Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JEGIDHB are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 26.5 GHz
• Operating Temperature: -65°C ~ 165°C
• Voltage Rating: 335 V

Mechanical Parameters (Must Match):

• Mounting Type: Panel Mount, Through Hole
• Mounting Feature: Flange
• Contact Termination: Solder
• Shield Termination: Solder

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Product Status: Active

The RFSMAA2JEGIDHB features a two-hole flange mounting configuration. Substitute RFSMAA2JEGACDD maintains identical electrical and mechanical specifications with the same two-hole mounting pattern. Substitute RFSMAA4JCCACDD provides electrical equivalence but features a four-hole flange mounting configuration, suitable for applications where additional mechanical stability or different PCB layout requirements are present.

Parameter Comparison

Engineering Selection Recommendations

RFSMAA2JEGACDD is the direct parametric equivalent to RFSMAA2JEGIDHB. Both connectors share identical electrical specifications, mechanical mounting configuration with two flange holes, and compliance certifications. Selection of RFSMAA2JEGACDD is appropriate when RFSMAA2JEGIDHB inventory is unavailable, as it provides complete functional equivalence without design modification.

RFSMAA4JCCACDD is an electrical equivalent with a modified mechanical mounting configuration. This connector maintains all electrical parameters and compliance requirements but features a four-hole flange mounting pattern instead of two holes. Selection of RFSMAA4JCCACDD requires PCB layout modification to accommodate the additional mounting holes. This variant is suitable for applications requiring enhanced mechanical stability or where PCB design permits the four-hole configuration.

All three connectors maintain Active product status and ROHS3 Compliance, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JEGACDD be used as a direct replacement for RFSMAA2JEGIDHB without PCB modification?
