SFM-105-01-S-D Equivalent & Substitute Parts

Part Overview

The SFM-105-01-S-D is a 10-position receptacle connector manufactured by Samtec Inc. from the Tiger Eye™ SFM series. This connector features a 0.050" (1.27mm) pitch, through-hole solder termination, and gold-plated mating contacts rated for 3.2A per contact at 250VAC. The product is active and widely available with 755 units in stock. Alternative components may be required due to design constraints, supply chain considerations, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFM-105-01-S-D is evaluated based on the following critical parameters that must align for functional compatibility:

Mandatory Matching Parameters:

• Number of Positions: 10
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold

Acceptable Variation Parameters:

• Connector Type: Receptacle or Header (both board-to-board compatible)
• Contact Material: Beryllium Copper or Phosphor Bronze (both suitable for 0.050" pitch applications)
• Insulation Material: Liquid Crystal Polymer (LCP) for both
• RoHS Compliance: ROHS3 for both

The substitute part LPPB052CFFN-RC from Sullins Connector Solutions meets the mandatory matching criteria. However, differences exist in current rating (1A vs. 3.2A), operating temperature range (-40°C ~ 125°C vs. -55°C ~ 125°C), and contact material composition.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-105-01-S-D and LPPB052CFFN-RC are active products with ROHS3 compliance and REACH unaffected status, making them suitable for current regulatory environments. The primary distinction lies in electrical performance specifications.

The SFM-105-01-S-D supports 3.2A per contact and operates across -55°C to 125°C. The LPPB052CFFN-RC is rated for 1A per contact with an operating range of -40°C to 125°C. Selection between these components depends on application current requirements and minimum operating temperature specifications. Applications requiring currents exceeding 1A per contact or operation below -40°C must use the SFM-105-01-S-D. Applications within 1A per contact and above -40°C may use either component, provided mechanical and electrical interface compatibility is confirmed.

Frequently Asked Questions (FAQ)

Q: Can LPPB052CFFN-RC directly replace SFM-105-01-S-D in all applications?

A: No. While both connectors share identical pitch (0.050"), row count (2), and position count (10), the LPPB052CFFN-RC has a lower current rating (1A vs. 3.2A per contact) and a narrower operating temperature range (-40°C to 125°C vs. -55°C to 125°C). Substitution is valid only when application current does not exceed 1A per contact and minimum operating temperature remains above -40°C.

Q: What is the difference between a Receptacle and Header connector in this context?

A: The SFM-105-01-S-D is a receptacle (female socket), while the LPPB052CFFN-RC is a header (male pin). Both are board-to-board connectors with identical mating pitch and row spacing. The choice between receptacle and header depends on the complementary connector type on the mating board.

Q: Are both parts RoHS compliant?

A: Yes. Both SFM-105-01-S-D and LPPB052CFFN-RC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of contact material differences (Beryllium Copper vs. Phosphor Bronze)?

A: Both materials are suitable for 0.050" pitch connectors. Beryllium Copper (SFM-105-01-S-D) and Phosphor Bronze (LPPB052CFFN-RC) provide adequate contact retention and electrical conductivity for this connector class. Material selection does not affect substitution eligibility when electrical and mechanical parameters align.

Q: Can I use LPPB052CFFN-RC in high-current applications?

A: No. The LPPB052CFFN-RC is rated for 1A per contact maximum. Applications requiring 3.2A per contact must use the SFM-105-01-S-D or equivalent high-current rated components.
