CATTEN-03R0 RF Attenuator Equivalent & Substitute Parts

Part Overview

The CATTEN-03R0 is an RF attenuator manufactured by Crystek Corporation, designed for inline attenuation applications across RF and microwave systems. This 3dB attenuator operates across the 0 Hz to 3 GHz frequency range with 1W power handling capability and 50 Ohm impedance, utilizing SMA connectors in a compact in-line module format. The product maintains Active status and is ROHS3 compliant, making it suitable for modern electronic applications requiring environmental compliance.

Equivalent substitute parts are identified when they maintain identical electrical performance parameters: 3dB attenuation value, 1W power rating, 50 Ohm impedance, and SMA in-line module packaging. Substitute components enable procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CATTEN-03R0 are qualified based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Attenuation Value: 3dB (exact match required)
• Power Rating: 1W (exact match required)
• Impedance: 50 Ohms (exact match required)
• Package Type: SMA In-Line Module (exact match required)
• Frequency Range: Minimum 0 Hz ~ 3 GHz coverage (equal or greater range acceptable)

Both identified substitute parts meet these core criteria. The CATTEN-03R0 operates within 0 Hz to 3 GHz; substitute parts with extended frequency ranges (up to 6 GHz or 67 GHz) remain functionally equivalent for applications within the 0-3 GHz band.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, qualifying them for equivalent use in applications requiring environmental regulatory adherence. Selection between CATTEN-03R0 and substitute parts R411803124 or R413V03000 should be based on:

Procurement Considerations: Inventory availability and packaging requirements. CATTEN-03R0 and R413V03000 are supplied in Bulk packaging, while R411803124 is supplied in Box packaging.

Frequency Coverage: For applications strictly limited to 0-3 GHz operation, all three parts are electrically equivalent. R413V03000 provides extended frequency capability to 67 GHz, offering broader application flexibility without performance degradation in the 0-3 GHz band.

Supply Chain Continuity: Current inventory levels are 691 units (CATTEN-03R0), 1155 units (R411803124), and 1108 units (R413V03000), enabling flexible sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can R411803124 or R413V03000 be used as direct replacements for CATTEN-03R0?

A: Yes. Both parts are parametric equivalents meeting the core electrical specifications: 3dB attenuation, 1W power handling, 50 Ohm impedance, and SMA in-line module packaging. All three maintain identical performance within the 0-3 GHz frequency band.

Q: What is the difference between R411803124 and R413V03000?

A: Both are Radiall USA manufactured 3dB, 1W, 50 Ohm SMA attenuators. R411803124 specifies 0-3 GHz frequency range, while R413V03000 extends to 67 GHz. For 0-3 GHz applications, both deliver equivalent performance. Packaging differs: R411803124 is supplied in Box format; R413V03000 in Bulk format.

Q: Does the extended frequency range of R413V03000 affect its performance in 0-3 GHz applications?

A: No. Extended frequency range capability does not degrade performance within the 0-3 GHz operating band. The 3dB attenuation, 1W power rating, and 50 Ohm impedance remain constant across the specified frequency range.

Q: Are all three parts ROHS3 compliant?

A: Yes. CATTEN-03R0, R411803124, and R413V03000 all maintain ROHS3 compliance status.

Q: What packaging options are available?

A: CATTEN-03R0 and R413V03000 are supplied in Bulk packaging. R411803124 is supplied in Box packaging. Packaging selection may depend on inventory management and procurement requirements.
