Substitute Part Grouping Explanation

Substitution eligibility for the RN70D1003FRE6 is determined by the following critical parameters:

• Resistance value: 100 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series compliance: MIL-R-10509/3, RN70 (exact match required)
• Physical dimensions: 0.180" Dia × 0.562" L (exact match required)

The identified substitute part RN70C1003FB14 meets all critical electrical and mechanical parameters. The primary difference is packaging format (Bulk versus Tape & Reel) and temperature coefficient specification (±50ppm/°C versus ±100ppm/°C for the main part).

Parameter Comparison

Engineering Selection Recommendations

Both RN70D1003FRE6 and RN70C1003FB14 are active production components from Vishay Dale's military-grade RN70 series. Selection between these parts should be based on packaging requirements and procurement workflow:

RN70D1003FRE6 is supplied in Tape & Reel format, suitable for automated assembly processes and high-volume production environments. This packaging format is standard for pick-and-place machine operations.

RN70C1003FB14 is supplied in Bulk packaging, appropriate for manual assembly, kit builds, or applications where tape-and-reel format is not required. This part features an improved temperature coefficient specification (±50ppm/°C) compared to the main part (±100ppm/°C), providing enhanced stability across the operating temperature range.

Both parts maintain identical electrical specifications (100 kOhms ±1%, 0.75W), mechanical dimensions (0.180" Dia × 0.562" L), and military compliance (MIL-R-10509/3). Both are RoHS non-compliant and REACH Affected, with identical regulatory classifications (ECCN: EAR99, HTSUS: 8533.21.0090).

Frequently Asked Questions (FAQ)

Q: Can RN70C1003FB14 be used as a direct replacement for RN70D1003FRE6?

A: Yes. Both parts share identical electrical specifications (100 kOhms ±1%, 0.75W), composition (metal film), package type (axial), and physical dimensions (0.180" Dia × 0.562" L). The primary difference is packaging format: Tape & Reel versus Bulk. The substitute part features an improved temperature coefficient (±50ppm/°C versus ±100ppm/°C).

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, designed for automated assembly equipment. Bulk packaging supplies loose components in quantities suitable for manual assembly or kit applications. Both formats contain identical components.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. Both are certified to MIL-R-10509/3 specification.

Q: Does the temperature coefficient difference affect substitution eligibility?

A: The RN70C1003FB14 substitute features a tighter temperature coefficient (±50ppm/°C) compared to the main part (±100ppm/°C). This represents improved performance stability and does not restrict substitution. Applications requiring the tighter specification can use the substitute; applications tolerant of ±100ppm/°C can use either part.

Q: What inventory levels are available?

A: RN70D1003FRE6 (Tape & Reel) has 918 units in stock. RN70C1003FB14 (Bulk) has 1421 units in stock.
