Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 9.53 kOhms (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Allowable Variations:

• Tolerance: May be equal to or tighter than ±0.25%
• Power rating: May be equal to or greater than 0.1W
• Temperature coefficient: May be equal to or lower than ±50ppm/°C
• Manufacturer: Different manufacturers permitted if all mandatory parameters match

All identified substitute parts meet or exceed the mandatory compatibility parameters of the RT0603CRE079K53L.

Parameter Comparison

Engineering Selection Recommendations

YAGEO RT0603BRD079K53L and RT0603BRE079K53L: Direct upgrades from the original RT0603CRE079K53L within the same manufacturer series. Both offer tighter tolerance (±0.1% versus ±0.25%), improving circuit precision. RT0603BRD079K53L additionally reduces temperature coefficient to ±25ppm/°C. Selection between these two depends on whether lower temperature coefficient is required for the application.

TE Connectivity 9-2176088-8: Suitable for applications requiring higher power dissipation (0.167W versus 0.1W). Offers ±0.1% tolerance and ±25ppm/°C temperature coefficient. Dimensions are nominally equivalent (1.55mm L versus 1.60mm L), with height reduced to 0.020" (0.50mm).

Panasonic ERA-3AEB9531V: Qualified to AEC-Q200 automotive standard. Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient. Suitable for automotive and high-reliability applications requiring automotive-grade component certification.

Susumu RG1608P-9531-B-T5: Qualified to AEC-Q200 automotive standard with anti-sulfur coating. Offers ±0.1% tolerance and ±25ppm/°C temperature coefficient. Recommended for automotive applications in corrosive environments or where anti-sulfur protection is specified.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD079K53L replace RT0603CRE079K53L directly?

A: Yes. Both are 9.53 kOhms ±0.1% thin film resistors in 0603 package with identical power rating and operating temperature range. RT0603BRD079K53L provides improved tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between RT0603BRD079K53L and RT0603BRE079K53L?

A: Both offer ±0.1% tolerance. RT0603BRD079K53L has ±25ppm/°C temperature coefficient, while RT0603BRE079K53L maintains ±50ppm/°C. Selection depends on temperature stability requirements of the circuit.

Q: Can automotive-qualified parts (ERA-3AEB9531V, RG1608P-9531-B-T5) be used in non-automotive applications?

A: Yes. Automotive-qualified components meet or exceed general industrial specifications. AEC-Q200 certification indicates enhanced reliability and environmental stress testing. These parts are suitable for any application requiring the specified electrical and mechanical parameters.

Q: Is the TE Connectivity 9-2176088-8 compatible with the original part?

A: Yes, with consideration for power rating. The 9-2176088-8 is rated at 0.167W (1/6W) versus 0.1W (1/10W) for the original. Mechanical dimensions are nominally equivalent. Verify PCB layout accommodates the slightly reduced height (0.020" versus 0.022").

Q: What does anti-sulfur coating on the Susumu RG1608P-9531-B-T5 provide?

A: Anti-sulfur coating protects the resistor element from sulfur-containing atmospheric contaminants that can degrade thin film resistors in industrial or corrosive environments. This feature is beneficial for applications in harsh operating conditions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the environmental compliance profile of the original RT0603CRE079K53L.
