Parameter Comparison

Engineering Selection Recommendations

Both RN55E1004FRE6 and RN55E1004BB14 maintain active product status and identical military-grade specifications under MIL-R-10509/7. Selection between these parts depends on application requirements and procurement constraints:

The RN55E1004FRE6 in Tape & Reel packaging is suitable for automated assembly processes requiring continuous component feed. The RN55E1004BB14 in Bulk packaging accommodates manual assembly or lower-volume production runs. The tolerance upgrade from ±1% to ±0.1% in the RN55E1004BB14 provides enhanced precision for circuits requiring tighter resistance values, though both parts satisfy identical electrical and thermal operating parameters. Compliance status remains consistent across both variants with RoHS non-compliance and REACH Affected designation.

Frequently Asked Questions (FAQ)

Q: Can RN55E1004BB14 replace RN55E1004FRE6 in my circuit?

A: Yes. Both parts share identical resistance value (1 MOhms), power rating (0.125W), temperature coefficient (±25ppm/°C), operating temperature range (-65°C to 175°C), and physical dimensions (0.090" Dia x 0.240" L). The RN55E1004BB14 provides superior tolerance (±0.1% versus ±1%), making it functionally compatible and electrically superior for precision applications.

Q: What is the difference in packaging between these parts?

A: RN55E1004FRE6 is supplied in Tape & Reel (TR) format for automated pick-and-place assembly. RN55E1004BB14 is supplied in Bulk format for manual handling or lower-volume assembly operations. Both contain identical component specifications.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS non-compliant and REACH Affected status. Compliance certifications and regulatory designations are consistent across both variants.

Q: Does the tolerance difference affect circuit performance?

A: The RN55E1004BB14 tolerance of ±0.1% provides tighter resistance accuracy compared to the ±1% tolerance of RN55E1004FRE6. Applications requiring precise resistance values benefit from the RN55E1004BB14. For general-purpose circuits tolerating ±1% variation, both parts perform identically.

Q: Are both parts military-grade components?

A: Yes. Both RN55E1004FRE6 and RN55E1004BB14 are manufactured under the military RN55 series per MIL-R-10509/7 specification with flame retardant coating, moisture resistance, and safety-rated construction.
