The RF55-31I-T-02-50-X-SH currently maintains higher inventory levels (1118 Pcs) compared to the RF55-27I-T-02-50-A-SH (675 Pcs), which may influence procurement decisions for high-volume applications. Both parts are suitable for direct substitution in 50 Ohm RF circuits operating within the -40°C to 85°C temperature range and supporting frequencies up to 4 GHz.

Frequently Asked Questions (FAQ)

Q: Can RF55-31I-T-02-50-X-SH be used as a direct replacement for RF55-27I-T-02-50-A-SH?

A: Yes. Both connectors maintain identical electrical specifications (50 Ohm impedance, 4 GHz maximum frequency), mechanical configuration (SMB Fakra plug with crimp termination), and environmental ratings (-40°C to 85°C operating temperature). Physical interchangeability is confirmed across all provided parameters.

Q: Are there differences in cable compatibility between these parts?

A: No. Both connectors support the same cable groups: RG-174 and RG-316. Crimp termination specifications are identical for both contact and shield connections.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both RF55-27I-T-02-50-A-SH and RF55-31I-T-02-50-X-SH are ROHS3 compliant and REACH unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity level classification.

Q: What is the difference between these part numbers?

A: The part numbers differ in the base product designation (RF55-27 versus RF55-31) and a single character in the configuration code (A versus X). These designations reflect internal Adam Tech product line organization but do not indicate functional or electrical differences based on the provided specifications.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supply chain lead times. Both parts are Active status and suitable for new applications. The RF55-31I-T-02-50-X-SH offers higher inventory availability (1118 Pcs versus 675 Pcs).
