Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity 207528-9 qualifies as a direct substitute for the 207528-3 based on identical electrical and mechanical parameters. Both parts share the same core specifications: 12-position header configuration, 0.197" (5.00mm) pitch, 3-row layout, through-hole mounting, 600V voltage rating, 7.5A current capacity, and -55°C to 130°C operating temperature range. The connectors maintain identical contact geometry, mating contact finish (gold plating at 30.0µin thickness), insulation material (polyamide/nylon), and fastening mechanism (latch holder with mounting flange).

The substitution is valid based on the following key parameters:

• Connector type, position count, and pitch configuration
• Electrical ratings (voltage and current)
• Temperature operating range
• Contact material and mating finish specification
• Mounting and termination method
• Flammability and safety certifications

Differences between the parts are limited to packaging format and post-side contact finish specification, which do not affect functional compatibility in the application.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 207528-9 serves as a functional equivalent to the 207528-3 for applications requiring identical electrical and mechanical performance. Both connectors meet the same voltage (600V) and current (7.5A) specifications, operate across the identical temperature range (-55°C to 130°C), and maintain equivalent contact geometry and mating characteristics.

Selection between these parts should be based on the following criteria:

207528-3 (Bulk Packaging): Select this part number when bulk packaging is acceptable and RoHS non-compliance is permissible for the application. This configuration is suitable for applications without regulatory RoHS requirements.

207528-9 (Tray Packaging, ROHS3 Compliant): Select this part number when ROHS3 compliance is required or when tray packaging is preferred for handling and inventory management. This configuration meets current regulatory standards for restricted substances and is suitable for applications subject to RoHS directives.

The post-side contact finish difference (tin-lead versus tin) does not affect functional compatibility, as both finishes provide equivalent solderability and electrical performance in through-hole solder termination applications.

Frequently Asked Questions (FAQ)

Q: Are the 207528-3 and 207528-9 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 12-position configuration, 0.197" (5.00mm) pitch, 3-row layout, insulation height (0.565"), contact length (0.181"), and mounting flange design. They are directly interchangeable in board-to-cable/wire applications.

Q: What is the difference in contact finish between these two parts?

A: The 207528-3 features tin-lead plated posts, while the 207528-9 features tin-plated posts. Both finishes provide equivalent solderability and electrical performance for through-hole solder termination. The mating contact finish (gold plating) is identical on both parts.

Q: Does the packaging difference affect the connector performance?

A: No. The 207528-3 is supplied in bulk packaging, while the 207528-9 is supplied in tray packaging. Packaging format does not affect electrical or mechanical performance. Selection should be based on inventory management and handling requirements.

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

A: The 207528-9 is ROHS3 compliant and should be selected for applications subject to RoHS directives. The 207528-3 is RoHS non-compliant and is suitable only for applications without RoHS requirements.

Q: Are both parts rated for the same voltage and current?

A: Yes. Both the 207528-3 and 207528-9 are rated for 600V voltage and 7.5A current capacity. They are electrically equivalent for power distribution applications.

Q: What is the operating temperature range for these connectors?

A: Both connectors operate across the identical temperature range of -55°C to 130°C, with UL94 V-0 flammability rating for the insulation material.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. The connectors are functionally equivalent and can be substituted for one another without design modification. Selection should be based on packaging preference and regulatory compliance requirements.
