Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 146894-1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Number of Positions: 64
• Pitch: 0.039" (1.00mm)
• Number of Rows: 2
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)

Mechanical Compatibility Parameters:

• Connector Type: Receptacle, Outer Shroud Contacts
• Mounting Type: Surface Mount
• Height Above Board: 0.287" (7.30mm)
• Mated Stacking Heights: 11mm, 12mm
• Features: Board Guide
• Series: Free Height (FH) IEEE 1386, PMC

Regulatory & Compliance Parameters:

• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8536.69.4040

Substitute parts must maintain identical values across all electrical and mechanical parameters. Variations in packaging format (Bulk versus Cut Tape) and RoHS compliance status do not affect functional interchangeability at the component level.

Engineering Selection Recommendations

Primary Selection: 146894-1

The 146894-1 is the original specification part and remains the first choice for applications where the original part number is explicitly required by design documentation or procurement specifications. This part is Active in product status with 712 units in stock.

Substitute Selection: 5146894-1

The 5146894-1 serves as a direct functional substitute when the following conditions apply:

1. Packaging Format Requirement: When Cut Tape (CT) packaging is required instead of Bulk packaging for automated assembly processes or inventory management systems.

2. RoHS3 Compliance Requirement: When ROHS3 compliance certification is mandated by customer specifications, regulatory requirements, or supply chain policies. The 5146894-1 carries ROHS3 Compliant status, whereas the 146894-1 is RoHS non-compliant.

3. Inventory Availability: When the 146894-1 becomes unavailable, the 5146894-1 provides equivalent electrical and mechanical performance with higher inventory availability (1185 units in stock versus 712 units).

Both parts maintain identical electrical and mechanical specifications, including connector type, position count, pitch, mounting configuration, contact finish, and dimensional characteristics. Selection between these parts depends on packaging format and compliance certification requirements rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 146894-1 and 5146894-1 electrically interchangeable?

A: Yes. Both parts are 64 Position Connector Receptacles with identical electrical specifications, including 0.039" (1.00mm) pitch, gold contact finish at 30.0µin (0.76µm) thickness, and equivalent signal integrity characteristics within the Free Height (FH) IEEE 1386 and PMC series standards.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies components in loose form, suitable for manual assembly or small-volume applications. Cut Tape (CT) packaging supplies components on continuous tape cut into specific lengths, optimized for automated pick-and-place assembly equipment and high-volume manufacturing processes. The functional component remains identical; only the delivery format differs.

Q: Does RoHS compliance affect component performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both the RoHS non-compliant 146894-1 and ROHS3 Compliant 5146894-1 deliver identical connector functionality. Selection depends on regulatory requirements applicable to the end application or supply chain.

Q: Can I use the 5146894-1 in place of the 146894-1 on existing PCB designs?

A: Yes. The 5146894-1 maintains identical mechanical dimensions, mounting type (Surface Mount), height above board (0.287" / 7.30mm), and mated stacking heights (11mm, 12mm). No PCB layout modifications are required.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates Unlimited moisture sensitivity, meaning the component has no moisture absorption limitations and requires no special handling, storage, or baking procedures prior to assembly. Both substitute parts carry this same MSL rating.

Q: Are there any restrictions on using these connectors in specific applications?

A: Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4040, indicating standard commercial rectangular connector classification with no additional export or application restrictions beyond standard regulatory compliance.
