Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 745057-3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 5745057-3 qualifies as a direct equivalent based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Connector type: Receptacle, Female Sockets
• Number of positions: 15
• Number of rows: 2
• Current rating: 6A
• Voltage rating: 125V
• Operating temperature range: -55°C ~ 105°C
• Contact finish: Gold (Flash)
• Contact material: Phosphor Bronze

Mechanical Parameters (Must Match Exactly):

• Connector style: D-Sub
• Shell size and layout: 2 (DA, A)
• Mounting type: Through Hole
• Termination method: Solder
• Flange feature: Housing/Shell (4-40)
• Dielectric material: Polyester
• Material flammability rating: UL94 V-0
• Series: AMPLIMITE HD-20
• Packaging: Tube

Both parts maintain identical form, fit, and function characteristics. The primary distinction between 745057-3 and 5745057-3 relates to regulatory compliance status, which does not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 745057-3 and 5745057-3 are electrically and mechanically equivalent D-Sub receptacle connectors. Selection between these two part numbers is determined by regulatory compliance requirements rather than functional performance.

745057-3 Selection Criteria:

• Applications where RoHS non-compliance is acceptable or required
• Legacy system designs with established compliance documentation
• Procurement scenarios where RoHS compliance is not a contractual requirement

5745057-3 Selection Criteria:

• Applications requiring RoHS compliance certification
• New product designs subject to RoHS Directive 2011/65/EU
• Procurement specifications mandating RoHS-compliant components
• Supply chain requirements for REACH-affected materials with RoHS compliance

Both parts maintain identical electrical performance (6A current rating, 125V voltage rating, -55°C to 105°C operating range), mechanical form factor (15-position D-Sub, 2-row configuration, through-hole solder termination), and material specifications (UL94 V-0 flammability rating, phosphor bronze contacts with gold flash finish, polyester dielectric). Both are active products with current inventory availability and identical packaging in tube format.

Frequently Asked Questions (FAQ)

Q: Are 745057-3 and 5745057-3 pin-for-pin compatible?

A: Yes. Both connectors are 15-position D-Sub receptacles with identical pin configurations, spacing, and contact arrangements. They share the same shell size (2/DA, A), mounting footprint, and solder pad layout for through-hole PCB assembly.

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

A: The primary difference is RoHS compliance status. The 5745057-3 is RoHS compliant, while the 745057-3 is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I substitute 5745057-3 for 745057-3 in an existing design?

A: Yes. The 5745057-3 is a direct substitute with identical electrical performance, mechanical dimensions, and contact specifications. No design modifications are required.

Q: Do these connectors have different current or voltage ratings?

A: No. Both connectors are rated for 6A continuous current and 125V maximum voltage. Operating temperature range is -55°C to 105°C for both parts.

Q: Are the contact materials the same?

A: Yes. Both connectors use phosphor bronze contacts with gold flash finish. Contact finish thickness and material composition are identical.

Q: What is the difference in packaging between these parts?

A: Both parts are supplied in tube packaging. There is no packaging difference.

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

A: Specify 5745057-3 if your design or procurement requirements mandate RoHS compliance. Specify 745057-3 only if RoHS non-compliance is explicitly required or if legacy documentation specifies this part number.

Q: Are both parts currently in production?

A: Yes. Both 745057-3 and 5745057-3 are active products with current inventory availability from TE Connectivity AMP Connectors.

Q: Do these connectors meet UL standards?

A: Yes. Both connectors carry a UL94 V-0 material flammability rating, indicating compliance with UL94 vertical flame test requirements.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
