Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 3.65 kOhms (exact match required)
• Package format: 1206 (3216 Metric)
• Power rating: 0.25W minimum
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance
• MSL 1 rating

Allowable Variations:

• Tolerance: May be equal to or tighter than ±1%
• Temperature coefficient: May be equal to or lower than ±50ppm/°C
• Manufacturer: Different manufacturers permitted if all mandatory parameters met
• Certifications: Additional certifications (e.g., AEC-Q200) permitted

The two identified substitutes meet all mandatory compatibility parameters while offering enhanced tolerance specifications (±0.1% vs. ±1%) and improved temperature stability (±25ppm/°C vs. ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD073K65L (YAGEO): Direct upgrade within the same manufacturer series. Provides tighter tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C) while maintaining identical package dimensions and electrical ratings. Suitable for applications requiring enhanced precision without automotive qualification requirements. Higher inventory availability (6753 units) supports supply chain continuity.

ERA-8AEB3651V (Panasonic): Cross-manufacturer substitute with AEC-Q200 automotive qualification. Delivers equivalent tolerance and temperature stability improvements as the YAGEO upgrade option. Dimensions vary slightly (0.126" L vs. 0.122" L; 0.028" H vs. 0.026" H maximum seated height), requiring PCB layout verification for space-constrained applications. Highest inventory availability (10383 units) and automotive-grade certification support mission-critical or automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD073K65L replace RT1206FRE073K65L in any application?

A: Yes. Both parts share identical resistance, power rating, package format, and operating temperature range. The substitute offers superior tolerance and temperature coefficient specifications, making it suitable for all applications where the original part functions.

Q: What is the significance of the ±0.1% tolerance in the substitute parts?

A: The substitute parts maintain resistance values within ±0.1% of the nominal 3.65 kOhms specification, compared to ±1% for the main part. This tighter tolerance reduces circuit performance variation and is beneficial in precision analog circuits, measurement instrumentation, and feedback networks where resistor accuracy directly impacts system performance.

Q: Is ERA-8AEB3651V suitable for non-automotive applications?

A: Yes. AEC-Q200 certification indicates the part meets automotive reliability standards but does not restrict use in non-automotive applications. The part is fully compatible with any circuit requiring a 3.65 kOhms 1206 thin film resistor.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist. ERA-8AEB3651V dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.028" maximum seated height, compared to 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.026" maximum seated height for the YAGEO parts. Verify PCB layout clearances for space-constrained designs before substitution.

Q: Which substitute part should be selected for maximum inventory availability?

A: ERA-8AEB3651V offers the highest inventory level at 10383 units, followed by RT1206BRD073K65L at 6753 units. Selection should prioritize application requirements (automotive qualification, tolerance specifications) over inventory quantity alone.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206FRE073K65L, RT1206BRD073K65L, and ERA-8AEB3651V are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for commercial and industrial applications.
