Parameter Comparison

Engineering Selection Recommendations

Both RN60D2490FRE6 and RN60C2490FB14 are active military-grade components suitable for direct substitution in applications requiring 249 Ohm, 1/4W metal film resistors. Selection between these parts should be based on:

RN60D2490FRE6 (Tape & Reel packaging): Select when automated assembly processes require tape and reel format delivery.

RN60C2490FB14 (Bulk packaging): Select when bulk packaging is acceptable for assembly operations. This variant offers improved temperature coefficient performance (±50ppm/°C versus ±100ppm/°C), providing enhanced frequency stability in temperature-sensitive applications.

Both parts comply with MIL-R-10509/1 military specifications and maintain identical electrical and mechanical characteristics across the full operating temperature range of -65°C to 175°C. RoHS non-compliance status is identical for both variants.

Frequently Asked Questions (FAQ)

Q: Can RN60C2490FB14 replace RN60D2490FRE6 in existing designs?

A: Yes. Both components have identical resistance values, tolerance, power ratings, physical dimensions, and operating temperature ranges. The primary difference is packaging format (Bulk versus Tape & Reel) and temperature coefficient performance. RN60C2490FB14 provides superior temperature stability.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient indicates resistance value drift with temperature change. RN60C2490FB14 at ±50ppm/°C exhibits half the drift rate of RN60D2490FRE6 at ±100ppm/°C. For applications with strict frequency or impedance stability requirements across the -65°C to 175°C operating range, RN60C2490FB14 is the preferred selection.

Q: Are both parts suitable for military applications?

A: Yes. Both components are manufactured to MIL-R-10509/1 specifications and feature flame retardant coating, moisture resistance, and safety characteristics required for military use.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Bulk packaging formats contain identical components. Packaging selection is determined by assembly process requirements and inventory management practices.

Q: What is the inventory status for each part?

A: RN60D2490FRE6 has 902 units in stock. RN60C2490FB14 has 1329 units in stock. Both are active production items.
