ERA-3YHD910V Equivalent & Substitute Parts

Part Overview

The ERA-3YHD910V is a 91 Ohms ±0.5% metal film chip resistor rated at 0.1W (1/10W) in 0603 (1608 Metric) surface mount package, manufactured by Panasonic Electronic Components. This part is currently obsolete, with 623 units available in new original stock. The product operates across a temperature range of -55°C to 125°C and meets ROHS3 compliance requirements.

Finding equivalent substitute parts is necessary due to the obsolete status of the ERA-3YHD910V. Identifying compatible alternatives ensures design continuity and supply chain reliability for applications requiring this specific resistance value and power rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-3YHD910V is determined by strict equivalence across the following critical parameters:

• Resistance value: 91 Ohms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Number of terminations: 2 (exact match required)

The ERA-3AED910V qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While the ERA-3AED910V uses thin film composition (versus metal film in the original) and features automotive AEC-Q200 qualification, these represent functional enhancements rather than deviations from the core substitution criteria. The substitute part maintains the same resistance, tolerance, power rating, and package footprint, ensuring direct compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-3AED910V is the direct substitute for the obsolete ERA-3YHD910V. Both parts maintain identical electrical specifications (91 Ohms ±0.5%, 0.1W) and mechanical compatibility (0603 package, 1.60mm x 0.80mm footprint).

The ERA-3AED910V offers additional advantages: it carries active product status, ensuring long-term availability; it meets AEC-Q200 automotive qualification standards; it provides a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C); and it supports an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). Both parts are ROHS3 compliant with MSL 1 rating.

Selection of the ERA-3AED910V eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs originally specified for the ERA-3YHD910V.

Frequently Asked Questions (FAQ)

Q: Can the ERA-3AED910V be used as a direct replacement for the ERA-3YHD910V?

A: Yes. Both parts share identical resistance (91 Ohms), tolerance (±0.5%), power rating (0.1W), and package (0603). The physical footprint and electrical performance are equivalent, enabling direct substitution in circuit designs.

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

A: Both compositions meet the specified tolerance and temperature coefficient requirements for this application. The thin film construction in the ERA-3AED910V provides a lower temperature coefficient (±25ppm/°C) and extended temperature range, representing a performance enhancement.

Q: Does the AEC-Q200 rating on the ERA-3AED910V affect its use in non-automotive applications?

A: No. AEC-Q200 qualification indicates the part meets automotive reliability standards and is suitable for automotive environments. This certification does not restrict use in general industrial or consumer applications; it only confirms additional qualification testing has been completed.

Q: Are there packaging differences between these parts?

A: The ERA-3YHD910V packaging is not specified in available data. The ERA-3AED910V is supplied in Tape & Reel (TR) format. Both parts use the identical 0603 (1608 Metric) surface mount package with matching dimensions (1.60mm x 0.80mm) and height (0.55mm maximum).

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling procedures for surface mount components apply; no special moisture control measures are required.
