Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERG-2SJ151 is determined by strict equivalence across the following critical parameters:

• Resistance value: 150 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial leads
• Temperature coefficient: ±350ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.157" Dia x 0.472" L (4.00mm x 12.00mm)
• Safety and flame proof characteristics

The ERG-2SJ151V qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format: the main part is supplied in standard packaging, while the substitute is available in Cut Tape (CT) format.

Parameter Comparison

Engineering Selection Recommendations

Both the ERG-2SJ151 and ERG-2SJ151V meet identical electrical and mechanical specifications. Selection between these parts is determined by procurement and assembly requirements:

The ERG-2SJ151V in Cut Tape (CT) format is suitable for automated assembly processes and high-volume production environments where tape-and-reel packaging provides operational efficiency.

The ERG-2SJ151 in standard packaging is appropriate for manual assembly, prototyping, or applications where packaging format does not impact assembly methodology.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The obsolete product status of both variants necessitates verification of long-term availability through component suppliers.

Frequently Asked Questions (FAQ)

Q: Can ERG-2SJ151V be used as a direct replacement for ERG-2SJ151?

A: Yes. The ERG-2SJ151V is electrically and mechanically equivalent. Both parts share identical resistance, tolerance, power rating, temperature characteristics, and physical dimensions. The difference is packaging format only.

Q: What is the difference between standard packaging and Cut Tape (CT) format?

A: Cut Tape (CT) packaging supplies components on continuous tape suitable for automated pick-and-place assembly equipment. Standard packaging is typically used for manual assembly or smaller quantity applications. Electrical performance is identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory status is equivalent.

Q: Why is the product status listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. Existing inventory may be available through authorized distributors, but long-term availability cannot be guaranteed. Procurement planning should account for this status.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. Axial lead configuration and physical dimensions are identical, ensuring mechanical fit in through-hole mounting positions.
