Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSS-R-PC-3(40) is determined by strict parametric matching across the following critical criteria:

Electrical Parameters:

• Impedance: 50 Ohms (mandatory match)
• Frequency rating: 1 GHz maximum (mandatory match)
• Connector type: Receptacle, Female Socket (mandatory match)

Mechanical Parameters:

• Series: MSS (mandatory match)
• Mounting type: Through Hole (mandatory match)
• Contact termination: Solder (mandatory match)
• Mating cycles: 3000 (mandatory match)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C ~ 85°C (mandatory match)
• RoHS compliance status (must meet or exceed original specification)

The MSS-R-PC(40) qualifies as a parametric equivalent because it maintains identical electrical, mechanical, and environmental specifications while differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MSS-R-PC(40) is the direct parametric equivalent for MSS-R-PC-3(40) applications. Selection between these parts should be based on the following factors:

For New Designs or Restocking: Use MSS-R-PC(40). This part maintains Active product status, ensuring long-term availability and supply chain stability. It meets ROHS3 compliance, which exceeds the RoHS Compliant specification of the original part, providing enhanced environmental and regulatory alignment.

For Legacy System Maintenance: Either part is electrically and mechanically interchangeable. The MSS-R-PC(40) is preferred due to its Active status and superior compliance certification. Inventory availability should be verified with the supplier, as MSS-R-PC-3(40) is in Last Time Buy status.

Compliance Considerations: Both parts are RoHS compliant. The MSS-R-PC(40) carries ROHS3 Compliant and REACH Affected designations, indicating compliance with current EU environmental regulations. No functional or performance differences exist between the two parts.

Frequently Asked Questions (FAQ)

Q: Can MSS-R-PC(40) be used as a direct replacement for MSS-R-PC-3(40)?

A: Yes. Both parts are identical in all critical electrical and mechanical parameters: 50-ohm impedance, 1 GHz frequency rating, through-hole solder termination, and -55°C to 85°C operating range. They are functionally interchangeable in all applications where MSS-R-PC-3(40) is specified.

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

A: The primary differences are product status and compliance certifications. MSS-R-PC-3(40) is Last Time Buy (discontinued), while MSS-R-PC(40) is Active. MSS-R-PC(40) carries ROHS3 Compliant and REACH Affected certifications, compared to RoHS Compliant for the original part. No electrical or mechanical differences exist.

Q: Why should I choose MSS-R-PC(40) over MSS-R-PC-3(40)?

A: MSS-R-PC(40) is the recommended choice for new procurement because it is in Active production status, ensuring reliable long-term supply. It also meets ROHS3 compliance, which is the current environmental standard. MSS-R-PC-3(40) is in Last Time Buy status, meaning production is ending and future availability is limited.

Q: Are there any performance differences between these connectors?

A: No. Both parts have identical performance specifications: 50-ohm impedance, 1 GHz maximum frequency, 3000 mating cycles, and -55°C to 85°C operating temperature range. They use the same materials (beryllium copper contacts, brass body, PTFE dielectric) and termination method (solder).

Q: Can I mix these parts in the same assembly?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably within the same assembly or system without any functional impact.

Q: What packaging is available for these parts?

A: Both parts are supplied in Bulk packaging. Verify specific packaging requirements and minimum order quantities with your supplier.
