Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3-535512-8 are identified based on strict electrical and mechanical parameter matching. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 84
• Mating pitch: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing: 0.100" (2.54mm)
• Mounting type: Through hole, right angle
• Termination method: Solder
• Fastening type: Push-pull
• Contact finish (mating): Gold
• Operating temperature range: -55°C ~ 125°C
• Material flammability: UL94 V-0

The Samtec Inc. BCS-142-S-D-HE meets all critical matching parameters and qualifies as a direct substitute. Both connectors share identical position count, pitch spacing, mounting configuration, and environmental ratings. Differences in insulation height, contact post length, and current rating do not preclude substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The Samtec BCS-142-S-D-HE is a qualified substitute for the TE Connectivity 3-535512-8 based on matching critical electrical and mechanical parameters. Both connectors share identical position count, pitch spacing, row configuration, mounting orientation, and environmental operating range.

Product Status Consideration: The 3-535512-8 is discontinued at DiGi Electronics, while the BCS-142-S-D-HE maintains active product status with current inventory availability. This status difference supports the use of the Samtec part for new designs and ongoing production requirements.

Compliance Advantage: The BCS-142-S-D-HE is ROHS3 compliant and REACH unaffected, whereas the 3-535512-8 is RoHS non-compliant and REACH affected. For applications subject to regulatory compliance requirements, the Samtec substitute provides improved compliance posture.

Current Rating: The BCS-142-S-D-HE supports 4.6A per contact, exceeding the 2A rating of the 3-535512-8. Applications operating within the original 2A specification will function within the substitute part's electrical envelope.

Physical Dimensions: Minor differences exist in insulation height (0.238" versus 0.210") and contact post length (0.115" versus 0.125"). PCB layout and mating interface compatibility must be verified for specific applications to ensure these dimensional variations do not create mechanical interference or clearance issues.

Frequently Asked Questions (FAQ)

Q: Can the Samtec BCS-142-S-D-HE directly replace the TE Connectivity 3-535512-8 in existing designs?

A: The BCS-142-S-D-HE matches all critical connector parameters including position count, pitch, row spacing, mounting type, and environmental ratings. However, the 0.028" difference in insulation height and 0.010" difference in contact post length require verification against specific PCB layout and mating interface requirements. Physical fit validation is necessary before implementation.

Q: What are the key electrical differences between these two connectors?

A: Both connectors feature gold-plated mating contacts with identical 30.0µin (0.76µm) thickness and phosphor bronze contact material. The primary electrical difference is current rating: the 3-535512-8 is rated at 2A, while the BCS-142-S-D-HE is rated at 4.6A per contact. The BCS-142-S-D-HE also specifies a 475VAC voltage rating, which is not provided for the 3-535512-8.

Q: Are there packaging differences between these parts?

A: The 3-535512-8 packaging information is not specified in the available data. The BCS-142-S-D-HE is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: What compliance advantages does the Samtec part offer?

A: The BCS-142-S-D-HE is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to European Union regulatory requirements. The 3-535512-8 is RoHS non-compliant and REACH affected, which may restrict its use in regulated markets or applications with compliance mandates.

Q: How do the insulation materials differ?

A: The 3-535512-8 uses polyester glass-filled insulation, while the BCS-142-S-D-HE uses liquid crystal polymer (LCP) glass-filled insulation. Both materials meet UL94 V-0 flammability requirements and support the identical -55°C to 125°C operating temperature range.

Q: Is the higher current rating of the BCS-142-S-D-HE a concern for applications designed for 2A operation?

A: No. The BCS-142-S-D-HE's 4.6A per contact rating exceeds the original 2A specification, providing additional electrical capacity. Applications designed for 2A operation will function within the substitute part's electrical specifications without modification.

Q: What should be verified before implementing the Samtec substitute in production?

A: Verify PCB layout compatibility with the 0.028" insulation height difference and 0.010" contact post length difference. Confirm mating interface clearances and connector seating depth. Validate that the substitute part's electrical and environmental ratings meet or exceed application requirements. Perform functional testing with representative mating connectors to ensure proper engagement and contact reliability.
