Substitute Part Grouping Explanation

The M80-7490442 has been superseded by the M80-8820442, a manufacturer-recommended substitute from Harwin Inc. This substitution is based on the following alignment criteria:

The substitute part maintains the same manufacturer (Harwin Inc.) and product category (Rectangular Connectors). Both components are designed for board-to-board or cable connectivity applications. The M80-8820442 represents an active product with current manufacturing support, addressing the obsolescence status of the original part. The substitute provides defined electrical and mechanical specifications including connector type (Header), contact configuration (Male Pin), pitch specification (0.079" / 2.00mm), and position count (4 positions, single row).

Key parameters determining substitution validity:

• Manufacturer consistency (Harwin Inc.)
• Connector category and type alignment
• Contact pitch and position compatibility
• Mounting methodology (Through Hole)
• Environmental compliance and certifications
