Engineering Selection Recommendations

All Mill-Max 801 series alternatives are active products with current manufacturing support, addressing the obsolescence of the 960128-6202-AR. Selection among substitute parts depends on specific application requirements:

Gold-Plated Mating Contact Options (801-41, 801-91, 801-93 series): These maintain gold contact finish compatibility with the original part. The 801-93-028-10-001000 offers ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), suitable for applications requiring modern regulatory alignment. The 801-41 and 801-91 series are RoHS non-compliant but provide alternative contact material specifications (Beryllium Copper vs. Copper Alloy).

Tin-Lead Mating Contact Options (801-99 series): These provide ROHS3 compliance with tin-lead contact finish. Multiple configurations address different insulation heights and contact post lengths. The 801-99-028-20-001000 offers right-angle mounting for applications requiring board-edge connector placement.

All substitute parts exceed the original 2A current rating at 4.5A and extend the operating temperature range to -55°C ~ 125°C, providing enhanced electrical performance and thermal capability.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 801 series connectors directly replace the 3M 960128-6202-AR?

A: Yes, all listed Mill-Max 801 series connectors maintain mechanical and electrical compatibility. The 28-position, 0.100" pitch through-hole solder interface is identical. Differences in contact finish (gold vs. tin-lead), insulation height, and contact post length must be evaluated against specific PCB layout and mating connector specifications.

Q: What is the primary difference between gold-plated and tin-lead contact finish options?

A: Contact finish affects corrosion resistance and solderability. Gold-plated contacts (801-41, 801-91, 801-93) provide superior corrosion resistance in high-humidity environments. Tin-lead contacts (801-99) offer standard solderability and are suitable for standard PCB assembly processes. Contact finish selection depends on environmental exposure and assembly requirements.

Q: Why do some substitute parts have different insulation heights?

A: Insulation height variations (0.165", 0.272", 0.276") accommodate different PCB stackup requirements and mating connector geometries. The original 960128-6202-AR specifies 0.280" insulation height. Substitute parts with 0.276" or 0.272" heights are mechanically compatible with standard 0.100" pitch connector systems. Verify mating connector specifications before selection.

Q: What does the right-angle mounting option (801-99-028-20-001000) provide?

A: The right-angle variant positions the connector perpendicular to the PCB surface, enabling board-edge mounting configurations. This differs from straight through-hole mounting of other alternatives. Select this variant only if PCB layout requires edge-mounted connector placement.

Q: Are all substitute parts RoHS compliant?

A: The 801-93-028-10-001000 and 801-99 series (001000, 002000, 004000, 012000, 020000) are ROHS3 compliant. The 801-41 and 801-91 series are RoHS non-compliant. Regulatory requirements determine compliance selection.

Q: How do current ratings compare between the original and substitute parts?

A: The original 960128-6202-AR is rated at 2A. All Mill-Max 801 series substitutes are rated at 4.5A, providing 2.25x current capacity. This enhanced rating supports higher-power applications without connector derating.
