Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMM-107-02-SM-S is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle), contact type (Female Socket), and series (Tiger Eye™ SMM)
• Number of positions (7) and mating pitch (0.079" / 2.00mm)
• Electrical ratings: 3.2A per contact, 350VAC
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specification (Gold, 30.0µin thickness)
• Insulation material (LCP) and flammability rating (UL94 V-0)
• Termination method (Solder) and mounting type (Surface Mount)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute parts (SMM-107-02-SM-S-K, SMM-107-02-S-S-K, SMM-107-02-S-S-P) maintain all critical electrical and mechanical parameters. Variations in part numbering reflect differences in secondary features such as pick-and-place compatibility or contact post finish, which do not affect core connector functionality or interchangeability in applications requiring the specified electrical and thermal performance.

Parameter Comparison

Engineering Selection Recommendations

All four parts—SMM-107-02-SM-S, SMM-107-02-SM-S-K, SMM-107-02-S-S-K, and SMM-107-02-S-S-P—are Active status products from Samtec Inc. with identical electrical performance, thermal ratings, and compliance certifications. Selection between these parts should be based on:

1. Availability: SMM-107-02-S-S-P (1131 Pcs) and SMM-107-02-S-S-K (1090 Pcs) offer higher inventory levels compared to SMM-107-02-SM-S (848 Pcs) and SMM-107-02-SM-S-K (864 Pcs).

2. Manufacturing Process Requirements: Parts designated with "-K" suffix include pick-and-place compatibility features. Selection depends on whether automated assembly processes require this capability.

3. Compliance and Certification: All parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level, ensuring equivalence for regulated applications.

4. Contact Post Finish: All parts specify tin contact finish on the post, maintaining consistent solderability across the substitute group.

Frequently Asked Questions (FAQ)

Q: Are all four parts electrically interchangeable? A: Yes. All parts maintain identical electrical ratings (3.2A per contact, 350VAC), operating temperature range (-55°C ~ 125°C), and contact finish specifications (gold mating surface, 30.0µin thickness). They are electrically equivalent for all applications within these parameters.

Q: What is the difference between SMM-107-02-SM-S and SMM-107-02-S-S-K? A: The primary difference is the pick-and-place feature designation (indicated by the "-K" suffix in SMM-107-02-S-S-K and SMM-107-02-SM-S-K). This affects manufacturing process compatibility but does not alter electrical or mechanical performance. All other parameters remain identical.

Q: Can I substitute SMM-107-02-S-S-P for SMM-107-02-SM-S in my design? A: Yes. Both parts are 7-position receptacle connectors with 0.079" pitch, identical current and voltage ratings, and equivalent thermal performance. The "-P" designation indicates pick-and-place compatibility, which is a manufacturing feature that does not affect functional interchangeability.

Q: Are these parts suitable for high-temperature applications? A: Yes. All four parts are rated for operating temperatures from -55°C to 125°C and carry UL94 V-0 flammability certification, making them suitable for industrial and automotive applications within this temperature range.

Q: What does ROHS3 compliance mean for these connectors? A: ROHS3 compliance indicates that all parts meet Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials. All four substitute parts maintain this compliance, ensuring regulatory equivalence for applications in regulated markets.

Q: Is moisture sensitivity a concern for these connectors? A: No. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. These connectors can be stored and handled without special moisture control measures.
