Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 745536-2 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for connector style, position count, row configuration, shell size, mounting orientation, termination method, contact materials, and performance ratings.

The TE Connectivity 5745536-2 qualifies as a direct substitute based on the following matching parameters:

• Connector style: D-Sub receptacle with female sockets
• Position and row configuration: 25 positions, 2 rows
• Shell size and layout: Size 3 (DB, B)
• Mounting type: Through hole, right angle
• Termination method: Solder
• Shell material and finish: Steel, tin plated
• Contact finish: Gold
• Current rating: 6A
• Voltage rating: 125V
• Operating temperature range: -55°C to 105°C
• Flange feature: Mating side, female screwlock (4-40)
• Contact type: Signal
• Material flammability rating: UL94 V-0
• Contact material: Phosphor bronze

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5745536-2 is the direct functional equivalent for the obsolete 745536-2 model. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including position count, shell size, mounting configuration, current and voltage ratings, and operating temperature range.

The 5745536-2 offers two significant advantages over the obsolete 745536-2:

Product Status: The 5745536-2 carries active product status with 5499 units in stock, ensuring long-term availability and continued manufacturer support. The 745536-2 is obsolete with limited remaining inventory of 1022 units.

Regulatory Compliance: The 5745536-2 is RoHS compliant, whereas the 745536-2 is RoHS non-compliant. The 5745536-2 also carries REACH Unaffected status, providing enhanced environmental and regulatory alignment for new designs and system upgrades.

Both connectors are rated for identical electrical performance (6A at 125V), temperature operation (-55°C to 105°C), and mechanical durability (UL94 V-0 flammability rating). The dielectric material differs between the two models (thermoplastic versus polyamide nylon glass-filled), but both maintain equivalent functional performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5745536-2 be used as a direct replacement for the 745536-2 in existing applications?

A: Yes. The 5745536-2 is electrically and mechanically equivalent to the 745536-2 across all specified parameters. Both connectors feature identical 25-position D-Sub receptacle configuration, right-angle through-hole mounting, solder termination, 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. The connectors are interchangeable in applications where these specifications are required.

Q: What is the difference in dielectric material between the two connectors?

A: The 745536-2 uses thermoplastic dielectric material, while the 5745536-2 uses polyamide (PA) nylon with glass filling. Both materials meet the UL94 V-0 flammability rating and maintain equivalent electrical insulation properties within the specified operating parameters. The glass-filled polyamide in the 5745536-2 provides enhanced mechanical stability.

Q: Why should I select the 5745536-2 over the 745536-2?

A: The 5745536-2 is the recommended selection for new designs and system upgrades. It carries active product status with significantly higher inventory availability (5499 units versus 1022 units). The 5745536-2 is RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements. The 745536-2 is obsolete and RoHS non-compliant, making it unsuitable for applications requiring regulatory compliance.

Q: Are there any packaging differences between these connectors?

A: The 745536-2 packaging specification is not provided in the available data. The 5745536-2 is supplied in bulk packaging. Contact the manufacturer for specific packaging requirements or alternative packaging options for either connector.

Q: What is the contact finish thickness specification?

A: The 745536-2 specifies a contact finish thickness of 30.0µin (0.76µm). The 5745536-2 contact finish thickness specification is not provided in the available data. Both connectors feature gold contact finish. For applications requiring specific contact finish thickness verification, consult the manufacturer's detailed technical documentation.

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

A: Yes. Both the 745536-2 and 5745536-2 are rated for operation across the identical temperature range of -55°C to 105°C. Both connectors maintain their electrical and mechanical specifications throughout this operating range.

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

A: Both the 745536-2 and 5745536-2 carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
