Substitute Part Grouping Explanation

Substitution of D-Type receptacle connectors is determined by strict equivalence across electrical and mechanical parameters. The primary criteria for substitution include connector style, connector type, position count, row configuration, shell size and pitch specifications, mounting methodology, termination type, current and voltage ratings, operating temperature range, shell material and finish, contact material and finish, and shielding characteristics.

The substitute part 5749069-1 maintains full electrical and mechanical compatibility with the main part 749069-1 across all specified parameters. Both connectors are 20-position D-Type receptacles with identical shell sizing (0.050 Pitch x 0.100 Row to Row), through-hole solder termination, 1A current rating, 30V voltage rating, and -55°C to 105°C operating temperature range. Both feature steel nickel-plated shells with phosphor bronze gold-plated contacts and shielded signal transmission. The flange configuration, latchblock and rail features, and UL94 V-0 flammability rating are identical across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the 749069-1 and 5749069-1 connectors are active products manufactured by TE Connectivity and are suitable for direct substitution in applications requiring 20-position D-Type receptacle connectors with the specified electrical and mechanical characteristics.

The 749069-1 carries RoHS Compliant certification, while the 5749069-1 carries ROHS3 Compliant certification. Both certifications satisfy RoHS requirements and are compatible for use in regulated applications. The 749069-1 is REACH Affected, while the 5749069-1 has Vendor Undefined REACH status.

Current inventory levels differ between the two parts: 749069-1 has 1116 pieces in stock, while 5749069-1 has 1888 pieces in stock. Availability considerations may influence part selection for procurement planning.

Both connectors are packaged in tubes and maintain identical electrical performance across all specified parameters including current rating, voltage rating, operating temperature range, and contact characteristics.

Frequently Asked Questions (FAQ)

Q: Can 5749069-1 be used as a direct replacement for 749069-1 in existing designs?

A: Yes. Both connectors are electrically and mechanically equivalent across all specified parameters including connector style, position count, shell sizing, termination method, current and voltage ratings, and operating temperature range. No design modifications are required for substitution.

Q: Are there differences in compliance certifications between these parts?

A: The 749069-1 is RoHS Compliant with REACH Affected status. The 5749069-1 is ROHS3 Compliant with Vendor Undefined REACH status. Both satisfy RoHS requirements. Applications subject to specific REACH regulations should verify vendor documentation for the 5749069-1 prior to selection.

Q: What is the significance of the shell size specification 0.050 Pitch x 0.100 Row to Row?

A: This specification defines the physical dimensions and contact spacing of the connector. The 0.050 pitch refers to the spacing between individual contacts within a row, while 0.100 row to row specifies the spacing between the two rows of contacts. Both substitute parts maintain identical spacing, ensuring mechanical compatibility with mating connectors and printed circuit board layouts.

Q: Are both connectors suitable for high-temperature applications?

A: Yes. Both the 749069-1 and 5749069-1 operate across the temperature range of -55°C to 105°C, making them suitable for applications requiring extended temperature performance within this specification.

Q: What is the current-carrying capacity of these connectors?

A: Both connectors are rated for 1A per contact at 30V. Applications requiring higher current capacity require alternative connector designs with higher current ratings.

Q: What packaging format is used for these connectors?

A: Both parts are supplied in tube packaging, suitable for automated assembly processes and standard component handling procedures.

Q: Are these connectors shielded?

A: Yes. Both the 749069-1 and 5749069-1 feature shielded construction, providing electromagnetic interference protection for signal transmission.

Q: What contact materials are used in these connectors?

A: Both connectors use phosphor bronze contacts with gold plating, providing reliable electrical contact and corrosion resistance across the operating temperature range.
