Equivalent & Substitute Parts for VCC 3149 Incandescent Lamp

Part Overview

The VCC 3149 is an incandescent lamp designed for 5V applications, featuring a clear round lens with domed top and bi-pin radial lead configuration. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

The primary reason for identifying alternatives is the obsolete product status of the VCC 3149. While inventory remains available, long-term availability cannot be assured. Substitute parts must maintain electrical and mechanical compatibility to ensure proper operation within existing circuit designs.

Key Parameters

Parameter	Value	Significance for Substitution
Voltage Rating	5V	Critical electrical parameter; substitute must match exactly
Type	Incandescent	Defines lamp technology and operational characteristics
Color	Clear	Optical property; must match for consistent light output
MSCP (Mean Spherical Candle Power)	0.15	Luminous intensity specification; determines brightness equivalence
Lens Style	Round with Domed Top	Optical and mechanical form factor
Lens Size	RT-1 3/4, 6mm	Physical dimension; affects mechanical fit
Lead Style	Radial - Bi-Pin .125	Electrical connection and mechanical mounting interface
RoHS Status	ROHS3 Compliant	Environmental and regulatory compliance requirement

Substitute Part Grouping Explanation

Substitute part identification for the VCC 3149 is based on strict equivalence across the following critical parameters:

Electrical Parameters:

Voltage Rating: 5V (exact match required)
MSCP: 0.15 (luminous intensity specification)

Optical Parameters:

Type: Incandescent
Color: Clear
Lens Style: Round with Domed Top
Lens Size: RT-1 3/4, 6mm

Mechanical Parameters:

Lead Style: Radial - Bi-Pin .125 (connection interface)

Compliance Parameters:

RoHS3 Compliant status

The substitute part JKL Components Corp. 2203 shares all critical electrical and optical parameters with the VCC 3149. The primary difference is the lead style configuration: the 2203 uses wire terminal leads instead of bi-pin radial leads. This difference represents a mechanical interface change that requires evaluation for specific application compatibility.

Engineering Selection Recommendations

VCC 3149 Selection Criteria:

Current inventory: 939 pieces available
Product Status: Obsolete
Suitable for applications where existing bi-pin radial lead sockets are present and immediate availability is required
RoHS3 compliance confirmed

JKL 2203 Selection Criteria:

Current inventory: 1,106 pieces available
Product Status: Active
Electrical and optical specifications identical to VCC 3149
Lead style differs: wire terminal configuration instead of bi-pin radial
RoHS3 compliance confirmed
REACH Unaffected status documented

Selection Logic: The JKL 2203 is electrically and optically equivalent to the VCC 3149. Both components deliver identical voltage rating (5V), luminous intensity (0.15 MSCP), optical properties (clear, round domed lens), and regulatory compliance (RoHS3). The active product status of the JKL 2203 provides assurance of continued availability for future procurement cycles.

The mechanical difference in lead style (wire terminal versus bi-pin radial) is the primary consideration for substitution feasibility. Applications utilizing bi-pin sockets require either socket adaptation or circuit redesign to accommodate wire terminal leads. Applications with wire terminal connections can directly implement the JKL 2203 without modification.

Frequently Asked Questions (FAQ)

Q: Can the JKL 2203 directly replace the VCC 3149 in existing designs?

A: Electrical and optical compatibility is confirmed. Mechanical compatibility depends on the connection interface. If the existing design uses bi-pin radial sockets, the wire terminal leads of the JKL 2203 require socket modification or circuit redesign. If the design uses wire terminal connections, direct substitution is feasible.

Q: Are the luminous output characteristics identical?

A: Yes. Both components specify 0.15 MSCP (Mean Spherical Candle Power), confirming identical luminous intensity output.

Q: What is the voltage operating range for both components?

A: Both components are rated for 5V operation. Voltage rating is the specified parameter provided; operating range data is not included in the component specifications.

Q: Are both components RoHS compliant?

A: Yes. Both the VCC 3149 and JKL 2203 are ROHS3 compliant. The JKL 2203 additionally documents REACH Unaffected status.

Q: Why is the VCC 3149 classified as obsolete?

A: Product status is determined by manufacturer designation. The VCC 3149 is listed as obsolete by the manufacturer. The JKL 2203 maintains active status, indicating ongoing manufacturer support and availability.

Q: What packaging is provided for each component?

A: VCC 3149 packaging is specified as "-" (not detailed in available documentation). JKL 2203 is supplied in box packaging.

Q: Are there any other substitute options available?

A: Based on the provided substitute list, the JKL 2203 is the identified equivalent part. No additional substitutes are documented.
