Substitute Part Grouping Explanation

Substitute parts for the 5855215 are qualified based on the following critical parameters that determine functional compatibility:

• Base Type: Miniature Bayonet (BA9S)
• Size / Dimension: T - 3 1/4
• Color: Red
• Wavelength: 660nm
• Voltage - Forward (Vf) (Typ): 28V
• Millicandela Rating: 560mcd
• Configuration: Single

All substitute parts maintain identical electrical and mechanical specifications to ensure direct replacement capability in existing circuits and mechanical assemblies. Substitute parts are grouped by product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The primary substitute for the obsolete 5855215 is the 5855215F, which maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The 5855215F is the direct functional equivalent with improved regulatory compliance.

The 5855225F and 5855256F are parametric equivalents that provide identical performance characteristics across all critical electrical and mechanical parameters. These parts are suitable for applications where the base product number differs but functional requirements remain unchanged. All three substitute parts (5855215F, 5855225F, 5855256F) are active products with ROHS3 compliance, providing long-term availability and regulatory alignment compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 5855215F directly replace the obsolete 5855215?

A: Yes. The 5855215F maintains identical electrical specifications (28V forward voltage, 660nm wavelength, 560mcd rating), mechanical form factor (T-3 1/4, BA9S base), and configuration (single red LED). The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between 5855215F, 5855225F, and 5855256F?

A: All three parts are parametric equivalents with identical electrical and mechanical specifications. The differences are in base product numbers (5855215, 5855225, 5855256) and packaging designations. All three are active products with ROHS3 compliance and equivalent performance characteristics.

Q: Are there packaging differences between substitute parts?

A: The 5855215, 5855215F, 5855225F, and 5855256F are all available in bulk packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: Is the 5855215F suitable for new designs?

A: Yes. The 5855215F is an active product with ROHS3 compliance, making it appropriate for new designs requiring 28V red LED indicator lamps with BA9S base and T-3 1/4 form factor.

Q: What inventory levels are available for substitute parts?

A: Current inventory includes 930 pcs of 5855215F, 970 pcs of 5855225F, and 1224 pcs of 5855256F in new original condition.
