TE Connectivity AMP Connectors 794528-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 794528-1 is a rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This connector features a 6-position configuration with 0.165" (4.20mm) pitch spacing, shrouded 4-wall design, and solder termination with locking ramp fastening. The part is classified as obsolete, necessitating identification of active equivalent components that maintain functional and mechanical compatibility for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 794528-1 with the Molex 0353180620 is based on alignment of the following critical parameters:

Matched Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 6
• Number of Rows: 2
• Pitch - Mating: 0.165" (4.20mm)
• Row Spacing - Mating: 0.165" (4.20mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Locking Ramp
• Contact Shape: Square
• Insulation Material: Polyamide (PA), Nylon

These parameters define the mechanical and electrical interface compatibility between the main part and substitute. The Molex 0353180620 maintains identical mating pitch, position count, shrouding configuration, and mounting orientation, enabling direct functional substitution in applications requiring 6-position right-angle headers with 4.20mm pitch spacing.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0353180620 serves as a functional equivalent to the obsolete TE Connectivity 794528-1 based on matching mechanical and electrical interface parameters. The substitute part maintains identical mating pitch, position configuration, shrouding design, and mounting orientation.

Compliance Considerations:

The Molex 0353180620 holds active product status and ROHS3 compliance certification, providing advantages for new designs and applications subject to regulatory requirements. The TE Connectivity 794528-1 is classified as RoHS non-compliant and REACH Affected, reflecting its obsolete status.

Material and Finish Differences:

The substitute part features brass contact material with tin finish, compared to the original copper alloy with tin-lead finish. The Molex component exhibits UL94 V-2 flammability rating versus the original UL94 V-0 rating. These material differences do not affect mating compatibility but should be evaluated against specific application requirements for electrical performance and environmental exposure.

Dimensional Variations:

Minor dimensional differences exist in insulation height (0.378" versus 0.394") and contact post length (0.173" versus 0.138"). These variations remain within typical tolerance ranges for board-to-board and board-to-cable applications and do not compromise mechanical fit or electrical function.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0353180620 directly replace the TE Connectivity 794528-1 in existing applications?

A: The Molex 0353180620 maintains identical mating pitch (0.165"), position count (6), row spacing (0.165"), shrouding configuration (4-wall), and mounting type (through-hole right-angle). Direct mechanical and electrical substitution is supported for applications where the material and compliance differences do not impose constraints.

Q: What are the key differences between these two connectors?

A: Primary differences include product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), contact material (copper alloy versus brass), contact finish (tin-lead versus tin), flammability rating (UL94 V-0 versus UL94 V-2), and minor dimensional variations in insulation height and contact post length.

Q: Are there voltage or current rating differences that affect substitution?

A: The TE Connectivity 794528-1 specifies 600VAC voltage rating. The Molex 0353180620 does not provide explicit voltage or current ratings in the available specifications. Applications requiring specific voltage or current performance should be evaluated against manufacturer datasheets.

Q: Does the tin-lead to tin finish change affect solder compatibility?

A: Both connectors feature solder termination. The transition from tin-lead to tin finish reflects modern RoHS compliance requirements. Tin finish provides equivalent solder wetting and joint reliability in standard PCB assembly processes.

Q: What is the significance of the UL94 V-0 to UL94 V-2 flammability rating change?

A: UL94 V-0 represents superior flame resistance compared to UL94 V-2. Applications in high-temperature or flame-critical environments should confirm that UL94 V-2 rating meets specific safety requirements.

Q: Are the dimensional differences in contact length and insulation height critical?

A: The contact post length difference (0.138" versus 0.173") and insulation height difference (0.394" versus 0.378") reflect design variations between manufacturers. These differences remain within acceptable tolerances for standard board-to-board and board-to-cable applications. PCB layout and mating connector specifications should be verified for specific applications.

Q: What is the packaging difference between these parts?

A: The TE Connectivity 794528-1 packaging is not specified. The Molex 0353180620 is supplied in bulk packaging. Packaging format should be confirmed with suppliers based on production volume and handling requirements.
