Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector contacts is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

• Manufacturer and series consistency (TE Connectivity AMP Connectors, Power Triple Lock, Standard)
• Contact type and gender (Female Blade Sockets)
• Termination method (Crimp)
• Wire gauge capacity (18 AWG)
• Contact finish material and specification (Tin)
• Compliance certifications (ROHS3 Compliant, MSL 1)

The substitute part 1971787-2 maintains identical specifications across all critical parameters while differing only in packaging configuration and product status. This part is currently active in production, providing direct functional equivalence for applications requiring the 1971787-1 contact.

Parameter Comparison

Engineering Selection Recommendations

The 1971787-2 is the direct equivalent substitute for the obsolete 1971787-1. Both parts share identical electrical and mechanical specifications within the Power Triple Lock series, including contact type, termination method, wire gauge, and contact finish. The 1971787-2 maintains full ROHS3 compliance and MSL 1 rating, ensuring compatibility with existing design requirements.

The primary distinction between these parts is product status and packaging. The 1971787-2 is currently in active production with established supply availability, whereas the 1971787-1 is obsolete. For new designs or component replenishment, the 1971787-2 provides continuity of function and specification without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 1971787-2 directly replace the 1971787-1 in existing assemblies?

A: Yes. Both parts are identical in electrical and mechanical function. They share the same wire gauge capacity (18 AWG), contact termination method (crimp), contact finish (tin), and series designation (Power Triple Lock, Standard). No design changes are required for substitution.

Q: What is the difference between these two part numbers?

A: The 1971787-1 and 1971787-2 differ in product status and packaging. The 1971787-1 is obsolete with unspecified packaging, while the 1971787-2 is active in production and supplied in Cut Tape (CT) packaging. All functional specifications remain identical.

Q: Are there compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating. Compliance certifications are equivalent across both part numbers.

Q: What wire gauge does this contact support?

A: Both the 1971787-1 and 1971787-2 are rated for 18 AWG wire gauge with crimp termination.

Q: Is the Cut Tape packaging of the 1971787-2 compatible with standard assembly processes?

A: Cut Tape (CT) packaging is a standard format for component distribution and is compatible with automated and manual assembly processes. Packaging selection depends on production volume and assembly equipment specifications.
