Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERG-1SJ561 is determined by strict equivalence across the following critical parameters:

• Resistance value: 560 Ohms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Metal Oxide Film
• Package: Axial through-hole
• Safety features: Flame proof and safety rated
• Regulatory compliance: ROHS3 compliant

The RSMF1JB560R from Stackpole Electronics Inc meets all these core requirements. While minor variations exist in temperature coefficient and maximum operating temperature, the substitute maintains functional equivalence for the specified resistance, tolerance, power, and safety characteristics.

Parameter Comparison

Engineering Selection Recommendations

The RSMF1JB560R is the direct functional equivalent for ERG-1SJ561 replacement. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute is currently in active production status with confirmed inventory availability (1139 pcs), ensuring supply continuity for applications previously using the obsolete ERG-1SJ561.

The RSMF1JB560R operates within the -55°C to 200°C range, which covers the majority of industrial applications. For systems requiring operation above 200°C up to 235°C, thermal performance characteristics must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can RSMF1JB560R directly replace ERG-1SJ561 in existing designs?

A: Yes. Both parts share identical resistance (560 Ohms), tolerance (±5%), power rating (1W), composition (metal oxide film), and axial package configuration. Both are flame-proof, safety-rated, and ROHS3 compliant.

Q: What are the physical dimension differences?

A: ERG-1SJ561 measures 0.110" diameter × 0.354" length (2.80mm × 9.00mm). RSMF1JB560R measures 0.126" diameter × 0.354" length (3.20mm × 9.00mm). The axial length is identical; the diameter difference is 0.016" (0.40mm).

Q: Are there temperature range limitations with the substitute?

A: RSMF1JB560R operates from -55°C to 200°C, compared to ERG-1SJ561's -55°C to 235°C range. Applications operating above 200°C require thermal analysis to confirm suitability.

Q: What is the temperature coefficient difference?

A: ERG-1SJ561 has ±350ppm/°C; RSMF1JB560R has ±200ppm/°C. The substitute exhibits lower temperature-dependent resistance variation, which is advantageous for precision applications.

Q: Are both parts available for procurement?

A: ERG-1SJ561 is obsolete. RSMF1JB560R is active production with current inventory availability.
