Substitute Part Grouping Explanation

The substitute parts 2800838 and 2800860 are parametric equivalents to the main part 2800849. Substitution is based on identical electrical and mechanical specifications: thermal magnetic breaker type, 3A current rating, 277V AC and 50V DC voltage ratings, single-pole configuration, slide switch actuation, and holder mounting. All three parts are manufactured by Phoenix Contact within the CB series and maintain ROHS3 compliance. The key parameters determining substitutability are current rating, voltage ratings (both AC and DC), breaker type, pole count, and actuator type. These parameters must remain constant across all equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2800849, 2800838, and 2800860—are functionally equivalent and interchangeable based on electrical and mechanical parameters. Selection between these parts should be based on compliance requirements and regulatory status. Part 2800838 is REACH Unaffected, making it suitable for applications with strict REACH compliance requirements. Parts 2800849 and 2800860 are both REACH Affected and should be selected when REACH compliance status is not a constraint. All parts maintain ROHS3 compliance and EAR99 export classification. Inventory availability should be considered as a secondary factor: 2800849 has 1122 units, 2800838 has 1058 units, and 2800860 has 982 units in stock.

Frequently Asked Questions (FAQ)

Q: Can part 2800838 be used as a direct replacement for 2800849? A: Yes. Both parts are parametric equivalents with identical electrical ratings (3A, 277V AC, 50V DC), breaker type (thermal magnetic), pole count (1), actuator type (slide switch), and mounting configuration (holder). The primary difference is REACH compliance status.

Q: What is the significance of REACH status in part selection? A: REACH status indicates regulatory compliance for chemical substance restrictions in the European Union. Part 2800838 is REACH Unaffected, while 2800849 and 2800860 are REACH Affected. Selection depends on end-use application and regional regulatory requirements.

Q: Are there any mechanical or dimensional differences between these parts? A: No mechanical or dimensional differences are specified in the provided parameters. All three parts share identical mounting type (holder), actuator type (slide switch), and series designation (CB).

Q: Can these parts be used interchangeably in the same circuit design? A: Yes, provided that REACH and other regulatory requirements for your application are satisfied. The electrical specifications—current rating, voltage ratings, and breaker characteristics—are identical across all three parts.

Q: What packaging format is used for these parts? A: All three parts are supplied in bulk packaging.
