Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 1-963743-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (MCP 6.3/4.8K)
• Contact type (Tab)
• Contact termination method (Crimp)
• Wire gauge rating (14-16 AWG)
• Contact finish material (Tin)
• Contact finish thickness (39.4µin / 1.00µm)
• Manufacturer (TE Connectivity AMP Connectors)
• Regulatory compliance (RoHS, REACH)

The substitute part 1-962918-1 maintains identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the substitute is active and available in production quantities, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-962918-1 is the direct functional equivalent for the obsolete 1-963743-1. Both components share identical electrical and mechanical specifications within the MCP 6.3/4.8K series, including wire gauge rating, contact termination method, finish material, and finish thickness.

The substitute part 1-962918-1 carries active product status with ROHS3 compliance certification, exceeding the RoHS compliance level of the original part. Both components maintain REACH Unaffected status and MSL 1 rating, confirming compatibility with standard handling and storage protocols.

The packaging difference between loose piece and cut tape reflects standard industry practice for active production components. This packaging format does not affect electrical or mechanical performance in connector applications.

Frequently Asked Questions (FAQ)

Q: Can 1-962918-1 be used as a direct replacement for 1-963743-1 in existing designs?

A: Yes. Both components are identical in electrical and mechanical specifications, including wire gauge, contact termination, finish material, and finish thickness. The substitute maintains all required regulatory certifications.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates the substitute part is in current production and available in commercial quantities. The original part is no longer manufactured. Substitution is necessary to maintain supply chain continuity.

Q: Are there compliance differences between the original and substitute parts?

A: Both parts are RoHS compliant and REACH Unaffected. The substitute carries ROHS3 certification, which represents an updated compliance standard. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Does the packaging format affect connector performance?

A: No. Packaging format (loose piece versus cut tape) is a supply and handling specification only. It does not affect electrical performance, mechanical fit, or functional compatibility in connector assemblies.

Q: Are the contact finish specifications identical?

A: Yes. Both components feature tin contact finish at 39.4µin (1.00µm) thickness, ensuring equivalent electrical conductivity and corrosion resistance characteristics.

Q: What wire gauges are supported by this tab contact?

A: Both the original and substitute parts support 14-16 AWG wire gauges with crimp termination.
