SMM-117-01-S-D Equivalent & Substitute Parts

Part Overview

The SMM-117-01-S-D is a 34-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 gold-plated mating contacts and operates across a wide temperature range of -55°C to 125°C. The part is currently active in production with 790 units in stock. Alternative models may be required when application constraints necessitate different mounting technologies, position counts, or packaging formats while maintaining electrical and mechanical compatibility within the Tiger Eye™ SMM series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the Tiger Eye™ SMM series is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Parameters:

• Pitch - Mating: 0.079" (2.00mm) — must remain constant
• Current Rating: 3.2A per Contact — must be maintained or exceeded
• Voltage Rating: 350VAC — must be maintained or exceeded
• Contact Finish - Mating: Gold at 30.0µin (0.76µm) thickness
• Contact Material: Beryllium Copper

Mechanical Compatibility Parameters:

• Series: Tiger Eye™ SMM — all substitutes must belong to this series
• Connector Type: Receptacle with Female Socket contacts
• Termination: Solder
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0

Environmental & Compliance Parameters:

• Operating Temperature: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters Allowing Substitution:

• Number of Positions: May differ based on application requirements
• Mounting Type: Through Hole or Surface Mount variants acceptable
• Packaging: Tube or Bulk formats interchangeable

The SMM-117-02-S-S qualifies as a substitute based on matching all electrical and environmental parameters while differing in mounting technology (Surface Mount vs. Through Hole) and position count (17 vs. 34).

Parameter Comparison

Engineering Selection Recommendations

Both the SMM-117-01-S-D and SMM-117-02-S-S maintain identical electrical performance specifications, including current rating, voltage rating, and contact finish characteristics. Both parts are active products with full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory alignment across applications.

The primary selection criterion is mounting technology and position count. The SMM-117-01-S-D is specified for through-hole PCB mounting with 34 contact positions arranged in 2 rows. The SMM-117-02-S-S provides a 17-position, single-row surface-mount alternative. Selection between these parts depends on PCB assembly process requirements and circuit layout constraints rather than electrical performance differences.

Both connectors operate across the full -55°C to 125°C temperature range and maintain UL94 V-0 flammability compliance, supporting equivalent environmental performance in target applications.

Frequently Asked Questions (FAQ)

Q: Can SMM-117-02-S-S replace SMM-117-01-S-D in all applications?

A: Electrical and environmental compatibility is complete. However, the SMM-117-02-S-S has half the contact positions (17 vs. 34) and uses surface-mount termination instead of through-hole. Substitution is valid only when circuit design accommodates the reduced position count and PCB assembly process supports surface-mount technology.

Q: Are the contact specifications identical between these parts?

A: Yes. Both use beryllium copper contacts with 30.0µin (0.76µm) gold plating, 0.079" (2.00mm) pitch, 3.2A per-contact current rating, and 350VAC voltage rating.

Q: What is the difference in row configuration?

A: The SMM-117-01-S-D uses a 2-row configuration with 0.079" row spacing. The SMM-117-02-S-S uses a single-row configuration. This affects PCB footprint and connector dimensions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: Which part should be selected for new designs?

A: Selection depends on mounting technology availability in your manufacturing process and circuit layout requirements. Both parts are active products with equivalent electrical performance and compliance status.
