Engineering Selection Recommendations

All listed substitute parts maintain functional equivalence to the R125462000 based on matching SMA connector style, 50 Ohm impedance, 18 GHz frequency capability, panel mount flange configuration, and solder termination. Selection among substitutes should prioritize the following factors:

Compliance and Certification: Parts with ROHS3 Compliant status (R125464000, R125512000, 142-1701-031, 142-1701-041, 142-1701-336, 23_SMA-50-0-13/111_NE, 2950-6061) align with current regulatory requirements. The original R125462000 carries RoHS Compliant status, which remains acceptable for existing designs.

Manufacturer Continuity: Radiall USA, Inc. parts (R125462000, 9308-1113-001, R125464000, R125512000) provide supply chain consistency. Cinch Connectivity Solutions and Amphenol SV Microwave alternatives offer expanded inventory availability.

Operating Temperature Range: The R125462000 operates from -65°C to 165°C. The 23_SMA-50-0-13/111_NE operates to -65°C to 125°C, which is suitable for applications not requiring the extended upper temperature capability.

Voltage Rating: The R125462000 is rated for 500 V. Cinch Connectivity Solutions parts are rated for 335 V, which remains adequate for standard RF applications but should be verified for high-voltage circuit requirements.

Inventory Availability: 142-1701-336 (5129 Pcs), R125512000 (1409 Pcs), and 2950-6061 (2100 Pcs) offer the highest stock levels for immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can I substitute the R125462000 with any of the listed parts without circuit redesign?

A: Yes. All listed parts maintain identical SMA connector style, 50 Ohm impedance, 18 GHz frequency capability, panel mount flange mounting, and solder termination. Electrical and mechanical compatibility is preserved across all substitutes.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. Parts with either certification are acceptable; ROHS3 Compliant parts align with current manufacturing standards.

Q: Does the body material difference (Stainless Steel vs. Brass vs. Beryllium Copper) affect performance?

A: No. All body materials specified maintain the required electrical conductivity and shielding effectiveness for 50 Ohm RF applications. Material selection reflects manufacturing process variations and does not impact functional performance in standard RF circuits.

Q: Why do some parts have lower voltage ratings (335 V vs. 500 V)?

A: Voltage rating differences reflect design variations among manufacturers. For standard RF signal transmission applications, both ratings are adequate. Verify voltage requirements for your specific circuit design, particularly in high-voltage or high-power applications.

Q: Is the operating temperature range difference (-65°C ~ 165°C vs. -65°C ~ 125°C) significant?

A: The difference is relevant only for applications requiring operation above 125°C. For standard RF applications operating within -65°C to 125°C, both temperature ranges are functionally equivalent. Verify your application's thermal requirements before selection.

Q: What packaging options are available?

A: The R125462000 is supplied in standard packaging. Substitute parts are available in Bulk, Box, or Bulk packaging configurations. Packaging does not affect electrical or mechanical performance; selection depends on procurement and inventory management requirements.

Q: Are all parts suitable for immediate substitution in existing PCB designs?

A: Yes. All substitute parts maintain identical SMA connector geometry, flange mounting configuration, and solder termination compatibility. No PCB layout modifications are required for direct substitution.
