Key Parameters

Substitute Part Grouping Explanation

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

• Attenuation Value: 7dB (exact match required)
• Frequency Range: 0 Hz ~ 50 GHz (minimum coverage requirement)
• Impedance: 50 Ohms (standard RF impedance)
• Power Rating: 1W (minimum power handling)
• Package Form Factor: 2.4mm In-Line Module or equivalent module configuration
• Regulatory Compliance: RoHS and ECCN classification alignment

The PE7089-7 from Pasternack meets all substitution criteria through matching electrical specifications and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The PE7089-7 serves as a direct functional equivalent to the H2.4-AT(7)-PJ based on matching electrical specifications and regulatory compliance. Both components satisfy identical attenuation, frequency, impedance, and power requirements. The PE7089-7 maintains active product status, providing supply continuity for applications currently using the H2.4-AT(7)-PJ. ROHS3 compliance of the substitute part exceeds the RoHS Compliant status of the original component. Both parts carry EAR99 ECCN classification, ensuring consistent export control treatment.

Frequently Asked Questions (FAQ)

Q: Can the PE7089-7 replace the H2.4-AT(7)-PJ in existing designs?

A: Yes. Both components provide identical attenuation (7dB), frequency response (0 Hz ~ 50 GHz), impedance (50 Ohms), and power handling (1W). Electrical performance is equivalent for inline RF attenuation applications.

Q: What is the difference between the 2.4mm In-Line Module and Module package designations?

A: The H2.4-AT(7)-PJ specifies 2.4mm In-Line Module form factor, while the PE7089-7 is designated as Module. Both are inline connector-based configurations suitable for 2.4mm RF systems. Physical compatibility should be verified against specific connector requirements in your application.

Q: Are there compliance differences between these parts?

A: The PE7089-7 carries ROHS3 compliance, which represents a more recent RoHS standard iteration than the RoHS Compliant designation of the H2.4-AT(7)-PJ. Both parts meet EAR99 export control requirements. REACH status differs (PE7089-7 is REACH Unaffected), but this does not affect functional substitution.

Q: Why is the H2.4-AT(7)-PJ in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The PE7089-7 remains in Active status, making it the appropriate long-term alternative for new designs and ongoing procurement.

Q: Are there inventory considerations for these parts?

A: The H2.4-AT(7)-PJ has 904 pieces in stock (Last Time Buy), while the PE7089-7 has 972 pieces available (Active status). For new projects, the PE7089-7 offers superior supply continuity.
