Engineering Selection Recommendations
Primary Substitute: Amphenol RF 908-22116
The 908-22116 is the direct equivalent from the same manufacturer. It shares identical electrical specifications, operating temperature range, and material composition with the main part 908-22109. Both parts are ROHS3 compliant and currently active in production. The 908-22116 offers higher inventory availability (1590 units) compared to the main part. This substitute is suitable for direct replacement without design modification.
Secondary Substitutes: Cinch 135-3711-201 and Lighthorse MCSF66GT-T/R
Both parts meet all critical electrical and mechanical parameters. The Cinch 135-3711-201 and Lighthorse MCSF66GT-T/R operate within a narrower temperature range (-55°C ~ 155°C and -65°C ~ 165°C respectively) compared to the main part's -65°C ~ 165°C specification. The Lighthorse part maintains the full temperature range of the original. Both are ROHS3 compliant and active in production. Selection between these options depends on application temperature requirements and supply chain preferences.
Alternative Substitute: Huber+Suhner 82_MMCX-50-0-8/111_OE
The Huber+Suhner 82_MMCX-50-0-8/111_OE meets all critical electrical and mechanical parameters with operating temperature range of -55°C ~ 155°C. This part features dielectric material composition of PFA and PTFE. It is ROHS3 compliant and currently active in production with 3133 units in stock. This substitute is suitable for applications within the specified temperature range.
Not Recommended: Huber+Suhner 84021269
The 84021269 is classified as obsolete and should not be selected for new designs or production applications. While it meets the core electrical and mechanical parameters, its obsolete status, narrower operating temperature range (-40°C ~ 90°C), and different center contact material (Bronze instead of Beryllium Copper) make it unsuitable for substitution.
Frequently Asked Questions (FAQ)
Q: Can the Amphenol RF 908-22116 be used as a direct replacement for the 908-22109?
A: Yes. Both parts are manufactured by Amphenol RF and share identical electrical specifications, impedance, frequency range, operating temperature, and material composition. The 908-22116 is a direct equivalent suitable for immediate substitution.
Q: What is the difference between the Cinch 135-3711-201 and the main part 908-22109?
A: The Cinch 135-3711-201 meets all critical electrical and mechanical parameters. The primary difference is the operating temperature range: the Cinch part operates from -55°C to 155°C, while the main part operates from -65°C to 165°C. For applications within the Cinch temperature range, this part is fully compatible.
Q: Are all substitute parts ROHS3 compliant?
A: All active substitute parts listed (908-22116, 135-3711-201, 82_MMCX-50-0-8/111_OE, and MCSF66GT-T/R) are ROHS3 compliant. The obsolete part 84021269 is also ROHS3 compliant but is not recommended for new applications.
Q: What is the difference between the Lighthorse MCSF66GT-T/R and the main part?
A: The Lighthorse MCSF66GT-T/R is electrically and mechanically equivalent to the main part. It maintains the same operating temperature range (-65°C ~ 165°C), impedance, frequency response, and material specifications. The primary difference is packaging format (Tape & Reel versus Bulk).
Q: Why is the Huber+Suhner 84021269 marked as obsolete?
A: The 84021269 is classified as obsolete and should not be used for new designs. Obsolete parts have been discontinued by the manufacturer and are no longer supported for production applications.
Q: Can I use the Huber+Suhner 82_MMCX-50-0-8/111_OE in place of the 908-22109?
A: The 82_MMCX-50-0-8/111_OE meets all critical electrical and mechanical parameters and is suitable for substitution. However, its operating temperature range is -55°C to 155°C, which is narrower than the main part's -65°C to 165°C range. Verify that your application does not require operation below -55°C or above 155°C before selecting this substitute.
Q: What inventory levels are available for each substitute part?
A: Current inventory levels are as follows: 908-22116 (1590 units), 135-3711-201 (3410 units), 82_MMCX-50-0-8/111_OE (3133 units), and MCSF66GT-T/R (8078 units). The main part 908-22109 has 815 units in stock.
Q: Are there any differences in dielectric material between the substitute parts?
A: Most substitute parts use PTFE dielectric material. The Huber+Suhner 82_MMCX-50-0-8/111_OE uses a combination of PFA and PTFE. Both material compositions are suitable for 50-ohm RF applications up to 6 GHz.
Q: What is the significance of the 500 mating cycles specification?
A: The 500 mating cycles specification indicates the connector's mechanical durability rating. All listed parts, including the main part and all active substitutes, share this specification, confirming equivalent mechanical reliability for connection and disconnection operations.
