Frequently Asked Questions (FAQ)

Q: Can the 1648030 be used as a direct replacement for the 1772939 in existing assemblies?

A: Yes. The 1648030 is functionally equivalent across all critical parameters: 10-position female insert, B10 size, terminal block screw termination, 600V rating, and identical operating temperature range. The higher current rating (13A vs. 10A) provides additional capacity without compromising compatibility.

Q: What is the difference between the HEAVYCON® KA-B and HEAVYCON® B10 series designations?

A: Both designations refer to 10-position B-size heavy duty connector inserts within the Phoenix Contact HEAVYCON® product family. The 1648030 represents the current active series designation.

Q: Are there any material differences between the two parts?

A: The 1772939 lists both polyamide/nylon and polycarbonate housing materials, while the 1648030 specifies polyamide/nylon. Both maintain UL94 V-0 flammability rating and identical contact material specifications (copper alloy with silver finish).

Q: Does the higher current rating of the 1648030 affect compatibility?

A: No. A higher current rating indicates increased capacity and does not create compatibility issues. The 1648030 can safely handle applications designed for the 1772939's 10A specification.

Q: What packaging options are available?

A: The 1772939 packaging is not specified in available data. The 1648030 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1772939 and 1648030 are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level.
