RN65C1001DBSL Equivalent & Substitute Parts

Part Overview

The RN65C1001DBSL is a 1 kOhms ±0.5% metal film through-hole resistor rated at 0.5W (1/2W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN65 series (MIL-R-10509/2), this component features flame retardant coating, moisture resistance, and safety certification suitable for military and high-reliability applications. The part is currently active in production with 1090 units in stock. Substitute parts may be required due to inventory constraints, design upgrades for improved tolerance specifications, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65C1001DBSL is determined by the following critical parameters:

• Resistance Value: Must be 1 kOhms
• Power Rating: Must be 0.5W (1/2W) minimum
• Package Configuration: Must be Axial
• Composition: Must be Metal Film
• Series Compliance: Must belong to RN65 military series (MIL-R-10509/2)
• Operating Temperature Range: Must support -65°C to 175°C
• Temperature Coefficient: Must be ±50ppm/°C
• Physical Dimensions: Must match 0.180" Dia × 0.562" L (4.57mm × 14.27mm)

The RN65C1001BB14 qualifies as a direct substitute because it maintains all critical parameters while offering improved tolerance specification (±0.1% versus ±0.5%). This represents an upgrade path within the same military-grade product family.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65C1001DBSL and RN65C1001BB14 are active production components manufactured by Vishay Dale within the military-grade RN65 series. Selection between these parts should be based on tolerance requirements:

• RN65C1001DBSL is appropriate for applications where ±0.5% tolerance meets circuit specifications and cost optimization is a priority.
• RN65C1001BB14 is suitable for applications requiring tighter tolerance control (±0.1%) within the same military-grade platform, offering improved accuracy without changing package, thermal, or compliance characteristics.

Both parts maintain identical RoHS non-compliant and REACH Affected status, ensuring consistent regulatory treatment in supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can RN65C1001BB14 replace RN65C1001DBSL in existing designs?

A: Yes. The RN65C1001BB14 is a direct substitute with identical electrical and mechanical specifications except for tolerance. The ±0.1% tolerance of the substitute is tighter than the ±0.5% of the original part, making it compatible with any application designed for the RN65C1001DBSL.

Q: Are there physical dimension differences between these parts?

A: No. Both parts share identical axial package dimensions of 0.180" Dia × 0.562" L (4.57mm × 14.27mm), ensuring identical PCB footprint and mounting compatibility.

Q: What is the primary difference between these two resistors?

A: The tolerance specification differs. RN65C1001DBSL offers ±0.5% tolerance, while RN65C1001BB14 provides ±0.1% tolerance. All other electrical characteristics, including resistance value, power rating, temperature coefficient, and operating temperature range, are identical.

Q: Do both parts comply with the same military standards?

A: Yes. Both parts are manufactured to MIL-R-10509/2 specification within the RN65 military series and share identical feature sets including flame retardant coating, moisture resistance, and safety certification.

Q: Are there inventory or lead time considerations for substitution?

A: Current inventory shows 1090 units of RN65C1001DBSL and 812 units of RN65C1001BB14 in stock. Substitution decisions may be influenced by availability and project timeline requirements.
