Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE072K55L are qualified based on the following criteria:

• Identical resistance value: 2.55 kOhms
• Identical package format: 1206 (3216 Metric)
• Identical power rating: 0.25W
• Identical composition: Thin Film
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS3 compliance and MSL rating
• Tolerance equal to or tighter than ±1%
• Temperature coefficient equal to or better than ±50ppm/°C

Two substitute parts meet these criteria: RT1206BRD072K55L (YAGEO) and ERA-8AEB2551V (Panasonic Electronic Components). Both offer improved tolerance specifications (±0.1%) and superior temperature coefficient performance (±25ppm/°C) compared to the main part.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD072K55L is a direct upgrade within the YAGEO RT series, offering tighter tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and compliance certifications. This part is suitable for applications requiring enhanced precision without automotive qualification requirements.

ERA-8AEB2551V provides equivalent electrical performance to RT1206BRD072K55L with the addition of AEC-Q200 automotive qualification. This part is specified for automotive and high-reliability applications where automotive-grade certification is mandatory. Physical dimensions show minor variation (0.126" L x 0.063" W versus 0.122" L x 0.063" W), with maximum seated height of 0.028" versus 0.026", which must be verified against PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD072K55L be used as a direct replacement for RT1206FRE072K55L?

A: Yes. Both parts share identical resistance, power rating, package format, operating temperature range, and compliance certifications. RT1206BRD072K55L offers superior tolerance and temperature coefficient specifications, making it a compatible upgrade.

Q: What is the primary difference between RT1206BRD072K55L and ERA-8AEB2551V?

A: Both parts provide identical electrical specifications (2.55 kOhms ±0.1%, ±25ppm/°C). ERA-8AEB2551V includes AEC-Q200 automotive qualification and has slightly larger physical dimensions (0.126" L x 0.028" H versus 0.122" L x 0.026" H). Select ERA-8AEB2551V for automotive applications; select RT1206BRD072K55L for standard industrial applications.

Q: Are there any PCB layout considerations when substituting with ERA-8AEB2551V?

A: ERA-8AEB2551V has a maximum seated height of 0.028" compared to 0.026" for the original part. Verify that PCB clearance and component placement allow for this 0.002" height difference. Length and width dimensions are also slightly larger (0.126" x 0.063" versus 0.122" x 0.063"), requiring confirmation of footprint compatibility.

Q: Do all three parts maintain the same moisture sensitivity rating?

A: Yes. All three parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute part should be selected for cost optimization?

A: RT1206BRD072K55L offers the best cost-to-performance ratio for non-automotive applications, providing tighter tolerance and improved temperature coefficient at lower cost than the AEC-Q200 qualified ERA-8AEB2551V.
