Amphenol ICC 66527-025 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66527-025 is a 50-position receptacle connector from the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This through-hole, right-angle mounted connector features gold-plated mating contacts and is rated for operating temperatures from -65°C to 125°C. The part is currently active in production with 1103 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 66527-025 is determined by strict alignment of critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Primary Matching Parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 50
• Pitch spacing: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing: 0.100" (2.54mm)
• Mounting configuration: Through hole, right angle
• Mating contact finish: Gold
• Mating contact finish thickness: 30.0µin (0.76µm)
• Contact length - post: 0.115" (2.92mm)
• Fastening type: Push-pull
• Contact shape: Square

The TE Connectivity AMP Connectors part number 5-534204-1 meets all primary matching parameters and qualifies as a manufacturer-recommended substitute. Minor variations in secondary parameters such as contact material composition (phosphor bronze vs. brass), post finish thickness, and insulation height tolerance do not affect functional interchangeability in board-to-board applications where the specified pitch, position count, and contact geometry are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 66527-025 and TE Connectivity 5-534204-1 are active production parts with identical product status. The Amphenol ICC part carries UL94 V-0 flammability certification and is RoHS non-compliant. The TE Connectivity substitute is RoHS3 compliant, which may be a determining factor for applications subject to RoHS regulations.

Selection between these parts should be based on:

1. Regulatory Compliance Requirements: If RoHS3 compliance is mandated, the TE Connectivity 5-534204-1 is the appropriate choice. If RoHS non-compliance is acceptable or required, the Amphenol ICC 66527-025 remains suitable.

2. Supply Chain Availability: Current inventory shows 1103 units of the Amphenol ICC part and 1578 units of the TE Connectivity part in stock, providing flexibility for procurement decisions.

3. Mechanical Fit: The insulation height difference of 0.002" (0.05mm) between parts is within typical PCB tolerance stackup and does not affect functional interchangeability in standard board-to-board applications.

4. Contact Material Composition: The Amphenol ICC part uses brass contacts while the TE Connectivity part uses phosphor bronze. Both materials with their respective plating systems provide equivalent electrical performance for the specified voltage and current applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-534204-1 be used as a direct replacement for the Amphenol ICC 66527-025?

A: Yes. Both connectors share identical pitch spacing (0.100"), position count (50), row configuration (2 rows), mounting style (through-hole right angle), and contact geometry (square, gold-plated mating surface). The connectors are mechanically and electrically interchangeable in board-to-board applications.

Q: What is the significance of the insulation height difference of 0.002" between the two parts?

A: The insulation height difference (0.240" vs. 0.238") is within standard manufacturing tolerances and does not affect PCB mounting or mating performance. This variation is typical across connector families and does not impact functional compatibility.

Q: Does the difference in contact material (brass vs. phosphor bronze) affect performance?

A: No. Both materials, when combined with their respective plating systems (tin post finish), provide equivalent electrical conductivity and contact resistance characteristics for the specified 1250V rating and board-to-board application environment.

Q: Why is RoHS compliance different between these two parts?

A: The Amphenol ICC 66527-025 predates RoHS3 requirements and is designated as non-compliant. The TE Connectivity 5-534204-1 is manufactured to RoHS3 standards. Selection depends on application regulatory requirements.

Q: Are there any termination differences I should be aware of?

A: The Amphenol ICC part specifies solder termination, while the TE Connectivity part specifies kinked pin solder termination. Both are solder-based termination methods suitable for through-hole PCB assembly. The kinked pin design in the TE Connectivity part provides additional mechanical retention during soldering.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard storage and handling practices apply without special desiccant or baking requirements.
