Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMM-110-02-S-S-P-TR are qualified based on the following critical parameters that must remain constant:

• Connector Type & Series: Receptacle connectors from the Tiger Eye™ SMM series
• Position Count: 10-position configuration
• Pitch: 0.079" (2.00mm) mating pitch
• Mounting: Surface mount technology
• Contact Rating: 3.2A per contact at 350VAC
• Operating Temperature Range: -55°C ~ 125°C
• Material Compliance: UL94 V-0 flammability rating, ROHS3 compliant
• Contact Material & Finish: Beryllium copper with gold mating surface (30.0µin thickness) and tin post finish

The identified substitutes maintain these core electrical and mechanical specifications while varying in fastening mechanism or contact post configuration, as reflected in the part number suffix variations.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SMM-110-02-S-S-P-TR, SMM-110-02-S-S-K-TR, and SMM-110-02-SM-S-K-TR—are active production components from Samtec Inc. with identical electrical ratings, operating temperature ranges, and compliance certifications. Each part maintains ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification.

Selection between these parts is determined by application-specific requirements related to fastening mechanism and contact post configuration, as indicated by the part number suffixes. All three are suitable for 10-position, 0.079" pitch surface mount applications requiring 3.2A per contact at 350VAC.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SMM-110-02-S-S-P-TR?

A: Substitute parts must maintain identical specifications for connector type, position count (10), mating pitch (0.079"), mounting method (surface mount), contact ratings (3.2A per contact, 350VAC), operating temperature range (-55°C ~ 125°C), and material compliance (UL94 V-0, ROHS3). Variations in fastening mechanism or contact post configuration do not affect substitutability.

Q: Are all three substitute parts electrically equivalent?

A: Yes. SMM-110-02-S-S-K-TR and SMM-110-02-SM-S-K-TR maintain identical electrical specifications, current ratings, voltage ratings, and operating temperature ranges as the primary part SMM-110-02-S-S-P-TR.

Q: What is the difference between these part numbers?

A: The differences are encoded in the part number suffixes. The primary variation relates to fastening type and contact post configuration. All parts are functionally equivalent for 10-position, 0.079" pitch receptacle applications.

Q: Are these parts interchangeable in PCB design?

A: Yes, provided the application requirements align with the specified electrical and mechanical parameters. All three parts are surface mount receptacles with identical pitch, position count, and contact ratings.

Q: What is the inventory status for these parts?

A: SMM-110-02-S-S-P-TR has 1047 units in stock, SMM-110-02-S-S-K-TR has 3463 units, and SMM-110-02-SM-S-K-TR has 3113 units available as new original stock.

Q: Do these parts require different handling or storage procedures?

A: All three parts share identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling.
