• Termination method: Solder Cup
• Dielectric material: Polybutylene Terephthalate (PBT)
• Material flammability rating: UL94 V-0
• Contact finish: Gold

Secondary Compatibility Considerations:

• Current rating: Substitute parts must meet or exceed 3A
• Voltage rating: Substitute parts must meet or exceed 250V
• Operating temperature range: Substitute parts must encompass or exceed -55°C to 105°C
• Shell material and finish: Steel with tin or nickel plating acceptable
• Contact finish thickness: Flash or 8.00µin acceptable

Mounting Type Variation: The 747909-2 specifies free-hanging (in-line) mounting. Substitute parts with panel mount configurations represent functional alternatives for applications where mounting methodology can be adapted to the installation environment.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 5-747909-2

The 5-747909-2 is the direct equivalent of the 747909-2. Both parts share identical electrical and mechanical specifications, including connector type, position count, shell size, termination method, and operating parameters. The 5-747909-2 carries active product status and ROHS3 compliance, addressing the obsolescence of the original part. Inventory availability of 270,265 units supports sustained production and maintenance requirements. This part is the preferred substitute for direct replacement applications.

Secondary Recommendation: 172-E15-203R001

The 172-E15-203R001 from NorComp Inc. provides functional equivalence with the following considerations:

• Meets all core D-Sub receptacle specifications: 15 positions, 2 rows, shell size 2 (DA, A), solder cup termination, gold-plated contacts, UL94 V-0 rating
• Current rating of 5A exceeds the 3A requirement of the 747909-2
• Operating temperature range of -50°C to 100°C encompasses the primary operating envelope, with reduced low-temperature capability (-50°C versus -55°C)
• Active product status and ROHS3 compliance ensure long-term availability and regulatory alignment
• Panel mount configuration requires mechanical adaptation from the free-hanging mounting of the original part
• Inventory of 2,208 units supports availability

Tertiary Consideration: 171-015-203L001

The 171-015-203L001 from NorComp Inc. provides functional equivalence with the following considerations:

• Meets all core D-Sub receptacle specifications: 15 positions, 2 rows, shell size 2 (DA, A), solder cup termination, gold-plated contacts, UL94 V-0 rating
• Current rating of 5A exceeds the 3A requirement
• Operating temperature range of -50°C to 100°C encompasses the primary operating envelope
• Active product status and ROHS3 compliance ensure long-term availability
• Panel mount configuration requires mechanical adaptation
• Inventory of 3,745 units supports availability

Not Recommended: 628-015-222-041

The 628-015-222-041 from Mercury United Electronics lacks sufficient parameter specification to establish complete electrical and mechanical equivalence. Critical parameters including current rating, voltage rating, operating temperature range, and contact finish specifications are not provided. This part cannot be selected without additional technical documentation.

Not Recommended: 172-E15-202R011 and 172-E15-202R021

Both parts carry obsolete product status, which does not address the primary objective of sourcing active alternatives to the discontinued 747909-2. While these parts meet core specifications, their obsolescence status limits their utility for sustained production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-747909-2 be used as a direct replacement for the 747909-2?

A: Yes. The 5-747909-2 is electrically and mechanically identical to the 747909-2. Both parts share the same connector specifications, electrical ratings, and operating parameters. The primary difference is packaging format (tray versus bulk) and product status (active versus obsolete). The 5-747909-2 is the recommended direct substitute.

Q: What is the difference between the 747909-2 and the NorComp alternatives?

A: The 747909-2 is a free-hanging (in-line) connector manufactured by TE Connectivity. The NorComp alternatives (172-E15-203R001 and 171-015-203L001) are panel mount connectors. Both mounting types use identical D-Sub receptacle specifications and solder cup termination. The mounting type difference requires mechanical adaptation to the installation environment. NorComp parts also provide higher current ratings (5A versus 3A) and active product status.

Q: Are the NorComp panel mount connectors compatible with applications designed for the free-hanging 747909-2?

A: Electrical compatibility is established through identical D-Sub specifications, position count, shell size, and contact configuration. Mechanical compatibility depends on the installation environment. Applications with fixed mounting points designed for free-hanging connectors require mechanical redesign to accommodate panel mount flanges. Solder cup termination is identical across all parts, supporting wire attachment compatibility.

Q: What is the significance of the operating temperature range difference between the 747909-2 and NorComp alternatives?

A: The 747909-2 operates from -55°C to 105°C. NorComp alternatives operate from -50°C to 100°C. The NorComp parts provide a 5°C reduction in low-temperature capability and a 5°C reduction in high-temperature capability. For applications operating within the -50°C to 100°C envelope, this difference is not significant. Applications requiring operation below -50°C or above 100°C must retain the 747909-2 or 5-747909-2.

Q: Why is RoHS compliance important for selecting a substitute?

A: The 747909-2 is RoHS non-compliant. The 5-747909-2 and all NorComp alternatives are ROHS3 compliant. RoHS compliance is a regulatory requirement in many markets and is often specified in procurement standards. Selecting ROHS3 compliant alternatives ensures alignment with current environmental regulations and procurement policies.

Q: Can the 628-015-222-041 be used as a substitute?

A: The 628-015-222-041 cannot be recommended without complete technical specifications. Critical parameters including current rating, voltage rating, operating temperature range, and detailed contact specifications are not provided. Substitution decisions require full parameter alignment. Additional technical documentation from Mercury United Electronics is necessary to establish equivalence.

Q: What is the difference between tin-plated and nickel-plated shell finishes?

A: The 747909-2 features a tin-plated steel shell. Some NorComp alternatives feature nickel-plated steel shells. Both finishes provide corrosion resistance and electrical conductivity. Tin plating is generally preferred for solder cup applications due to superior wetting characteristics. Nickel plating provides enhanced corrosion resistance in harsh environments. For standard applications, both finishes are functionally equivalent.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. The 5-747909-2 has 270,265 units in stock, providing substantial availability. The 172-E15-203R001 has 2,208 units, and the 171-015-203L001 has 3,745 units. For high-volume production requirements, the 5-747909-2 offers superior inventory support. For lower-volume applications, NorComp alternatives provide adequate stock levels.

Q: What does "solder cup termination" mean?

A: Solder cup termination refers to a hollow cylindrical contact designed for wire insertion and solder attachment. Wires are inserted into the cup and secured through solder reflow. All substitute parts listed use identical solder cup termination, ensuring compatibility with existing wire attachment processes and equipment.
