Engineering Selection Recommendations

Both MHSD-04C-AM-PRA-TR and MHSD-04C-BM-PRA-TR are Active products from Adam Tech with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

Packaging Requirements: Choose MHSD-04C-AM-PRA-TR for automated assembly processes requiring Tape & Reel format. Select MHSD-04C-BM-PRA-TR for manual assembly or lower-volume applications utilizing Cut Tape format.

Inventory Availability: MHSD-04C-BM-PRA-TR currently has higher inventory (2168 pieces) compared to MHSD-04C-AM-PRA-TR (725 pieces).

Contact Plating Specification: Both Gold and Silver plating are suitable for 50 Ohm RF applications at frequencies up to 9 GHz. The choice between Gold (MHSD-04C-AM-PRA-TR) and Silver (MHSD-04C-BM-PRA-TR) plating should align with existing design specifications and corrosion resistance requirements for the intended application environment.

Frequently Asked Questions (FAQ)

Q: Can MHSD-04C-BM-PRA-TR be used as a direct replacement for MHSD-04C-AM-PRA-TR in PCB assembly?

A: Yes. Both parts are electrically and mechanically identical. The primary difference is packaging format (Tape & Reel versus Cut Tape). If your assembly process accommodates Cut Tape format, MHSD-04C-BM-PRA-TR is a valid substitute.

Q: What is the difference between Gold and Silver center contact plating?

A: Both plating materials are compatible with the 50 Ohm impedance and 9 GHz frequency specification. Gold plating (MHSD-04C-AM-PRA-TR) and Silver plating (MHSD-04C-BM-PRA-TR) differ in corrosion resistance characteristics. Selection should be based on your application's environmental exposure and design requirements.

Q: Are both parts suitable for high-frequency RF applications?

A: Yes. Both MHSD-04C-AM-PRA-TR and MHSD-04C-BM-PRA-TR support frequencies up to 9 GHz with 50 Ohms impedance, making them suitable for identical RF applications.

Q: What does the packaging designation (TR vs. CT) mean?

A: TR (Tape & Reel) is used for high-volume automated assembly. CT (Cut Tape) is used for lower-volume or manual assembly processes. The connector itself is identical; only the delivery format differs.

Q: Are both parts RoHS compliant?

A: Yes. Both MHSD-04C-AM-PRA-TR and MHSD-04C-BM-PRA-TR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -40°C to 105°C, suitable for industrial and automotive RF applications.
