Engineering Selection Recommendations

NPPC052KFMS-RC (Gold Plated Mating Contacts): This substitute is recommended for applications requiring gold contact finish compatibility with the original 68046-305. The part is in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The lower voltage rating (250V vs. 1000V) and narrower operating temperature range (-40°C to 125°C vs. -65°C to 125°C) must be evaluated against specific application requirements.

NPTC052KFMS-RC (Tin Plated Mating Contacts): This substitute provides an alternative with tin contact finish. It maintains the same mechanical interface and is also in active production with ROHS3 compliance. The same voltage and temperature considerations apply as with the gold-plated variant.

Both substitutes are actively manufactured and stocked, providing superior long-term component availability compared to the obsolete 68046-305. Selection between the two should be based on contact finish requirements and application-specific electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can NPPC052KFMS-RC and NPTC052KFMS-RC be used interchangeably with the 68046-305?

A: Both substitutes maintain the same mechanical interface (10 positions, 0.100" pitch, 2-row configuration, surface mount, push-pull fastening). The primary differences are connector type designation (header vs. receptacle), contact finish (gold or tin vs. gold), voltage rating (250V vs. 1000V), and operating temperature range (-40°C to 125°C vs. -65°C to 125°C). Interchangeability depends on whether your application requirements fall within these substitute specifications.

Q: What is the difference between NPPC052KFMS-RC and NPTC052KFMS-RC?

A: The primary difference is the mating contact finish. NPPC052KFMS-RC features gold-plated mating contacts, while NPTC052KFMS-RC features tin-plated mating contacts. Both maintain identical mechanical dimensions, pitch, row configuration, and electrical ratings. Selection should be based on contact finish compatibility requirements for your specific application.

Q: Why is the voltage rating lower on the substitute parts?

A: The substitute parts are rated at 250V, compared to the original 68046-305 at 1000V. This difference reflects the design specifications of the Sullins connector series. Applications requiring voltages above 250V must use the original part or identify alternative substitutes with higher voltage ratings.

Q: Are the substitute parts RoHS compliant?

A: Yes, both NPPC052KFMS-RC and NPTC052KFMS-RC are ROHS3 compliant. The original 68046-305 is RoHS non-compliant. This compliance difference may be advantageous for new designs or applications with RoHS requirements.

Q: What is the operating temperature range difference?

A: The original 68046-305 operates from -65°C to 125°C, while both substitutes operate from -40°C to 125°C. Applications requiring operation below -40°C must use the original part or identify alternative substitutes with extended low-temperature ratings.

Q: Are the insulation materials compatible?

A: The original part uses Polyphenylene Sulfide (PPS) glass-filled insulation, while the substitutes use Polyamide (PA6T) Nylon 6T insulation. Both materials meet UL94 V-0 flammability requirements. Material selection should be evaluated based on application-specific environmental and chemical exposure conditions.
