Key Parameters

Substitute Part Grouping Explanation

The XMC0-403ED qualifies as a direct substitute for the XMCO-323EBBD based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Coil voltage: 24VAC
• Contact form: 3PST-NO (3 Form A)
• Switching voltage: 600VAC maximum
• Mounting type: Chassis Mount
• Termination style: Box Lug, Quick Connect - 0.250" (6.3mm)
• Operating temperature range: -25°C ~ 70°C
• Must operate voltage: 19.2 VAC
• Must release voltage: 4.8 VAC
• Contact material: Silver Tin Oxide (AgSnO)
• Moisture sensitivity level: 1 (Unlimited)
• Series: XMC0
• Manufacturer: American Zettler

Distinguishing Parameter:

• Contact rating current: XMC0-403ED is rated for 40A versus the XMCO-323EBBD at 32A

The higher current rating of the substitute part provides enhanced capacity while maintaining all other functional and mechanical specifications, making it suitable for applications requiring the original 32A specification.

Parameter Comparison

Engineering Selection Recommendations

The XMC0-403ED is the direct substitute for the obsolete XMCO-323EBBD. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. Both components share identical electrical specifications for coil voltage, contact configuration, switching voltage, and operating parameters. The XMC0-403ED provides a higher current rating of 40A compared to the original 32A specification, offering increased capacity margin within the same physical and electrical envelope. Both parts carry identical export control classification (EAR99) and tariff codes (8536.41.0045), confirming regulatory equivalence. The substitute part is available in tray packaging with 1139 units in stock, compared to the obsolete part with 798 units remaining.

Frequently Asked Questions (FAQ)

Q: Can the XMC0-403ED directly replace the XMCO-323EBBD in existing applications?

A: Yes. The XMC0-403ED is a direct substitute with identical coil voltage (24VAC), contact form (3PST-NO), switching voltage (600VAC maximum), mounting type (Chassis Mount), and termination style (Box Lug, Quick Connect - 0.250"). All electrical operating parameters, including must-operate and must-release voltages, are identical.

Q: What is the significance of the higher 40A current rating on the XMC0-403ED?

A: The XMC0-403ED is rated for 40A versus the original 32A specification. This higher rating provides additional capacity margin and does not create incompatibility. Applications operating at or below 32A will function identically with the substitute part.

Q: Are the physical dimensions and mounting compatible?

A: Yes. Both parts are Chassis Mount relays with identical termination style (Box Lug, Quick Connect - 0.250" / 6.3mm), ensuring mechanical compatibility in existing installations.

Q: What is the difference in packaging between the two parts?

A: The XMCO-323EBBD is supplied with standard packaging, while the XMC0-403ED is supplied in tray packaging. This difference does not affect component functionality or electrical performance.

Q: Are there any regulatory or compliance differences?

A: No. Both parts carry identical export control classification (EAR99) and tariff codes (8536.41.0045), confirming full regulatory equivalence.

Q: Why is the XMCO-323EBBD classified as obsolete?

A: The XMCO-323EBBD is no longer in active production. The XMC0-403ED serves as the current production equivalent within the XMC0 series, providing the same functionality with enhanced current capacity.
