Key Parameters

Substitute Part Grouping Explanation

The RF55-31F-T-02-50-X-SH qualifies as a parametric equivalent to the RF55-27F-T-02-50-A-SH based on the following critical parameters:

• Connector Style: Both are SMB, Fakra connectors
• Connector Type: Both are Plug, Male Pin configurations
• Impedance: Both maintain 50 ohms
• Mounting Type: Both are Free Hanging (In-Line)
• Contact Termination: Both use Crimp termination
• Shield Termination: Both use Crimp termination
• Frequency - Max: Both rated to 4 GHz
• Cable Group: Both support RG-174 and RG-316
• Operating Temperature: Both operate -40°C ~ 85°C
• Fastening Type: Both use Locking Ramp
• Housing Color: Both Brown
• Center Contact Material: Both Brass
• Body Material: Both Brass
• Body Finish: Both Nickel
• Center Contact Plating: Both Gold
• Dielectric Material: Both PTFE
• RoHS Status: Both ROHS3 Compliant
• MSL: Both Level 1 (Unlimited)

The primary difference lies in the base product number designation (RF55-27 versus RF55-31), which reflects internal manufacturer design variants that do not affect electrical or mechanical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the RF55-27F-T-02-50-A-SH and RF55-31F-T-02-50-X-SH are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and lead time requirements. The RF55-27F-T-02-50-A-SH maintains higher stock levels at 1,165 units, while the RF55-31F-T-02-50-X-SH provides an alternative with 838 units available. Both parts meet identical electrical and mechanical specifications for SMB Fakra connector plug applications requiring 50 ohm impedance, free-hanging crimp termination, and operation across the -40°C to 85°C temperature range.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts maintain identical electrical and mechanical parameters including connector style, impedance, termination method, frequency rating, and operating temperature range. The base product number difference does not affect functional compatibility.

Q: What determines substitution eligibility for SMB Fakra connectors?

A: Substitution is valid when the following parameters match: connector style (SMB, Fakra), connector type (Plug, Male Pin), impedance (50 ohms), mounting type (Free Hanging In-Line), contact and shield termination methods (Crimp), frequency rating (4 GHz), cable group compatibility (RG-174, 316), and operating temperature range (-40°C ~ 85°C).

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of Level 1 (Unlimited). Both are active production parts with equivalent regulatory status.

Q: What is the difference between the RF55-27 and RF55-31 base product numbers?

A: The base product number designates internal manufacturer design variants. These variants do not affect electrical performance, mechanical fit, or functional compatibility within the specified parameter set for this connector category.

Q: Which part should be selected based on availability?

A: Selection should be based on current inventory and delivery requirements. The RF55-27F-T-02-50-A-SH has 1,165 units in stock, while the RF55-31F-T-02-50-X-SH has 838 units available. Both are active production parts with equivalent lead times.
