Equivalent & Substitute Parts for Amphenol ICC 66900-030

Part Overview

The Amphenol ICC 66900-030 is a 30-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination, designed for ribbon cable applications with 28-30 AWG wire gauge. This connector features gold-plated contacts, feed-through capability, and strain relief in a dual-row configuration with 0.100" pitch spacing.

The 66900-030 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 66900-030 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector geometry: 30 positions, dual-row configuration, 0.100" pitch and row spacing
• Termination method: IDC technology for ribbon cable
• Contact interface: Receptacle type with gold plating
• Wire compatibility: Support for ribbon cable with compatible AWG ranges
• Mounting configuration: Free hanging in-line orientation
• Functional features: Feed-through and strain relief capability

The substitute parts TE Connectivity AMP Connectors 1658620-7 and 1658623-7 meet these core requirements. Both are active-status receptacle connectors with 30 positions, matching pitch and row spacing, IDC termination for ribbon cable, and gold contact finish. Wire gauge compatibility spans 26-28 AWG, which overlaps with the original 28-30 AWG specification, allowing substitution for applications using 28 AWG ribbon cable.

Engineering Selection Recommendations

1658620-7 (TE Connectivity AMP-Latch Series)

This part is recommended for applications requiring active product status and RoHS compliance. The 1658620-7 is actively manufactured and maintains full RoHS compliance. Wire gauge compatibility with 26-28 AWG supports 28 AWG ribbon cable applications. Packaging in tube format is suitable for automated assembly processes. Contact type is forked, providing reliable IDC termination. This substitute is appropriate for new designs and production environments where compliance certifications are mandatory.

1658623-7 (TE Connectivity AMP-Latch Series)

This part is recommended for applications requiring ROHS3 compliance and maximum contact finish thickness. The 1658623-7 is actively manufactured with ROHS3 certification. Contact finish thickness of 30.0µin (0.76µm) matches the original 66900-030 specification, providing equivalent contact durability and wear characteristics. Wire gauge compatibility with 26-28 AWG supports 28 AWG ribbon cable applications. Bulk packaging format is suitable for high-volume production. Contact type is forked with gold or gold-palladium finish options.

Both substitutes are suitable for applications using 28 AWG ribbon cable. Selection between 1658620-7 and 1658623-7 depends on packaging requirements (tube versus bulk) and contact finish thickness preferences.

Frequently Asked Questions (FAQ)

Q: Can the 66900-030 be directly replaced with 1658620-7 or 1658623-7?

A: Yes, for applications using 28 AWG ribbon cable. Both substitute parts maintain the same 30-position, dual-row configuration with 0.100" pitch and row spacing. IDC termination method, receptacle type, and gold contact finish are identical. The wire gauge specification of 26-28 AWG on the substitutes overlaps with the original 28-30 AWG range at 28 AWG, ensuring compatibility for this common wire gauge.

Q: What is the difference between 1658620-7 and 1658623-7?

A: Both parts are TE Connectivity AMP-Latch series receptacles with identical electrical and mechanical specifications. Primary differences are packaging format (1658620-7 in tube, 1658623-7 in bulk), contact finish thickness (1658620-7 at 15.0µin, 1658623-7 at 30.0µin), and contact finish options (1658623-7 offers gold or gold-palladium). Selection depends on production volume, assembly automation requirements, and contact durability needs.

Q: Are there wire gauge compatibility concerns?

A: The original 66900-030 supports 28-30 AWG. Both substitutes support 26-28 AWG. For applications using 28 AWG ribbon cable, both substitutes are fully compatible. Applications requiring 29-30 AWG wire gauge cannot use these substitutes without design modification.

Q: What compliance certifications apply to the substitutes?

A: 1658620-7 is RoHS compliant. 1658623-7 is ROHS3 compliant. Both parts have MSL rating of 1 (Unlimited) and ECCN classification EAR99. The original 66900-030 is RoHS non-compliant. Substitution with either part upgrades compliance status for new production.

Q: Are strain relief features equivalent?

A: The original 66900-030 specifies both feed-through and strain relief features. Both substitutes specify feed-through capability. Strain relief feature availability on the substitutes is not explicitly provided in the specification data. Design validation is recommended if strain relief is a critical functional requirement.
