SMM-104-01-SM-D Equivalent & Substitute Parts

Part Overview

The SMM-104-01-SM-D is an 8-position receptacle connector from Samtec Inc.'s Tiger Eye™ SMM series, designed for board-to-board or cable applications. This through-hole mounted connector features a 0.079" (2.00mm) pitch with gold-plated mating contacts and is rated for 3.2A per contact at 350VAC. The part is Active status and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable interconnection in temperature ranges from -55°C to 125°C.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across different mounting technologies while preserving core connector functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMM-104-01-SM-D is determined by maintaining equivalence across the following critical parameters:

• Connector type (Receptacle) and contact type (Female Socket)
• Position count (8 positions) and row configuration (2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Electrical ratings (3.2A per contact, 350VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specification (Gold mating surface)
• Insulation material (Liquid Crystal Polymer)
• Compliance certifications (UL94 V-0, ROHS3)

The primary variable allowing substitution is the mounting technology. The SMM-104-01-SM-D uses through-hole termination, while equivalent parts may employ surface-mount termination, provided all other electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the SMM-104-01-SM-D and SMM-104-02-S-D maintain Active product status and full ROHS3 compliance. Selection between these parts is determined by PCB assembly requirements:

The SMM-104-01-SM-D through-hole configuration is appropriate for applications requiring mechanical robustness, manual assembly compatibility, or designs utilizing through-hole technology throughout the PCB layout.

The SMM-104-02-S-D surface-mount configuration is appropriate for high-density PCB designs, automated assembly processes, or applications where surface-mount technology is the standard assembly method.

Both parts deliver identical electrical performance, mechanical interface compatibility with mating connectors, and environmental operating specifications. The choice between them depends solely on the PCB assembly technology and design methodology employed in the target application.

Frequently Asked Questions (FAQ)

Q: Can SMM-104-02-S-D replace SMM-104-01-SM-D in an existing design?

A: Substitution is possible only if the PCB layout and assembly process can accommodate surface-mount termination. The electrical and mechanical interface characteristics are identical, but the mounting footprint and assembly method differ fundamentally.

Q: Are the mating connectors compatible between through-hole and surface-mount versions?

A: Yes. Both receptacle versions accept the same mating connector due to identical contact geometry, pitch, and row spacing specifications.

Q: What is the primary difference between these two parts?

A: The mounting technology. SMM-104-01-SM-D uses through-hole solder termination for PCB mounting, while SMM-104-02-S-D uses surface-mount solder termination. All other specifications, including electrical ratings, contact materials, and environmental performance, are equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, and carry identical ECCN and HTSUS classifications.

Q: What inventory considerations apply to these parts?

A: SMM-104-01-SM-D has 1056 pieces in stock, while SMM-104-02-S-D has 1674 pieces in stock. Both are available as new original components.
