Key Parameters

Substitute Part Grouping Explanation

Substitution of the M310210 is based on strict electrical and mechanical parameter matching within the Savvi series antenna family. The following parameters determine substitution eligibility:

• Frequency range: 2.4GHz ~ 2.5GHz (exact match required)
• Antenna type: Chip (exact match required)
• Gain: -1.3dB (exact match required)
• VSWR: 1.02 (exact match required)
• Mounting type: Surface Mount (exact match required)
• Height (Max): 0.043" (1.08mm) (exact match required)
• Termination: Solder (exact match required)
• RF Family/Standard: 802.15.4, Bluetooth, WiFi (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The M310210 is directly substitutable with M310220, which maintains identical electrical performance and mechanical specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The M310220 is the direct substitute for the M310210. Both components are manufactured by Ethertronics/AVX within the Savvi series and maintain identical electrical and mechanical specifications. The primary distinction is product status: M310210 is obsolete while M310220 is active. M310220 offers RoHS compliance certification and significantly higher inventory availability (4255 units versus 854 units), making it the preferred selection for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can M310220 be used as a direct replacement for M310210 in existing designs?

A: Yes. M310220 is electrically and mechanically identical to M310210. All critical parameters including frequency range, gain, VSWR, mounting type, and physical dimensions are matched. No circuit modifications are required.

Q: What is the difference between M310210 and M310220?

A: The primary differences are product status and packaging. M310210 is obsolete; M310220 is active. M310220 is supplied in Tape & Reel (TR) packaging and carries RoHS compliance certification. Electrical and mechanical performance are identical.

Q: Are there any compatibility concerns when substituting M310220 for M310210?

A: No compatibility concerns exist. Both components share identical RF performance characteristics, physical dimensions, and termination methods. PCB layout and design considerations remain unchanged.

Q: Why is M310210 listed as obsolete?

A: M310210 has been superseded by M310220 within the Savvi antenna product line. M310220 provides the same functionality with active manufacturing status and improved supply chain availability.

Q: Does packaging type affect electrical performance?

A: No. Tape & Reel (TR) packaging used for M310220 is a supply format only and does not affect the electrical or mechanical characteristics of the antenna component itself.
