Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RN60D3012FB14 are qualified based on the following critical parameters:

• Electrical Match: Resistance value of 30.1 kOhms with ±1% tolerance
• Power Rating: 0.25W (1/4W) minimum
• Package Configuration: Axial through-hole with 2 terminations
• Composition: Metal film construction
• Mechanical Compatibility: Physical dimensions and termination style compatible with axial PCB mounting

The RN60C3012FB14 (Vishay Dale) qualifies as a direct upgrade substitute with identical electrical and mechanical specifications. The MFR-25FRF52-30K1 (YAGEO) qualifies as a functional equivalent with matching core electrical parameters and package type, though with dimensional and temperature coefficient variations within acceptable tolerance for most applications.

Parameter Comparison

Engineering Selection Recommendations

RN60C3012FB14 (Vishay Dale): This part is the direct upgrade substitute with identical specifications to the RN60D3012FB14. It maintains the same military series designation (MIL-R-10509/1 RN60), operating temperature range (-65°C ~ 175°C), and physical dimensions. The improved temperature coefficient (±50ppm/°C versus ±100ppm/°C) provides enhanced stability. Both parts share RoHS non-compliant status. Selection of this substitute is appropriate for direct replacement in existing designs without layout or thermal modifications.

MFR-25FRF52-30K1 (YAGEO): This part provides functional equivalence with matching electrical core specifications (30.1 kOhms ±1%, 0.25W metal film). The primary differences are reduced physical dimensions (0.094" Dia x 0.248" L), narrower operating temperature range (-55°C ~ 155°C), and ROHS3 compliance. This substitute is suitable for applications where RoHS compliance is required or where compact board layout is beneficial. The reduced temperature range and smaller footprint must be verified against circuit requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can RN60C3012FB14 be used as a direct replacement for RN60D3012FB14?

A: Yes. The RN60C3012FB14 is a direct substitute with identical resistance, tolerance, power rating, package type, and physical dimensions. The improved temperature coefficient (±50ppm/°C) represents an upgrade in performance stability.

Q: What are the key differences between RN60D3012FB14 and MFR-25FRF52-30K1?

A: Both parts match on resistance (30.1 kOhms), tolerance (±1%), power rating (0.25W), and package type (axial metal film). The MFR-25FRF52-30K1 has smaller physical dimensions (0.094" Dia x 0.248" L versus 0.145" Dia x 0.344" L), a narrower operating temperature range (-55°C ~ 155°C versus -65°C ~ 175°C), and is ROHS3 compliant while the RN60D3012FB14 is not.

Q: Is the MFR-25FRF52-30K1 suitable for military applications?

A: The MFR-25FRF52-30K1 is not designated as a military-grade component. The RN60D3012FB14 and RN60C3012FB14 are both part of the Military MIL-R-10509/1 series. If military specification compliance is required, use RN60C3012FB14 as the substitute.

Q: Can MFR-25FRF52-30K1 be used in applications requiring -65°C operation?

A: No. The MFR-25FRF52-30K1 operating temperature range is -55°C ~ 155°C. Applications requiring operation at -65°C must use RN60D3012FB14 or RN60C3012FB14.

Q: Are there packaging differences between these parts?

A: RN60D3012FB14 and RN60C3012FB14 are supplied in Bulk packaging. MFR-25FRF52-30K1 is supplied in Cut Tape (CT) packaging. Physical dimensions differ: the YAGEO part is smaller (0.094" Dia x 0.248" L) compared to the Vishay Dale parts (0.145" Dia x 0.344" L).

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For military specifications and extended temperature range (-65°C ~ 175°C), use RN60C3012FB14. For RoHS compliance and compact layout, use MFR-25FRF52-30K1 if the operating temperature range (-55°C ~ 155°C) is acceptable.
