SLM-119-01-G-S Equivalent & Substitute Parts

Part Overview

The SLM-119-01-G-S is a 19-position receptacle connector manufactured by Samtec Inc., designed for board-to-board applications with 0.050" (1.27mm) pitch spacing. This connector features through-hole solder termination, gold-plated forked contacts, and operates across -55°C to 125°C. The part is currently active in production with 1055 units in stock and carries ROHS3 compliance certification.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when alternative sourcing is required for cost optimization, or when supply chain diversification is needed for production continuity.

Key Parameters

Substitute Part Grouping Explanation

The HRS-1B-19-GA from Adam Tech qualifies as a substitute based on the following critical parameters that determine functional interchangeability:

• Connector Type & Position Count: Both are 19-position receptacle connectors
• Pitch Specification: Both maintain 0.050" (1.27mm) mating pitch
• Contact Configuration: Both feature forked contacts with rectangular shape
• Mounting & Termination: Both use through-hole solder termination
• Style & Fastening: Both are board-to-board connectors with push-pull fastening
• Contact Material & Finish: Both use phosphor bronze contacts with gold plating on mating surfaces
• Compliance: Both are ROHS3 compliant

Substitution is valid where the mechanical envelope and electrical interface requirements align with these core parameters. Variations in insulation material (LCP vs. Thermoplastic), contact finish thickness specifications, and operating temperature ranges represent design differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status and ROHS3 compliance, supporting long-term availability and regulatory alignment. The SLM-119-01-G-S offers an extended operating temperature range (-55°C to 125°C) compared to the HRS-1B-19-GA (-40°C to 105°C), making it suitable for applications requiring broader thermal performance. The SLM-119-01-G-S uses Liquid Crystal Polymer insulation, while the HRS-1B-19-GA uses Thermoplastic insulation; material selection depends on specific environmental and mechanical stress requirements.

Mechanical dimensions show minor variations: the HRS-1B-19-GA has slightly greater insulation height (0.181" vs. 0.180") and longer contact post length (0.118" vs. 0.115"), which may affect PCB layout and mating depth considerations. Contact finish thickness differs, with the SLM-119-01-G-S specifying discrete values (20.0µin mating, 3.00µin post) versus flash plating on the HRS-1B-19-GA.

Selection should be based on application-specific thermal requirements, PCB design constraints, and environmental exposure conditions.

Frequently Asked Questions (FAQ)

Q: Can HRS-1B-19-GA directly replace SLM-119-01-G-S in existing designs?

A: Mechanical and electrical interfaces are compatible based on matching pitch, position count, contact type, and termination method. However, verify that your application's operating temperature range falls within -40°C to 105°C (HRS-1B-19-GA limit) and that insulation material compatibility with your environment is acceptable.

Q: What are the key differences between these two connectors?

A: Primary differences include operating temperature range (SLM-119-01-G-S: -55°C to 125°C vs. HRS-1B-19-GA: -40°C to 105°C), insulation material (LCP vs. Thermoplastic), and contact finish specifications (discrete thickness vs. flash plating). Mechanical envelope dimensions show minor variations in insulation height and contact post length.

Q: Are both parts RoHS compliant?

A: Yes, both SLM-119-01-G-S and HRS-1B-19-GA are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, supporting standard manufacturing and storage conditions.

Q: How do the contact finish specifications affect performance?

A: The SLM-119-01-G-S specifies defined gold plating thickness (20.0µin mating, 3.00µin post), while the HRS-1B-19-GA uses flash plating. Both provide gold contact surfaces for reliable mating; thickness differences may affect contact wear characteristics and service life under high-cycle mating applications.

Q: What packaging format is available for both parts?

A: Both connectors are supplied in tube packaging, suitable for standard component handling and automated assembly processes.
