M620710 RF Antenna 915MHz Chip Equivalent & Substitute Parts

Part Overview

The M620710 is a 915MHz ISM band chip RF antenna manufactured by Ethertronics/AVX under the Savvi™ series. This surface mount component is designed for ISM, LoRa, LPWAN, and Sigfox applications operating in the 902MHz to 928MHz frequency range. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations requiring equivalent performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M620710 is determined by the following critical parameters:

• Frequency coverage: The substitute must support the 902MHz to 928MHz band required for 915MHz ISM applications
• Antenna type: Chip antenna configuration
• Gain specification: 2.56dB minimum performance
• VSWR: 2.6 or better
• Mounting type: Surface mount with identical physical dimensions (0.043" maximum height)
• Termination method: Solder connection
• Moisture sensitivity: MSL 1 rating
• Series compatibility: Savvi™ series components

The M620720 qualifies as a direct substitute based on these parameters. It maintains identical electrical performance characteristics, physical dimensions, and termination specifications while extending frequency coverage to include the 868MHz band.

Parameter Comparison

Engineering Selection Recommendations

The M620720 is the direct equivalent substitute for the obsolete M620710. Selection is based on the following engineering criteria:

• All critical electrical parameters are identical: gain, VSWR, frequency response within the 902MHz to 928MHz band, and impedance termination
• Physical dimensions and mounting characteristics are unchanged, ensuring PCB layout compatibility without redesign
• The M620720 maintains MSL 1 rating, confirming equivalent moisture handling and storage requirements
• The M620720 is actively manufactured with RoHS compliance certification, providing supply chain continuity and regulatory alignment
• Extended frequency coverage to 868MHz in the M620720 does not compromise 915MHz performance and enables broader application flexibility

No design modifications are required for direct substitution of M620710 with M620720 in existing circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can M620720 be used as a direct replacement for M620710 in production designs?

A: Yes. The M620720 provides identical electrical performance across all specified parameters for 915MHz ISM band operation. Physical dimensions, mounting type, and termination method are unchanged. Direct PCB substitution is possible without circuit modification.

Q: What is the primary advantage of using M620720 over M620710?

A: The M620720 is actively manufactured, whereas M620710 is obsolete. M620720 also carries RoHS compliance certification and extends frequency coverage to include the 868MHz band, providing supply chain security and regulatory compliance for new designs.

Q: Are there packaging differences between M620710 and M620720?

A: M620710 packaging is not specified in the available data. M620720 is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement process.

Q: Do the frequency ranges overlap sufficiently for 915MHz applications?

A: Yes. Both parts cover the 902MHz to 928MHz band required for 915MHz ISM applications. The M620720 adds 868MHz to 870MHz coverage without affecting 915MHz performance.

Q: What is the moisture sensitivity rating for both parts?

A: Both M620710 and M620720 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Is RoHS compliance a factor in substitution?

A: M620720 is RoHS compliant. If your application requires RoHS certification, M620720 meets this requirement. M620710 RoHS status is not specified.
