Substitute Part Grouping Explanation

Substitute parts for the H-133C-2-180 are grouped based on the following critical parameters:

Core Compatibility Parameters:

LED Type: T1 (all substitutes must accommodate T1 LED form factor)
Length: 0.310" (7.87mm) nominal dimension
Material: Nylon or equivalent rigid polymer (PVC acceptable as functional equivalent)
Color: Black
Moisture Sensitivity Level: 1 (Unlimited)

Grouping Logic:

Group 1 – Direct Series Equivalent: H-132C-1-180 represents the closest functional equivalent within the H132C series, maintaining identical external dimensions, T1 LED compatibility, nylon construction, and black coloring. This part is active in production status.

Group 2 – Parametric Equivalents (ELM 2 Series): Parts ELM 2-310, ELM 2-320, ELM 2-315, and ELM 2-325 share the same T1 LED accommodation and provide length variations within a narrow dimensional tolerance band (0.295" to 0.325"). These utilize PVC material instead of nylon but maintain functional compatibility for T1 LED mounting applications.

Group 3 – Extended Parametric Equivalents (ELM 4 Series): Parts ELM 4-295 and ELM 4-300 provide additional length options within the T1 LED standoff category, with PVC construction and comparable mechanical properties.

Engineering Selection Recommendations

Primary Replacement: H-132C-1-180 is the preferred substitute for H-133C-2-180. This part maintains identical T1 LED accommodation, length, and nylon construction, with the additional advantage of active production status and ROHS3 compliance. No design modification is required for this substitution.

Secondary Substitutes: The ELM 2-310 and ELM 2-8MM parts provide functional equivalence with identical 0.310" (7.87mm) length specifications. These utilize PVC material instead of nylon but maintain T1 LED compatibility and full MSL compliance. Both are active in production with ROHS3 certification.

Extended Height Variants: Parts ELM 2-305, ELM 2-315, ELM 2-320, and ELM 2-325 accommodate applications requiring different standoff heights within the T1 LED mounting category. ELM 2-315 and ELM 2-320 demonstrate the highest inventory availability (7562 and 26182 units respectively), indicating superior supply chain continuity.

Lower Height Options: ELM 2-295, ELM 4-295, and ELM 4-300 serve applications requiring reduced standoff heights while maintaining full T1 LED and MSL 1 compliance.

Frequently Asked Questions (FAQ)

Q: Can H-132C-1-180 be used as a direct replacement for H-133C-2-180?

A: Yes. Both parts share identical T1 LED type, 0.310" (7.87mm) length, nylon material composition, black color, and MSL 1 rating. H-132C-1-180 is currently in active production status.

Q: What is the difference between H-132C-1-180 (nylon) and ELM 2-310 (PVC) substitutes?

A: Both parts provide T1 LED accommodation with identical 0.310" (7.87mm) length and MSL 1 compliance. The material difference (nylon versus PVC) does not affect electrical performance. The choice depends on application requirements for mechanical rigidity and temperature tolerance. ELM 2-310 maintains active production status with ROHS3 compliance.

Q: Are height variations acceptable if the nominal length differs from the original 0.310" specification?

A: Height substitution is application-dependent. The provided parametric equivalents (ELM 2 and ELM 4 series) accommodate various lengths from 0.295" to 0.325". Selection must align with the LED positioning requirements of the target circuit board assembly.

Q: What inventory levels should be considered when selecting substitutes?

A: ELM 2-320 maintains the highest inventory (26182 units), followed by ELM 2-315 (7562 units). These parts offer superior supply chain stability for volume applications. H-132C-1-180 maintains 1101 units of active stock.

Q: Are all listed substitutes RoHS compliant?

A: H-132C-1-180 and all ELM series parts listed are ROHS3 compliant. The original H-133C-2-180 does not specify RoHS status due to its obsolete classification.
