08CH-A-04-IDC Equivalent & Substitute Parts

Part Overview

The 08CH-A-04-IDC is a 4-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, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08CH-A-04-IDC is determined by strict equivalence across the following critical parameters:

• Connector Series & Geometry: Must belong to the 08CH series with identical 4-position configuration and 0.031" (0.80mm) pitch
• Electrical Interface: Receptacle connector with female socket contacts and IDC termination method
• Wire Compatibility: Support for 32-36 AWG discrete wire gauge
• Mechanical Interface: Free hanging in-line mounting with friction lock fastening
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part 08CH-A-04-G-IDC maintains full compatibility across all mechanical and electrical parameters. The primary distinction is the contact finish material (gold with flash thickness versus tin), which does not affect connector interchangeability for standard applications within the specified wire gauge range.

Parameter Comparison

Engineering Selection Recommendations

The 08CH-A-04-G-IDC serves as a direct functional substitute for the discontinued 08CH-A-04-IDC. Both parts maintain identical mechanical and electrical specifications across all critical parameters including connector geometry, contact configuration, termination method, and wire gauge compatibility.

The 08CH-A-04-G-IDC offers the additional advantage of active product status, ensuring continued availability and supply chain stability. Both parts satisfy ROHS3 compliance and REACH requirements, supporting regulatory obligations in current manufacturing environments.

The contact finish difference (gold flash versus tin) represents the sole material distinction between these parts. This variation does not affect connector interchangeability or performance within the specified 32-36 AWG wire gauge range for standard wire-to-board crimp applications.

Frequently Asked Questions (FAQ)

Q: Can the 08CH-A-04-G-IDC directly replace the 08CH-A-04-IDC in existing designs?

A: Yes. Both connectors share identical mechanical and electrical specifications including pitch, position count, contact type, termination method, and wire gauge compatibility. Direct substitution is supported without design modification.

Q: What is the significance of the contact finish difference between tin and gold?

A: Contact finish affects corrosion resistance and contact resistance characteristics. Gold finish provides enhanced corrosion resistance compared to tin. Both finishes are suitable for standard wire-to-board crimp applications within the specified wire gauge range.

Q: Are there packaging considerations when switching from the main part to the substitute?

A: The main part is supplied in bulk packaging, while the substitute is supplied in bag packaging. Procurement and inventory management processes may require adjustment to accommodate the different packaging format.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 08CH-A-04-IDC and 08CH-A-04-G-IDC are ROHS3 compliant and REACH unaffected, satisfying current regulatory standards for electronic component manufacturing and distribution.

Q: Why is the 08CH-A-04-IDC discontinued while the substitute remains active?

A: Product discontinuation decisions are based on market demand and manufacturing priorities. The 08CH-A-04-G-IDC remains in active production, providing continued availability for applications requiring this connector configuration.
