Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 901-9201-2ASF is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Connector Style: SMA (mandatory match)
• Connector Type: Plug, Male Pin (mandatory match)
• Impedance: 50 Ohms (mandatory match)
• Contact Termination: Solder (mandatory match)
• Shield Termination: Solder (mandatory match)
• Mounting Type: Free Hanging (In-Line) (mandatory match)
• Fastening Type: Threaded (mandatory match)
• Number of Ports: 1 (mandatory match)

Secondary Compatibility Parameters:

• Cable Group: RG-405 semi-rigid cable compatibility
• Frequency - Max: 18 GHz or higher
• Operating Temperature: -65°C minimum and 165°C maximum
• Mating Cycles: 500 or greater
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts are classified as Direct Substitutes when all primary criteria and cable group specifications align. Parts are classified as Similar when cable group differs (RG-402 instead of RG-405) or when contact termination specifications vary, requiring engineering evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Primary Selection):

1050548-1 (TE Connectivity AMP Connectors) qualifies as a direct substitute for applications operating within -65°C to 105°C temperature range. This part maintains all primary substitution criteria including SMA connector style, male pin configuration, 50-ohm impedance, solder termination for both contact and shield, RG-405 cable compatibility, and 500 mating cycles. Active product status and ROHS3 compliance ensure long-term availability and regulatory alignment. Selection of this part is appropriate when thermal environment does not exceed 105°C maximum operating temperature.

142-0693-001 (Cinch Connectivity Solutions Johnson) and 142-0693-006 (Cinch Connectivity Solutions) both qualify as direct substitutes with full temperature range compatibility (-65°C to 165°C) matching the original specification. Both parts maintain SMA connector style, male pin configuration, 50-ohm impedance, solder termination, RG-405 cable group compatibility, and 500 mating cycles. Both are Active products with ROHS3 compliance. The distinction between these parts is housing color: 142-0693-001 features gold finish while 142-0693-006 features nickel finish. Selection between these parts depends on application-specific finish requirements.

Obsolete Status Consideration:

1056232-1 (TE Connectivity AMP Connectors) carries Obsolete product status despite meeting all primary substitution criteria. This part supports 27 GHz frequency performance and maintains RG-405 cable compatibility with 500 mating cycles. However, the Obsolete designation indicates discontinued manufacturing and limited future availability. This part is suitable only for replacement applications where existing inventory exists or when frequency performance exceeding 18 GHz is required and no Active alternative is available.

Limited Compatibility Parts:

142-0694-016 (Cinch Connectivity Solutions) presents a cable group incompatibility, supporting RG-402 (.141" semi-rigid) cable instead of RG-405. Additionally, this part specifies only 100 mating cycles compared to the 500-cycle rating of the original part. Contact termination is not specified. This part is suitable only when RG-402 cable compatibility is required and reduced mating cycle tolerance is acceptable.

1056227-1 (TE Connectivity AMP Connectors) is classified as Similar due to RG-402 cable group incompatibility and Obsolete product status. This part is not recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1050548-1 for 901-9201-2ASF in all applications?

A: The 1050548-1 is a direct substitute for applications with maximum operating temperature of 105°C. If your application requires operation at temperatures above 105°C up to 165°C, use 142-0693-001 or 142-0693-006 instead. All three parts maintain identical SMA connector style, 50-ohm impedance, solder termination, and RG-405 cable compatibility.

Q: What is the difference between 142-0693-001 and 142-0693-006?

A: Both parts are functionally equivalent direct substitutes for the 901-9201-2ASF. The primary difference is housing finish: 142-0693-001 features gold body finish while 142-0693-006 features nickel body finish. Both support the full -65°C to 165°C operating temperature range and maintain all electrical specifications. Selection depends on application-specific finish requirements or environmental corrosion considerations.

Q: Why is 1056232-1 marked as Obsolete?

A: The 1056232-1 carries Obsolete product status, indicating the manufacturer has discontinued production. While this part meets all primary substitution criteria and supports higher frequency performance (27 GHz), its Obsolete status means limited future availability and potential supply chain constraints. For new designs, select from Active status alternatives: 1050548-1, 142-0693-001, or 142-0693-006.

Q: Can I use 142-0694-016 as a substitute?

A: The 142-0694-016 is not a direct substitute due to cable group incompatibility. This part is designed for RG-402 (.141" semi-rigid) cable, while the 901-9201-2ASF is specified for RG-405 (.085" to .086" semi-rigid) cable. Additionally, 142-0694-016 supports only 100 mating cycles compared to 500 cycles for the original part. Use this part only when RG-402 cable compatibility is specifically required.

Q: What does ROHS3 compliance mean for my application?

A: ROHS3 compliance indicates the connector meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All substitute parts listed carry ROHS3 compliance, ensuring regulatory alignment for applications subject to EU environmental directives or equivalent standards.

Q: Are all substitute parts rated for 500 mating cycles?

A: No. Most direct substitutes (1050548-1, 1056232-1, 142-0693-001, 142-0693-006) are rated for 500 mating cycles matching the original specification. However, 142-0694-016 is rated for only 100 mating cycles. For applications requiring 500 mating cycle durability, avoid 142-0694-016.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All listed substitute parts carry MSL 1 rating, meaning they do not require special dry storage or handling procedures and maintain full performance characteristics regardless of storage duration.

Q: Can I use these connectors interchangeably in existing assemblies?

A: Direct substitutes (1050548-1, 142-0693-001, 142-0693-006) maintain identical SMA connector geometry, threaded fastening, and solder termination, allowing mechanical and electrical interchangeability in existing assemblies. However, verify operating temperature requirements: if your assembly operates above 105°C, do not use 1050548-1. For RG-402 cable applications, 142-0694-016 is mechanically compatible but requires cable group verification.
