TE Connectivity 749621-8 D-Type Plug Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 749621-8 is an 80-position D-Type plug connector with male pins, designed for IDC ribbon cable termination. This connector belongs to the AMPLIMITE .050 III series and is classified as a free-hanging, in-line connector with shielded construction. The part maintains active product status and is currently available with 753 pieces in stock.

D-Type connectors of this configuration are essential in applications requiring high-density signal transmission with standardized D-sub form factors. Substitute parts are identified to address inventory availability, compliance requirements, or alternative sourcing needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 749621-8 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters: Connector type (Plug, Male Pins), number of positions (80), row configuration (2 rows), pitch and row spacing (0.050 Pitch x 0.100 Row to Row), current rating (1A), and voltage rating (30V).

Mechanical Parameters: Shell size and layout, mounting type (Free Hanging, In-Line), shell material and finish (Steel, Tin-Nickel Plated), contact material (Phosphor Bronze), and contact finish (Gold).

Environmental & Compliance Parameters: Operating temperature range (-55°C to 105°C), material flammability rating (UL94 V-0), dielectric material (Thermoplastic), and moisture sensitivity level (1).

Termination Compatibility: IDC ribbon cable termination method.

The substitute part 5749621-8 meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 749621-8 and 5749621-8 are active products from TE Connectivity AMP Connectors and are electrically and mechanically equivalent. Selection between these parts should be based on the following factors:

Compliance Requirements: The substitute part 5749621-8 carries explicit RoHS Compliant status and REACH Unaffected designation, whereas the main part 749621-8 lists RoHS status as "Not applicable" and REACH status as "Vendor Undefined." Applications subject to RoHS or REACH regulatory frameworks should specify the 5749621-8.

Inventory Availability: The substitute part 5749621-8 has 1343 pieces in stock compared to 753 pieces for the main part 749621-8. For applications requiring immediate or bulk procurement, the substitute offers superior availability.

Functional Equivalence: Both parts are fully interchangeable in applications requiring 80-position D-Type plug connectors with IDC ribbon cable termination, operating within the -55°C to 105°C temperature range at 1A and 30V ratings.

Frequently Asked Questions (FAQ)

Q: Are the 749621-8 and 5749621-8 electrically interchangeable?

A: Yes. Both connectors are 80-position D-Type plugs with identical electrical ratings (1A, 30V), contact materials (Phosphor Bronze with gold finish), and operating temperature ranges (-55°C to 105°C). They are direct electrical equivalents.

Q: Can the 5749621-8 be used as a drop-in replacement for the 749621-8?

A: Yes. The connectors are mechanically identical in shell size (0.050 Pitch x 0.100 Row to Row), mounting type (Free Hanging, In-Line), and termination method (IDC, Ribbon Cable). No design modifications are required for substitution.

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

A: The 5749621-8 is explicitly RoHS Compliant and REACH Unaffected, while the 749621-8 lists RoHS status as "Not applicable" and REACH status as "Vendor Undefined." For applications in regulated markets, the 5749621-8 provides documented compliance assurance.

Q: Do both connectors support the same ribbon cable specifications?

A: Yes. Both parts use IDC (Insulation Displacement Contact) termination for ribbon cable and are designed for the AMPLIMITE .050 III series with identical pitch and row spacing specifications.

Q: Which part should be selected for new designs?

A: The 5749621-8 is recommended for new designs due to explicit RoHS compliance certification and higher inventory availability. Both parts are active products suitable for production use.

Q: Are there any environmental or temperature limitations that differ between these parts?

A: No. Both connectors operate across the identical temperature range of -55°C to 105°C and carry the same UL94 V-0 flammability rating. Environmental performance is equivalent.

Q: What is the significance of the different HTSUS codes?

A: The HTSUS codes (8536.69.4051 for 749621-8 and 8536.69.8000 for 5749621-8) reflect tariff classification differences but do not indicate functional or electrical differences. Both parts are classified as electrical connectors.
