Equivalent & Substitute Parts for CRCW080591R0JNEBC

Part Overview

The CRCW080591R0JNEBC is a 91 Ohm, 5% tolerance, 1/8W (0.125W) chip resistor manufactured by Vishay Dale in 0805 (2012 Metric) package format. This thick film resistor is currently active in production and widely used in general-purpose electronic applications requiring precision resistive elements in compact surface-mount form factors.

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or when design requirements favor alternative manufacturers with superior availability or enhanced material properties such as moisture resistance.

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW080591R0JNEBC is determined by strict equivalence across the following critical parameters:

Resistance Value: 91 Ohms (exact match required)
Tolerance: ±5% (exact match required)
Power Rating: 0.125W / 1/8W (exact match required)
Package Format: 0805 (2012 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature Coefficient: ±200ppm/°C (exact match required)
Operating Temperature Range: -55°C to 155°C (exact match required)
RoHS Compliance: ROHS3 Compliant (minimum requirement)
MSL Rating: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Secondary considerations include product status, packaging format (Tape & Reel vs. Cut Tape), and enhanced features such as moisture resistance.

Engineering Selection Recommendations

Primary Selection: CRCW080591R0JNEBC (Vishay Dale)

The original Vishay Dale part maintains active production status and represents the baseline specification. Selection is appropriate for standard applications where supply availability is adequate.

Direct Substitute: CR0805-JW-910ELF (Bourns Inc.)

The Bourns CR0805-JW-910ELF is functionally equivalent with identical electrical specifications and meets all substitution criteria. This part offers enhanced moisture resistance as an additional material property and maintains active product status. The maximum seated height of 0.024" (0.60mm) matches the original specification exactly. This part is suitable for direct replacement in all applications compatible with the CRCW080591R0JNEBC.

Alternative Substitute: MCR10ERTJ910 (Rohm Semiconductor)

The Rohm MCR10ERTJ910 meets all electrical and mechanical substitution requirements with identical resistance, tolerance, power rating, and temperature characteristics. However, this part is discontinued at DiGi Electronics and carries a maximum seated height of 0.026" (0.65mm), which is 0.002" (0.05mm) higher than the original specification. Selection of this part is appropriate only when space constraints do not restrict the additional height and when supply through alternative distribution channels is confirmed.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTJ910 be used in applications with tight height constraints?

A: The MCR10ERTJ910 has a maximum seated height of 0.026" (0.65mm) compared to 0.024" (0.60mm) for the CRCW080591R0JNEBC. Applications with PCB clearance specifications tighter than 0.026" (0.65mm) require verification before substitution.

Q: What is the advantage of CR0805-JW-910ELF over the original part?

A: The CR0805-JW-910ELF incorporates moisture-resistant thick film construction while maintaining identical electrical specifications and seated height. This feature provides enhanced reliability in humid or moisture-prone environments without compromising mechanical fit.

Q: Are all three parts electrically interchangeable?

A: Yes. All three parts share identical resistance (91 Ohms), tolerance (±5%), power rating (0.125W), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 155°C). Electrical performance is equivalent across all applications.

Q: What packaging formats are available for these parts?

A: CRCW080591R0JNEBC is supplied in Tape & Reel (TR) format. MCR10ERTJ910 is available in Cut Tape (CT) & Digi-Reel® format. CR0805-JW-910ELF is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume specifications.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant and carry MSL Rating 1 (Unlimited), meeting current environmental and reliability standards.
