Key Parameters

Substitute Part Grouping Explanation

Substitution of the 51908-006 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type: Receptacle, Female Blade Sockets
• Number of positions: 3
• Contact layout: 3 Power
• Pitch: 0.300" (7.62mm)
• Termination method: Quick Connect, Disconnect
• Contact finish: Gold at 30.0µin (0.76µm)

Mechanical Compatibility Parameters:

• Connector style: Blade Power
• Number of rows: 1
• Operating temperature range: -20°C ~ 105°C
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 51908-006LF maintains complete equivalence across all electrical and mechanical parameters. The primary distinction is product status (active vs. obsolete) and RoHS compliance status, with the substitute offering RoHS compliance and active availability.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: The 51908-006LF is the appropriate selection for all applications currently using or specifying the 51908-006. This substitute provides:

• Complete electrical and mechanical equivalence across all critical parameters
• Active product status with established supply chain availability
• RoHS compliance, meeting current regulatory requirements for electronic components
• Identical connector interface, pitch, and contact specifications ensuring direct mechanical and electrical compatibility

For Legacy System Maintenance: The 51908-006 remains functionally equivalent to the 51908-006LF for systems already deployed. However, procurement of the obsolete 51908-006 is subject to inventory availability. The 51908-006LF should be specified for replacement and maintenance activities to ensure long-term supply continuity.

Compliance Considerations: Systems subject to RoHS regulations should transition to the 51908-006LF. The substitute maintains all electrical and mechanical performance characteristics while satisfying current compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 51908-006LF be used as a direct replacement for the 51908-006?

A: Yes. The 51908-006LF is electrically and mechanically equivalent to the 51908-006 across all specified parameters, including connector type, number of positions, pitch, termination method, contact finish, operating temperature range, and flammability rating. The parts are interchangeable in applications.

Q: What is the difference between the 51908-006 and 51908-006LF?

A: The primary differences are product status and compliance. The 51908-006 is obsolete and RoHS non-compliant, while the 51908-006LF is an active product with RoHS compliance. The 51908-006LF is also supplied in tray packaging and features a black color designation. All electrical and mechanical specifications remain identical.

Q: Why is the 51908-006 listed as obsolete?

A: The 51908-006 has been superseded by the 51908-006LF in the manufacturer's product line. The substitute offers improved compliance status and active availability while maintaining complete functional equivalence.

Q: Are there any compatibility concerns when switching from 51908-006 to 51908-006LF?

A: No compatibility concerns exist. Both parts share identical connector interfaces, pitch specifications (0.300" / 7.62mm), contact layouts (3 Power), and operating parameters (-20°C ~ 105°C). The parts are mechanically and electrically interchangeable.

Q: What does the "LF" designation in 51908-006LF indicate?

A: The "LF" suffix typically indicates lead-free or RoHS-compliant variants in component nomenclature. The 51908-006LF is RoHS compliant, distinguishing it from the non-compliant 51908-006.

Q: Is the 51908-006 still available for purchase?

A: The 51908-006 is classified as obsolete. While limited inventory may remain available through component distributors, the 51908-006LF should be specified for new procurement to ensure supply continuity and compliance with current regulations.

Q: What is the operating temperature range for both parts?

A: Both the 51908-006 and 51908-006LF operate across the identical temperature range of -20°C to 105°C, ensuring thermal compatibility in equivalent applications.

Q: Are both parts rated for the same flammability standard?

A: Yes. Both the 51908-006 and 51908-006LF meet the UL94 V-0 material flammability rating, providing equivalent fire safety performance.
