Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RR0816Q-15R4-D-19R are qualified based on the following substitution criteria:

Primary Matching Parameters:

• Resistance value: 15.4 Ohms (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Number of Terminations: 2 (exact match required)

Compatible Variation Parameters:

• Tolerance: Substitute parts with ±0.1% tolerance are compatible with applications requiring the ±0.5% specification, as tighter tolerance represents enhanced performance
• Power Rating: Substitute parts with equal or higher power ratings (0.063W or greater) are compatible
• Operating Temperature Range: Substitute parts with equal or extended temperature ranges are compatible
• Temperature Coefficient: Substitute parts with equal or lower temperature coefficient values are compatible
• RoHS and MSL Compliance: All substitute parts maintain RoHS3 compliance and MSL 1 rating

All three substitute parts meet these criteria and are direct functional equivalents for the RR0816Q-15R4-D-19R.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are Active status components with full RoHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compliance equivalent to the main part.

RN73C1J15R4BTDF (TE Connectivity): This substitute provides identical power rating (0.063W) with enhanced tolerance specification (±0.1% versus ±0.5%) and superior temperature coefficient (±10ppm/°C). Operating temperature range extends to 155°C. Selection is appropriate for applications requiring tighter tolerance control and extended high-temperature operation within the same power dissipation envelope.

RP73PF1J15R4BTDF (TE Connectivity): This substitute offers increased power rating (0.167W) with enhanced tolerance (±0.1%) and moderate temperature coefficient (±25ppm/°C). Operating temperature range extends to 155°C. Selection is appropriate for applications requiring higher power dissipation capability or thermal margin while maintaining the 0603 package footprint.

RT0603BRD0715R4L (YAGEO): This substitute provides intermediate power rating (0.1W) with enhanced tolerance (±0.1%) and temperature coefficient (±25ppm/°C). Operating temperature range extends to 155°C. REACH Unaffected status provides additional regulatory clarity. Selection is appropriate for applications requiring moderate power increase and improved tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can RN73C1J15R4BTDF replace RR0816Q-15R4-D-19R in all applications?

A: RN73C1J15R4BTDF is a direct functional equivalent with identical 15.4 Ohms resistance, 0603 package, and 0.063W power rating. The ±0.1% tolerance is tighter than the ±0.5% specification, and the ±10ppm/°C temperature coefficient is superior. Extended operating temperature to 155°C provides additional margin. Substitution is valid for all applications where the main part is specified.

Q: What is the difference between the three substitute parts?

A: The primary differences are power rating and temperature coefficient. RN73C1J15R4BTDF maintains the original 0.063W rating with the lowest temperature coefficient (±10ppm/°C). RP73PF1J15R4BTDF offers the highest power rating (0.167W) for applications requiring greater thermal capacity. RT0603BRD0715R4L provides intermediate power rating (0.1W). All three share the same 15.4 Ohms resistance, 0603 package, and ±0.1% tolerance.

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

A: The main part RR0816Q-15R4-D-19R measures 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.020" (0.50mm). Substitute parts RN73C1J15R4BTDF and RP73PF1J15R4BTDF measure 0.061" L x 0.031" W (1.55mm x 0.80mm) with maximum seated height of 0.022" (0.55mm). RT0603BRD0715R4L measures 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.022" (0.55mm). All dimensions remain within 0603 package specifications and are compatible with standard PCB layouts.

Q: Which substitute part should be selected for high-temperature applications?

A: All substitute parts extend the operating temperature range to 155°C compared to the main part's 125°C maximum. RN73C1J15R4BTDF offers the lowest temperature coefficient (±10ppm/°C), making it the optimal choice for temperature-sensitive applications requiring maximum stability across the extended range.

Q: Are all parts RoHS3 compliant?

A: Yes. The main part RR0816Q-15R4-D-19R and all three substitute parts (RN73C1J15R4BTDF, RP73PF1J15R4BTDF, RT0603BRD0715R4L) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can RP73PF1J15R4BTDF be used in place of RR0816Q-15R4-D-19R if the application has higher power requirements?

A: Yes. RP73PF1J15R4BTDF provides 0.167W power rating compared to the main part's 0.063W rating. The higher power rating ensures adequate thermal margin for applications with increased power dissipation. All other electrical parameters (15.4 Ohms resistance, ±0.1% tolerance, 0603 package) remain compatible.

Q: What is the inventory status of substitute parts?

A: RN73C1J15R4BTDF has 647 pieces in stock. RP73PF1J15R4BTDF has 1698 pieces in stock. RT0603BRD0715R4L has 9770 pieces in stock. The main part RR0816Q-15R4-D-19R has 870 pieces in stock.
