Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68046-307PLF is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 14
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Contact Material: Phosphor Bronze
• Material Flammability Rating: UL94 V-0

Allowable Variations:

• Connector Type: Receptacle to Header (functional compatibility in board-to-board applications)
• Contact Finish - Mating: Gold or Tin (both provide adequate electrical conductivity)
• Insulation Material: PPS Glass Filled or Polyamide (PA6T) Nylon 6T (both meet flammability requirements)
• Operating Temperature: Minimum -40°C acceptable (subset of -65°C range)
• Voltage Rating: 250V acceptable (subset of 1000V rating)
• Current Rating: 3A specified for substitutes (main part rating not specified)

The identified substitute parts NPPC072KFMS-RC and NPTC072KFMS-RC from Sullins Connector Solutions meet all mandatory parameters and fall within allowable variations.

Parameter Comparison

Engineering Selection Recommendations

Both NPPC072KFMS-RC and NPTC072KFMS-RC are active products with current manufacturing status and full compliance certifications. Selection between these substitutes and the main part depends on application-specific requirements:

68046-307PLF (Amphenol ICC): Select when extended operating temperature range (-65°C minimum) or elevated voltage rating (1000V) is required. Suitable for automotive, industrial, and telecommunications applications requiring higher thermal and electrical stress tolerance.

NPPC072KFMS-RC (Sullins, Gold Finish): Select for applications requiring gold contact finish with standard operating temperature (-40°C to 125°C) and voltage rating (250V). Maintains compatibility with board-to-board mating through header configuration.

NPTC072KFMS-RC (Sullins, Tin Finish): Select for cost-optimized designs where tin contact finish is acceptable and operating conditions remain within -40°C to 125°C and 250V limits. Identical electrical and mechanical specifications to NPPC072KFMS-RC except contact finish material.

All three parts carry UL94 V-0 flammability certification, MSL 1 moisture sensitivity, and RoHS compliance, ensuring suitability for modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can NPPC072KFMS-RC or NPTC072KFMS-RC be used as direct replacements for 68046-307PLF?

A: Both Sullins parts are functionally compatible in board-to-board applications. The primary difference is connector type (Header vs. Receptacle), which requires mating with the opposite connector type. Verify that your mating connector is compatible with a header configuration before substitution.

Q: What is the difference between NPPC072KFMS-RC and NPTC072KFMS-RC?

A: The parts are identical except for contact finish material. NPPC072KFMS-RC features gold-plated mating contacts, while NPTC072KFMS-RC features tin-plated mating contacts. Both provide equivalent electrical performance within the specified voltage and current ratings.

Q: Are there temperature or voltage limitations when using Sullins substitutes?

A: Yes. Sullins parts operate within -40°C to 125°C (versus -65°C to 125°C for the main part) and are rated for 250V (versus 1000V for the main part). Applications requiring extended low-temperature operation below -40°C or voltages exceeding 250V must use the 68046-307PLF.

Q: What packaging differences exist between these parts?

A: The 68046-307PLF is supplied in Tape & Reel (TR) packaging. Both Sullins substitutes are supplied in Tube packaging. Verify that your assembly process accommodates tube packaging or arrange for reeling services if required.

Q: Are all three parts RoHS compliant?

A: Yes. The 68046-307PLF is RoHS Compliant. Both NPPC072KFMS-RC and NPTC072KFMS-RC are ROHS3 Compliant, meeting current regulatory requirements.

Q: What is the significance of the insulation height difference (0.310" vs. 0.299")?

A: The 0.011" (0.27mm) difference in insulation height is within typical manufacturing tolerances for this connector class. This minor variation does not affect functional compatibility in standard board-to-board applications but should be verified if precise stacking height is critical to your design.

Q: Can I mix gold and tin contact finishes in the same connector assembly?

A: No. Maintain consistent contact finish within a single mating pair. Use either NPPC072KFMS-RC (gold) or NPTC072KFMS-RC (tin) throughout the assembly to ensure uniform electrical performance and contact reliability.
