ERG-1SJ111 Equivalent & Substitute Parts

Part Overview

The ERG-1SJ111 is a 110 Ohms ±5% 1W through-hole axial resistor manufactured by Panasonic Electronic Components. This metal oxide film resistor features flame-proof and safety characteristics, designed for applications requiring reliable performance across a wide temperature range from -55°C to 235°C. The ERG-1SJ111 is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitute parts for the ERG-1SJ111 are qualified based on the following critical parameters:

• Resistance value: 110 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 1W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package type: Axial (exact match required)
• Features: Flame Proof, Safety (exact match required)
• RoHS compliance: ROHS3 Compliant (maintained)

The substitute parts RSMF1JT110R and RSMF1JB110R, both manufactured by Stackpole Electronics Inc, meet all critical electrical and mechanical parameters. Both parts are active products with current availability, providing reliable alternatives to the obsolete ERG-1SJ111.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF1JT110R and RSMF1JB110R are active products from Stackpole Electronics Inc and serve as direct functional equivalents to the obsolete ERG-1SJ111. Selection between these two substitute parts depends on packaging requirements:

• RSMF1JT110R is supplied in Tape & Reel (TR) format, suitable for automated assembly processes
• RSMF1JB110R is supplied in Bulk packaging, suitable for manual assembly or small-volume applications

Both parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original ERG-1SJ111. The Stackpole substitutes feature an improved temperature coefficient of ±200ppm/°C compared to the original ±350ppm/°C, providing enhanced stability. The operating temperature range of -55°C to 200°C covers the majority of standard industrial applications, though applications requiring operation above 200°C should be evaluated against specific circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can RSMF1JT110R and RSMF1JB110R be used interchangeably with ERG-1SJ111?

A: Yes. Both Stackpole parts meet all critical electrical specifications: 110 Ohms resistance, ±5% tolerance, 1W power rating, metal oxide film composition, and flame-proof safety features. The difference between these two substitute parts is packaging format only.

Q: What is the difference between RSMF1JT110R and RSMF1JB110R?

A: Both parts are electrically identical. RSMF1JT110R is packaged in Tape & Reel format for automated pick-and-place assembly. RSMF1JB110R is packaged in Bulk format for manual handling and smaller production runs.

Q: Are there physical dimension differences between the original and substitute parts?

A: Yes. The ERG-1SJ111 has a diameter of 0.110" (2.80mm), while both Stackpole substitutes have a diameter of 0.126" (3.20mm). The axial length remains 0.354" (9.00mm) for all three parts. Verify PCB layout and component spacing to confirm physical compatibility.

Q: Do the substitute parts maintain compliance certifications?

A: Yes. Both RSMF1JT110R and RSMF1JB110R are ROHS3 compliant and REACH unaffected, matching the compliance status of the original ERG-1SJ111.

Q: What is the temperature coefficient difference, and does it matter?

A: The original ERG-1SJ111 has a temperature coefficient of ±350ppm/°C, while the Stackpole substitutes have ±200ppm/°C. The lower coefficient in the substitutes indicates improved resistance stability across temperature variations, which is beneficial for precision applications.

Q: What is the maximum operating temperature for the substitute parts?

A: Both RSMF1JT110R and RSMF1JB110R operate from -55°C to 200°C. The original ERG-1SJ111 operates to 235°C. For applications requiring operation above 200°C, alternative solutions should be evaluated.
