Substitute Part Grouping Explanation

Substitution for the RN55C1001DR36 is based on the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 1 kOhms (exact match required)
• Power rating: 0.125W (1/8W) minimum
• Package type: Axial through-hole
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Operating temperature range: -65°C to 175°C (minimum)
• Composition: Metal film
• Series compliance: MIL-R-10509/7, RN55

Allowable Parameter Variations:

• Tolerance: May be tighter (lower value) than ±0.5%
• Temperature coefficient: May be lower than ±50ppm/°C
• Packaging format: Bulk or Cut Tape acceptable as functional equivalents

The identified substitute parts RN55E1001BB14 and RN55E1001BRE6 meet all mandatory compatibility requirements and offer improved tolerance specifications (±0.1%) and lower temperature coefficients (±25ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

All three parts—RN55C1001DR36, RN55E1001BB14, and RN55E1001BRE6—are active products from Vishay Dale with identical military-grade specifications and compliance status. The substitute parts RN55E1001BB14 and RN55E1001BRE6 provide tighter tolerance (±0.1% versus ±0.5%) and improved temperature coefficient stability (±25ppm/°C versus ±50ppm/°C) while maintaining full mechanical and thermal compatibility.

Selection between substitute parts depends on packaging requirements: RN55E1001BB14 is supplied in Bulk format, while RN55E1001BRE6 is supplied in Cut Tape format. Both are functionally equivalent to the original RN55C1001DR36 Tape & Reel format for circuit board assembly applications.

Frequently Asked Questions (FAQ)

Q: Can RN55E1001BB14 or RN55E1001BRE6 be used as direct replacements for RN55C1001DR36?

A: Yes. Both substitute parts are direct functional equivalents. They share identical resistance values, power ratings, physical dimensions, operating temperature ranges, and military series compliance. The substitute parts offer improved tolerance and temperature coefficient specifications.

Q: What is the difference between the packaging formats?

A: RN55C1001DR36 is supplied in Tape & Reel format for automated assembly. RN55E1001BB14 is supplied in Bulk format (loose components), and RN55E1001BRE6 is supplied in Cut Tape format. The functional performance is identical; packaging format selection depends on assembly process requirements.

Q: Are there any compliance or certification differences?

A: No. All three parts share identical RoHS status (non-compliant), REACH status (affected), ECCN classification (EAR99), and HTSUS codes. Military series compliance (MIL-R-10509/7, RN55) is maintained across all variants.

Q: Why would I choose a substitute part with tighter tolerance?

A: Tighter tolerance (±0.1% versus ±0.5%) reduces resistance value variation across production batches, which improves circuit performance in precision applications. Lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) provides better stability across the full operating temperature range.

Q: Are the physical dimensions identical?

A: Yes. All three parts have identical axial package dimensions of 0.090" diameter by 0.240" length (2.29mm x 6.10mm), ensuring mechanical compatibility in PCB layouts and through-hole assembly processes.
