Substitute Part Grouping Explanation

Substitution of rectangular connectors in the SMM series is determined by strict equivalence across the following critical parameters:

  • Connector Type & Contact Configuration: Both parts must be receptacles with female socket contacts
  • Position Count & Pitch: 20 positions at 0.079" (2.00mm) mating pitch with 2-row configuration
  • Electrical Ratings: 3.2A per contact and 350VAC voltage rating
  • Mounting & Termination: Surface mount with solder termination
  • Contact Material & Finish: Beryllium copper with gold mating finish (30.0µin thickness) and tin post finish
  • Environmental Specifications: Operating temperature range -55°C ~ 125°C and UL94 V-0 flammability rating
  • Insulation Material: Liquid Crystal Polymer (LCP) with black color and 0.140" (4.66mm) height

The substitute part SMM-110-02-S-D-01-K meets all these criteria. The primary difference is packaging format (Tube vs. standard packaging), which does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Both SMM-110-02-S-D-02-K and SMM-110-02-S-D-01-K are Active products from Samtec Inc. and are electrically and mechanically interchangeable for all board-to-board and cable connector applications requiring 20-position, 2.00mm pitch receptacle connectors.

Selection between these parts should be based on:

  • Packaging Requirements: Choose SMM-110-02-S-D-01-K if Tube packaging is specified for your procurement or assembly process
  • Compliance Certification: SMM-110-02-S-D-01-K explicitly lists ROHS3 compliance; select this variant if RoHS3 certification is a design requirement
  • Inventory Availability: SMM-110-02-S-D-02-K has 960 units in stock; SMM-110-02-S-D-01-K has 786 units in stock

Both parts satisfy UL94 V-0 flammability requirements, MSL 1 moisture sensitivity, and export classification EAR99.

Frequently Asked Questions (FAQ)

Q: Can SMM-110-02-S-D-01-K be used as a direct replacement for SMM-110-02-S-D-02-K?

A: Yes. Both parts are electrically and mechanically identical receptacle connectors with 20 positions, 0.079" (2.00mm) pitch, 2-row configuration, and identical electrical ratings (3.2A per contact, 350VAC). The only difference is packaging format (Tube vs. standard).

Q: What is the significance of the packaging difference between these two parts?

A: Packaging affects handling, storage, and assembly processes. Tube packaging (SMM-110-02-S-D-01-K) is suitable for automated pick-and-place equipment and specific procurement workflows. Standard packaging (SMM-110-02-S-D-02-K) accommodates alternative assembly methods. Electrical and mechanical performance are unaffected.

Q: Are there any compliance differences between these parts?

A: SMM-110-02-S-D-01-K explicitly specifies ROHS3 compliance. Both parts meet UL94 V-0 flammability and EAR99 export classification. If RoHS3 certification is required for your application, select SMM-110-02-S-D-01-K.

Q: What are the critical parameters that define substitution eligibility for this connector?

A: Substitution is valid only when the following parameters match: connector type (receptacle), contact type (female socket), position count (20), mating pitch (0.079"), row configuration (2 rows), mounting type (surface mount), termination method (solder), contact material (beryllium copper), mating finish (gold), electrical ratings (3.2A, 350VAC), and operating temperature range (-55°C ~ 125°C).

Q: Can these connectors be used in applications outside the specified operating temperature range?

A: No. Both parts are rated for -55°C ~ 125°C operation. Use outside this range is not supported by the manufacturer specifications.
