Keystone Electronics 7038 LED Holder T1 3MM - Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 7038 is a T1 LED standoff holder manufactured from natural nylon with a length of 0.260" (6.60mm). This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The 7038 serves as a mechanical mounting solution for T1 3mm LED packages in PCB assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 7038 is determined by the following critical parameters: LED type (T1), material (nylon), color (natural), and RoHS/REACH compliance. The substitute parts are grouped into two categories based on length compatibility:

Primary Substitute (Exact Length Match):

• Part 7359: Maintains the 0.260" (6.60mm) length specification, ensuring direct mechanical and electrical compatibility in existing PCB designs.

Parametric Equivalents (Reduced Length):

• Parts 7358, 7037, and LEDS1E-4-01: Feature a 0.250" (6.35mm) length, representing a 0.010" (0.25mm) reduction. These parts maintain T1 LED compatibility, nylon construction, and natural color but differ in standoff height.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory alignment with the original component.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Modification Required): Select Keystone Electronics 7359 when exact dimensional compatibility is required. The 7359 maintains the 0.260" (6.60mm) length specification and is currently in active production status with 5137 units in stock. This part carries ROHS3 compliance and MSL 1 rating, matching the original 7038 specifications.

For Parametric Substitution (Design Review Required): Parts 7358, 7037, and LEDS1E-4-01 are suitable when a 0.010" (0.25mm) reduction in standoff height is acceptable within the application. The 7358 and LEDS1E-4-01 are active production parts with substantial inventory availability (52816 and 2034 units respectively). Both maintain full regulatory compliance. The 7037 is obsolete and should not be selected for new designs.

Manufacturer Preference: Keystone Electronics parts (7359, 7358) are preferred for consistency with the original component source. Essentra Components LEDS1E-4-01 provides an alternative from an active manufacturer with equivalent electrical and mechanical properties.

Frequently Asked Questions (FAQ)

Q: Can the 7359 be used as a direct replacement for the 7038? A: Yes. The 7359 maintains identical length (0.260"), LED type (T1), material (nylon), and color (natural) specifications. Both parts are ROHS3 compliant and carry MSL 1 ratings. No design modification is required.

Q: What is the difference between the 7038 and the 7358? A: The primary difference is length: the 7038 is 0.260" (6.60mm) while the 7358 is 0.250" (6.35mm), a 0.010" reduction. Both are T1 nylon standoffs in natural color with identical compliance ratings. The 7358 is currently in active production.

Q: Is the LEDS1E-4-01 from Essentra Components fully compatible? A: The LEDS1E-4-01 matches the 7038 in LED type (T1), material (nylon), color (natural), and length (0.250"). It carries RoHS compliance and REACH unaffected status. The MSL rating is not applicable for this part. Compatibility depends on whether the 0.010" length difference is acceptable in your application.

Q: Why is the 7037 listed if it is obsolete? A: The 7037 is included as a parametric equivalent for reference purposes. It should not be selected for new designs or production. Use the 7359 or 7358 instead.

Q: What packaging options are available? A: The 7359, 7358, and LEDS1E-4-01 are supplied in bulk packaging. Original packaging information for the 7038 is not specified.

Q: Are all substitute parts REACH compliant? A: Yes. All listed substitute parts carry REACH unaffected status, matching the original 7038 specification.
