Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3314-6205 is determined by the following critical parameters:

• Connector Configuration: 14-position, 2-row header with 0.100" (2.54mm) pitch and row spacing
• Shrouding Design: 4-wall shrouded construction
• Mounting Method: Through-hole PCB mounting
• Contact System: Male pin contacts with gold mating surface finish
• Environmental Compliance: UL94 V-0 flammability rating and operating temperature range of -55°C to 105°C
• Electrical Performance: 1A minimum current rating

The primary distinction among substitutes involves termination method (wire wrap versus solder), contact post geometry, and product status (active versus obsolete). These variations affect assembly compatibility and long-term availability but do not alter the fundamental mating interface or electrical performance envelope.

Parameter Comparison

Engineering Selection Recommendations

N3314-6002RB is the primary substitute for the obsolete 3314-6205. This part maintains active product status, ensuring long-term availability and supply chain stability. It is RoHS compliant and features improved current rating (1.75A versus 1A), providing enhanced electrical margin. The insulation material upgrade from PBT to PCT offers superior thermal and mechanical performance. The solder termination method is standard in modern PCB assembly processes.

3314-6002 is an alternative substitute that shares identical mating interface geometry and electrical characteristics with the main part. However, this part is also classified as obsolete and carries RoHS non-compliance status, limiting its suitability for new designs or systems requiring regulatory compliance documentation.

For applications requiring wire wrap termination compatibility, the 3314-6205 contact post length (0.610") differs significantly from substitute parts (0.112"), necessitating assembly method redesign. This geometric difference is the primary constraint for direct mechanical substitution.

Frequently Asked Questions (FAQ)

Q: Can N3314-6002RB directly replace 3314-6205 in existing assemblies?

A: The mating interface is identical (14 positions, 2 rows, 0.100" pitch, 4-wall shrouding). However, the contact post length differs: 3314-6205 has 0.610" posts for wire wrap termination, while N3314-6002RB has 0.112" posts for solder termination. PCB layout and assembly method must be evaluated for compatibility.

Q: What is the significance of the insulation material change from PBT to PCT in N3314-6002RB?

A: Polycyclohexylenedimethylene Terephthalate (PCT) provides improved thermal stability and mechanical properties compared to Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and operate across the same temperature range (-55°C to 105°C). This change represents material advancement in the product line.

Q: Why is N3314-6002RB preferred over 3314-6002?

A: N3314-6002RB is active product status with RoHS compliance, while 3314-6002 is obsolete and RoHS non-compliant. For new designs and systems requiring regulatory documentation, N3314-6002RB is the appropriate selection.

Q: Are there electrical performance differences between these parts?

A: N3314-6002RB has a current rating of 1.75A compared to 1A for both 3314-6205 and 3314-6002. All parts maintain identical contact geometry, pitch, and gold mating surface finish. The higher current rating in N3314-6002RB provides additional electrical margin without affecting mating interface compatibility.

Q: What packaging options are available?

A: 3314-6205 is supplied in standard packaging. Both 3314-6002 and N3314-6002RB are available in bulk packaging, which may affect procurement quantities and lead times.
