Parameter Comparison

Engineering Selection Recommendations

Both MHSD-04A-AM-PRA-TR and MHSD-04A-BM-PRA-TR are Active status products manufactured by Adam Tech and hold identical ROHS3 compliance and REACH Unaffected certifications. Selection between these parts is based on the following criteria:

MHSD-04A-AM-PRA-TR Selection Criteria:

• Tape & Reel packaging required for automated assembly processes
• Gold plating specification for enhanced corrosion resistance in demanding environments
• Current inventory: 701 pieces

MHSD-04A-BM-PRA-TR Selection Criteria:

• Cut Tape packaging suitable for manual assembly or lower-volume applications
• Silver plating specification acceptable for standard RF applications
• Higher inventory availability: 2991 pieces
• Insertion Loss specification provided: 0.75 dB

Both parts satisfy identical electrical, mechanical, and environmental specifications. Selection should be based on packaging requirements, plating preference, and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can MHSD-04A-BM-PRA-TR be used as a direct replacement for MHSD-04A-AM-PRA-TR?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary differences are packaging format (Cut Tape vs. Tape & Reel) and center contact plating material (Silver vs. Gold). Functional performance in 50 Ohm RF applications up to 9 GHz is equivalent.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is used for high-volume automated assembly processes with pick-and-place equipment. Cut Tape (CT) packaging is supplied as individual segments cut from the reel, suitable for manual assembly or lower-volume production runs. Both contain the same connector component.

Q: Does the center contact plating material affect RF performance?

A: Both Gold and Silver plating meet the 50 Ohm impedance and 9 GHz frequency specifications. Plating material selection is based on application requirements for corrosion resistance and environmental exposure rather than RF electrical performance.

Q: Are both parts RoHS compliant?

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

Q: What does the insertion loss specification of 0.75 dB indicate?

A: Insertion loss of 0.75 dB for MHSD-04A-BM-PRA-TR represents the signal attenuation through the connector at RF frequencies. This specification is provided for the substitute part; the main part does not specify insertion loss. Both parts operate within the same frequency range and impedance class.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the PCB layout and assembly process accommodate the packaging format difference. Tape & Reel requires automated pick-and-place capability, while Cut Tape is suitable for manual placement. Electrical and mechanical mating characteristics are identical.

Q: What is the mating cycle rating?

A: Both parts are rated for 25 mating cycles, indicating the connector can be mated and unmated 25 times before performance degradation. This is typical for Fakra connectors in automotive and RF applications.
