Substitute Part Grouping Explanation
Substitute parts for the 901-9201-1ASF are classified into three categories based on parametric equivalence and application compatibility:
Parametric Equivalents (Amphenol RF Manufacturer): Parts 901-9201-1A and 901-9868-RFX maintain identical electrical specifications including 50 ohm impedance, 18 GHz maximum frequency, solder termination, and RG-402 cable compatibility. These parts differ in packaging format (bulk versus tape and reel) and material composition. The 901-9201-1A uses beryllium copper center contacts with stainless steel body, while 901-9868-RFX uses brass center contacts with brass body. Both maintain ROHS3 compliance and unlimited moisture sensitivity rating.
Direct Manufacturer Equivalents (TE Connectivity): Part 1-1478903-0 provides full electrical and mechanical compatibility with identical impedance, frequency rating, solder termination, and RG-402 cable group specifications. This part includes connector, contact, and insulator components and carries RoHS compliance (non-ROHS3). Part 1050524-1 matches all electrical parameters but operates at reduced maximum temperature (-65°C to 125°C versus 165°C).
Obsolete Direct Equivalents (TE Connectivity): Parts 1056227-1 and 1056232-1 are classified as obsolete but maintain core electrical compatibility. Part 1056227-1 supports extended frequency operation to 27 GHz with beryllium copper contacts. Part 1056232-1 is configured for RG-405 cable (.085" semi-rigid) with reduced operating temperature range (-65°C to 105°C) and lower voltage rating (335 V).
Similar Alternatives (Cinch Connectivity Solutions): Parts 142-0693-001, 142-0693-006, 142-0694-011, and 142-0694-016 provide functional SMA plug configurations with 50 ohm impedance and threaded fastening. These parts are configured for RG-405 cable group (.086" semi-rigid) rather than RG-402, operate at reduced maximum frequency (18 to 26.5 GHz), and feature brass body construction with nickel or gold finish options. Parts 142-0694-011 and 142-0694-016 do not specify contact termination method and include coupling nut rather than full component sets.
Substitution Criteria: All listed parts maintain SMA connector style, male pin configuration, 50 ohm impedance, threaded fastening, and free hanging mounting. Electrical compatibility is determined by matching impedance, frequency rating, and termination specifications. Mechanical compatibility requires verification of cable group compatibility and body material properties. Compliance status varies between ROHS3, RoHS, and REACH affected designations.

Q: Can Cinch Connectivity 142-0693-001 replace the Amphenol RF 901-9201-1ASF?
A: Part 142-0693-001 is not a direct replacement. While both parts maintain 50 ohm impedance and solder termination, the Cinch part is configured for RG-405 cable group (.086" semi-rigid) rather than RG-402 (.141" semi-rigid). This cable group difference creates mechanical incompatibility. The Cinch part also operates at 26.5 GHz maximum frequency and uses brass body construction. Selection of this part requires cable reconfiguration and verification of application compatibility.
Q: What is the significance of the contact termination specification?
A: Contact termination specifies the method for connecting the center conductor to the connector. The 901-9201-1ASF uses solder termination for both center contact and shield. Parts 142-0694-011 and 142-0694-016 do not specify contact termination method, which may indicate alternative termination approaches. Verification of termination compatibility with application requirements is necessary before substitution.
Q: Are all listed substitute parts ROHS3 compliant?
A: No. Parts 1-1478903-0 and 1056227-1 carry RoHS compliance designation without ROHS3 specification. The remaining parts including 901-9201-1ASF, 901-9201-1A, 901-9868-RFX, 1050524-1, 1056232-1, 142-0693-001, 142-0693-006, 142-0694-011, and 142-0694-016 are ROHS3 compliant.
