Substitute Part Grouping Explanation

The RN55E2210BB14 qualifies as a direct substitute for the RN55C2210BRSL based on the following critical parameters:

• Identical resistance value: 221 Ohms
• Identical tolerance: ±0.1%
• Identical power rating: 0.125W (1/8W)
• Identical composition: Metal Film
• Identical package type: Axial
• Identical operating temperature range: -65°C to 175°C
• Identical series designation: Military, MIL-R-10509/7, RN55
• Identical physical dimensions: 0.090" Dia × 0.240" L (2.29mm × 6.10mm)
• Identical features: Flame Retardant Coating, Military, Moisture Resistant, Safety

The primary difference between these parts is packaging format (Tape & Reel versus Bulk) and temperature coefficient specification (±50ppm/°C versus ±25ppm/°C). Both parts maintain active production status and identical compliance profiles.

Parameter Comparison

Engineering Selection Recommendations

Both RN55C2210BRSL and RN55E2210BB14 are qualified substitutes within the RN55 military resistor series. Selection between these parts should be based on:

• Packaging requirements: RN55C2210BRSL is supplied in Tape & Reel format suitable for automated assembly; RN55E2210BB14 is supplied in Bulk format suitable for manual assembly or smaller quantity requirements.
• Temperature coefficient tolerance: RN55E2210BB14 provides a tighter temperature coefficient specification (±25ppm/°C) compared to RN55C2210BRSL (±50ppm/°C), offering improved stability across the operating temperature range when this performance margin is required.
• Inventory availability: Both parts maintain active production status with adequate stock levels (753 units and 1071 units respectively).
• Compliance: Both parts share identical RoHS non-compliant status, REACH Affected designation, and military series certification.

Frequently Asked Questions (FAQ)

Q: Can RN55E2210BB14 be used as a direct replacement for RN55C2210BRSL in existing designs?

A: Yes. Both parts are electrically and mechanically identical in all critical parameters: resistance value, tolerance, power rating, composition, package type, operating temperature range, and physical dimensions. The substitution is valid for circuit-level performance.

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

A: Tape & Reel (TR) packaging is used for automated pick-and-place assembly equipment in high-volume manufacturing. Bulk packaging is used for manual assembly, repair, or lower-volume applications. The component itself is identical; only the delivery format differs.

Q: Does the temperature coefficient difference affect substitution eligibility?

A: The RN55E2210BB14 has a tighter temperature coefficient (±25ppm/°C) compared to RN55C2210BRSL (±50ppm/°C). This means RN55E2210BB14 maintains more stable resistance across temperature variations. For applications requiring tighter temperature stability, RN55E2210BB14 is the preferred choice. For applications where the ±50ppm/°C specification is acceptable, both parts are equivalent.

Q: Are both parts compliant with military specifications?

A: Both parts are manufactured to MIL-R-10509/7 specifications and are part of the Military RN55 series. Both maintain identical military-grade features including flame retardant coating, moisture resistance, and safety characteristics.

Q: What is the inventory status for these parts?

A: RN55C2210BRSL has 753 units in stock (Tape & Reel format). RN55E2210BB14 has 1071 units in stock (Bulk format). Both parts are actively produced and available for procurement.
