Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206CRE077K87L is determined by the following critical parameters:

• Resistance value: 7.87 kOhms (exact match required)
• Package format: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or greater acceptable)
• Composition: Thin film technology (maintains electrical characteristics)
• Operating temperature range: -55°C to 155°C minimum (equal or greater range acceptable)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The ERA-8AEB7871V qualifies as a substitute part because it maintains identical resistance value, package format, power rating, and composition while meeting all regulatory compliance requirements. Enhanced specifications in tolerance and temperature coefficient represent performance improvements without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206CRE077K87L and ERA-8AEB7871V are active production components with ROHS3 compliance and MSL 1 rating. The ERA-8AEB7871V offers tighter tolerance specification (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), which may provide improved circuit stability in precision applications. The ERA-8AEB7871V carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications where the main part specification does not indicate such qualification. Selection between these parts should be based on application requirements for tolerance precision, temperature stability, and any automotive qualification mandates.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB7871V be used as a direct replacement for RT1206CRE077K87L?

A: Yes. Both parts share identical resistance value (7.87 kOhms), package format (1206), power rating (0.25W), composition (thin film), and operating temperature range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What are the physical dimension differences between these parts?

A: RT1206CRE077K87L dimensions are 0.122" L x 0.063" W (3.10mm x 1.60mm) with maximum seated height of 0.026" (0.65mm). ERA-8AEB7871V dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum seated height of 0.028" (0.70mm). These minor variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Does the tighter tolerance of ERA-8AEB7871V affect circuit compatibility?

A: The ERA-8AEB7871V tolerance of ±0.1% is a subset of the RT1206CRE077K87L tolerance of ±0.25%. This represents improved specification performance and maintains full compatibility with circuits designed for the main part.

Q: What is the significance of AEC-Q200 rating on the ERA-8AEB7871V?

A: AEC-Q200 is an automotive qualification standard. The ERA-8AEB7871V meets this automotive-grade specification, making it suitable for automotive applications. The main part does not specify this qualification.

Q: Are there inventory considerations between these parts?

A: RT1206CRE077K87L has 862 pieces in stock. ERA-8AEB7871V has 5825 pieces in stock. Availability may influence selection based on project timeline requirements.
