NAG107PB Equivalent & Substitute Parts

Part Overview

The NAG107PB is a 7-segment LED display module manufactured by Stanley Electric Co, featuring a single green character with 1.00" digit height in a 14-DIP package configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs, repairs, and production continuity. The display operates as a common anode device with a forward voltage of 4.4V and test current of 20mA, suitable for numeric and alphanumeric display applications requiring standard brightness levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NAG107PB is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Display Type: 7-Segment configuration
• Number of Characters: Single character (1)
• Digit/Alpha Size: 1.00" (25.40mm)
• Color: Green
• Common Pin Configuration: Common Anode
• Package / Case: 14-DIP
• Physical Dimensions: 1.299" H x 0.898" W x 0.354" D (33.00mm x 22.80mm x 9.00mm)
• Wavelength - Peak: 565nm (green spectrum)

Allowable Electrical Variation Parameters:

• Voltage - Forward (Vf): Within ±0.2V tolerance
• Current - Test: 20mA standard
• Millicandela Rating: Brightness variation acceptable within application requirements
• Power Dissipation (Max): Within thermal design limits

The LTS-10804G from LITEON meets all critical matching parameters and operates within allowable electrical variations, qualifying it as a direct substitute for the obsolete NAG107PB.

Parameter Comparison

Engineering Selection Recommendations

The LTS-10804G from LITEON is a qualified substitute for the obsolete NAG107PB based on the following engineering criteria:

Mechanical Compatibility: Both components share identical physical dimensions (1.299" H x 0.898" W x 0.354" D), digit height (1.00"), and 14-DIP package configuration, ensuring direct PCB footprint compatibility without layout modifications.

Electrical Compatibility: The LTS-10804G operates at 4.2V forward voltage compared to the NAG107PB's 4.4V, representing a 0.2V difference within standard design tolerances. Both components maintain 20mA test current and 565nm peak wavelength, ensuring consistent green color appearance and circuit behavior.

Functional Equivalence: Both devices are single-character, common anode 7-segment displays with identical display type and color specification, supporting the same numeric and alphanumeric display functions.

Product Status Advantage: The LTS-10804G holds active product status with RoHS3 compliance and MSL 1 rating, providing long-term availability and regulatory alignment for new production designs.

Brightness Consideration: The LTS-10804G provides 6mcd brightness compared to the NAG107PB's 8mcd. This 2mcd reduction is acceptable for applications where the original brightness specification does not represent a critical functional requirement. Applications requiring the original 8mcd brightness level should evaluate brightness-specific alternatives.

Frequently Asked Questions (FAQ)

Q: Can the LTS-10804G replace the NAG107PB in existing designs without circuit modification?

A: Yes. The LTS-10804G is mechanically and electrically compatible with the NAG107PB. Both components share identical physical dimensions, 14-DIP package configuration, common anode pin arrangement, and 20mA test current. The 0.2V forward voltage difference (4.2V vs 4.4V) falls within standard design tolerances and does not require circuit redesign.

Q: What is the significance of the brightness difference between these components?

A: The NAG107PB provides 8mcd brightness while the LTS-10804G provides 6mcd. This 2mcd reduction represents approximately 25% lower brightness. For applications where display brightness is a critical specification, this difference must be evaluated against actual application requirements. For general numeric display applications, this brightness level is typically acceptable.

Q: Are there any compliance or regulatory differences between these parts?

A: The LTS-10804G carries RoHS3 compliance and MSL 1 rating, while the NAG107PB is classified as obsolete. For new designs subject to RoHS regulations or requiring long-term component availability, the LTS-10804G provides regulatory alignment and supply chain continuity.

Q: Will the LTS-10804G work in circuits designed for the NAG107PB without testing?

A: The LTS-10804G is electrically and mechanically equivalent to the NAG107PB within specified parameters. However, application-specific validation is standard engineering practice for any component substitution, particularly regarding brightness performance in the target application environment.

Q: What is the lead configuration difference noted in the LTS-10804G specification?

A: The LTS-10804G specification references "10 Leads" within the 14-DIP package notation. Both components use standard 14-DIP package configuration with identical pin assignments for 7-segment display operation. This notation variation does not affect functional or mechanical compatibility.
