Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 66255-5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Series: Multimate XII
• Pin or Socket: Pin
• Contact Termination: Crimp
• Wire Gauge: 12-16 AWG
• Contact Material: Copper
• Contact Finish Thickness: 50.0µin (1.27µm)
• Packaging: Cut Tape (CT)
• Manufacturer: TE Connectivity Aerospace, Defense and Marine

Allowable Variation:

• Contact Finish: Tin-Lead to Tin (substitution permitted due to functional equivalence in power contact applications)
• Type: Power to Power, Stamped (stamped construction is compatible with crimp termination in this series)
• RoHS Status: Non-compliant to ROHS3 Compliant (upgrade path for regulatory requirements)

The substitute part 1-66255-2 meets all mandatory parameters and represents an upgrade in regulatory compliance while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For RoHS Compliance Requirements: Select part 1-66255-2. This substitute achieves ROHS3 compliance while maintaining identical electrical and mechanical specifications. Both parts share the same wire gauge rating (12-16 AWG), contact material (copper), finish thickness (50.0µin), and termination method (crimp).

For Legacy System Compatibility: The original part 66255-5 remains suitable for applications where RoHS compliance is not mandated. Both parts are Active status and maintain identical MSL ratings and packaging formats.

For Inventory Optimization: Part 1-66255-2 offers higher stock availability (6691 pcs vs. 1373 pcs) while providing regulatory upgrade capability.

Both parts are classified as Active products with unlimited moisture sensitivity ratings and identical export control classifications (EAR99).

Frequently Asked Questions (FAQ)

Q: Can part 1-66255-2 directly replace 66255-5 in existing assemblies?

A: Yes. Both parts are pin contacts within the Multimate XII series with identical wire gauge ratings (12-16 AWG), crimp termination, copper material, and finish thickness (50.0µin). The contact finish differs (tin-lead versus tin), but this variation is functionally equivalent for power contact applications.

Q: What is the primary difference between these two parts?

A: The primary difference is contact finish material and RoHS compliance status. Part 66255-5 uses tin-lead finish and is RoHS non-compliant. Part 1-66255-2 uses tin finish and is ROHS3 compliant. Both maintain identical electrical performance specifications.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Cut Tape (CT) packaging, ensuring compatibility with standard component handling and assembly processes.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, specify 1-66255-2. For applications without RoHS mandates, either part is acceptable based on availability and cost considerations.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL rating 1 (Unlimited), indicating identical moisture sensitivity handling requirements.

Q: Are there any export control differences between these parts?

A: No. Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.
