Amphenol ICC 66925-010 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66925-010 is a 20-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole, right-angle PCB mounting with solder termination. This connector is part of the Dubox™ series and features gold-plated mating contacts with tin-plated posts. The product is currently active in production with 649 units in stock.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative compliance certifications are required, or when design specifications allow for compatible connector variants that meet the same electrical and mechanical interface requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66925-010 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Must be receptacle with female socket contacts
• Position Count & Pitch: Must maintain 20 positions at 0.100" (2.54mm) mating pitch with 2 rows at 0.100" (2.54mm) row spacing
• Mounting & Termination: Must support through-hole, right-angle PCB mounting with solder termination
• Fastening Mechanism: Must use push-pull fastening type
• Insulation Material & Flammability: Must meet UL94 V-0 flammability rating

The two substitute parts listed—TE Connectivity AMP Connectors 5535512-2 and Samtec Inc. BCS-110-T-D-HE—satisfy all critical mechanical and electrical interface requirements. Variations in contact finish materials, insulation polymers, and post contact finishes do not affect interchangeability when mating with standard 0.100" pitch headers.

Parameter Comparison

Engineering Selection Recommendations

66925-010 (Amphenol ICC Dubox™)

• RoHS non-compliant; suitable for applications without RoHS requirements
• Gold mating contact finish provides enhanced corrosion resistance
• Polyamide (PA) nylon insulation material
• 649 units currently in stock

5535512-2 (TE Connectivity AMPMODU Mod II)

• RoHS Compliant; required for applications subject to RoHS directives
• Gold mating contact finish with higher post contact finish thickness (150.0µin vs. 100.0µin)
• Polyester glass-filled insulation material
• Operating temperature range: -55°C ~ 125°C
• Current rating: 2A per contact
• 2080 units currently in stock

BCS-110-T-D-HE (Samtec Tiger Claw™ BCS)

• ROHS3 Compliant; meets current RoHS requirements
• Tin mating contact finish; suitable for applications where gold plating is not required
• Liquid Crystal Polymer (LCP) glass-filled insulation material
• Operating temperature range: -55°C ~ 125°C
• Current rating: 4.6A per contact
• Voltage rating: 475VAC
• 832 units currently in stock

Selection between these parts depends on compliance requirements, contact finish specifications, and current/voltage rating demands of the application.

Frequently Asked Questions (FAQ)

Q: Can the 5535512-2 directly replace the 66925-010 in existing designs? A: Yes. Both connectors maintain identical mating pitch (0.100"), position count (20), row configuration (2 rows at 0.100" spacing), mounting type (through-hole right-angle), and fastening mechanism (push-pull). The primary difference is RoHS compliance status and insulation material composition, which do not affect mechanical or electrical interchangeability.

Q: What is the difference between gold and tin contact finishes? A: The 66925-010 and 5535512-2 feature gold-plated mating contacts, while the BCS-110-T-D-HE uses tin plating. Gold provides superior corrosion resistance and lower contact resistance over extended storage periods. Tin plating is suitable for applications with regular mating cycles and shorter storage intervals. Both finishes are compatible with standard 0.100" pitch header pins.

Q: Are there dimensional compatibility concerns between these three connectors? A: Insulation heights vary slightly: 66925-010 (0.240"), 5535512-2 (0.238"), and BCS-110-T-D-HE (0.210"). Contact post lengths also differ: 66925-010 and 5535512-2 (0.115"), BCS-110-T-D-HE (0.125"). These variations are within standard PCB design tolerances and do not prevent interchangeability on standard 0.100" pitch through-hole layouts.

Q: Which substitute part should be selected for RoHS-compliant applications? A: Both 5535512-2 (RoHS Compliant) and BCS-110-T-D-HE (ROHS3 Compliant) meet RoHS requirements. The 66925-010 is RoHS non-compliant and cannot be used in applications requiring RoHS certification.

Q: What are the current and voltage ratings for each connector? A: The 66925-010 does not specify current or voltage ratings in available documentation. The 5535512-2 is rated for 2A per contact. The BCS-110-T-D-HE is rated for 4.6A per contact at 475VAC. Application-specific current and voltage requirements should determine part selection.

Q: Are all three connectors available in the same packaging format? A: Yes. All three connectors are supplied in tube packaging, suitable for standard component handling and automated assembly processes.
