SMM-109-01-S-D Equivalent & Substitute Parts

Part Overview

The SMM-109-01-S-D is an 18-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 maintains Active product status and is ROHS3 compliant. Substitute parts are identified when electrical and mechanical parameters remain identical across connector pitch, position count, contact rating, voltage specification, and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMM-109-01-S-D are identified based on strict equivalence across the following critical parameters:

• Connector pitch and position count: 18 positions at 0.079" (2.00mm) mating pitch
• Electrical ratings: 3.2A per contact, 350VAC voltage rating
• Mounting and termination: Through-hole solder termination with push-pull fastening
• Contact specifications: Female socket, square contact shape, beryllium copper material with gold mating finish
• Environmental compliance: UL94 V-0 flammability rating, ROHS3 compliance, operating range -55°C to 125°C
• Insulation system: Liquid Crystal Polymer (LCP) with black color, 0.140" (4.66mm) height

The identified substitutes maintain identical electrical and mechanical interfaces, ensuring direct functional equivalence in board-to-board and cable connection applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with ROHS3 compliance and identical electrical and mechanical specifications. Selection between SMM-109-01-S-D, SMM-109-01-S-D-P, and SMM-109-01-SM-D is determined by assembly process requirements and moisture sensitivity considerations.

SMM-109-01-S-D-P includes pick-and-place features suitable for automated assembly environments. SMM-109-01-SM-D specifies Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. The base SMM-109-01-S-D carries no specified MSL designation.

All parts are functionally equivalent for board-to-board and cable connection applications within the specified electrical and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can SMM-109-01-S-D-P be used as a direct replacement for SMM-109-01-S-D?

A: Yes. Both parts share identical electrical ratings (3.2A per contact, 350VAC), mechanical pitch (0.079" / 2.00mm), position count (18), mounting type (through-hole), and contact specifications. The primary difference is the inclusion of pick-and-place features in the -P variant, which does not affect electrical or mechanical compatibility.

Q: What is the difference between SMM-109-01-S-D and SMM-109-01-SM-D?

A: Both parts are electrically and mechanically identical. The difference lies in moisture sensitivity designation: SMM-109-01-SM-D specifies MSL 1 (Unlimited), meaning it has no moisture sensitivity constraints. The base SMM-109-01-S-D carries no specified MSL. This distinction affects storage and handling protocols but not functional performance.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All three parts maintain the same operating temperature range of -55°C to 125°C and carry UL94 V-0 flammability rating, making them suitable for applications within this thermal envelope.

Q: Do these connectors require specific PCB layout considerations?

A: All three parts use identical through-hole termination with 0.079" (2.00mm) pitch and 2-row configuration. PCB layout requirements are identical across all three part numbers.

Q: Are there inventory or lead-time differences between these substitutes?

A: Inventory levels vary: SMM-109-01-S-D (971 pcs), SMM-109-01-S-D-P (1116 pcs), and SMM-109-01-SM-D (930 pcs). Availability should be verified with your supplier for current lead-time information.
