Engineering Selection Recommendations

For RoHS-Compliant Applications: Select from D3314-5002-AR, N3314-5002RB, 09185146913001, 09195146913, 2-5499141-2, or 2-5499376-2. These parts carry active product status and meet RoHS compliance requirements (RoHS Compliant or ROHS3 Compliant).

For Legacy or Non-Regulated Applications: 499141-2, 499345-2, and 499786-2 remain functionally equivalent but carry non-compliant or not-applicable RoHS status. These are suitable only where RoHS compliance is not mandated.

For Extended Temperature Range: HARTING parts 09185146913001 and 09195146913 support -55°C ~ 125°C, exceeding the original -55°C ~ 105°C specification. TE Connectivity AMP-Latch series (2-5499141-2, 2-5499376-2, 499141-2, 499345-2, 499786-2) support -65°C ~ 105°C, providing lower temperature margin.

For Current Rating Consistency: D3314-5002-AR and N3314-5002RB maintain the 1.75A rating. TE Connectivity parts specify 1A per contact, which is lower than the original specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 3314-5302UG with a part having different position count? A: No. The 14-position configuration is a core parameter. Part 09185167904800, while from the same manufacturer family, has 16 positions and vertical mounting, making it incompatible.

Q: What is the difference between fastening types (Latch Lock/Eject Hooks, Long vs. Short)? A: Fastening type affects mating force and mechanical retention but does not prevent electrical substitution. Long hooks provide stronger retention; short hooks reduce mating force. Both are acceptable substitutes provided all other parameters align.

Q: Are HARTING parts 09185146913001 and 09195146913 direct substitutes? A: Yes, both are direct substitutes. The primary difference is contact length mating (0.228" vs. 0.240") and insulation color (Black vs. Beige), which do not affect electrical or mechanical compatibility in standard applications.

Q: Why do TE Connectivity parts specify 1A per contact instead of 1.75A? A: Current rating differences reflect design variations between manufacturers. TE Connectivity AMP-Latch series is rated at 1A per contact. For applications requiring 1.75A, verify that the circuit design accommodates the lower rating or select 3M alternatives (D3314-5002-AR or N3314-5002RB).

Q: What packaging options are available? A: Substitute parts are available in Tray (D3314-5002-AR, 2-5499141-2, 2-5499376-2) and Bulk (N3314-5002RB, 09185146913001, 09195146913, 499141-2, 499345-2, 499786-2) configurations. Select based on procurement and inventory requirements.

Q: Is the 3314-5302UG RoHS compliant? A: No. The 3314-5302UG is RoHS non-compliant. For RoHS-regulated applications, substitute with D3314-5002-AR, N3314-5002RB, 09185146913001, 09195146913, 2-5499141-2, or 2-5499376-2.

Q: Can I use 499345-2 or 499786-2 in new designs? A: These parts are functionally equivalent but carry RoHS non-compliant or not-applicable status. Use only in legacy designs or non-regulated applications. For new designs, select RoHS-compliant alternatives.
