H2.4-AT(3)-PJ RF Attenuator 3dB 50 Ohm 2.4mm In-Line Module

Part Overview

The H2.4-AT(3)-PJ is an RF attenuator manufactured by Hirose Electric Co., Ltd., designed for RF signal attenuation applications across a broad frequency spectrum. This component operates at 3dB attenuation with 50 Ohm impedance and 1W power handling capability in a 2.4mm in-line module form factor. The part is currently in Last Time Buy status, indicating limited availability from the original manufacturer. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this specific attenuation and impedance profile.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H2.4-AT(3)-PJ are identified based on electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Attenuation Value: 3dB (exact match required)
• Frequency Range: 0 Hz ~ 50 GHz (full spectrum coverage)
• Impedance: 50 Ohms (system impedance standard)
• Power Rating: 1W (thermal and power handling capability)
• ECCN Classification: EAR99 (export control alignment)
• HTSUS Code: 8533.21.0090 (tariff classification alignment)

The BW-V3-1W54+ from Mini-Circuits meets all critical electrical parameters. While the package form factor differs (Module vs. 2.4mm In-Line Module), the electrical specifications and functional performance remain equivalent for RF attenuation applications.

Parameter Comparison

Engineering Selection Recommendations

The BW-V3-1W54+ qualifies as a functional equivalent based on matching electrical specifications: identical 3dB attenuation, 0 Hz ~ 50 GHz frequency coverage, 50 Ohm impedance, and 1W power handling. Both parts share EAR99 export classification and identical HTSUS tariff codes, ensuring regulatory alignment.

The H2.4-AT(3)-PJ is in Last Time Buy status, making the BW-V3-1W54+ a necessary alternative for ongoing production and design support. The Mini-Circuits part carries ROHS3 compliance, exceeding the RoHS Compliant status of the Hirose component, providing enhanced environmental and regulatory assurance.

Package form factor differences (2.4mm In-Line Module vs. Module) require mechanical integration assessment during design implementation. Electrical performance and RF characteristics remain equivalent across both form factors for the specified frequency and power ranges.

Frequently Asked Questions (FAQ)

Q: Can the BW-V3-1W54+ directly replace the H2.4-AT(3)-PJ in existing designs?

A: Electrical substitution is valid based on matching attenuation (3dB), frequency range (0 Hz ~ 50 GHz), impedance (50 Ohms), and power rating (1W). Mechanical integration requires evaluation of the package form factor difference between 2.4mm In-Line Module and Module configurations.

Q: What parameters must remain identical for substitution?

A: Attenuation value, frequency range, impedance, and power rating must match exactly. Both parts meet these criteria. ECCN and HTSUS classifications are also aligned.

Q: Why is the H2.4-AT(3)-PJ in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing production. The BW-V3-1W54+ provides supply continuity for applications requiring 3dB RF attenuation at 50 Ohms across DC to 50 GHz.

Q: Are there compliance differences between the two parts?

A: The BW-V3-1W54+ carries ROHS3 compliance, while the H2.4-AT(3)-PJ is RoHS Compliant. ROHS3 represents a more recent compliance standard. Both parts are EAR99 classified and share identical HTSUS codes.

Q: What should be considered when switching from the Hirose to Mini-Circuits part?

A: Primary considerations are mechanical package integration and PCB layout modifications to accommodate the Module form factor instead of the 2.4mm In-Line Module. Electrical performance and RF characteristics remain equivalent.
