Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Type plug connectors is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish whether a part qualifies as a direct substitute for the TE Connectivity 749111-1:

Mandatory Equivalence Parameters:

• Connector type: Plug with male pins
• Number of positions: 20
• Number of rows: 2
• Shell size and connector layout: 0.050 Pitch x 0.100 Row to Row
• Termination method: IDC, Ribbon Cable
• Current rating: 1A
• Voltage rating: 30V
• Operating temperature range: -55°C ~ 105°C
• Shell material and finish: Steel, Tin-Nickel Plated
• Contact finish: Gold
• Contact material: Phosphor Bronze
• Dielectric material: Thermoplastic
• Features: Shielded
• Material flammability rating: UL94 V-0

Variable Parameters (Non-Substitution Factors):

• Packaging configuration (Bulk vs. Tube)
• RoHS compliance status
• REACH compliance status
• Inventory quantity
• HTSUS classification

The substitute part 5749111-1 maintains complete electrical and mechanical equivalence to the main part while differing only in packaging and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 749111-1 and 5749111-1 are functionally equivalent D-Type plug connectors suitable for identical circuit applications. Selection between these parts is determined by specific project requirements rather than electrical or mechanical performance differences.

749111-1 Selection Criteria:

• Bulk packaging requirement for high-volume assembly operations
• Projects with RoHS non-compliance acceptance or exemption
• Applications where existing inventory of non-compliant components is acceptable

5749111-1 Selection Criteria:

• Tube packaging requirement for component handling and storage
• Projects requiring ROHS3 compliance certification
• Applications subject to regulatory frameworks mandating RoHS compliance
• Situations where higher inventory availability (3004 pcs vs. 701 pcs) supports supply chain continuity

Both parts maintain identical electrical performance across the specified voltage (30V), current (1A), and temperature (-55°C ~ 105°C) operating ranges. Both are certified to UL94 V-0 flammability standards and feature identical contact materials, shell construction, and termination methods.

Frequently Asked Questions (FAQ)

Q: Can 5749111-1 be used as a direct replacement for 749111-1 in existing designs?

A: Yes. The 5749111-1 maintains complete electrical and mechanical equivalence to 749111-1. All functional parameters including connector type, pin count, pitch, termination method, current rating, voltage rating, temperature range, and contact materials are identical. The parts differ only in packaging configuration and RoHS compliance status.

Q: What is the difference between Bulk and Tube packaging?

A: Bulk packaging supplies components in loose form suitable for automated assembly equipment. Tube packaging supplies components in organized plastic tubes, typically used for manual assembly, component storage, or applications requiring individual component handling. Both packaging types contain identical connector components.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material sourcing standards, not electrical or mechanical performance. Both 749111-1 and 5749111-1 deliver identical electrical characteristics and are suitable for the same circuit applications.

Q: Are these connectors compatible with the same mating receptacles?

A: Yes. Both 749111-1 and 5749111-1 are plug connectors with identical shell size (0.050 Pitch x 0.100 Row to Row), pin count (20 positions), and row configuration (2 rows). Both mate with identical D-Type receptacles designed for the AMPLIMITE .050 III series.

Q: What is the significance of the gold contact finish?

A: Gold plating on phosphor bronze contacts provides corrosion resistance and ensures reliable electrical contact over the connector's operating life. Both parts feature identical gold contact finish specifications.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both 749111-1 and 5749111-1 are rated for continuous operation across the -55°C to 105°C temperature range. The thermoplastic dielectric material and phosphor bronze contacts maintain performance throughout this range.

Q: What does the shielded feature provide?

A: Shielding reduces electromagnetic interference (EMI) and radio frequency interference (RFI) in signal transmission. Both parts feature identical shielded construction with steel shells and tin-nickel plating.

Q: Are these connectors suitable for ribbon cable termination?

A: Yes. Both 749111-1 and 5749111-1 feature IDC (Insulation Displacement Contact) termination, designed specifically for direct ribbon cable connection without stripping or soldering.
