Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6BS1-B are selected based on the following critical parameters that define functional equivalence:

Primary Compatibility Criteria:

• Circuit configuration: SPDT topology maintained across all substitutes
• Mounting type: Chassis mount configuration required
• Termination style: Screw terminal connection required
• Voltage rating: 125V AC minimum requirement
• Actuator type: Round pin plunger or compatible mechanical interface

Substitution Logic: The three Omron Z-series switches (Z-15GK355-B, Z-15GK55-B, Z-15GW22-B) meet the core electrical and mechanical requirements for substitution. All three maintain SPDT circuit configuration, chassis mount design, and screw terminal termination. The Omron switches provide equal or superior current ratings (15A AC) and voltage compatibility (125V AC). While operating force characteristics differ, the mechanical interface remains compatible with round pin plunger actuation or lever/roller variants. All substitute parts are active products with current manufacturing status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 6BS1-B is classified as obsolete. All three Omron substitute parts (Z-15GK355-B, Z-15GK55-B, Z-15GW22-B) maintain active product status with current manufacturing support and documented compliance certifications.

Compliance and Certification: All substitute parts exceed the compliance profile of the original component. The Honeywell 6BS1-B carries RoHS Compliant status. The Omron substitutes provide ROHS3 Compliant certification, representing enhanced environmental compliance standards. Z-15GK355-B and Z-15GK55-B carry REACH Affected designation, while Z-15GW22-B is REACH Unaffected. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Electrical Performance: All substitute parts provide equal or superior current ratings (15A AC versus 10A AC original) and maintain 125V AC voltage compatibility. DC voltage ratings on substitutes are reduced to 30V compared to the original 125V DC rating. Applications requiring DC operation above 30V require evaluation of circuit requirements.

Mechanical Interface: Z-15GK355-B and Z-15GK55-B maintain round pin plunger actuator configuration identical to the original. Z-15GW22-B features lever/roller actuator design, requiring mechanical interface verification for specific mounting applications. Operating force values differ significantly across all substitutes, necessitating force requirement analysis for the target application.

Packaging and Availability: Z-15GK355-B and Z-15GW22-B are supplied in Tray packaging. Z-15GK55-B is supplied in Bulk packaging. Selection should align with procurement and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the Omron Z-15GK355-B directly replace the Honeywell 6BS1-B in all applications?

A: The Z-15GK355-B maintains SPDT circuit configuration, chassis mount design, screw terminal termination, and 125V AC voltage rating. However, DC voltage rating is reduced from 125V to 30V. Applications operating at DC voltages above 30V require circuit redesign. Operating force is reduced from 992gf to 540gf, which may affect mechanical actuation characteristics in force-sensitive applications.

Q: What is the difference between Z-15GK355-B and Z-15GK55-B?

A: Both parts share identical electrical specifications (15A AC, 6A DC, 125V AC, 30V DC) and mechanical characteristics (540gf operating force, 114gf release force). The primary differences are operating position (1.488" versus 1.110"), pretravel (0.094" versus 0.090"), overtravel (0.138" versus 0.062"), and packaging (Tray versus Bulk). Selection depends on specific mechanical stroke requirements and procurement format.

Q: When should Z-15GW22-B be selected instead of the pin plunger variants?

A: Z-15GW22-B features a lever/roller actuator with significantly lower operating force (160gf) and release force (42gf) compared to pin plunger designs. This configuration is suitable for applications requiring lighter actuation force or lever-based mechanical interfaces. The lever/roller design operates across a wider temperature range (-25°C to 80°C versus -15°C to 80°C) and carries lower mechanical life rating (10,000,000 cycles versus 20,000,000 cycles).

Q: Are all substitute parts RoHS compliant?

A: Yes. The original 6BS1-B carries RoHS Compliant status. All three Omron substitutes carry ROHS3 Compliant certification, representing current environmental compliance standards. ROHS3 compliance encompasses RoHS 2 and RoHS 3 directives.

Q: What packaging options are available for these substitute parts?

A: Z-15GK355-B is supplied in Tray packaging (1009 pcs available). Z-15GK55-B is supplied in Bulk packaging (988 pcs available). Z-15GW22-B is supplied in Tray packaging (3640 pcs available). Packaging selection should align with assembly process requirements and inventory management practices.

Q: Do the substitute parts have documented electrical and mechanical life specifications?

A: Yes. All three Omron substitutes provide electrical life ratings of 500,000 cycles. Mechanical life ratings are 20,000,000 cycles for Z-15GK355-B and Z-15GK55-B, and 10,000,000 cycles for Z-15GW22-B. The original 6BS1-B does not provide these specifications in available documentation.

Q: What is the significance of REACH status on the substitute parts?

A: Z-15GK355-B and Z-15GK55-B carry REACH Affected designation, indicating these parts contain substances of concern regulated under REACH legislation. Z-15GW22-B is REACH Unaffected. For applications subject to REACH compliance requirements, Z-15GW22-B may present simplified regulatory documentation requirements.
