Engineering Selection Recommendations

The SFW26S-2STME1LF is the direct substitute for the obsolete SFW26S-2STME1. Both parts share identical electrical ratings, mechanical dimensions, and contact configurations. The substitute offers the following advantages:

Active Product Status: SFW26S-2STME1LF is actively manufactured and supported, ensuring long-term availability and supply chain stability.
RoHS Compliance: The substitute meets RoHS requirements, whereas the original part does not, supporting regulatory compliance in new designs and procurement.
Extended Operating Temperature: The substitute supports operation up to 105°C compared to 85°C for the original, providing additional thermal margin in demanding applications.
Packaging: Available in Tape & Reel format, facilitating automated assembly processes.

Both parts maintain identical mechanical fit, electrical performance, and environmental ratings (UL94 V-0, MSL 1). The termination method differs (solder vs. kinked pin), but both are surface mount compatible. Selection should be based on production requirements, compliance mandates, and supply availability.

Frequently Asked Questions (FAQ)

Q: Can SFW26S-2STME1LF be used as a direct replacement for SFW26S-2STME1?

A: Yes. Both parts maintain identical 26-position configuration, 1.00mm pitch, 100V/1A electrical ratings, 0.209" height above board, and UL94 V-0 flammability rating. The substitute is mechanically and electrically compatible for surface mount applications.

Q: What is the difference in termination between these parts?

A: SFW26S-2STME1 uses solder termination, while SFW26S-2STME1LF uses kinked pin termination. Both are surface mount compatible and suitable for PCB assembly.

Q: Does the extended operating temperature range of SFW26S-2STME1LF affect compatibility?

A: No. The substitute's extended range (-55°C to 105°C) is a superset of the original (-55°C to 85°C). Applications operating within the original temperature range remain fully compatible.

Q: Is RoHS compliance a functional difference?

A: RoHS compliance is a regulatory and material composition characteristic, not a functional one. Both parts perform identically in circuit operation. The substitute's RoHS compliance is advantageous for new designs and markets with regulatory requirements.

Q: What packaging formats are available?

A: SFW26S-2STME1 packaging is not specified in available data. SFW26S-2STME1LF is supplied in Tape & Reel format, standard for automated surface mount assembly.

Q: Are there any locking feature differences?

A: SFW26S-2STME1 includes a slide lock feature. SFW26S-2STME1LF does not specify a locking feature. Verify mechanical retention requirements for your application.

Q: Do both parts have the same mating cycle rating?

A: Yes. Both parts are rated for 20 mating cycles, indicating equivalent mechanical durability.
