Substitute Part Grouping Explanation

Substitution of the M20-9700545 is based on strict equivalence of the following critical parameters:

Connector type, contact type, and gender (Header, Male Pin)
Pitch spacing (0.100" / 2.54mm mating pitch)
Position count and row configuration (10 positions, 2 rows)
Row spacing (0.100" / 2.54mm)
Mounting style (Through Hole, Right Angle)
Termination method (Solder)
Current and temperature ratings (3A per contact, -40°C to 105°C)
Compliance certifications (UL94 V-0, ROHS3, REACH Unaffected)

The M20-9950545 meets all these criteria and is classified as an active product within the same M20 series, making it a direct functional equivalent for the obsolete M20-9700545.

Engineering Selection Recommendations

The M20-9950545 is the direct substitute for the obsolete M20-9700545. Both connectors are manufactured by Harwin Inc. within the same M20 series and share identical electrical and mechanical specifications with the exception of contact length at mating (0.276" versus 0.240"). This minor dimensional difference does not affect functional compatibility for standard board-to-board or cable applications.

The M20-9950545 holds active product status, ensuring ongoing availability and manufacturer support. Both parts maintain equivalent compliance certifications: UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status. Current rating (3A per contact) and operating temperature range (-40°C to 105°C) are identical.

Selection of the M20-9950545 eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs utilizing the M20-9700545.

Frequently Asked Questions (FAQ)

Q: Can the M20-9950545 directly replace the M20-9700545 in existing designs?

A: Yes. Both connectors share identical pitch spacing (0.100" / 2.54mm), position count (10 positions in 2 rows), mounting type (through-hole right-angle), termination method (solder), current rating (3A per contact), and operating temperature range (-40°C to 105°C). The M20-9950545 is a direct functional equivalent.

Q: What is the difference in contact length between these two parts?

A: The M20-9700545 has a mating contact length of 0.276" (7.00mm), while the M20-9950545 has a mating contact length of 0.240" (6.10mm). Both maintain identical post length (0.118" / 3.00mm) and insulation height (0.200" / 5.08mm). This dimensional variation does not affect standard board-to-board or cable interconnect applications.

Q: Are there packaging differences between these parts?

A: The M20-9700545 packaging is not specified in the available data. The M20-9950545 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
