Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTS-5703AJS is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Display type: 7-Segment LED (single character)
• Digit size: 0.56" (14.22mm)
• Color: Yellow
• Common pin configuration: Common Cathode
• Package: 10-DIP (0.600", 15.24mm)
• Product status: Active

Electrical Operating Parameters:

• Forward voltage (Vf): 2.05V nominal (acceptable range: 2.0V to 2.1V)
• Test current: 20mA
• Wavelength range: 583nm to 588nm (yellow spectrum)

Compliance & Environmental:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

The HDSP-5703 manufactured by Broadcom Limited meets all primary substitution criteria and operates within the specified electrical parameters. Both parts share identical package geometry, pin configuration, and functional specifications within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: LTS-5703AJS (Lite-On Inc.)

Use as the first-choice component when supply is available. Active production status and established inventory (1063 pcs) support consistent procurement. ROHS3 compliance and MSL-1 rating confirm suitability for standard manufacturing and storage conditions.

Substitute Part: HDSP-5703 (Broadcom Limited)

Acceptable as a direct substitute when LTS-5703AJS availability is constrained. Both parts maintain active production status and identical RoHS3 compliance. The HDSP-5703 operates at 2.1V forward voltage (0.05V higher than LTS-5703AJS) and provides higher brightness (1.8mcd vs. 0.7mcd) and greater power dissipation rating (80mW vs. 40mW). These differences are within acceptable engineering tolerances for 7-segment display applications and do not require circuit redesign. Physical dimensions are equivalent within standard manufacturing tolerances. Both parts are pin-compatible in 10-DIP configuration.

Frequently Asked Questions (FAQ)

Q: Can HDSP-5703 be used as a direct replacement for LTS-5703AJS without circuit modification?

A: Yes. Both parts share identical package geometry, pin configuration, and functional specifications. The HDSP-5703 operates at 2.1V forward voltage compared to 2.05V for the LTS-5703AJS—a 0.05V difference within standard circuit design margins. No circuit redesign is required.

Q: What is the brightness difference between these two parts?

A: The HDSP-5703 provides 1.8mcd brightness compared to 0.7mcd for the LTS-5703AJS. The Broadcom part is approximately 2.6 times brighter. This difference may be visible in applications where display brightness is critical; however, both parts operate within the yellow 7-segment LED category specifications.

Q: Are the physical dimensions identical?

A: Dimensions are equivalent within standard manufacturing tolerances. LTS-5703AJS measures 0.673" H x 0.488" W x 0.315" D; HDSP-5703 measures 0.670" H x 0.495" W x 0.315" D. Maximum variation is 0.003 inches, which does not affect PCB layout or mechanical assembly.

Q: Do both parts require the same power supply voltage?

A: Both parts operate at similar forward voltages (2.05V and 2.1V respectively) and require identical 20mA test current. Existing power supply and current-limiting resistor designs remain valid for either part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both LTS-5703AJS and HDSP-5703 are ROHS3 compliant and carry MSL-1 (Unlimited) moisture sensitivity ratings, confirming suitability for standard manufacturing environments.

Q: What is the wavelength difference?

A: LTS-5703AJS operates at 588nm peak wavelength; HDSP-5703 operates at 583nm. Both wavelengths fall within the yellow spectrum and are visually indistinguishable in typical display applications.

Q: Can I use HDSP-5703 in high-temperature applications?

A: Thermal performance data is not provided in the component specifications. Consult manufacturer datasheets for operating temperature ranges and thermal derating curves if high-temperature operation is required.

Q: Which part should I specify for new designs?

A: Specify based on current supply availability and procurement lead times. Both parts are active production items suitable for new designs. Verify final selection with your component supplier regarding inventory and delivery schedules.
