Inventory and Availability:

The original 5447650-3 is obsolete with 837 pieces in stock. The substitute M39012/59-3026 is active with 703 pieces in stock, providing ongoing procurement availability.

Frequently Asked Questions (FAQ)

Q: Can M39012/59-3026 directly replace 5447650-3 in existing designs?

A: Yes. Both parts share identical specifications for connector style, type, impedance, termination methods, mounting configuration, frequency rating, and dielectric material. The substitute maintains functional and mechanical compatibility.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active), manufacturer (TE Connectivity versus Amphenol SV Microwave), body material composition (brass with nickel finish versus stainless steel), center contact material (unspecified versus beryllium copper with gold plating), and included components (6 pieces versus 2 pieces). Cable group support differs slightly, with the substitute not explicitly listing RG-188A compatibility.

Q: Are there cable group compatibility concerns?

A: The original part supports RG-174, 188A, and 316 cable groups. The substitute supports RG-174 and 316 cable groups. Applications using RG-188A cable should confirm compatibility with the substitute part specifications.

Q: What is the operating temperature range for these connectors?

A: The original 5447650-3 does not specify an operating temperature range. The substitute M39012/59-3026 operates from -65°C to 165°C.

Q: Are both parts RoHS compliant?

A: Yes. The original 5447650-3 is RoHS Compliant. The substitute M39012/59-3026 is ROHS3 Compliant, representing current regulatory standards.

Q: What is the difference in packaging?

A: The original 5447650-3 packaging is not specified. The substitute M39012/59-3026 is supplied in bulk packaging.

Q: How many components are included with each part?

A: The original 5447650-3 includes 6 pieces: 1 connector, 1 contact, 1 ferrule, 1 gasket, 1 lockwasher, and 1 nut. The substitute M39012/59-3026 includes 2 pieces: 1 connector and 1 lockwasher.

Q: What is the maximum frequency rating for these connectors?

A: Both the original 5447650-3 and substitute M39012/59-3026 are rated for a maximum frequency of 12.4 GHz.

Q: Are there REACH compliance differences?

A: The original 5447650-3 has undefined REACH status. The substitute M39012/59-3026 is designated as REACH Affected. Organizations operating under REACH regulations should confirm applicability within their supply chain.
