Engineering Selection Recommendations

All listed substitute parts maintain Active product status and meet or exceed the compliance and certification requirements of the HARTING 09281482903. Selection among substitutes should be based on the following criteria:

Header Configuration (Direct Type Match): The Amphenol ICC 86093487614755ELF provides header-type connector configuration identical to the main part. This option is preferred when connector type consistency is required within the assembly. Current rating of 1.5A is lower than the main part specification of 2A; applications requiring 2A current capacity should verify compatibility with this substitute.

Plug Configuration (TE Connectivity Options): The TE Connectivity parts (2-1393659-6, 3-1393659-9, 5650479-5, 5650918-5) provide plug-type connector configuration. These are suitable for applications where plug connectors are functionally equivalent to headers. The TE 5650918-5 offers press-fit termination as an alternative to solder termination, providing assembly flexibility. All TE Connectivity parts are ROHS3 compliant and maintain the required operating temperature range.

Packaging and Inventory Considerations: All substitute parts are available in Active status with adequate inventory. TE Connectivity 3-1393659-9 offers the highest inventory level (1353 pcs), followed by TE 5650479-5 (1404 pcs) and Amphenol 86093487614755ELF (1339 pcs).

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity plug connectors replace the HARTING header connector? A: Yes. In backplane connector applications, plug and header configurations are functionally interchangeable when all other parameters (position count, pitch, row configuration, mounting type, and operating temperature) are identical. The TE Connectivity plug parts meet all these requirements.

Q: What is the difference between Style 2R and Style R/2 (1/2 R)? A: Both designations represent equivalent DIN 41612 backplane connector configurations with 3 rows and 48 positions at 0.100" pitch. The style designation reflects different standardization references but provides identical electrical and mechanical compatibility.

Q: Does the Amphenol 86093487614755ELF meet the 2A current rating requirement? A: The Amphenol part is rated at 1.5A, which is lower than the main part specification of 2A. Applications requiring 2A current capacity should verify that 1.5A is acceptable for their specific circuit requirements before substitution.

Q: What is the difference between solder and press-fit termination? A: Both are through-hole termination methods. Solder termination requires manual or automated soldering during assembly. Press-fit termination uses mechanical insertion without soldering. The TE 5650918-5 offers press-fit termination as an alternative assembly approach.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts are RoHS compliant. The HARTING main part and most substitutes are ROHS3 compliant. The TE 5650918-5 and Amphenol 86093487614755ELF are RoHS compliant. All meet regulatory requirements for lead-free and restricted substance compliance.

Q: Can I mix header and plug connectors in the same assembly? A: Yes, provided the mating connector is appropriately configured. Header connectors mate with plug connectors. Verify that your PCB layout and connector mounting positions accommodate the selected connector type.

Q: What is the moisture sensitivity level, and why is it important? A: All parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture-controlled storage or handling procedures.
