Substitute Part Grouping Explanation

Substitution eligibility for RT0603FRE07931RL is determined by the following mandatory parameters:

Resistance Value: Must be 931 Ohms (exact match)
Package / Case: Must be 0603 (1608 Metric) for PCB footprint compatibility
Power Rating: Must be ≥0.1W (1/10W) to ensure thermal capability
Composition: Thin film construction maintains electrical performance characteristics
Operating Temperature Range: Must support -55°C ~ 155°C minimum
Termination Count: Must be 2 terminations for standard resistor function

Substitute parts may differ in tolerance (±0.02% to ±0.5%), temperature coefficient (±5ppm/°C to ±50ppm/°C), manufacturer certifications (AEC-Q200), or power rating (up to 0.167W) while maintaining core electrical and mechanical compatibility.

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions.

RT0603BRD07931RL and RT0603DRD07931RL are YAGEO alternatives within the same RT series, offering improved tolerance (±0.1% and ±0.5% respectively) and reduced temperature coefficient (±25ppm/°C) compared to the main part. Both maintain identical package dimensions and power rating.

ERA-3AEB9310V (Panasonic) provides ±0.1% tolerance and ±25ppm/°C temperature coefficient with Automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability.

RG1608V-9310-P-T1 (Susumu) offers the highest precision tolerance (±0.02%) and lowest temperature coefficient (±5ppm/°C) with Anti-Sulfur and Automotive AEC-Q200 features. Height is reduced to 0.50mm maximum.

RP73PF1J931RBTDF (TE Connectivity) provides higher power rating (0.167W / 1/6W) with ±0.1% tolerance, suitable for applications requiring increased thermal dissipation capacity.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD07931RL replace RT0603FRE07931RL directly?

A: Yes. Both parts share identical 931 Ohms resistance, 0603 package, 0.1W power rating, and -55°C to 155°C operating range. RT0603BRD07931RL offers superior tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between RT0603DRD07931RL and RT0603BRD07931RL?

A: Both are YAGEO thin film resistors with identical package and power rating. RT0603BRD07931RL has ±0.1% tolerance, while RT0603DRD07931RL has ±0.5% tolerance. Temperature coefficient is ±25ppm/°C for both. Selection depends on tolerance requirements of the application.

Q: Is ERA-3AEB9310V suitable for automotive applications?

A: Yes. ERA-3AEB9310V carries Automotive AEC-Q200 certification, qualifying it for automotive-grade applications. It maintains the same 931 Ohms resistance, 0603 package, and 0.1W power rating as the main part.

Q: Why does RG1608V-9310-P-T1 have a lower maximum height?

A: RG1608V-9310-P-T1 has a maximum seated height of 0.50mm compared to 0.55mm for other parts. This reduced height may be relevant for applications with strict PCB clearance constraints. All other mechanical and electrical parameters remain compatible.

Q: Can RP73PF1J931RBTDF be used in place of RT0603FRE07931RL?

A: Yes, with consideration for power rating. RP73PF1J931RBTDF is rated at 0.167W (1/6W), which exceeds the 0.1W requirement of the main part. Package dimensions are 0603 (1608 Metric) with 1.55mm length vs 1.60mm for the main part. This minor dimensional difference is within standard PCB footprint tolerance for 0603 components.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and MSL Level 1 (Unlimited) rating, ensuring compatibility with standard lead-free PCB assembly processes and unrestricted storage conditions.
