Engineering Selection Recommendations

The 3M 3314-5202-UG is obsolete and no longer in active production. Direct replacement with active-status equivalents is necessary for new designs and ongoing supply chain management.

3M Series Substitutes (D3314-5002-AR, N3314-5002RB): Both maintain the original 3M product line with identical core mechanical and electrical specifications. D3314-5002-AR is RoHS Compliant and supplied in Tray packaging. N3314-5002RB is RoHS Compliant and supplied in Bulk packaging. These options preserve design continuity within the 3M connector ecosystem.

TE Connectivity Substitutes (499345-2, 499913-2, 5499345-2): All three TE Connectivity AMP-Latch series connectors provide functional equivalence with extended operating temperature range (-65°C vs. -55°C). The 5499345-2 offers ROHS3 Compliance and represents the most current regulatory alignment. The 499345-2 and 499913-2 are non-compliant or not applicable for RoHS, suitable for legacy applications where RoHS compliance is not required.

Regulatory Compliance Consideration: Applications requiring RoHS compliance should prioritize D3314-5002-AR, N3314-5002RB, or 5499345-2. Applications without RoHS requirements may use any listed substitute based on availability and packaging preference.

Frequently Asked Questions (FAQ)

Q: Can the 3314-5202-UG be directly replaced with any of the listed substitutes?

A: Yes. All listed substitutes maintain identical connector type, contact configuration, pitch, mounting style, and shrouding. Physical and electrical interchangeability is confirmed across all substitute parts.

Q: What is the difference between the 3M and TE Connectivity substitutes?

A: Both manufacturers provide functionally equivalent 14-position, 2.54mm pitch right-angle headers. The primary differences are manufacturer series designation (3M 3000/D3000 vs. TE Connectivity AMP-Latch), contact material composition (Copper Alloy vs. Brass), and regulatory compliance status. TE Connectivity substitutes offer extended operating temperature range to -65°C.

Q: Does packaging type affect electrical performance?

A: No. Packaging (Tray vs. Bulk) is a logistics and handling consideration only. Electrical and mechanical performance is identical regardless of packaging format.

Q: Which substitute should I select for new designs?

A: For new designs requiring regulatory compliance, select D3314-5002-AR, N3314-5002RB, or 5499345-2. For legacy system maintenance, any substitute maintains functional compatibility. Verify availability and lead time with your component supplier.

Q: Are there any mechanical dimension differences between substitutes?

A: Contact length post and insulation height show minor variations. 3M substitutes maintain 0.112" (2.84mm) post length and 0.340" (8.64mm) insulation height. TE Connectivity substitutes specify 0.110" (2.79mm) post length and 0.315" (8.00mm) insulation height. These variations remain within standard connector tolerance ranges and do not affect board-level compatibility.

Q: What is the current rating difference between 3M and TE Connectivity options?

A: The 3314-5202-UG and 3M substitutes are rated at 1.75A. TE Connectivity substitutes are rated at 1A per contact. For applications requiring the full 1.75A rating, 3M substitutes are the appropriate selection.
