TE Connectivity AMP Connectors 641214-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 641214-7 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features a 7-position configuration with 0.100" (2.54mm) pitch spacing, suitable for board-to-cable/wire connections in general-purpose applications. The part operates across a temperature range of -55°C to 105°C with a 250VAC voltage rating.

The 641214-7 carries an obsolete product status, which necessitates identification of active equivalent components for ongoing design support and procurement continuity. Substitute parts maintain identical electrical and mechanical specifications while offering improved availability and current manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 641214-7 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 3-641214-7 maintains identical specifications in the following key areas:

Electrical Parameters: Pitch spacing (0.100" / 2.54mm), number of positions (7), contact type (male pin), voltage rating (250VAC), and operating temperature range (-55°C to 105°C) are identical between the main part and substitute.

Mechanical Parameters: Mounting configuration (through hole, right angle), shrouding style (shrouded - 1 wall), contact dimensions (mating length 0.295", post length 0.140"), insulation height (0.225"), and contact shape (square) are fully matched.

Material & Finish Specifications: Contact finish (gold at 30.0µin / 0.76µm thickness), contact material (copper alloy), insulation material (thermoplastic), and flammability rating (UL94 V-0) are consistent across both parts.

Series Designation: Both parts belong to the MTA-100 series, confirming functional and dimensional compatibility.

The primary distinction between the main part and substitute relates to product status and regulatory compliance, not to functional or physical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 3-641214-7 substitute part is the direct equivalent for the obsolete 641214-7. Selection of the substitute is based on the following engineering criteria:

Product Status Alignment: The 641214-7 carries obsolete status, limiting long-term procurement viability. The 3-641214-7 maintains active product status, ensuring continued manufacturing support and availability.

Regulatory Compliance: The substitute part 3-641214-7 achieves RoHS compliance, whereas the main part is RoHS non-compliant. For applications subject to RoHS directives or customer requirements, the substitute provides regulatory alignment.

REACH Compliance: The substitute part carries REACH Unaffected status, providing clarity on chemical substance compliance. The main part lists REACH status as vendor undefined.

Functional Equivalence: All electrical and mechanical parameters are identical between the two parts. The connector maintains the same 7-position, 2.54mm pitch configuration, through-hole right-angle mounting, gold-plated contacts, and operating specifications. Direct substitution in existing designs is supported without modification to PCB layouts or mating connector specifications.

Packaging Consideration: The substitute is supplied in bulk packaging, whereas the main part packaging is unspecified. Bulk packaging does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 3-641214-7 be used as a direct replacement for the 641214-7 in existing designs?

A: Yes. The 3-641214-7 is a direct functional equivalent. All electrical parameters (voltage rating, operating temperature, current capacity), mechanical dimensions (pitch, contact lengths, insulation height), and material specifications (contact finish, flammability rating) are identical. No PCB layout modifications or connector redesign is required.

Q: What is the primary reason for substituting the 641214-7?

A: The 641214-7 is classified as obsolete, which restricts procurement options and manufacturing support. The 3-641214-7 maintains active product status, ensuring reliable long-term availability and continued vendor support.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The 3-641214-7 is RoHS compliant, whereas the original 641214-7 is RoHS non-compliant. For applications requiring RoHS compliance, the substitute satisfies regulatory requirements.

Q: Are the contact specifications identical between the two parts?

A: Yes. Both parts feature gold-plated contacts with 30.0µin (0.76µm) thickness, copper alloy contact material, square contact shape, and identical mating and post lengths (0.295" and 0.140" respectively).

Q: What is the pitch spacing for this connector?

A: The pitch spacing is 0.100" (2.54mm) for both the main part and substitute. This spacing is standard for the MTA-100 series and determines compatibility with mating connectors and PCB footprints.

Q: Does packaging type affect connector performance?

A: No. The substitute part is supplied in bulk packaging, while the main part packaging is unspecified. Packaging type does not affect electrical performance, mechanical fit, or contact characteristics.

Q: What is the operating temperature range?

A: Both parts operate across -55°C to 105°C, providing consistent thermal performance across industrial and commercial temperature environments.

Q: Is the connector suitable for high-voltage applications?

A: The connector is rated for 250VAC, making it suitable for general-purpose applications within this voltage specification. Current capacity varies by wire gauge used in the mating cable assembly.
