Key Parameters

Substitute Part Grouping Explanation

The substitute part 1-745492-8 is classified as a direct equivalent to the main part 745492-2 based on the following critical parameters that determine substitution validity:

Matching Parameters (Substitution Basis):

• Connector style, type, and pin configuration (D-Sub plug, 9-position, male pins)
• Shell size and connector layout (Size 1, DE/E configuration)
• Mounting type (free hanging, in-line)
• Termination capability (IDC and discrete wire)
• Shell material and finish (steel, tin plated)
• Contact material and finish (phosphor bronze with gold flash)
• Electrical ratings (250V, UL94 V-0)
• Operating temperature range (-55°C ~ 105°C)
• Dielectric material composition (thermoplastic, glass filled)
• Grounding indent features

Differentiating Factors:

• Product status: 745492-2 is obsolete; 1-745492-8 is active
• RoHS compliance: 745492-2 is non-compliant; 1-745492-8 is ROHS3 compliant
• REACH status: 745492-2 is vendor undefined; 1-745492-8 is REACH unaffected
• Packaging: 745492-2 is unspecified; 1-745492-8 is bulk
• Wire gauge specification: 745492-2 is unspecified; 1-745492-8 supports 22-26 AWG

The substitution is valid for all applications where the main part was previously used, with the added benefit of improved regulatory compliance in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-745492-8 is the direct equivalent for the obsolete TE Connectivity 745492-2 connector. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The main part 745492-2 is classified as obsolete, making the active substitute 1-745492-8 the appropriate choice for ongoing procurement and new designs requiring this connector type.

Regulatory Compliance: The substitute part 1-745492-8 achieves ROHS3 compliance and REACH unaffected status, providing improved regulatory alignment compared to the non-compliant main part. This compliance status is significant for applications subject to environmental and hazardous substance regulations.

Functional Equivalence: All critical electrical, mechanical, and thermal parameters are identical between the two parts. The 9-position D-Sub plug configuration, IDC/discrete wire termination, 250V rating, and -55°C to 105°C operating range are preserved in the substitute part.

Wire Gauge Specification: The substitute part explicitly specifies 22-26 AWG wire gauge compatibility, providing clear guidance for termination practices. This specification aligns with standard IDC connector wire gauge requirements.

Supply Chain Continuity: With 2,157 pieces in stock, the substitute part 1-745492-8 ensures availability for both replacement and new application requirements, whereas the obsolete main part has limited future availability despite current inventory levels.

Frequently Asked Questions (FAQ)

Q: Can the 1-745492-8 substitute directly replace the 745492-2 in existing applications?

A: Yes. The 1-745492-8 is a direct functional equivalent with identical connector style, pin configuration, electrical ratings, and operating parameters. All mechanical and electrical interfaces are compatible.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The main part 745492-2 is RoHS non-compliant, while the substitute 1-745492-8 is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the substitute part is the appropriate selection. For legacy systems without regulatory constraints, both parts are functionally equivalent.

Q: Are there any differences in termination capability between these connectors?

A: No. Both parts support IDC (Insulation Displacement Contact) and discrete wire termination methods. The substitute part specifies 22-26 AWG wire gauge compatibility, which represents standard practice for this connector class.

Q: What is the difference between the packaging specifications?

A: The main part 745492-2 has unspecified packaging, while the substitute 1-745492-8 is supplied in bulk packaging. Bulk packaging is standard for active production parts and does not affect connector performance or compatibility.

Q: Why is the main part classified as obsolete?

A: The 745492-2 is obsolete due to its RoHS non-compliance status and the availability of the compliant substitute 1-745492-8. TE Connectivity has transitioned to the active equivalent part for ongoing production and supply.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts have a 250V voltage rating, UL94 V-0 flammability rating, and identical operating temperature range of -55°C to 105°C. Current rating varies by wire gauge in both cases.

Q: Can I use the 1-745492-8 in new designs?

A: Yes. The 1-745492-8 is the recommended part for new designs. It provides improved regulatory compliance, active product status, and confirmed availability compared to the obsolete main part.

Q: What is the REACH status difference, and does it matter?

A: The main part has vendor-undefined REACH status, while the substitute is REACH unaffected. REACH unaffected status indicates the part does not contain substances of very high concern (SVHC) on the candidate list, providing clearer regulatory standing for the substitute part.
