Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 1301.9318 are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain SPST-NO circuit configuration with 0.05A contact rating. The C&K KSC9 series substitutes are rated for 32VDC, which exceeds the 12VDC requirement of the main part, ensuring electrical compatibility in applications operating at or below 12VDC.

Mechanical Compatibility: All parts feature surface mount gull wing termination, top actuated orientation, and comparable outline dimensions (6.00mm x 6.00mm main part versus 6.20mm x 6.20mm substitutes). Actuator heights are within acceptable tolerance ranges (8.00mm main part versus 7.70mm substitutes).

Regulatory Compliance: All parts are RoHS3 compliant and REACH unaffected, meeting current environmental standards.

Operational Differences: Substitute parts offer enhanced specifications including higher mechanical life (300,000 cycles versus 100,000 cycles), extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C), and improved ingress protection (IP67 versus IP40). Operating force varies across the KSC9 series (170gf, 255gf, 340gf) to accommodate different application requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment with current environmental directives. The C&K KSC9 series substitutes provide enhanced durability through tripled mechanical life ratings (300,000 cycles) and extended operating temperature ranges suitable for industrial applications. The IP67 ingress protection rating offers superior environmental sealing compared to the IP40 rating of the main part.

Selection between KSC921G LFS, KSC931G LFS, and KSC941G LFS should be based on application-specific operating force requirements. The KSC921G LFS (170gf) provides the closest operating force match to the original 160gf specification. The KSC931G LFS (255gf) and KSC941G LFS (340gf) are suitable for applications requiring higher actuation force.

Packaging format differs between the main part (Bulk) and all substitutes (Tape & Reel), which may impact procurement workflows and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can C&K KSC9 series switches replace the SCHURTER 1301.9318 in 12VDC applications?

A: Yes. The C&K KSC9 series switches are rated for 32VDC, which exceeds the 12VDC operating requirement. All substitute parts maintain SPST-NO circuit configuration and 0.05A contact rating, ensuring electrical compatibility.

Q: What are the mechanical differences between the main part and substitutes?

A: The main part features 8.00mm actuator height and 0.25mm switch travel. Substitute parts have 7.70mm actuator height and 0.40mm switch travel. Outline dimensions increase from 6.00mm x 6.00mm to 6.20mm x 6.20mm. These differences require PCB layout verification to ensure mechanical clearance and functional compatibility.

Q: How do operating force ratings differ across the substitute options?

A: The KSC921G LFS provides 170gf (closest to the original 160gf), the KSC931G LFS provides 255gf, and the KSC941G LFS provides 340gf. Operating force selection depends on the tactile feedback and actuation pressure requirements of the end application.

Q: What is the impact of packaging format differences?

A: The main part is supplied in Bulk packaging, while all substitutes are supplied in Tape & Reel (TR) format. This affects component handling, storage, and automated assembly compatibility. Tape & Reel packaging is standard for high-volume surface mount production.

Q: Are all parts compliant with current environmental regulations?

A: Yes. All parts are RoHS3 compliant and REACH unaffected, meeting current environmental standards for electronic component manufacturing and use.

Q: What is the advantage of the extended operating temperature range in substitute parts?

A: Substitute parts operate from -40°C to 85°C compared to the main part's -20°C to 70°C range. This extended range accommodates industrial and automotive applications requiring operation in extreme temperature environments.
