RT1206FRE07237KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07237KL is a 237 kOhms ±1% thin film chip resistor in 1206 (3216 Metric) package format, rated for 0.25W power dissipation. This YAGEO component operates across -55°C to 155°C and maintains ROHS3 compliance with unlimited moisture sensitivity rating. The part is currently active in production with 632 units in stock.

Substitute parts are identified when electrical specifications and mechanical compatibility remain within acceptable parameters for the application. Alternative sources provide enhanced tolerance grades or automotive-qualified variants while maintaining the same resistance value, package footprint, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by three core criteria:

Electrical Compatibility: Resistance value must remain 237 kOhms. Tolerance grades may be tighter (lower values) without affecting circuit function. Temperature coefficient specifications must support the same operating range (-55°C ~ 155°C).

Mechanical Compatibility: Package format must be 1206 (3216 Metric). Physical dimensions and termination count (2 terminations) must match or remain within acceptable PCB assembly tolerances.

Regulatory & Environmental Compliance: RoHS3 compliance and MSL rating must be maintained or exceeded. Operating temperature range must cover or exceed the original specification.

The following substitute parts meet all three criteria:

• RT1206DRD07237KL (YAGEO): Tighter tolerance (±0.5%), improved temperature coefficient (±25ppm/°C)
• ERA-8AEB2373V (Panasonic): Highest tolerance grade (±0.1%), automotive AEC-Q200 qualified, improved temperature coefficient (±25ppm/°C)

Parameter Comparison

Engineering Selection Recommendations

RT1206DRD07237KL is suitable for applications requiring improved tolerance control without automotive qualification requirements. The ±0.5% tolerance and ±25ppm/°C temperature coefficient provide enhanced stability compared to the original specification while maintaining identical package compatibility and regulatory compliance.

ERA-8AEB2373V is specified for automotive and mission-critical applications. AEC-Q200 qualification ensures component reliability under automotive environmental stress conditions. The ±0.1% tolerance represents the highest precision grade available in this substitution set. Physical dimensions (0.126" L x 0.063" W vs. 0.122" L x 0.063" W) and maximum seated height (0.028" vs. 0.026") remain within standard PCB assembly tolerances for 1206 packages.

Frequently Asked Questions (FAQ)

Q: Can RT1206DRD07237KL replace RT1206FRE07237KL in any application?

A: Yes. Both components share identical resistance value, power rating, package format, and operating temperature range. The tighter tolerance (±0.5% vs. ±1%) and improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C) make RT1206DRD07237KL functionally superior for precision circuit applications.

Q: What is the primary difference between ERA-8AEB2373V and the YAGEO alternatives?

A: ERA-8AEB2373V carries AEC-Q200 automotive qualification and offers the tightest tolerance grade (±0.1%). Physical dimensions are slightly larger (0.126" L vs. 0.122" L), but remain within standard 1206 package tolerances. This part is specified for automotive and high-reliability applications.

Q: Are there package compatibility concerns when substituting these parts?

A: All three parts use the 1206 (3216 Metric) package with 2 terminations. ERA-8AEB2373V has marginally larger dimensions (0.028" maximum seated height vs. 0.026"), which remains compatible with standard PCB assembly processes and does not affect electrical performance.

Q: Do all substitute parts maintain the same environmental compliance?

A: Yes. All three parts are ROHS3 compliant with MSL rating of 1 (Unlimited). REACH status is unaffected for all variants. No additional environmental qualification or handling procedures are required when substituting between these parts.

Q: Which substitute should be selected for cost optimization?

A: RT1206DRD07237KL offers the best balance of improved specifications and standard industrial availability. ERA-8AEB2373V is selected only when automotive qualification (AEC-Q200) is a design requirement.
