Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0873400623 is determined by the following critical parameters:

• Connector Configuration: 6-position receptacle with 2 rows
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting Technology: Surface mount with solder termination
• Mechanical Interface: Push-pull fastening with board guide feature
• Contact Gender: Female socket contacts
• Compliance: ROHS3 compliance and MSL 1 rating

The Harwin M22-6360346 meets these core mechanical and electrical compatibility criteria, enabling substitution in applications where the connector footprint and mating interface are primary selection factors.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0873400623 and Harwin M22-6360346 are active products with ROHS3 compliance and MSL 1 ratings, supporting long-term availability and environmental regulatory compliance.

The Molex 0873400623 operates across -55°C to 105°C with gold mating contacts and 1A current rating. The Harwin M22-6360346 operates across -40°C to 105°C with tin mating contacts and 2A current rating. Selection between these parts depends on specific application requirements regarding operating temperature range, contact finish material, and current capacity.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M22-6360346 directly replace the Molex 0873400623?

A: Direct replacement is possible when the application accommodates the mechanical footprint and mating interface. Both connectors share identical pitch (0.079"), position count (6), row configuration (2 rows), and mounting technology (surface mount solder). Verify that the application does not require the specific operating temperature range below -40°C or the gold contact finish of the original part.

Q: What is the primary difference between these connectors?

A: The main differences are contact finish material (gold versus tin), current rating (1A versus 2A), and operating temperature range (-55°C to 105°C versus -40°C to 105°C). The Harwin part supports higher current capacity and features tin plating, while the Molex part provides extended low-temperature operation and gold plating.

Q: Are both connectors suitable for automotive applications?

A: The Molex 0873400623 is specified for automotive applications. The Harwin M22-6360346 is specified for general purpose, industrial, and telecommunications applications. Application suitability should be confirmed against specific automotive qualification requirements.

Q: Do these connectors have the same package and handling requirements?

A: Both connectors are supplied in tube packaging with MSL 1 (unlimited) moisture sensitivity rating, indicating no special moisture control is required during storage or handling.
