Parameter Comparison

Engineering Selection Recommendations

Both the RN55D5620FRE6 and RN55E5620BB14 maintain active product status and identical military specification compliance under MIL-R-10509/7. Selection between these parts should be based on the following criteria:

Select RN55D5620FRE6 when:

• Tape and reel packaging is required for automated assembly processes
• Standard ±1% tolerance meets circuit requirements
• Temperature coefficient of ±100ppm/°C is acceptable for the application

Select RN55E5620BB14 when:

• Bulk packaging is acceptable or preferred for manual assembly or stock management
• Enhanced tolerance of ±0.1% is required for precision circuit applications
• Improved temperature coefficient of ±25ppm/°C is necessary for temperature-sensitive circuits

Both parts share identical RoHS non-compliant and REACH Affected regulatory status, requiring equivalent compliance documentation for procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can RN55E5620BB14 be used as a direct replacement for RN55D5620FRE6 in existing designs?

A: Yes. Both parts are electrically and mechanically compatible. The RN55E5620BB14 provides superior tolerance (±0.1% vs ±1%) and temperature coefficient (±25ppm/°C vs ±100ppm/°C), making it suitable for applications requiring higher precision. The primary difference is packaging format: tape and reel versus bulk.

Q: What is the significance of the tolerance difference between these parts?

A: The RN55D5620FRE6 has ±1% tolerance, meaning the actual resistance can vary between 556.38 and 567.62 Ohms. The RN55E5620BB14 has ±0.1% tolerance, constraining the actual resistance between 561.438 and 562.562 Ohms. Applications requiring tighter resistance values should specify the RN55E5620BB14.

Q: How does the temperature coefficient affect part selection?

A: Temperature coefficient indicates resistance change per degree Celsius. The RN55D5620FRE6 at ±100ppm/°C will experience greater resistance drift across the -65°C to 175°C operating range compared to the RN55E5620BB14 at ±25ppm/°C. Circuits sensitive to resistance variation with temperature should use the RN55E5620BB14.

Q: Are there packaging considerations for assembly?

A: Yes. The RN55D5620FRE6 is supplied in tape and reel format, suitable for pick-and-place automated assembly. The RN55E5620BB14 is supplied in bulk format, typically used for manual assembly or when tape and reel packaging is not required. Verify your assembly process requirements before selecting.

Q: Do both parts meet the same military specifications?

A: Yes. Both parts conform to MIL-R-10509/7 military specification and share identical flame retardant coating, moisture resistance, and safety features. Both maintain active product status with equivalent regulatory compliance (RoHS non-compliant, REACH Affected).
