• Number of rows: 2
• Shell size and layout: 2 (DA, A)
• Mounting type: Free Hanging (In-Line)
• Termination type: IDC, Discrete Wire
• Shell material and finish: Steel, Tin Plated
• Contact finish: Gold at 30.0µin (0.76µm) thickness
• Voltage rating: 250V
• Operating temperature range: -55°C ~ 105°C
• Material flammability rating: UL94 V-0
• Contact material: Phosphor Bronze
• Dielectric material: Thermoplastic, Glass Filled
• Color: Black
• MSL rating: 1 (Unlimited)
• Series: AMPLIMITE HDE-20

The substitute part 1-745493-4 meets all these requirements and is classified as active, providing a direct replacement for the obsolete 745493-2.

Parameter Comparison

Engineering Selection Recommendations

The 1-745493-4 is the direct equivalent substitute for the obsolete 745493-2. Both parts are manufactured by TE Connectivity and belong to the AMPLIMITE HDE-20 series. All electrical and mechanical specifications are identical, ensuring complete functional compatibility.

Key Selection Factors:

Product Status: The 745493-2 is obsolete, while 1-745493-4 is active. Selection of the active part ensures continued availability and supply chain stability.

Regulatory Compliance: The 1-745493-4 offers improved compliance status. It is ROHS3 compliant and REACH unaffected, compared to the 745493-2, which is RoHS non-compliant with vendor-undefined REACH status. For applications subject to environmental regulations, the 1-745493-4 is the appropriate choice.

Packaging: The 1-745493-4 is supplied in bulk packaging, whereas the 745493-2 packaging is unspecified. This distinction affects procurement logistics but does not impact electrical or mechanical performance.

Inventory Availability: Both parts maintain substantial stock levels (745493-2: 835 pcs; 1-745493-4: 824 pcs), supporting immediate procurement requirements.

For new designs, system upgrades, or replacement procurement, the 1-745493-4 is the specified equivalent part.

Frequently Asked Questions (FAQ)

Q: Can the 1-745493-4 be used as a direct replacement for the 745493-2 in existing applications?

A: Yes. The 1-745493-4 is a direct equivalent substitute. All electrical and mechanical parameters are identical, including connector type, pin count, shell size, termination method, voltage rating, temperature range, and material specifications. No design modifications are required.

Q: What is the difference between the 745493-2 and 1-745493-4?

A: The primary differences are product status and regulatory compliance. The 745493-2 is obsolete and RoHS non-compliant, while the 1-745493-4 is active and ROHS3 compliant. The 1-745493-4 also has defined REACH status (REACH Unaffected) compared to the 745493-2 (Vendor Undefined). Functionally and mechanically, both parts are identical.

Q: Are there any compatibility concerns when substituting the 1-745493-4 for the 745493-2?

A: No compatibility concerns exist. Both connectors are D-Sub receptacles with 15 positions, 2 rows, shell size 2 (DA, A), and identical termination specifications (IDC, Discrete Wire). They are mechanically and electrically interchangeable.

Q: What packaging options are available for these parts?

A: The 745493-2 packaging is unspecified in available documentation. The 1-745493-4 is supplied in bulk packaging. For specific packaging requirements, contact the manufacturer or authorized distributor.

Q: Are both parts suitable for the same operating temperature and voltage conditions?

A: Yes. Both the 745493-2 and 1-745493-4 operate across the identical temperature range of -55°C to 105°C and are rated for 250V. They are suitable for the same environmental and electrical conditions.

Q: What is the wire gauge specification for these connectors?

A: The 1-745493-4 supports wire gauges 22-26 AWG. The 745493-2 wire gauge specification is not provided in available documentation. For applications requiring specific wire gauge compatibility, the 1-745493-4 specification (22-26 AWG) applies to the substitute part.

Q: Why is RoHS compliance important for this connector?

A: RoHS compliance indicates the connector meets restrictions on hazardous substances in electrical and electronic equipment. The 1-745493-4 is ROHS3 compliant, making it suitable for applications and markets with environmental regulatory requirements. The obsolete 745493-2 is RoHS non-compliant and may not meet current procurement standards in regulated industries.

Q: Can I use the 745493-2 if the 1-745493-4 is unavailable?

A: The 745493-2 is functionally equivalent and remains in stock (835 pcs available). However, the obsolete status and non-compliant regulatory status of the 745493-2 make the active, compliant 1-745493-4 the preferred choice for new procurement and long-term system reliability.
