Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for coaxial RF connectors is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish substitution validity:

Primary Substitution Criteria:

• Connector style must be identical (SMA)
• Connector type must be identical (Jack, Female Socket)
• Impedance must be identical (50 Ohms)
• Mounting type must be identical (Panel Mount)
• Mounting feature must be identical (Bulkhead - Front Side Nut)
• Number of ports must be identical (1)
• Voltage rating must be equal or greater (250 V minimum)
• Mating cycles must be equal or greater (500 minimum)

Secondary Compatibility Factors:

• Contact termination may vary (Solder, Crimp, or Crimp or Solder)
• Frequency maximum may exceed the primary part specification
• Operating temperature range may exceed the primary part specification
• Center contact material and plating must maintain electrical performance
• Dielectric material must be PTFE for RF performance consistency

The substitute part 142-0303-416 meets all primary substitution criteria and exceeds several secondary performance parameters.

Engineering Selection Recommendations

Primary Part: 1056452-1 (TE Connectivity AMP Connectors)

The TE Connectivity 1056452-1 maintains active product status with full RoHS compliance and REACH compliance documentation. This part is suitable for applications requiring solder termination with standard SMA jack specifications. The part carries 1048 units in current inventory.

Substitute Part: 142-0303-416 (Cinch Connectivity Solutions)

The Cinch Connectivity Solutions 142-0303-416 is qualified as a direct substitute based on identical core electrical and mechanical parameters. This part offers extended frequency capability (12.4 GHz versus 6 GHz) and expanded operating temperature range (-65°C to 165°C versus -40°C to 95°C). The part supports both crimp and solder termination options, providing additional assembly flexibility. ROHS3 compliance status exceeds RoHS compliance requirements. The part carries 1203 units in current inventory.

Selection Basis:

Both parts satisfy identical substitution criteria for SMA jack, female socket, 50 ohm, panel mount applications. Selection between these parts depends on termination method requirements and operating environment specifications. The Cinch part provides performance margin for higher frequency applications and extended temperature environments. The TE Connectivity part is appropriate for standard frequency and temperature operating ranges with solder-only termination requirements.

Frequently Asked Questions (FAQ)

Q: Can the 142-0303-416 be used as a direct replacement for the 1056452-1?

A: Yes. Both connectors share identical SMA jack female socket configuration, 50 ohm impedance, panel mount bulkhead mounting, 250 V voltage rating, and 500 mating cycle specification. The 142-0303-416 supports both crimp and solder termination, making it compatible with solder-only applications.

Q: What is the difference in shield termination between these parts?

A: The 1056452-1 uses clamp shield termination, while the 142-0303-416 uses crimp shield termination. Both methods provide equivalent RF shielding performance for 50 ohm coaxial applications.

Q: Does the higher frequency rating of the 142-0303-416 affect compatibility?

A: No. The 142-0303-416 frequency rating of 12.4 GHz exceeds the 1056452-1 specification of 6 GHz. This provides performance margin without affecting compatibility in applications operating at or below 6 GHz.
