Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 532446-3 is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility Parameters:

• Connector type classification (Header, Male Pins)
• Position count (40 positions)
• Pitch specification (0.100" / 2.54mm)
• Row configuration (2 rows)
• Mounting methodology (Through Hole)
• Connector style designation (High Density)
• Contact finish material and thickness (Gold, 30.0µin)
• Operating temperature envelope (-65°C ~ 125°C)
• Flammability compliance (UL94 V-0)

The substitute part 532430-3 maintains equivalence across all these parameters. The primary distinction between the main part and its substitute is the termination method: the 532446-3 employs press-fit termination, while the 532430-3 utilizes solder termination. Both parts share identical connector geometry, electrical ratings, and environmental specifications.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 532430-3 serves as the direct substitute for the obsolete 532446-3. Selection of the 532430-3 is supported by the following engineering considerations:

Product Status: The 532446-3 is classified as obsolete, while the 532430-3 maintains active product status. Active status ensures continued availability, manufacturing support, and compliance with current regulatory requirements.

Regulatory Compliance: The 532430-3 carries REACH Affected designation, indicating compliance with current European Union chemical regulations. The 532446-3 lists REACH status as Vendor Undefined, which presents potential compliance uncertainty for new designs and procurement.

Electrical and Mechanical Equivalence: Both connectors maintain identical specifications across connector type, position count, pitch, row configuration, mounting methodology, contact finish, and operating temperature range. Both components satisfy UL94 V-0 flammability requirements and MSL 1 moisture sensitivity classification.

Termination Methodology: The substitution introduces a termination change from press-fit to solder. This difference requires PCB design modification to accommodate solder termination holes rather than press-fit receptacles. The connector geometry and mating interface remain unchanged.

Inventory and Procurement: The 532430-3 maintains significantly higher inventory availability (34,067 pieces) compared to the 532446-3 (1,014 pieces), supporting reliable procurement for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 532430-3 directly replace the 532446-3 without PCB modification?

A: The 532430-3 maintains identical connector geometry and mating interface specifications. However, the termination method differs: the 532446-3 uses press-fit termination while the 532430-3 requires solder termination. PCB footprint modification is necessary to accommodate the different termination hole specifications.

Q: Are the electrical performance characteristics identical between these two connectors?

A: Both connectors share identical electrical specifications including contact finish (gold, 30.0µin thickness), operating temperature range (-65°C to 125°C), and flammability rating (UL94 V-0). No electrical performance difference exists between the two parts.

Q: What is the significance of the REACH status difference?

A: The 532430-3 carries REACH Affected designation, confirming compliance with European Union chemical substance regulations. The 532446-3 lists REACH status as Vendor Undefined, which may present compliance documentation challenges for designs intended for European markets or subject to REACH requirements.

Q: Does the pitch specification remain constant across both connectors?

A: Both connectors maintain identical pitch specification of 0.100" (2.54mm) and 2-row configuration. Mating interface compatibility is preserved.

Q: What design considerations apply when transitioning from press-fit to solder termination?

A: Solder termination requires PCB design changes including modified hole sizing, plating specifications, and solder pad geometry compared to press-fit termination. Assembly process parameters differ between press-fit insertion and solder reflow operations.

Q: Is the 532430-3 suitable for applications requiring the same operating temperature range?

A: Both connectors operate across the identical temperature range of -65°C to 125°C. Temperature performance equivalence is maintained.

Q: What inventory considerations should influence the substitution decision?

A: The 532430-3 maintains substantially higher inventory availability (34,067 pieces) relative to the 532446-3 (1,014 pieces). The active product status of the 532430-3 supports long-term procurement reliability and production continuity.
