Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM1819-10PK is determined by strict equivalence across the following critical parameters:

• Voltage Rating: 28V (exact match required)
• Lamp Type: Incandescent (technology class)
• Color: Clear (optical characteristic)
• MSCP: 0.34 (luminous intensity specification)
• Lens Style: Round with Domed Top (mechanical form factor)
• Lens Size: RT-3 1/4 (dimensional specification)
• Lead Style: Miniature Bayonet (electrical connection interface)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Parts meeting all these parameters are classified as direct substitutes. Packaging configuration (10-pack versus bulk) does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The CM1819 (bulk packaging) is a direct functional equivalent to the CM1819-10PK. Both parts are manufactured by VCC and share identical electrical, optical, and mechanical specifications. The primary distinction is packaging configuration: CM1819-10PK is supplied in 10-unit packs, while CM1819 is supplied in bulk quantities.

Both parts carry "discontinued" or "not for new designs" status designations, reflecting their legacy product classification. Both maintain full ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements.

Selection between these parts should be based on procurement quantity requirements and packaging compatibility with existing assembly processes. The CM1819 offers significantly higher inventory availability (3779 Pcs versus 858 Pcs), providing improved supply security for sustained production requirements.

Frequently Asked Questions (FAQ)

Q: Can CM1819 replace CM1819-10PK in existing applications?

A: Yes. Both parts are electrically and mechanically identical. The CM1819 is a direct substitute with identical voltage rating (28V), luminous intensity (0.34 MSCP), lens configuration (round domed top, RT-3 1/4), and lead style (miniature bayonet). Packaging differs only in quantity per unit.

Q: What is the difference between the 10-pack and bulk packaging?

A: CM1819-10PK is supplied in 10-unit packages. CM1819 is supplied in bulk quantities. Functional performance and specifications are identical. Selection depends on procurement volume and assembly line packaging requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both CM1819-10PK and CM1819 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: Why are both parts marked as discontinued or not for new designs?

A: Both parts represent legacy incandescent lamp technology. VCC has classified these as discontinued or not recommended for new product development, though existing inventory remains available for replacement and maintenance applications.

Q: What inventory should I prioritize for procurement?

A: The CM1819 (bulk) offers 3779 Pcs in stock compared to 858 Pcs for CM1819-10PK. For applications requiring sustained supply, the CM1819 provides superior inventory availability.
