RF55-27C-T-02-50-A-SH Equivalent & Substitute Parts

Part Overview

The RF55-27C-T-02-50-A-SH is an SMB Fakra connector plug manufactured by Adam Tech, designed for 50-ohm coaxial applications. This male pin connector features crimp termination for both contact and shield, with free-hanging (in-line) mounting suitable for RG-174 and RG-316 cable groups. The connector operates across a frequency range up to 4 GHz and maintains performance across the industrial temperature range of -40°C to 85°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Identifying equivalent substitute parts is essential for supply chain continuity, inventory optimization, and ensuring design flexibility across manufacturing cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RF55-27C-T-02-50-A-SH is determined by strict equivalence across the following critical parameters:

• Connector style and type (SMB, Fakra plug with male pin configuration)
• Electrical impedance (50 Ohms)
• Termination method (crimp for both contact and shield)
• Mounting configuration (free hanging, in-line)
• Compatible cable groups (RG-174, RG-316)
• Maximum frequency rating (4 GHz minimum)
• Operating temperature range (-40°C to 85°C minimum)
• Material composition and finish specifications
• Regulatory compliance (ROHS3, REACH Unaffected)

The substitute part RF55-31C-T-02-50-X-SH meets all these criteria and is therefore classified as a parametric equivalent. The difference in base product number (RF55-31 versus RF55-27) reflects manufacturing or design revision variations that do not affect functional interchangeability within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both RF55-27C-T-02-50-A-SH and RF55-31C-T-02-50-X-SH are active production parts with identical regulatory compliance profiles. Both carry ROHS3 certification and REACH Unaffected status, meeting current environmental and hazardous substance directives. The RF55-31C-T-02-50-X-SH offers higher current inventory availability (1690 pcs versus 857 pcs), which may provide supply chain advantages for high-volume applications or extended lead-time mitigation. Selection between these parts should be based on inventory availability, procurement timelines, and existing design documentation requirements. No functional or performance differentiation exists between the two parts within the specified electrical and mechanical operating parameters.

Frequently Asked Questions (FAQ)

Q: Are RF55-27C-T-02-50-A-SH and RF55-31C-T-02-50-X-SH electrically interchangeable?

A: Yes. Both parts meet identical electrical specifications including 50-ohm impedance, 4 GHz maximum frequency, crimp termination, and PTFE dielectric material. They are suitable for direct substitution in applications designed for either part number.

Q: What is the significance of the different base product numbers (RF55-27 versus RF55-31)?

A: The base product number difference reflects manufacturing or design revision variations within Adam Tech's product line. These variations do not affect functional interchangeability when all other parameters remain identical.

Q: Can these connectors be used with cable groups other than RG-174 and RG-316?

A: No. These connectors are specified for RG-174 and RG-316 cable groups only. Use with other cable types is outside the validated parameter set.

Q: What is the maximum operating frequency for these connectors?

A: Both parts are rated to 4 GHz maximum frequency. Applications requiring higher frequency performance require alternative connector designs.

Q: Are these parts suitable for outdoor or high-humidity environments?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. The operating temperature range of -40°C to 85°C supports industrial and outdoor deployment within this temperature envelope.

Q: What termination method is required for these connectors?

A: Both contact and shield termination use crimp methodology. Soldering or other termination methods are not applicable to these connector designs.

Q: Do these parts require any special handling or storage conditions?

A: Both parts carry MSL 1 (Unlimited) rating, indicating standard handling and storage conditions are appropriate. No special moisture-barrier packaging or baking procedures are required.
