ERG-3SJ913 Equivalent & Substitute Parts

Part Overview

The ERG-3SJ913 is a 91 kOhms ±5% 3W axial through-hole resistor manufactured by Panasonic Electronic Components. This metal oxide film resistor features flame-proof and safety characteristics with an operating temperature range of -55°C to 235°C. The product is currently obsolete, making equivalent substitute parts necessary for ongoing circuit maintenance, repair, and redesign applications where this specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERG-3SJ913 are qualified based on the following electrical and mechanical parameters:

• Resistance Value: Must be 91 kOhms
• Tolerance: Must be ±5%
• Composition: Must be Metal Oxide Film
• Package Type: Must be Axial through-hole
• Features: Must include Flame Proof and Safety characteristics
• Operating Temperature Range: Must support -55°C to 235°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status

The substitute parts identified (RSMF5JT91K0 and RSMF5JB91K0) meet all core electrical specifications. Both are manufactured by Stackpole Electronics Inc and maintain the same resistance, tolerance, composition, and operating temperature range. The primary difference is power rating: substitute parts are rated at 5W compared to the original 3W specification. This represents an upgrade in thermal capability while maintaining full electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF5JT91K0 and RSMF5JB91K0 are direct functional equivalents to the ERG-3SJ913. Selection between these two substitute parts depends on procurement and assembly requirements:

RSMF5JT91K0 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes and high-volume production environments.

RSMF5JB91K0 is supplied in Bulk packaging, suitable for manual assembly, repair operations, and lower-volume applications.

Both substitute parts are manufactured by an active supplier with current product status and full ROHS3 compliance. The 5W power rating of the substitutes provides enhanced thermal margin compared to the original 3W specification, with no negative impact on circuit performance. The improved temperature coefficient (±200ppm/°C versus ±300ppm/°C) offers superior stability across the operating temperature range.

Physical dimensions of the substitute parts are slightly larger (0.236" Dia x 0.689" L versus 0.217" Dia x 0.591" L), which must be verified for fit within existing PCB layouts and mechanical enclosures.

Frequently Asked Questions (FAQ)

Q: Can RSMF5JT91K0 and RSMF5JB91K0 be used interchangeably with ERG-3SJ913?

A: Yes. Both substitute parts meet all core electrical specifications: 91 kOhms resistance, ±5% tolerance, metal oxide film composition, axial package type, flame-proof and safety features, and -55°C to 235°C operating temperature range. The 5W power rating represents an upgrade that maintains full compatibility.

Q: What is the difference between RSMF5JT91K0 and RSMF5JB91K0?

A: The electrical and mechanical specifications are identical. The only difference is packaging: RSMF5JT91K0 is supplied in Tape & Reel format for automated assembly, while RSMF5JB91K0 is supplied in Bulk format for manual handling and repair applications.

Q: Will the larger physical dimensions of the substitute parts cause compatibility issues?

A: The substitute parts are 0.019" larger in diameter and 0.098" longer than the original ERG-3SJ913. PCB layout and mechanical clearance must be verified before implementation. If space constraints exist, alternative solutions may be required.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both RSMF5JT91K0 and RSMF5JB91K0 are ROHS3 Compliant, matching the compliance status of the original ERG-3SJ913.

Q: Why do the substitute parts have a lower temperature coefficient?

A: The substitute parts feature ±200ppm/°C compared to the original ±300ppm/°C. This represents improved stability and is not a limitation. The lower temperature coefficient is a performance advantage that does not affect substitution compatibility.

Q: Can I use a lower power-rated resistor as a substitute?

A: No. Substitutes must maintain or exceed the power rating of the original part. Using a lower power rating would create thermal stress and potential failure risk.
