Amphenol ICC 65863-073 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 65863-073 is an active rectangular connector header designed for through-hole mounting applications. This vertical 26-position connector operates at 0.100" (2.54mm) pitch with shrouded 4-wall construction and latch lock/eject hook fastening. The part is currently in active production status with 1063 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the core specifications, enabling direct replacement in board-to-cable/wire connection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 65863-073 is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish substitution validity:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (26)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact shape (Square)
• Insulation material (Thermoplastic)
• Material flammability rating (UL94 V-0)

Identified Substitutes:

1. 65863-073LF (Amphenol ICC) - Direct manufacturer variant with identical core specifications. Differs in RoHS compliance status (RoHS Compliant vs. non-compliant) and insulation color (Black vs. Blue). Contact finish post differs (Tin vs. unspecified).

2. 499206-6 (TE Connectivity AMP Connectors) - Cross-manufacturer substitute from AMP-Latch series. Maintains all critical parameters with minor variations in contact length dimensions and includes operating temperature range (-65°C ~ 105°C) and current/voltage ratings (1A / 250VAC). Fastening type includes mounting flange addition.

Parameter Comparison

Engineering Selection Recommendations

65863-073 (Original Part): Suitable for applications where RoHS non-compliance is acceptable and blue insulation color is specified. Active production status ensures continued availability.

65863-073LF (Direct Manufacturer Substitute): Recommended for designs requiring RoHS compliance. Maintains identical core mechanical and electrical specifications with higher inventory availability (1790 units). Insulation color changes to black; contact post finish specified as tin. REACH affected status applies.

499206-6 (Cross-Manufacturer Substitute): Applicable for applications requiring operating temperature range (-65°C ~ 105°C) and rated current/voltage specifications (1A / 250VAC). Minor dimensional variations exist in contact lengths and insulation height. Mounting flange feature provides additional mechanical support. TE Connectivity AMP-Latch series compatibility should be verified for specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can 65863-073LF be used as a direct replacement for 65863-073?

A: Yes. Both parts maintain identical connector type, contact configuration, pitch, row spacing, mounting type, shrouding, fastening mechanism, and termination method. The primary differences are RoHS compliance status and insulation color. Verify that your application design does not specify blue insulation color as a requirement.

Q: What are the key differences between 65863-073 and 499206-6?

A: Both maintain the same 26-position, 2-row, 0.100" pitch header configuration with through-hole solder termination and 4-wall shrouding. The 499206-6 includes operating temperature range (-65°C ~ 105°C) and current/voltage ratings (1A / 250VAC). Contact length dimensions differ slightly (mating: 0.240" vs. 0.230"; post: 0.110" vs. 0.105"). Insulation height is reduced (0.549" vs. 0.640"). The 499206-6 includes a mounting flange feature.

Q: Are there packaging differences between these substitutes?

A: All three parts are supplied in tray packaging. Inventory quantities vary: 65863-073 (1063 units), 65863-073LF (1790 units), and 499206-6 (798 units).

Q: Which substitute should I select for a new design?

A: Selection depends on compliance requirements and environmental specifications. For RoHS-compliant designs, use 65863-073LF. For applications requiring temperature range and electrical ratings, use 499206-6. Verify that dimensional variations in contact length and insulation height do not conflict with mating connector specifications.

Q: Do all substitutes have the same contact finish specifications?

A: Mating contact finish thickness is identical (30.0µin / 0.76µm) across all three parts with gold or gold-based plating. Post contact finish differs: 65863-073 (not specified), 65863-073LF (tin), and 499206-6 (tin-lead).
