Amphenol ICC 65863-021 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 65863-021 is a shrouded vertical header connector with 20 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This through-hole connector is designed for board-to-cable/wire applications with solder termination and push-pull fastening. The part is currently active in production with 609 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 65863-021 is determined by strict equivalence in the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count (20 positions)
• Row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact shape (Square)
• Flammability compliance (UL94 V-0)

The TE Connectivity AMP Connectors 102156-4 meets all these critical parameters and qualifies as a direct substitute. Variations in contact length, insulation height, contact finish composition, and operating temperature specifications do not prevent functional substitution when these parameters are within acceptable design tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 65863-021 and TE Connectivity 102156-4 are active production parts with identical compliance certifications (UL94 V-0, MSL 1). Both maintain RoHS non-compliant status and carry the same ECCN and HTSUS classifications. The TE Connectivity 102156-4 provides additional operational specifications including operating temperature range (-65°C ~ 105°C), current rating (1A per contact), and voltage rating (250VAC), which may be advantageous for applications requiring defined performance boundaries. Selection between these parts should be based on availability, lead time, and specific application requirements within the stated electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 102156-4 be used as a direct replacement for the Amphenol ICC 65863-021?

A: Yes. Both connectors share identical critical parameters: 20-position, 2-row configuration at 0.100" pitch, through-hole solder termination, push-pull fastening, and 4-wall shrouding. Functional compatibility is established through these equivalent specifications.

Q: What are the differences in contact dimensions between these parts?

A: The TE Connectivity 102156-4 has slightly longer mating contacts (0.240" vs. 0.230") and post contacts (0.155" vs. 0.150"). The Amphenol ICC part has greater insulation height (0.640" vs. 0.549"). These dimensional variations do not affect electrical or mechanical compatibility for standard board-to-cable applications.

Q: Are there compliance or certification differences?

A: Both parts carry identical flammability ratings (UL94 V-0), moisture sensitivity levels (MSL 1), and RoHS non-compliant status. Both are classified under the same ECCN and HTSUS codes.

Q: Does the TE Connectivity part include additional features?

A: The TE Connectivity 102156-4 includes a mounting flange feature not specified for the Amphenol ICC part. Both include keying slots. The TE part provides defined operating temperature (-65°C ~ 105°C), current (1A per contact), and voltage (250VAC) specifications.

Q: What packaging format is used for both parts?

A: Both the Amphenol ICC 65863-021 and TE Connectivity 102156-4 are supplied in tray packaging.
