Key Parameters

Substitute Part Grouping Explanation

Substitution of the TDSG3151 with the TDSG3150-MN is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications for display type, character configuration, digit size, color, common anode topology, package form factor, forward voltage, test current, physical dimensions, maximum power dissipation, and peak wavelength. The substitution is valid because all parameters that determine functional compatibility remain constant between the two parts. The TDSG3150-MN differs only in millicandela rating (14mcd versus 9mcd) and product status (Active versus Obsolete), with the higher brightness rating representing an improvement in performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TDSG3150-MN is the appropriate substitute for the obsolete TDSG3151. Both parts maintain identical electrical and mechanical specifications, ensuring direct compatibility in existing circuit designs and PCB layouts. The TDSG3150-MN carries Active product status, providing long-term availability and supply chain stability. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The increased millicandela rating of the TDSG3150-MN (14mcd versus 9mcd) represents improved luminous intensity without requiring circuit modifications, as the forward voltage and test current remain constant.

Frequently Asked Questions (FAQ)

Q: Can the TDSG3150-MN be used as a direct replacement for the TDSG3151 in existing designs?

A: Yes. The TDSG3150-MN is electrically and mechanically identical to the TDSG3151 across all critical parameters including forward voltage, test current, package form factor, and physical dimensions. No circuit modifications are required.

Q: What is the difference between the TDSG3151 and TDSG3150-MN?

A: The primary differences are product status and brightness rating. The TDSG3151 is obsolete with 9mcd brightness, while the TDSG3150-MN is active with 14mcd brightness. All other electrical and mechanical specifications are identical.

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

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). They meet the same regulatory requirements.

Q: Does the higher brightness of the TDSG3150-MN affect circuit design?

A: No. The forward voltage (2.4V) and test current (20mA) remain identical between both parts. Existing circuit designs require no modification to accommodate the TDSG3150-MN.

Q: What packaging options are available for the TDSG3150-MN?

A: The TDSG3150-MN is supplied in Bulk packaging, maintaining the same 10-DIP (0.300", 7.62mm) form factor as the TDSG3151.
