Part Overview

The RR1220P-9310-D-M is a 931 Ohms ±0.5% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This surface-mount device is rated for 0.1W (1/10W) power dissipation and operates across the temperature range of -55°C to 125°C. The component is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and is currently in active production status with 980 pieces available in inventory.

Equivalent and substitute parts are identified to address application requirements including higher power ratings, improved tolerance specifications, extended operating temperature ranges, or automotive-grade certifications while maintaining the same resistance value and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RR1220P-9310-D-M is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 931 Ohms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical footprint compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Temperature Coefficient: ±25ppm/°C (thermal stability)
• Number of Terminations: 2 (circuit interface)

Allowable Variation Parameters:

• Tolerance: Can be equal to or tighter than ±0.5% (±0.1% is acceptable)
• Power Rating: Can be equal to or higher than 0.1W (0.25W or 0.125W are acceptable)
• Operating Temperature Range: Can be equal to or extended beyond -55°C ~ 125°C
• RoHS and REACH Compliance: Must maintain or exceed current compliance status

All identified substitute parts maintain the mandatory compatibility parameters while offering improvements in tolerance specification, power handling capability, or operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

1-2176092-5 (TE Connectivity Passive Product)

This substitute provides improved tolerance specification (±0.1% versus ±0.5%) and increased power rating (0.25W versus 0.1W) within the same 0805 package footprint. Operating temperature range extends to 155°C. The component maintains ROHS3 compliance and MSL 1 rating. Height-seated maximum increases to 0.026" (0.65mm), which requires verification against PCB clearance constraints. This option is suitable for applications requiring higher power dissipation or tighter tolerance control.

ERA-6AEB9310V (Panasonic Electronic Components)

This substitute combines improved tolerance (±0.1%), extended operating temperature range (-55°C ~ 155°C), and automotive-grade AEC-Q200 certification. Power rating is 0.125W (1/8W). The component maintains ROHS3 compliance, MSL 1 rating, and REACH Unaffected status. Height-seated maximum is 0.024" (0.60mm). This option is appropriate for automotive applications or systems requiring AEC-Q200 qualified components.

RT0805BRD07931RL (YAGEO)

This substitute offers improved tolerance (±0.1%), extended operating temperature range (-55°C ~ 155°C), and maintains the same power rating as the Panasonic option (0.125W). The component is ROHS3 compliant with MSL 1 rating and REACH Unaffected status. Height-seated maximum is 0.024" (0.60mm). This option provides a cost-effective alternative with equivalent electrical performance to the Panasonic part without automotive certification.

All substitute parts are currently in active production with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the RR1220P-9310-D-M be directly replaced with any of these substitute parts?

A: Direct replacement is possible only if the application circuit accommodates the physical and electrical differences. All substitutes maintain the 0805 package footprint and 931 Ohms resistance value. However, height-seated maximum dimensions vary (0.020" to 0.026"), which may affect PCB clearance. Tolerance improvements (±0.1% versus ±0.5%) and extended temperature ranges are compatible with applications designed for the original part.

Q: What is the primary difference between the three substitute options?

A: The 1-2176092-5 offers the highest power rating (0.25W) but greatest height (0.026"). The ERA-6AEB9310V and RT0805BRD07931RL both provide 0.125W power rating and 0.024" height, with the ERA-6AEB9310V including automotive AEC-Q200 certification. Selection depends on power dissipation requirements, thermal environment, and automotive qualification needs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all identified substitute parts maintain ROHS3 compliance status. The original RR1220P-9310-D-M and all three substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the impact of tolerance improvement from ±0.5% to ±0.1%?

A: Tighter tolerance (±0.1%) reduces resistance value variation across the component population. For a 931 Ohm resistor, ±0.5% tolerance allows variation of ±4.655 Ohms, while ±0.1% tolerance restricts variation to ±0.931 Ohms. This improvement is beneficial in precision analog circuits, measurement applications, or systems with tight impedance matching requirements.

Q: Can the RR1220P-9310-D-M be used in applications requiring AEC-Q200 certification?

A: No. The RR1220P-9310-D-M does not carry AEC-Q200 certification. For automotive applications requiring AEC-Q200 qualification, the ERA-6AEB9310V (Panasonic) is the appropriate substitute.

Q: What is the significance of the extended operating temperature range in substitute parts?

A: The original RR1220P-9310-D-M operates from -55°C to 125°C. All three substitutes extend the upper limit to 155°C. This extended range accommodates applications with higher ambient temperatures or thermal cycling requirements. The temperature coefficient remains constant at ±25ppm/°C across all options.

Q: Are there any height clearance concerns when substituting these parts?

A: Yes. The original RR1220P-9310-D-M has a maximum seated height of 0.020" (0.50mm). The 1-2176092-5 increases to 0.026" (0.65mm), while ERA-6AEB9310V and RT0805BRD07931RL are 0.024" (0.60mm). PCB layout with low-profile components or confined spaces may require height verification before substitution.

Q: Which substitute offers the best overall performance upgrade?

A: Selection depends on application requirements. The 1-2176092-5 provides maximum power handling (0.25W). The ERA-6AEB9310V provides automotive certification with extended temperature range. The RT0805BRD07931RL provides equivalent performance to the Panasonic part without automotive certification. All three improve tolerance specification compared to the original part.
