Substitute Part Grouping Explanation

Substitute parts for the AT1206DRD07124RL are qualified based on the following criteria:

Core Electrical Parameters (Required Match):

• Resistance value: 124 Ohms
• Package / Case: 1206 (3216 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

Allowable Variations:

• Tolerance: May be equal to or tighter than ±0.5% (±0.1% acceptable)
• Power Rating: May be equal to or greater than 0.25W
• Operating Temperature Range: May be equal to or extended
• Features: Anti-sulfur and AEC-Q200 ratings may be present or absent depending on application requirements

Three substitute parts meet these criteria across different manufacturers and performance tiers.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07124RL (YAGEO RT Series): This part provides tighter tolerance (±0.1% vs ±0.5%) while maintaining identical power rating, temperature coefficient, and operating range. It is suitable for applications requiring improved accuracy. However, it lacks anti-sulfur coating and AEC-Q200 certification. Select this part when tolerance performance is prioritized and automotive qualification is not required.

TNPW1206124RBEEA (Vishay Dale TNPW e3 Series): This part offers the highest power rating (0.52W vs 0.25W), tighter tolerance (±0.1%), extended operating temperature range (-55°C ~ 175°C), and retains anti-sulfur coating and AEC-Q200 certification. It is suitable for applications requiring higher power dissipation capability or extended temperature operation. Physical dimensions are slightly larger (3.20mm L vs 3.10mm L).

ERA-8AEB1240V (Panasonic ERA-8A Series): This part provides tighter tolerance (±0.1%), maintains identical power rating and operating temperature range, and includes AEC-Q200 certification. It lacks anti-sulfur coating. Physical dimensions are slightly larger (3.20mm L vs 3.10mm L, 0.70mm H vs 0.65mm H). Select this part when AEC-Q200 qualification is required with improved tolerance and high inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124RL replace AT1206DRD07124RL in automotive applications?

A: RT1206BRD07124RL is electrically compatible and mechanically interchangeable. However, it lacks AEC-Q200 certification and anti-sulfur coating. Use only in non-automotive or non-corrosive environments where these qualifications are not required.

Q: What is the advantage of TNPW1206124RBEEA over the original part?

A: TNPW1206124RBEEA provides higher power rating (0.52W vs 0.25W), tighter tolerance (±0.1% vs ±0.5%), extended temperature range to 175°C, and retains automotive AEC-Q200 qualification and anti-sulfur coating. Physical dimensions are slightly larger; verify PCB layout compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 Compliant with MSL 1 rating, meeting environmental and moisture sensitivity requirements.

Q: Can ERA-8AEB1240V be used in high-temperature applications?

A: ERA-8AEB1240V operates to 155°C, matching the original part. For applications requiring operation above 155°C, TNPW1206124RBEEA is rated to 175°C.

Q: Are there physical size differences between substitute parts?

A: RT1206BRD07124RL matches original dimensions (3.10mm L × 1.60mm W × 0.65mm H). TNPW1206124RBEEA and ERA-8AEB1240V have slightly larger length (3.20mm) and ERA-8AEB1240V has increased height (0.70mm). Verify PCB footprint and clearance before substitution.

Q: Which substitute part has the best inventory availability?

A: ERA-8AEB1240V has the highest inventory (16152 units), followed by RT1206BRD07124RL (7287 units) and TNPW1206124RBEEA (5903 units).
