Frequently Asked Questions (FAQ)

Q: Can 133-3701-216 be used as a direct replacement for 1264ES514?

A: Yes. Both parts are parametric equivalents sharing identical electrical and mechanical specifications: MCX jack female socket, 50-ohm impedance, through-hole solder termination, 6 GHz maximum frequency, and 500 mating cycles. The 133-3701-216 offers extended operating temperature range (-65°C ~ 165°C versus -55°C ~ 155°C) and includes RoHS3 compliance certification.

Q: What are the differences between 133-3701-216 and MXSF54NT?

A: Both parts meet identical electrical and mechanical parameters. Key differences include: 133-3701-216 carries RoHS3 and REACH Affected certifications with 335 V voltage rating; MXSF54NT carries RoHS and REACH Unaffected certifications. MXSF54NT has significantly higher inventory availability (7825 units versus 1799 units).

Q: Are there packaging differences between these MCX connectors?

A: 1264ES514 packaging is not specified in available documentation. Both 133-3701-216 and MXSF54NT are supplied in bulk packaging. Confirm packaging requirements with supplier specifications before final selection.

Q: Do all three parts support the same frequency range?

A: Yes. All three MCX jack connectors support maximum frequency of 6 GHz, making them suitable for identical RF applications within this frequency specification.

Q: Which substitute part should be selected for extended temperature applications?

A: Both 133-3701-216 and MXSF54NT support extended operating temperature range of -65°C ~ 165°C, compared to 1264ES514's -55°C ~ 155°C. Either substitute is suitable for applications requiring the extended temperature specification.

Q: Are compliance certifications identical across all three parts?

A: All three parts share ECCN EAR99 and HTSUS 8536.69.4010 classifications. 133-3701-216 includes RoHS3 and REACH Affected status. MXSF54NT includes RoHS and REACH Unaffected status. 1264ES514 compliance details are limited to ECCN and HTSUS classifications. Select based on specific regulatory requirements for your application.
