08CH-A-09-IDC Equivalent & Substitute Parts

Part Overview

The 08CH-A-09-IDC is a 9-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 currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08CH-A-09-IDC is determined by the following critical parameters that must remain constant:

• Connector Series & Mechanical Compatibility: Base product number 08CH-A ensures housing geometry and mounting interface alignment
• Electrical Interface: 9-position receptacle configuration with 0.031" (0.80mm) pitch and single-row layout
• Termination Method: IDC cable termination for discrete wire connections in 32-36 AWG range
• Physical Form Factor: Free hanging in-line mounting with friction lock fastening and closed-end design

The substitute part 08CH-A-09-G-IDC maintains all critical mechanical and electrical parameters while introducing a single material variation: gold contact finish with flash thickness replaces the tin finish of the original part.

Parameter Comparison

Engineering Selection Recommendations

The 08CH-A-09-G-IDC serves as a direct functional substitute for the discontinued 08CH-A-09-IDC. Both parts maintain identical mechanical interfaces, electrical pin configurations, and termination specifications. The primary distinction is the contact finish material: gold plating with flash thickness on the substitute part compared to tin on the original.

The substitute part carries active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications. The MSL rating of 1 (Unlimited) is identical across both parts, indicating no moisture sensitivity constraints during storage or handling.

Selection between these parts should be based on application-specific requirements regarding contact finish performance, corrosion resistance, and cost considerations. The gold finish of the substitute part provides enhanced contact reliability in certain environmental conditions compared to tin.

Frequently Asked Questions (FAQ)

Q: Can the 08CH-A-09-G-IDC replace the 08CH-A-09-IDC in existing designs?

A: Yes. Both connectors share identical mechanical form factors, pin counts, pitch spacing, and IDC termination methods. The housing geometry and mounting interface are fully compatible.

Q: What is the functional difference between tin and gold contact finishes?

A: Contact finish affects corrosion resistance and contact reliability under specific environmental conditions. Gold provides enhanced performance in high-humidity or corrosive environments, while tin is suitable for standard industrial applications.

Q: Are there packaging differences between these parts?

A: Yes. The 08CH-A-09-IDC is supplied in bulk packaging, while the 08CH-A-09-G-IDC is supplied in bag packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited).

Q: Why is the original part discontinued?

A: The 08CH-A-09-IDC is discontinued at DiGi Electronics. The 08CH-A-09-G-IDC remains in active production and is the recommended source for ongoing procurement.

Q: What wire gauges are supported by the substitute connector?

A: Both connectors support 32-36 AWG discrete wire termination via IDC method.
