Substitute Part Grouping Explanation

The RN70E4703FB14 qualifies as a direct electrical and mechanical substitute for the RN70E4703FRE6 based on the following criteria:

Identical Parameters:

• Resistance value: 470 kOhms
• Tolerance: ±1%
• Power rating: 0.75W (3/4W)
• Composition: Metal Film
• Package case: Axial
• Physical dimensions: 0.180" Dia x 0.562" L (4.57mm x 14.27mm)
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -65°C to 175°C
• Series classification: Military, MIL-R-10509/3, RN70
• Features: Flame Retardant Coating, Military, Moisture Resistant, Safety

Difference:

• Packaging format: RN70E4703FRE6 supplied in Tape & Reel (TR); RN70E4703FB14 supplied in Bulk

The substitution is valid because packaging format does not affect electrical performance or mechanical compatibility in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both RN70E4703FRE6 and RN70E4703FB14 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements:

• RN70E4703FRE6 (Tape & Reel): Suitable for automated assembly processes requiring reel-fed component handling.
• RN70E4703FB14 (Bulk): Suitable for manual assembly, repair, or applications where reel packaging is not required.

Both parts maintain RoHS non-compliant status and REACH Affected classification. No compliance or certification differences exist between the two variants. Component selection may also consider inventory availability and supply chain lead times, as both parts maintain active stock levels.

Frequently Asked Questions (FAQ)

Q: Can RN70E4703FB14 replace RN70E4703FRE6 in production assembly?

A: Yes, provided the assembly process can accommodate bulk packaging. The electrical and mechanical specifications are identical. Automated reel-fed systems require the Tape & Reel format (RN70E4703FRE6), while manual assembly can use either format.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical resistance value (470 kOhms), tolerance (±1%), power rating (0.75W), temperature coefficient (±25ppm/°C), and operating temperature range (-65°C to 175°C).

Q: What is the physical difference between these substitute parts?

A: The only difference is packaging format. RN70E4703FRE6 is supplied in Tape & Reel format for automated handling, while RN70E4703FB14 is supplied in bulk packaging. Physical component dimensions and form factor are identical.

Q: Do both parts meet military specifications?

A: Yes. Both parts are classified as military-grade components per MIL-R-10509/3 and feature flame retardant coating, moisture resistance, and safety certification.

Q: Which part should I select for new designs?

A: Selection depends on manufacturing process requirements. For automated assembly lines, use RN70E4703FRE6 (Tape & Reel). For manual assembly or repair applications, either part is suitable based on availability and procurement preference.
