SNT-100-BL-T-H Equivalent & Substitute Parts

Part Overview

The SNT-100-BL-T-H is a 2-position shunt connector manufactured by Samtec Inc., featuring an open top grip design with 0.100" (2.54mm) pitch and tin contact finish. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SNT-100-BL-T-H is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Series: SNT (same connector family)
• Number of Positions: 2 (1 x 2) configuration
• Pitch: 0.100" (2.54mm) grid spacing
• Type: Open Top, Grip design
• Gender: Female Sockets
• Contact Finish: Tin
• Current Rating: 4.3A per Contact
• Housing Material: Polybutylene Terephthalate (PBT)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The SNT-100-BK-T-H qualifies as a substitute based on matching all critical electrical and mechanical parameters. The primary difference is connector height (0.240" vs. 0.550") and color designation (black vs. blue), which do not affect electrical compatibility or functional performance in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The SNT-100-BK-T-H is a qualified substitute for the obsolete SNT-100-BL-T-H based on electrical and mechanical parameter equivalence. Both components maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory alignment for applications requiring these standards.

The SNT-100-BK-T-H offers the additional advantage of active product status with confirmed inventory availability (15,247 units), eliminating supply chain risk associated with obsolete component procurement. The height differential (0.240" vs. 0.550") must be evaluated against specific PCB layout and mechanical assembly constraints; this parameter does not affect electrical performance but may require design accommodation in space-constrained applications.

Color differentiation (black vs. blue) serves identification purposes only and does not impact functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can SNT-100-BK-T-H directly replace SNT-100-BL-T-H in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both components share identical pitch (0.100"), position count (2), contact rating (4.3A), and housing material specifications. The primary design consideration is the height difference: SNT-100-BK-T-H measures 0.240" compared to 0.550" for the original part. Verify that your PCB layout and mechanical assembly accommodate this reduced height before implementation.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity classification. Regulatory requirements are equivalent.

Q: Why is the SNT-100-BL-T-H obsolete while SNT-100-BK-T-H remains active?

A: Product status reflects manufacturer production and support decisions. The SNT-100-BK-T-H remains in active production with current inventory, making it the preferred choice for new procurement and ongoing system support.

Q: Does color affect electrical performance?

A: No. Color serves as a visual identifier only and does not influence electrical characteristics, current capacity, or contact resistance.

Q: What should I verify before substituting these parts?

A: Confirm that your PCB layout accommodates the 0.240" height of the SNT-100-BK-T-H. Verify that connector orientation and mating interface remain compatible. No electrical re-qualification is required due to parameter equivalence.
