Substitute Part Grouping Explanation

Substitution of the M20-8770946P is determined by strict equivalence across the following critical parameters:

• Connector pitch: 0.100" (2.54mm)
• Number of positions: 9
• Number of rows: 1
• Mounting type: Surface Mount
• Connector type: Header, Cuttable
• Contact type: Male Pin
• Termination method: Solder
• Insulation material: Polyamide (PA6T), Nylon 6T
• Operating temperature range: -40°C ~ 105°C
• Current rating: 3A per Contact
• Material flammability: UL94 V-0
• Compliance: ROHS3 Compliant, REACH Unaffected

The M20-8770942 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status and contact finish specification.

Parameter Comparison

Engineering Selection Recommendations

The M20-8770942 is the direct substitute for the obsolete M20-8770946P. Both components are manufactured by Harwin Inc. within the M20 series and maintain identical electrical and mechanical specifications across all critical parameters.

The M20-8770942 is currently in Active product status with higher inventory availability (2383 Pcs), compared to the M20-8770946P which is Obsolete. Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

The contact finish on the mating surface differs between the two parts: the M20-8770946P features tin finish, while the M20-8770942 features gold finish. Both contact finishes are compatible with standard solder termination processes and maintain the same current rating of 3A per contact.

Frequently Asked Questions (FAQ)

Q: Can M20-8770942 be used as a direct replacement for M20-8770946P?

A: Yes. The M20-8770942 is a direct substitute. Both parts share identical connector pitch (0.100" / 2.54mm), position count (9), row configuration (1), mounting type (Surface Mount), termination method (Solder), and electrical ratings (3A per contact). The primary difference is product status and contact finish specification.

Q: What is the difference between tin and gold contact finishes?

A: The M20-8770946P uses tin finish on mating contacts, while the M20-8770942 uses gold finish. Both finishes are compatible with solder termination and maintain equivalent electrical performance for this application. Gold finish provides enhanced corrosion resistance in certain environmental conditions.

Q: Are there packaging differences between these parts?

A: The M20-8770946P is listed with unspecified packaging, while the M20-8770942 is supplied in Bulk packaging. Both parts are identical in form, fit, and function.

Q: Why is the M20-8770946P classified as Obsolete?

A: The M20-8770946P has been superseded by the M20-8770942 within Harwin Inc.'s product line. The M20-8770942 remains in Active status and is the recommended part for new designs and ongoing production.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the M20-8770946P and M20-8770942 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: What are the mated stacking heights?

A: Both parts support identical mated stacking heights: 11.63mm, 12.23mm, 12.63mm, and 18.13mm, providing flexibility for various board-to-board spacing requirements.
