Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 207444-8 serves as the direct active equivalent for the obsolete 207444-3. Both components share identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, current and voltage ratings, and operating temperature range.

Key Differentiators:

The 207444-8 offers two significant advantages over the 207444-3:

1. Product Status: The 207444-8 maintains active product status, ensuring long-term availability and continued manufacturer support. The 207444-3 is classified as obsolete and subject to discontinuation.

2. Regulatory Compliance: The 207444-8 is RoHS compliant, whereas the 207444-3 is RoHS non-compliant. This distinction is material for applications subject to RoHS regulations and for organizations implementing RoHS-compliant supply chains.

3. Contact Finish - Post: The 207444-8 utilizes Tin finish on the post termination, compared to Tin-Lead in the 207444-3. Both finishes are compatible with solder termination processes and deliver equivalent electrical performance.

For new designs and production applications, the 207444-8 is the appropriate selection. For field service or legacy system maintenance where the 207444-3 is currently installed, the 207444-8 provides direct functional replacement with enhanced compliance characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 207444-3 and 207444-8 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including mounting type (through hole), shrouding configuration (shrouded - 4 wall), pitch (5.00mm), row spacing (5.00mm), and all dimensional parameters. They mount identically on printed circuit boards and mate with the same receptacle connectors.

Q: What is the difference between Tin-Lead and Tin contact finishes on the post termination?

A: Both Tin-Lead and Tin finishes are acceptable for solder termination applications. The contact finish on the post does not affect electrical performance or solder joint quality. The 207444-8 uses Tin finish, which aligns with modern RoHS compliance requirements.

Q: Can I use the 207444-8 as a direct replacement for the 207444-3 in existing designs?

A: Yes. The 207444-8 is electrically and mechanically equivalent to the 207444-3 across all functional parameters. No design modifications are required for substitution. The 207444-8 is the recommended replacement for new production and field service applications.

Q: Why is the 207444-3 classified as obsolete?

A: The 207444-3 is an older product variant within the Metrimate series. TE Connectivity has transitioned to the 207444-8 as the active product offering. The 207444-8 provides equivalent functionality with improved compliance characteristics and active manufacturer support.

Q: What is the significance of RoHS compliance for this connector?

A: RoHS compliance indicates the connector meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. The 207444-8 is RoHS compliant, making it suitable for applications and markets requiring RoHS-compliant components. The 207444-3 is RoHS non-compliant due to its Tin-Lead contact finish.

Q: Are there packaging differences between the 207444-3 and 207444-8?

A: The 207444-3 packaging is not specified in the product data. The 207444-8 is supplied in Tray packaging. Both components are identical in form, fit, and function. Packaging differences do not affect connector performance or compatibility.

Q: What is the current availability of these parts?

A: The 207444-3 has 849 pieces in stock as new original inventory. The 207444-8 has 1098 pieces in stock as new original inventory. The 207444-8 is the active product with ongoing manufacturer support and supply continuity.

Q: Can I mix 207444-3 and 207444-8 connectors in the same assembly?

A: Yes. Both connectors are electrically and mechanically equivalent and can be used interchangeably within the same assembly or system without functional impact.
