Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 146280-3 is based on the following critical parameters that must align across all candidate parts:

Mandatory Matching Parameters:

• Number of Positions: 3
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 1
• Mounting Type: Through Hole
• Contact Material: Copper Alloy
• Contact Finish - Mating: Gold
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts identified are from the Mill-Max Manufacturing Corp. 821 series. These parts function as spring piston connectors that maintain electrical and mechanical compatibility with the original specification through matching pitch, position count, row configuration, and through-hole mounting methodology. All substitute parts are classified as active products with current manufacturing status and RoHS3 compliance, addressing the obsolescence of the original part.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 146280-3 is classified as obsolete, making transition to an active substitute part necessary for new procurement and design continuity. All three Mill-Max 821 series alternatives (821-22-003-10-002101, 821-22-003-10-003101, and 821-22-003-10-004101) satisfy the core electrical and mechanical requirements through matching pitch, position count, and through-hole mounting configuration.

The Mill-Max substitutes provide additional compliance advantages over the original part. All three alternatives are RoHS3 compliant, whereas the original 146280-3 is RoHS non-compliant. Additionally, all substitutes are REACH unaffected, compared to the original part's REACH affected status. These compliance improvements align with current regulatory requirements for electronic component procurement.

The contact finish thickness on the Mill-Max parts (20.0µin / 0.51µm) exceeds that of the original part (15.0µin / 0.38µm), providing enhanced durability and contact reliability. All parts maintain identical moisture sensitivity levels and operate within the same environmental temperature range.

Selection among the three Mill-Max alternatives should be based on specific application requirements and connector interface specifications, as all three parts are functionally equivalent for the core substitution criteria.

Frequently Asked Questions (FAQ)

Q: Why is the TE Connectivity 146280-3 being replaced?

A: The TE Connectivity 146280-3 is classified as obsolete. Active manufacturing has ceased, making it necessary to identify current production alternatives that maintain electrical and mechanical compatibility for ongoing applications.

Q: What are the critical compatibility parameters for substitution?

A: The substitute parts must maintain the following specifications: 3-position configuration, 0.100" (2.54mm) pitch spacing, single-row layout, through-hole mounting, copper alloy contact material, and gold mating surface finish. All identified Mill-Max alternatives meet these requirements.

Q: Are the Mill-Max 821 series connectors mechanically compatible with the original part?

A: Yes. The Mill-Max 821 series maintains identical pitch spacing (0.100" / 2.54mm), position count (3), row configuration (1), and through-hole mounting methodology. These parameters ensure mechanical compatibility with existing PCB layouts and mating connectors designed for the original part.

Q: What is the difference between the three Mill-Max substitute part numbers?

A: The three Mill-Max part numbers (821-22-003-10-002101, 821-22-003-10-003101, and 821-22-003-10-004101) are functionally equivalent for the core substitution criteria. Differentiation among these parts relates to specific connector interface configurations and application-specific requirements not detailed in the provided parameters.

Q: Do the substitute parts offer compliance improvements?

A: Yes. All three Mill-Max alternatives are RoHS3 compliant and REACH unaffected, whereas the original TE Connectivity part is RoHS non-compliant and REACH affected. These improvements align with current regulatory standards for electronic component procurement.

Q: Is there a difference in contact finish quality between the original and substitute parts?

A: The Mill-Max substitutes feature a contact finish thickness of 20.0µin (0.51µm) compared to the original part's 15.0µin (0.38µm). This increased thickness provides enhanced durability and contact reliability while maintaining gold mating surface specifications.

Q: Are all three Mill-Max alternatives currently in stock?

A: Yes. All three Mill-Max alternatives are available in active inventory: 821-22-003-10-002101 (1988 pcs), 821-22-003-10-003101 (1583 pcs), and 821-22-003-10-004101 (1256 pcs).
