Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FFC/FPC connectors is determined by strict alignment of electrical and mechanical parameters. The following criteria establish compatibility:

Critical Parameters for Substitution:

• Number of positions (26)
• Pitch specification (1.00mm)
• Mounting type (Surface Mount)
• Connector orientation (Vertical - 1 Sided)
• Voltage rating (100V minimum)
• Current rating (1A minimum)
• Termination method (Solder)
• Housing and actuator materials (Thermoplastic, Glass Filled)
• Flammability rating (UL94 V-0)

The SFW26S-2STE1LF qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the SFW series.

Parameter Comparison

Engineering Selection Recommendations

The SFW26S-2STE1LF is the appropriate substitute for the obsolete SFW26S-2STE1. Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring direct functional compatibility in existing designs.

The SFW26S-2STE1LF offers additional advantages: active product status ensures continued availability and manufacturing support, RoHS compliance aligns with current regulatory requirements, and the extended operating temperature range (-55°C ~ 105°C versus -55°C ~ 85°C) provides broader thermal performance capability. The Tape & Reel packaging format supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SFW26S-2STE1LF be used as a direct replacement for SFW26S-2STE1?

A: Yes. Both connectors share identical position count (26), pitch (1.00mm), voltage rating (100V), current rating (1A), mounting type (Surface Mount), and contact configuration. Electrical and mechanical compatibility is established.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active), RoHS compliance status, operating temperature upper limit (85°C versus 105°C), and packaging format (bulk versus Tape & Reel). The SFW26S-2STE1LF also lacks the slide lock feature and specified cable end type parameters present in the original part.

Q: Does the extended temperature range of SFW26S-2STE1LF affect compatibility?

A: No. The extended range (-55°C ~ 105°C) is a superset of the original specification (-55°C ~ 85°C), ensuring compatibility across all original operating conditions.

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and supply chain consideration. The SFW26S-2STE1LF meets current environmental standards, while the original part does not. Selection depends on application requirements and regional regulations.

Q: What packaging format should be selected?

A: The SFW26S-2STE1LF is supplied in Tape & Reel format, suitable for automated pick-and-place assembly. The original part was supplied in bulk packaging. Tape & Reel format is standard for surface mount production environments.
