STD_320_BLK LED Holder Tri-Lead Black Equivalent & Substitute Parts

Part Overview

The STD_320_BLK is a tri-lead LED standoff holder manufactured by Visual Communications Company (VCC) with a 0.320" (8.13mm) length specification. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The part functions as a mechanical mounting interface for tri-lead LED packages, providing standardized spacing and alignment in electronic assemblies.

Due to the obsolete status of the STD_320_BLK, active substitute parts with identical or compatible electrical and mechanical parameters are necessary to maintain production capability and support legacy system repairs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STD_320_BLK is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Length: 0.320" (8.13mm) — exact match required for PCB mounting compatibility
• LED Configuration: Tri-Lead or compatible multi-lead types (T1, T1 3/4 acceptable for tri-lead applications)
• Color: Black — material and visual consistency
• RoHS Compliance: ROHS3 Compliant — regulatory requirement
• Tariff Classification: HTSUS 3926.90.9985 — commodity code alignment

Substitute Parts Identified:

1. LTM-320 (Bivar Inc.) — Similar manufacturer part with active product status, supporting T1 and T1 3/4 LED types within the tri-lead category
2. 8911 (Keystone Electronics) — Parametric equivalent with tri-lead LED specification and active product status

Both substitute parts meet all primary substitution criteria and maintain ROHS3 compliance and identical tariff classification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The LTM-320 (Bivar Inc.) and 8911 (Keystone Electronics) are both qualified substitutes for the obsolete STD_320_BLK based on parametric equivalence. Both parts maintain:

• Identical 0.320" (8.13mm) mounting height
• Tri-lead LED interface compatibility
• ROHS3 compliance
• Matching tariff and export control classifications
• Active product status ensuring long-term availability

Selection Considerations Based on Provided Data:

• LTM-320: Active status with Crystalline Polymer construction; available in Bag packaging; MSL rating 1 (Unlimited)
• 8911: Active status with PVC construction; available in Bulk packaging; MSL rating 1 (Unlimited); higher inventory availability (8675 Pcs)

Both parts are suitable for direct substitution in applications requiring the STD_320_BLK specification. Material differences (Crystalline Polymer vs. PVC) are documented but do not affect the core substitution criteria provided.

Frequently Asked Questions (FAQ)

Q: Can LTM-320 and 8911 be used interchangeably with STD_320_BLK?

A: Yes. Both parts meet all primary substitution criteria: identical 0.320" (8.13mm) length, tri-lead LED compatibility, black color, ROHS3 compliance, and matching tariff classification. Both are active products, providing supply continuity for the obsolete STD_320_BLK.

Q: What is the significance of the 0.320" length specification?

A: The 0.320" (8.13mm) length is a critical mechanical dimension that determines the standoff height from the PCB surface. All qualified substitutes maintain this exact specification to ensure proper LED package alignment and clearance in the original application.

Q: Are there differences in material composition between the substitutes?

A: Yes. The STD_320_BLK material is not specified in the provided data. The LTM-320 uses Crystalline Polymer, while the 8911 uses PVC. Both materials are ROHS3 compliant and suitable for the LED holder application category.

Q: What packaging options are available?

A: LTM-320 is supplied in Bag packaging, while 8911 is supplied in Bulk packaging. Packaging selection depends on procurement volume and handling requirements.

Q: Do the substitute parts have different moisture sensitivity levels?

A: The STD_320_BLK lists MSL as Not Applicable. Both substitute parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are export and tariff classifications identical across all three parts?

A: Yes. All three parts share identical ECCN (EAR99) and HTSUS (3926.90.9985) classifications, ensuring consistent regulatory and trade compliance.
