P08-040SLTC-A-G Equivalent & Substitute Parts

Part Overview

The P08-040SLTC-A-G is a 40-position rectangular connector socket manufactured by 3M, designed for surface mount applications with outer shroud contacts and gold plating. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance requirements. The P08 series provides standardized connector solutions for applications requiring reliable electrical interconnection with consistent pitch and contact geometry.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P08-040SLTC-A-G is determined by the following critical parameters that must remain constant:

• Connector Type & Configuration: Socket with outer shroud contacts, 40 positions, 2-row arrangement
• Electrical Interface: 0.031" (0.80mm) pitch for mating compatibility
• Mounting Technology: Surface mount with board guide feature
• Contact Material & Finish: Gold plating at 8.00µin (0.203µm) thickness
• Environmental Classification: MSL 1 (Unlimited moisture sensitivity level)
• Manufacturer Consistency: 3M P08 series components

The P08-040SLT-B-G qualifies as a direct substitute based on matching all critical parameters. Variations in mated stacking heights and height above board do not preclude substitution, as these dimensions accommodate different connector plug configurations within the same series specification.

Engineering Selection Recommendations

The P08-040SLT-B-G is the qualified substitute for the obsolete P08-040SLTC-A-G. Selection of this substitute is supported by:

• Product Status: The substitute maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The P08-040SLT-B-G carries RoHS compliance certification, meeting current environmental and regulatory requirements for electronic component manufacturing.
• Electrical & Mechanical Compatibility: All critical parameters—connector type, position count, pitch, contact finish, and MSL rating—are identical between the main part and substitute.
• Physical Accommodation: The increased height above board (0.205" vs. 0.087") and extended mated stacking heights (6mm, 7mm, 8mm vs. 3mm, 4mm, 5mm) require verification against specific PCB layout and mating connector specifications to ensure clearance and mechanical fit within the application.

Frequently Asked Questions (FAQ)

Q: Can the P08-040SLT-B-G be used as a direct replacement for P08-040SLTC-A-G in existing designs?

A: The P08-040SLT-B-G matches all critical electrical and contact specifications. However, the increased height above board (0.205" vs. 0.087") must be evaluated against PCB layout constraints and mating connector clearance requirements. Physical verification is necessary before implementation.

Q: What is the significance of the different mated stacking heights?

A: Mated stacking heights define the vertical distance when the socket is mated with its corresponding plug connector. The P08-040SLT-B-G accommodates taller plug configurations (6mm, 7mm, 8mm) compared to the original part (3mm, 4mm, 5mm). Selection depends on the specific plug connector used in the application.

Q: Does the RoHS compliance status of the substitute affect compatibility?

A: RoHS compliance is a regulatory and environmental attribute that does not affect electrical or mechanical compatibility. The substitute's RoHS certification indicates compliance with current manufacturing standards and may be required for applications subject to RoHS regulations.

Q: Are there any differences in contact finish quality between the two parts?

A: Both parts specify identical gold plating thickness at 8.00µin (0.203µm), ensuring equivalent electrical contact performance and corrosion resistance.

Q: What is MSL 1 and why is it important?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited moisture sensitivity, meaning the component does not require special moisture control during storage, handling, or assembly. Both parts carry this classification, eliminating moisture management as a substitution concern.
