Parameter Comparison

Engineering Selection Recommendations

FCB-205-0124L=M83536/1-024L (Primary Part)

This part is the baseline reference component with active production status and highest current inventory availability. It carries RoHS non-compliant status and REACH Unaffected certification. Selection of this part is appropriate for applications where RoHS compliance is not a design requirement and REACH compliance status is established.

2-1617758-9 (Parametric Equivalent Substitute)

This substitute maintains full electrical and mechanical equivalence to the main part with identical coil voltage, contact configuration, current ratings, and timing specifications. It carries the same RoHS non-compliant and REACH Unaffected status as the main part. Inventory availability is 656 pieces. This part is suitable for direct substitution in applications with identical compliance requirements.

FCB-205-BZ3 (Parametric Equivalent Substitute with Compliance Upgrade)

This substitute maintains full electrical and mechanical equivalence while offering ROHS3 compliance status. REACH status is listed as Vendor Undefined. Inventory availability is 895 pieces. This part is suitable for applications requiring RoHS3 compliance while maintaining all electrical and mechanical performance characteristics of the main part.

Frequently Asked Questions (FAQ)

Q: Can the substitute parts be used interchangeably with the FCB-205-0124L=M83536/1-024L in existing designs?

A: Yes. Both substitute parts (2-1617758-9 and FCB-205-BZ3) maintain identical electrical parameters including 28VDC coil voltage, DPDT contact form, 5 A contact rating, 56 mA coil current, and 4 ms operate/release times. Mechanical compatibility is preserved through identical through-hole mounting, PC pin termination, and hermetic sealing. Direct substitution is supported at the circuit level.

Q: What is the difference between the main part and the FCB-205-BZ3 substitute?

A: The FCB-205-BZ3 substitute is electrically and mechanically identical to the main part FCB-205-0124L=M83536/1-024L. The primary difference is RoHS compliance status: the main part is RoHS non-compliant, while FCB-205-BZ3 is ROHS3 compliant. All other parameters, including coil voltage, contact configuration, current ratings, temperature range, and seal rating, are equivalent.

Q: Are there any compliance considerations when selecting between these parts?

A: Yes. The main part (FCB-205-0124L=M83536/1-024L) and substitute 2-1617758-9 are both RoHS non-compliant with REACH Unaffected status. The FCB-205-BZ3 substitute is ROHS3 compliant but has Vendor Undefined REACH status. Design requirements for RoHS and REACH compliance should determine part selection. All three parts carry EAR99 ECCN classification.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by: 28VDC coil voltage, DPDT (2 Form C) contact form, 5 A contact rating, 56 mA coil current, 500 Ohms coil resistance, 18 VDC must operate voltage, 1.5 VDC must release voltage, and 4 ms operate/release times. All identified substitutes maintain these parameters.

Q: How do the mechanical specifications affect substitution?

A: Mechanical compatibility requires through-hole mounting type, PC pin termination style, hermetic sealing, and -70°C to 125°C operating temperature range. All identified substitutes meet these mechanical requirements, ensuring physical and thermal compatibility in existing circuit board layouts and thermal environments.

Q: What inventory considerations apply to part selection?

A: Current inventory levels are: FCB-205-0124L=M83536/1-024L (1021 pieces), 2-1617758-9 (656 pieces), and FCB-205-BZ3 (895 pieces). Inventory availability may influence procurement decisions when lead times or volume requirements are factors.
