Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN70C2202FRE6 is determined by the following critical parameters:

• Resistance value: 22 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Physical dimensions: 0.180" Dia x 0.562" L (exact match required)
• Series compliance: MIL-R-10509/3 (exact match required)

The identified substitute part RN70E2202FB14 meets all critical electrical and mechanical parameters. The primary difference is packaging format (Bulk versus Tape & Reel) and temperature coefficient specification (±25ppm/°C versus ±50ppm/°C for the main part).

Parameter Comparison

Engineering Selection Recommendations

Both RN70C2202FRE6 and RN70E2202FB14 are active production components from Vishay Dale with identical electrical specifications and military qualification. Selection between these parts should be based on:

Packaging requirements: The RN70C2202FRE6 is supplied in Tape & Reel format, suitable for automated assembly processes. The RN70E2202FB14 is supplied in Bulk format, suitable for manual assembly or alternative handling methods.

Inventory availability: The RN70E2202FB14 has higher stock levels (1689 units versus 767 units), providing greater availability for high-volume applications.

Temperature coefficient: The RN70E2202FB14 offers a tighter temperature coefficient specification (±25ppm/°C versus ±50ppm/°C), which may be advantageous for precision applications requiring enhanced temperature stability.

Compliance status: Both parts share identical RoHS and REACH compliance profiles, with no differentiation in regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can RN70E2202FB14 be used as a direct replacement for RN70C2202FRE6?

A: Yes. Both parts are electrically and mechanically identical with respect to resistance value, tolerance, power rating, composition, package type, and operating temperature range. The primary difference is packaging format (Bulk versus Tape & Reel) and temperature coefficient specification.

Q: What is the significance of the packaging format difference?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly equipment. Bulk packaging is suitable for manual assembly, kit assembly, or alternative distribution methods. The choice depends on your assembly process requirements.

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

A: The RN70E2202FB14 features a tighter temperature coefficient (±25ppm/°C) compared to the RN70C2202FRE6 (±50ppm/°C). This means the substitute part exhibits better resistance stability across temperature variations. Both parts maintain the same operating temperature range and all other electrical specifications.

Q: Do both parts meet military specifications?

A: Yes. Both RN70C2202FRE6 and RN70E2202FB14 comply with MIL-R-10509/3 military specification and are part of the RN70 military series.

Q: Are there any compliance or regulatory differences?

A: No. Both parts share identical RoHS and REACH compliance status. Both are RoHS non-compliant and REACH Affected, with the same ECCN and HTSUS classifications.

Q: Which part should I select for new designs?

A: Selection should be based on your specific assembly process and inventory requirements. If automated assembly is used, the Tape & Reel format (RN70C2202FRE6) is standard. If manual assembly or bulk handling is preferred, the Bulk format (RN70E2202FB14) is appropriate. The tighter temperature coefficient of RN70E2202FB14 may be beneficial for precision applications.
