TE Connectivity 748826-2 D-Sub Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 748826-2 is a 25-position D-Sub plug connector with right-angle solder termination, designed for through-hole mounting applications. This connector belongs to the AMPLIMITE HD-20 series and features male pins with gold-flashed brass contacts. The part maintains active product status and is suitable for applications requiring signal-level connectivity with a 6A current rating at 125V. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility within the same connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 748826-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type classification (D-Sub Plug, Male Pins)
• Position count (25 positions)
• Row configuration (2 rows)
• Shell size and layout designation (3, DB, B)
• Mounting orientation (Through Hole, Right Angle)
• Termination technology (Solder)
• Current rating (6A)
• Voltage rating (125V)
• Contact material and finish specification (Brass with gold flash)
• Operating temperature range (-55°C to 105°C)
• Flange configuration (Housing/Shell, Unthreaded)
• Backset spacing (0.590" / 14.99mm)
• Series family (AMPLIMITE HD-20)

Parts meeting all these criteria are classified as direct substitutes within the same functional and mechanical envelope. Variations in RoHS compliance status do not preclude substitution eligibility when electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5748826-2 is a direct functional and mechanical equivalent to the 748826-2 within the AMPLIMITE HD-20 series. Both parts are active products from the same manufacturer and maintain identical electrical specifications, mechanical dimensions, and performance characteristics across all critical parameters.

The primary distinction between these parts is RoHS compliance status. The 748826-2 carries a "Not applicable" RoHS designation, while the 5748826-2 is explicitly RoHS Compliant. This difference reflects manufacturing process variations rather than functional capability differences. Both parts satisfy identical electrical requirements, thermal performance, and mechanical interface specifications.

Selection between these parts should be based on regulatory and procurement requirements specific to the end application. Applications subject to RoHS directives or customer specifications requiring RoHS compliance should utilize the 5748826-2. Applications without such requirements may use either part interchangeably from an engineering standpoint.

Both parts carry identical Moisture Sensitivity Level (MSL 1, Unlimited), ECCN classification (EAR99), and HTSUS coding (8536.69.4040), indicating equivalent handling, export, and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 5748826-2 be used as a direct replacement for the 748826-2 in existing designs?

A: Yes. The 5748826-2 is mechanically and electrically identical to the 748826-2. All pin configurations, contact spacing, mounting geometry, electrical ratings, and environmental specifications are equivalent. No design modifications are required for substitution.

Q: What is the difference between the RoHS status of these two parts?

A: The 748826-2 is marked "Not applicable" for RoHS compliance, while the 5748826-2 is RoHS Compliant. This reflects different manufacturing batches or process certifications. Both parts meet identical electrical and mechanical specifications. The RoHS designation indicates regulatory compliance documentation rather than functional performance differences.

Q: Are the contact finishes identical between these parts?

A: Yes. Both the 748826-2 and 5748826-2 feature gold-flashed brass contacts with identical finish thickness specifications. Contact resistance, durability, and electrical performance are equivalent.

Q: Do these connectors require different handling or storage procedures?

A: No. Both parts carry identical Moisture Sensitivity Level (MSL 1, Unlimited) ratings, indicating equivalent handling and storage requirements. No special moisture control measures are required for either part.

Q: Can these parts be mixed in the same assembly or production batch?

A: Yes. From an engineering standpoint, these parts are interchangeable. Both maintain identical mechanical interfaces, electrical performance, and environmental specifications. Assembly procedures, PCB layouts, and mating connector requirements are identical.

Q: What is the backset spacing, and is it identical between both parts?

A: The backset spacing for both the 748826-2 and 5748826-2 is 0.590 inches (14.99mm). This dimension defines the distance from the connector mounting face to the contact centerline and is identical for both parts, ensuring compatible mating with standard D-Sub receptacles.

Q: Are there any temperature or voltage derating considerations between these parts?

A: No. Both parts operate identically across the -55°C to 105°C temperature range with a 125V maximum voltage rating and 6A current capacity. No derating or performance differences exist between the two parts under any specified operating condition.

Q: What is the connector layout designation "3 (DB, B)," and is it the same for both parts?

A: Yes. The "3 (DB, B)" designation indicates a 25-position D-Sub connector with a specific pin arrangement standard. Both the 748826-2 and 5748826-2 use this identical layout, ensuring pin-for-pin compatibility with mating connectors designed for this configuration.
