TE Connectivity 643232-2 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 643232-2 is a 5-position header connector from the Universal MATE-N-LOK series, designed for board-to-cable/wire applications. This through-hole, right-angle connector features gold-plated mating contacts and tin-lead plated posts for solder termination. The connector maintains an active product status and is currently available with 810 pieces in stock.

Identifying equivalent and substitute parts is necessary when addressing supply chain requirements, packaging preferences, or compliance specifications. The 643232-2 is classified as RoHS non-compliant, which may necessitate alternative sourcing for applications requiring RoHS3 compliance or bulk packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the TE Connectivity 643232-2 and equivalent parts is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type (Header)
• Number of positions (5)
• Pitch specification (0.250" / 6.35mm)
• Mounting configuration (Through Hole, Right Angle)
• Contact type (Female Socket)
• Termination method (Solder)
• Mating contact finish (Gold)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)

The substitute part 3-643232-0 maintains identical electrical and mechanical specifications across all critical parameters. Differences exist only in packaging configuration (bulk versus standard) and post-contact finish material (tin versus tin-lead), along with RoHS compliance status. These differences do not affect functional interchangeability in applications where the connector specifications are met.

Parameter Comparison

Engineering Selection Recommendations

643232-2 Selection Criteria: The 643232-2 is appropriate for applications where RoHS non-compliance is acceptable and standard packaging is required. This part maintains active product status and is available in adequate inventory quantities.

3-643232-0 Selection Criteria: The 3-643232-0 is the appropriate selection for applications requiring ROHS3 compliance. This substitute part is functionally equivalent across all electrical and mechanical parameters. The post-contact finish differs (tin versus tin-lead), but both finishes are compatible with standard solder termination processes. Bulk packaging is available for high-volume applications. This part also maintains active product status with higher inventory availability.

Both parts are manufactured by TE Connectivity and belong to the Universal MATE-N-LOK series, ensuring design continuity and interchangeability within the same connector family.

Frequently Asked Questions (FAQ)

Q: Are the 643232-2 and 3-643232-0 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 5-position configuration, 0.250" (6.35mm) pitch, gold-plated mating contacts with 30.0µin thickness, and phosphor bronze contact material. The difference in post-contact finish (tin-lead versus tin) does not affect electrical performance in solder termination applications.

Q: What is the primary difference between these two parts?

A: The primary differences are packaging configuration (standard versus bulk), post-contact finish material (tin-lead versus tin), and RoHS compliance status (non-compliant versus ROHS3 compliant). All mechanical and electrical specifications remain identical.

Q: Which part should be selected for RoHS-compliant applications?

A: The 3-643232-0 is ROHS3 compliant and is the appropriate selection for applications requiring RoHS compliance. The 643232-2 is RoHS non-compliant.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts are from the same Universal MATE-N-LOK series, feature identical mounting configurations (through-hole, right-angle), and maintain the same insulation material (polyamide/nylon) and flammability rating (UL94 V-0).

Q: Does the tin versus tin-lead post finish affect solder joint quality?

A: Both tin and tin-lead finishes are compatible with standard solder termination processes. The selection between them depends on application-specific requirements and soldering process parameters, not on connector interchangeability.

Q: What is the difference in packaging between these parts?

A: The 643232-2 is supplied in standard packaging, while the 3-643232-0 is supplied in bulk packaging. Bulk packaging is typically used for high-volume manufacturing operations.

Q: Are both parts currently available?

A: Yes. The 643232-2 has 810 pieces in stock, and the 3-643232-0 has 907 pieces in stock. Both parts maintain active product status.
