Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 861400021YO2 is determined by strict equivalence across the following critical parameters:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Pitch specification (0.100" / 2.54mm)
• Number of positions (2)
• Number of rows (1)
• Mounting method (Through Hole)
• Termination type (Solder)
• Current and voltage ratings (3A / 1000V)
• Contact material and finish specifications
• Insulation material and flammability rating (UL94 V-0)

The substitute part 861400021YO2LF maintains identical electrical and mechanical specifications while differing in product status (active vs. obsolete) and RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 861400021YO2LF serves as the direct active equivalent to the obsolete 861400021YO2. Both parts share identical electrical and mechanical specifications, ensuring functional interchangeability in circuit designs and PCB layouts.

The primary distinction is regulatory compliance: the 861400021YO2LF carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. For applications subject to RoHS directives or requiring compliance documentation, the 861400021YO2LF is the appropriate selection. The substitute part also provides documented operating temperature range (-55°C ~ 125°C), offering explicit thermal performance parameters absent from the original specification.

Both parts maintain identical moisture sensitivity classification (MSL 1), current and voltage ratings, contact materials, and flammability ratings. Mechanical compatibility is assured across all dimensional and fastening specifications.

Frequently Asked Questions (FAQ)

Q: Can 861400021YO2LF be used as a direct replacement for 861400021YO2?

A: Yes. Both parts are electrically and mechanically identical. The substitute maintains the same 2-position, 0.100" pitch header configuration, solder termination, 3A current rating, and 1000V voltage specification. The primary difference is product status and RoHS compliance.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Obsolete status indicates the 861400021YO2 is no longer manufactured or supported by Amphenol ICC. The 861400021YO2LF, classified as Active, remains in current production with ongoing availability and technical support. For new designs or ongoing procurement, the active part is the standard selection.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical characteristics. Both parts deliver identical electrical performance. RoHS3 compliance of the substitute part ensures conformance with current regulatory requirements in markets where such certification is mandatory.

Q: Are the packaging specifications different between these parts?

A: The main part specifies packaging as "-" (not defined), while the substitute is packaged in Bulk. Verify bulk packaging specifications against your assembly and handling requirements.

Q: Is the operating temperature specification critical for substitution?

A: The substitute part explicitly specifies -55°C ~ 125°C operating range. The original part does not provide this specification. If your application requires documented thermal performance within this range, the substitute part provides explicit certification. If your application operates outside this range, verify compatibility with Amphenol ICC technical documentation.
