The XT424012 meets all substitution criteria as a direct equivalent component within the TE Connectivity Potter & Brumfield Relays product line.

Parameter Comparison

Engineering Selection Recommendations

Both the XT484LB2 and XT424012 are classified as obsolete products and maintain ROHS3 compliance. The XT424012 provides complete electrical and mechanical equivalence for direct substitution in applications currently utilizing the XT484LB2.

The primary distinction between these parts is the coil insulation specification. The XT484LB2 does not specify coil insulation classification, while the XT424012 designates Class F coil insulation. The XT424012 also differs in moisture sensitivity level designation (Not Applicable versus 1 - Unlimited) and REACH status (REACH Unaffected versus Vendor Undefined).

For applications requiring continued operation of XT484LB2-based systems, the XT424012 serves as a direct functional replacement. Both components share identical electrical performance characteristics, socketable mounting configuration, and plug-in termination style.

Frequently Asked Questions (FAQ)

Q: Can the XT424012 directly replace the XT484LB2 in existing applications?

A: Yes. The XT424012 provides complete electrical and mechanical equivalence. All critical parameters including coil voltage, contact form, current rating, switching voltage, timing characteristics, and operating temperature range are identical. Both components utilize socketable mounting with plug-in termination, enabling direct socket replacement.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching coil voltage (12VDC), contact form (DPDT), contact current rating (8A), switching voltage (400VAC maximum), coil current (33.3 mA), coil resistance (360 Ohms), and timing specifications (9 ms operate, 6 ms release). Both parts meet these criteria.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant and carry EAR99 ECCN classification. The XT424012 specifies Class F coil insulation and REACH Unaffected status, while the XT484LB2 does not provide these specifications. These differences do not affect functional substitution capability.

Q: What is the significance of the socketable mounting configuration?

A: Socketable mounting enables both the XT484LB2 and XT424012 to be installed into standardized relay sockets without soldering. This configuration, combined with plug-in termination, allows for tool-free component replacement and system maintenance.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these components are no longer in active production. However, both parts remain available through existing inventory channels. The XT484LB2 has 806 pieces in stock, while the XT424012 has 893 pieces available.
