Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN60D1200FRE6 is determined by the following critical parameters: resistance value (120 Ohms), power rating (0.25W), tolerance specification, composition (metal film), axial package format, temperature range (-65°C to 175°C), and military series classification (MIL-R-10509/1, RN60 base product).

The identified substitutes maintain identical electrical specifications (120 Ohms, 0.25W, metal film, axial configuration) and mechanical dimensions (0.145" Dia × 0.344" L). Variations exist in packaging format (Tape & Reel versus Bulk) and tolerance grade. RN60D1200FB14 provides direct equivalence with identical ±1% tolerance and Bulk packaging. RN60C1200BB14 represents an upgrade option with tighter ±0.1% tolerance and improved temperature coefficient (±50ppm/°C versus ±100ppm/°C), also supplied in Bulk format.

Parameter Comparison

Engineering Selection Recommendations

RN60D1200FB14 serves as the direct functional equivalent to RN60D1200FRE6, maintaining identical electrical performance and tolerance specifications. The primary distinction is packaging format: RN60D1200FB14 is supplied in Bulk configuration rather than Tape & Reel. Both parts are active products with established supply chains and identical military compliance certifications.

RN60C1200BB14 functions as an upgraded alternative, offering superior tolerance (±0.1% versus ±1%) and improved temperature stability (±50ppm/°C versus ±100ppm/°C). This upgrade is applicable in applications requiring tighter resistance accuracy or enhanced thermal performance within the -65°C to 175°C operating range. All three parts maintain identical mechanical form factor, enabling direct board-level substitution.

Selection between direct equivalent and upgrade should be based on circuit tolerance requirements and thermal environment specifications. All parts retain active production status and military series classification (MIL-R-10509/1, RN60).

Frequently Asked Questions (FAQ)

Q: Can RN60D1200FB14 replace RN60D1200FRE6 in existing designs?

A: Yes. RN60D1200FB14 is electrically and mechanically identical to RN60D1200FRE6. The only difference is packaging format (Bulk versus Tape & Reel). Both maintain ±1% tolerance, 0.25W power rating, identical dimensions, and military series compliance. Board-level substitution is direct.

Q: What is the difference between RN60D1200FB14 and RN60C1200BB14?

A: RN60C1200BB14 provides tighter tolerance (±0.1% versus ±1%) and improved temperature coefficient (±50ppm/°C versus ±100ppm/°C). Electrical resistance value, power rating, package type, and operating temperature range remain identical. RN60C1200BB14 is suitable for applications requiring higher accuracy.

Q: Are all three parts compatible with military specifications?

A: Yes. All three parts conform to MIL-R-10509/1 specification and belong to the RN60 military series. All are active products with identical compliance certifications (RoHS non-compliant, REACH Affected, ECCN EAR99).

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Bulk packaging formats do not affect electrical or mechanical performance. The difference is in supply configuration and handling. RN60D1200FRE6 (Tape & Reel) and RN60D1200FB14 (Bulk) are electrically identical.

Q: Can RN60C1200BB14 be used in applications designed for ±1% tolerance parts?

A: Yes. RN60C1200BB14 with ±0.1% tolerance exceeds the ±1% requirement and is fully compatible. Tighter tolerance represents improved performance and does not create incompatibility with designs specified for ±1% tolerance.
