HDSP-3601 Equivalent & Substitute Parts

Part Overview

The HDSP-3601 is a single-character 7-segment LED display module manufactured by Broadcom Limited. This green display operates as a common anode configuration and is housed in a 14-DIP package with 0.30" character height. The component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for this display category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-3601 is determined by the following criteria:

• Display type must be 7-segment LED
• Single character configuration required
• Common anode pin configuration mandatory
• Green color specification
• 0.30" (7.62mm) character height
• 14-DIP package format
• Active product status
• RoHS3 compliance

The SA03-11GWA from Kingbright meets all primary functional and mechanical requirements. Electrical parameters (forward voltage, test current, and power dissipation) fall within acceptable ranges for common anode 7-segment display applications. Package dimensions show minor variation in depth (0.240" vs. 0.180"), which remains compatible with standard 14-DIP footprints.

Parameter Comparison

Engineering Selection Recommendations

Both the HDSP-3601 and SA03-11GWA maintain Active product status with full RoHS3 compliance and REACH unaffected classification. Selection between these parts is based on electrical performance requirements within the application circuit.

The HDSP-3601 operates at lower forward voltage (2.1V typical) and lower test current (10mA), resulting in higher maximum power dissipation (105mW). The SA03-11GWA operates at slightly elevated forward voltage (2.2V typical) and higher test current (20mA), with lower maximum power dissipation (62.5mW). The SA03-11GWA provides higher brightness output (11mcd vs. 2.7mcd).

Both parts share identical package footprints, common anode configuration, and wavelength characteristics within 1nm variation. Circuit design must accommodate the electrical parameter differences when selecting between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can SA03-11GWA replace HDSP-3601 in existing PCB designs?

A: Yes. Both parts use identical 14-DIP package footprints and common anode pin configuration. PCB layout compatibility is maintained. Circuit design must verify that forward voltage (2.1V vs. 2.2V) and test current (10mA vs. 20mA) differences are acceptable for the application's current-limiting resistor network.

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

A: The SA03-11GWA provides higher brightness (11mcd vs. 2.7mcd) and operates at higher test current (20mA vs. 10mA). Forward voltage is slightly higher (2.2V vs. 2.1V). Peak wavelength differs by 1nm (565nm vs. 566nm), which is imperceptible to human vision.

Q: Are both parts RoHS3 compliant?

A: Yes. Both HDSP-3601 and SA03-11GWA are ROHS3 Compliant with REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited).

Q: What determines substitution eligibility for 7-segment displays?

A: Substitution requires matching display type (7-segment), character count (1), character height (0.30"), common pin configuration (common anode), color (green), and package format (14-DIP). Both parts meet these criteria.

Q: Does package depth variation affect compatibility?

A: Package depth differs by 0.060" (HDSP-3601: 0.180" vs. SA03-11GWA: 0.240"). Both remain within standard 14-DIP specifications. Verify clearance in applications with height-constrained layouts.
