• Connector Type: Receptacle
• Number of Positions: 10
• Pitch - Mating: 0.079" (2.00mm)
• Mounting Type: Surface Mount
• Contact Finish - Mating: Gold
• Current Rating: 3.2A per Contact
• Voltage Rating: 350VAC
• Operating Temperature: -55°C ~ 125°C
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Material: Beryllium Copper
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Packaging: Tape & Reel (TR)

The identified substitutes differ only in fastening mechanism designation (K or P variant) while maintaining full electrical and mechanical compatibility with the main part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SMM-110-02-L-S-TR, SMM-110-02-L-S-K-TR, and SMM-110-02-L-S-P-TR—maintain active product status with identical electrical performance, mechanical compatibility, and regulatory compliance. Each part is ROHS3 compliant and carries MSL 1 rating, ensuring equivalent reliability in surface mount applications.

Selection between these parts should be based on inventory availability and specific fastening mechanism requirements as designated by the part number suffix. The SMM-110-02-L-S-K-TR and SMM-110-02-L-S-P-TR variants include pick-and-place features, which may provide manufacturing process advantages in automated assembly environments.

Frequently Asked Questions (FAQ)

Q: Are SMM-110-02-L-S-TR, SMM-110-02-L-S-K-TR, and SMM-110-02-L-S-P-TR electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including 3.2A per contact current rating, 350VAC voltage rating, and gold-plated mating contacts with 10.0µin (0.25µm) thickness. They are fully interchangeable in electrical function.

Q: What is the difference between the K and P variants?

A: The K and P designations indicate different fastening mechanism variants within the Tiger Eye™ SMM series. Both maintain identical electrical and mechanical parameters. The specific functional difference is determined by the fastening type designation in the part number.

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

A: Yes. All three parts feature identical 0.079" (2.00mm) pitch, 10-position configuration, surface mount termination, and mechanical dimensions. PCB footprints and mating interfaces are compatible across all three part numbers.

Q: Are there any compliance or certification differences?

A: No. All three parts maintain identical RoHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Regulatory and environmental compliance is equivalent across all variants.

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

A: The operating temperature range for all three parts is -55°C to 125°C, supporting applications across industrial, commercial, and extended temperature environments.

Q: Are these parts available in standard packaging?

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly processes.
