SFW8S-2STME1 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SFW8S-2STME1 is an 8-position FFC/FPC vertical connector with 1.00mm pitch, designed for surface mount applications. This connector features a slide lock mechanism, zero insertion force (ZIF) operation, and solder termination. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and repair applications.

Substitute Part Grouping Explanation

Substitution eligibility for the SFW8S-2STME1 is determined by the following critical parameters:

Connector Position Count: Must be 8 positions
Pitch Specification: Must be 0.039" (1.00mm)
Mounting Configuration: Must be surface mount
Connector Orientation: Must be vertical, 1-sided contacts
Voltage & Current Ratings: Must support minimum 100V and 1A

Engineering Selection Recommendations

The SFW8S-2STME1LF is the direct active equivalent for the obsolete SFW8S-2STME1. Selection of the substitute part is based on the following engineering factors:

Product Status: The SFW8S-2STME1LF maintains active production status, ensuring long-term supply chain availability and manufacturing support compared to the obsolete main part.

Regulatory Compliance: The SFW8S-2STME1LF achieves RoHS compliance and REACH affected status, meeting current environmental and regulatory requirements. The main part is RoHS non-compliant, which may restrict use in regulated applications.

Operating Temperature Enhancement: The substitute part extends the upper operating temperature limit to 105°C, compared to 85°C for the main part, providing improved thermal margin for demanding applications.

Electrical & Mechanical Equivalence: Both parts maintain identical electrical ratings (100V, 1A), mechanical dimensions (8 positions, 1.00mm pitch, 5.30mm height), contact materials, and flammability certification (UL94 V-0).

Termination Difference: The main part uses solder termination, while the substitute uses kinked pin termination. This represents a manufacturing process variation within the same connector family and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SFW8S-2STME1LF be used as a direct replacement for SFW8S-2STME1 in existing designs?

A: Yes. Both parts share identical position count (8), pitch (1.00mm), mounting type (surface mount), voltage rating (100V), current rating (1A), and flammability certification (UL94 V-0). The substitute part is mechanically and electrically compatible with the original design.

Q: What is the difference between solder termination and kinked pin termination?

A: Solder termination (main part) and kinked pin termination (substitute) are manufacturing process variations for surface mount attachment. Both achieve equivalent electrical and mechanical connections to the PCB. The kinked pin design in the substitute part is a standard alternative within the SFW connector series.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: No. The SFW8S-2STME1LF extends the upper temperature limit to 105°C, which is a performance enhancement. If the original design operates within -55°C ~ 85°C, the substitute part will perform identically within that range and provides additional thermal margin.

Q: What is the packaging difference between the main part and substitute?

A: The main part packaging is not specified. The substitute part (SFW8S-2STME1LF) is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount production.

Q: Are there any compliance differences between the two parts?

A: Yes. The SFW8S-2STME1LF is RoHS compliant and REACH affected, while the main part is RoHS non-compliant and REACH unaffected. For applications requiring RoHS compliance, the substitute part is the appropriate selection.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
