Equivalent & Substitute Parts for Amphenol ICC 66925-004

Part Overview

The Amphenol ICC 66925-004 is an 8-position receptacle connector from the Dubox™ series, designed for 0.100" (2.54mm) pitch through-hole, right-angle PCB mounting applications. This connector features gold-plated mating contacts and tin-plated posts with solder termination and push-pull fastening. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66925-004 is determined by strict alignment with the following core parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 8 positions at 0.100" (2.54mm) mating pitch
• Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Finish - Mating: Gold plating on mating surfaces

The substitute parts identified—Molex 0901522208 and Molex 0901522308—satisfy all critical electrical and mechanical parameters. Both are active-status rectangular connectors from the C-Grid III 90152 series with identical position counts, pitch specifications, mounting configurations, and fastening types. Both feature gold-plated mating contacts and push-pull fastening, ensuring mechanical and electrical compatibility with the original 66925-004 design.

Parameter Comparison

Engineering Selection Recommendations

Both Molex 0901522208 and Molex 0901522308 are qualified substitutes for the obsolete Amphenol ICC 66925-004 based on matching electrical and mechanical specifications. The primary distinction between the two Molex options is the mating contact finish thickness: 0901522208 provides 15.0µin (0.38µm) gold plating, while 0901522308 provides 30.0µin (0.76µm) gold plating, matching the original 66925-004 specification.

Both substitute parts carry active product status and ROHS3 compliance, providing regulatory advantage over the non-compliant original part. The Molex connectors specify operating temperature range (-55°C ~ 105°C), current rating (3A), and voltage rating (350V), parameters not documented for the original 66925-004. These ratings establish defined performance boundaries for system design.

Minor dimensional variations exist: the Molex substitutes feature slightly reduced insulation height (0.230" versus 0.240") and contact post length (0.114" versus 0.115"), differences within typical manufacturing tolerances that do not affect PCB mounting or mating compatibility. Contact material differs (phosphor bronze versus brass), with phosphor bronze offering enhanced spring characteristics and durability in the Molex design.

Selection between 0901522208 and 0901522308 should prioritize the 0901522308 variant when direct gold plating thickness equivalence to the original 66925-004 is required. The 0901522208 variant remains electrically and mechanically compatible but with reduced mating contact durability due to thinner gold plating.

Frequently Asked Questions (FAQ)

Q: Can Molex 0901522208 and 0901522308 be used interchangeably with the Amphenol ICC 66925-004?

A: Both Molex parts are mechanically and electrically compatible substitutes. They share identical position counts, pitch specifications, mounting configurations, and fastening mechanisms. The primary difference is mating contact gold plating thickness. For applications requiring exact specification matching, 0901522308 is preferred due to its 30.0µin gold plating thickness, identical to the original part.

Q: What are the key compatibility criteria for substituting the 66925-004?

A: Substitution requires matching on: 8-position receptacle configuration, 0.100" (2.54mm) mating pitch, 2-row layout with 0.100" row spacing, through-hole right-angle mounting, solder termination, push-pull fastening, and gold-plated mating contacts. Both Molex substitutes satisfy all these criteria.

Q: Does the difference in contact material (brass versus phosphor bronze) affect compatibility?

A: Contact material does not affect mechanical or electrical compatibility. Phosphor bronze in the Molex substitutes provides enhanced spring characteristics and contact durability compared to brass. This represents a design improvement rather than a compatibility limitation.

Q: Are there packaging differences between the original and substitute parts?

A: The original 66925-004 packaging is not specified in available documentation. Molex 0901522208 and 0901522308 are supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the significance of the RoHS3 compliance on the Molex substitutes?

A: Both Molex substitutes carry ROHS3 compliance, whereas the original 66925-004 is RoHS non-compliant. This provides regulatory advantage for new designs and systems subject to RoHS directives. For legacy system repairs, compliance status does not affect electrical or mechanical performance.

Q: How do the operating temperature and electrical ratings of the substitutes compare to the original?

A: The original 66925-004 does not specify operating temperature, current, or voltage ratings. The Molex substitutes specify -55°C ~ 105°C operating range, 3A current rating, and 350V voltage rating. These defined ratings establish performance boundaries and should be verified against your application requirements.

Q: What dimensional tolerances should be considered when substituting these connectors?

A: Insulation height differs by 0.010" (0.25mm) and contact post length by 0.001" (0.02mm) between the original and Molex substitutes. These variations fall within standard manufacturing tolerances and do not affect PCB mounting hole alignment or mating connector engagement.
