ERA-6YKD154Z Equivalent & Substitute Parts

Part Overview

The ERA-6YKD154Z is a 150 kOhms ±0.5% metal film chip resistor rated at 0.125W (1/8W) in 0805 (2012 Metric) package format, manufactured by Panasonic Electronic Components. This part is currently obsolete, with 725 units available in new original stock. The ERA-6YKD154Z operates across -55°C to 125°C and features a temperature coefficient of ±100ppm/°C. Due to its obsolete status, identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this specific resistance value and tolerance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-6YKD154Z is determined by the following critical parameters:

• Resistance Value: 150 kOhms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power Rating: 0.125W, 1/8W (exact match required)
• Package Format: 0805 (2012 Metric) (exact match required)
• Operating Temperature Range: Minimum -55°C to 125°C (substitute must meet or exceed)
• RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

The ERA-6AED154V qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While the ERA-6AED154V uses thin film composition with improved temperature coefficient (±25ppm/°C versus ±100ppm/°C) and extended upper operating temperature (155°C versus 125°C), these represent performance enhancements rather than deviations from the required specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-6AED154V is the qualified substitute for the obsolete ERA-6YKD154Z. Both parts meet identical electrical specifications (150 kOhms, ±0.5%, 0.125W) and mechanical requirements (0805 package). The ERA-6AED154V maintains active product status with significantly higher inventory availability (25,182 units versus 725 units), ensuring long-term supply continuity.

The ERA-6AED154V provides enhanced performance characteristics: improved temperature stability (±25ppm/°C versus ±100ppm/°C) and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). Both parts maintain ROHS3 compliance and MSL 1 rating. The ERA-6AED154V includes AEC-Q200 automotive qualification, which does not restrict use in non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AED154V directly replace ERA-6YKD154Z in existing designs?

A: Yes. Both parts share identical resistance (150 kOhms), tolerance (±0.5%), power rating (0.125W), and package format (0805). The ERA-6AED154V meets all electrical and mechanical requirements of the original specification.

Q: What is the difference between metal film and thin film composition?

A: Both are film resistor technologies meeting the same tolerance and power specifications. Thin film (ERA-6AED154V) offers superior temperature coefficient stability (±25ppm/°C versus ±100ppm/°C), resulting in more stable resistance values across temperature variations.

Q: Does the AEC-Q200 rating on ERA-6AED154V affect non-automotive applications?

A: No. AEC-Q200 is an automotive qualification standard. Parts meeting this standard are suitable for all applications, including non-automotive use. The qualification represents additional testing and reliability assurance.

Q: Are there inventory or lead time advantages to using ERA-6AED154V?

A: Yes. ERA-6AED154V is in active production status with 25,182 units in stock, compared to 725 units of the obsolete ERA-6YKD154Z. This ensures reliable availability and shorter lead times for new orders.

Q: Do both parts require identical PCB footprints?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and height (0.024" / 0.60mm maximum seated height). No PCB layout modifications are required.
