Substitute Part Grouping Explanation

Substitution for the 3314-1202 is determined by the following critical parameters:

Connector geometry: 14-position, 2-row configuration at 0.100" (2.54mm) pitch
Mounting interface: Through-hole, right-angle orientation
Electrical performance: 1.75A current rating and -55°C ~ 105°C operating temperature range
Mechanical compatibility: Shrouded construction with male pin contacts
Termination method: Solder termination

The substitute parts D3314-5002-AR and N3314-5002RB maintain these core parameters while offering improvements in product status (active vs. obsolete) and regulatory compliance (RoHS compliant).

Engineering Selection Recommendations

D3314-5002-AR is the primary recommended substitute. This part maintains full electrical and mechanical compatibility with the 3314-1202 while offering active product status and RoHS compliance. The transition from 3-wall to 4-wall shrouding provides enhanced mechanical protection. Packaging in trays supports automated assembly processes.

N3314-5002RB serves as an alternative substitute with identical core specifications to D3314-5002-AR. This variant is supplied in bulk packaging and maintains RoHS compliance with active product status. The contact material composition (copper alloy) matches the original 3314-1202, providing direct electrical equivalence.

Both substitute parts eliminate the obsolescence risk associated with the 3314-1202 while meeting current regulatory requirements for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Are D3314-5002-AR and N3314-5002RB fully compatible with the 3314-1202?

A: Both parts maintain the critical compatibility parameters: 14-position, 2-row configuration at 2.54mm pitch, through-hole right-angle mounting, 1.75A current rating, and -55°C ~ 105°C operating temperature. The core electrical and mechanical interfaces are equivalent.

Q: What is the difference between the two substitute parts?

A: D3314-5002-AR is packaged in trays and uses brass contact material. N3314-5002RB is supplied in bulk packaging with copper alloy contacts. Both are RoHS compliant and active products. Selection depends on assembly process requirements and packaging preferences.

Q: Why does the insulation height differ between the original and substitute parts?

A: The substitute parts feature 4-wall shrouding compared to the 3-wall design of the 3314-1202, resulting in a 0.030" (0.77mm) increase in insulation height. This change does not affect electrical performance or standard PCB mounting compatibility.

Q: What is the significance of the fastening type change from Latch Lock to Push-Pull?

A: Both fastening mechanisms provide secure mating and unmating. The push-pull design in the substitute parts offers simplified connector engagement without compromising mechanical reliability or electrical continuity.

Q: Are there any RoHS compliance considerations for the 3314-1202?

A: The original 3314-1202 is RoHS non-compliant. Both substitute parts (D3314-5002-AR and N3314-5002RB) are RoHS compliant, making them suitable for applications requiring regulatory compliance with current environmental standards.
