Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3007042 directly replace the 3003949 in existing installations?

A: Yes. Both parts share the same wire gauge range (12-26 AWG), voltage rating (300V UL), series designation (CLIPLINE UKK), and termination method (screw). The 3007042 is the manufacturer-recommended substitute for the obsolete 3003949.

Q: What is the primary difference between these two parts?

A: The 3003949 is a basic feed-through terminal block, while the 3007042 adds disconnect functionality with 4 positions and 2 levels. The 3007042 also provides additional electrical specifications including 26 A current rating at 400V IEC and enhanced material flammability rating (UL94 V-2).

Q: Are there any packaging differences between the main part and substitute?

A: The 3003949 packaging is not specified in available documentation. The 3007042 is supplied in bulk packaging, which is standard for terminal block components in production environments.

Q: Does the substitute part require any design modifications?

A: No design modifications are required for wire gauge or voltage specifications. The substitute maintains full compatibility with 12-26 AWG conductors and 300V UL applications. The additional disconnect and position features of the 3007042 provide enhanced functionality without compromising backward compatibility.

Q: What is the moisture sensitivity level of the substitute part?

A: The 3007042 has a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
