Key Parameters

Substitute Part Grouping Explanation

The MSS-R-PC-3(40) qualifies as a parametric equivalent to the MSS-R-PC(40) based on the following criteria:

Matching Parameters:

• Identical impedance specification (50 Ohms)
• Same connector type (Receptacle, Female Socket)
• Identical mounting configuration (Through Hole, Solder termination)
• Matching frequency rating (1 GHz maximum)
• Identical operating temperature range (-55°C ~ 85°C)
• Same mating cycle rating (3000 cycles)
• Identical material composition (Beryllium Copper center contact, Brass body, PTFE dielectric)
• Same series designation (MSS)

Both parts are manufactured by Hirose Electric Co Ltd and share the same base product number (MSS-R), confirming their functional equivalence for RF coaxial connector applications.

Engineering Selection Recommendations

Primary Selection: MSS-R-PC(40)

The MSS-R-PC(40) is the recommended choice for new designs and ongoing production. This part maintains Active product status with established supply availability (746 units in stock) and carries ROHS3 compliance certification, ensuring alignment with current regulatory requirements.

Alternative Selection: MSS-R-PC-3(40)

The MSS-R-PC-3(40) is functionally equivalent and may be selected when MSS-R-PC(40) availability is constrained. This part carries RoHS compliance and maintains higher current inventory levels (1157 units). However, its Last Time Buy status indicates limited future availability. Selection of this substitute should account for long-term supply planning, as production will be discontinued.

Both parts satisfy identical electrical and mechanical requirements for 50 Ohm RF coaxial connector applications and are interchangeable at the circuit level.

Frequently Asked Questions (FAQ)

Q: Are MSS-R-PC(40) and MSS-R-PC-3(40) electrically interchangeable?

A: Yes. Both parts meet identical electrical specifications including 50 Ohm impedance, 1 GHz frequency rating, and -55°C to 85°C operating temperature range. They share identical contact materials, dielectric composition, and mating cycle ratings.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. MSS-R-PC(40) is in Active production, while MSS-R-PC-3(40) is designated Last Time Buy. Both are manufactured by Hirose Electric Co Ltd and are parametrically equivalent.

Q: Can I use MSS-R-PC-3(40) in place of MSS-R-PC(40) in existing designs?

A: Yes. The parts are functionally identical and can be used interchangeably in PCB designs. However, MSS-R-PC-3(40) has limited future availability due to its Last Time Buy status.

Q: What does Last Time Buy mean for MSS-R-PC-3(40)?

A: Last Time Buy indicates that Hirose Electric Co Ltd will discontinue production of this part number. Existing inventory will be available for a limited period, but no new production runs are planned.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant. MSS-R-PC(40) carries ROHS3 certification, while MSS-R-PC-3(40) carries standard RoHS certification. Both meet REACH requirements and carry EAR99 export classification.

Q: What is the packaging format for these connectors?

A: Both parts are supplied in Bulk packaging format.
