6983R100KDLF Equivalent & Substitute Parts

Part Overview

The 6983R100KDLF is an 8-resistor network array manufactured by TT Electronics/BI, featuring 100k Ohm isolated resistors in a 16-DIP through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates across the industrial temperature range of -55°C to 125°C and is suitable for applications requiring precision resistor networks with tight tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 6983R100KDLF is determined by the following critical parameters: 100k Ohm resistance value, 8-resistor isolated configuration, 16-DIP package format, through-hole mounting, and -55°C to 125°C operating temperature range. All identified substitute parts maintain these core electrical and mechanical specifications. Variations in tolerance, power rating, and temperature coefficient are secondary parameters that may affect circuit performance but do not prevent functional substitution within the specified package and pin configuration.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as active products with current manufacturing status, providing supply chain continuity for the obsolete 6983R100KDLF. The 4116R-1-104LF (Bourns) and MDP1603100KFE04 (Vishay Dale) maintain identical package geometry and pin configuration, enabling direct board-level substitution without layout modifications.

The MDP1603100KFE04 offers superior tolerance performance at ±1% compared to the original ±0.5%, with ROHS3 compliance and unlimited moisture sensitivity rating. The 4116R-1-104LF provides increased power dissipation capacity at 250mW per element versus the original 100mW, with ROHS3 compliance and tube packaging.

Both substitutes operate across the full -55°C to 125°C temperature range. Selection between alternatives depends on tolerance requirements, power dissipation needs, and compliance certifications applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 4116R-1-104LF and MDP1603100KFE04 be used interchangeably with the 6983R100KDLF?

A: Both parts maintain the same 100k Ohm resistance, 8-resistor isolated configuration, 16-DIP package format, and through-hole mounting. Direct substitution is possible at the board level without layout changes.

Q: What are the tolerance differences between the main part and substitutes?

A: The 6983R100KDLF specifies ±0.5% tolerance. The 4116R-1-104LF provides ±2% tolerance, while the MDP1603100KFE04 provides ±1% tolerance. Applications requiring the original ±0.5% specification should evaluate whether the substitute tolerance is acceptable for circuit performance.

Q: How do power ratings differ?

A: The 6983R100KDLF is rated at 100mW per element. Both substitutes are rated at 250mW per element, providing increased thermal margin in power-dissipation-limited applications.

Q: Are there physical dimension differences?

A: All three parts use the 16-DIP (0.300", 7.62mm) package. Minor variations exist in overall length and height, but these do not affect PCB footprint compatibility or through-hole mounting.

Q: What compliance certifications apply to the substitute parts?

A: Both the 4116R-1-104LF and MDP1603100KFE04 are ROHS3 compliant. The MDP1603100KFE04 carries unlimited moisture sensitivity rating (MSL 1), while the 4116R-1-104LF is not applicable for MSL classification.

Q: How do temperature coefficients compare?

A: The 6983R100KDLF specifies ±25ppm/°C. Both substitutes specify ±100ppm/°C, representing a four-fold increase in temperature-dependent resistance drift. Applications with strict temperature stability requirements should account for this difference.
