Substitute Part Grouping Explanation

Substitution of the M20-9700546 is determined by the following critical parameters that must remain constant:

Connector type: Header, cuttable configuration
Contact type: Male pin
Number of positions and rows: 10 positions in 2 rows
Pitch spacing: 0.100" (2.54mm) mating pitch and row spacing
Mounting style: Through hole, right angle
Termination method: Solder
Current rating: 3A per contact
Operating temperature range: -40°C ~ 105°C
Material flammability: UL94 V-0
RoHS compliance: ROHS3 Compliant

The M20-9950545 qualifies as a direct substitute based on these parameters. While minor variations exist in contact finish and mating contact length, these differences do not affect functional compatibility for standard applications within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

The M20-9950545 is the manufacturer-recommended substitute for the obsolete M20-9700546. Both components maintain identical electrical and mechanical specifications across all critical parameters, including pitch, position count, current rating, and operating temperature range. Both parts satisfy ROHS3 compliance and UL94 V-0 flammability requirements.

The primary distinction is product status: M20-9700546 is obsolete, while M20-9950545 is active and maintains current manufacturing support. The M20-9950545 features gold contact finish on mating surfaces compared to tin finish on the original part, which provides enhanced corrosion resistance and contact reliability. The mating contact length difference of 0.036" (0.90mm) does not affect functional compatibility within standard application parameters.

For new designs or ongoing production requiring this connector type, M20-9950545 is the appropriate selection to ensure long-term component availability and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can M20-9950545 directly replace M20-9700546 in existing designs?

A: Yes. Both connectors share identical pitch spacing (0.100"), position count (10 positions, 2 rows), mounting style (through-hole right angle), and electrical ratings (3A per contact, -40°C ~ 105°C). The gold contact finish of M20-9950545 provides equivalent or superior performance compared to the tin finish of the original part.

Q: What is the significance of the contact finish difference?

A: M20-9700546 uses tin contact finish, while M20-9950545 uses gold contact finish. Gold provides superior corrosion resistance and contact reliability, particularly in environments with moisture or thermal cycling. This represents an improvement over the original specification.

Q: Why is M20-9700546 listed as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production. M20-9950545 is the active equivalent maintained by Harwin Inc. for ongoing procurement and design support.

Q: Are there packaging differences between these parts?

A: M20-9700546 packaging information is not specified in the available data. M20-9950545 is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: Do both parts meet the same compliance standards?

A: Yes. Both M20-9700546 and M20-9950545 are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and classified as Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the mating contact length difference, and does it affect compatibility?

A: M20-9700546 has 0.276" (7.00mm) mating contact length; M20-9950545 has 0.240" (6.10mm). This 0.036" (0.90mm) difference does not affect mating compatibility or electrical performance in standard applications.
