Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GF660 is determined by strict alignment of the following critical parameters:

• Voltage Rating: 8V (exact match required)
• Lens Size: 6mm, T-2 (exact match required)
• Lens Style: Round (exact match required)
• Lead Style: Fuse - 3AG (exact match required)
• Type: Incandescent (exact match required)
• Color: Clear (exact match required)

The GF650 qualifies as a direct substitute based on identical values across all critical parameters. Variance in MSCP (Mean Spherical Candle Power) does not disqualify substitution when all mechanical and electrical parameters align, as MSCP represents luminous intensity output rather than form factor or interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

The GF650 is the manufacturer-recommended substitute for the obsolete GF660. Both components share identical mechanical interfaces, electrical ratings, and environmental compliance profiles. The GF650 maintains active product status with current manufacturing support and inventory availability (1029 pcs in stock versus 851 pcs for the GF660).

The GF650 achieves RoHS3 compliance, providing enhanced regulatory alignment for new designs and long-term supply chain stability. Selection of the GF650 eliminates obsolescence risk while maintaining full form factor and functional compatibility within 8V incandescent lamp applications requiring 6mm T-2 fuse-lead configurations.

Frequently Asked Questions (FAQ)

Q: Can the GF650 be used as a direct replacement for the GF660 in existing designs?

A: Yes. The GF650 provides direct mechanical and electrical compatibility. Identical voltage rating (8V), lens size (6mm T-2), lens style (round), and lead style (fuse - 3AG) ensure socket and circuit compatibility without modification.

Q: What is the significance of the MSCP difference between GF660 and GF650?

A: MSCP measures luminous intensity output. The GF650 produces 0.56 MSCP compared to the GF660's 0.4 MSCP. This represents increased light output and does not affect mechanical fit or electrical interface. Application requirements determine whether increased luminous intensity is acceptable or requires design consideration.

Q: Why is the GF650 recommended over the GF660?

A: The GF660 is classified as obsolete, indicating discontinued manufacturing and limited future availability. The GF650 maintains active status with current production, ensuring long-term supply chain reliability and regulatory compliance (RoHS3).

Q: Are there any packaging or lead configuration differences?

A: No. Both components use identical 3AG fuse lead style and 6mm T-2 form factor. Packaging and mechanical interfaces are fully compatible.

Q: What compliance certifications apply to both parts?

A: Both the GF660 and GF650 maintain REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited). The GF650 additionally achieves RoHS3 compliance, providing enhanced environmental and regulatory alignment.
