Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805DRD07124RL are qualified based on the following criteria:

• Resistance Value: All substitutes maintain 124 Ohms nominal resistance
• Package Compatibility: All substitutes use 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm)
• Composition: All substitutes are thin film resistors
• Temperature Coefficient: All substitutes maintain ±25ppm/°C
• Operating Temperature Range: All substitutes support -55°C minimum; upper limit ranges from 155°C to 175°C
• RoHS & Compliance: All substitutes are ROHS3 compliant with MSL 1 rating
• Tolerance Upgrade Path: Substitutes with ±0.1% tolerance provide tighter tolerance than the original ±0.5%
• Power Rating Variations: Substitutes range from 0.125W to 0.26W, accommodating higher power dissipation requirements
• Automotive Qualification: Select substitutes carry AEC-Q200 certification for automotive applications

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Same Tolerance & Power Rating) RT0805BRD07124RL from YAGEO provides identical electrical and mechanical specifications to the original part with improved tolerance (±0.1% vs ±0.5%). Both components are active products with equivalent inventory availability.

Higher Power Dissipation Applications 3-2176091-3 from TE Connectivity Passive Product doubles the power rating to 0.25W while maintaining ±0.1% tolerance and identical package dimensions. This substitution is appropriate when thermal margin or higher current handling is required.

Automotive Applications with AEC-Q200 Certification ERA-6AEB1240V (Panasonic) and RG2012P-1240-B-T5 (Susumu) both carry AEC-Q200 automotive qualification with ±0.1% tolerance and 0.125W power rating. RG2012P-1240-B-T5 includes anti-sulfur protection. These substitutes are required for automotive-grade designs.

Extended Temperature Range & Enhanced Reliability TNPW0805124RBEEA from Vishay Dale extends the operating temperature range to 175°C (vs 155°C), provides 0.26W power rating, includes anti-sulfur and moisture-resistant features, and carries AEC-Q200 certification. This part is suitable for high-reliability and extended-temperature applications.

Product Status & Compliance All substitute parts maintain active product status and ROHS3 compliance. MSL 1 rating (Unlimited) is consistent across all options, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07124RL directly replace RT0805DRD07124RL? A: Yes. Both parts share identical package dimensions (0805), resistance value (124 Ohms), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). RT0805BRD07124RL offers tighter tolerance (±0.1% vs ±0.5%), making it a direct upgrade.

Q: When should I use 3-2176091-3 instead of the original part? A: Use 3-2176091-3 when your circuit requires higher power dissipation capability. Its 0.25W rating provides double the power handling of the 0.125W original part, while maintaining the same 0805 package footprint and ±0.1% tolerance.

Q: What is the difference between ERA-6AEB1240V and RG2012P-1240-B-T5? A: Both are AEC-Q200 automotive-qualified 0805 resistors with 124 Ohms and ±0.1% tolerance. RG2012P-1240-B-T5 includes anti-sulfur protection and has a slightly lower maximum seated height (0.020" vs 0.024"). Select RG2012P-1240-B-T5 for environments with sulfur exposure risk.

Q: Is TNPW0805124RBEEA compatible with the original design? A: Yes, with enhanced capabilities. TNPW0805124RBEEA maintains the 0805 package and 124 Ohm resistance but offers extended temperature range (-55°C ~ 175°C), higher power rating (0.26W), anti-sulfur protection, and moisture-resistant features. It is a suitable upgrade for high-reliability applications.

Q: Do all substitute parts have the same MSL rating? A: Yes. All parts listed, including the original RT0805DRD07124RL, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during standard storage and handling conditions.

Q: Can I use these substitutes in automotive applications? A: ERA-6AEB1240V, RG2012P-1240-B-T5, and TNPW0805124RBEEA carry AEC-Q200 certification and are suitable for automotive applications. RT0805BRD07124RL and 3-2176091-3 do not carry automotive qualification; verify application requirements before selection.

Q: What is the maximum operating temperature for each substitute? A: RT0805DRD07124RL, RT0805BRD07124RL, 3-2176091-3, ERA-6AEB1240V, and RG2012P-1240-B-T5 all support -55°C ~ 155°C. TNPW0805124RBEEA extends to -55°C ~ 175°C, providing additional thermal margin for high-temperature environments.
