SFW11S-2STME1LF Equivalent & Substitute Parts

Part Overview

The SFW11S-2STME1LF is an 11-position FFC/FPC vertical connector manufactured by Amphenol ICC (FCI) with 1.00mm pitch and surface mount termination. This connector is designed for flat flexible cable applications requiring zero insertion force (ZIF) operation. The part is currently in active production status with 856 units in stock.

Finding equivalent and substitute parts becomes necessary when the original part reaches end-of-life, experiences supply constraints, or when design requirements allow for alternative connector solutions that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FFC/FPC connectors is determined by the following critical parameters:

• Number of positions (11 positions required)
• Pitch specification (1.00mm required)
• Mounting type (Surface Mount required)
• Connector orientation (Vertical - 1 Sided required)
• Electrical ratings (Voltage: 100V minimum; Current: 1A minimum)
• Operating temperature range (must encompass or match -55°C ~ 105°C)
• Termination method (Solder required)
• Flat flex type compatibility (FFC/FPC)

The substitute part 0526101133 (Molex Easy-On 52610 series) meets these core substitution criteria with matching position count, pitch, mounting type, and connector orientation. Both parts feature ZIF operation and solder termination suitable for identical PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The SFW11S-2STME1LF is the primary selection for new designs and ongoing production due to its active product status and extended operating temperature range (-55°C ~ 105°C). This part is RoHS Compliant and carries REACH Affected status.

The substitute part 0526101133 (Molex) is classified as obsolete and should not be selected for new designs. However, it remains electrically and mechanically compatible for legacy system maintenance or repair applications where the original part is unavailable. The Molex part exhibits a narrower operating temperature range (-40°C ~ 85°C) and reduced mating cycle rating (30 vs. 20 cycles), which may impact suitability for demanding thermal or high-cycle applications.

Both parts carry identical moisture sensitivity levels (MSL 1) and flammability ratings (UL94 V-0), ensuring equivalent environmental performance in standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0526101133 be used as a direct replacement for the Amphenol ICC SFW11S-2STME1LF?

A: The Molex part is mechanically and electrically compatible for applications operating within -40°C ~ 85°C. However, the Amphenol part supports extended temperature operation to -55°C and 105°C. Verify your application's thermal requirements before substitution.

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

A: The primary differences are product status (Amphenol is active; Molex is obsolete), operating temperature range (Amphenol: -55°C ~ 105°C; Molex: -40°C ~ 85°C), height above board (Amphenol: 5.30mm; Molex: 5.74mm), and mating cycle rating (Amphenol: 20; Molex: 30). Both share identical pitch, position count, and ZIF functionality.

Q: Are there PCB layout considerations when switching between these parts?

A: Yes. The height above board differs by 0.44mm (Molex is taller). Verify clearance in your enclosure design. Additionally, the FFC/FCB thickness differs (Amphenol: 0.33mm; Molex: 0.30mm), which may affect cable compatibility.

Q: Do both parts meet current RoHS requirements?

A: The Amphenol part is RoHS Compliant. The Molex part is ROHS3 Compliant. Both meet modern RoHS standards and are suitable for EU market applications.

Q: What is the contact finish difference, and does it affect performance?

A: The Amphenol part uses Tin finish; the Molex part uses Tin Bismuth finish. Both provide equivalent electrical performance and corrosion resistance for standard applications. The Tin Bismuth finish may offer slightly improved whisker resistance in high-reliability applications.
