Key Parameters

Substitute Part Grouping Explanation

Substitution of RF attenuators is determined by strict equivalence of electrical and mechanical parameters. The following criteria establish substitutability for the H2.4-AT(8)-PJ:

Critical Electrical Parameters:

• Attenuation Value: 8dB (exact match required)
• Frequency Range: 0 Hz ~ 50 GHz (minimum coverage required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 1W (minimum requirement)

Mechanical Parameters:

• Package / Case: 2.4mm In-Line Module or equivalent module form factor
• Series Compatibility: 2.4mm connector interface

Compliance Parameters:

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• ECCN Classification: EAR99

The PE7089-8 from Pasternack meets all critical electrical parameters and maintains RoHS compliance, establishing it as a direct substitute for the H2.4-AT(8)-PJ.

Parameter Comparison

Engineering Selection Recommendations

Both components satisfy identical attenuation, frequency, impedance, and power specifications. The PE7089-8 maintains active product status, ensuring ongoing availability and supply chain continuity compared to the Last Time Buy status of the H2.4-AT(8)-PJ. Both components carry equivalent export classifications (EAR99) and maintain RoHS compliance standards. The PE7089-8 is suitable for direct substitution in applications requiring 8dB attenuation across DC to 50 GHz frequency ranges at 50 Ohm impedance with 1W power handling.

Frequently Asked Questions (FAQ)

Q: Can the PE7089-8 be used as a direct replacement for the H2.4-AT(8)-PJ?

A: Yes. Both components share identical electrical specifications: 8dB attenuation, 0 Hz ~ 50 GHz frequency range, 50 Ohm impedance, and 1W power rating. Both are module form factors compatible with 2.4mm connector interfaces.

Q: What is the difference in packaging between these two parts?

A: The H2.4-AT(8)-PJ is supplied in Tray packaging, while the PE7089-8 is supplied in Bag packaging. This difference does not affect electrical performance or mechanical compatibility.

Q: Are there compliance differences between the two parts?

A: Both components are RoHS compliant. The H2.4-AT(8)-PJ carries RoHS Compliant status, while the PE7089-8 carries ROHS3 Compliant status. Both meet current regulatory requirements. The PE7089-8 is additionally noted as REACH Unaffected.

Q: Why is the H2.4-AT(8)-PJ marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing production. The PE7089-8, with Active product status, provides supply continuity for ongoing applications requiring equivalent RF attenuation performance.

Q: Are there any frequency or power limitations when substituting?

A: No. Both components operate identically across the full 0 Hz ~ 50 GHz frequency range with 1W power handling. Substitution does not introduce frequency or power limitations.
