Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the 2118315-2 is based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Dual-band RF antenna configuration supporting 2.4GHz and 5GHz frequency ranges
• Surface mount solder termination
• Maximum height constraint of 0.169" (4.30mm)
• Moisture sensitivity level MSL 1 (Unlimited)
• Compliance with EAR99 export classification

The substitute part 2118788-2 meets these core electrical and mechanical parameters, enabling functional replacement in applications requiring dual-band wireless connectivity. Both components utilize solder surface mount technology and maintain compatible physical dimensions within the specified height envelope.

Parameter Comparison

Engineering Selection Recommendations

The 2118315-2 is classified as obsolete, making the 2118788-2 the primary substitute for ongoing production and design requirements. The substitute part is currently active and maintains compatibility across critical mechanical and electrical parameters.

Key Considerations:

The 2118788-2 differs from the main part in antenna construction type (chip versus stamped metal) and does not provide specified gain and VSWR values. Both components support dual-band operation across 2.4GHz and 5GHz frequency ranges with identical surface mount solder termination and compatible physical dimensions.

The substitute part carries ROHS3 compliance certification, whereas the main part status is not applicable. Both components maintain EAR99 export classification and MSL 1 moisture sensitivity rating.

Selection of the 2118788-2 is appropriate for applications requiring dual-band RF antenna functionality with surface mount integration and solder termination in compact form factors.

Frequently Asked Questions (FAQ)

Q: Can the 2118788-2 directly replace the 2118315-2 in existing designs?

A: The 2118788-2 provides dual-band RF antenna functionality with compatible surface mount solder termination and physical dimensions. However, the antenna construction differs (chip versus stamped metal), and the substitute part does not provide specified gain and VSWR parameters. Design validation is necessary to confirm performance requirements.

Q: What are the primary differences between these two antenna types?

A: The 2118315-2 uses stamped metal construction with specified 4.3dBi gain and 2.5 VSWR. The 2118788-2 uses chip antenna construction with unspecified gain and VSWR characteristics. Both support dual-band operation and surface mount solder termination.

Q: Are there packaging differences between these parts?

A: The 2118315-2 packaging is not specified. The 2118788-2 is supplied in tray packaging. Both components maintain identical moisture sensitivity level MSL 1 (Unlimited) and compatible physical height specifications.

Q: What is the significance of the product status difference?

A: The 2118315-2 is obsolete, indicating discontinued production and limited availability. The 2118788-2 is active, ensuring ongoing supply and manufacturing support for production requirements.

Q: Do both parts meet current compliance requirements?

A: The 2118788-2 carries ROHS3 compliance certification. The 2118315-2 RoHS status is not applicable. Both components maintain EAR99 export classification and are suitable for applications requiring dual-band wireless connectivity.
