Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640468-4 is determined by strict alignment with critical electrical and mechanical parameters. All substitute parts must maintain identical specifications for connector type (receptacle), number of positions (4), pitch (0.100"), contact type (female socket), cable termination method (IDC), wire gauge (22 AWG), mounting type (free hanging in-line and right angle), fastening type (locking ramp), and series designation (MTA-100).

Secondary parameters including contact finish material (tin-lead versus tin), packaging format (bulk versus tape & reel), and RoHS compliance status do not prevent substitution but may influence procurement decisions based on application requirements and regulatory mandates. The base product number 640468 remains constant across all qualified substitutes, confirming functional equivalence within the MTA-100 connector family.

Engineering Selection Recommendations

The TE Connectivity 3-640468-4 is a direct functional equivalent to the 640468-4 and qualifies as a primary substitute part. Both components share identical critical specifications across connector architecture, electrical interface, and mechanical mounting characteristics.

Selection based on compliance requirements: If RoHS3 compliance is mandated by application or regulatory standards, the 3-640468-4 substitute is the appropriate choice. The main part 640468-4 carries RoHS non-compliant status and is unsuitable for applications requiring lead-free or restricted substance compliance.

Selection based on packaging requirements: The main part 640468-4 is supplied in bulk packaging, while the 3-640468-4 substitute is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and high-volume manufacturing environments. Bulk packaging may be preferred for manual assembly or lower-volume applications.

Selection based on contact finish: The main part features tin-lead contact finish, while the substitute features tin contact finish. Both finishes provide equivalent electrical performance and contact reliability at the specified contact finish thickness of 80.0µin (2.03µm). Contact finish selection does not affect functional compatibility.

Both parts are currently active in production with adequate inventory availability (935 units for 640468-4 and 990 units for 3-640468-4).

Frequently Asked Questions (FAQ)

Q: Can the 3-640468-4 be used as a direct replacement for the 640468-4 in existing designs?

A: Yes. The 3-640468-4 is functionally equivalent to the 640468-4 across all critical electrical and mechanical parameters. Both connectors are 4-position MTA-100 series receptacles with identical pitch, contact type, IDC termination, wire gauge, and mounting specifications. The parts are interchangeable from a design and assembly perspective.

Q: What is the difference between tin-lead and tin contact finishes on these connectors?

A: The main part 640468-4 uses tin-lead contact finish, while the substitute 3-640468-4 uses tin contact finish. Both finishes are applied at 80.0µin (2.03µm) thickness and provide equivalent electrical conductivity and contact reliability. The primary distinction is regulatory: tin-lead finishes are associated with RoHS non-compliance, while tin finishes support ROHS3 compliance. Contact finish selection does not affect electrical performance or mechanical compatibility.

Q: Why does the 3-640468-4 have ROHS3 compliance while the 640468-4 does not?

A: The 3-640468-4 uses tin contact finish, which is lead-free and compliant with ROHS3 (Restriction of Hazardous Substances Directive 3). The 640468-4 uses tin-lead contact finish, which contains lead and does not meet ROHS3 requirements. If your application or supply chain mandates RoHS compliance, the 3-640468-4 is the required choice.

Q: What is the significance of Tape & Reel packaging for the 3-640468-4?

A: Tape & Reel (TR) packaging is the standard format for automated pick-and-place assembly equipment used in high-volume manufacturing. The 3-640468-4 in TR format integrates directly into automated assembly workflows. The main part 640468-4 in bulk packaging is suitable for manual assembly or lower-volume production runs. Packaging format does not affect connector performance or electrical characteristics.

Q: Are there any performance differences between the two parts?

A: No. Both the 640468-4 and 3-640468-4 deliver identical electrical performance and mechanical reliability. They share the same connector architecture, contact design, pitch, wire gauge rating, and fastening mechanism. Differences are limited to contact finish material, packaging format, and regulatory compliance status.

Q: Can I mix 640468-4 and 3-640468-4 connectors in the same assembly?

A: Yes. Both connectors are mechanically and electrically compatible and can be used together in the same assembly without functional impact. However, mixing parts with different RoHS compliance statuses may create documentation and traceability challenges in regulated manufacturing environments. Consistency in part selection is recommended for supply chain management and quality documentation purposes.

Q: What inventory levels are available for each part?

A: The main part 640468-4 has 935 units in stock. The substitute part 3-640468-4 has 990 units in stock. Both parts are actively produced and available for immediate procurement.
