All identified substitute parts maintain the core electrical and mechanical specifications required for direct functional replacement in 50-ohm SMA solder applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Equivalent (Amphenol RF 132101): The 132101 is a parametric equivalent manufactured by Amphenol RF with identical electrical and mechanical specifications to the 901-9201-2A. The primary difference is packaging format (Bag vs. Bulk). Both parts are ROHS3 compliant and active in product status. The 132101 offers higher inventory availability (3135 pieces) and is suitable for direct substitution in all applications where the 901-9201-2A is specified.

Active Alternatives (TE Connectivity 1050547-1): The TE Connectivity 1050547-1 maintains full electrical compatibility with identical impedance, frequency response, and solder termination specifications. This part is ROHS3 compliant and currently active. The operating temperature range is limited to -65°C to 105°C, which restricts use in applications requiring the full -65°C to 165°C range of the 901-9201-2A. Selection of this part is appropriate for applications operating within the -65°C to 105°C envelope.

Extended Frequency Alternative (Cinch Connectivity Solutions 142-0693-001): The 142-0693-001 provides identical core specifications with extended frequency performance to 26.5 GHz, exceeding the 18 GHz maximum of the 901-9201-2A. This part maintains full operating temperature range (-65°C to 165°C) and is ROHS3 compliant. The 142-0693-001 is suitable for applications requiring higher frequency capability while maintaining all other electrical and mechanical parameters.

Obsolete Status (TE Connectivity 1050770-1): The 1050770-1 is designated as obsolete product status. While inventory is available (1196 pieces), this part should be selected only when existing designs or legacy systems specifically require this part number. The operating temperature range is limited to -65°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 132101 be used as a direct replacement for the 901-9201-2A?

A: Yes. The 132101 is a parametric equivalent with identical electrical specifications (50 ohms, SMA plug, solder termination, 18 GHz maximum frequency) and mechanical configuration (free-hanging, RG-405 cable compatibility). The only difference is packaging format (Bag vs. Bulk). Both parts are ROHS3 compliant and active in product status.

Q: What is the primary limitation of the TE Connectivity 1050547-1 compared to the 901-9201-2A?

A: The 1050547-1 has a reduced operating temperature maximum of 105°C, compared to 165°C for the 901-9201-2A. All other electrical and mechanical specifications are identical. This part is suitable only for applications operating within the -65°C to 105°C range.

Q: Does the Cinch 142-0693-001 offer any performance advantages?

A: The 142-0693-001 extends the maximum frequency specification to 26.5 GHz, compared to 18 GHz for the 901-9201-2A. All other specifications remain equivalent, including the full operating temperature range (-65°C to 165°C). This part is suitable for applications requiring higher frequency performance.

Q: Why is the TE Connectivity 1050770-1 marked as obsolete?

A: The 1050770-1 is designated obsolete product status by the manufacturer. While inventory remains available, this part should be selected only for legacy system support or when existing designs specifically require this part number. For new designs, the active alternatives (132101, 1050547-1, or 142-0693-001) are recommended.

Q: Are all substitute parts ROHS3 compliant?

A: The 901-9201-2A, 132101, 1050547-1, and 142-0693-001 are all ROHS3 compliant. The 1050770-1 is RoHS compliant but not specifically ROHS3 certified. Compliance requirements should be verified against application specifications.

Q: What is the difference between center contact materials (Beryllium Copper vs. Brass)?

A: Both Beryllium Copper and Brass are acceptable center contact materials for 50-ohm SMA solder connectors. The 901-9201-2A and 1050547-1 use Beryllium Copper, while 132101 and 142-0693-001 use Brass. Material selection does not affect electrical performance within the specified parameters.

Q: Can packaging format (Bulk vs. Bag) affect connector performance?

A: No. Packaging format (Bulk vs. Bag) is a logistics and handling consideration only. It does not affect electrical performance, mechanical compatibility, or functional specifications. The 901-9201-2A (Bulk) and 132101 (Bag) are functionally identical.

Q: Which substitute part offers the best overall compatibility?

A: The Amphenol RF 132101 offers the best overall compatibility as a parametric equivalent. It maintains all electrical and mechanical specifications of the 901-9201-2A, is ROHS3 compliant, active in product status, and offers higher inventory availability.
