Substitute Part Grouping Explanation

Substitute parts for the 923-341 have been categorized based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

LED Type: T1 (all substitutes maintain this specification)
Length: 0.400" (10.16mm) or within 0.025" tolerance (9.91mm to 10.29mm)
Material: Nylon or PVC (both are acceptable for mechanical compatibility)
Color: Black (all substitutes maintain black finish)
Moisture Sensitivity Level: 1 (Unlimited) (all substitutes meet this requirement)

Substitute Parts:

Series 922 Parts (922-340, 922-341, 922-342, 922-343): Active status Bivar Inc. equivalents with identical specifications. RoHS3 compliance certified.
ELM 2 Series Parts (ELM 2-385, ELM 2-390, ELM 2-395, ELM 2-400, ELM 2-405, ELM 2-10MM): Active status alternatives with PVC material instead of nylon. Length variations accommodate design tolerances within the allowable range.

Engineering Selection Recommendations

First Priority: Series 922 Substitutes

The Series 922 parts (922-340, 922-341, 922-342, 922-343) are the direct parametric equivalents to the obsolete 923-341. All maintain identical nylon material composition, 0.400" length, and T1 LED specification. These parts carry active product status and RoHS3 compliance certification, making them suitable for new designs and production continuance. Current inventory levels across the Series 922 range are adequate for sustained supply (2,702 units combined).

Secondary Option: ELM 2 Series Substitutes

The ELM 2 series parts provide functional alternatives with PVC material substitution for nylon. Length variations in this series (0.385" to 0.405") accommodate mechanical tolerance bands around the nominal 0.400" specification. ELM 2-400 provides exact length matching with PVC material. All ELM 2 alternatives carry active status and RoHS3 compliance. These parts are appropriate when nylon-specific material requirements do not apply or when PVC material compatibility with the application is established.

All identified substitutes maintain MSL Level 1 (Unlimited) rating, ECCN EAR99 classification, and RoHS3 compliance where applicable, ensuring regulatory and handling consistency with the original specification.

Frequently Asked Questions (FAQ)

Q1: Can Series 922 parts directly replace the obsolete 923-341?

The Series 922 parts (922-340, 922-341, 922-342, 922-343) are direct substitutes for the 923-341. They maintain identical electrical and mechanical parameters: T1 LED type, 0.400" length, nylon material, and black color. All series members carry active product status and RoHS3 compliance.

Q2: What is the difference between nylon and PVC material options in the ELM 2 series?

Both nylon (923-341, Series 922) and PVC (ELM 2 series) materials are acceptable for this product category based on the provided specifications. Material selection depends on application-specific requirements such as temperature range, chemical exposure, or mechanical stress. Both materials support the same T1 LED type and dimensional compatibility.

Q3: How do length variations in the ELM 2 series affect compatibility?

The ELM 2 series offers multiple length options from 0.385" (9.78mm) to 0.405" (10.29mm), providing 0.020" variation around the nominal 0.400" specification. This range accommodates standard mechanical tolerance requirements for LED standoff applications. ELM 2-400 provides exact 0.400" length matching.

Q4: Are all substitute parts RoHS3 compliant?

All identified substitute parts carry RoHS3 compliance certification. The original 923-341 part does not list RoHS status, but this requirement is satisfied across the entire Series 922 and ELM 2 substitute range.

Q5: Which substitute has the best inventory availability?

Series 922-341 offers the highest single-part inventory at 1,153 units. The ELM 2-400 provides 1,035 units. Both represent strong availability for production continuance. Combined Series 922 inventory totals 2,702 units across all four part numbers.
