3M 3428-5403 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3428-5403 is a through-hole, right-angle rectangular connector header with 20 positions at 2.54mm pitch, designed for board-to-board or cable interconnection applications. This connector features shrouded 4-wall construction with male pin contacts and solder termination. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. TE Connectivity AMP-Latch series connectors provide direct functional equivalents with active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3M 3428-5403 is determined by strict equivalence in the following critical parameters:

• Connector type: Header
• Contact type: Male pin
• Number of positions and rows: 20 positions, 2 rows
• Mating pitch: 0.100" (2.54mm)
• Row spacing: 0.100" (2.54mm)
• Mounting configuration: Through hole, right angle
• Shrouding: Shrouded 4-wall construction
• Termination method: Solder
• Contact mating length: 0.240" (6.10mm)
• Contact shape: Square
• Mating contact finish: Gold
• Current rating: 1A per contact
• Flammability rating: UL94 V-0

All four substitute parts—TE Connectivity 102322-4, 2-5499141-4, 499141-4, and 5102322-4—meet these core electrical and mechanical requirements. Variations exist in contact post length, post finish composition, insulation height, compliance certifications, and packaging format, which determine suitability for specific applications and regulatory environments.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select TE Connectivity 2-5499141-4 or 5102322-4. Both parts carry ROHS3 Compliant certification and REACH Unaffected status, meeting modern environmental and regulatory requirements. The 2-5499141-4 features a shorter contact post length (0.110" vs. 0.155") and blue insulation, while the 5102322-4 maintains the original post length with black insulation and tin post finish.

For RoHS Non-Compliant or Legacy Systems: TE Connectivity 102322-4 or 499141-4 are suitable alternatives. Both maintain RoHS non-compliant status consistent with the original 3M 3428-5403. The 102322-4 preserves the original contact post length (0.155"), while 499141-4 uses a shorter post (0.110") with tin-lead finish.

For Packaging Considerations: TE 2-5499141-4 and 5102322-4 are supplied in tray packaging with the highest inventory availability (1876 and 1217 units respectively). TE 499141-4 is available in bulk packaging. Select based on procurement and assembly workflow requirements.

For Temperature Range Extension: All TE Connectivity substitutes extend the lower operating temperature limit to -65°C compared to the original -55°C specification, providing improved performance in cold environments.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity AMP-Latch connectors directly replace the 3M 3428-5403 in existing designs?

A: Yes, all four TE Connectivity substitutes maintain electrical and mechanical compatibility with the 3M 3428-5403. Core parameters including connector type, contact configuration, pitch, mounting style, and shrouding are identical. Minor variations in contact post length (0.110" vs. 0.155"), insulation height (0.315" vs. 0.340"), and contact material (brass vs. copper alloy) do not affect functional compatibility in standard applications.

Q: What is the difference between the contact post lengths in the substitute parts?

A: The 3M 3428-5403, TE 102322-4, and TE 5102322-4 feature 0.155" (3.94mm) contact post length, while TE 2-5499141-4 and TE 499141-4 feature 0.110" (2.79mm) post length. Post length affects solder joint formation and PCB hole engagement. Verify PCB design specifications to confirm compatibility with the selected post length.

Q: Are there RoHS compliance differences between the substitute options?

A: Yes. TE 2-5499141-4 and TE 5102322-4 are ROHS3 Compliant with REACH Unaffected status, suitable for applications requiring modern environmental compliance. TE 102322-4 and TE 499141-4 are RoHS non-compliant, matching the original 3M part status. Select based on end-product regulatory requirements.

Q: What is the significance of the insulation color difference?

A: The TE 2-5499141-4 features blue insulation while all other parts use black. Insulation color does not affect electrical or mechanical function and is typically a manufacturing or series designation. Select based on design documentation or assembly identification requirements.

Q: How do the contact finish specifications compare?

A: All parts maintain 30.0µin (0.76µm) gold or gold-palladium mating contact finish. Post finish varies: the original uses tin-lead, while TE substitutes use either tin-lead (102322-4, 499141-4) or tin (2-5499141-4, 5102322-4). Post finish does not affect mating performance and relates to solderability and environmental resistance during assembly.

Q: Which substitute offers the best inventory availability?

A: TE 2-5499141-4 provides the highest inventory with 1876 units in stock, followed by TE 5102322-4 with 1217 units. Both are supplied in tray packaging suitable for automated assembly. TE 499141-4 offers 841 units in bulk packaging.
