Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT1206DRD07124KL are qualified based on the following criteria:

• Identical resistance value: 124 kOhms
• Compatible package: 1206 (3216 Metric)
• Equal or greater power rating: 0.25W minimum
• Matching operating temperature range: -55°C ~ 155°C
• Thin film composition
• Temperature coefficient: ±25ppm/°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Two substitute parts meet these criteria: RT1206BRD07124KL (YAGEO) and ERA-8AEB1243V (Panasonic Electronic Components). Both maintain the same resistance, package, power rating, and environmental specifications as the original part.

Parameter Comparison

Engineering Selection Recommendations

The AT1206DRD07124KL, RT1206BRD07124KL, and ERA-8AEB1243V are electrically and mechanically interchangeable for applications requiring 124 kOhms thin film resistors in 1206 package with 0.25W power rating and -55°C to 155°C operating range.

RT1206BRD07124KL offers tighter tolerance (±0.1% versus ±0.5%) while maintaining identical electrical and thermal specifications. This substitute is suitable for applications where improved tolerance performance is beneficial and AEC-Q200 automotive qualification is not required.

ERA-8AEB1243V provides AEC-Q200 automotive qualification matching the original part's automotive-grade specification. This substitute is appropriate for automotive and harsh-environment applications requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124KL replace AT1206DRD07124KL in automotive applications?

A: RT1206BRD07124KL is electrically and mechanically compatible and maintains identical operating temperature range and power rating. However, it lacks AEC-Q200 automotive qualification. Use only in non-automotive applications or where automotive qualification is not a design requirement.

Q: What is the difference between AT1206DRD07124KL and ERA-8AEB1243V?

A: Both parts are AEC-Q200 qualified and functionally equivalent. ERA-8AEB1243V has slightly larger physical dimensions (0.126" L x 0.063" W versus 0.122" L x 0.063" W) and maximum seated height (0.028" versus 0.026"). Verify PCB layout compatibility before substitution.

Q: Are all three parts RoHS3 compliant?

A: Yes. AT1206DRD07124KL, RT1206BRD07124KL, and ERA-8AEB1243V are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Which substitute has the best tolerance specification?

A: Both RT1206BRD07124KL and ERA-8AEB1243V offer ±0.1% tolerance, compared to ±0.5% for the original AT1206DRD07124KL.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All three parts share identical operating temperature range of -55°C to 155°C and temperature coefficient of ±25ppm/°C, making them suitable for equivalent thermal performance.
