Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 749699-5 with the active equivalent 5749699-5 is based on strict electrical and mechanical parameter equivalence. Both connectors maintain identical specifications across all critical functional parameters that determine connector compatibility and performance:

Key Parameters Determining Substitution Validity:

• Connector style, type, and gender (D-Type Receptacle, Female Sockets)
• Position count and row configuration (50 positions, 2 rows)
• Pitch and row-to-row spacing (0.050 Pitch x 0.100 Row to Row)
• Termination method (IDC, Ribbon Cable)
• Shell construction and material finish (Steel, Nickel Plated)
• Contact material and finish (Phosphor Bronze with Gold plating)
• Electrical ratings (1A current, 30V voltage)
• Operating temperature range (-55°C to 105°C)
• Shielding configuration and flammability rating (UL94 V-0)

The substitute part 5749699-5 differs only in product status (Active versus Obsolete) and RoHS compliance classification, with no impact on functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5749699-5 is the direct functional equivalent of the obsolete 749699-5. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 749699-5 is classified as obsolete, creating supply chain risk. The 5749699-5 maintains active product status with higher inventory availability (1598 pieces versus 710 pieces), ensuring long-term procurement viability.

Compliance and Certifications: The 5749699-5 achieves ROHS3 compliance, whereas the 749699-5 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 5749699-5 is the mandated selection. Both parts maintain identical UL94 V-0 flammability ratings and equivalent electrical performance specifications.

Functional Equivalence: All electrical and mechanical parameters are identical between the two parts. The connectors are mechanically and electrically interchangeable in all applications where the 749699-5 was originally specified.

Packaging Consideration: The 5749699-5 is supplied in bulk packaging, whereas the original part packaging is unspecified. Bulk packaging does not affect connector functionality or performance.

Frequently Asked Questions (FAQ)

Q: Are the 749699-5 and 5749699-5 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including D-Type style, 50-position configuration, 0.050 pitch spacing, 0.100 row-to-row spacing, and free-hanging in-line mounting. They are fully mechanically interchangeable.

Q: Are the 749699-5 and 5749699-5 connectors electrically interchangeable?

A: Yes. Both connectors have identical electrical specifications: 1A current rating, 30V voltage rating, phosphor bronze contacts with gold plating, and operating temperature range of -55°C to 105°C. They are fully electrically interchangeable.

Q: What is the difference between the 749699-5 and 5749699-5?

A: The primary differences are product status (obsolete versus active) and RoHS compliance (non-compliant versus ROHS3 compliant). All functional specifications are identical. The 5749699-5 also has higher inventory availability.

Q: Can I use the 5749699-5 as a replacement for the 749699-5 in existing designs?

A: Yes. The 5749699-5 is a direct substitute with identical electrical and mechanical specifications. No design modifications are required.

Q: Does the RoHS3 compliance of the 5749699-5 affect its performance compared to the non-compliant 749699-5?

A: No. RoHS3 compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both connectors deliver identical functional performance.

Q: What is the difference in packaging between these two parts?

A: The 749699-5 packaging is unspecified in available documentation. The 5749699-5 is supplied in bulk packaging. Packaging format does not affect connector functionality or performance characteristics.

Q: Are both connectors suitable for IDC ribbon cable termination?

A: Yes. Both the 749699-5 and 5749699-5 are designed for IDC (Insulation Displacement Contact) ribbon cable termination and are fully compatible with standard 50-position ribbon cables.

Q: What is the shielding configuration of these connectors?

A: Both connectors feature shielded construction with steel shells and nickel plating. The shielding provides electromagnetic interference protection for signal integrity in the 50-position D-Type configuration.
