Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCC 7752 is determined by the following parameters:

Critical Matching Parameters:

• Voltage Rating: 14V
• Lens Style: Round with Domed Top
• Lens Size: RT-1 1/4
• Type: Incandescent
• Color: Clear
• RoHS Compliance: ROHS3 Compliant

Allowable Variation:

• Lead Style: Wire Terminal (main part) to Radial Bi-Pin (substitute)
• MSCP: 0.3 (main part) to 0.5 (substitute)

The JKL Components Corp. part 7646 qualifies as a direct substitute based on matching voltage, lens specifications, color, and compliance requirements. The lead style differs from wire terminal to radial bi-pin configuration, and the luminous intensity increases from 0.3 to 0.5 MSCP. These variations remain within acceptable substitution parameters for this lamp category.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The VCC 7752 is classified as obsolete. The JKL Components Corp. 7646 is an active product, ensuring continued availability and supply chain reliability for new designs and ongoing production requirements.

Compliance Alignment

Both parts maintain ROHS3 compliance and identical MSL ratings (1 - Unlimited), ensuring compatibility with environmental and moisture sensitivity requirements across applications.

Lead Style Transition

Selection between these parts requires evaluation of circuit board design and socket compatibility. The VCC 7752 utilizes wire terminal leads, while the JKL 7646 employs radial bi-pin configuration. This difference necessitates mechanical and electrical interface verification during component substitution.

Luminous Intensity

The JKL 7646 provides increased MSCP (0.5 versus 0.3), resulting in higher light output. Applications requiring identical brightness levels must account for this parameter difference.

Frequently Asked Questions (FAQ)

Q: Can the JKL 7646 directly replace the VCC 7752 without circuit modification?

A: Both parts share identical voltage rating (14V), lens specifications (RT-1 1/4 round domed top), color (clear), and compliance status (ROHS3). However, the lead style differs: wire terminal versus radial bi-pin. Circuit board socket or terminal configuration must accommodate the bi-pin lead style. Electrical interface compatibility requires verification.

Q: What is the significance of the MSCP difference (0.3 to 0.5)?

A: MSCP (Mean Spherical Candle Power) measures luminous intensity. The JKL 7646 produces approximately 67% greater light output than the VCC 7752. Applications with brightness-sensitive requirements must evaluate whether increased luminosity is acceptable or requires circuit-level compensation.

Q: Are both parts suitable for the same voltage applications?

A: Yes. Both parts are rated for 14V operation and maintain identical voltage specifications, ensuring electrical compatibility in 14V circuits.

Q: What packaging differences exist between these parts?

A: The VCC 7752 packaging specification is not provided. The JKL 7646 is supplied in box packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Which part should be selected for new designs?

A: The JKL Components Corp. 7646 is the appropriate selection for new designs, as it maintains active product status and ensures long-term supply availability. The VCC 7752 obsolete status limits its suitability for ongoing production.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant with identical MSL ratings (1 - Unlimited). The JKL 7646 includes REACH Unaffected status. No compliance barriers exist for substitution.
