TE Connectivity 207378-3 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 207378-3 is a Metrimate series rectangular connector header designed for through-hole, right-angle mounting applications. This component features a 6-position configuration with 0.197" (5.00mm) pitch spacing, shrouded 4-wall design, and gold-plated mating contacts rated for 7.5A at 600V. The 207378-3 is classified as obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements where the original part is no longer readily procurable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 207378-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Pitch spacing: 0.197" (5.00mm)
• Number of positions: 6
• Contact type: Male Pin
• Current rating: 7.5A
• Voltage rating: 600V
• Operating temperature range: -55°C ~ 130°C

Mechanical Compatibility Parameters:

• Connector type: Header
• Mounting type: Through Hole, Right Angle
• Shrouding configuration: Shrouded - 4 Wall
• Contact shape: Circular
• Insulation material: Polyamide (PA), Nylon
• Insulation height: 0.500" (12.70mm)
• Contact finish - mating: Gold

Functional Parameters:

• Series: Metrimate
• Fastening type: Latch Holder
• Termination: Solder
• Style: Board to Board or Cable

Substitute parts must maintain identical values across all listed parameters to ensure direct functional and mechanical interchangeability without design modification or re-qualification.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 207378-7 serves as the direct functional and mechanical substitute for the obsolete 207378-3. Both components share identical electrical ratings, mechanical dimensions, and connector specifications across all critical parameters.

Key Differentiation Factors:

The 207378-7 is classified as Active product status, ensuring ongoing manufacturer support and availability. The 207378-3 is Obsolete, making the 207378-7 the appropriate selection for new designs and production continuity.

The 207378-7 achieves ROHS3 compliance, whereas the 207378-3 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 207378-7 is the mandated selection.

The contact finish on the post differs between the two parts: the 207378-3 uses Tin-Lead finish while the 207378-7 uses Tin finish. Both maintain identical contact finish thickness of 150.0µin (3.81µm) on the post. This difference reflects the transition from lead-containing to lead-free soldering processes and does not affect electrical or mechanical interchangeability.

The 207378-7 is supplied in Tube packaging, whereas packaging information for the 207378-3 is not specified in the provided data.

For applications requiring component substitution, regulatory compliance, or new procurement, the 207378-7 is the appropriate selection. Both parts are suitable for automotive, general purpose, and industrial applications with identical operating temperature ranges and electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 207378-7 be used as a direct replacement for the 207378-3 in existing designs?

A: Yes. The 207378-7 is mechanically and electrically interchangeable with the 207378-3. Both components share identical pitch spacing (0.197" / 5.00mm), position count (6), mounting configuration (through-hole right-angle), shrouding design (4-wall), current rating (7.5A), voltage rating (600V), and operating temperature range (-55°C ~ 130°C). No design modification is required for substitution.

Q: What is the difference between the contact finishes on the post?

A: The 207378-3 features Tin-Lead contact finish on the post, while the 207378-7 features Tin finish. Both maintain the same contact finish thickness of 150.0µin (3.81µm). The Tin finish on the 207378-7 reflects compliance with lead-free soldering standards. Both finishes are compatible with standard PCB assembly processes.

Q: Why is the 207378-3 listed as Obsolete?

A: The 207378-3 is classified as Obsolete by the manufacturer, indicating it is no longer in active production. The 207378-7 is the Active variant that replaces it. For new designs and ongoing production, the 207378-7 should be specified.

Q: Does the 207378-7 meet RoHS requirements?

A: Yes. The 207378-7 is ROHS3 compliant. The 207378-3 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 207378-7 is the required selection.

Q: Are there any differences in packaging between these two parts?

A: The 207378-7 is supplied in Tube packaging. Packaging information for the 207378-3 is not specified in the available data. Packaging differences do not affect component functionality or interchangeability.

Q: What applications are these connectors suitable for?

A: Both the 207378-3 and 207378-7 are rated for Automotive, General Purpose, and Industrial applications. The identical operating temperature range of -55°C ~ 130°C and UL94 V-0 flammability rating support use across these application categories.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 207378-3 and 207378-7 are manufactured by TE Connectivity AMP Connectors and belong to the Metrimate series. They share the same base product number (207378) with different variant designations.
