Key Parameters

Substitute Part Grouping Explanation

Substitution for the SFW5S-2STME1 is determined by the following critical parameters that must remain constant:

• Number of Positions: 5 (electrical requirement)
• Pitch: 0.039" (1.00mm) (mechanical compatibility)
• Mounting Type: Surface Mount (assembly requirement)
• Connector Type: Contacts, Vertical - 1 Sided (form factor)
• Voltage Rating: 100V (electrical specification)
• Current Rating: 1A (electrical specification)
• Termination: Solder (assembly process)

The identified substitute part SFW5S-2STME1LF maintains all critical parameters while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SFW5S-2STME1LF is the direct substitute for the obsolete SFW5S-2STME1. Key advantages of the substitute include:

• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain stability.
• RoHS Compliance: The substitute meets RoHS requirements, whereas the original part is non-compliant. This is significant for applications subject to RoHS regulations.
• Extended Operating Temperature Range: The substitute supports -55°C to 105°C compared to -55°C to 85°C for the original, providing broader thermal operating capability.
• Improved Packaging: Tape & Reel packaging is standard for production environments and facilitates automated assembly processes.

All critical electrical and mechanical parameters remain identical, ensuring direct functional compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can SFW5S-2STME1LF be used as a direct replacement for SFW5S-2STME1?

A: Yes. Both parts share identical position count (5), pitch (1.00mm), mounting type (surface mount), voltage rating (100V), current rating (1A), and physical height (5.30mm). The substitute maintains full electrical and mechanical compatibility.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. compliant), operating temperature range (-55°C to 85°C vs. -55°C to 105°C), and packaging format (bulk vs. tape & reel). Functionally, both parts are equivalent.

Q: Why is the operating temperature range different?

A: The substitute part supports an extended upper temperature limit of 105°C compared to 85°C for the original. This expanded range does not affect compatibility; applications operating within the original -55°C to 85°C range will function identically with either part.

Q: Does packaging affect electrical performance?

A: No. Tape & Reel packaging is a supply and assembly convenience format. It does not alter the electrical or mechanical characteristics of the connector itself.

Q: Is RoHS compliance a functional requirement?

A: RoHS compliance is a regulatory and environmental requirement, not a functional electrical specification. The substitute's RoHS compliance status may be mandatory depending on application jurisdiction and customer requirements.

Q: Are there any compatibility concerns with PCB layout or assembly?

A: No. Both parts have identical mounting footprints, height above board (5.30mm), and surface mount requirements. Existing PCB designs require no modification.
