Substitute Part Grouping Explanation

Substitute parts for the 3HC-201-S must satisfy the following electrical and mechanical criteria to ensure functional compatibility:

Critical Parameters for Substitution:

• Color: Red
• Mounting Type: Through Hole
• Lens Size: 3mm, T-1
• Voltage - Forward (Vf): 2V nominal
• Current - Test: 20mA
• Package / Case: Radial
• Lens Transparency: Clear

The identified substitute parts are categorized as follows:

3SRC-F (Parametric Equivalent): Active status Bivar Inc. component with forward voltage of 1.7V, 60mcd brightness, and 5.30mm maximum height. Maintains T-1 form factor and through-hole radial configuration.

WP710A10EC (Similar): Active status Kingbright component with forward voltage of 2V, 30mcd brightness, 34° viewing angle, and 5.90mm maximum height. Maintains T-1 form factor and through-hole radial configuration.

Parameter Comparison

Engineering Selection Recommendations

3SRC-F: Select this active Bivar Inc. substitute for designs requiring direct manufacturer continuity. The component is RoHS3 Compliant and carries ECCN EAR99 classification. The 1.7V forward voltage differs from the main part specification, requiring circuit-level voltage compatibility assessment. The 60mcd brightness rating exceeds the original specification.

WP710A10EC: Select this active Kingbright substitute for designs where forward voltage matching is required. The component is RoHS3 Compliant, REACH Unaffected, and carries ECCN EAR99 classification. The 30mcd brightness rating is lower than the original specification. The 34° viewing angle is wider than the original 20° specification and may affect optical design integration.

Frequently Asked Questions (FAQ)

Q: What makes 3SRC-F and WP710A10EC suitable substitutes for 3HC-201-S?

A: Both substitutes maintain the critical mechanical parameters: 3mm T-1 lens size, through-hole radial package, and clear lens transparency. Both operate at the 20mA test current. The substitutes are actively manufactured, addressing the obsolescence of the original part.

Q: How do the forward voltage differences impact substitution?

A: The 3SRC-F operates at 1.7V compared to the 3HC-201-S 2V specification. The WP710A10EC matches the 2V specification. Circuit designs must accommodate the voltage difference when selecting between these options, particularly in current-limiting resistor calculations and power supply margin considerations.

Q: Why do brightness ratings differ between the main part and substitutes?

A: The 3SRC-F provides higher brightness (60mcd versus 50mcd), while the WP710A10EC provides lower brightness (30mcd versus 50mcd). The difference reflects manufacturing variations across component series and suppliers. Design applications must assess whether the brightness variation is acceptable for the intended indicator function.

Q: How do the viewing angles affect component selection?

A: The 3HC-201-S and 3SRC-F both specify 20° viewing angles, providing narrow directional indication. The WP710A10EC specifies 34° viewing angle, providing wider visibility. Selection depends on the optical design requirements of the application.

Q: Are there packaging or compliance differences between substitutes?

A: The 3SRC-F is supplied in bulk packaging, while the WP710A10EC is supplied in bulk packaging. Both substitutes carry RoHS3 Compliance and ECCN EAR99 classification. The WP710A10EC carries additional REACH Unaffected status. Both maintain unlimited moisture sensitivity level (MSL 1).
