TE Connectivity AMP Connectors 787131-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 787131-3 is a 68 Position Plug Connector with free hanging (in-line) mounting and IDC (Insulation Displacement Contact) termination. This connector belongs to the CHAMP .031 series and features center strip contacts with gold plating. The part is currently active in production and maintains unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when original inventory becomes unavailable, when alternative compliance certifications are required, or when packaging specifications differ from application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 787131-3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5787131-3 qualifies as a direct equivalent because it maintains identical specifications for:

• Number of positions (68)
• Row configuration (2 rows)
• Connector type (Plug)
• Mounting configuration (Free Hanging/In-Line)
• Termination technology (IDC)
• Contact style (Center Strip Contacts)
• Series designation (CHAMP .031)
• Contact finish and thickness (Gold, 30.0µin)
• Moisture sensitivity rating (MSL 1)

Differences between the main part and substitute are limited to packaging format and regulatory compliance status, which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both 787131-3 and 5787131-3 are functionally equivalent for applications requiring a 68-position, 2-row, free-hanging IDC plug connector with center strip contacts in the CHAMP .031 series.

Selection based on regulatory requirements:

• 787131-3 is appropriate for applications where RoHS non-compliance is acceptable or where legacy system compatibility is required.
• 5787131-3 is required for applications subject to ROHS3 compliance mandates or where regulatory documentation specifies RoHS3 certification.

Selection based on packaging:

• 5787131-3 is supplied in box packaging, which may be preferred for inventory management, storage, or shipping requirements where packaging format is specified.
• 787131-3 packaging format is not specified in available documentation.

Both parts maintain identical electrical and mechanical specifications, ensuring direct interchangeability in circuit design and PCB layout applications.

Frequently Asked Questions (FAQ)

Q: Can 5787131-3 be used as a direct replacement for 787131-3 in existing designs?

A: Yes. The 5787131-3 is electrically and mechanically equivalent to 787131-3. All critical parameters including position count, row configuration, mounting type, termination method, and contact specifications are identical. The substitute part maintains the same CHAMP .031 series designation and gold contact finish specifications.

Q: What is the primary difference between 787131-3 and 5787131-3?

A: The primary differences are RoHS compliance status and packaging format. The 5787131-3 is ROHS3 compliant, while 787131-3 is RoHS non-compliant. Additionally, 5787131-3 is supplied in box packaging. These differences do not affect connector performance or compatibility.

Q: Does the packaging difference between these parts affect connector performance?

A: No. Packaging format affects only storage, handling, and logistics. The connector itself and all functional specifications remain identical regardless of packaging type.

Q: Are there any electrical performance differences between these connectors?

A: No. Both connectors feature identical contact finish (gold at 30.0µin thickness), identical position configuration (68 positions in 2 rows), and identical termination technology (IDC). Electrical performance characteristics are equivalent.

Q: Which part should be selected for new designs?

A: For new designs, 5787131-3 is recommended due to ROHS3 compliance certification, which aligns with current regulatory standards and environmental requirements. However, 787131-3 remains a valid selection if legacy system compatibility or specific non-compliant specifications are required.

Q: Is the moisture sensitivity rating the same for both parts?

A: Yes. Both 787131-3 and 5787131-3 maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions for storage or handling.
