Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMM-104-02-S-S-TR are qualified based on identical electrical and mechanical parameters that ensure direct functional compatibility. The substitution criteria are strictly limited to the following parameters:

• Connector type (Receptacle)
• Number of positions (4)
• Mating pitch (0.079" / 2.00mm)
• Mounting type (Surface Mount)
• Contact type (Female Socket)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Current rating (3.2A per Contact)
• Voltage rating (350VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specification (Gold mating surface)
• Insulation material (Liquid Crystal Polymer)
• Flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)
• Moisture sensitivity level (MSL 1)

The identified substitutes differ only in packaging configuration or pick-and-place feature designation, which do not affect electrical or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—SMM-104-02-S-S-TR, SMM-104-02-S-S-K-TR, and SMM-104-02-S-S-P-TR—are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Compliance & Certification: All parts maintain ROHS3 compliance and UL94 V-0 flammability rating, meeting standard industrial and consumer electronics requirements.

Manufacturing Process: SMM-104-02-S-S-K-TR and SMM-104-02-S-S-P-TR include pick-and-place feature designation, indicating suitability for automated assembly processes. SMM-104-02-S-S-TR is the standard configuration without this designation.

Inventory Availability: SMM-104-02-S-S-P-TR offers the highest inventory level (2647 pcs), followed by SMM-104-02-S-S-K-TR (2000 pcs) and SMM-104-02-S-S-TR (1004 pcs).

Application Compatibility: All three parts are electrically and mechanically interchangeable for board-to-board or cable interconnect applications within the specified current (3.2A per contact) and voltage (350VAC) ratings.

Frequently Asked Questions (FAQ)

Q: Are SMM-104-02-S-S-K-TR and SMM-104-02-S-S-P-TR direct replacements for SMM-104-02-S-S-TR?

A: Yes. All three part numbers share identical electrical and mechanical parameters, including connector type, position count, mating pitch, contact rating, voltage rating, operating temperature range, and material specifications. The differences are limited to pick-and-place feature designation and inventory levels.

Q: What does the pick-and-place feature designation mean?

A: The pick-and-place feature indicates the connector is optimized for automated assembly equipment used in high-volume manufacturing. This does not affect electrical or mechanical compatibility in the application.

Q: Can these connectors be used interchangeably in the same PCB design?

A: Yes. The connectors are mechanically and electrically identical, with the same footprint, mating interface, and electrical performance. PCB designs do not require modification when substituting between these part numbers.

Q: What is the significance of the MSL 1 (Unlimited) moisture sensitivity level?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions and does not require special moisture control during handling or storage, simplifying logistics and inventory management.

Q: Are all three parts RoHS compliant?

A: Yes. All three part numbers are ROHS3 compliant, meeting European Union Restriction of Hazardous Substances regulations.
