Substitute Part Grouping Explanation

Substitution of the 3M 960258-6202-AR is determined by the following critical parameters that must remain constant:

Connector type: Receptacle
Number of positions: 58
Pitch and row spacing: 0.100" (2.54mm)
Mounting type: Through hole with solder termination
Fastening mechanism: Push-pull
Contact type: Female socket
Board-to-board style

Engineering Selection Recommendations

All Mill-Max 803 series substitutes maintain active product status, ensuring long-term availability and supply chain continuity. The 803-41-058-10-001000, 803-43-058-10-001000, 803-91-058-10-001000, and 803-93-058-10-001000 variants are ROHS3 compliant, suitable for applications requiring regulatory compliance with current environmental standards. The 803-99-058-10-001000 and 803-99-058-10-004000 variants are RoHS non-compliant due to tin-lead post finish composition.

For applications operating within the original -25°C to 105°C range, all substitutes provide expanded operating temperature capability (-55°C to 125°C), offering enhanced thermal margin. The substitute parts deliver higher current ratings (4.5A versus 2A), providing increased electrical capacity within the same form factor.

Selection between gold-plated mating contact variants (803-41, 803-43, 803-91, 803-93) and tin-lead mating contact variants (803-99) depends on application requirements and environmental exposure. Contact finish thickness specifications vary across the substitute group; refer to specific application requirements for contact durability and wear resistance criteria.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 803 series connectors directly replace the 3M 960258-6202-AR in existing designs?

A: Yes. All substitute parts maintain identical mechanical pitch (0.100"), row spacing (0.100"), number of positions (58), mounting type (through hole), and fastening mechanism (push-pull). PCB footprints are compatible. Insulation height variations (0.272" to 0.280") fall within acceptable tolerance ranges for standard board-to-board applications.

Q: What is the difference between the 803-41, 803-43, 803-91, and 803-93 variants?

A: These variants differ in contact finish specifications. The 803-41 and 803-91 feature 10.0µin (0.25µm) gold mating contact finish, while 803-43 and 803-93 feature 30.0µin (0.76µm) gold mating contact finish. The 803-91 and 803-93 use tin-lead post finish, whereas 803-41 and 803-43 use tin post finish. All four are ROHS3 compliant.

Q: What distinguishes the 803-99 series from other substitutes?

A: The 803-99 series features tin-lead mating contact finish (100.0µin / 2.54µm) instead of gold. Both 803-99-058-10-001000 and 803-99-058-10-004000 are RoHS non-compliant. The 004000 variant has reduced insulation height (0.272" versus 0.276").

Q: Are there operating temperature considerations when substituting?

A: The original 3M part operates -25°C to 105°C. All Mill-Max substitutes operate -55°C to 125°C, providing expanded thermal range. Applications limited to the original temperature window face no constraints; applications requiring extended temperature operation benefit from the substitute's enhanced capability.

Q: How do current ratings affect part selection?

A: The original 3M part is rated 2A; all Mill-Max substitutes are rated 4.5A. For applications requiring 2A or less, all substitutes are suitable. Applications exceeding 2A current demand require the Mill-Max substitutes to meet electrical requirements.

Q: What packaging format is available for the substitute parts?

A: All Mill-Max 803 series substitutes are supplied in bulk packaging, suitable for production assembly and component procurement workflows.
