Substitute Part Grouping Explanation

Substitute parts for the PRSM2JA1K50 are identified based on strict parametric equivalence. The following criteria determine substitutability:

• Resistance value: 1.5 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 235°C (exact match required)
• Physical dimensions: 0.177" Dia x 0.433" L (exact match required)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected (exact match required)

The RSMF2JA1K50 meets all parametric requirements and is classified as a parametric equivalent within the RSMF series from Stackpole Electronics Inc.

Parameter Comparison

Engineering Selection Recommendations

Both the PRSM2JA1K50 and RSMF2JA1K50 are active production parts from Stackpole Electronics Inc with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory conformance for industrial and commercial applications. The PRSM2JA1K50 currently has higher inventory availability at 927 units compared to 745 units for the RSMF2JA1K50. For applications requiring flame-proof and safety-rated resistors with 2W power dissipation in the 1.5 kOhms range, either part provides equivalent performance across the full operating temperature range of -55°C to 235°C.

Frequently Asked Questions (FAQ)
