Key Parameters

Substitute Part Grouping Explanation

Substitution of the 18626130 requires evaluation of the following critical parameters that determine functional equivalence:

Voltage Compatibility: The main part operates at 130VAC. Substitute parts must operate at compatible voltage levels to ensure proper circuit integration and prevent component failure.

Base Type and Mechanical Fit: The bayonet base configuration is essential for physical installation. Substitute parts must feature compatible base types to ensure proper socket engagement.

Color and Wavelength: Red color specification at 630nm wavelength defines the optical output. Substitute parts must maintain red color output within acceptable wavelength ranges.

LED Configuration: The three-round LED configuration (3 x 120mcd) establishes the light output profile. Substitute parts must provide equivalent or superior luminous intensity.

Form Factor: The T-3 1/4 size dimension constrains physical envelope. Substitute parts must fit within equivalent spatial constraints.

Compliance and Certifications: RoHS3 compliance and REACH unaffected status are regulatory requirements. Substitute parts must maintain equivalent compliance levels.

The substitute part identified (SSP-3MB96U12G) differs significantly in voltage specification (12V versus 130VAC), base type (Miniature Bayonet BA9S versus Bayonet), and form factor, indicating this part is not a direct functional substitute for the 18626130 in its original application context.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Assessment: The SSP-3MB96U12G does not qualify as a direct substitute for the 18626130 due to fundamental incompatibilities in voltage specification and base type. The 18626130 operates at 130VAC with a standard bayonet base, while the SSP-3MB96U12G operates at 12V with a miniature bayonet (BA9S) base. These differences preclude direct socket compatibility and circuit integration.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent product categories. Both parts feature unlimited moisture sensitivity level (MSL 1), indicating robust environmental tolerance.

Product Status Consideration: The 18626130 is classified as obsolete, while the SSP-3MB96U12G maintains active product status. Active status indicates ongoing manufacturer support, availability, and compliance with current standards.

Application Context: Substitution decisions must account for the specific circuit voltage and socket configuration of the target application. The 130VAC specification of the 18626130 indicates integration into AC-powered indicator light systems, while the 12V specification of the SSP-3MB96U12G indicates DC-powered applications. These represent distinct application domains requiring separate component selection strategies.

Frequently Asked Questions (FAQ)

Q: Can the SSP-3MB96U12G directly replace the 18626130 in existing fixtures?

A: No. The SSP-3MB96U12G operates at 12V with a miniature bayonet (BA9S) base, while the 18626130 operates at 130VAC with a standard bayonet base. Physical socket incompatibility and voltage mismatch prevent direct replacement.

Q: What are the critical parameters that determine substitution compatibility for the 18626130?

A: Voltage specification (130VAC), base type (bayonet), color (red), wavelength (630nm), and form factor (T-3 1/4) are the primary parameters defining substitution compatibility. Any substitute part must match these specifications to ensure functional equivalence.

Q: Why is the wavelength difference between 630nm and 626nm significant?

A: Both wavelengths fall within the red spectrum and are visually equivalent for indicator light applications. The 4nm difference represents normal manufacturing variation within the red color category and does not constitute a functional incompatibility.

Q: What does the obsolete status of the 18626130 mean for component sourcing?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. Active alternative products should be evaluated for new designs or system upgrades.

Q: Are there compliance differences between the two parts?

A: No. Both parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, and unlimited moisture sensitivity level (MSL 1). Regulatory requirements are equivalent.

Q: What is the significance of the millicandela rating difference (120mcd versus 12800mcd)?

A: The SSP-3MB96U12G delivers significantly higher luminous intensity (12800mcd) compared to the 18626130 (120mcd). This represents a 100-fold increase in light output. Application requirements determine whether higher intensity is acceptable or problematic for the target system.

Q: Can the 18626130 be used in 12V applications?

A: No. The 18626130 is rated for 130VAC operation. Applying 12V would result in insufficient forward voltage and non-functional operation. Voltage specifications must be strictly observed.
