Parameter Comparison

Engineering Selection Recommendations

The 7-2287906-0 manufactured by TE Connectivity AMP Connectors is a parametric equivalent to the 2FA1-WZSP-PCBA3 based on matching electrical and mechanical specifications. Both connectors maintain 50-ohm impedance, 6 GHz frequency capability, SMB Fakra plug configuration with right-angle through-hole solder termination, and locking ramp fastening.

Compliance Alignment: Both parts are ROHS3 compliant and carry Active product status, meeting current regulatory requirements for production applications.

Operational Considerations: The substitute part operates within a narrower temperature range (-40°C to 85°C versus -40°C to 100°C). Applications requiring operation above 85°C require the primary part 2FA1-WZSP-PCBA3.

The substitute part carries MSL 1 (Unlimited) versus MSL 4 (72 Hours) for the primary part, indicating superior moisture resistance and reduced handling constraints during storage and assembly.

Material Differences: The substitute part uses tin body finish and PCT/polyester dielectric material, compared to gold finish and PTFE dielectric in the primary part. These material differences do not affect electrical performance at specified operating frequencies and impedance.

Frequently Asked Questions (FAQ)

Q: Can 7-2287906-0 be used as a direct replacement for 2FA1-WZSP-PCBA3 in all applications?

A: The 7-2287906-0 is electrically and mechanically equivalent for RF coaxial applications up to 6 GHz at 50 ohms. Applications operating above 85°C require the primary part due to the narrower operating temperature range of the substitute.

Q: What is the difference in dielectric material between these connectors?

A: The primary part uses PTFE (Polytetrafluoroethylene) dielectric, while the substitute uses PCT (Polycyclohexylenedimethylene Terephthalate) with polyester. Both materials support 6 GHz operation and 50-ohm impedance. Material selection does not affect RF performance within specified parameters.

Q: Does the difference in body finish (gold versus tin) affect performance?

A: Body finish does not affect electrical performance. Gold finish provides enhanced corrosion resistance; tin finish is standard for general RF applications. Selection depends on environmental exposure requirements.

Q: Why does the substitute part have lower Moisture Sensitivity Level (MSL)?

A: MSL 1 (Unlimited) for the substitute indicates superior moisture resistance compared to MSL 4 (72 Hours) for the primary part. This provides advantages in humid storage environments and reduces handling constraints during assembly.

Q: Are both parts suitable for production use?

A: Both parts carry Active product status and ROHS3 compliance, confirming suitability for current production applications.

Q: What is the significance of REACH status difference?

A: The primary part is REACH Affected; the substitute is REACH Unaffected. This indicates different regulatory substance declarations. Compliance requirements depend on end-market and application jurisdiction.

Q: Can these connectors be used interchangeably in the same PCB design?

A: Yes, both connectors share identical mounting footprints (through-hole, right-angle configuration) and electrical specifications (50 ohms, 6 GHz, solder termination). PCB layout compatibility is maintained.
