Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERG-2SJ510 is determined by strict equivalence across the following critical parameters:

• Resistance value: 51 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial through-hole
• 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)
• Flame-proof and safety features
• RoHS3 compliance

The ERG-2SJ510V qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format, which does not affect functional performance in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The ERG-2SJ510V is a direct functional equivalent to the ERG-2SJ510. Both components are manufactured by Panasonic Electronic Components and maintain identical electrical and mechanical specifications. The distinction between these parts is limited to packaging format: the ERG-2SJ510 is supplied in bulk packaging, while the ERG-2SJ510V is supplied in cut tape format.

Both parts carry obsolete product status and ROHS3 compliance certification. Selection between these equivalents should be based on procurement requirements and packaging compatibility with assembly processes. No electrical or thermal performance differences exist between the two variants.

Frequently Asked Questions (FAQ)

Q: Can the ERG-2SJ510V be used as a direct replacement for the ERG-2SJ510?

A: Yes. The ERG-2SJ510V is electrically and mechanically identical to the ERG-2SJ510. Both components feature 51 Ohm resistance, ±5% tolerance, 2W power rating, metal oxide film composition, and identical operating temperature ranges. The only difference is packaging format.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging and cut tape (CT) packaging differ in presentation format for component handling and assembly. Both formats contain identical components with no impact on electrical performance or thermal characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both the ERG-2SJ510 and ERG-2SJ510V are ROHS3 compliant.

Q: What is the operating temperature range for these resistors?

A: Both parts operate across -55°C to 235°C, with a temperature coefficient of ±350ppm/°C.

Q: Why are these parts listed as obsolete?

A: Product status reflects manufacturer classification. Obsolete designation indicates these components are no longer in active production. Availability through authorized distributors may vary.
