Key Parameters

Substitute Part Grouping Explanation

Substitution of the M20-8770546R is determined by strict equivalence across the following critical parameters:

• Connector type classification (Header, Cuttable)
• Contact type and gender (Male Pin)
• Position count and row configuration (5 positions, 1 row)
• Mating pitch specification (0.100" / 2.54mm)
• Mounting technology (Surface Mount)
• Termination method (Solder)
• Current and temperature ratings (3A per Contact, -40°C ~ 105°C)
• Insulation material and flammability compliance (Polyamide PA6T, UL94 V-0)

The M20-8770546 qualifies as a direct substitute based on identical electrical and mechanical specifications across all provided parameters. The primary distinction is product status: M20-8770546R is obsolete, while M20-8770546 maintains active production status with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The M20-8770546 is the direct functional equivalent for applications currently specified with M20-8770546R. Selection of the active part is supported by:

• Identical electrical performance across all specified parameters
• Active production status ensuring long-term supply chain continuity
• ROHS3 compliance certification on the substitute part, meeting current regulatory requirements
• Substantially higher inventory availability (56895 units versus 1110 units)
• Identical mechanical and thermal specifications for direct PCB layout compatibility

For new designs or production transitions, M20-8770546 is the appropriate selection. For existing inventory management of M20-8770546R, the substitute part provides equivalent functionality without design modification.

Frequently Asked Questions (FAQ)

Q: Can M20-8770546 be used as a direct replacement for M20-8770546R in existing designs?

A: Yes. Both parts share identical specifications across connector type, contact configuration, pitch, mounting method, current rating, temperature range, and insulation properties. No circuit design or PCB layout modifications are required.

Q: What is the difference between M20-8770546R and M20-8770546?

A: The primary differences are product status (obsolete versus active) and regulatory compliance documentation. M20-8770546R is no longer in production. M20-8770546 is the active equivalent with ROHS3 certification and higher inventory availability.

Q: Are there packaging differences between these parts?

A: M20-8770546R packaging is not specified in available data. M20-8770546 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Does the substitute part meet current regulatory requirements?

A: M20-8770546 carries ROHS3 compliance certification. Both parts maintain REACH Unaffected status. Verify compliance requirements against your specific application and regional standards.

Q: What is the mating pitch, and does it affect substitution?

A: Both parts operate at 0.100" (2.54mm) mating pitch. This standard pitch is maintained across the M20 series, ensuring mechanical compatibility with existing mating connectors and PCB designs.

Q: Can these parts be cut to shorter lengths?

A: Both parts are classified as cuttable headers. Cutting procedures and resulting electrical performance are determined by application-specific requirements and should follow Harwin Inc. technical guidance.
