Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB4/1/5S is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current rating (20A), voltage rating (300V), and wire gauge acceptance (12-24 AWG) must remain unchanged
• Mechanical Configuration: Single-circuit barrier block design with screw termination
• Material Specification: Ceramic insulation material
• Thermal Capability: Operating temperature range of -40°C to 600°C
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The CB4/1 qualifies as a direct substitute based on identical electrical ratings, mechanical design, material composition, and regulatory certifications. The primary distinction is packaging: CB4/1/5S is supplied as a 5-piece set, while CB4/1 is available in bulk packaging. This difference does not affect functional equivalence for single-unit applications.

Parameter Comparison

Engineering Selection Recommendations

The CB4/1 is a valid substitute for the CB4/1/5S when application requirements are met by the following conditions:

• The circuit configuration, current capacity, and voltage rating of the application match the 1-circuit, 20A, 300V specification
• Wire gauge requirements fall within the 12-24 AWG range
• Operating temperature conditions remain within -40°C to 600°C
• ROHS3 compliance and REACH unaffected status satisfy regulatory requirements for the end application

Selection between CB4/1/5S and CB4/1 should be based on procurement quantity requirements and packaging preferences. Both parts maintain identical electrical and mechanical performance characteristics. The CB4/1/5S packaging format is appropriate for applications requiring small quantities or pre-assembled sets, while CB4/1 bulk packaging is suitable for higher-volume procurement or integration into larger assemblies.

Frequently Asked Questions (FAQ)

Q: Can CB4/1 be used as a direct replacement for CB4/1/5S?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical current rating (20A), voltage rating (300V), wire gauge acceptance (12-24 AWG), ceramic insulation material, and operating temperature range (-40°C to 600°C). The difference is packaging format only.

Q: What is the primary difference between CB4/1/5S and CB4/1?

A: CB4/1/5S is supplied as a 5-piece set, while CB4/1 is supplied in bulk packaging. Functional specifications are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both CB4/1/5S and CB4/1 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What wire gauges are compatible with these terminal blocks?

A: Both parts accept wire gauges from 12 AWG to 24 AWG, providing flexibility for various conductor sizes within this range.

Q: What is the maximum operating temperature for these components?

A: Both parts are rated for continuous operation up to 600°C, with a minimum operating temperature of -40°C.
