RF Attenuator WA04P019XGTL Equivalent & Substitute Parts

Part Overview

The WA04P019XGTL is an RF attenuator manufactured by Walsin Technology Corporation, designed for RF signal attenuation applications across the 0 Hz to 3 GHz frequency range. This component operates at 50 Ohms impedance with 100mW power handling capability in a compact 0404 (1010 Metric) package format. The part is currently in active production status and maintains full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Alternative models may be required due to inventory constraints, specific attenuation value requirements, or application-specific design parameters.

Substitute Part Grouping Explanation

The WA04P020XHTL is identified as a parametric equivalent to the WA04P019XGTL based on the following matching criteria:

Matching Parameters:

• Manufacturer: Walsin Technology Corporation
• Frequency Range: 0 Hz ~ 3 GHz
• Impedance: 50 Ohms
• Power Rating: 100mW
• Package / Case: 0404 (1010 Metric), Concave
• Packaging Type: Tape & Reel (TR)
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)
• REACH Status: REACH Unaffected

Differing Parameter:

• Attenuation Value: 20dB (versus 19dB in the main part)

The substitute part maintains electrical and mechanical compatibility across all parameters except attenuation value, which differs by 1dB. Selection between these parts depends on the specific attenuation requirement of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both WA04P019XGTL and WA04P020XHTL are active production components from Walsin Technology Corporation with identical compliance certifications and regulatory status. Selection between these parts is determined by the circuit design requirement for attenuation value. The WA04P019XGTL provides 19dB attenuation, while the WA04P020XHTL provides 20dB attenuation. Both parts maintain full ROHS3 compliance, REACH unaffected status, and identical electrical and mechanical specifications across frequency range, impedance, power rating, and package format. The 1dB difference in attenuation value represents the only technical distinction between these components.

Frequently Asked Questions (FAQ)

Q: Can WA04P020XHTL be used as a direct replacement for WA04P019XGTL?

A: The WA04P020XHTL is mechanically and electrically compatible with the WA04P019XGTL across all parameters except attenuation value. Direct substitution is possible only if the application circuit design permits a 1dB increase in signal attenuation.

Q: Are the package dimensions identical between these parts?

A: Both parts use the 0404 (1010 Metric) package format with concave configuration. Package dimensions and PCB footprints are identical, allowing for direct board-level substitution from a mechanical standpoint.

Q: Do both parts meet the same compliance requirements?

A: Both WA04P019XGTL and WA04P020XHTL are ROHS3 compliant, REACH unaffected, and carry identical regulatory certifications. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the frequency operating range for both parts?

A: Both parts operate across the 0 Hz to 3 GHz frequency range with 50 Ohms impedance and 100mW power handling capability.

Q: How does the 1dB attenuation difference affect circuit performance?

A: The attenuation difference is determined by application requirements. The WA04P019XGTL provides 19dB attenuation while the WA04P020XHTL provides 20dB attenuation. Selection depends on the specific signal level reduction required by the circuit design.
