Frequently Asked Questions (FAQ)

Q: Can 142-1701-616 and 142-1701-626 be used interchangeably with 142-1701-556?

A: Yes. All three parts are parametric equivalents with identical electrical and mechanical specifications, including impedance, frequency range, operating temperature, voltage rating, and mating cycle ratings. They are directly substitutable in applications requiring SMA jack connectors with 50-ohm compression termination and panel-mount flange configuration.

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

A: ROHS3 Compliant represents the current RoHS 2.0/3.0 directive compliance standard, which includes additional restricted substances compared to the original RoHS standard. Both certifications indicate compliance with hazardous substance restrictions; ROHS3 reflects the more recent regulatory framework.

Q: Are there any differences in packaging or handling between these parts?

A: All three parts are supplied in bulk packaging. Moisture Sensitivity Level (MSL) is rated as 1 (Unlimited) for all parts, indicating no special moisture control requirements during storage or handling.

Q: What does the REACH Affected status on 142-1701-616 and 142-1701-626 mean?

A: REACH Affected status indicates that these parts contain substances subject to the European REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulation. This designation is relevant for applications destined for European markets or subject to European regulatory requirements.

Q: Which part should be selected based on inventory availability?

A: Part 142-1701-616 has the highest inventory at 1213 units, followed by 142-1701-626 at 939 units, and 142-1701-556 at 731 units. Selection should prioritize availability based on procurement lead time requirements and supply chain strategy.
