Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 4.99 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All listed substitute parts meet these core electrical and mechanical requirements. Variations in power rating, special features (automotive qualification, moisture resistance, pulse withstanding capability), and product status are noted but do not disqualify substitution when the core parameters align.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (No Feature Additions)

CRCW08054K99FKEAC from Vishay Dale is a direct electrical and mechanical equivalent with identical power rating and no additional features. This part is actively produced and suitable for direct substitution in applications requiring standard 0805 thick film resistors.

Enhanced Moisture Resistance

CR0805-FX-4991ELF from Bourns Inc. provides moisture-resistant construction while maintaining all core electrical parameters. This part is appropriate for applications exposed to high humidity or condensation environments.

Automotive Applications

CRCW08054K99FKEB from Vishay Dale and KTR10EZPF4991 from Rohm Semiconductor both carry AEC-Q200 automotive qualification. CRCW08054K99FKEB is discontinued at DiGi Electronics. KTR10EZPF4991 includes high-voltage capability and is actively produced, making it suitable for automotive designs requiring enhanced reliability.

Enhanced Power Handling

ESR10EZPF4991 from Rohm Semiconductor provides 0.4W power rating (versus 0.125W in the main part) with automotive AEC-Q200 qualification and pulse withstanding capability. This part is suitable for applications requiring higher transient power dissipation while maintaining the same resistance and tolerance.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher power rating?

A: Yes. A substitute with higher power rating (such as ESR10EZPF4991 at 0.4W) is electrically compatible with designs specified for 0.125W, provided the physical dimensions remain within PCB layout constraints. The 0805 package is maintained across all listed substitutes.

Q: What is the difference between standard and automotive-qualified versions?

A: Automotive-qualified parts (CRCW08054K99FKEB, KTR10EZPF4991, ESR10EZPF4991) carry AEC-Q200 certification, indicating compliance with automotive reliability and quality standards. These parts are suitable for automotive applications; standard versions are not certified for automotive use.

Q: Are all substitute parts in the same 0805 package?

A: Yes. All listed substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical interchangeability on PCB is confirmed.

Q: What does "Moisture Resistant" mean for CR0805-FX-4991ELF?

A: Moisture-resistant construction provides enhanced protection against moisture ingress and corrosion in high-humidity or condensation-prone environments. This feature does not affect electrical performance but improves long-term reliability in challenging environmental conditions.

Q: Can I substitute a part with higher temperature coefficient?

A: No. All listed substitutes maintain the ±100ppm/°C temperature coefficient specified for the main part. Temperature coefficient is a critical parameter for precision applications and must not be exceeded.

Q: Is CRCW08054K99FKEB still available?

A: CRCW08054K99FKEB is discontinued at DiGi Electronics. For automotive applications, KTR10EZPF4991 from Rohm Semiconductor is the recommended active alternative with AEC-Q200 qualification.
