Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 252153 are identified based on strict equivalence of the following critical parameters:

Electrical Parameters:

• Impedance: 50 Ohms
• Frequency - Max: 6 GHz
• Connector Style: MCX

Mechanical Parameters:

• Mounting Type: Through Hole
• Contact Termination: Solder
• Shield Termination: Solder
• Fastening Type: Snap-On
• Number of Ports: 1

Material & Environmental Parameters:

• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Body Material: Brass
• Body Finish: Gold
• Center Contact Material: Brass
• Center Contact Plating: Gold
• Mating Cycles: 500
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The Cinch Connectivity Solutions 133-3801-201 meets all critical substitution criteria within the MCX coaxial connector category. The primary functional difference is the connector type designation (Plug vs. Receptacle), which represents a complementary mating interface rather than a functional incompatibility in RF circuit applications where both connector types are required for complete signal transmission paths.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 252153 and Cinch Connectivity Solutions 133-3801-201 are active production components with ROHS3 compliance and REACH affected status. Selection between these parts is determined by circuit application requirements and connector interface specifications.

The Amphenol RF 252153 (Receptacle, Male Pin) is selected for applications requiring the female mating interface. The Cinch Connectivity Solutions 133-3801-201 (Plug, Male Pin) is selected for applications requiring the male mating interface. Both components operate identically within the 50 Ohm, 6 GHz RF specification envelope and share equivalent material composition, termination methods, and environmental ratings.

The Cinch part provides higher voltage rating (335 V vs. 225 V) and greater inventory availability (20262 pcs vs. 976 pcs). The Amphenol part specifies insertion loss at 0.1 dB. Both parts maintain 500 mating cycles and unlimited moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the Cinch Connectivity Solutions 133-3801-201 directly replace the Amphenol RF 252153 in my circuit?

A: Direct replacement depends on connector interface requirements. The Amphenol part is a Receptacle (female interface), while the Cinch part is a Plug (male interface). Both are MCX connectors with identical electrical specifications (50 Ohms, 6 GHz). If your circuit requires a female receptacle interface, the Amphenol part is the correct selection. If your circuit requires a male plug interface, the Cinch part is the correct selection. These parts are complementary mating components, not direct substitutes for the same circuit position.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by: Connector Style (MCX), Impedance (50 Ohms), and Frequency - Max (6 GHz). All substitute parts must maintain these three parameters to ensure RF signal integrity and circuit compatibility.

Q: Are there differences in mechanical mounting between these parts?

A: Both parts use Through Hole mounting with Solder termination and Snap-On fastening. Mechanical mounting is equivalent. Packaging differs (Amphenol: Bag; Cinch: Bulk), which affects inventory handling but not functional performance.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 Compliant, REACH Affected, and classified under ECCN EAR99 with HTSUS code 8536.69.4010. Compliance status is equivalent.

Q: What is the difference in voltage rating between these parts?

A: The Amphenol RF 252153 is rated at 225 V, while the Cinch Connectivity Solutions 133-3801-201 is rated at 335 V. For applications requiring voltage ratings above 225 V, the Cinch part provides higher margin. For applications operating below 225 V, both parts are suitable.

Q: Is insertion loss a critical parameter for substitution?

A: The Amphenol part specifies 0.1 dB insertion loss. The Cinch part does not provide insertion loss specification in the available data. For applications where insertion loss specification is critical, the Amphenol part provides documented performance. For general RF applications within the 6 GHz frequency range, both parts operate within MCX connector performance standards.

Q: What is the inventory availability difference?

A: Amphenol RF 252153 has 976 pieces in stock. Cinch Connectivity Solutions 133-3801-201 has 20262 pieces in stock. The Cinch part offers significantly higher inventory availability for high-volume applications.
