable only for applications operating within these reduced frequency bands. RoHS compliance status should be verified against design requirements; ATT-0218-30-NNN-02 and ATT-0219-30-NNN-02 maintain RoHS Compliant certification matching the original AT-430.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts directly replace the AT-430? A: Yes, all listed parts are parametric equivalents with identical 30dB attenuation, 50 Ohm impedance, 2W power rating, and N-Type in-line module package. Direct mechanical and electrical substitution is supported.

Q: What is the significance of frequency range differences among substitutes? A: Frequency range indicates the upper frequency limit of attenuation performance. Parts with frequency ranges at or exceeding 13 GHz (ATT-0219-30-NNN-02, R414730150) provide full coverage for the AT-430 application. Parts with lower frequency limits (6830_N-50-1/1--_NE at 6 GHz, R412730000 at 4 GHz) are suitable only for applications operating within those frequency bands.

Q: Are all substitute parts RoHS compliant? A: ATT-0218-30-NNN-02, ATT-0219-30-NNN-02, and 6830_N-50-1/1--_NE carry RoHS compliance certifications. R412730000, R414730000, and R414730150 do not specify RoHS status in available documentation.

Q: What packaging options are available? A: All substitute parts are supplied in Bulk packaging as N-Type in-line modules, consistent with the AT-430 original packaging.

Q: Which substitute offers the best frequency coverage for general-purpose applications? A: ATT-0219-30-NNN-02 and R414730150 both extend to 18 GHz, providing the broadest frequency coverage and ensuring compatibility with applications spanning the full AT-430 range and beyond.
