Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RR1220P-2870-D-M are qualified based on the following criteria:

Core Compatibility Parameters:

• Resistance value: 287 Ohms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Number of terminations: 2 (exact match required)

Allowable Variations:

• Tolerance: Substitutes with ±0.1% tolerance are acceptable as they represent improved precision relative to the ±0.5% specification
• Power rating: Substitutes with equal or higher power ratings (0.125W, 0.25W) are acceptable
• Temperature coefficient: Substitutes with ±10ppm/°C or ±25ppm/°C are acceptable
• Operating temperature range: Substitutes with extended upper temperature limits (-55°C ~ 155°C) are acceptable
• Certifications: Automotive AEC-Q200 qualification is an additional feature, not a restriction

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and REACH unaffected status consistent with the main part.

Parameter Comparison

Engineering Selection Recommendations

RN73C2A287RBTDF (TE Connectivity Passive Product)

This substitute provides identical power rating (0.1W) and resistance value (287 Ohms) to the main part while offering improved tolerance (±0.1% versus ±0.5%) and superior temperature coefficient (±10ppm/°C versus ±25ppm/°C). Operating temperature range extends to 155°C. All compliance certifications align with the main part. This option is suitable for applications requiring enhanced precision without power rating modifications.

ERA-6AEB2870V (Panasonic Electronic Components)

This substitute incorporates Automotive AEC-Q200 qualification, indicating suitability for automotive applications. Tolerance improves to ±0.1%, and operating temperature extends to 155°C. Power rating increases to 0.125W (1/8W). All compliance certifications are maintained. This option is appropriate for automotive-grade applications or environments requiring extended temperature performance.

RT0805BRD07287RL (YAGEO)

This substitute offers ±0.1% tolerance and 0.125W power rating with extended operating temperature to 155°C. All compliance certifications are maintained. This option provides balanced performance improvement across tolerance and temperature specifications.

6-2176091-7 (TE Connectivity Passive Product)

This substitute provides the highest power rating (0.25W, 1/4W) among available options with ±0.1% tolerance and extended operating temperature to 155°C. All compliance certifications are maintained. This option is suitable for applications requiring increased power dissipation capability.

Frequently Asked Questions (FAQ)

Q: Can the RR1220P-2870-D-M be replaced with a substitute having ±0.1% tolerance instead of ±0.5%?

A: Yes. Substitutes with ±0.1% tolerance are acceptable replacements. Improved tolerance represents a tighter specification and does not create incompatibility with circuits designed for ±0.5% tolerance.

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

A: Yes. All substitute parts listed are manufactured in 0805 (2012 Metric) package format with identical length and width dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Height variations exist due to different manufacturing processes but remain within acceptable PCB assembly tolerances.

Q: What is the significance of the AEC-Q200 qualification on the ERA-6AEB2870V?

A: AEC-Q200 is an automotive industry qualification standard. The ERA-6AEB2870V meets automotive-grade reliability and performance requirements. This qualification is beneficial for automotive applications but does not restrict use in non-automotive applications.

Q: Can a substitute with higher power rating (0.25W) be used in place of the 0.1W main part?

A: Yes. A higher power rating indicates greater power dissipation capability. Substitutes with equal or higher power ratings are compatible with circuits designed for the original 0.1W specification.

Q: How do temperature coefficient differences affect component selection?

A: Temperature coefficient (±10ppm/°C or ±25ppm/°C) indicates resistance value drift over temperature. Lower values represent better stability. Substitutes with ±10ppm/°C (RN73C2A287RBTDF) provide superior temperature stability compared to the main part's ±25ppm/°C specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts maintain RoHS3 compliance consistent with the main part RR1220P-2870-D-M.

Q: What is the difference between the operating temperature ranges?

A: The main part operates from -55°C to 125°C. All substitute parts extend the upper limit to 155°C, providing 30°C additional high-temperature capability. The lower limit remains -55°C across all parts.

Q: Can the RR1220P-2870-D-M be used interchangeably with substitute parts in existing designs?

A: Yes. All substitute parts share identical resistance value (287 Ohms), package format (0805), and composition (Thin Film). Electrical and mechanical compatibility is maintained. Tolerance and temperature coefficient improvements in substitutes do not create incompatibility with existing circuit designs.
