Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMP-MSLD-PCS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: SMP
• Impedance: 50 Ohms
• Mounting Type: Surface Mount
• Contact Termination: Solder
• Shield Termination: Solder
• Base Product Number: SMP-MSLD
• Fastening Type: Snap-On
• Number of Ports: 1
• Center Contact Material: Brass
• Body Material: Brass
• Dielectric Material: Liquid Crystal Polymer (LCP)
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variations:

• Connector Type: Receptacle/Jack configurations within the SMP-MSLD family
• Packaging: Bulk or Tape & Reel
• Frequency - Max: Equal to or greater than 18 GHz
• Operating Temperature: May differ based on application requirements
• Product Status: Active status preferred for new procurement

The SMP-MSLD-PCS20T qualifies as a substitute based on matching all mandatory parameters while offering enhanced frequency capability (20 GHz) and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs Using SMP-MSLD-PCS:

The SMP-MSLD-PCS20T serves as the active equivalent within the Amphenol RF SMP-MSLD product family. Both connectors share identical mechanical and electrical core specifications: 50-ohm impedance, SMP style, surface mount solder termination, and snap-on fastening. Both maintain ROHS3 compliance and MSL Level 1 rating.

Key Considerations:

1. Product Status: The SMP-MSLD-PCS is designated Not For New Designs. The SMP-MSLD-PCS20T carries Active status, making it the recommended selection for ongoing procurement and new applications.

2. Frequency Performance: The SMP-MSLD-PCS20T extends maximum frequency capability to 20 GHz compared to 18 GHz for the original part. This enhanced specification is backward compatible with 18 GHz system requirements.

3. Operating Temperature Range: The SMP-MSLD-PCS operates across -65°C to 165°C, while the SMP-MSLD-PCS20T operates across -40°C to 85°C. Applications requiring the full -65°C to 165°C range must retain the original part or identify alternative solutions outside this family.

4. Packaging Format: SMP-MSLD-PCS is supplied in Bulk packaging; SMP-MSLD-PCS20T is supplied in Tape & Reel format. Packaging selection depends on assembly process requirements and inventory management practices.

5. Regulatory Compliance: Both parts maintain identical ROHS3 and REACH compliance status, supporting equivalent regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SMP-MSLD-PCS20T directly replace SMP-MSLD-PCS in existing assemblies?

A: Yes, for applications operating within -40°C to 85°C temperature range. Both connectors share identical SMP style, 50-ohm impedance, surface mount solder termination, and snap-on fastening. The SMP-MSLD-PCS20T provides equivalent or superior electrical performance. Applications requiring operation below -40°C or above 85°C must retain the original SMP-MSLD-PCS.

Q: What is the difference between Receptacle and Jack connector types in the SMP-MSLD family?

A: Within the SMP-MSLD family, Receptacle and Jack designations refer to different mating configurations. Both are male pin connectors with identical electrical and mechanical specifications. Selection depends on the mating connector type in the system design. Consult mating connector documentation to determine correct pairing.

Q: Are there packaging considerations when switching from SMP-MSLD-PCS to SMP-MSLD-PCS20T?

A: Yes. SMP-MSLD-PCS is supplied in Bulk packaging, while SMP-MSLD-PCS20T is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated surface mount assembly processes. Manual assembly or reel-to-bulk conversion may be required depending on assembly equipment and workflow.

Q: Does the 20 GHz frequency rating of SMP-MSLD-PCS20T affect compatibility with 18 GHz systems?

A: No. The SMP-MSLD-PCS20T is fully backward compatible with 18 GHz system specifications. Higher frequency capability does not degrade performance at lower frequencies. Both connectors maintain identical impedance, insertion loss characteristics, and mechanical interface specifications.

Q: What compliance certifications apply to both parts?

A: Both SMP-MSLD-PCS and SMP-MSLD-PCS20T are ROHS3 compliant and REACH affected. Both carry MSL Level 1 (Unlimited) moisture sensitivity rating. Regulatory documentation should be reviewed for specific application requirements.

Q: Why is SMP-MSLD-PCS marked as Not For New Designs?

A: Product status designations reflect manufacturer lifecycle management. Not For New Designs status indicates the part remains available for existing applications but is not recommended for new development. The SMP-MSLD-PCS20T represents the active equivalent for new designs within the same product family.
