RF Attenuator WA04P011XDTL Equivalent & Substitute Parts

Part Overview

The WA04P011XDTL 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 provides 11dB attenuation with 50 Ohm impedance and 100mW power handling capability in a compact 0404 (1010 Metric) package format. The product is currently active and widely available in inventory, with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to inventory constraints, design optimization needs, or specific application requirements where alternative attenuation values are acceptable within system specifications.

Substitute Part Grouping Explanation

Substitution of the WA04P011XDTL is based on strict adherence to the following critical parameters:

Frequency Range compatibility: All substitute parts must operate across the identical 0 Hz ~ 3 GHz frequency band to ensure signal integrity across the intended application spectrum.

Impedance matching: All substitute parts must maintain 50 Ohm impedance to prevent signal reflection and maintain system performance.

Power handling: All substitute parts must support minimum 100mW power dissipation to ensure thermal stability and component reliability.

Package compatibility: All substitute parts must use the 0404 (1010 Metric), Concave package format to ensure mechanical fit and assembly compatibility.

Manufacturer consistency: All substitute parts are sourced from Walsin Technology Corporation to maintain design validation and quality assurance standards.

Compliance standards: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to meet regulatory and environmental requirements.

The attenuation value may vary within the substitute group, provided the alternative attenuation specification remains functionally acceptable within the system design parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the WA04P011XDTL and WA04P012XDTL are active products from Walsin Technology Corporation with identical compliance certifications, including ROHS3 compliance and REACH unaffected status. Both components maintain the same regulatory and environmental qualification status, making them suitable for applications requiring certified component sourcing.

The primary distinction between these parts is the attenuation value: 11dB versus 12dB. Selection between these components depends on the specific attenuation requirement of the system design. Both parts share identical frequency range, impedance, power handling, package format, and compliance characteristics, ensuring mechanical and electrical interchangeability within systems designed to accept either attenuation specification.

Frequently Asked Questions (FAQ)

Q: Can WA04P012XDTL replace WA04P011XDTL in any application?

A: Substitution is valid only if the system design can accommodate 12dB attenuation instead of 11dB. The 1dB difference in attenuation will affect signal level output and must be evaluated against system gain and noise figure requirements.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 0404 (1010 Metric), Concave package format, ensuring identical mechanical fit, PCB footprint, and assembly compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both WA04P011XDTL and WA04P012XDTL are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting identical regulatory and environmental standards.

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

A: Both parts operate across 0 Hz to 3 GHz, providing identical frequency coverage for RF and microwave applications within this bandwidth.

Q: Are impedance and power handling specifications identical?

A: Yes. Both parts maintain 50 Ohm impedance and 100mW power handling capability, ensuring identical electrical performance characteristics outside of attenuation value.

Q: What is the difference in inventory availability?

A: WA04P011XDTL has 752 pieces in stock, while WA04P012XDTL has 27,103 pieces in stock. Availability differences may influence component selection based on procurement timeline requirements.
