6983R10KBLF Equivalent & Substitute Parts

Part Overview

The 6983R10KBLF is an 8-resistor network array manufactured by TT Electronics/BI, featuring 10kΩ isolated resistors in a 16-DIP through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part delivers 100mW power per element with ±0.1% tolerance and ±25ppm/°C temperature coefficient, suitable for precision analog circuits requiring matched resistor networks.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6983R10KBLF is determined by the following mandatory parameters:

• Resistance Value: Must be 10kΩ
• Number of Resistors: Must be 8
• Circuit Type: Must be Isolated
• Package Type: Must be 16-DIP (0.300", 7.62mm)
• Mounting Type: Must be Through Hole
• Operating Temperature Range: Must support -55°C to 125°C

The identified substitute parts meet these core requirements. Variations in tolerance, temperature coefficient, and power per element are permitted within the electrical and mechanical constraints of this product category. All substitute parts maintain the same pin count (16) and physical footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

4116R-1-103 (Bourns Inc.): This part is active and available with higher power dissipation (250mW per element). The tolerance relaxes to ±2% and temperature coefficient increases to ±100ppm/°C. Selection is appropriate for applications where the original ±0.1% tolerance and ±25ppm/°C temperature coefficient are not critical requirements. RoHS non-compliance status must be evaluated against project requirements.

MDP160310K0FE04 (Vishay Dale): This part is active and ROHS3 compliant, offering ±1% tolerance with 250mW power per element. The temperature coefficient is ±100ppm/°C. This substitute provides improved compliance status while maintaining tighter tolerance than the Bourns alternative. Selection is suitable for applications requiring RoHS3 compliance and moderate tolerance specifications.

Both substitutes are electrically and mechanically compatible with the 6983R10KBLF footprint and pin configuration. Selection between them depends on tolerance requirements, compliance mandates, and power dissipation needs of the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 4116R-1-103 or MDP160310K0FE04 be used as direct replacements for the 6983R10KBLF?

A: Both parts are mechanically and electrically compatible as direct replacements. They share the same 16-DIP package footprint, pin count, and operating temperature range. Functional compatibility depends on whether the application tolerates the relaxed tolerance and increased temperature coefficient specifications of the substitutes.

Q: What is the primary difference between the two substitute options?

A: The MDP160310K0FE04 offers ±1% tolerance compared to the 4116R-1-103's ±2% tolerance, and includes ROHS3 compliance. The 4116R-1-103 is RoHS non-compliant. Both provide 250mW power per element versus the original 100mW specification.

Q: Are there any package dimension differences between these parts?

A: All three parts use the 16-DIP (0.300", 7.62mm) package. Minor variations exist in overall length and height: the 6983R10KBLF measures 0.750" L × 0.250" W with 0.170" maximum seated height; the 4116R-1-103 measures 0.865" L × 0.300" W with 0.185" maximum seated height; the MDP160310K0FE04 measures 0.850" L × 0.250" W with 0.155" maximum seated height. These variations remain within standard DIP package tolerances and do not affect PCB footprint compatibility.

Q: Which substitute is recommended for new designs?

A: Selection depends on compliance and tolerance requirements. For RoHS3-compliant applications, the MDP160310K0FE04 is the appropriate choice. For applications where RoHS compliance is not required and cost is a primary factor, the 4116R-1-103 is viable.

Q: How do tolerance and temperature coefficient differences affect circuit performance?

A: The original 6983R10KBLF provides ±0.1% tolerance and ±25ppm/°C temperature coefficient. The substitutes offer relaxed specifications: 4116R-1-103 at ±2% tolerance and ±100ppm/°C, and MDP160310K0FE04 at ±1% tolerance and ±100ppm/°C. Applications requiring precision matching or stable performance across temperature extremes must evaluate whether these relaxed specifications remain acceptable.
