Substitute Part Grouping Explanation

Substitution eligibility for the RN55C5620BRSL is determined by the following critical parameters:

• Resistance value: 562 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Military series compliance: MIL-R-10509/7, RN55 (exact match required)

The RN55E5620BB14 qualifies as a direct substitute based on identical electrical specifications and military series designation. The primary difference is packaging format (Bulk versus Tape & Reel) and temperature coefficient variance, which do not affect functional interchangeability in applications requiring the specified electrical and environmental parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C5620BRSL and RN55E5620BB14 maintain active product status and identical military-grade specifications. Selection between these parts should be based on:

Packaging requirements: The RN55C5620BRSL is supplied in Tape & Reel format, suitable for automated assembly processes. The RN55E5620BB14 is supplied in Bulk format, appropriate for manual assembly or lower-volume applications.

Temperature coefficient: The RN55E5620BB14 offers superior temperature stability at ±25ppm/°C compared to the RN55C5620BRSL at ±50ppm/°C. This difference is relevant only for applications with stringent temperature coefficient requirements.

Inventory availability: The RN55E5620BB14 provides higher stock levels (1440 units) compared to the RN55C5620BRSL (862 units), supporting extended production runs or supply chain continuity.

Both parts maintain identical compliance status (RoHS non-compliant, REACH Affected, ECCN EAR99) and are suitable for military and high-reliability applications requiring MIL-R-10509/7 certification.

Frequently Asked Questions (FAQ)

Q: Can RN55E5620BB14 replace RN55C5620BRSL in all applications?

A: Yes, the RN55E5620BB14 is electrically and mechanically equivalent to the RN55C5620BRSL. Both parts share identical resistance, tolerance, power rating, composition, package type, and operating temperature range. The primary difference is packaging format (Bulk versus Tape & Reel) and temperature coefficient performance.

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

A: Tape & Reel packaging is optimized for automated pick-and-place assembly equipment used in high-volume manufacturing. Bulk packaging is suitable for manual assembly, lower-volume production, or applications where automated handling is not required. The electrical and mechanical properties of the resistor remain identical regardless of packaging format.

Q: Does the temperature coefficient difference affect substitution eligibility?

A: The RN55E5620BB14 features a ±25ppm/°C temperature coefficient, while the RN55C5620BRSL features ±50ppm/°C. This difference does not prevent substitution but should be considered in applications with strict temperature stability requirements. The superior temperature coefficient of the RN55E5620BB14 may provide performance advantages in temperature-sensitive circuits.

Q: Are both parts compliant with military specifications?

A: Yes, both the RN55C5620BRSL and RN55E5620BB14 are certified to MIL-R-10509/7 and are part of the military-grade RN55 series. Both maintain identical compliance status regarding RoHS (non-compliant), REACH (Affected), and ECCN (EAR99) classifications.

Q: What inventory considerations should guide part selection?

A: The RN55E5620BB14 maintains higher stock levels (1440 units) compared to the RN55C5620BRSL (862 units). For applications requiring extended production runs or supply chain continuity, the RN55E5620BB14 may provide better availability assurance.
