HTST-116-01-L-D Equivalent & Substitute Parts

Part Overview

The HTST-116-01-L-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This vertical 32-position connector operates across a temperature range of -55°C to 125°C and features shrouded 4-wall construction with push-pull fastening. The part is currently active in production with 940 units in stock inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or supply constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTST-116-01-L-D is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (32 positions, 2 rows)
• Pitch specifications (0.100" mating pitch, 0.100" row spacing)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Contact material and finish (Phosphor Bronze with Gold mating finish)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Regulatory compliance (UL94 V-0, ROHS3)

The HTSS-116-01-L-D meets all these criteria and qualifies as a direct substitute. Both parts share identical mechanical and electrical characteristics within the specified parameters, differing only in series designation (HTST versus HTSS) and minor inventory/compliance variations.

Parameter Comparison

Engineering Selection Recommendations

Both the HTST-116-01-L-D and HTSS-116-01-L-D are active production parts manufactured by Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are functionally equivalent across all critical electrical and mechanical parameters. Selection between these two parts may be based on inventory availability, with the HTSS-116-01-L-D currently showing higher stock levels (1132 units versus 940 units). Both parts carry identical regulatory classifications (EAR99 export control, 8536.69.4040 HTSUS code) and are suitable for applications requiring through-hole rectangular connectors with 32-position, 2-row configuration and 2.54mm pitch spacing.

Frequently Asked Questions (FAQ)

Q: Can HTSS-116-01-L-D be used as a direct replacement for HTST-116-01-L-D?

A: Yes. Both parts meet identical specifications for connector type, contact configuration, pitch, mounting method, shrouding, fastening mechanism, contact materials, insulation material, operating temperature range, and regulatory compliance. The parts are mechanically and electrically interchangeable.

Q: What is the difference between the HTST and HTSS series designations?

A: The series designation reflects internal Samtec product line organization. Both HTST-116 and HTSS-116 base product numbers produce connectors with identical functional characteristics for this specific part number configuration.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts feature identical mating pitch (0.100"), row spacing (0.100"), contact geometry (square shape), contact materials (phosphor bronze), and mating surface finish (gold). PCB footprints and mating connector interfaces are identical.

Q: What is the current rating for these connectors?

A: The HTST-116-01-L-D is rated at 3.4A per contact. The HTSS-116-01-L-D current rating is not specified in the provided parameters.

Q: Are these parts suitable for high-temperature applications?

A: Both parts operate across the temperature range of -55°C to 125°C. Applications requiring operation outside this range require alternative components.

Q: What is the keying slot feature?

A: The keying slot is a mechanical feature that prevents incorrect mating orientation, ensuring proper connector alignment during assembly.

Q: Do these connectors require any special handling or storage conditions?

A: The HTST-116-01-L-D has no moisture sensitivity level (Not Applicable). The HTSS-116-01-L-D carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for either part.
