Parameter Comparison

Engineering Selection Recommendations

Both the SMM-115-01-SM-D and SMM-115-01-S-D are active production parts from Samtec Inc. with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is based on availability and application requirements. The SMM-115-01-S-D offers higher inventory availability at 1045 units compared to 828 units for the main part number. Both connectors meet UL94 V-0 flammability requirements and are suitable for applications requiring 3.2A per contact at 350VAC across the -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the SMM-115-01-SM-D?

A: Substitute connectors must maintain identical specifications for number of positions (30), mating pitch (0.079"), row configuration (2 rows), mounting type (through hole), current rating (3.2A per contact), voltage rating (350VAC), operating temperature range (-55°C ~ 125°C), contact finish (gold), and insulation material (LCP). All these parameters must match exactly for functional equivalence.

Q: Are SMM-115-01-SM-D and SMM-115-01-S-D mechanically compatible?

A: Yes. Both connectors share identical mechanical dimensions, including insulation height (0.140"), contact length (0.120"), and row spacing (0.079"). They are interchangeable in board-to-board and cable applications.

Q: What is the difference between SMM-115-01-SM-D and SMM-115-01-S-D?

A: Both parts are from the Tiger Eye™ SMM series with identical electrical and mechanical specifications. The designation difference reflects internal Samtec product line categorization but does not affect functional performance or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both SMM-115-01-SM-D and SMM-115-01-S-D are ROHS3 compliant with MSL rating of 1 (Unlimited), suitable for applications with RoHS requirements.

Q: What is the current and voltage rating for these connectors?

A: Both connectors are rated for 3.2A per contact and 350VAC maximum voltage, with an operating temperature range of -55°C to 125°C.
