Substitute Part Grouping Explanation

Substitute parts for the R3J1K5 are identified based on strict parametric equivalence within the following criteria:

• Resistance value: 1.5 kOhms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Radial lead
• Temperature coefficient: ±260ppm/°C
• Physical dimensions: 0.438" L x 0.313" W (11.13mm x 7.95mm)
• Height seated (max): 0.469" (11.91mm)
• Features: Flame retardant coating and safety construction

The R3J1K5E qualifies as a parametric equivalent substitute, maintaining identical electrical specifications and mechanical form factor while differing in packaging configuration and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both R3J1K5 and R3J1K5E are active production components from Ohmite's PC-58 series with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and packaging needs:

The R3J1K5E offers ROHS3 compliance and bulk packaging configuration, making it suitable for applications subject to RoHS3 regulatory requirements. The R3J1K5 maintains standard packaging and is appropriate for applications without RoHS3 mandates. Both parts are functionally interchangeable in circuit applications where the specified electrical parameters and physical form factor are required.

Frequently Asked Questions (FAQ)

Q: Can R3J1K5E be used as a direct replacement for R3J1K5?

A: Yes. Both parts maintain identical resistance (1.5 kOhms), tolerance (±5%), power rating (3W), temperature coefficient (±260ppm/°C), and physical dimensions. The primary differences are packaging configuration (bulk vs. standard) and RoHS compliance status.

Q: What is the difference between the packaging configurations?

A: R3J1K5 uses standard packaging while R3J1K5E uses bulk packaging. This distinction affects order quantities and handling procedures but does not impact electrical performance or mechanical fit.

Q: Are there RoHS compliance considerations for substitution?

A: R3J1K5 is RoHS non-compliant while R3J1K5E is ROHS3 compliant. Applications subject to RoHS3 regulatory requirements must use R3J1K5E. Applications without RoHS3 mandates may use either part.

Q: Do the physical dimensions differ between these parts?

A: No. Both parts share identical dimensions: 0.438" L x 0.313" W (11.13mm x 7.95mm) with a maximum seated height of 0.469" (11.91mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: What is the moisture sensitivity level difference?

A: R3J1K5 lists MSL as Not Applicable, while R3J1K5E specifies MSL 1 (Unlimited). This indicates R3J1K5E has no moisture sensitivity restrictions during storage and handling.
