Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 207541-6 serves as the direct functional equivalent to the obsolete 207541-1. Both components maintain identical electrical and mechanical specifications across all critical parameters including pitch spacing, position count, current and voltage ratings, operating temperature range, and physical mounting configuration.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 207541-1 is classified as obsolete and carries RoHS non-compliant status. The 207541-6 is an active product with RoHS compliant certification, making it the appropriate selection for new designs and production applications subject to modern regulatory requirements.

Contact finish composition differs between the two parts: the 207541-1 features Tin-Lead plating while the 207541-6 uses Tin plating. Both maintain identical finish thickness specifications of 150.0µin (3.81µm) on mating and post contacts. This difference reflects the transition to lead-free manufacturing standards and does not affect electrical or mechanical compatibility in applications where the original Tin-Lead finish was acceptable.

Both parts are available in production quantities with established supply chains. The 207541-6 is recommended for all new applications and as the replacement for existing 207541-1 installations requiring component refresh or redesign.

Frequently Asked Questions (FAQ)

Q: Can the 207541-6 directly replace the 207541-1 in existing designs?

A: Yes. The 207541-6 maintains full electrical and mechanical compatibility with the 207541-1 across all critical parameters including pitch spacing, position count, current rating, voltage rating, operating temperature range, mounting configuration, and shrouding design. Both components are Metrimate series headers with identical through-hole, right-angle mounting and solder termination specifications.

Q: What is the significance of the contact finish difference between these parts?

A: The 207541-1 uses Tin-Lead contact finish while the 207541-6 uses Tin finish. Both maintain the same finish thickness of 150.0µin (3.81µm). This difference reflects the industry transition to lead-free manufacturing. The Tin finish on the 207541-6 provides equivalent electrical performance and corrosion resistance for the specified applications.

Q: Why is the 207541-1 classified as obsolete?

A: The 207541-1 is an older product variant that has been superseded by the 207541-6. The 207541-6 offers active product status, RoHS compliance, and lead-free manufacturing, making it the current standard offering from TE Connectivity for this connector configuration.

Q: Are there packaging differences between the 207541-1 and 207541-6?

A: The 207541-6 is supplied in Tube packaging. Packaging specifications for the 207541-1 were not provided in the available documentation. Confirm packaging requirements with your procurement specifications when transitioning between these parts.

Q: What applications are these connectors suitable for?

A: Both the 207541-1 and 207541-6 are rated for Automotive, General Purpose, and Industrial applications. The 7.5A current rating and 600V voltage rating support a wide range of low to medium-power interconnect requirements. The -55°C to 130°C operating temperature range accommodates both standard and elevated temperature environments.

Q: Are there any inventory considerations when selecting between these parts?

A: The 207541-6 is the active product with established ongoing supply. The 207541-1 is obsolete and available only from existing inventory. For new designs and long-term production requirements, the 207541-6 is the appropriate selection to ensure supply continuity and compliance with current regulatory standards.

Q: Do these connectors require any special handling or storage conditions?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard component storage practices are sufficient for these connectors.
