SLM-108-01-L-S Equivalent & Substitute Parts

Part Overview

The SLM-108-01-L-S is an 8-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 mating contacts, and forked contact geometry. The part is currently active in production with 1002 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where connector type variation is acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLM-108-01-L-S is determined by the following critical parameters:

• Number of positions: 8
• Pitch spacing: 0.050" (1.27mm)
• Mounting type: Through hole
• Termination method: Solder
• Contact finish: Gold
• Insulation material: Liquid Crystal Polymer (LCP)
• RoHS compliance: ROHS3 Compliant

The LPPB081NFFN-RC from Sullins Connector Solutions meets these core electrical and mechanical requirements. While the connector type differs (header vs. receptacle) and contact geometry varies (square vs. forked), the mating pitch, position count, through-hole mounting, solder termination, gold contact finish, LCP insulation, and RoHS3 compliance enable functional equivalence in board-to-board interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SLM-108-01-L-S and LPPB081NFFN-RC are active production components with ROHS3 compliance and MSL 1 rating. The primary distinction is the operating temperature range: the SLM-108-01-L-S supports -55°C to 125°C, while the LPPB081NFFN-RC operates from -40°C to 105°C. Selection between these parts should be based on the application's thermal requirements. Both connectors meet the core electrical and mechanical specifications for 0.050" pitch, 8-position board-to-board interconnect applications with solder termination and gold contact finish. The substitute part is suitable for applications within its specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can the LPPB081NFFN-RC directly replace the SLM-108-01-L-S?

A: The LPPB081NFFN-RC shares the same mating pitch (0.050"), position count (8), mounting type (through hole), termination method (solder), contact finish (gold), and insulation material (LCP). However, the connector types differ: the SLM-108-01-L-S is a receptacle with forked contacts, while the LPPB081NFFN-RC is a header with female socket contacts. Substitution is valid when the application's connector topology accommodates this difference.

Q: What are the temperature operating limits for each part?

A: The SLM-108-01-L-S operates from -55°C to 125°C. The LPPB081NFFN-RC operates from -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the SLM-108-01-L-S.

Q: Are both parts RoHS compliant?

A: Yes, both the SLM-108-01-L-S and LPPB081NFFN-RC are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: What is the difference in insulation height between these connectors?

A: The SLM-108-01-L-S has an insulation height of 0.180" (4.57mm), while the LPPB081NFFN-RC measures 0.177" (4.50mm). This 0.003" (0.07mm) difference is negligible for most board-to-board applications.

Q: Do both connectors use the same contact material?

A: Yes, both connectors use phosphor bronze contacts with gold plating on the mating surface. The SLM-108-01-L-S has tin-plated posts, while the LPPB081NFFN-RC has gold-plated posts.
