Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 747497-4 with the active equivalent 5747497-4 is based on strict electrical and mechanical parameter equivalence. Both connectors maintain identical specifications across all critical functional parameters: 50-position configuration, 3-row layout, shell size 5 (DD, D), through-hole right-angle mounting, 6A current rating, 125V voltage rating, and operating temperature range of -55°C to 105°C. The shell material (steel, tin plated), contact material (brass), contact finish (gold), and flange configuration (mating side female screwlock 4-40) are identical between both parts.

The primary distinction between these parts is packaging format and product status. The 747497-4 is supplied in tube packaging with obsolete status, while the 5747497-4 is supplied in bulk packaging with active product status. The substitute part also provides improved RoHS compliance (RoHS Compliant versus RoHS non-compliant), making it suitable for applications requiring regulatory adherence.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5747497-4 serves as the direct functional equivalent for the obsolete 747497-4. Selection of the substitute part is appropriate for all applications currently utilizing the 747497-4, as electrical and mechanical parameters are fully equivalent. The 5747497-4 provides the additional advantage of active product status, ensuring continued availability and supply chain reliability.

For applications subject to RoHS compliance requirements, the 5747497-4 is the required selection, as it carries RoHS Compliant certification while the original part does not. Both connectors maintain identical performance characteristics across current rating (6A), voltage rating (125V), operating temperature range (-55°C to 105°C), and mechanical mounting specifications.

The bulk packaging format of the 5747497-4 is suitable for production environments and high-volume applications. Organizations requiring tube packaging should confirm packaging availability through the supplier, as the functional connector remains identical regardless of packaging format.

Frequently Asked Questions (FAQ)

Q: Are the 747497-4 and 5747497-4 electrically and mechanically interchangeable?

A: Yes. Both connectors are identical in all electrical and mechanical parameters, including pin count (50 positions), configuration (3-row, shell size 5), current rating (6A), voltage rating (125V), operating temperature range (-55°C to 105°C), and mounting type (through-hole, right-angle solder termination).

Q: What is the primary reason to transition from 747497-4 to 5747497-4?

A: The 747497-4 is classified as obsolete, while the 5747497-4 maintains active product status. This ensures continued availability, supply chain stability, and access to current manufacturing processes. Additionally, the 5747497-4 is RoHS Compliant, whereas the 747497-4 is not.

Q: Does the packaging difference between tube and bulk affect connector performance?

A: No. Packaging format does not affect electrical or mechanical performance. The tube packaging of the 747497-4 and bulk packaging of the 5747497-4 are distribution formats only. The connectors themselves are functionally identical.

Q: Can the 5747497-4 be used in applications originally designed for the 747497-4?

A: Yes. The 5747497-4 is a direct substitute for all applications utilizing the 747497-4. No design modifications or PCB layout changes are required.

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

A: RoHS compliance indicates the connector meets restrictions on hazardous substances. The 5747497-4 is RoHS Compliant, making it suitable for applications and markets requiring regulatory adherence. The 747497-4 is RoHS non-compliant and may not be acceptable for certain applications or regions with RoHS requirements.

Q: Are there any differences in contact finish or material between these parts?

A: No. Both connectors feature identical contact material (brass), contact finish (gold), shell material (steel, tin plated), and flange configuration (mating side female screwlock 4-40).

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

A: Both the 747497-4 and 5747497-4 operate across the identical temperature range of -55°C to 105°C.
