08CH-A-03-IDC Equivalent & Substitute Parts

Part Overview

The 08CH-A-03-IDC is a 3-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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08CH-A-03-IDC is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts must belong to the 08CH series
• Connector Configuration: Receptacle type with 3 positions
• Electrical Interface: IDC cable termination method
• Pitch and Spacing: 0.031" (0.80mm) pitch, single row configuration
• Wire Compatibility: Support for 32-36 AWG discrete wire
• Mounting Method: Free hanging (in-line) orientation with friction lock fastening
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The identified substitute part 08CH-A-03-G-IDC maintains equivalence across all mechanical and electrical parameters. The primary difference is the contact finish material (gold with flash thickness versus tin), which does not affect functional compatibility for this connector category.

Parameter Comparison

Engineering Selection Recommendations

The 08CH-A-03-G-IDC serves as a direct functional substitute for the discontinued 08CH-A-03-IDC. Both parts maintain identical mechanical and electrical specifications across all critical parameters including connector type, position count, pitch, termination method, and wire gauge compatibility.

The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability. The gold contact finish with flash thickness provides enhanced corrosion resistance compared to the tin finish of the original part, while maintaining full ROHS3 and REACH compliance.

Packaging differs between the two parts (bulk versus bag), which may affect procurement quantities and handling procedures but does not impact functional performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 08CH-A-03-G-IDC be used as a direct replacement for the 08CH-A-03-IDC?

A: Yes. Both parts are 3-position rectangular receptacle connectors within the 08CH series, sharing identical pitch (0.031"), mounting type (free hanging in-line), cable termination method (IDC), and wire gauge support (32-36 AWG). The contact finish difference does not affect functional compatibility.

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

A: Contact finish affects corrosion resistance and long-term reliability in specific environmental conditions. Gold with flash thickness provides superior corrosion resistance. Both finishes are suitable for standard industrial applications and maintain equivalent electrical performance.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings (1 - Unlimited). They meet the same regulatory requirements for industrial connector applications.

Q: Does packaging type affect connector performance or compatibility?

A: No. Packaging (bulk versus bag) is a logistics consideration only and does not impact electrical or mechanical performance. Selection should be based on procurement quantity requirements and handling procedures.

Q: Why is the original part discontinued?

A: Product discontinuation is a manufacturer decision typically driven by market demand, product line consolidation, or transition to newer designs. The active substitute part ensures design continuity without requiring circuit modifications.
