Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55E2210DR36 is determined by the following critical parameters:

• Resistance Value: Must be 221 Ohms (exact match required)
• Power Rating: Must be 0.125W (1/8W) minimum
• Package Type: Must be Axial configuration
• Physical Dimensions: Must be 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Composition: Must be Metal Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -65°C to 175°C minimum
• Series Compliance: Military-grade RN55 series per MIL-R-10509/7

The RN55E2210BB14 qualifies as a substitute part. While it differs in tolerance specification (±0.1% versus ±0.5%) and packaging format (Bulk versus Tape & Reel), all critical electrical and mechanical parameters remain identical. The tighter tolerance of the substitute represents an upgrade in precision without affecting form factor or thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both RN55E2210DR36 and RN55E2210BB14 are active production components manufactured by Vishay Dale under identical military specifications. Selection between these parts should be based on:

Packaging Requirements: The RN55E2210DR36 is supplied in Tape & Reel format, suitable for automated assembly processes. The RN55E2210BB14 is supplied in Bulk format, appropriate for manual assembly or alternative handling methods.

Tolerance Specification: The RN55E2210BB14 provides ±0.1% tolerance compared to the ±0.5% tolerance of the RN55E2210DR36. This represents improved precision and may be selected when circuit design requires tighter resistance values.

Compliance Status: Both parts maintain identical RoHS non-compliant status, REACH Affected designation, ECCN EAR99 classification, and HTSUS code 8533.21.0090. No compliance advantage exists between the two options.

Inventory Availability: Current stock levels are 906 units for RN55E2210DR36 and 1071 units for RN55E2210BB14, providing flexibility in procurement planning.

Frequently Asked Questions (FAQ)

Q: Can RN55E2210BB14 be used as a direct replacement for RN55E2210DR36 in existing circuit designs?

A: Yes. Both parts share identical electrical characteristics (221 Ohms, 0.125W, ±25ppm/°C, -65°C to 175°C operating range) and physical dimensions (0.090" Dia x 0.240" L). The primary difference is packaging format and tolerance specification. Circuit-level functionality remains unchanged.

Q: What is the significance of the tolerance difference between ±0.5% and ±0.1%?

A: Tolerance defines the acceptable resistance variation from the nominal 221 Ohm value. RN55E2210DR36 allows variation between 220.095 and 221.905 Ohms. RN55E2210BB14 allows variation between 220.779 and 221.221 Ohms. The tighter tolerance of the substitute provides greater precision for applications requiring strict resistance values.

Q: Are there any thermal or environmental performance differences?

A: No. Both parts operate across the identical temperature range (-65°C to 175°C) with identical temperature coefficient (±25ppm/°C). Military-grade construction, flame retardant coating, and moisture resistance specifications are identical.

Q: How does packaging format affect component selection?

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 handling methods. Electrical and mechanical performance is independent of packaging format.

Q: Are both parts compliant with current regulations?

A: Both RN55E2210DR36 and RN55E2210BB14 maintain identical regulatory status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. No compliance advantage exists between the two options.
