Engineering Selection Recommendations

For Standard Applications (Tin-Plated Contact Finish): Select Mill-Max 110-44-328-41-001000. This substitute maintains tin-plated mating contacts compatible with the original 3M 4828-3000-CP while providing active product status, ROHS3 compliance, and extended operating temperature range (-55°C to 125°C). The higher current rating (3 A versus 1 A) provides additional design margin without compromising compatibility.

For High-Reliability or Corrosion-Resistant Applications (Gold-Plated Contact Finish): Select Mill-Max 116-93-328-41-006000. This substitute provides gold-plated mating contacts for enhanced corrosion resistance and contact reliability. The elevated frame design and extended operating temperature range support demanding environments. Note that this part is RoHS non-compliant; verify compliance requirements for your application before selection.

Product Status Consideration: Both Mill-Max substitutes are active products with current manufacturing support, inventory availability, and established supply chains. The 3M 4828-3000-CP obsolete status makes these substitutes necessary for new production and ongoing system maintenance.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 110-44-328-41-001000 directly replace the 3M 4828-3000-CP? A: Yes. Both parts share identical mechanical dimensions (28-position DIP, 0.3" row spacing, 0.100" pitch), through-hole solder termination, and Moisture Sensitivity Level 1. The Mill-Max part provides enhanced electrical performance (3 A current rating versus 1 A) and extended operating temperature range (-55°C to 125°C versus -25°C to 85°C).

Q: What is the difference between the two Mill-Max substitutes? A: The primary difference is contact finish. Mill-Max 110-44-328-41-001000 features tin-plated mating contacts, while Mill-Max 116-93-328-41-006000 features gold-plated mating contacts. The gold-plated version includes an elevated frame design and is RoHS non-compliant. Both provide identical mechanical compatibility and 3 A current rating.

Q: Are there packaging differences between these parts? A: All three parts are supplied in tube packaging. Termination post lengths vary slightly: 3M 4828-3000-CP (not specified), Mill-Max 110-44-328-41-001000 (0.125" / 3.18mm), and Mill-Max 116-93-328-41-006000 (0.108" / 2.74mm). Verify PCB hole depth compatibility before selection.

Q: Do the substitute parts meet RoHS requirements? A: Mill-Max 110-44-328-41-001000 is ROHS3 compliant. Mill-Max 116-93-328-41-006000 is RoHS non-compliant. Verify regulatory requirements for your application and select accordingly.

Q: What contact materials are used in each part? A: 3M 4828-3000-CP uses phosphor bronze for both mating and post contacts. Mill-Max substitutes use beryllium copper for mating contacts and brass alloy for post contacts. These material changes provide improved electrical performance and contact reliability.
