Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1050536-1 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line)
• Shield Termination: Solder
• Fastening Type: Threaded
• Frequency - Max: 18 GHz or higher
• Number of Ports: 1

Secondary Compatibility Factors:

• Cable Group compatibility (RG-402 semi-rigid preferred)
• Operating temperature range (minimum -65°C to 105°C)
• Voltage rating (minimum 335 V)
• Mating cycles (minimum 500)
• Body finish (Gold)

Substitute parts are classified into two categories: Direct Substitutes (matching all primary criteria with identical cable group specifications) and Similar Substitutes (matching all primary criteria with compatible but different cable group specifications or enhanced performance parameters).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

All substitute parts maintain the critical 50 ohm impedance, SMA connector style, male pin configuration, solder shield termination, and threaded fastening type required for functional equivalence. Selection should prioritize active product status and ROHS3 compliance for new designs. For legacy system maintenance, parts with matching cable group specifications (RG-402 semi-rigid) provide the highest mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different cable group (RG-405 instead of RG-402) in my existing assembly?

A: Cable group compatibility depends on your mechanical assembly design. RG-405 (.086" semi-rigid) has a smaller outer diameter than RG-402 (.141" semi-rigid). The connector interface itself remains electrically compatible at 50 ohms impedance, but physical fitment in cable routing and strain relief must be evaluated for your specific application. Parts 142-0693-001 and 901-9201-2ASF use RG-405 cable groups.

Q: What is the difference between the original 1050536-1 and the substitute parts regarding operating temperature?

A: The original 1050536-1 operates from -65°C to 105°C. Most substitute parts extend this range to -65°C to 165°C, providing enhanced thermal performance. This extended range does not affect compatibility in applications using the original temperature specification but provides additional operational margin for demanding environments.

Q: Why do some substitute parts have different body materials (brass versus stainless steel)?

A: Both brass and stainless steel bodies with gold finish meet the 50 ohm impedance and electrical performance requirements. Stainless steel (used in 901-9808, 901-9808-2, 901-9201-1ASF, 901-9201-2ASF) offers superior corrosion resistance. Brass bodies (used in 142-0693-001, 142-0694-001, 142-0694-021) provide alternative material sourcing. Both are functionally equivalent for the specified electrical parameters.

Q: Is the reduced mating cycle rating on part 142-0694-021 (100 cycles versus 500 cycles) a concern?

A: The mating cycle rating indicates the number of connect/disconnect operations the connector can withstand. If your application requires frequent mating cycles, parts with 500-cycle ratings are preferred. For fixed installations with minimal mating operations, the 100-cycle rating of 142-0694-021 is acceptable.

Q: What does ROHS3 compliance mean compared to RoHS compliance on the original part?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. The original part carries RoHS Compliant status. Both are acceptable for new designs; ROHS3 compliant parts (901-9808, 901-9808-2, 142-0693-001, 142-0694-001, 901-9201-1ASF, 901-9201-2ASF) align with current regulatory requirements.

Q: Can I substitute a part with a higher frequency rating (26.5 GHz) for my 18 GHz application?

A: Yes. Part 142-0693-001 with 26.5 GHz maximum frequency is fully compatible with 18 GHz applications. Higher frequency ratings indicate broader operational capability and do not create incompatibility with lower-frequency systems. The 50 ohm impedance and connector geometry remain consistent.

Q: What is the significance of the "Weatherproof" ingress protection on part 901-9201-2ASF?

A: Weatherproof ingress protection indicates enhanced sealing against moisture and environmental contamination. This feature is beneficial for outdoor or harsh environment applications but is not required for standard indoor RF applications. The original 1050536-1 does not specify ingress protection, so weatherproof variants provide optional environmental enhancement.

Q: Are all substitute parts available in the same packaging as the original?

A: The original 1050536-1 packaging is not specified in the documentation. Most substitute parts are available in bulk packaging. Specific packaging requirements should be confirmed with component suppliers based on your procurement needs.

Q: Which substitute part provides the best overall compatibility with the original 1050536-1?

A: Amphenol RF 901-9808 and 901-9808-2 provide the highest compatibility, matching the RG-402 semi-rigid cable group, maintaining stainless steel construction, and offering active product status with ROHS3 compliance. Both parts are in substantial inventory (3052 and 687 units respectively) and provide extended operating temperature capability.
