Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity AMP Connectors 1050542-1 are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Primary Matching Parameters:

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line)
• Cable Group: RG-402 (.141" Semi Rigid)
• Fastening Type: Threaded
• Frequency - Max: 18 GHz
• Number of Ports: 1
• Shield Termination: Solder

Secondary Compatibility Parameters:

• Operating Temperature Range (minimum -65°C, maximum ≥105°C)
• Voltage Rating: 335 V
• Mating Cycles: ≥500
• Body Finish: Gold
• RoHS Compliance Status

Substitute parts must satisfy all primary matching parameters. Variations in secondary parameters such as body material composition, center contact material, or dielectric material do not preclude substitution when primary electrical and mechanical specifications are met.

Engineering Selection Recommendations

Amphenol RF 901-9201-1ASF

The Amphenol RF 901-9201-1ASF is an active product that satisfies all primary electrical and mechanical parameters required for substitution. This connector provides an extended operating temperature range (-65°C ~ 165°C) compared to the original part, offering enhanced thermal performance for demanding applications. The part carries ROHS3 compliance certification and REACH affected status, meeting current regulatory requirements. With 500 mating cycles and stainless steel construction with gold finish, this substitute maintains mechanical durability equivalent to the original specification.

Cinch Connectivity Solutions Johnson 142-0694-021

The Cinch Connectivity Solutions Johnson 142-0694-021 is an active product that meets all primary electrical and mechanical parameters. This connector features an extended operating temperature range (-65°C ~ 165°C) and maintains the 335 V voltage rating of the original part. RoHS compliance is confirmed. The part includes 2 pieces (1 connector and 1 coupling nut) in bulk packaging. Note that the mating cycle rating is 100 cycles, which is lower than the original specification of 500 cycles. Body material is brass rather than stainless steel. These differences do not preclude substitution for applications where the lower cycle rating and alternative body material are acceptable.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the TE Connectivity AMP Connectors 1050542-1?

A: A substitute part must match all primary electrical and mechanical parameters: SMA connector style, male pin plug type, 50 Ohms impedance, free hanging (in-line) mounting, RG-402 cable compatibility, threaded fastening, 18 GHz maximum frequency, single port configuration, and solder shield termination. Secondary parameters such as body material and center contact composition may vary without affecting substitution validity.

Q: Can the Amphenol RF 901-9201-1ASF be used in place of the 1050542-1?

A: Yes. The Amphenol RF 901-9201-1ASF meets all primary matching parameters. The extended operating temperature range (-65°C ~ 165°C) provides additional thermal margin. ROHS3 compliance exceeds the RoHS compliance requirement of the original part. Mating cycle rating of 500 matches the original specification.

Q: Can the Cinch Connectivity Solutions Johnson 142-0694-021 be used in place of the 1050542-1?

A: Yes. The Cinch Connectivity Solutions Johnson 142-0694-021 meets all primary matching parameters. The extended operating temperature range (-65°C ~ 165°C) provides additional thermal margin. The 335 V voltage rating matches the original specification. The mating cycle rating of 100 is lower than the original 500 cycles; applications requiring higher cycle counts should evaluate this difference. The brass body material differs from the original stainless steel construction.

Q: What is the significance of the packaging difference between these parts?

A: The TE Connectivity AMP Connectors 1050542-1 packaging is not specified. The Cinch Connectivity Solutions Johnson 142-0694-021 is supplied in bulk packaging and includes 2 pieces per unit (1 connector and 1 coupling nut). This packaging configuration may affect inventory management and assembly procedures. Verify packaging requirements for your application before selection.

Q: Are there compliance differences between the substitute parts?

A: The TE Connectivity AMP Connectors 1050542-1 carries RoHS compliance certification. The Amphenol RF 901-9201-1ASF carries ROHS3 compliance certification and is REACH affected. The Cinch Connectivity Solutions Johnson 142-0694-021 carries RoHS compliance certification. All three parts carry EAR99 ECCN classification and 8536.69.4010 HTSUS code. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the difference in mating cycle ratings?

A: The TE Connectivity AMP Connectors 1050542-1 and Amphenol RF 901-9201-1ASF both specify 500 mating cycles. The Cinch Connectivity Solutions Johnson 142-0694-021 specifies 100 mating cycles. Mating cycles indicate the number of times a connector can be mated and unmated while maintaining electrical and mechanical performance. Applications requiring frequent connection and disconnection should prioritize parts with higher cycle ratings.

Q: Can body material differences affect connector performance?

A: The TE Connectivity AMP Connectors 1050542-1 uses stainless steel body material. The Amphenol RF 901-9201-1ASF uses stainless steel body material. The Cinch Connectivity Solutions Johnson 142-0694-021 uses brass body material. All three parts feature gold finish. Body material affects mechanical durability, corrosion resistance, and thermal properties. Stainless steel provides superior corrosion resistance in harsh environments. Brass offers good electrical conductivity and cost efficiency. For applications in corrosive environments or requiring maximum durability, stainless steel construction is preferred.
