Key Parameters

Substitute Part Grouping Explanation

Substitution of the RR0816Q-64R9-D-79R is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 64.9 Ohms (exact match required)
• Package form factor: 0603 (1608 Metric) (exact match required)
• Composition: Thin film technology (exact match required)

Upgrade Criteria for Substitute Parts: Substitute components listed below maintain identical resistance, package, and composition specifications while offering one or more of the following improvements:

• Tighter tolerance (±0.1% versus ±0.5%)
• Lower temperature coefficient (±10ppm/°C to ±25ppm/°C versus ±50ppm/°C)
• Extended operating temperature range (-55°C to 155°C versus -55°C to 125°C)
• Higher power rating (0.1W or 0.167W versus 0.063W)
• Enhanced automotive qualification (AEC-Q200)

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and 2-termination configuration.

Frequently Asked Questions (FAQ)

Q: Can the RR0816Q-64R9-D-79R be replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts maintain the same 64.9 Ohms resistance value, 0603 (1608 Metric) package form factor, and thin film composition. They are electrically and mechanically compatible for direct substitution on PCB layouts designed for the original component.

Q: What is the primary difference between the main part and the substitute options?

A: The main part (RR0816Q-64R9-D-79R) has a tolerance of ±0.5% and temperature coefficient of ±50ppm/°C. All substitute parts offer tighter tolerance (±0.1%) and lower temperature coefficients (±10ppm/°C to ±25ppm/°C), resulting in improved accuracy and reduced temperature-related drift.

Q: Which substitute part should be selected for automotive applications?

A: The ERA-3AEB64R9V (Panasonic) is qualified to AEC-Q200 automotive standard and is the appropriate selection for automotive applications. This part also offers extended temperature range (-55°C to 155°C) and improved tolerance specifications.

Q: Are there any physical dimension differences between the main part and substitutes?

A: All parts use the 0603 (1608 Metric) package. Minor variations exist in seated height (0.50mm for the main part versus 0.55mm for most substitutes) and length dimensions (1.60mm for main and RT0603BRD0764R9L versus 1.55mm for RN73 and RP73 series). These variations are within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: What is the significance of the temperature coefficient specification?

A: Temperature coefficient indicates how much the resistance value changes with temperature. The main part has ±50ppm/°C, while substitutes range from ±10ppm/°C to ±25ppm/°C. Lower values indicate better stability across the operating temperature range, which is critical for precision analog circuits and temperature-sensitive applications.

Q: Can the substitute parts handle higher power dissipation than the original?

A: Yes. The main part is rated for 0.063W (1/16W). Substitute options include ERA-3AEB64R9V and RT0603BRD0764R9L at 0.1W (1/10W), and RP73PF1J64R9BTDF at 0.167W (1/6W). Higher power ratings provide additional thermal margin in applications with elevated power dissipation requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original RR0816Q-64R9-D-79R.

Q: What is the difference between the two TE Connectivity options (RN73C1J64R9BTDF and RP73PF1J64R9BTDF)?

A: The RN73C1J64R9BTDF maintains the original 0.063W power rating with the lowest temperature coefficient (±10ppm/°C). The RP73PF1J64R9BTDF offers higher power rating (0.167W) with a temperature coefficient of ±25ppm/°C. Selection depends on whether power handling or temperature stability is the primary design requirement.

Q: Is inventory availability a factor in part selection?

A: Inventory levels vary among substitutes. The RT0603BRD0764R9L (YAGEO) has the highest stock level at 10,762 units, followed by ERA-3AEB64R9V (Panasonic) at 12,161 units. The TE Connectivity options have lower stock levels (1,145 and 1,117 units respectively). Availability should be considered for high-volume production requirements.
