Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 48.7 kOhms (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Composition: Thin Film (maintains electrical characteristics)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)

Allowable Variations:

• Tolerance: May be equal or tighter (±1% or better)
• Temperature coefficient: May be equal or lower (±50ppm/°C or better)
• Certifications: May include additional qualifications (e.g., AEC-Q200)

Identified Substitutes:

1. RT1206BRD0748K7L (YAGEO) – Upgrade variant with tighter tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C). Identical package and power rating.

2. ERA-8AEB4872V (Panasonic Electronic Components) – Automotive-qualified variant with AEC-Q200 certification, ±0.1% tolerance, and ±25ppm/°C temperature coefficient. Slight dimensional variation within acceptable mechanical limits.

Parameter Comparison

Engineering Selection Recommendations

RT1206FRE0748K7L (Original): Select for general-purpose applications where ±1% tolerance and standard thin film performance meet circuit specifications. ROHS3 compliance and unlimited moisture sensitivity support standard manufacturing and storage conditions.

RT1206BRD0748K7L (YAGEO Upgrade): Select when tighter tolerance (±0.1%) and improved temperature stability (±25ppm/°C) are required within the same manufacturer ecosystem. Maintains identical package footprint and power rating. Recommended for precision analog circuits requiring enhanced accuracy.

ERA-8AEB4872V (Panasonic Automotive): Select for automotive applications requiring AEC-Q200 qualification. Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient with automotive-grade reliability. Slight dimensional variation (3.20mm L × 1.60mm W vs. 3.10mm L × 1.60mm W) and maximum height (0.70mm vs. 0.65mm) require PCB layout verification for space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0748K7L be used as a direct replacement for RT1206FRE0748K7L?

A: Yes. Both components share identical resistance value, package format, power rating, and operating temperature range. The substitute offers improved tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C), making it functionally superior for the same circuit application.

Q: What are the mechanical differences between ERA-8AEB4872V and the YAGEO variants?

A: ERA-8AEB4872V has slightly larger length (3.20mm vs. 3.10mm) and maximum seated height (0.70mm vs. 0.65mm). These differences remain within standard 1206 package tolerances but require verification in PCB designs with tight component spacing or height restrictions.

Q: Is ERA-8AEB4872V suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification indicates enhanced reliability and stricter manufacturing controls. The component meets all general-purpose requirements and can be used in non-automotive circuits where the additional qualification and performance characteristics provide value.

Q: What determines whether a substitute part is acceptable for my circuit?

A: Substitution eligibility depends on matching the resistance value (48.7 kOhms), package format (1206), power rating (0.25W minimum), and operating temperature range (-55°C ~ 155°C minimum). Tighter tolerance and improved temperature coefficient are always acceptable. Dimensional variations must be verified against PCB layout constraints.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206FRE0748K7L, RT1206BRD0748K7L, and ERA-8AEB4872V are all ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), supporting standard manufacturing and storage without special handling requirements.
