Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN70C4023FRE6 is determined by the following critical parameters:

• Resistance Value: Must be 402 kOhms
• Power Rating: Must be 0.75W minimum
• Composition: Must be metal film
• Temperature Coefficient: Must be ±50ppm/°C or better
• Operating Temperature Range: Must support -65°C to 175°C
• Package Type: Must be axial configuration
• Physical Dimensions: Must be 0.180" Dia × 0.562" L
• Series Compliance: Must comply with MIL-R-10509/3 military specification
• Tolerance: ±1% or tighter tolerance acceptable

The RN70C4023BB14 qualifies as a substitute part because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±0.1% versus ±1%).

Parameter Comparison

Engineering Selection Recommendations

Both the RN70C4023FRE6 and RN70C4023BB14 are active production components manufactured by Vishay Dale within the military-qualified RN70 series. Selection between these parts should be based on the following criteria:

RN70C4023FRE6 is appropriate when tape and reel packaging is required for automated assembly processes and ±1% tolerance meets circuit requirements.

RN70C4023BB14 is appropriate when tighter tolerance specification (±0.1%) is required for precision applications and bulk packaging is acceptable. The improved tolerance provides enhanced accuracy for circuits with stringent resistance value requirements.

Both parts maintain identical compliance status regarding RoHS non-compliance and REACH applicability. Neither part introduces additional regulatory constraints. Selection should prioritize packaging format compatibility with assembly infrastructure and tolerance requirements of the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can RN70C4023BB14 be used as a direct replacement for RN70C4023FRE6?

A: Yes. Both parts share identical resistance value (402 kOhms), power rating (0.75W), physical dimensions (0.180" Dia × 0.562" L), temperature coefficient (±50ppm/°C), and operating temperature range (-65°C to 175°C). The RN70C4023BB14 offers improved tolerance (±0.1% versus ±1%), making it suitable for applications requiring higher precision.

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

A: The main differences are tolerance specification and packaging format. RN70C4023FRE6 provides ±1% tolerance in tape and reel packaging, while RN70C4023BB14 provides ±0.1% tolerance in bulk packaging.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS non-compliance status and REACH applicability. Both comply with MIL-R-10509/3 military specification and share identical feature sets including flame retardant coating, moisture resistance, and safety certification.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (tape and reel versus bulk) does not affect electrical characteristics. Selection should be based on assembly process requirements and inventory management practices.

Q: Can these parts be mixed in the same circuit board assembly?

A: Yes. Since both parts are electrically and mechanically identical except for tolerance specification, they can be used interchangeably in the same circuit design. However, mixing parts with different tolerances may introduce slight variations in circuit performance if tolerance-sensitive applications are involved.
