Amphenol ICC 65823-019 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 65823-019 is a through-hole, right-angle rectangular connector header with 20 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and production continuity. The connector features shrouded 4-wall construction with push-pull fastening, gold-plated circular contacts, and phosphor bronze alloy contact material suitable for board-to-cable/wire applications.

Substitute Part Grouping Explanation

Substitution eligibility for the 65823-019 is determined by strict alignment with the following core parameters: 20-position configuration, 2-row arrangement, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, through-hole right-angle mounting, shrouded construction, push-pull fastening, solder termination, and male pin contact type. All identified substitute parts maintain these electrical and mechanical specifications.

The substitute parts are grouped into two categories:

Direct Manufacturer Equivalent: 65823-019LF is the same part from Amphenol ICC with identical electrical and mechanical parameters, differentiated only by packaging (bulk) and active product status with RoHS compliance.

Cross-Manufacturer Alternatives: Parts from TE Connectivity (102160-4), CW Industries (CWN-300-20-0021), and 3M (N3428-1002RB, N3428-1003RB) provide functional equivalence while introducing variations in contact geometry, material composition, shrouding configuration, and performance ratings that remain within acceptable substitution parameters.

Engineering Selection Recommendations

65823-019LF is the primary substitute for the obsolete 65823-019. Both parts are from Amphenol ICC with identical electrical and mechanical specifications. The 65823-019LF offers the advantage of active product status and RoHS compliance, making it suitable for new designs and applications with regulatory requirements.

102160-4 (TE Connectivity AMP-Latch series) provides cross-manufacturer equivalence with active product status. This part introduces square contact geometry and brass contact material instead of circular phosphor bronze contacts. It specifies operating temperature range (-65°C ~ 105°C) and voltage rating (250VAC) not provided for the original part. The 3-wall shrouding differs from the original 4-wall design.

CWN-300-20-0021 (CW Industries CWN series) maintains circular contact geometry and phosphor bronze material consistent with the original design. This part offers the widest operating temperature range (-55°C ~ 125°C) and ROHS3 compliance. Contact post length is shorter (0.090") compared to the original (0.105").

N3428-1002RB and N3428-1003RB (3M 3000 series) both provide ROHS3 compliance and active product status. These parts feature square contacts and copper alloy material. The primary distinction between them is contact post length: N3428-1002RB has 0.112" posts while N3428-1003RB has 0.155" posts, accommodating different PCB thicknesses and assembly requirements. Both specify 1.75A current rating and -55°C ~ 105°C operating temperature.

For applications requiring RoHS compliance, 65823-019LF, CWN-300-20-0021, N3428-1002RB, and N3428-1003RB are suitable. For legacy systems without RoHS requirements, 102160-4 remains available. Contact geometry and material variations require mechanical fit verification during integration.

Frequently Asked Questions (FAQ)

Q: Can I use 65823-019LF as a direct replacement for the obsolete 65823-019?

A: Yes. The 65823-019LF is manufactured by Amphenol ICC with identical electrical and mechanical parameters to the 65823-019. The only differences are packaging format (bulk) and product status (active). RoHS compliance of the 65823-019LF makes it preferable for new designs.

Q: What are the key differences between the 3M N3428-1002RB and N3428-1003RB?

A: Both parts are functionally equivalent with identical electrical specifications, shrouding, and contact configuration. The primary difference is contact post length: N3428-1002RB provides 0.112" posts while N3428-1003RB provides 0.155" posts. Selection depends on PCB thickness and assembly requirements.

Q: Why do some substitute parts have square contacts while the original has circular contacts?

A: Contact shape is a design variation between manufacturers. Square contacts (102160-4, N3428-1002RB, N3428-1003RB) and circular contacts (65823-019LF, CWN-300-20-0021) both meet the 20-position, 2-row, 2.54mm pitch specification. Mechanical fit verification is required during integration to confirm compatibility with mating connectors.

Q: Are all substitute parts RoHS compliant?

A: No. The 65823-019 and 102160-4 are RoHS non-compliant. The 65823-019LF is RoHS compliant. The CWN-300-20-0021, N3428-1002RB, and N3428-1003RB are ROHS3 compliant. Selection depends on regulatory requirements for your application.

Q: What is the difference between 4-wall and 3-wall shrouding?

A: The original 65823-019 features 4-wall shrouding for maximum EMI shielding and mechanical protection. The 3M 3000 series (N3428-1002RB, N3428-1003RB) uses 3-wall shrouding. Both configurations maintain push-pull fastening and keying slot functionality. Mechanical fit with mating connectors should be verified.

Q: Which substitute part has the highest current rating?

A: The 3M parts (N3428-1002RB and N3428-1003RB) specify 1.75A per contact, the highest among all listed substitutes. The TE Connectivity 102160-4 specifies 1A per contact. The CWN-300-20-0021 specifies 1A. The original 65823-019 does not specify a current rating.

Q: Can I mix substitute parts in the same assembly?

A: All listed parts maintain the same 20-position, 2-row, 2.54mm pitch configuration and are mechanically compatible for board mounting. However, contact geometry and material variations between manufacturers may affect mating connector compatibility. Verify mechanical fit with your specific mating connector before mixing parts.
