Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 207544-7 is the direct substitute for the obsolete 207544-3. Both parts share identical electrical ratings (600V, 7.5A), mechanical dimensions (16-position, 5.00mm pitch, through-hole right-angle mounting), and functional characteristics within the Metrimate series.

Key Advantages of 207544-7:

The substitute part maintains full electrical and mechanical compatibility while offering two significant improvements:

1. Product Status: The 207544-7 is classified as Active, ensuring continued availability and supply chain support for current and future production requirements.

2. Regulatory Compliance: The 207544-7 is RoHS Compliant, whereas the main part is RoHS non-compliant. This compliance status is critical for applications subject to RoHS directives and for manufacturers implementing lead-free manufacturing processes.

Contact Finish Consideration:

The 207544-7 features a Tin post finish compared to the Tin-Lead finish of the 207544-3. Both finishes maintain the identical 150.0µin (3.81µm) thickness specification and are functionally equivalent for solder termination applications. The Tin finish of the substitute aligns with lead-free manufacturing standards.

Packaging Difference:

The 207544-7 is supplied in Tube packaging, whereas the 207544-3 was supplied in bulk packaging. This packaging difference does not affect electrical or mechanical performance and reflects standard industry practice for active products.

Frequently Asked Questions (FAQ)

Q: Can the 207544-7 be used as a direct replacement for the 207544-3 in existing designs?

A: Yes. The 207544-7 is electrically and mechanically identical to the 207544-3. All critical parameters including voltage rating (600V), current rating (7.5A), connector pitch (5.00mm), number of positions (16), mounting type (through-hole right-angle), and operating temperature range (-55°C ~ 130°C) are identical. The parts are interchangeable in all applications.

Q: What is the significance of the RoHS compliance difference?

A: The 207544-7 is RoHS Compliant while the 207544-3 is RoHS non-compliant. RoHS compliance restricts the use of hazardous substances including lead. For new designs and applications subject to RoHS directives, the 207544-7 is the appropriate selection. For legacy systems where RoHS compliance is not required, either part functions identically.

Q: Does the Tin post finish of the 207544-7 differ functionally from the Tin-Lead finish of the 207544-3?

A: Both finishes are functionally equivalent for solder termination applications. Both maintain the same thickness specification (150.0µin / 3.81µm). The Tin finish of the 207544-7 reflects lead-free manufacturing standards and is compatible with standard solder processes.

Q: Are there any differences in mechanical fit or mounting between these parts?

A: No. Both parts have identical mechanical specifications: 16 positions, 5.00mm pitch, through-hole right-angle mounting, shrouded 4-wall design, mounting flange, and identical contact post length (0.192" / 4.88mm) and insulation height (0.500" / 12.70mm).

Q: What is the difference between bulk and tube packaging?

A: Bulk packaging typically refers to loose component packaging, while tube packaging contains components in a protective tube format. This packaging difference does not affect the electrical or mechanical performance of the connector. Tube packaging is standard for active products and provides improved component protection during storage and handling.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the 207544-3 and 207544-7 are rated for automotive applications, along with general purpose and industrial use. The operating temperature range of -55°C ~ 130°C and UL94 V-0 flammability rating support automotive environmental requirements.

Q: What is the current inventory status for these parts?

A: The 207544-3 has 1430 pieces in stock but is classified as obsolete. The 207544-7 has 744 pieces in stock and is classified as active. For new production, the 207544-7 is the recommended selection to ensure long-term supply availability.
