SFMC-112-L2-S-D Equivalent & Substitute Parts

Part Overview

The SFMC-112-L2-S-D is a 24-position receptacle connector manufactured by Samtec Inc. from the Tiger Eye™ SFMC series. This surface mount board-to-board connector features 0.050" (1.27mm) pitch mating with gold-plated contacts rated for 2.9A per contact and operates across -55°C to 125°C. The part is Active status and ROHS3 compliant. Alternative equivalent parts may be required due to inventory constraints, application-specific mechanical requirements, or design flexibility in connector type selection while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The LPPB122NFSP-RC from Sullins Connector Solutions qualifies as a substitute based on the following alignment of critical parameters:

Matching Parameters:

• Number of Positions: 24
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Insulation Color: Black
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• Product Status: Active

The substitute maintains electrical and mechanical compatibility through identical pitch, position count, row configuration, and surface mount termination. Both connectors support push-pull fastening and meet the same flammability and compliance standards.

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-112-L2-S-D and LPPB122NFSP-RC are Active products with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. The primary distinction lies in connector type: the main part is a receptacle while the substitute is a header with top or bottom entry capability. This difference affects board layout and mating strategy but does not compromise electrical or mechanical compatibility when the application accommodates header-type connectors.

The SFMC-112-L2-S-D supports higher current capacity at 2.9A per contact and operates across a wider temperature range (-55°C to 125°C). The LPPB122NFSP-RC is rated for 1A per contact with a minimum operating temperature of -40°C. Selection should be based on application current requirements and thermal environment specifications.

Both parts maintain identical pitch, position count, row spacing, and surface mount termination, ensuring PCB footprint compatibility when connector type substitution is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the LPPB122NFSP-RC directly replace the SFMC-112-L2-S-D on the same PCB?

A: The parts share identical pitch (0.050"), position count (24), row configuration (2 rows), and row spacing (0.050"), allowing the same PCB footprint to accommodate either connector. However, the SFMC-112-L2-S-D is a receptacle while the LPPB122NFSP-RC is a header. The mating connector type must be compatible with the selected part. If the application currently uses a header to mate with the receptacle, substitution to the LPPB122NFSP-RC would require a corresponding receptacle as the mating connector.

Q: What are the current rating differences between these parts?

A: The SFMC-112-L2-S-D is rated for 2.9A per contact, while the LPPB122NFSP-RC is rated for 1A per contact. Applications requiring current levels above 1A per contact must use the SFMC-112-L2-S-D to ensure safe operation within rated specifications.

Q: Are there temperature range differences?

A: Yes. The SFMC-112-L2-S-D operates from -55°C to 125°C, while the LPPB122NFSP-RC operates from -40°C to 125°C. Applications requiring operation below -40°C must use the SFMC-112-L2-S-D.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Both are Active products suitable for current designs.

Q: What is the difference in contact material?

A: The SFMC-112-L2-S-D uses Beryllium Copper contacts with tin post finish, while the LPPB122NFSP-RC uses Phosphor Bronze contacts with gold post finish. Both materials are suitable for the specified pitch and mating cycles with gold-plated mating surfaces.

Q: How do the insulation heights compare?

A: The SFMC-112-L2-S-D has an insulation height of 0.185" (4.70mm), while the LPPB122NFSP-RC is 0.183" (4.65mm). This 0.002" (0.05mm) difference is negligible for most applications and does not affect PCB layout compatibility.
