Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-280 are qualified based on the following critical parameters: LED type (T1), lead configuration (2LD), color (Black), mounting orientation (vertical), RoHS3 compliance, and MSL rating (1). Length variations within the substitute group range from 0.280" to 0.285" (7.11mm to 7.24mm), representing a 0.005" tolerance differential. Material composition varies between PVC and Nylon across the substitute group. All substitute parts maintain identical electrical specifications, compliance certifications, and lead configurations, permitting functional interchangeability in applications where the specified length and material tolerances are acceptable.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and RoHS3 compliance, ensuring regulatory alignment with the primary part. The ELM 2-285 provides the closest substitution to the ELM 4-280, differing only in length by 0.005" (0.13mm) while maintaining identical PVC material composition and vertical mounting configuration. The H-101C and H-101C-1 parts introduce material variation (Nylon instead of PVC) and mounting orientation change (Right Angle instead of Vertical), requiring design verification for mechanical fit and functional compatibility. Selection between H-101C and H-101C-1 is determined by inventory availability and application-specific lead spacing requirements, as both parts share identical electrical and mechanical specifications. All substitute parts carry MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the ELM 2-285 directly replace the ELM 4-280 in all applications?

A: The ELM 2-285 differs from the ELM 4-280 by 0.005" in length (0.285" versus 0.280"). Both parts maintain identical PVC material composition, vertical mounting orientation, T1 LED type, and 2-lead configuration. Substitution is permissible in applications where the length tolerance of ±0.005" does not affect circuit board layout, component clearance, or LED positioning specifications.

Q: What is the primary difference between the ELM 4-280 and the H-101C series?

A: The H-101C and H-101C-1 parts differ from the ELM 4-280 in two critical parameters: material composition (Nylon versus PVC) and mounting orientation (Right Angle versus Vertical). These differences affect mechanical fit on the circuit board and LED lead positioning. Substitution requires verification that the right-angle mounting configuration and nylon material properties are compatible with the intended application.

Q: Are H-101C and H-101C-1 interchangeable?

A: Yes. The H-101C and H-101C-1 parts share identical electrical specifications, mechanical dimensions, material composition, compliance certifications, and MSL ratings. Selection between these two parts is based solely on inventory availability and procurement requirements.

Q: Do all substitute parts meet the same compliance standards as the ELM 4-280?

A: Yes. All substitute parts listed—ELM 2-285, H-101C, and H-101C-1—are RoHS3 compliant and carry MSL 1 ratings identical to the ELM 4-280. All parts are manufactured by Bivar Inc. and maintain Active product status.

Q: What packaging format is used for these parts?

A: All parts in this substitution group are supplied in Bag packaging format, consistent with standard component distribution for LED standoff assemblies.
