Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 749085-5 D-Type plug connector is determined by strict equivalence across the following critical parameters:

Connector Architecture Parameters:

• Connector style: D-Type
• Connector type: Plug with male pins
• Number of positions: 50
• Number of rows: 2
• Shell size and connector layout: 0.050 pitch x 0.100 row-to-row spacing

Electrical Performance Parameters:

• Current rating: 1A
• Voltage rating: 30V
• Contact material: Phosphor Bronze
• Contact finish: Gold

Physical and Environmental Parameters:

• Mounting type: Through hole
• Termination method: Solder
• Operating temperature range: -55°C to 105°C
• Dielectric material: Liquid Crystal Polymer (LCP), Polyester
• Shielded feature: Required
• Flange feature: Housing/Shell (4-40)
• Material flammability rating: UL94 V-0

Compliance and Regulatory Parameters:

• ECCN: EAR99
• HTSUS: 8536.69.4040

Parts meeting all these parameters are classified as direct substitutes. Variations in product status, RoHS compliance, or REACH status do not affect functional substitutability when all electrical, mechanical, and environmental specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5749085-5 is a direct functional equivalent to the 749085-5 D-Type plug connector. Both parts share identical electrical performance specifications, mechanical dimensions, and environmental operating parameters. The parts are interchangeable for all applications requiring a 50-position D-Type plug with male pins, 0.050 pitch spacing, solder termination, and through-hole mounting.

The primary distinction between these parts lies in regulatory compliance status. The 5749085-5 carries ROHS3 compliance certification, whereas the 749085-5 is marked as not applicable for RoHS. Both parts are classified as obsolete products. The REACH status differs between the two parts, with the main part listed as REACH Affected and the substitute marked as Vendor Undefined. These compliance differences do not affect the functional substitutability of the connector in applications where the electrical and mechanical specifications are the governing selection criteria.

Both parts maintain identical ratings for current (1A), voltage (30V), operating temperature (-55°C to 105°C), and contact materials (Phosphor Bronze with gold finish). The shielded housing, UL94 V-0 flammability rating, and LCP/Polyester dielectric composition are consistent across both variants.

Frequently Asked Questions (FAQ)

Q: Can the 5749085-5 be used as a direct replacement for the 749085-5 in existing circuit board designs?

A: Yes. The 5749085-5 is a direct functional equivalent. Both connectors share identical pin counts (50 positions), row configuration (2 rows), pitch spacing (0.050 x 0.100), mounting type (through hole), and termination method (solder). Physical dimensions and electrical ratings are identical, allowing direct substitution in PCB layouts and solder reflow processes.

Q: Are there any differences in the contact interface between these two parts?

A: No. Both the 749085-5 and 5749085-5 use identical contact materials (Phosphor Bronze) and contact finish (gold). The connector interface, mating characteristics, and signal integrity performance are equivalent.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 5749085-5 carries ROHS3 compliance certification, while the 749085-5 is marked as not applicable for RoHS. This difference reflects regulatory classification at the time of manufacture or documentation. For applications subject to RoHS requirements, the 5749085-5 provides explicit compliance documentation. For applications without RoHS mandates, both parts are functionally equivalent.

Q: Do these connectors support the same current and voltage ratings?

A: Yes. Both the 749085-5 and 5749085-5 are rated for 1A current and 30V voltage. Operating temperature ranges are identical at -55°C to 105°C. These electrical specifications are interchangeable across both part numbers.

Q: What is the pitch spacing of these D-Type connectors?

A: Both connectors feature 0.050 pitch contact spacing with 0.100 row-to-row spacing. This configuration is standard for the AMPLIMITE .050 III series and determines compatibility with mating receptacles and PCB footprints.

Q: Are these connectors shielded?

A: Yes. Both the 749085-5 and 5749085-5 feature shielded housings with 4-40 mounting flanges. The shielding provides electromagnetic interference protection and is consistent across both part variants.

Q: What termination method is used for these connectors?

A: Both connectors use solder termination for through-hole PCB mounting. The solder pads and lead configurations are identical between the two parts, allowing use of the same assembly processes and equipment.

Q: Is there a difference in the dielectric material composition?

A: No. Both parts use identical dielectric materials: Liquid Crystal Polymer (LCP) and Polyester. The material composition affects electrical insulation properties, temperature stability, and flammability characteristics, all of which are equivalent between the 749085-5 and 5749085-5.

Q: What is the flammability rating for these connectors?

A: Both connectors carry a UL94 V-0 flammability rating, indicating compliance with UL 94 vertical flame test standards at the highest safety level. This rating is identical for both the 749085-5 and 5749085-5.

Q: Are these parts still in active production?

A: Both the 749085-5 and 5749085-5 are classified as obsolete products. Availability is limited to existing inventory. Current stock levels are 757 pieces for the 749085-5 and 725 pieces for the 5749085-5.
