Key Parameters

Substitute Part Grouping Explanation

Substitution of the XMCO-323IBBC is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Manufacturer: American Zettler (same manufacturer ensures design compatibility)
• Series: XMC0 (same product family)
• Contact Form: 3PST-NO (3 Form A) (identical switching configuration)
• Coil Voltage: 208 ~ 240VAC (identical operating voltage range)
• Switching Voltage: 600VAC - Max (identical maximum switching voltage)
• Mounting Type: Chassis Mount (identical physical mounting)
• Termination Style: Screw Terminal (identical connection method)
• Operating Temperature: -25°C ~ 70°C (identical thermal operating range)
• Contact Material: Silver Tin Oxide (AgSnO) (identical contact composition)
• Moisture Sensitivity Level: 1 (Unlimited) (identical environmental rating)

Allowable Variation:

• Contact Rating (Current): The substitute part may exceed the original rating. The XMC0-403IC is rated for 40A, which is higher than the original 32A specification. This represents an upward-compatible substitution suitable for applications requiring equal or lower current capacity.

Parameter Comparison

Engineering Selection Recommendations

The XMC0-403IC serves as a direct substitute for the XMCO-323IBBC based on electrical and mechanical parameter alignment within the XMC0 series. The substitute part maintains identical coil voltage, contact configuration, switching voltage rating, mounting method, and termination style. The increased current rating of 40A compared to the original 32A represents an upward-compatible substitution suitable for applications operating at or below the original 32A specification.

The XMC0-403IC holds Active product status, ensuring ongoing availability and manufacturing support. The substitute part carries RoHS3 compliance and REACH Unaffected status, providing regulatory alignment for current industrial applications. Both parts share identical ECCN (EAR99) and HTSUS (8536.49.0065) classifications, confirming trade compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the XMC0-403IC replace the XMCO-323IBBC in existing installations?

A: Yes. The XMC0-403IC is electrically and mechanically compatible with the XMCO-323IBBC. Both parts operate on 208–240VAC coil voltage, feature identical 3PST-NO contact configuration, and use screw terminal connections. The substitute part's 40A current rating accommodates applications designed for the original 32A specification.

Q: What is the significance of the higher current rating on the substitute part?

A: The XMC0-403IC is rated for 40A versus the original 32A. This higher rating does not affect compatibility in applications requiring 32A or less. The substitute part is suitable for circuits operating within or below the original design current specification.

Q: Are there packaging differences between these parts?

A: The XMCO-323IBBC is specified with packaging listed as a dash (–), while the XMC0-403IC is supplied in Bulk packaging. Both parts are identical in form factor and mounting configuration. Packaging designation reflects distribution format only and does not affect electrical or mechanical compatibility.

Q: Why is the original part listed as obsolete?

A: The XMCO-323IBBC is classified as obsolete, indicating it is no longer in active production. The XMC0-403IC, as an Active product within the same XMC0 series, provides continued access to functionally equivalent relay contactor technology with current manufacturing support.

Q: Are there compliance differences between the two parts?

A: The XMC0-403IC includes RoHS3 compliance and REACH Unaffected status documentation. Both parts share identical ECCN and HTSUS classifications. The substitute part's compliance certifications align with current regulatory requirements for industrial relay contactors.

Q: Do both parts use the same contact material?

A: Yes. Both the XMCO-323IBBC and XMC0-403IC feature Silver Tin Oxide (AgSnO) contact material, ensuring identical electrical performance and contact reliability characteristics.
