Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub connectors is determined by strict equivalence across electrical and mechanical parameters. The primary substitution criteria for the 745053-2 are:

Electrical Parameters:

• Connector type (Plug, Male Pins)
• Number of positions (25)
• Current rating (6A)
• Voltage rating (125V)
• Contact material (Brass)
• Contact finish (Gold)

Mechanical Parameters:

• Shell size and connector layout (3, DB, B)
• Number of rows (2)
• Mounting type (Through Hole)
• Termination method (Solder)
• Dielectric material (Polyester)
• Flange feature (Housing/Shell 4-40)

Environmental & Compliance Parameters:

• Operating temperature range (-55°C ~ 105°C)
• Material flammability rating (UL94 V-0)
• Series designation (AMPLIMITE HD-20)

Parts meeting all these criteria are classified as direct substitutes. Variations in contact finish thickness, RoHS compliance status, or inventory levels do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the 745053-2 and 5745053-2 are active products from TE Connectivity's AMPLIMITE HD-20 series and meet identical electrical and mechanical specifications for D-Sub connector applications. The connectors are functionally interchangeable in through-hole solder termination designs requiring 25-position, male-pin D-Sub plugs with 6A current capacity at 125V.

The primary distinction between these parts is RoHS compliance status. The 745053-2 is RoHS non-compliant, while the 5745053-2 is RoHS Compliant. Selection between these parts should be based on regulatory requirements applicable to the end application and manufacturing location. Both parts carry identical UL94 V-0 flammability ratings, REACH Affected status, and EAR99 export classification.

Contact finish thickness differs between the parts (745053-2 unspecified versus 5745053-2 Flash), but both maintain gold contact finish specifications suitable for signal transmission in D-Sub applications. Inventory availability shows 876 pieces for 745053-2 and 886 pieces for 5745053-2, indicating both parts are readily available.

Frequently Asked Questions (FAQ)

Q: Can the 5745053-2 be used as a direct replacement for the 745053-2 in existing designs?

A: Yes. Both connectors share identical electrical ratings (6A, 125V), mechanical dimensions (25-position, 2-row, shell size 3), mounting type (through-hole solder), and operating temperature range (-55°C to 105°C). They are functionally interchangeable in D-Sub plug applications.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 745053-2 is RoHS non-compliant, while the 5745053-2 is RoHS Compliant. Contact finish thickness also differs (745053-2 unspecified, 5745053-2 Flash). All other electrical, mechanical, and environmental specifications are identical.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. If RoHS compliance is mandatory for your application or market, select the 5745053-2. If RoHS compliance is not required, either part meets the functional specifications. Consult your design requirements and regional compliance standards.

Q: Are these connectors suitable for high-temperature applications?

A: Both connectors operate across the temperature range -55°C to 105°C. This range is suitable for industrial and commercial applications. Verify that your specific application requirements fall within this operating window.

Q: What is the current-carrying capacity of these D-Sub connectors?

A: Both the 745053-2 and 5745053-2 are rated for 6A continuous current at 125V. Ensure your circuit design does not exceed this current specification.

Q: Are these connectors suitable for signal or power applications?

A: These connectors are classified as Signal contact type. They are designed for signal transmission rather than high-power distribution. Verify that your application requirements align with signal-level specifications.

Q: What termination method is used for these connectors?

A: Both connectors use solder termination for through-hole mounting on printed circuit boards. Ensure your PCB design includes appropriate through-hole pad patterns and solder mask openings for 25-position D-Sub plug connectors.

Q: Are these connectors available in different shell sizes?

A: No. Both the 745053-2 and 5745053-2 use shell size 3 (DB, B) with 25 positions in a 2-row configuration. This is the standard D-Sub layout for these part numbers.

Q: What is the contact material and finish specification?

A: Both connectors feature brass contact material with gold finish. The 5745053-2 specifies Flash thickness for the gold finish, while the 745053-2 does not specify thickness. Both provide corrosion resistance and reliable electrical contact suitable for D-Sub applications.
