Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by matching the following critical electrical and mechanical parameters:

• Attenuation Value: Must be 4dB
• Frequency Range: Must cover 0 Hz ~ 50 GHz minimum
• Impedance: Must be 50 Ohms
• Power Rating: Must be rated for 1W minimum
• Package Form Factor: Must be compatible with 2.4mm inline module specifications
• Compliance: RoHS and ECCN classifications must be equivalent or superior

The PE7089-4 from Pasternack meets all substitution criteria and is classified as an active product with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

The PE7089-4 is the qualified substitute for the H2.4-AT(4)-PJ based on the following factors:

• All critical electrical parameters match exactly: 4dB attenuation, 0 Hz ~ 50 GHz frequency range, 50 Ohm impedance, and 1W power rating
• The PE7089-4 maintains Active product status, ensuring long-term availability and supply chain continuity
• ROHS3 compliance of the substitute exceeds the RoHS Compliant status of the original part
• Both parts share identical ECCN classification (EAR99), maintaining regulatory consistency
• Mechanical compatibility is maintained through module-based form factors suitable for 2.4mm inline applications

Selection of the PE7089-4 is appropriate for applications requiring the H2.4-AT(4)-PJ specifications where supply of the original part is no longer available.

Frequently Asked Questions (FAQ)

Q: What makes PE7089-4 a valid substitute for H2.4-AT(4)-PJ?

A: The PE7089-4 matches all critical electrical parameters: 4dB attenuation, 0 Hz ~ 50 GHz frequency range, 50 Ohm impedance, and 1W power handling. Both parts are module-based inline attenuators with equivalent mechanical compatibility for 2.4mm applications.

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

A: Last Time Buy status indicates that Hirose Electric has discontinued production of this part. Identifying active substitute parts ensures design continuity and supply chain reliability.

Q: Are there compliance differences between the original and substitute?

A: The PE7089-4 carries ROHS3 compliance, which is equivalent to and compatible with the RoHS Compliant status of the H2.4-AT(4)-PJ. Both parts maintain EAR99 ECCN classification. REACH status of the substitute is listed as REACH Unaffected, which does not impact substitution eligibility.

Q: What is the significance of the 2.4mm form factor?

A: The 2.4mm designation refers to the connector interface standard for this inline module. Both the original and substitute parts are designed for 2.4mm inline applications, ensuring mechanical and electrical compatibility in existing circuit designs.

Q: Can the PE7089-4 be used in new designs replacing the H2.4-AT(4)-PJ?

A: Yes. The PE7089-4 meets all electrical and mechanical specifications of the H2.4-AT(4)-PJ and carries Active product status, making it suitable for both replacement and new design applications.
