08CH-A-08-IDC Equivalent & Substitute Parts

Part Overview

The 08CH-A-08-IDC is an 8-position rectangular receptacle connector manufactured by Adam Tech, designed for wire-to-board crimp applications. This connector features IDC (Insulation Displacement Contact) termination with tin contact finish and supports 32-36 AWG discrete wire gauges. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain design continuity and procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08CH-A-08-IDC is determined by strict equivalence across the following critical parameters:

• Connector Series & Geometry: Both parts must belong to the 08CH series with identical 8-position, single-row configuration and 0.031" (0.80mm) pitch
• Termination Method: IDC cable termination is mandatory for compatibility with existing wire preparation and assembly processes
• Mounting Configuration: Free hanging (in-line) mounting type must be preserved
• Wire Gauge Compatibility: Support for 32-36 AWG discrete wire is required
• Electrical & Environmental Compliance: ROHS3 compliance and MSL 1 rating must be maintained

The 08CH-A-08-G-IDC qualifies as a direct substitute based on these parameters. The primary distinction is the contact finish material (gold versus tin), which represents an upgrade in corrosion resistance and contact reliability while maintaining full mechanical and electrical compatibility.

Engineering Selection Recommendations

The 08CH-A-08-G-IDC is the qualified substitute for the discontinued 08CH-A-08-IDC. Selection between these parts should be based on the following factors:

Product Availability: The 08CH-A-08-IDC is discontinued at DiGi Electronics with no active procurement status. The 08CH-A-08-G-IDC maintains active product status with current inventory availability.

Contact Finish Consideration: The gold flash finish on the 08CH-A-08-G-IDC provides enhanced contact durability and corrosion resistance compared to the tin finish of the original part. Both finishes maintain ROHS3 compliance and identical electrical performance within the specified wire gauge range.

Compliance & Certification: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory performance.

Packaging Format: The substitute is supplied in bag packaging rather than bulk. Procurement quantities should account for this packaging difference.

Frequently Asked Questions (FAQ)

Q: Can the 08CH-A-08-G-IDC be used as a direct replacement for the 08CH-A-08-IDC?

A: Yes. Both connectors share identical mechanical dimensions, pitch, position count, mounting configuration, and IDC termination method. The gold contact finish of the substitute provides equivalent or superior electrical performance compared to the tin finish.

Q: What is the primary difference between these two parts?

A: The contact finish material differs: the original part uses tin, while the substitute uses gold (flash thickness). This affects contact durability and corrosion resistance but does not impact mechanical compatibility or electrical specifications for the specified wire gauge range.

Q: Are there any compatibility concerns with existing wire preparation or assembly tooling?

A: No. Both parts use identical IDC termination and support the same 32-36 AWG wire gauge range. Existing wire preparation and crimping processes are fully compatible with the substitute.

Q: Does the packaging difference (bulk versus bag) affect component performance?

A: No. Packaging format does not affect electrical or mechanical performance. The difference is purely logistical and relates to procurement and inventory management.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the 08CH-A-08-IDC and 08CH-A-08-G-IDC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
