Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of core electrical and mechanical parameters. The following parameters establish substitution validity:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (14)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact shape (Square)
• Material flammability rating (UL94 V-0)

The substitute parts N3314-6302RB and N3314-6303RB from 3M satisfy all critical matching parameters. Both parts are manufactured by 3M under the 3000 series and maintain identical positional, pitch, and shrouding specifications. Both substitutes feature latch lock/eject hook fastening with extended length variants and maintain UL94 V-0 flammability compliance.

Parameter Comparison

Engineering Selection Recommendations

Both N3314-6302RB and N3314-6303RB from 3M are active products with full compliance certifications. The 3M substitutes maintain all critical electrical and mechanical parameters required for rectangular connector header applications with 14 positions at 2.54mm pitch.

N3314-6302RB Selection Criteria: This substitute features a contact post length of 0.112" (2.84mm), providing minimal deviation from the original 5111374-2 specification of 0.110" (2.79mm). The overall contact length of 0.652" (16.56mm) accommodates standard through-hole PCB applications. This variant is suitable for applications where post length consistency with the original design is prioritized. Current inventory of 9191 pieces supports high-volume procurement.

N3314-6303RB Selection Criteria: This substitute features an extended contact post length of 0.155" (3.94mm) with an overall contact length of 0.695" (17.65mm). The extended post length accommodates thicker PCB assemblies or applications requiring deeper solder engagement. This variant is suitable for applications with specific PCB thickness requirements or where extended post length provides design advantages. Current inventory of 1552 pieces supports standard procurement volumes.

Both 3M substitutes are RoHS Compliant and REACH Unaffected, providing regulatory compliance advantages over the original part. Both maintain UL94 V-0 flammability ratings and unlimited moisture sensitivity levels. The 3M substitutes support higher current ratings of 1.75A per contact compared to the original 1A specification, providing additional design margin for power delivery applications.

The operating temperature range for 3M substitutes extends to -55°C minimum, compared to the original -65°C specification. Applications requiring operation below -55°C require the original TE Connectivity 5111374-2 part.

Frequently Asked Questions (FAQ)

Q: Can N3314-6302RB and N3314-6303RB be used interchangeably with 5111374-2?

A: Both 3M parts satisfy the critical electrical and mechanical parameters for rectangular connector header substitution. The primary difference between the two 3M variants is contact post length. N3314-6302RB provides minimal post length deviation (0.112" vs. 0.110"), while N3314-6303RB offers extended post length (0.155"). Selection depends on PCB thickness and solder engagement requirements for your specific application.

Q: What is the difference between the two 3M substitute parts?

A: N3314-6302RB and N3314-6303RB differ only in contact post length. N3314-6302RB has a post length of 0.112" (2.84mm) with overall contact length of 0.652" (16.56mm). N3314-6303RB has a post length of 0.155" (3.94mm) with overall contact length of 0.695" (17.65mm). Both maintain identical mating contact length, pitch, position count, and shrouding specifications.

Q: Are there temperature range limitations with the 3M substitutes?

A: The 3M substitutes N3314-6302RB and N3314-6303RB operate across -55°C to 105°C. The original TE Connectivity 5111374-2 operates across -65°C to 105°C. Applications requiring operation below -55°C require the original part.

Q: What are the current rating differences?

A: The original 5111374-2 supports 1A per contact. Both 3M substitutes support 1.75A per contact. The higher current rating of the 3M parts provides additional design margin for power delivery applications without exceeding contact current limits.

Q: Do the 3M substitutes have different packaging?

A: The original 5111374-2 is supplied in Tray packaging. Both 3M substitutes N3314-6302RB and N3314-6303RB are supplied in Bulk packaging. Packaging differences do not affect electrical or mechanical compatibility but may impact handling and storage procedures.

Q: What is the significance of the insulation color difference?

A: The original 5111374-2 features red insulation, while both 3M substitutes feature black insulation. Insulation color is a visual identification characteristic and does not affect electrical performance or mechanical compatibility.

Q: Are the 3M substitutes RoHS compliant?

A: Yes. Both N3314-6302RB and N3314-6303RB are RoHS Compliant. The original 5111374-2 has RoHS Status listed as Not applicable. The RoHS compliance of the 3M substitutes provides regulatory advantages for applications subject to RoHS requirements.

Q: Which substitute should I select for standard PCB thickness applications?

A: N3314-6302RB is recommended for standard PCB thickness applications. The contact post length of 0.112" (2.84mm) provides minimal deviation from the original specification of 0.110" (2.79mm), ensuring compatibility with designs validated for the original part.

Q: Which substitute should I select for thicker PCB assemblies?

A: N3314-6303RB is recommended for thicker PCB assemblies or applications requiring deeper solder engagement. The extended contact post length of 0.155" (3.94mm) accommodates increased PCB thickness while maintaining proper solder joint formation.

Q: What is the inventory status for each substitute?

A: N3314-6302RB has 9191 pieces in stock, supporting high-volume procurement. N3314-6303RB has 1552 pieces in stock, supporting standard procurement volumes. The original 5111374-2 has 741 pieces in stock.
