TE Connectivity 1-643815-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-643815-1 is an 11-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a closed-end receptacle with a 0.100" (2.54mm) pitch in a single-row configuration. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide procurement flexibility, support supply chain continuity, and accommodate specific packaging or finish requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-643815-1 is determined by strict equivalence across the following critical parameters: connector type (receptacle), number of positions (11), pitch (0.100"), number of rows (1), cable termination method (IDC), wire gauge (26 AWG), contact type (female socket), mounting type (free hanging in-line and right angle), fastening type (locking ramp), contact finish thickness (80.0µin), and closed-end feature. The substitute part 4-643815-1 maintains all these parameters identically. The primary distinction between the main part and its substitute is the contact finish specification: the main part features tin-lead finish, while the substitute features tin finish. Both parts share the same base product number (643815), series designation (MTA-100), RoHS compliance status, MSL rating, and electrical/mechanical specifications. Packaging configuration differs between the two parts, with the main part supplied in standard packaging and the substitute in bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-643815-1 and 4-643815-1 are active production parts from TE Connectivity with full RoHS compliance and identical electrical and mechanical specifications. Selection between these parts is based on contact finish requirements and packaging needs. The 1-643815-1 with tin-lead finish is suitable for applications where tin-lead contact plating is specified or preferred. The 4-643815-1 with tin finish provides an alternative where tin plating meets application requirements. Both parts maintain the same contact finish thickness (80.0µin), pitch tolerance, and IDC termination compatibility with 26 AWG cable. The MSL 1 rating indicates both parts have unlimited shelf life under standard storage conditions. Packaging differences (standard versus bulk) should be evaluated based on procurement volume and inventory management requirements. Both parts are suitable for direct substitution in applications where the specified contact finish is compatible with the end-use environment.

Frequently Asked Questions (FAQ)

Q: Can the 4-643815-1 be used as a direct replacement for the 1-643815-1?

A: Yes. Both parts are mechanically and electrically identical 11-position MTA-100 series receptacles with 0.100" pitch, IDC termination for 26 AWG cable, and identical contact finish thickness. The primary difference is contact finish material: tin-lead versus tin. Direct substitution is valid where the tin finish of the 4-643815-1 meets application requirements.

Q: What is the significance of the contact finish difference between these parts?

A: The 1-643815-1 features tin-lead contact finish while the 4-643815-1 features tin finish. Both maintain 80.0µin (2.03µm) thickness. Contact finish selection depends on application-specific requirements including solderability, corrosion resistance, and compatibility with mating connector materials. Both finishes are RoHS compliant.

Q: Are there packaging differences between these substitute parts?

A: Yes. The 1-643815-1 is supplied in standard packaging, while the 4-643815-1 is supplied in bulk packaging. Packaging selection should align with procurement volume, handling procedures, and inventory management practices.

Q: Do both parts support the same cable termination specifications?

A: Yes. Both the 1-643815-1 and 4-643815-1 utilize IDC (Insulation Displacement Contact) termination and are compatible with 26 AWG discrete or ribbon cable. Termination specifications, pitch, and contact geometry are identical.

Q: What is the MSL rating for these connectors?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating unlimited shelf life under standard storage conditions. No moisture bake-out is required prior to assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1-643815-1 and 4-643815-1 are RoHS compliant and suitable for applications requiring RoHS certification.
