Frequently Asked Questions (FAQ)

Q: Can M22-5320405 be used as a direct replacement for M22-5320446?

A: Yes. The M22-5320405 is the active equivalent from Harwin Inc. Both parts share identical pitch (2.00mm), position count (8), row configuration (2), mounting type (surface mount), and termination method (solder). The primary difference is contact finish (gold on M22-5320405 versus tin on M22-5320446). Both maintain UL94 V-0 flammability rating and ROHS3 compliance.

Q: What are the differences between the Harwin M22-5320405 and Molex 0877590851?

A: Both connectors match on pitch, position count, row spacing, and mounting type. Key differences include: (1) Contact length mating: M22-5320405 is 0.138" (4.60mm) while 0877590851 is 0.150" (3.81mm); (2) Connector type: M22-5320405 is cuttable header while 0877590851 is breakaway header; (3) Insulation material: M22-5320405 uses polyamide (PA6T) while 0877590851 uses thermoplastic; (4) Features: 0877590851 includes board guide.

Q: Are the Molex parts (0877590851 and 0877590894) interchangeable with each other?

A: Both Molex parts share identical pitch, position count, row spacing, and contact length mating (0.150"). The primary difference is insulation material composition and contact finish thickness: 0877590851 uses thermoplastic insulation while 0877590894 uses glass-filled polyamide. The 0877590894 includes pick-and-place optimization features.

Q: What is the significance of contact finish differences (tin versus gold)?

A: Contact finish affects corrosion resistance and solderability. Tin finish (M22-5320446) provides cost efficiency for standard applications. Gold finish (M22-5320405, 0877590851, 0877590894) offers enhanced corrosion resistance and is preferred for high-reliability applications. Both finishes are compatible with standard solder termination processes.

Q: Do all substitute parts maintain the same current rating?

A: The M22-5320405 specifies 1A per contact, matching the original M22-5320446. The Molex parts (0877590851 and 0877590894) do not specify current rating in the provided data. For applications requiring confirmed 1A per contact rating, the M22-5320405 is the recommended choice.

Q: What packaging options are available for these connectors?

A: M22-5320446 is supplied in bulk packaging. M22-5320405 is available in bulk packaging. 0877590851 is supplied in tube packaging. 0877590894 is available in bulk packaging. Packaging selection may affect procurement lead times and handling requirements.
