Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 3-535512-2 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• Contact Material: Phosphor Bronze

Allowable Variation Parameters:

• Number of Positions: 62 positions (substitute) versus 64 positions (main part)
• Contact Finish - Mating: Gold or Tin
• Current Rating: 4.6A per Contact (substitute) versus 2A (main part)
• Voltage Rating: 475VAC (substitute) versus unspecified (main part)
• Insulation Material: Liquid Crystal Polymer (LCP), Glass Filled (substitute) versus Polyester, Glass Filled (main part)
• RoHS Status: ROHS3 Compliant (substitute) versus RoHS non-compliant (main part)

The Samtec BCS-131-S-D-HE and BCS-131-T-D-HE connectors satisfy the mandatory matching parameters while offering enhanced electrical performance and regulatory compliance options.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 3-535512-2 Selection Criteria: The original TE Connectivity part is appropriate for applications where 64-position capacity is required and RoHS non-compliance is acceptable. This connector maintains Active product status with established supply availability.

Samtec BCS-131-S-D-HE Selection Criteria: This substitute is suitable for applications requiring ROHS3 compliance with gold-plated mating contacts. The 62-position configuration accommodates most applications requiring fewer connection points than the 64-position original. Enhanced current rating of 4.6A per contact and 475VAC voltage rating provide superior electrical performance. Liquid Crystal Polymer insulation material offers improved thermal and mechanical properties compared to polyester.

Samtec BCS-131-T-D-HE Selection Criteria: This substitute is suitable for applications requiring ROHS3 compliance with tin-plated mating contacts. The 62-position configuration and enhanced electrical ratings match the BCS-131-S-D-HE. Tin finish on mating contacts provides cost optimization while maintaining electrical performance specifications.

Both Samtec substitutes maintain Active product status and are available in current inventory. Selection between the two Samtec options depends on contact finish requirements: gold finish (BCS-131-S-D-HE) for enhanced corrosion resistance or tin finish (BCS-131-T-D-HE) for cost-optimized applications.

Frequently Asked Questions (FAQ)

Q: Can the Samtec BCS-131 series connectors directly replace the TE Connectivity 3-535512-2 in existing designs?

A: Direct replacement requires design verification due to position count reduction from 64 to 62 positions. The Samtec connectors maintain identical pitch, row spacing, mounting type, and fastening mechanism. Physical dimensions differ slightly in insulation height (0.210" versus 0.238") and contact post length (0.125" versus 0.115"), which must be evaluated against PCB layout constraints.

Q: What is the primary difference between BCS-131-S-D-HE and BCS-131-T-D-HE?

A: The primary difference is the mating contact finish. BCS-131-S-D-HE features gold-plated mating contacts identical to the original TE Connectivity part. BCS-131-T-D-HE features tin-plated mating contacts. Both connectors share identical electrical ratings, insulation materials, and mechanical specifications.

Q: Are the Samtec substitutes RoHS compliant?

A: Yes, both Samtec BCS-131-S-D-HE and BCS-131-T-D-HE are ROHS3 compliant. The original TE Connectivity 3-535512-2 is RoHS non-compliant. This represents a significant regulatory advantage for new designs or applications subject to RoHS requirements.

Q: What are the electrical performance improvements in the Samtec substitutes?

A: The Samtec BCS-131 series provides enhanced current rating of 4.6A per contact compared to 2A in the original part, and specifies a voltage rating of 475VAC. These improvements enable the connectors to handle higher power applications while maintaining the same physical form factor and pitch specifications.

Q: How does the insulation material differ between the original and substitute parts?

A: The original TE Connectivity 3-535512-2 uses polyester glass-filled insulation. The Samtec BCS-131 series uses Liquid Crystal Polymer (LCP) glass-filled insulation. LCP provides superior thermal stability, lower moisture absorption, and improved mechanical properties at elevated temperatures.

Q: Is the 2-position reduction from 64 to 62 positions a limiting factor?

A: Position count reduction must be evaluated against specific application requirements. Applications utilizing all 64 positions require design modification. Applications using fewer than 62 positions can accommodate the substitute without functional impact.

Q: What packaging options are available for the substitute parts?

A: Both Samtec BCS-131-S-D-HE and BCS-131-T-D-HE are supplied in tube packaging, matching the original TE Connectivity part packaging format. Current inventory availability is 907 pieces for BCS-131-S-D-HE and 716 pieces for BCS-131-T-D-HE.
