Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN60D3922FRE6 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 39.2 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)

Mechanical Parameters:

• Package type: Axial (exact match required)
• Physical dimensions: 0.145" Dia x 0.344" L / 3.68mm x 8.74mm (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• Military specification: MIL-R-10509/1 (exact match required)
• Features: Flame Retardant Coating, Military, Moisture Resistant, Safety (exact match required)

Substitute parts must maintain identical electrical performance, mechanical fit, and military compliance. Packaging format (Cut Tape vs. Bulk) does not affect electrical or mechanical substitution eligibility.

Engineering Selection Recommendations

RN60D3922FRE6 (Main Part): The RN60D3922FRE6 is the primary specification for applications requiring Cut Tape packaging format. This part is active in production with established inventory levels (1527 units in stock). It meets all military specifications under MIL-R-10509/1 and maintains full compliance with REACH and ECCN regulations. The temperature coefficient of ±100ppm/°C is suitable for standard military and high-reliability applications within the specified operating range of -65°C to 175°C.

RN60C3922FB14 (Substitute Part): The RN60C3922FB14 provides electrical and mechanical equivalence with an improved temperature coefficient specification of ±50ppm/°C, representing superior thermal stability compared to the main part. This substitute is appropriate for applications where Bulk packaging format is acceptable and enhanced temperature coefficient performance is beneficial. The part is active in production with 1001 units in stock. All military specifications, compliance certifications, and physical dimensions remain identical to the main part.

Selection Criteria:

• Use RN60D3922FRE6 when Cut Tape packaging is required for automated assembly processes
• Use RN60C3922FB14 when Bulk packaging is acceptable and improved temperature coefficient performance is advantageous
• Both parts are electrically and mechanically interchangeable within the specified parameter tolerances
• Both parts maintain identical compliance status and military specifications

Frequently Asked Questions (FAQ)

Q: Are RN60D3922FRE6 and RN60C3922FB14 electrically interchangeable?

A: Yes. Both parts have identical resistance (39.2 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), and operating temperature range (-65°C to 175°C). The RN60C3922FB14 features a superior temperature coefficient (±50ppm/°C vs. ±100ppm/°C), which provides better thermal stability but does not prevent interchangeability.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape (CT) packaging is supplied on continuous tape and is cut to length for automated pick-and-place assembly. Bulk packaging supplies loose components. The electrical and mechanical properties of the resistor are identical; packaging format only affects handling and assembly methodology.

Q: Can I substitute RN60C3922FB14 for RN60D3922FRE6 in existing designs?

A: Yes. The RN60C3922FB14 is a direct substitute with identical electrical specifications, mechanical dimensions, and military compliance. The improved temperature coefficient of the substitute part does not create compatibility issues in applications designed for the main part.

Q: Do both parts meet military specifications?

A: Yes. Both RN60D3922FRE6 and RN60C3922FB14 comply with MIL-R-10509/1 military specification and include flame retardant coating, moisture resistance, and safety features.

Q: What is the physical size of these resistors?

A: Both parts have identical axial package dimensions of 0.145" diameter by 0.344" length (3.68mm x 8.74mm). They are mechanically interchangeable in all through-hole applications.

Q: Are there any compliance differences between the two parts?

A: No. Both parts have identical RoHS status (non-compliant), REACH status (affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090).

Q: Which part should I select for new designs?

A: Selection depends on packaging requirements and assembly methodology. For automated assembly with tape-fed systems, use RN60D3922FRE6. For manual assembly or applications where bulk components are preferred, use RN60C3922FB14. The improved temperature coefficient of RN60C3922FB14 makes it suitable for applications requiring enhanced thermal stability.
