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

Part Overview

The RF55-27L-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, supporting RG-174 and RG-316 cable groups with a maximum frequency rating of 4 GHz. The connector is housed in red carmine with nickel-plated brass body and gold-plated center contact, operating across -40°C to 85°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level rating.

Substitute parts become necessary when the primary part number experiences supply constraints, extended lead times, or inventory depletion while maintaining identical electrical and mechanical performance requirements.

Key Parameters

Substitute Part Grouping Explanation

The RF55-31L-T-02-50-X-SH qualifies as a parametric equivalent based on matching all critical electrical and mechanical parameters that define functional interchangeability for SMB Fakra connectors in 50 Ohm systems.

Substitution is valid when the following parameters are identical:

• Connector style (SMB, Fakra)
• Connector type (Plug, Male Pin)
• Impedance (50 Ohms)
• Contact and shield termination method (Crimp)
• Mounting configuration (Free Hanging In-Line)
• Compatible cable groups (RG-174, RG-316)
• Maximum frequency rating (4 GHz)
• Operating temperature range (-40°C to 85°C)
• Dielectric material (PTFE)
• Compliance certifications (ROHS3)

The difference between RF55-27L-T-02-50-A-SH and RF55-31L-T-02-50-X-SH exists only in the base product number designation (RF55-27 versus RF55-31), which reflects internal manufacturer product line segmentation without affecting electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both RF55-27L-T-02-50-A-SH and RF55-31L-T-02-50-X-SH are active production parts with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and lead time requirements, as all electrical and mechanical parameters are equivalent.

RF55-27L-T-02-50-A-SH currently maintains higher inventory (1134 pieces) compared to RF55-31L-T-02-50-X-SH (816 pieces). Both parts carry unlimited moisture sensitivity level rating and are suitable for immediate deployment in 50 Ohm coaxial applications requiring SMB Fakra male pin connectors with crimp termination.

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors are electrically and mechanically identical across all specified parameters including impedance, frequency rating, termination method, cable compatibility, and operating temperature range. The difference in base product number does not affect functional performance.
