Keystone Electronics 7049 T1 LED Holder Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 7049 is a T1 LED standoff holder manufactured from natural nylon with a 0.450" (11.42mm) length. This component is classified as obsolete, necessitating identification of active alternative parts that maintain functional compatibility. The 7049 serves as a mechanical mounting solution for T1 3mm LED applications, providing standardized positioning and spacing in electronic assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7049 is determined by the following parameters: LED type (T1), material composition (nylon), color (natural), and compliance certifications (ROHS3, MSL 1, REACH Unaffected). Length variations within the T1 LED holder category are permissible when mechanical clearance and assembly geometry accommodate the dimensional difference. The primary substitute is Keystone Electronics 7370, which is active and maintains all critical parameters with a nominal length of 0.450" (11.43mm). Secondary parametric equivalents include 7048, 7050, and 7369, which share the core functional parameters but vary in length specification. Part 7371 from CEC Industries represents a different product category (lamp assembly) and is not a direct mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production requiring T1 LED holder functionality, Keystone Electronics 7370 is the primary recommended substitute. This part maintains active product status, ensuring long-term availability and supply chain continuity. The 7370 exhibits dimensional equivalence to the 7049 with a length variance of 0.01mm (11.43mm versus 11.42mm), which is within standard manufacturing tolerances for nylon molded components.

Keystone Electronics 7369 represents an alternative active source for T1 LED holders with a 0.440" (11.18mm) length specification. This part accommodates applications where reduced standoff height is acceptable within the assembly design constraints.

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory alignment with the original 7049 specification.

Frequently Asked Questions (FAQ)

Q: Can Keystone Electronics 7370 directly replace the 7049 in existing assemblies?

A: Yes. The 7370 is the manufacturer-recommended substitute with matching LED type (T1), material (nylon), color (natural), and length specification (0.450"). The 0.01mm dimensional difference is within standard manufacturing tolerance for nylon components and does not affect functional compatibility.

Q: What is the difference between the 7369 and 7370 substitutes?

A: Both are active Keystone Electronics T1 LED holders in natural nylon. The primary difference is length: 7369 measures 0.440" (11.18mm) while 7370 measures 0.450" (11.43mm). Selection depends on available mechanical clearance in the assembly. All other parameters—LED type, material, color, and compliance certifications—are identical.

Q: Why are 7048 and 7050 listed as parametric equivalents if they are obsolete?

A: These parts are included for reference in legacy system documentation and reverse-engineering applications. For new production, active alternatives (7370 or 7369) are required to ensure supply chain continuity and manufacturing support.

Q: Is CEC Industries 7371 a suitable substitute for the 7049?

A: No. The 7371 is a lamp assembly (12V T-1.75 with Bi-Pin base), representing a different product category. It is not a mechanical substitute for the 7049 LED holder.

Q: What packaging options are available for substitute parts?

A: Keystone Electronics 7370 and 7369 are supplied in bulk packaging, suitable for production assembly operations. The original 7049 was supplied without specified packaging designation.
