Substitute Part Grouping Explanation

The RN70C4023BB14 qualifies as a direct substitute for the RN70D4023FRE6 based on the following critical parameters:

• Resistance Value: Both parts are 402 kOhms
• Power Rating: Both rated at 0.75W
• Composition: Both are metal film construction
• Package Type: Both use axial through-hole configuration
• Physical Dimensions: Identical at 0.180" Dia × 0.562" L (4.57mm × 14.27mm)
• Operating Temperature Range: Both operate from -65°C to 175°C
• Series Compliance: Both belong to the military RN70 series per MIL-R-10509/3
• Features: Both include flame retardant coating, military grade, moisture resistance, and safety certification

The primary differences are packaging format (Tape & Reel versus Bulk) and tolerance specification (±1% versus ±0.1%), with the substitute offering improved tolerance performance.

Parameter Comparison

Engineering Selection Recommendations

Both the RN70D4023FRE6 and RN70C4023BB14 are active production components from Vishay Dale with identical military certification and compliance status. Selection between these parts should be based on:

• Packaging Requirements: Choose RN70D4023FRE6 for automated assembly processes requiring tape and reel format; select RN70C4023BB14 for bulk procurement or manual assembly operations.
• Tolerance Specification: The RN70C4023BB14 provides ±0.1% tolerance compared to ±1% for the RN70D4023FRE6, suitable for applications requiring tighter resistance accuracy. The RN70C4023BB14 also features a lower temperature coefficient (±50ppm/°C versus ±100ppm/°C), resulting in improved stability across the operating temperature range.
• Inventory Availability: Both parts are in active stock; selection may depend on supply chain requirements and lead time considerations.

Both parts maintain identical electrical performance in terms of resistance value, power rating, and operating temperature range, ensuring direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RN70C4023BB14 be used as a direct replacement for RN70D4023FRE6?

A: Yes. Both parts share identical resistance value (402 kOhms), power rating (0.75W), physical dimensions, operating temperature range (-65°C to 175°C), and military series certification (MIL-R-10509/3). The primary differences are packaging format and tolerance specification, which do not affect electrical interchangeability in circuit applications.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment, where components are wound on a continuous tape. Bulk packaging is suitable for manual assembly or applications where automated handling is not required. Both formats contain the same component; the choice depends on manufacturing process requirements.

Q: Does the improved tolerance of RN70C4023BB14 affect circuit performance?

A: The RN70C4023BB14 offers ±0.1% tolerance versus ±1% for the RN70D4023FRE6. This tighter tolerance specification results in more precise resistance values and is beneficial for applications requiring high accuracy. The lower temperature coefficient (±50ppm/°C versus ±100ppm/°C) also provides improved stability across temperature variations. Applications with standard tolerance requirements will function identically with either part.

Q: Are both parts compliant with military standards?

A: Yes. Both RN70D4023FRE6 and RN70C4023BB14 are certified to MIL-R-10509/3 military specifications and feature flame retardant coating, moisture resistance, and safety certification. Both parts are RoHS non-compliant and REACH Affected, with identical compliance status.

Q: What inventory levels are available?

A: RN70D4023FRE6 has 854 units in stock (Tape & Reel format). RN70C4023BB14 has 1152 units in stock (Bulk format). Both parts are active production items from Vishay Dale.
