Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLM-109-01-G-D is determined by strict alignment of the following parameters: connector type (receptacle), position count (18), mating pitch (0.050"), row configuration (2 rows), row spacing (0.100"), mounting method (through hole), termination type (solder), contact type (forked), mating contact finish (gold), board-to-board style, and push-pull fastening. The HRS-2B-18-GA from Adam Tech meets all these core electrical and mechanical criteria, establishing it as a valid substitute within the rectangular connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the SLM-109-01-G-D and HRS-2B-18-GA are active production components with ROHS3 compliance and MSL 1 rating. Selection between these parts should account for operating temperature requirements: the SLM-109-01-G-D supports -55°C to 125°C operation, while the HRS-2B-18-GA operates within -40°C to 105°C. For applications requiring the full temperature range of the original specification, the SLM-109-01-G-D is the appropriate choice. The HRS-2B-18-GA is suitable for applications within its specified temperature envelope. Both connectors share identical mating pitch, row configuration, contact geometry, and fastening mechanism, ensuring mechanical and electrical interchangeability within their respective operating parameters.

Frequently Asked Questions (FAQ)

Q: What determines if HRS-2B-18-GA can substitute for SLM-109-01-G-D? A: Substitution is valid when the connector type, position count, mating pitch, row spacing, mounting method, termination type, contact type, contact finish, style, and fastening mechanism are identical. Both parts meet these criteria.

Q: Are there differences in insulation material between these connectors? A: Yes. The SLM-109-01-G-D uses Liquid Crystal Polymer (LCP) insulation, while the HRS-2B-18-GA uses Thermoplastic insulation. Both materials are suitable for their respective operating temperature ranges.

Q: What is the temperature operating range difference? A: The SLM-109-01-G-D operates from -55°C to 125°C, while the HRS-2B-18-GA operates from -40°C to 105°C. Applications requiring the full lower temperature limit of -55°C must use the SLM-109-01-G-D.

Q: Are both parts RoHS compliant? A: Yes, both the SLM-109-01-G-D and HRS-2B-18-GA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Do these connectors have identical contact post specifications? A: Contact post length differs slightly: SLM-109-01-G-D has 0.115" (2.92mm) post length, while HRS-2B-18-GA has 0.118" (3.00mm). Both are suitable for standard through-hole PCB applications with typical copper thickness.
