Substitute Part Grouping Explanation

Substitute parts for the RN60D4991FRE6 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 4.99 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Operating temperature range: -65°C to 175°C
• Series: RN60 military classification

Mechanical Parameters (Must Match):

• Package type: Axial
• Physical dimensions: 0.145" Dia × 0.344" L (3.68mm × 8.74mm)
• Number of terminations: 2

Variable Parameters (Allowed to Differ):

• Packaging format (Cut Tape vs. Bulk)
• Temperature coefficient (±100ppm/°C vs. ±50ppm/°C)

The RN60D4991FRE6 has two qualified substitutes: RN60D4991FB14 (packaging variant) and RN60C4991FRE6 (performance upgrade variant with improved temperature coefficient).

Parameter Comparison

Engineering Selection Recommendations

RN60D4991FB14 Selection Criteria: Use RN60D4991FB14 when bulk packaging format is acceptable for assembly operations. This substitute maintains identical electrical specifications and physical dimensions. Packaging differs only in format (Bulk vs. Cut Tape), with no impact on component performance or circuit compatibility. Both parts carry active product status and equivalent military classification.

RN60C4991FRE6 Selection Criteria: Use RN60C4991FRE6 when enhanced temperature stability is required. This upgrade variant reduces temperature coefficient from ±100ppm/°C to ±50ppm/°C, providing superior resistance stability across the full operating temperature range (-65°C to 175°C). Cut Tape packaging matches the main part format. Both maintain active product status and full military compliance.

Compliance Considerations: All three parts share identical RoHS non-compliant status, REACH Affected classification, ECCN EAR99, and HTSUS code 8533.21.0090. No compliance advantage exists between variants.

Frequently Asked Questions (FAQ)

Q: Can RN60D4991FB14 be used as a direct replacement for RN60D4991FRE6? A: Yes. RN60D4991FB14 is electrically and mechanically identical to RN60D4991FRE6. The only difference is packaging format (Bulk vs. Cut Tape). Circuit performance and component specifications remain unchanged.

Q: What is the advantage of RN60C4991FRE6 over the main part? A: RN60C4991FRE6 provides improved temperature coefficient performance (±50ppm/°C vs. ±100ppm/°C). This results in better resistance stability across temperature variations, beneficial for precision circuits operating across the full -65°C to 175°C range.

Q: Are all three parts interchangeable in the same circuit? A: Yes, all three parts are interchangeable from an electrical and mechanical standpoint. Selection depends on packaging requirements (Cut Tape vs. Bulk) and temperature stability needs.

Q: Does packaging format affect circuit performance? A: No. Cut Tape and Bulk packaging formats contain identical components. Packaging format affects only handling, storage, and assembly logistics, not electrical or mechanical performance.

Q: What is the temperature coefficient and why does it matter? A: Temperature coefficient measures resistance change per degree Celsius. RN60D4991FRE6 and RN60D4991FB14 have ±100ppm/°C; RN60C4991FRE6 has ±50ppm/°C. Lower values indicate better stability in temperature-sensitive applications.

Q: Are there any compliance differences between the three parts? A: No. All three parts share identical RoHS status (non-compliant), REACH classification (Affected), and military series designation (MIL-R-10509/1, RN60).
